Service: Security Validation and Authentication Failures Per Second

Counter name: Security Validation and Authentication Failures Per Second.

Description

This counter is incremented whenever a message is rejected due to a security problem not covered by the "Security Calls Not Authorized" counter. Such problems include:

  • Client token cannot be read from the message.

  • Client token has failed authentication (for example, bad password).

  • Signature verification has failed (for example, the message has been tampered).

  • The message is a duplicate from a previous one, which can happen during a replay attack.

  • A decryption failure has occurred.

  • Some required elements (for example, missing timestamp or encrypted data block) are missing from the message.

  • Errors have occurred during TLSNEGO/SPNEGO handshake.

This counter is of performance counter type PERF_COUNTER_COUNTER, whose value is calculated using the following formula,

(N 1 - N 0 ) / ( (D 1 -D 0 ) / F)
