Study Notes

Fundamental Security Concepts

Information security principles form the foundation for advanced topics.
Core concepts include Confidentiality, Integrity, and Availability (CIA).
CIA triad is the building block of information security.

CIA Triad

Confidentiality: Ensures only authorized users access data or resources.
- Examples include password-protected files, encryption, and secure channels.
Integrity: Maintains data accuracy and trustworthiness.
- Measures like checksums, digital signatures, and hashing algorithms.
Availability: Ensures resources are accessible to authorized users when needed.
- Includes backup systems, fault tolerance, and high availability configurations.
- "Keeping Secrets (Confidentiality), Keeping it Real (Integrity), and Keeping it Accessible (Availability)".

Non-repudiation

Provides assurance that an operation or transaction occurred and was initiated by a specific entity.
Digital signatures and stringent authentication methods establish non-repudiation.

Authentication, Authorization, and Accounting (AAA)

Authentication: Proves user identity.
Authorization: Determines user permissions and actions.
Accounting: Tracks user activity.
- Analogy: Showing ID (authentication), boarding pass limits (authorization), and travel records (accounting).

Physical Security

Measures to secure physical assets and infrastructure.
- Bollards, access control vestibules, fencing, video surveillance, security guards, access badges.

Deception and Disruption Technology

Technologies (honeypots, honeynets, etc.) mislead attackers.
Collects information about attacker methods.

Zero Trust

Assumes no trust by default, even for internal systems.
Focuses on limiting access.
Core principle: "Never Trust, Always Verify".

Data Plane, Implicit Trust Zones, Subject/System, Policy Enforcement Point

Data plane controls data flow within the network.
Implicit Trust Zones allow data free flow within network segments.
Policy Enforcement Points apply Zero Trust policies.

Gap Analysis

Identifies the difference between current and desired security posture.
Essential for assessing existing security controls and determining needs for improvements.

Adaptive Identity

Permissions and access may adjust based on actions, devices, and contexts.
