3 QUESTIONS FREESign up to unlock the full question bank and track your progress.Unlock every question and answer, then continue practising company-wise and package-wise.
Start with admins and remote access, then high-risk groups like finance. Pick methods, preferring authenticator app number matching and passkeys or FIDO2 keys for admins. Pilot with one department, prepare helpdesk scripts and self-service registration, and communicate clearly with deadlines. Use conditional access in report-only mode to find gaps, then enforce. Block legacy authentication and track registration rates weekly.
02
A user on the office LAN reports repeated certificate warnings and you suspect ARP spoofing. What is happening and how do you stop it?
ARP has no authentication, so an attacker on the same LAN can send fake ARP replies linking their MAC address to the gateway's IP. Victims then send traffic through the attacker, enabling man-in-the-middle interception. Defences include Dynamic ARP Inspection with DHCP snooping on switches, port security, network access control, and encrypting traffic end to end with TLS so intercepted data is useless.
Important metrics are mean time to detect, mean time to respond, alert volume per analyst, false positive rate per rule, percentage of alerts closed within SLA, detection coverage against priority ATT&CK techniques and log source health. Metrics should drive improvement, not punish analysts. For example, a rule with 95 percent false positives should be tuned, and long response times may point to missing automation.
04
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.
Detection engineering treats detections like software: rules are written from threat models and ATT&CK techniques, stored in version control, tested with attack simulations, peer reviewed and measured for false positive rate. Formats like Sigma let rules be shared across SIEMs. Teams track coverage, tune noisy rules and retire obsolete ones. This replaces ad hoc rule creation that leads to noisy, untested alerts.
Forward secrecy means that if a server's long-term private key is stolen later, previously recorded sessions still cannot be decrypted. It is achieved with ephemeral key exchange, such as ECDHE, where a new key pair is created for each session and discarded. TLS 1.3 makes forward secrecy mandatory by removing static RSA key exchange, which is one reason older TLS configurations are considered weak.
07
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.
08
A user's account shows sign-in risk high in your identity platform. What do you do?
Review the details: unfamiliar location, anonymous IP, leaked credentials or impossible travel. Check what happened after sign-in, such as MFA method registration, mailbox rules or data downloads. If compromise is likely, revoke sessions, reset the password, remove unknown MFA methods and contact the user out of band. Then confirm policies require MFA or block high-risk sign-ins automatically.
IaC scanning checks Terraform, CloudFormation, Bicep or Kubernetes manifests for misconfigurations before deployment, such as public buckets or unencrypted databases. Tools include Checkov, tfsec in Trivy, and KICS. It shifts security left, so issues are fixed in a pull request rather than in production. Combine it with policy as code, like OPA, and drift detection to catch manual changes made in the console.
Short-term containment stops the spread quickly, for example isolating hosts through EDR, disabling accounts, blocking IPs or domains and segmenting networks. Long-term containment keeps business running while preparing clean systems, such as rebuilding servers in a separate network. Responders must balance speed with evidence preservation and avoid alerting a sophisticated attacker too early if they need to understand the full scope.
11
A US customer asks your Indian SaaS company for a SOC 2 report. What is it and which type should you aim for?
SOC 2 is an attestation report by an independent auditor on a service organisation's controls against the AICPA Trust Services Criteria: security, availability, processing integrity, confidentiality and privacy. A Type I report checks control design at a point in time; a Type II checks operating effectiveness over a period, typically 6 to 12 months. Indian SaaS companies selling to US customers commonly need SOC 2 Type II.
12
Leadership wants to block all USB drives tomorrow. How would you handle this request?
I would support the goal but plan the rollout to avoid breaking business work. First, find who genuinely needs USB, such as field engineers, using endpoint logs. Then apply a device control policy through EDR or Intune that blocks mass storage by default, allows approved encrypted devices by serial number, and logs exceptions. Communicate the change, pilot it with one department, then enforce company wide.
13
What is the difference between static and dynamic malware analysis?
Static analysis examines a sample without running it: hashes, strings, imports, PE headers, YARA rule matches and disassembly. Dynamic analysis runs it in an isolated sandbox to observe processes, file changes, registry edits and network calls. Static is safe and fast but defeated by packing; dynamic shows real behaviour but malware may detect sandboxes. Analysts usually combine both in a controlled lab.
14
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.
15
Tell me about a time you made a mistake at work and how you handled it.
Situation: as a Tier 1 analyst I closed an alert as false positive without checking the user's later activity. Task: my lead found it was a real phishing compromise. Action: I owned the mistake, helped contain it, and proposed a checklist for credential alerts that includes reviewing activity after login. Result: the checklist was adopted by the shift and similar misses stopped.
16
What is single sign-on and what protocols does it use?
SSO lets a user authenticate once with an identity provider and access many applications without separate passwords. SAML 2.0 uses signed XML assertions and is common for enterprise web apps. OpenID Connect, built on OAuth 2.0, uses JSON tokens and suits modern web and mobile apps. SSO reduces password reuse and helps central control, but makes the identity provider a high-value target that needs strong MFA.
17
What is the difference between an event, an alert and an incident?
An event is any observable occurrence, like a login or a file change. An alert is an event or pattern that a tool flags as possibly malicious. An incident is a confirmed or highly likely violation of security policy that needs response, such as a compromised account. Clear definitions matter because incidents trigger escalation, legal review and regulatory reporting timelines.
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.
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
A guest Wi-Fi user can reach internal printers. What is wrong and how do you fix it?
Guest traffic is not properly isolated, likely because the guest SSID shares a VLAN with internal devices or the firewall allows inter-VLAN routing. Fix by placing guests on a separate VLAN with internet-only access, applying ACLs that deny all RFC 1918 internal ranges, and enabling client isolation on the wireless controller. Then test from a guest device and document the design.
21
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.
22
How would you verify the integrity of a downloaded installer on Windows and Linux?
Compare the file's hash with the value published by the vendor over a trusted channel, or verify its digital signature. On Windows, use PowerShell and check the Authenticode signature. On Linux, use sha256sum and gpg for signed checksum files.
Get-FileHash .\setup.exe -Algorithm SHA256
Get-AuthenticodeSignature .\setup.exe
sha256sum tool.tar.gz
gpg --verify SHA256SUMS.asc SHA256SUMS
23
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.
24
How does encryption work for data at rest in the cloud?
Most cloud storage, databases and disks encrypt data at rest by default with provider-managed keys. For more control, use customer managed keys in KMS, with key policies, rotation and logs of every use, or bring and hold your own keys for strict regulatory needs. Encryption at rest protects against physical media theft, but not against someone with valid IAM permissions, so access control remains critical.
The Digital Personal Data Protection Act 2023 governs digital personal data. Data fiduciaries need valid consent or a legitimate use, must give clear notice, protect data with reasonable safeguards, notify breaches to the Data Protection Board and affected people, and delete data when no longer needed. Data principals have rights to access, correction and erasure. Penalties go up to 250 crore rupees. The DPDP Rules 2025 phase in obligations.
26
What is certificate revocation and how is it checked?
Revocation invalidates a certificate before expiry, for example when its private key leaks. Methods are CRLs, which are signed lists of revoked serial numbers, and OCSP, where the client asks a responder about one certificate. OCSP stapling lets the server attach a fresh response to the handshake. Because revocation checking is unreliable, the industry is moving to much shorter certificate lifetimes, which reduces exposure.
27
Your servers can reach any internet destination freely. Why is this a problem and how do you introduce egress filtering?
Egress filtering controls outbound traffic, allowing only needed destinations and ports. It blocks malware call-backs, data exfiltration and servers reaching the internet directly. Many networks allow all outbound traffic because it is easier and legacy apps have undocumented dependencies. A practical approach is forcing web traffic through a proxy, blocking direct outbound from servers, and allowing exceptions only with business justification.
Map each control to the evidence an auditor will request, such as screenshots of configurations, system exports, tickets, logs and signed approvals. Keep a central evidence library organised by control ID with dates. Automate collection where possible through GRC tools that pull data from cloud, identity and ticketing systems. Sample in advance to confirm evidence covers the full audit period.
Least privilege means every user, service and application gets only the minimum access needed for its job, and only for as long as needed. It limits the damage from compromised accounts and insider mistakes. Examples are giving developers read-only production access, using separate admin accounts, and just-in-time elevation that expires after a few hours. Regular access reviews are needed because permissions tend to grow over time.
MITRE ATT&CK is a public knowledge base of adversary tactics and techniques observed in real attacks, organised in matrices for Enterprise, Mobile and ICS. Tactics are the goal, such as Persistence, and techniques are the method, such as T1053 Scheduled Task. Teams use it to map detection coverage, write threat-informed detections, plan red and purple team exercises, and describe incidents in a common language.
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.
32
How would you run a basic threat model for a new web application?
Draw a data flow diagram showing users, the web app, APIs, databases and third parties, and mark trust boundaries. Then apply STRIDE to each element: Spoofing, Tampering, Repudiation, Information disclosure, Denial of service and Elevation of privilege. For each threat, record the existing control, a risk rating and an owner. Repeat the model whenever the architecture changes, ideally during design reviews.
33
Tell me about a time you had to convince a team to follow a compliance requirement they disliked.
Situation: developers resisted mandatory code review evidence for SOC 2, seeing it as paperwork. Task: get compliance without slowing releases. Action: I explained the audit risk to customer deals and showed that branch protection rules could create evidence automatically. Result: we enabled required reviews in the repository settings, evidence became automatic and the audit passed with no finding.
34
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.
35
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.
36
How does a VPN protect traffic and what are its limits?
A VPN creates an encrypted tunnel, using IPsec, WireGuard or TLS, between a client and a network, protecting data on untrusted networks. Its limits are important: once connected, users often get broad network access, and VPN appliances are a frequent target for exploited vulnerabilities. That is why many companies move to Zero Trust Network Access, which grants per-application access after identity and device checks.
