Cybersecurity affects almost every part of modern banking because banks now depend on digital systems to move money, store customer information, approve transactions, manage credit, communicate with clients and connect with other financial institutions.
A successful cyberattack can therefore do much more than steal data.
It can interrupt payments, lock customers out of accounts, expose personal information, disrupt lending, damage confidence and create large financial losses.
South African regulators increasingly treat cyber risk as a core financial-sector risk rather than simply an IT problem. The Prudential Authority and Financial Sector Conduct Authority now require regulated institutions to maintain formal cybersecurity and cyber-resilience controls under Joint Standard 2 of 2024 on Cybersecurity and Cyber Resilience, which took effect on 1 June 2025.
For someone building a career in finance, that creates an important change. Understanding banking increasingly means understanding technology risk, fraud, data, operational resilience and cybersecurity as well.
Why is cybersecurity so important to banks?
Banks hold three things criminals value enormously:
- Money
- Personal information
- Access to payment systems
They also operate services that customers expect to work continuously.
You expect to be able to:
- Pay with your card
- Transfer money
- Use a banking app
- Receive your salary
- Withdraw cash
- Approve transactions
- Access your accounts
If a bank’s technology becomes unavailable, everyday economic activity can be affected very quickly.
That makes cybersecurity both a customer-protection issue and a financial-stability issue.
Is cyber risk just an IT department problem?
No. Modern banking regulation increasingly treats cyber risk as an organisational responsibility.
The South African Reserve Bank’s Prudential Authority says in its 2026 communication on AI-accelerated cyber risk that cyber preparedness is a board-level and executive responsibility.
That means senior management needs to understand questions such as:
- Which systems are most critical?
- How quickly can an attack be detected?
- Who can shut down compromised systems?
- How will customers continue transacting?
- What happens if a cloud provider fails?
- How quickly can the bank recover?
- How much financial damage can the institution absorb?
The technical security team may operate the tools, but responsibility for the risk extends much further.
What is the difference between cybersecurity and cyber resilience?
Cybersecurity focuses on preventing, detecting and responding to cyber threats.
Cyber resilience goes further.
It asks whether the institution can continue operating and recover quickly even when an attack succeeds.
No bank can assume every attack will be blocked.
A resilient institution therefore plans for situations where:
- Systems are compromised
- Data becomes unavailable
- A supplier goes offline
- Credentials are stolen
- Ransomware spreads
- Fraud attempts increase suddenly
The goal is to limit the damage and restore essential services.
South Africa’s Joint Standard 2 of 2024 reflects this broader approach by covering both cybersecurity and the ability of financial institutions to withstand and recover from cyber incidents.
What kinds of cyber threats do banks face?
Banks face a wide range of threats.
These can include:
- Phishing
- Malware
- Ransomware
- Credential theft
- Remote access attacks
- Account takeover
- Distributed denial-of-service attacks
- Data breaches
- Insider threats
- Supply-chain attacks
- Cloud vulnerabilities
- API attacks
- Social engineering
- AI-powered fraud
The attack does not always begin with someone “hacking the bank”.
In many cases, criminals target the customer first.
What is phishing?
Phishing is an attempt to trick someone into giving away sensitive information or taking an unsafe action.
A fraudster might send a message that appears to come from:
- Your bank
- SARS
- A courier company
- An online store
- A mobile network
- An employer
The message may ask you to:
- Click a link
- Enter banking credentials
- Approve a payment
- Provide an OTP
- Download a file
- Call a fake support number
The aim is usually to obtain information or device access that can later be used to steal money.
What is vishing?
Vishing is phishing conducted by voice. A criminal may phone you pretending to be from the bank’s fraud department.
They might claim that:
- Your account is under attack
- A suspicious transaction needs to be cancelled
- Your card must be secured
- Your account must be moved to a “safe” account
The sense of urgency is deliberate.
A convincing criminal does not necessarily need to breach a banking system if they can persuade the customer to approve the transaction themselves.
What is smishing?
Smishing uses SMS or mobile messaging instead of email.
You might receive a message claiming that:
- Your account will be suspended
- You have a refund waiting
- A debit order needs verification
- A parcel could not be delivered
- A transaction is suspicious
The included link can lead to a fake website designed to capture credentials.
The page may look extremely similar to a genuine banking website.
Why is social engineering such a big banking threat?
Because people can sometimes be easier to manipulate than secure banking infrastructure.
The SABRIC 2024 banking crime statistics showed that digital banking fraud incidents rose sharply, with reported cases increasing by 86% during 2024 and gross losses rising by 74% to about R1.9 billion.
SABRIC also stressed that much of the fraud involved social engineering and manipulation of customers rather than direct compromise of core banking platforms.
That distinction matters.
A bank can have strong encryption and sophisticated cybersecurity systems while a criminal persuades a customer to hand over the information needed to bypass them.
What is account takeover?
Account takeover happens when a criminal gains enough access to operate someone’s financial account.
This can happen through stolen:
- Usernames
- Passwords
- PINs
- OTPs
- Session information
- Device access
Once inside, the criminal may attempt to:
- Transfer money
- Add beneficiaries
- Apply for credit
- Change contact details
- Purchase goods
- Move money through multiple accounts
Banks therefore monitor more than just passwords.
They can also analyse devices, transaction behaviour, locations and unusual activity patterns.
What are Remote Access Trojan attacks?
A Remote Access Trojan, or RAT, is malicious software that can allow an attacker to control another person’s device remotely.
SABRIC’s 2026 warning on RAT attacks describes them as a growing digital-fraud threat because criminals can effectively operate a compromised device as though they were the legitimate user.
That can be more dangerous than simply stealing a password.
If the criminal controls the device itself, they may be able to:
- View messages
- Capture login details
- Observe OTPs
- Open banking apps
- Control the screen
- Initiate transactions
Customers can sometimes unknowingly install remote-access software after being persuaded by someone pretending to provide technical or banking support.
What is ransomware?
Ransomware is malicious software that can encrypt or block access to systems and data.
The attacker then demands payment for restoring access or preventing stolen information from being released.
For a financial institution, ransomware can disrupt:
- Customer service
- Internal systems
- Payments
- Reporting
- Employee access
- Back-office operations
Even if customer money is not directly stolen, the operational disruption can be severe.
Banks therefore need recovery systems, backups and incident-response plans that do not depend on paying criminals.
What is a denial-of-service attack?
A distributed denial-of-service attack, or DDoS attack, attempts to overwhelm a digital service with traffic.
The goal may be to make a banking website or other online service unavailable.
Unlike some cyberattacks, the attacker may not be trying to enter the bank’s systems or steal information.
They may simply want to stop legitimate users from accessing the service.
Availability is a major part of banking security because a perfectly protected system is not useful if customers cannot access it.
What is a data breach?
A data breach occurs when information is accessed, exposed or removed without proper authorisation.
Financial institutions can hold data such as:
- ID numbers
- Contact information
- Addresses
- Account information
- Transaction histories
- Credit information
- Income details
- Documents
- Authentication information
A breach can therefore create risks long after the original incident.
Stolen personal data can later be used for:
- Identity theft
- Fraud applications
- Phishing
- Impersonation
- Account takeover
This is why cybersecurity and privacy are closely linked.
How can a cyberattack affect customer money?
There are several possible routes.
A criminal might:
- Take over an account
- Trick the customer into approving a transfer
- Steal card information
- Obtain banking credentials
- Compromise a device
- Redirect payments
- Apply for credit using stolen information
The customer may experience the incident as “money disappearing”, but the underlying attack can be very different.
That affects both how the bank investigates the incident and how it tries to prevent similar fraud.
Can criminals bypass banking security without hacking the bank?
Yes. A fraudster may persuade the legitimate customer to perform the transaction.
For example, a criminal pretending to be from the fraud department might tell you:
Move your money immediately to this secure account.
If you personally approve the transfer, normal security systems may initially see a legitimate customer using a recognised device.
This is one reason banks invest heavily in behavioural fraud detection in addition to traditional cybersecurity controls.
How do banks detect suspicious transactions?
Banks can use systems that analyse patterns in real time.
The systems may consider things such as:
- Transaction amount
- Beneficiary
- Device
- Location
- Time
- Customer history
- Transfer speed
- Login behaviour
- Previous fraud patterns
Suppose you normally make small payments in Johannesburg, then your account suddenly attempts several large transfers from an unfamiliar device.
That could trigger additional authentication or fraud monitoring.
The customer may experience this as an inconvenient security check, but the friction can be intentional.
Why do banks sometimes block legitimate transactions?
Fraud-detection systems work by identifying behaviour that looks unusual or risky. They cannot always know immediately whether the transaction is genuinely fraudulent.
This creates a trade-off. If security controls are too weak, fraud increases. If they are too aggressive, legitimate customers are constantly blocked.
Banks therefore try to balance:
- Security
- Customer convenience
- False fraud alerts
- Financial loss
That balance becomes more difficult as criminals copy ordinary customer behaviour more effectively.
How does cybersecurity affect card payments?
Card systems are a major cybersecurity and fraud target.
Risks can include:
- Stolen card information
- Card-not-present fraud
- Fake merchants
- Compromised payment pages
- Credential theft
- Account takeover
SABRIC’s banking crime reporting has consistently identified card-not-present transactions as an important source of card fraud.
Customers may never physically lose the card.
The information can be stolen and used remotely.
This is one reason banks increasingly provide controls such as:
- Virtual cards
- Transaction notifications
- Temporary card freezing
- Online transaction controls
- Spending limits
Are virtual cards safer?
They can reduce certain risks.
A virtual card may allow you to avoid exposing the details printed on your primary physical card during online purchases.
Some banks can also rotate security information or provide separate virtual cards for different uses.
But a virtual card is not immune to fraud.
If someone controls your banking profile or persuades you to disclose sensitive information, other protections can still be bypassed.
Security works best in layers.
What is multi-factor authentication?
Multi-factor authentication requires more than one type of proof before granting access.
The factors can include something you:
- Know, such as a password
- Have, such as your phone
- Are, such as a fingerprint or face
This makes a stolen password less useful by itself. But criminals increasingly try to steal or manipulate the second factor too.
For example, they may persuade a customer to approve a fraudulent banking-app request.
Multi-factor authentication therefore improves security but does not eliminate social engineering.
What is biometric banking security?
Biometric authentication uses physical characteristics such as:
- Fingerprints
- Facial recognition
- Voice characteristics
Biometrics can be convenient because the customer does not need to remember another password.
But the security system needs to be designed carefully.
Banks must consider threats including:
- Spoofing
- Stolen devices
- Deepfakes
- Weak enrolment processes
- Compromised biometric data
Biometrics are therefore normally one part of a broader security system rather than the only control.
How is AI changing financial cybercrime?
AI makes certain attacks faster and more convincing.
The Prudential Authority warned in its April 2026 communication on frontier AI and cyber risk that advances in AI are compressing the time institutions have to detect and respond to cyber threats.
AI can help criminals:
- Write convincing phishing messages
- Automate attacks
- Analyse stolen data
- Create fake identities
- Clone voices
- Generate fake images or video
- Adapt attacks rapidly
A poorly written scam email used to be easier to recognise.
AI can produce professional language instantly.
What are deepfake banking scams?
Deepfakes use AI to imitate someone’s appearance or voice.
A criminal could attempt to impersonate:
- A bank employee
- A company executive
- A family member
- A financial adviser
- A supplier
Imagine an employee receives what sounds like a voice note from the CFO requesting an urgent transfer.
If the voice is convincingly cloned, an ordinary “does this sound like the boss?” check may no longer be enough.
That increases the importance of independent verification procedures.
Can AI also help banks defend themselves?
Yes. Banks can use AI and machine learning for:
- Fraud detection
- Cyberattack detection
- Behaviour analysis
- Alert prioritisation
- Malware detection
- Transaction monitoring
- Incident investigation
The Prudential Authority noted in its 2024/25 Annual Report that larger South African banks were increasingly using AI to strengthen cybersecurity, automate responses and support predictive threat analysis.
The result is an arms race.
Criminals can use AI to improve attacks while banks use AI to detect them.
Why is identity becoming so important?
Many digital financial services ultimately depend on answering one question:
Is this really the customer?
Banks need to authenticate people when they:
- Open accounts
- Log in
- Transfer money
- Reset passwords
- Add devices
- Apply for credit
- Change personal information
Identity fraud becomes more difficult to manage as criminals gain access to stolen personal information and AI-generated documents.
Strong identity controls are therefore becoming central to both cybersecurity and fraud prevention.
What is zero-trust security?
Zero trust is a security approach that avoids assuming that a user or device is safe simply because it is already inside an organisation’s network.
The principle is closer to:
Verify continuously rather than trust automatically.
The Prudential Authority reported in its 2024/25 review of bank cyber resilience that most larger banks were moving toward zero-trust architecture as cloud adoption and remote work made traditional network boundaries less reliable.
Controls can include:
- Strong authentication
- Limited access
- Device checks
- Network segmentation
- Continuous monitoring
If one account is compromised, the aim is to prevent the attacker from automatically reaching everything else.
Why do banks restrict employee access?
An employee generally should not have access to every system simply because they work for the bank.
Access is normally based on what the person needs for their job.
For example, an employee working in marketing probably does not need the same system permissions as a database administrator.
Restricting access reduces the damage that can occur if:
- An account is hacked
- A device is compromised
- An employee acts maliciously
- Credentials are stolen
This idea is often described as least-privilege access.
Are bank employees themselves a cyber risk?
Potentially. Cybersecurity threats can come from outside or inside an organisation.
An insider threat could involve:
- Malicious employees
- Negligent employees
- Stolen employee credentials
- Accidental disclosure
- Unauthorised access
Financial institutions therefore monitor access and separate responsibilities carefully.
Someone capable of creating a payment should not necessarily be the same person who can approve it without oversight.
That principle is both a financial control and a cybersecurity control.
Why are third-party suppliers a major concern?
Banks depend on many outside companies.
These can include:
- Cloud providers
- Software vendors
- Payment processors
- Telecommunications companies
- Data providers
- Cybersecurity firms
- Outsourcing providers
A bank can therefore be affected by a weakness in a company it does not own.
The Prudential Authority has specifically highlighted third-party dependencies as an area requiring stronger cyber resilience and testing.
Cybersecurity is only as strong as some of the systems the institution depends on.
What is a supply-chain cyberattack?
A supply-chain attack targets a supplier that provides technology or services to other organisations.
Instead of attacking 20 banks directly, criminals may find it more efficient to compromise one software supplier used by many institutions.
A compromised software update or third-party connection can then create access to multiple organisations.
This makes vendor risk management a major part of modern banking.
How does cloud computing affect bank cybersecurity?
Cloud services can improve:
- Scalability
- Reliability
- Data processing
- Speed of development
- Disaster recovery
But they can also create risks if poorly managed.
Banks need to think about:
- Data location
- Access controls
- Encryption
- Supplier dependence
- System configuration
- Service outages
- Exit plans
Moving infrastructure to the cloud does not transfer all responsibility to the cloud provider.
The bank still remains responsible for managing its financial and regulatory risks.
What is an API and why does it need protection?
An application programming interface, or API, allows different technology systems to communicate.
Banks use APIs for things such as:
- Payment services
- Mobile apps
- Fintech integrations
- Data exchange
- Open banking
APIs can make financial services faster and more connected.
They can also become an attack surface if authentication, access or data controls are weak.
The Prudential Authority has specifically identified secure API management as important as South African banks expand digital services.
Can a cyberattack stop bank payments?
Potentially. Payment systems depend on technology connecting:
- Banks
- Merchants
- Card networks
- Clearing systems
- Settlement systems
A major outage or cyber incident can therefore disrupt more than the institution directly attacked.
This is one reason regulators care about the resilience of financial-market infrastructure.
Financial stability depends partly on money being able to move reliably.
What does operational resilience mean?
Operational resilience is the ability to keep essential services functioning during serious disruption.
The disruption could come from:
- Cyberattack
- Power failure
- Technology failure
- Supplier outage
- Natural disaster
- Human error
A bank may therefore maintain:
- Backup systems
- Alternative data centres
- Recovery plans
- Crisis teams
- Incident-response procedures
- Offline processes
The objective is not that nothing ever fails.
It is that failure does not become catastrophic.
What happens when a bank suffers a major cyber incident?
The response can involve several teams simultaneously.
The bank may need to:
- Identify what happened.
- Isolate compromised systems.
- Protect customer accounts.
- Preserve evidence.
- Restore critical services.
- Communicate with regulators.
- Notify affected customers where required.
- Investigate the root cause.
- Strengthen controls.
The financial and reputational consequences can continue long after the technical systems are restored.
Do South African financial institutions have to report cyber incidents?
Material incidents are subject to regulatory reporting requirements.
On 1 September 2026, the Prudential Authority and FSCA published Joint Communication 5 of 2026, setting the formal notification template institutions use for material IT and cyber incidents under the existing IT-governance and cybersecurity joint standards.
This shows how cybersecurity has moved into formal financial regulation.
A major incident is not merely something the IT department fixes privately.
Regulators may need to know what happened, how serious it is and how the institution is responding.
Why do regulators care about cyber risk?
A major financial institution is connected to many other parts of the economy.
If one large bank cannot operate, the consequences can affect:
- Customers
- Businesses
- Other banks
- Payment systems
- Investors
- Markets
Cybersecurity can therefore become a systemic concern.
The Prudential Authority supervises banks partly to make sure individual institutions remain safe and sound, but also because failures can spread.
Does cybersecurity affect bank profitability?
Yes. Cybersecurity creates substantial costs.
Banks spend money on:
- Security software
- Fraud systems
- Specialists
- Monitoring
- Cloud security
- Penetration testing
- Incident response
- Backups
- Compliance
- Customer education
But weak security can be even more expensive.
Losses can come from:
- Fraud
- System downtime
- Customer compensation
- Legal claims
- Regulatory consequences
- Incident recovery
- Reputational damage
Cybersecurity is therefore both a cost centre and a form of financial risk management.
Why don’t banks simply make security extremely strict?
Because customers still need usable banking services.
Imagine needing to visit a branch and provide five forms of identification every time you wanted to make a R200 EFT.
That might reduce some fraud, but it would make digital banking almost unusable.
Banks constantly balance:
security versus convenience
Features such as biometric login, device recognition and automated fraud detection are designed partly to increase security without adding excessive friction to every transaction.
Does stronger cybersecurity make banking more expensive?
It creates costs, but technology can also reduce losses and improve efficiency.
A bank that spends more on fraud prevention may avoid much larger losses later.
Security can also become part of the customer proposition.
People are unlikely to keep money with a financial institution they do not trust.
Cybersecurity therefore supports the bank’s broader business model, even when customers cannot see the systems behind it.
How does cybersecurity affect digital banks?
Digital banks can be particularly dependent on cyber resilience because nearly the entire customer relationship happens through technology.
A traditional bank experiencing an app problem may still have branches.
A fully digital bank may have far fewer alternative channels.
That makes reliability and cybersecurity central to the business.
Digital banks may also benefit from newer technology architectures that were designed without decades of legacy systems.
The trade-off is that their services are heavily dependent on digital infrastructure working correctly.
What are legacy banking systems?
Legacy systems are older technology platforms that institutions continue using because they perform important functions.
Banks can have systems built many years ago supporting:
- Accounts
- Payments
- Lending
- Customer records
- Reporting
Replacing them can be complex and risky.
But older systems can be more difficult to maintain and secure.
The Prudential Authority’s 2026 cyber-risk communication specifically warns financial institutions to treat known vulnerabilities in legacy and third-party environments urgently.
What is patching?
Software developers regularly identify and fix security weaknesses.
A patch is an update that corrects a vulnerability or other problem.
If an institution delays installing a critical security patch, attackers can exploit a weakness that is already publicly known.
This is why patch management sounds boring but can be extremely important.
Cybersecurity is not only about futuristic AI attacks.
Basic security discipline still matters.
What is penetration testing?
Penetration testing involves authorised security specialists trying to identify weaknesses before criminals do.
The testers may simulate attacks against:
- Networks
- Applications
- Websites
- APIs
- Employee processes
The aim is not to steal money.
It is to discover vulnerabilities under controlled conditions so they can be fixed.
Banks can also conduct broader cyber exercises simulating serious incidents.
What is ethical hacking?
Ethical hackers use offensive cybersecurity techniques with permission to improve security.
They may work as:
- Penetration testers
- Red-team specialists
- Security consultants
- Vulnerability researchers
Financial institutions employ these skills because understanding how attackers operate can improve defensive systems.
The difference between ethical hacking and criminal hacking is not simply technical skill.
It is authorisation and purpose.
What is a red team?
A red team simulates a real attacker.
Instead of testing only one system, the team may try multiple routes into the organisation.
They might test:
- Technology vulnerabilities
- Employee behaviour
- Physical security
- Credentials
- Network controls
A blue team defends the organisation.
Exercises where both sides interact can reveal gaps that ordinary compliance checks miss.
What does a Security Operations Centre do?
A Security Operations Centre, often called a SOC, monitors systems for suspicious activity.
Security analysts may watch alerts generated by:
- Networks
- Devices
- Applications
- Identity systems
- Cloud environments
When something unusual happens, they investigate.
A good SOC needs to distinguish genuine threats from enormous numbers of routine technical events.
Automation and AI are becoming increasingly useful here because the volume of data can be overwhelming.
What is threat intelligence?
Threat intelligence is information about attackers, vulnerabilities and emerging methods.
Banks may analyse:
- Known criminal groups
- Malware
- Compromised infrastructure
- Stolen credentials
- Attack patterns
- Fraud trends
The objective is to understand what may happen before it reaches the institution.
The Prudential Authority reported that larger South African banks had been strengthening their internal threat-intelligence capabilities to move from reactive defence toward more proactive security.
How does cybersecurity affect fraud teams?
Cybersecurity and fraud prevention increasingly overlap. A cyber team may identify a compromised device.
A fraud team may see suspicious payments coming from it.
An identity team may detect unusual login behaviour.
A credit team may find a fraudulent loan application.
Combining these signals can produce a much stronger defence than treating every department separately.
This creates growing demand for professionals who understand both technology and financial behaviour.
Is cybersecurity the same as financial crime?
No, but the two overlap significantly.
Financial crime is broader and can include:
- Fraud
- Money laundering
- Corruption
- Terrorist financing
- Identity crime
Cybercrime describes crimes carried out using technology or targeting technology.
A phishing attack used to steal bank money can be both cybercrime and financial fraud.
A corrupt cash payment between two people may be financial crime without being cybercrime.
How does cybersecurity affect money laundering controls?
Criminals need somewhere to move stolen money.
Fraud proceeds can pass through:
- Mule accounts
- Newly opened accounts
- Compromised customer accounts
- Crypto services
- Payment platforms
Banks therefore combine cyber and fraud intelligence with anti-money-laundering monitoring.
Stopping the initial attack is one part of the problem.
Following the money afterward is another.
What is a money mule account?
A money mule is someone whose account is used to receive or transfer criminal proceeds.
Some people knowingly participate.
Others are recruited through fake job opportunities, social-media messages or requests to “receive money for someone”.
Once stolen funds enter the account, they may be moved quickly through several other accounts.
That makes rapid detection important.
A bank that identifies suspicious account behaviour quickly may help stop the money before it disappears completely.
Can cybersecurity affect lending?
Yes. Online lending introduces identity and fraud risks.
A criminal may try to:
- Apply using stolen personal information
- Create a synthetic identity
- Take over an existing customer profile
- Manipulate documents
- Redirect disbursements
Credit risk traditionally asks:
Will this borrower repay?
Digital lending adds another question:
Is this applicant even the person they claim to be?
Credit teams and cybersecurity teams therefore increasingly share an interest in identity technology and fraud analytics.
What is synthetic identity fraud?
Synthetic identity fraud combines genuine and false information to create a convincing fake identity.
For example, a criminal might combine:
- A real ID number
- A different person’s contact details
- Fake employment information
- Fabricated documents
AI can make fake documents and profile information more convincing.
Synthetic identities can then be used to open accounts, obtain credit or facilitate other fraud.
How does cybersecurity affect insurance?
Insurers hold sensitive customer and medical information and increasingly sell and service policies digitally.
Cyber risks can affect:
- Policy applications
- Claims
- Customer data
- Payment information
- Adviser systems
- Internal operations
Insurers also have an additional connection to cyber risk through cyber-insurance products sold to businesses.
A serious increase in cyberattacks can therefore affect both an insurer’s own systems and the claims it must pay to customers.
How does cybersecurity affect investment firms?
Asset managers and investment platforms also depend heavily on digital systems.
Potential threats include:
- Account takeover
- Fraudulent withdrawals
- Data theft
- Trading disruption
- Supplier compromise
- Phishing
The amount of money managed can make investment businesses attractive targets.
Cybersecurity therefore extends far beyond ordinary retail banking.
How does cybersecurity affect financial markets?
Financial markets depend on trustworthy and continuously available infrastructure.
A major cyberattack could potentially affect:
- Trading
- Market data
- Clearing
- Settlement
- Broker systems
Even a short outage can create financial consequences when large amounts of money are moving quickly.
Financial-market infrastructure therefore tends to have particularly strict resilience requirements.
What happens to a bank’s reputation after a cyber incident?
Trust can be damaged even if the financial loss is manageable. Banking is built partly on confidence.
Customers expect the institution to:
- Protect their information
- Protect their money
- Keep services available
- Respond quickly to fraud
A poorly handled incident can make customers question all four.
Communication therefore becomes an important part of incident response.
Why do banks sometimes communicate cautiously during cyber incidents?
The institution may still be investigating what happened. Providing incorrect information too early can create additional problems.
At the same time, waiting too long can create uncertainty and speculation.
Banks therefore have to balance:
- Accuracy
- Transparency
- Security
- Regulatory obligations
- Customer needs
A public cyber incident is partly a communications challenge as well as a technical one.
How can customers reduce cyber risk?
Basic habits still make a meaningful difference.
You can reduce risk by:
- Using strong unique passwords
- Protecting your phone
- Keeping software updated
- Avoiding links in unexpected messages
- Never sharing an OTP
- Checking payment requests independently
- Using banking-app security controls
- Reviewing transaction notifications
- Reporting suspicious activity quickly
SABRIC’s fraud guidance repeatedly emphasises that criminals often succeed by manipulating people rather than breaking through bank infrastructure.
A moment of verification can therefore be more valuable than sophisticated technology.
Should you trust a call from your bank?
Do not rely only on what appears on the screen or what the caller knows about you. Caller information can be manipulated, and criminals may already possess some personal details.
If someone asks you to take an urgent financial action, end the call and contact the bank through a trusted number or official app.
A real bank employee should not need your banking password or OTP to “secure” your account.
What should you do if your phone is stolen?
Act quickly once you are safe.
The SABRIC guidance on crimes involving banking apps recommends notifying the bank, mobile network and police as soon as possible after a theft or coercive incident.
Useful steps can include:
- Contacting your bank
- Blocking relevant banking access
- Contacting your mobile network
- Changing important passwords
- Checking recent transactions
- Reporting fraud immediately
Speed matters because criminals can move money rapidly.
Should you keep all your money in your transactional account?
Not necessarily. SABRIC has advised consumers concerned about forced banking-app transfers to consider limiting the money immediately accessible from transactional accounts and using accounts with stronger withdrawal restrictions for larger balances.
This does not eliminate risk, but it can reduce the amount exposed to an immediate transfer.
Banking convenience and financial security sometimes require different account structures.
Can cybersecurity become a finance career?
Yes. Financial institutions employ many professionals whose work sits between finance, technology and risk.
Careers can include:
- Cyber Risk Analyst
- Information Security Analyst
- Technology Risk Analyst
- Fraud Analyst
- Cybersecurity Auditor
- Security Operations Analyst
- Identity and Access Specialist
- IT Risk Manager
- Cyber Resilience Specialist
You do not necessarily need to become a software engineer to work in financial cybersecurity.
Some positions are heavily technical.
Others focus more on:
- Risk
- Controls
- Governance
- Regulation
- Audit
- Business resilience
Is cyber risk a good field for finance graduates?
It can be, particularly if you enjoy technology and risk. A finance or accounting graduate may bring useful knowledge of:
- Banking processes
- Internal controls
- Regulation
- Audit
- Financial risk
You can then develop more technical cybersecurity knowledge.
The reverse also happens.
Someone with a computer science or cybersecurity degree can learn more about banking and financial regulation.
Financial cybersecurity increasingly rewards people who can understand both sides.
Which skills are useful for financial cybersecurity?
The right skills depend on the role. Useful areas can include:
- Cybersecurity fundamentals
- Networking
- Cloud computing
- Identity and access management
- Data analysis
- SQL
- Python
- Risk management
- Banking regulation
- Internal controls
- Incident response
Communication is also important.
A cyber specialist may need to explain a technical vulnerability to executives who do not write code.
Is cybersecurity useful for accountants?
Increasingly, yes. Auditors and accountants work with financial systems rather than only financial statements.
Understanding technology controls can help you evaluate:
- Who can access systems
- Who can approve transactions
- Whether financial data can be altered
- Whether backups exist
- Whether systems are properly controlled
This is why technology risk and IT audit have become important areas inside large accounting and professional-services firms.
Is cybersecurity useful for risk analysts?
Very much so. Cyber risk is increasingly part of enterprise risk management.
A risk analyst may need to consider:
- Probability of cyber incidents
- Financial impact
- Control effectiveness
- Business interruption
- Third-party exposure
- Insurance
- Regulatory consequences
The challenge is translating a technical threat into a business risk that management can understand and manage.
Does cybersecurity pay well?
Specialist cybersecurity skills can command strong salaries, particularly when combined with experience in financial services.
Pay varies significantly between:
- Junior security analysts
- Engineers
- Penetration testers
- Risk specialists
- Security architects
- Senior managers
The strongest earning potential usually appears where technical expertise is combined with responsibility for important systems, teams or regulatory risk.
For finance professionals, cyber risk can also become a route into broader roles such as operational risk, technology risk and senior risk management.
Will cybersecurity become more important in finance?
Almost certainly. Banks are moving further into:
- Mobile banking
- Cloud computing
- APIs
- AI
- Automated lending
- Digital identity
- Real-time payments
Each development creates opportunities but also new risks.
The Prudential Authority’s 2026 focus has already shifted toward AI-accelerated cyber threats, faster attack cycles and stronger operational resilience.
That means cybersecurity is becoming part of ordinary financial management rather than a specialist topic that finance professionals can ignore.
What does cybersecurity mean for the future of banking?
The future bank will probably become more digital, automated and interconnected.
That can make banking:
- Faster
- Cheaper
- More personalised
- Easier to access
But the same connections create more opportunities for attack.
The challenge is therefore not to avoid technology.
It is to make technology safe enough that customers can trust it.
South African regulation now reflects that reality. Financial institutions are expected not only to prevent attacks, but to detect them quickly, contain the damage and recover essential services.
For customers, cybersecurity determines whether digital banking feels safe.
For banks, it affects fraud losses, operating costs, regulation and reputation.
For finance professionals, it is becoming part of how modern financial institutions manage risk.
The line between finance and technology is getting thinner, and cybersecurity sits directly in the middle of it.
