Why Indian Banks Need Breach and Attack Simulation: Beyond Checkbox Compliance

Indian banks spend crores on cybersecurity — firewalls, SIEM, endpoint protection, SOC operations. But how do you know any of it actually works? When a real attacker targets your bank with a sophisticated phishing campaign, lateral movement through your network, and data exfiltration from your core banking system, will your controls detect it? Will your SOC respond in time? Will your SIEM generate the right alerts?

Most banks cannot answer these questions honestly. That is exactly the problem Breach and Attack Simulation (BAS) solves.

What Is Breach and Attack Simulation

Breach and Attack Simulation is the automated, continuous testing of your security controls against real-world attack techniques. Unlike traditional penetration testing — which is manual, expensive, and happens once or twice a year — BAS runs simulated attacks against your actual production environment on a regular schedule.

A BAS platform deploys a lightweight agent on your network that executes attack techniques from the MITRE ATT&CK framework — the same techniques used by real threat actors targeting the financial sector. It tests whether your SIEM detects the activity, whether your firewall blocks the traffic, and whether your SOC team receives actionable alerts.

The output is a detailed report showing:

• Which attack techniques were detected by your security stack
• Which were blocked before causing impact
• Which bypassed all controls entirely — the gaps that a real attacker would exploit

RBI Mandates Red Team Exercises — BAS Delivers Them at Scale

The RBI cybersecurity framework explicitly requires "periodic red team or adversary simulation exercises." Traditional red team engagements involve hiring external experts to manually attempt to breach your systems. This is valuable but has significant limitations:

• Cost: A single red team engagement costs ₹15-50 lakhs depending on scope
• Frequency: Budgets typically allow only annual or semi-annual exercises
• Coverage: Manual red teams can only test a subset of attack techniques in their engagement window
• Point-in-time: Results are valid for the moment they were tested — your environment changes daily

BAS addresses every one of these limitations. It runs continuously or on a scheduled basis, tests hundreds of attack techniques per simulation, costs a fraction of manual red teaming, and provides always-current results. This does not replace human red teams entirely — it supplements them with continuous automated validation between manual engagements.

What BAS Reveals That Audits Miss

Compliance audits check whether controls exist. BAS checks whether controls work. The difference is critical. We consistently see banks that pass audits but fail simulations:

• SIEM rules that never fire: Detection rules written years ago for threats that have evolved. The rule exists (audit pass) but does not detect the current technique (BAS fail).
• Firewall policies with shadow rules: Conflicting rules that allow traffic the security team believes is blocked. Configuration audit says "firewall present" (audit pass), but BAS shows lateral movement succeeds (BAS fail).
• SOC alert fatigue: Thousands of daily alerts cause analysts to miss the critical ones. SLA metrics show "alerts reviewed" (audit pass), but actual attack detection rate is under 40% (BAS fail).
• Endpoint protection gaps: EDR deployed on servers but not on developer workstations, ATMs, or branch systems. Asset inventory shows "EDR deployed" (audit pass), but BAS finds unprotected attack paths (BAS fail).

MITRE ATT&CK Mapping for Banking Threat Actors

The most sophisticated BAS platforms map their simulations to the MITRE ATT&CK framework, which catalogues real-world attack techniques observed in actual incidents. For the Indian banking sector, the most relevant threat actor profiles include:

• FIN groups: Financially motivated groups targeting SWIFT systems, ATM networks, and payment processing infrastructure
• State-sponsored APTs: Advanced persistent threats targeting banking data for intelligence collection
• Ransomware operators: Groups like LockBit and BlackCat that increasingly target Indian financial institutions
• Insider threats: Simulating privileged account misuse and data exfiltration by insiders

A good BAS platform lets you select these adversary profiles and run their exact techniques against your environment. You get a MITRE ATT&CK heatmap showing your coverage — green for detected, red for missed — which becomes the basis for focused security improvement.

Getting Started with BAS

Implementing BAS in a banking environment requires:

• Agent deployment: A lightweight agent installed on a test system within your network. No changes to your production infrastructure required.
• Adversary profile selection: Choose from pre-built profiles mapped to banking-specific threat actors
• Simulation execution: Run safe, controlled simulations that test detection without causing actual impact
• Results analysis: Review the ATT&CK heatmap, identify gaps, and prioritise remediation
• Continuous validation: Schedule regular simulations to ensure new deployments and configuration changes do not create new gaps

Ogma's Breach and Attack Simulation platform is powered by MITRE Caldera with 29 adversary profiles and full ATT&CK mapping. Banks can deploy in under 15 minutes, run their first simulation immediately, and receive a comprehensive report. With self-service access, no per-engagement fees, and continuous scheduling, it is the most cost-effective way for Indian banks to satisfy RBI's red team requirements while building genuine cyber resilience.
