Study Notes
Cybersecurity Incident Response
- The team conducts an attack simulation exercise (TTX) to assess their response
- The team removes the threat from the system, reviews affected and unaffected systems
- The team assigns an Incident Manager (IM) to lead the response, manage communications and delegate tasks
- The Incident Manager does not perform any technical duties
- The team assigns a Tech Manager (TM) to serve as a subject matter expert, bringing in technical experts
- The team assigns a Communications Manager (CM) who interacts with external stakeholders
- The team holds a formal retrospective meeting to gather lessons learned
- The team reviews the incident to identify the root cause, how it breached the network, and vulnerabilities
Cybersecurity Incident Response Technologies
- Attack Surface Management (ASM) is the process of identifying, monitoring and reducing potential attack surfaces across the digital environment
- ASM solutions automate the discovery, analysis, remediation and monitoring of vulnerabilities
- Endpoint Detection and Response (EDR) provides endpoint protection against malicious activities
- EDR software automatically protects users, endpoint devices and IT assets against cyberthreats
- EDR collects data from all endpoints on the network and analyzes it in real-time
- Security Information and Event Management (SIEM) aggregates and correlates security event data from disparate internal security tools and devices
- SIEM uses a process of risk analysis, detection, investigation, containment and vulnerability scans
- Extended Detection and Response (XDR) unifies security tools, control points, data and telemetry sources, and analytics across the IT environment
AI and Incident Response
- AI quickly detects and controls incidents before escalation
- AI uncovers previously unmonitored network assets and maps relationships between assets
- AI analyzes network traffic, logs, and other data sources in real time to identify anomalies and patterns
- AI analyzes user behaviour and system interactions to identify deviations
- AI processes large amounts of unstructured from multiple sources
- AI automatically analyzes suspicious files or URLs to determine if they are malicious
Zero Trust Framework
- The Zero Trust framework assumes that threats could be both inside and outside the network
- Every access request must be verified
- Key principles include never trust, always verify and least privilege access
- Micro-segmentation involves dividing the network into smaller segments that have their own access controls
Psychology of Social Engineering
- Social engineering involves manipulating human behaviours, emotions and cognitive biases to deceive individuals
- Exploits human nature rather than technical vulnerabilities
- Authority plays a huge role in social engineering
- People tend to comply with requests from authority figures
- Urgency and Scarcity increases the risk of uninformed decisions
Mitigation Strategies and Best Practices
- Implement strong password policies and multi-factor authentication
- Utilize least privilege access
- Adopt micro-segmentation
- Conduct security assessments and penetration testing
- Educate and train users on security best practices
- Implement data encryption
- Integrate threat intelligence
