In log filtering, what indicates a 'suspicious' sign-in according to the criteria provided?

• A. High severity warnings
• B. Any user access attempt
• C. Log entries with successful auth statuses
• D. Access denied logs only

Answer: (A)

High severity warnings are indicative of a 'suspicious' sign-in because they represent a significant risk that may require further investigation. These warnings often point to anomalous behaviors, such as logins occurring from unusual geographic locations, multiple failed login attempts preceding a successful sign-in, or logins at atypical times. By focusing on high severity alerts, administrators can prioritize their responses to potential threats and concentrate their resources on the most concerning incidents. This practice helps in identifying potential security breaches or unauthorized access attempts more effectively than simply monitoring all user access attempts or logs marked as successful authentication statuses, which do not inherently indicate a security issue. Additionally, access denied logs mainly indicate failed attempts and may not provide a comprehensive view of potentially malicious activity, especially if they are not accompanied by other signs of unusual behavior. Hence, focusing on warnings that have been classified as 'high severity' equips administrators with the most relevant context to make informed decisions about security incidents.
