CompTIA Security+ SY0-701 Practice Question
During a routine security check, a security specialist notices an alert indicating repeated authentication failures followed by a system access event. When examining the system's security logs to assess the situation, which pattern would most likely suggest a compromise?
Continuous internal traffic to the network gateway as part of normal activity monitoring
Routine sign-ins at regular intervals from known network addresses associated with automated maintenance tasks
Repeated credential validation errors immediately followed by an entry clearance recorded from a single identifier
Regular status updates confirming that the security mechanisms are fully operational
