Study Notes
- CIA stands for Confidentiality, Integrity, and Availability.
- Non-repudiation is a key security principle.
- AAA stands for Authentication, Authorization, and Accounting.
Authenticating Systems and People
- Authentication involves verifying the identity of users and systems.
- Authorization models define what authenticated users or systems can access and do.
- Gap analysis identifies the differences between desired and actual security measures.
Zero Trust
- Zero Trust is a security framework based on the principle of "never trust, always verify."
Control Plane
- Adaptive identity ensures identities are continuously validated based on context and behavior.
- Threat scope reduction minimizes the impact of potential breaches.
- Policy-driven access control enforces granular access permissions based on predefined policies.
- The Policy Administrator is responsible for managing and defining security policies.
- The Policy Engine evaluates access requests against defined policies.
Data Plane
- Implicit trust zones are eliminated in a Zero Trust architecture.
- Subjects/Systems are entities requesting access to resources.
- The Policy Enforcement Point enforces access control policies for resource access.
Physical security
- Physical security involves measures to protect physical assets and facilities.
- Bollards are used to prevent vehicle-based attacks.
- Access control vestibules control entry and exit points.
- Fencing establishes a physical perimeter.
- Video surveillance monitors and records activities.
- Security guards provide on-site security presence.
- Access badges control entry to restricted areas.
- Lighting enhances visibility and deters intruders.
Sensors
- Infrared sensors detect heat signatures.
- Pressure sensors respond to physical force.
- Microwave sensors detect movement.
- Ultrasonic sensors use sound waves to detect objects.
Deception and disruption technology
- Deception technology aims to mislead and disrupt attackers.
- A honeypot is a decoy system designed to attract and trap attackers.
- A honeynet is a network of honeypots.
- A honeyfile is a fake file designed to lure attackers.
- A honeytoken is a decoy token or credential used to detect unauthorized access.
