CompTIA CAS-005 Exam Dumps - Actual Questions Answers

Comprehensive and Detailed Explanation:

Understanding the Security Event:

Administrator accounts are highly privilegedand require strict monitoring.

Server 4 shows failed login attempts for the administrator account.This could indicate abrute-force attack or unauthorized access attempt.

The fact thatnone of the admin login attempts were successfulsuggestssomeone was trying to guess the credentials.

Why Option D is Correct:

Failed logins for administrator accounts are a critical security concern.

If an attacker gains access, they couldescalate privileges and compromise the network.

Investigatingunauthorized admin login attemptsshould be thetop priorityin a log audit.

Why Other Options Are Incorrect:

A (Endpoint not submitting logs):While this is concerning, it does not indicate anactive attack.

B (Lateral movement):There's no evidence of a compromised account moving between servers yet.

C (Misconfigured syslog server):False negatives are a possibility, but thefailed admin loginsare real.

Understanding Business Impact Analysis (BIA):

ABIA assesses the effects of disruptionsto an organization's operations.

It helpsprioritize resourcesbased on the potential impact ofdowntime, compliance issues, and critical processes.

Why Options B, C, and F are Correct:

B (Applicable contract obligations)→ Many companies havelegal and compliance obligationsregarding downtime, availability, and SLAs. This information helps determine whatrisk levelsare acceptable.

C (Costs associated with downtime)→ BIA quantifies the financial impact of system failures. Knowinglost revenue, regulatory fines, and recovery costshelps in planning.

F (Critical processes)→ Identifyingcore business processesallows an organization toprioritize recovery effortsandmaintain operational continuity.

Why Other Options Are Incorrect:

A (Inventory details)→ While useful for asset management, it doesnot directly impact business continuity planning.

D (Network diagrams)→ These help in security architecture but arenot directly related to the financial/business impact analysis.

E (Contingency plans)→ BIA isperformed before contingency planningto identifywhat needs protection.

User behavior analytics (UBA)detectsanomalous activityby analyzing historical patterns and comparing them to recent behavior. The time shift in account activity suggestspotential compromise or misuse.

TTP-based inquiries (A)focus on known attack tactics, techniques, and procedures but do not involve behavior tracking.

Adversary emulation (C)simulates attacks but does not analyze real data trends.

OSINT analysis (D)gathers intelligence from public sources, which is unrelated to internal account behavior analysis.
