Exam N10-009 Topic 4 Question 317 Discussion

The CIA triad (Confidentiality, Integrity, Availability) is a foundational security model used in Network+ (N10-009) to evaluate risk and guide prioritization of mitigations. By categorizing assets and threats based on how they could impact confidentiality (data exposure), integrity (unauthorized alteration), or availability (service disruption), administrators can better understand which attacks from external actors matter most to the business and which controls to apply first. For example, a public-facing portal might prioritize availability protections (DDoS mitigation, redundancy), while sensitive customer records demand strong confidentiality controls (encryption, access control), and financial systems require integrity controls (logging, validation, change control). This model helps translate "threats" into business impact, which is central to deciding what to mitigate.
Compliance benchmarks support meeting regulatory/industry requirements, but they don't inherently provide a conceptual lens for analyzing external attacker impact across all systems. SAML is a federation
/authentication standard, not a risk model. A honeypot can provide insight into attacker behavior, but it doesn' t broadly structure risk prioritization the way CIA does. Therefore, CIA triad is the best answer.
