Here is a 26 Step Cyber Security Analyst Guide. This reference guide will help you be better prepared to defend against any incident your organization may have. Save this for future reference.
šµ Incident Response Process:
1. Identify the Incident - Recognize indicators of compromise (IOCs) and unusual activities.
2. Contain the incident - Isolate affected systems and limit access.
3. Eradicate the threat - Remove the root cause and affected artifacts.
4. Recover normal operations - Restore systems and validate integrity.
5. Lessons learned - Document and review the incident for future improvements.
šµ Common Attack Vectors
1. Phishing emails - Look for suspicious senders, attachments, and URLs.
2. Malware infections - Monitor for unusual behavior, system slowdowns, and network traffic.
3. Brute force attacks - Identify multiple failed login attempts.
4. Web application attacks - Watch for SQL injections, cross-site scripting (XSS), and code injections.
5. Insider threats - Monitor for unusual user activity or data exfiltration.
šµ Log Analysis
1. Review logs from various sources - Firewalls, intrusion detection systems (IDS), antivirus, and application logs.
2. Look for patterns and anomalies - Failed logins, unusual network traffic, or spikes in system resource usage.
3. Correlate events - Identify relationships between different logs to uncover the full picture.
4. Use SIEM - for efficient log aggregation and analysis.
šµ Threat Intelligence
1. Stay updated on the latest threats - Follow industry-specific sources, threat feeds, and security bulletins.
2. Understand TTPs (Tactics, Techniques, and Procedures) - used by threat actors.
3. Leverage threat intelligence platforms - for automated threat detection and prevention.
4. Share threat intelligence - with other teams and organizations for collective defense.
šµ Vulnerability Management
1. Regularly scan systems and applications for vulnerabilities - using tools like Nessus or OpenVAS.
2. Prioritize vulnerabilities - based on severity and potential impact.
3. Coordinate with system owners - for timely patching and remediation.
4. Keep an inventory of critical assets - and their associated vulnerabilities.
šµ Incident Handling Tips
1. Document all actions and findings - during incident response.
2. Communicate effectively with stakeholders - including management, IT teams, and affected users.
3. Preserve evidence for forensic analysis - if required.
4. Follow legal and regulatory requirements - for data protection and privacy.
