Study Notes
Incident Response Activities
- Analysis identifies the source of an incident by collecting evidence, determining root causes, assessing scope and impact, and understanding attacker motives.
- Following detection, analysis precedes containment, eradication, recovery, and lessons learned.
Vulnerability Management
- After a vulnerability assessment, rescanning the network is crucial to confirm that identified vulnerabilities have been remediated.
Insider Threats
- Activities such as unauthorized after-hours remote logins and transferring data to personal devices indicate an insider threat, originating from authorized personnel within the organization.
Brute Force Attacks
- Multiple failed login attempts in a short period suggest a brute force attack, characterized by attempts to guess a user's credentials using various combinations.
Data Protection Methods
- Masking is preferred for displaying only the last four digits of credit card numbers, preventing unauthorized access while allowing partial visibility.
- Ransomware, identifiable by file extensions like .ryk, encrypts files and demands ransom for decryption, affecting entire systems.
Application Availability
- In developing web applications for health emergencies, availability is paramount to ensure users can access services when needed.
Incident Response Exercises
- Tabletop exercises simulate incident response procedures, helping organizations identify weaknesses and improve communication and coordination.
Certificate Validation
- OCSP (Online Certificate Status Protocol) allows real-time validation of certificates' revocation status, offering a faster alternative to Certificate Revocation Lists (CRLs).
Safety Controls
- Safety controls, such as fire alarms and emergency exits, should fail open to protect human life during emergencies, allowing continued operation or access in case of failure.
- Other security controls, like remote access points and logical controls, should fail closed to prevent unauthorized access during errors.
