Domain 1: Security and Risk Management

Weight: 16% of exam

This domain encompasses the fundamental security concepts, governance principles, risk management practices, and legal/regulatory frameworks that form the foundation of information security management. As the highest-weighted domain, it requires deep understanding of security principles and their practical application in organizational contexts.

1.1 - Understand, adhere to, and promote professional ethics

ISC2 Code of Professional Ethics

The foundation of the CISSP profession, these four canons guide all professional activities:

  1. Protect society, the common good, necessary public trust and confidence, and the infrastructure

    • Highest priority - society comes before employer or self
    • Maintaining public trust in information systems
    • Protecting critical infrastructure
  2. Act honorably, honestly, justly, responsibly, and legally

    • Personal integrity in all professional activities
    • Compliance with applicable laws and regulations
    • Ethical decision-making processes
  3. Provide diligent and competent service to principals

    • Maintaining professional competence through education
    • Providing accurate and honest advice
    • Avoiding conflicts of interest
  4. Advance and protect the profession

    • Mentoring others in the profession
    • Contributing to the body of knowledge
    • Maintaining professional standards

Memory Aid: Society, Honor, Diligence, Advance the profession

Organizational Code of Ethics

  • Organizational-specific guidelines: Tailored to company culture and industry
  • Professional conduct standards: Expected behaviors and accountability measures
  • Conflict of interest policies: Guidelines for identifying and managing conflicts
  • Whistleblower protections: Safe reporting mechanisms for ethical violations

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:

  1. 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
  2. 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
  3. 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%)
  4. 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
  5. 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
