1.2 - Understand and apply security concepts
Five Pillars of Information Security
The cornerstone of information security, these principles must be maintained throughout all security activities:
-
Confidentiality
- Definition: Preventing unauthorized disclosure of information
- Controls: Encryption, access controls, data classification, steganography
- Violations: Human error, admin mistakes, policy oversights, misconfiguration
- Concepts: Sensitivity, discretion, criticality, concealment, secrecy, privacy, seclusion, isolation
- Key Point: Use network traffic padding to prevent traffic analysis attacks
-
Integrity
- Definition: Preventing unauthorized modification and maintaining data accuracy
- Controls: Hash verification, digital signatures, input validation, change management, interface restrictions
- Threats: Unauthorized changes, mistakes by authorized users, malicious modifications
- Conditions: Accuracy, truthfulness, validity, accountability, responsibility, completeness, comprehensiveness
- Key Point: Integrity includes maintaining internal consistency of data objects
-
Availability
- Definition: Ensuring authorized access to resources when needed
- Controls: Redundancy, backups, fault tolerance, DoS prevention, monitoring
- Threats: System failures, attacks, natural disasters, human error
- Conditions: Usability, accessibility, timeliness
- Metrics: Uptime percentages (99.9%, 99.99%, 99.999%)
-
Authenticity
- Definition: Data is genuine and originates from its claimed source
- Implementation: Digital certificates, cryptographic signatures, chain of custody
- Relationship: Closely tied to integrity and non-repudiation
- Verification: Strong confidence in data source and unchanged state
-
Non-repudiation
- Definition: Ensures subjects cannot deny their actions or involvement
- Requirements: Strong identification, authentication, authorization, auditing, accounting
- Technical Controls: Digital signatures, timestamps, cryptographic proofs
- Legal Aspect: Provides evidence for legal proceedings
Memory Aid: Confidentiality Integrity Availability = CIA, plus Authenticity and Non-repudiation
AAA Services (Foundation of Access Control)
- Identification: Subject claims an identity (username, account number)
- Authentication: Proving the claimed identity (password, biometric, certificate)
- Authorization: Determining what the authenticated subject may access
- Auditing: Recording activities and events for later review and accountability
- Accounting: Reviewing audit logs to ensure compliance and investigate violations
Extended Model: Some frameworks include Identification as a separate first step (I-AAA)
- Accounting: Reviewing logs to hold users accountable
Protection Mechanisms
- Defense in Depth: Multiple layered controls
- Abstraction: Grouping similar elements for collective security controls
- Data Hiding: Logical compartmentalization to prevent access
- Encryption: Hiding meaning of communications
