01
How would you use Sysmon to improve endpoint visibility on Windows?
Sysmon is a free Microsoft Sysinternals tool that logs detailed endpoint events to the Windows event log. Useful events are ID 1 process creation with hashes and command line, ID 3 network connection, ID 11 file creation, ID 13 registry changes and ID 22 DNS queries. With a tuned configuration, it gives rich telemetry for SIEM detections when a full EDR is not available or as an extra source.
02
Which cloud logs are essential for security monitoring?
Essential sources are control plane audit logs such as AWS CloudTrail, Azure Activity Log and Entra sign-in logs, and Google Cloud Audit Logs. Add network flow logs, DNS logs, load balancer and WAF logs, storage access logs for sensitive buckets, and Kubernetes audit logs. Send them to a central account or SIEM that workload owners cannot delete, and enable threat detection services like GuardDuty.
Check supported protocol versions, ciphers and certificate details. OpenSSL gives a quick view, and tools like testssl.sh give a full report.
openssl s_client -connect example.com:443 -tls1_2
openssl s_client -connect example.com:443 -servername example.com | openssl x509 -noout -dates -issuer
./testssl.sh example.com
Disable TLS 1.0 and 1.1, weak ciphers like RC4 and 3DES, and fix expiring certificates.
04
What is the shared responsibility model in cloud security?
The cloud provider secures the infrastructure: data centres, hardware, hypervisors and managed service internals. The customer secures what they put in the cloud: identities, data, configurations, network rules and their applications. The split changes by service type; with IaaS you patch the OS, with SaaS you mainly manage users and data settings. Most cloud breaches come from customer-side misconfiguration, not provider failures.
05
How do you handle a network team that refuses a security change you recommended?
Situation: the network team rejected my request to block outbound SMB at the firewall, fearing outages. Task: reduce the risk without damaging the relationship. Action: I shared flow data showing only two servers needed it, proposed an allowlist for them and a one-week monitor-only phase. Result: the team agreed, the rule went live with zero incidents, and we now review rules together monthly.
06
A TLS certificate expired on the main customer portal and caused an outage. How do you prevent this in future?
First renew and deploy the certificate to restore service. For prevention, build a certificate inventory from scanning and CT logs, automate issuance and renewal with ACME where possible, and set alerts at 30, 14 and 7 days before expiry to a team mailbox, not an individual. Assign an owner per certificate and add expiry checks to monitoring dashboards, since shorter lifetimes are coming.
07
What is the difference between authentication, authorisation and accounting?
Authentication proves who you are, for example password plus an OTP or passkey. Authorisation decides what you are allowed to do after login, such as read-only access to a finance folder. Accounting, or auditing, records what you actually did, like logins, file access and admin changes. Together they are called AAA. Weak accounting is a common gap, because without logs an incident cannot be investigated.
Start from business needs and regulations, keep it short and clear, and state scope, purpose, roles, requirements and exceptions. Avoid technical detail that changes often; put that in standards. Get input from IT, HR and legal, then management approval. Publish it where staff can find it, train people, require acknowledgement and review it at least yearly or after major changes.
09
How would you run a data protection impact assessment under the DPDP Act?
Describe the processing: what personal data, purpose, legal basis, data flows, storage, retention and vendors. Assess risks to individuals, such as unauthorised access or excessive collection, and evaluate safeguards like encryption, access control and minimisation. Recommend changes, get sign-off from the data protection officer or privacy lead, and review it when processing changes. Significant data fiduciaries must perform periodic DPIAs and audits.
In BEC, attackers take over or impersonate an executive, vendor or finance mailbox to trick staff into making payments or changing bank details. It often uses no malware, just a compromised account, mailbox forwarding rules and convincing requests. Controls include MFA, DMARC enforcement, alerts on new inbox rules, and a mandatory call-back process on a known number for any change to payment details.
A Distributed Denial of Service attack floods a target from many sources to exhaust bandwidth, connection tables or application resources. Types are volumetric floods, protocol attacks like SYN floods, and application layer floods hitting costly pages. Mitigation uses upstream scrubbing services or CDN providers, anycast networks, rate limiting, SYN cookies, autoscaling, and a tested runbook agreed with the ISP before an attack.
12
How do you collect basic triage data from a suspected compromised Windows host?
Collect volatile data first, ideally with EDR live response or a trusted triage tool. Useful built-in commands:
tasklist /v
netstat -ano
schtasks /query /fo LIST /v
wmic service get name,pathname,startmode
reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Run
wevtutil epl Security C:\IR\security.evtx
Save output to external media and hash every file.
13
How would you design a joiner, mover, leaver process for a growing company?
JML is the identity lifecycle. Joiners get accounts and baseline access from HR data on day one. Movers change roles, and their old access must be removed, not just new access added, to avoid privilege creep. Leavers must be disabled promptly, ideally automatically when HR records their exit. Automating JML from the HR system to the identity platform reduces orphan accounts, which auditors frequently flag.
Passkeys are FIDO2 credentials that replace passwords. The device creates a key pair per website; the private key stays in the device or synced password manager, protected by biometrics or PIN, and the server stores only the public key. Login is a signature over a challenge tied to the real domain, so passkeys resist phishing and cannot be reused across sites. They also remove password reset load.
For sharing, use the recipient's public key; for personal storage, use symmetric mode with a strong passphrase.
gpg --encrypt --recipient analyst@example.in report.pdf
gpg --output report.pdf --decrypt report.pdf.gpg
gpg --symmetric --cipher-algo AES256 backup.tar
Verify the recipient key fingerprint out of band before trusting it.
16
Your SOC sees heavy DNS traffic with long random subdomains from one workstation. Which DNS attacks should you consider and what defences apply?
Key DNS attacks are cache poisoning, which inserts false records; DNS tunnelling, which hides data or command traffic inside queries; domain hijacking through registrar account takeover; and DNS amplification DDoS. Defences include DNSSEC to sign records, protective DNS resolvers that block malicious domains, monitoring for long or high-entropy subdomains, registrar lock with MFA, and rate limiting open resolvers.
17
How do you analyse a memory dump with Volatility 3?
Run plugins to list processes, network connections and injected code, then dig into suspicious items.
vol -f mem.raw windows.info
vol -f mem.raw windows.pstree
vol -f mem.raw windows.netscan
vol -f mem.raw windows.cmdline
vol -f mem.raw windows.malfind
Look for unusual parent-child processes, processes in odd paths and connections to unknown IPs.
18
You receive an alert for 300 failed logins on one account followed by a success. How do you triage it?
This pattern suggests brute force or password spraying that succeeded. Check source IPs, location and logon type, and whether MFA was used for the success. Review what the account did after login, such as mailbox rules, file access or new tokens. If suspicious, disable the account or revoke sessions, reset the password, block source IPs and check whether the same IPs targeted other accounts.
Conditional access applies policies based on signals at sign-in, such as user, group, device compliance, location, application and risk score. For example, allow finance apps only from managed devices with MFA, block legacy authentication, and require a password change when sign-in risk is high. It is a key Zero Trust building block in platforms like Microsoft Entra ID. Policies need testing in report-only mode first.
20
How do you find overly permissive security groups with the AWS CLI?
Query security groups that allow ingress from anywhere, then review each.
aws ec2 describe-security-groups \
--filters Name=ip-permission.cidr,Values=0.0.0.0/0 \
--query 'SecurityGroups[*].[GroupId,GroupName]' --output table
Pay attention to ports 22, 3389, 3306 and 5432. Replace them with VPN, bastion or session manager access.
21
Tell me about a time you improved a process with automation.
Situation: our team checked cloud accounts manually every week for public buckets, which took hours. Task: make it faster and continuous. Action: I wrote a small script using the cloud CLI, scheduled it, and sent findings to a team channel with owner tags, then moved it into the CSPM tool. Result: checks ran hourly and average exposure time dropped from days to under an hour.
NIST CSF 2.0, released in 2024, organises cyber security outcomes into six functions: Govern, Identify, Protect, Detect, Respond and Recover. Govern was added to cover strategy, roles, policy and supply chain risk. Each function has categories and subcategories. Organisations create current and target profiles to find gaps and plan improvements. It is voluntary and widely used to report maturity to boards.
23
How do you design an access review for a critical application?
Define scope, such as all users with write or admin rights. Pull entitlements and last-login data from the app, and route each item to the user's manager and the app owner. Give clear choices of keep or revoke with a deadline, and revoke automatically if not reviewed. Capture evidence for auditors, and review exceptions with security. Run it quarterly for privileged access.
24
What is business continuity and disaster recovery, and what are RTO and RPO?
Business continuity keeps critical business functions running during disruption, while disaster recovery restores IT systems. Recovery Time Objective is the maximum acceptable downtime, and Recovery Point Objective is the maximum acceptable data loss measured in time. A payments system may need an RTO of one hour and an RPO near zero, which needs replication, while an internal wiki may accept a day.
25
Tell me about a time you learned a difficult technical topic quickly.
Situation: in my final year project I needed TLS mutual authentication for an IoT prototype within two weeks. Task: understand PKI enough to build it. Action: I read the TLS 1.3 overview, set up a small CA with OpenSSL, issued device certificates and tested failures deliberately. Result: the demo worked, and I documented the steps so classmates could reuse them, which helped our team score well.
The Payment Card Industry Data Security Standard applies to any organisation that stores, processes or transmits cardholder data. Version 4.0.1 is current, and its future-dated requirements became mandatory from March 2025. It has 12 requirement areas, including network security controls, protecting stored data, encryption in transit, vulnerability management, access control, logging and testing. Reducing scope through tokenisation and segmentation lowers compliance effort.
Threat hunting is proactive searching for attackers who evaded existing detections. Hunters start from a hypothesis, for example that attackers use scheduled tasks for persistence, then query EDR and SIEM data to confirm or reject it. Findings become new detection rules. Hunting requires good data retention, knowledge of normal behaviour and frameworks like MITRE ATT&CK to guide hypotheses.
28
What is network segmentation and why is it important?
Segmentation splits a network into zones such as user, server, OT, guest and management, with controlled traffic between them using VLANs, firewalls and ACLs. It limits lateral movement, so ransomware on one laptop cannot reach every server. It also reduces compliance scope, for example isolating the cardholder data environment for PCI DSS. Micro-segmentation goes further with per-workload policies in data centres and cloud.
A SOC is the team, processes and technology that monitor an organisation's environment around the clock, detect threats, triage alerts and coordinate response. Tier 1 analysts triage alerts, Tier 2 investigate and contain, and Tier 3 or threat hunters handle complex cases and build detections. A SOC can be in-house, outsourced to an MSSP or hybrid. Many Indian IT firms run global SOCs for international clients.
30
Management wants to replace the VPN with Zero Trust access. How would you plan it?
I would start by inventorying applications and who uses them, then pick a low-risk app group for a pilot with an identity-aware proxy or ZTNA service. Integrate it with the identity provider, enforce MFA and device posture checks, and monitor access logs. Expand app by app, keep the VPN for legacy needs during transition, and retire it once every app is covered and tested.
Zero Trust removes implicit trust based on network location. Every request is verified using identity, device health and context, access is least privilege and granted per session, and the environment is assumed to be already breached. NIST SP 800-207 describes the model. In practice it means strong MFA, device posture checks, identity-aware proxies instead of flat VPN access, micro-segmentation and continuous monitoring. It is a journey, not a single product.
32
How do you write basic Linux host firewall rules with nftables?
An Intrusion Detection System monitors traffic or hosts and raises alerts but does not block. An Intrusion Prevention System sits inline and can drop malicious packets in real time. IDS is safer for tuning because false positives do not break traffic, while IPS gives active protection. Detection can be signature based, as in Snort and Suricata rules, or anomaly based using baselines of normal behaviour.
34
How would you implement just-in-time privileged access in the cloud?
Remove standing admin roles. Make users eligible for roles through a PIM or PAM tool, so they request activation with justification, MFA and optional approval, for a limited time like two hours. Log every activation and alert on unusual ones. For automation, use workload identities with narrow roles instead of admin keys. Review eligible assignments quarterly to keep the list small.
TPRM assesses and monitors the security of vendors that access your data or systems, since many breaches start with a supplier. It includes tiering vendors by risk, security questionnaires, reviewing SOC 2 or ISO 27001 reports, contract clauses for breach notification and audit rights, and continuous monitoring. High-risk vendors such as payroll or cloud providers get deeper reviews and annual reassessment.
36
What is the difference between OAuth 2.0 and OpenID Connect?
OAuth 2.0 is an authorisation framework; it lets an app get an access token to call an API on a user's behalf, without the user's password. It does not define who the user is. OpenID Connect adds an identity layer with an ID token, a signed JWT containing user claims, and a userinfo endpoint. Use OIDC for login, and OAuth access tokens for API authorisation.
