What is the maximum number of hits you can configure within an Impersonation Protection Definition?

The maximum number of hits you can configure within an Impersonation Protection Definition is defined by the capability to recognize different indicators or patterns that trigger the protection mechanisms against impersonation attempts. Setting a limit on the number of hits ensures that the system can effectively manage and respond to potential impersonation threats while maintaining operational efficiency.

When configuring impersonation protections, defining up to six hits allows for a balance between sensitivity to potential impersonation attempts and the likelihood of false positives. Each hit represents a unique identifier or trigger that, when recognized, signals the system to take protective actions such as alerting users, quarantining messages, or blocking access.

This number is advantageous because it covers a broader range of variations in impersonation tactics while still being manageable for the email security system to analyze in real time. Configurations beyond this number could potentially lead to an overload of alerts or responses that may hinder system performance or lead to user frustration.

Thus, the option of six hits stands as the optimal choice for configuring impersonation protections within Mimecast’s framework, making it the correct answer.
