Go through each question and its explanation. Use this set as a focused practice pack for Incident Response.
Reviewing real cases helps analysts understand attacker behavior and common failure points. Simulating these scenarios through tabletop exercises ensures quicker recognition and better coordination during future incidents. It transforms experience into proactive defense capability.
For complete preparation, combine this set with full subject-wise practice for Incident Response. You can also explore other subjects and sets from the links below.
Use secure internal channels only, maintain a single source of truth, and limit updates to verified facts. Avoid speculation and ensure communication between technical teams, management, and legal representatives remains coordinated. Timely, accurate updates prevent misinformation and panic.
Immediate containment prevents the malware from spreading laterally. Once isolated, forensic teams can analyze the encryption type and restore data from clean backups.
Incident handling must follow a structured order: contain first, analyze second, communicate transparently, and finally apply remediation and preventive controls.
Evidence must be preserved before any confrontation. Collect workstation logs, emails, and external device records to build a timeline and confirm data transfer activity.
SIEM correlation rules connect multiple low-level alerts into a single incident narrative. For example, repeated failed logins followed by privilege escalation and outbound traffic can be correlated into one attack chain, reducing alert fatigue and highlighting true threats.
A timeline helps analysts reconstruct attacker activity step-by-step — from initial compromise to exfiltration. It reveals dwell time, lateral movements, and the effectiveness of detection controls. Accurate timestamps also support legal evidence presentation and RCA documentation.
Short-term containment isolates affected systems quickly — disconnecting hosts or disabling accounts — to stop attack spread. Long-term containment focuses on building stable configurations such as patching vulnerabilities, hardening access controls, and monitoring recovery systems before returning them to production.
Confirm systems are clean through re-imaging or malware scanning, validate integrity using hashes, and test backups in an isolated environment. Reconnecting too soon can reintroduce the threat, so coordinate restoration with containment verification and updated monitoring rules.
Notifications should follow regulatory timelines like GDPR’s 72-hour rule. Reports must include nature of breach, affected data types, and mitigation steps. Coordination with legal and PR teams ensures accurate, compliant, and reputation-safe disclosure.
Dynamic sandboxing reveals how the executable behaves — network calls, file drops, or registry edits — helping confirm whether it is malicious before mass remediation.
The first step is analysis — not deletion. Security teams must examine headers, links, and attachments to extract indicators such as malicious domains or IPs before containment or reporting actions.
CDN and WAF providers filter malicious requests and absorb excess traffic. Rate-limiting and geo-blocking further help to control attack impact without service downtime.
