Episode 107 — Spotlight: Security Categorization (RA-2)

Framework: NIST 800-53 Audio Course ·

2025/10/20

Security Categorization (RA-2) anchors the entire control selection process by determining the potential impact of a loss of confidentiality, integrity, or availability for each system. For exam readiness, recognize that RA-2 is not a clerical step; it ties mission objectives, data sensitivity, and operational dependencies to an impact level that drives baselines, overlays, and parameter choices. Effective categorization considers data types processed or stored, critical business functions

Framework: NIST 800-53 Audio Course ·

2025/10/20

Vulnerability Monitoring and Scanning (RA-5) ensures organizations continuously identify weaknesses in systems, applications, and configurations before adversaries do. For exam purposes, understand that RA-5 is broader than scheduled scans; it encompasses a full lifecycle that ingests threat intelligence, evaluates exposure across on-premises and cloud assets, and tunes discovery methods to evolving technology stacks. A credible RA-5 implementation maintains current asset inventories,

Episode 102 — Spotlight: Incident Reporting (IR-6)

Framework: NIST 800-53 Audio Course ·

2025/10/20

Incident Reporting (IR-6) ensures that detected security incidents are promptly communicated to appropriate parties so that response and oversight occur without delay. For the exam, candidates must understand that this control establishes reporting thresholds, timelines, and communication paths based on incident type and severity. Reports typically include event details, affected systems, scope, initial impact assessment, and corrective actions taken. IR-6 supports both internal

Episode 101 — Spotlight: Incident Handling (IR-4)

Framework: NIST 800-53 Audio Course ·

2025/10/20

Incident Handling (IR-4) defines how organizations detect, analyze, contain, eradicate, and recover from security incidents in a structured and repeatable manner. For exam purposes, understand that this control operationalizes the entire incident response process by prescribing standard procedures, communication paths, and decision-making authorities. IR-4 ensures incidents are managed consistently across systems, regardless of origin or severity. The control emphasizes preparedness,

Episode 100 — Spotlight: Least Functionality (CM-7)

Framework: NIST 800-53 Audio Course ·

2025/10/20

Least Functionality (CM-7) requires systems to provide only the capabilities essential to mission needs, removing or disabling unnecessary services, features, roles, and ports. For exam purposes, understand that reducing functionality directly reduces attack surface and operational complexity, improving both security and reliability. CM-7 builds on CM-2 and CM-6 by ensuring that what is not in the baseline stays out of production and that permitted functions are explicitly justified. The

Framework: NIST 800-53 Audio Course ·

2025/10/20

Configuration Change Control (CM-3) governs how proposed modifications to systems and baselines are evaluated, approved, implemented, and recorded. For exam readiness, understand that CM-3 is the gatekeeper preventing unvetted changes from introducing vulnerabilities or breaking compliance. The control requires a documented process that captures the change description, risk and impact assessment, security review, testing evidence, approval authority, and rollback plan. CM-3 applies to code

Episode 90 — Spotlight: Authenticator Management (IA-5)

Framework: NIST 800-53 Audio Course ·

2025/10/20

Authenticator Management (IA-5) ensures that credentials—passwords, tokens, keys, or certificates—are created, stored, distributed, and revoked securely. For the exam, candidates should understand that IA-5 defines the lifecycle of authenticators, addressing generation strength, protection during storage and transmission, and prompt revocation when compromised or no longer needed. This control prevents reuse, sharing, or weak credential creation that could undermine authentication
