Cyber Crimes / Fraud Risk Management
Fraud vs crime. Threat actors: criminals/competitors/employees (all). Threats: phishing/vishing/malware/ransomware/DDoS. 8 mitigation strategies. Defence in depth. SOC (CISO 24×7). SIEM (detect+analyse+respond). VAPT. Incident response phases.
Banky Fights Cyber Crime! 🔥
Cyber criminals are getting smarter — banks must be smarter! Understanding fraud vs crime, threat actors, attack methods, and defence strategies is crucial for every digital-age banker!
Why Read This Chapter?
Cyber crime is the #1 threat to banking — know the enemy, build the defences
Exam Marks
2-3 questions — threat actor = all (criminals/competitors/employees — exam PYQ!), SIEM for detecting/analysing/responding (exam PYQ!), patching OS for known vulnerabilities (exam PYQ!), VAPT for all (network/server/system — exam PYQ!), C-SOC ≠ forensic investigation (exam PYQ!). Important!
Career Growth
Every banker is a first line of defence — recognising and reporting cyber threats is a core responsibility
Real Life
Knowing how cyber criminals operate helps you protect your personal banking and data

Key Definitions — Banky Asks, Mentor Explains
Every term explained like you’re 10
Banky’s Understanding: Threat actors (exam PYQ! = ALL): (1) Cybercriminals (individuals/groups for financial gain). (2) Business competitors (for competitive advantage). (3) Current or former employees (accidental or intentional). Cyber threats: Identity theft, data breach, hacking, malware, viruses, ransomware (encrypts data for ransom), phishing (email), vishing (voice), smishing (SMS), pharming (redirect to fake site), DDoS (flood with traffic to shut down), cyber squatting/bullying/warfare. Risks from attacks: Financial loss, data loss, productivity loss, investigation cost, customer compensation, reputational damage, regulatory penalties.
Banky’s Understanding: SIEM: Security Information and Event Management. Detects, analyses, and responds to security threats (exam PYQ! — not firewall, not IDS, not IPS). Combines SIM+SEM. Real-time analysis of security alerts. Data consolidation from multiple points. Custom dashboards. Integration with other products. SOC: Security Operations Centre. CISO-led (Chief Information Security Officer). 24×7 monitoring. Security analysts+engineers. Monitors: networks, servers, endpoints, databases, applications, websites. Detect→analyse→respond→report. C-SOC: Cyber SOC per RBI. Board briefing, dashboards, policy metrics, incident investigation, dynamic behaviour analysis (IoC), analytics, counter response, honeypot. NOT for forensic investigation of financial frauds (exam PYQ!).
Banky’s Understanding: 8 essential mitigation strategies: (1) Application whitelisting (only approved software runs). (2) Patching applications (fix known vulnerabilities). (3) Configuring macro settings (block untrusted macros). (4) Application hardening (remove unnecessary features). (5) Restricting admin privileges (limit powerful access). (6) Patching operating systems — for known security vulnerabilities (exam PYQ! — not unknown macros/DDoS). (7) Multifactor authentication (multiple verification layers). (8) Daily backups (ensure data availability). Defence in depth: Multiple layers of security controls throughout the network. No single point of failure. Increases time+complexity for attackers. Redundancy — if one layer fails, others protect. Layers: perimeter firewall → network security → host security → application security → data security.
Banky’s Understanding: VAPT: Vulnerability Assessment and Penetration Testing. Identifies vulnerabilities in network, server, AND system infrastructure = ALL (exam PYQ!). VA = internal assessment (what is vulnerable). PT = external testing (simulated attack). Periodical exercises through approved third-party vendors. Classified: High/Medium/Low risk. Mandatory to mitigate and report to top management. Incident Response Phases: Proactive: (1) Preparation and prevention. (2) Incident identification/detection. (3) Analysis. Responsive: (4) Containment. (5) Cleansing and eradication. (6) Recovery. Follow-up: (7) Lessons learned, process improvement. Banks tools: SIEM, firewalls, IDS/IPS, anti-APT, anti-DDoS, anti-phishing, malware monitoring, PIM, FIM, WAF, cyber insurance, VAPT, awareness training.
Chapter Explained in Simple Stories
So easy even Banky’s nephew understands
🔥 Block 1: Threats, SIEM & SOC
Threat actors: Criminals + competitors + employees = ALL (exam PYQ!).
Threats: Phishing/vishing/smishing/malware/ransomware/DDoS/identity theft/data breach.
SIEM: Detect + analyse + respond to threats (exam PYQ! — not firewall/IDS/IPS!).
SOC: CISO-led 24×7. C-SOC per RBI. C-SOC ≠ forensic investigation of financial frauds (exam PYQ!).
🛡️ Block 2: 8 Strategies, Defence in Depth & VAPT
8 strategies: Whitelisting, patching apps, macros, hardening, admin restrict, patching OS (known vulnerabilities — exam PYQ!), MFA, daily backups.
Defence in depth: Multiple layers, no single point of failure.
VAPT: Vulnerabilities in network + server + system = ALL (exam PYQ!).
Incident Response: Prepare → detect → analyse → contain → eradicate → recover → follow-up.

✅ Must-Know Facts — Highest Probability
- Threat actor = cybercriminal + competitor + current/former employee = ALL — exam PYQ!
- SIEM = detecting, analysing, responding to security threats (not firewall/IDS/IPS) — exam PYQ!
- Patching OS = remediate known security vulnerabilities — exam PYQ!
- VAPT identifies vulnerabilities in network + server + system infrastructure = ALL — exam PYQ!
- C-SOC requirement does NOT include forensic investigation of financial frauds — exam PYQ!
- 8 mitigation: whitelisting, patching apps, macros, hardening, admin, patching OS, MFA, backups
- Defence in depth: multiple layers, no single point of failure, increases attacker complexity
- SOC: CISO-led, 24×7, security analysts, monitors all systems
- Fraud = deception for financial gain | Cybercrime = criminal act using computers/networks
- Incident response: preparation → detection → containment → eradication → recovery → follow-up
- RBI Cyber Security Framework (June 2016) + Digital Payment Security Controls (Feb 2021)
- CERT-In = nodal agency for cyber security under IT Act
- Honeypot = decoy system to attract and study attackers (part of C-SOC)
- VA = internal assessment | PT = external simulated attack | Both together = VAPT
