Study Notes

Threat Categorization

Known Threats: Recognizable malware or attacker infrastructure linked to malicious activity.
Unknown Threats: Unidentified threats, often evolving; target vulnerable assets, weak credentials, or specific industries.

User and Attacker Behavior Analytics

User Behavior Analytics (UBA): Identifies anomalous behaviors, indicating possible unknown threats, by establishing a baseline of normal activity and using analytics or machine learning for detection.
Attacker Behavior Analytics (ABA): Exposes attack tactics, techniques, and procedures (TTPs) like malware, cryptojacking, and data exfiltration, allowing better understanding of attacker methods.

Importance of Early Detection

Breach Timing: Undetected attacks allow further infiltration; early alerts through UBA and ABA are critical for security operations centers (SOCs) to respond effectively.

Incident Response Framework

Stakeholder Involvement: Critical for successful incident response; ensures clarity on responsibilities and communication channels.
Incident Response Essentials:
- Clarity on responsibility at each phase.
- Well-understood communication chain.
- Awareness of escalation processes.

Security Traps

Intruder Traps: Includes honeypots or honey credentials that appear valuable to attackers, triggering alerts for security teams when accessed.

Threat Hunting

Proactive Defense Technique: Security analysts actively seek out potential threats in the organization’s network and endpoints, rather than waiting for alerts; requires experienced personnel.

Security Solutions

SIEM (Security Information and Event Management): Collects enterprise security data; used to detect vulnerabilities but lacks depth in event analysis and response capabilities.
NTA (Network Traffic Analysis):
- Monitors network activity and availability.
- Detects anomalies, malware, and viruses within the specific network silo.
- Limited in detecting cross-silo threats.
EDR (Endpoint Detection and Response):
- Real-time monitoring of all connected endpoints.
- Initiates automated response mechanisms upon detecting suspicious activity, escalating alerts for further investigation.
XDR (Extended Detection and Response):
- Integrates various traditional security features from NTA and SIEM.
- Collects data across multiple sources: network, cloud, systems, and endpoints.
- Utilizes artificial intelligence and threat intelligence for comprehensive threat detection and narrative building.
