Chapter 15: Security Operations, Governance & Compliance
Security Operations, Governance & Compliance — the final “glue” chapter that ties everything together into how real organizations actually run security day-to-day, stay legal, and survive audits and board meetings.
This is the chapter that turns you from a technical person into someone who can talk to executives, CISOs, auditors, and regulators. In January 2026 (right here in Airoli at around 4 PM IST, with the Navi Mumbai sky turning that beautiful orange), this stuff is mission-critical in India:
- DPDP Act rules are rolling out hard (significant data fiduciaries already under audit pressure).
- CERT-In incident reporting is stricter than ever (within 6 hours for critical infra).
- RBI, SEBI, IRDAI, MeitY all have overlapping cyber mandates.
- Most mid-size and large Indian companies now run 24/7 SOCs or outsource to MSSPs (Quick Heal, K7, Palo Alto Cortex XDR partners).
We’ll go deep on each topic, with real Indian examples, analogies, and practical 2026 realities.
1. Security Frameworks (NIST CSF, ISO 27001, CIS Controls)
These are structured blueprints organizations use to build, measure, and improve security programs.
- NIST Cybersecurity Framework (CSF 2.0 – released 2024, widely adopted 2026) Voluntary, flexible, function-based: Govern, Identify, Protect, Detect, Respond, Recover. Govern is the big 2024 addition (leadership, policies, oversight). Why popular in India: Free, aligns with CERT-In guidelines, easy to map to DPDP/RBI requirements. Example: A Mumbai fintech maps its program → “Govern: CISO reports to board quarterly”, “Protect: MFA everywhere”, “Detect: SIEM + EDR”, “Respond: IR playbook tested biannually”.
- ISO 27001:2022 (current version) Certifiable international standard (management system). Annex A controls (93 in 2022 version) cover org, people, physical, tech. India reality: Many enterprises (TCS, Infosys, banks) are ISO 27001 certified → mandatory for some clients/gov contracts. Process: Scope → risk assessment → Statement of Applicability → implement controls → internal audit → certification body audit. Example: Navi Mumbai IT services firm gets ISO 27001 → proves to European clients they meet GDPR-like standards → wins contract.
- CIS Controls v8 (2021, still dominant in 2026) 18 prioritized safeguards (Implementation Groups 1–3: basic → advanced). Very practical — “do these first” list (inventory assets, secure configs, data protection, etc.). India use: Startups & mid-size orgs start with IG1 (basic hygiene), then IG2/3. Example: Small Airoli SaaS company implements CIS IG1 → asset inventory + MFA + backups → survives first phishing wave without major loss.
Quick comparison (2026 lens):
| Framework | Type | Certifiable? | Best For | India Adoption 2026 |
|---|---|---|---|---|
| NIST CSF | Framework (functions) | No | Flexible, gov-aligned, free | Very High |
| ISO 27001 | Management system | Yes | International clients, compliance | High (enterprises) |
| CIS Controls | Prioritized actions | No | Quick wins, startups/mid-size | High (practical) |
Many orgs use all three: NIST for strategy, CIS for tactical actions, ISO for certification.
2. Security Policies, Procedures, Awareness Training
Policies = High-level “what we do” statements (approved by board/CISO). Procedures = Step-by-step “how we do it” guides. Awareness = Making employees not the weakest link.
Key policies (2026 India must-haves):
- Information Security Policy
- Acceptable Use Policy
- Data Classification & Handling
- Incident Response Policy
- Remote Access / BYOD Policy
- Password / MFA Policy
- Third-Party Risk Management
Procedures examples:
- “How to report phishing” flowchart
- “Password reset process” (with MFA re-enroll)
- “Backup & restore procedure” (who, when, test frequency)
Security Awareness Training (huge in 2026):
- Mandatory quarterly (at least annual).
- Phishing simulations (KnowBe4, Proofpoint, Microsoft Attack Simulator).
- Role-based (finance team gets deepfake training).
- India-specific: UPI fraud, Aadhaar scams, “digital arrest” awareness.
Example: Mid-size Pune manufacturing firm → monthly 10-min video + quiz → phishing sim every quarter → click rate drops from 28% to 4% in one year.
3. Risk Assessment & Business Impact Analysis
Risk Assessment = Identify → Analyze → Evaluate risks (threat × vuln × impact).
Types:
- Qualitative (High/Medium/Low)
- Quantitative (₹ loss, downtime hours)
Business Impact Analysis (BIA) = Part of risk assessment. Asks: “If this asset/process fails, how bad?” Outputs: RTO (Recovery Time Objective), RPO (Recovery Point Objective), criticality ranking.
2026 India process (common in banks/IT):
- Asset inventory (apps, data, servers, people).
- Threat scenarios (ransomware, insider, supply-chain).
- Vulnerability scanning + threat intel.
- Impact scoring (financial, reputational, regulatory, safety).
- Prioritize high risks → treat (mitigate, accept, transfer, avoid).
Example: Hospital BIA → “Patient monitoring system down 4 hours = life risk → RTO 1 hour, RPO 5 min → needs redundant setup + offline backups”.
4. Compliance Basics (PCI-DSS, HIPAA, SOC 2)
- PCI-DSS v4.0 (current 2026) Payment card security (applies to anyone handling cards/UPI linked to cards). 12 requirements (build secure network, protect data, vuln management, access control, monitoring, policy). India: Mandatory for banks, payment gateways, merchants. RBI aligns with it. Example: UPI app must encrypt card data in transit/rest, tokenization, annual pentest.
- HIPAA (US, but relevant for Indian firms serving US healthcare) Protects PHI (Protected Health Information). Administrative, physical, technical safeguards. Example: Indian BPO handling US hospital data → must sign BAA, encrypt PHI, log access.
- SOC 2 (AICPA) Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality, Privacy. Type 1 (design), Type 2 (operating effectiveness over time). India 2026: Most SaaS companies get SOC 2 Type 2 → required by US/EU clients. Example: Airoli cloud startup gets SOC 2 → proves controls work → wins big enterprise deal.
5. Blue Team Operations and SOC Roles
Blue Team = Defenders (vs Red Team attackers).
SOC (Security Operations Center) — 24/7 monitoring & response hub.
Typical 2026 SOC roles (India – Tier 1/2/3 model):
- Tier 1 Analyst (L1): Alert triage, basic investigation, escalate (Splunk/Sentinel/QRadar).
- Tier 2 Analyst (L2): Deep-dive, malware analysis, containment (EDR, Wireshark).
- Tier 3 / Threat Hunter: Proactive hunting, reverse engineering, threat intel.
- SOC Manager / Incident Lead: Coordination, reporting, playbooks.
- DFIR Specialist (sometimes separate): Forensics, breach recovery.
Operations (daily life):
- Shift handovers, alert queues.
- Threat intel feeds (CERT-In, FS-ISAC, STIX/TAXII).
- SOAR automation (playbooks auto-run for common alerts).
- Monthly red-team / purple-team exercises.
Example (real Indian SOC): Alert → “multiple failed logins + PowerShell download” → L1 escalates → L2 confirms credential theft → L3 hunts for lateral movement → containment (disable account, isolate host) → report to CERT-In.
Takeaway: SOC is heartbeat of security ops—good one prevents small incidents becoming headlines.
