Cybersecurity Interview Questions for Indian Companies 2026

Cybersecurity in India spans significantly different roles: prepare for the right one.

SOC Analyst (Security Operations Centre): monitor alerts from SIEM tools (Splunk, IBM QRadar, Microsoft Sentinel), investigate incidents, escalate when needed. Entry-level friendly. Starting salary: ₹5–12 LPA. Penetration Tester / Ethical Hacker: actively probe systems for vulnerabilities using tools like Metasploit, Burp Suite, Nmap. CEH or OSCP certification expected. Starting salary: ₹8–20 LPA. Cloud Security Engineer: secure AWS/Azure/GCP environments: IAM policies, security groups, encryption key management, CSPM (Cloud Security Posture Management). Starting salary: ₹14–30 LPA. GRC Analyst: Governance, Risk, and Compliance: ISO 27001, SOC 2, India's DPDP Act, RBI guidelines. Less technical, more process-oriented. Starting salary: ₹6–15 LPA. Application Security Engineer: code review for security vulnerabilities (OWASP Top 10), SAST/DAST tooling, secure SDLC. Starting salary: ₹14–28 LPA.

These fundamentals appear across all cybersecurity roles in India.

CIA Triad: Confidentiality (only authorised access), Integrity (data has not been tampered with), Availability (systems remain operational). Every security decision is a trade-off between these three. Authentication vs Authorisation: authentication is 'who are you?' (identity verification); authorisation is 'what are you allowed to do?' (access control). Common question: 'A user logs in successfully but cannot access a file: is that an authentication or authorisation problem?': authorisation. Common attack types: SQL injection (malicious SQL in input fields), XSS (injecting JavaScript into web pages), CSRF (tricking users into making unintended requests), phishing (social engineering to steal credentials), ransomware (encrypting files and demanding payment). OWASP Top 10: know all 10: especially A01 Broken Access Control, A03 Injection, A07 Identification and Authentication Failures.

Network security is tested in SOC analyst and penetration testing interviews.

Firewall types: packet filtering (examines headers only), stateful inspection (tracks connection state), next-gen firewalls (DPI: deep packet inspection, application awareness). IDS vs IPS: Intrusion Detection System only alerts; Intrusion Prevention System actively blocks. VPN types: site-to-site (connects office networks), client-to-site (remote employee access), split tunnelling (only corporate traffic goes through VPN). Common question: 'What happens in a man-in-the-middle attack and how does HTTPS prevent it?': MITM intercepts communication; HTTPS uses TLS with certificate validation so clients can verify server identity. Port scanning: common ports to know: 22 (SSH), 80 (HTTP), 443 (HTTPS), 3306 (MySQL), 5432 (PostgreSQL), 27017 (MongoDB), 3389 (RDP: Windows remote desktop).

SOC analyst interviews heavily test SIEM tools and incident response processes.

SIEM (Security Information and Event Management): collects logs from across the environment (firewalls, endpoints, cloud, applications), correlates them to detect patterns, and fires alerts. Tools: Splunk (most common in India), Microsoft Sentinel (Azure-native), IBM QRadar, Elastic SIEM. Log analysis: what to look for: failed login attempts (brute force), unusual outbound connections (data exfiltration), process execution from unusual locations (malware). MITRE ATT&CK framework: maps attacker tactics and techniques: SOC analysts use it to categorise incidents and identify gaps in detection coverage. Incident response phases: Preparation → Identification → Containment → Eradication → Recovery → Lessons Learned (PICERL). Common question: 'A user reports their laptop is running slowly and a new process they don't recognise is running: walk me through your incident response.'

Certifications carry more weight in cybersecurity than in most other IT fields in India.

Entry-level: CompTIA Security+: widely recognised, covers security fundamentals, ideal for SOC analyst roles. CEH (Certified Ethical Hacker): valued in India for penetration testing roles, though OSCP is considered the gold standard for technical depth. OSCP (Offensive Security Certified Professional): the most respected penetration testing certification globally: hands-on, lab-based exam. Very hard to pass; significant salary premium for those who hold it. For cloud security: AWS Security Specialty or Azure Security Engineer (AZ-500). For GRC: CISA (Certified Information Systems Auditor), ISO 27001 Lead Implementer, or CRISC. Salary impact of certifications: OSCP holders earn 30–50% more than non-certified pentesters in India.
