Question 1030
An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft. Before changing security policy, what evidence should the engineer examine FIRST?
Explanation
Correct Answer
Inspect Duo authentication events, factor methods, trusted device enrollment, health signals, and application access policies. This checks the relevant condition before an engineer modifies production access or detection behavior. Multifactor authentication strengthens login assurance, while device trust and adaptive controls independently evaluate session risk. The controlled response would be: Enforce appropriate Cisco Duo MFA and device trust checks for protected applications, considering user role and device security status. Situation: An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft.
Incorrect Answers
Inspect detection search logic, sourcetype fields, incident assignment, playbook permissions, and result audit trail. This evidence addresses Splunk event orchestration and response workflows; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect Duo authentication events, factor methods, trusted device enrollment, health signals, and application access policies. Situation: An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft.
Inspect SSO federation setup, conditional access rules, authenticator strength, location signals, and Duo activity logs. This evidence addresses Duo Adaptive Access and SSO context; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect Duo authentication events, factor methods, trusted device enrollment, health signals, and application access policies. Situation: An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft.
Inspect queried subdomain patterns, TXT requests, query response rates, domain age, and originating host process. This evidence addresses DNS tunneling exfiltration detection; it would not establish the primary issue here. The diagnostic evidence needed for this scenario is: Inspect Duo authentication events, factor methods, trusted device enrollment, health signals, and application access policies. Situation: An account has repeated denied Duo prompts from an unfamiliar location before a user reports attempted password theft.
