Learn to respond to security incidents with the command line, using journalctl for system logs, logging suspicious addresses, investigating processes, and forensic analysis. View a demo for documenting incidents.
Kali Linux offers a pre-installed toolkit for vulnerability testing, network analysis, and system hardening, enabling ethical hackers to work in isolated environments with flexible install options.
Explore linux incident response by using journalctl to view systemd logs, filter by time or service such as ssh, search for specific terms, and monitor real-time logs.
Block suspicious IP addresses with the Linux firewall (ufw) after identifying failed logins via journalctl. Enable and manage ufw rules to deny malicious IPs while keeping SSH access secure.
Investigate running processes with ps (including ps -A and ps ocs), filter with grep, monitor memory and cpu with top, and kill unwanted processes as needed.
Assess evidence after a security incident by checking file integrity of /etc/passwd and /etc/shadow, identifying recently modified files, and examining cron jobs for suspicious activity using stat and find.
Investigate incident scope with who and ps -A to spot the hacker and malware, then stop it with sudo kill -9, review changes via journalctl, and update the system.
Document and analyze Linux security incidents using terminal commands to collect logs, investigate activity, and create post-incident reports with timelines, root cause, containment, and backups.
