incident-response

A cybersecurity incident response framework involves six essential phases: Preparation, Identification, Containment, Eradication, Recovery, and Lessons Learned. This methodology ensures structured mitigation, threat removal, and system restoration while preserving evidence for post-incident analysis.

To handle a suspected data breach, you must follow structured incident response steps: contain the breach to prevent further loss, analyze logs and network traffic to identify the source, eradicate the threat, and recover affected systems while preserving digital evidence for forensics.

Yes, you can use Splunk and ELK for security log analysis during an incident. These tools are integrated into the incident response workflow to help identify anomalies, track malicious activity, and support network traffic inspection and digital forensics.

Memory forensics for a malware outbreak is performed using tools like Volatility. During the identification and analysis phases, you capture and inspect memory dumps to detect malicious processes, uncover rootkits, and gather evidence of unauthorized access or malware behavior.

The best way to contain a malware infection is to isolate affected systems from the network immediately during the containment phase. This prevents lateral movement while you perform network traffic inspection with tools like Wireshark and tcpdump to trace the infection vector.

Yes, you need to preserve network traffic logs for unauthorized access investigations. Capturing traffic with tools like Wireshark and tcpdump provides critical forensic evidence to identify the intrusion vector, support eradication, and guide the recovery and post-incident analysis phases.
