The SEC_PROTOCOL_ERROR_TRACE_ACTION setting determines the Oracle's server's logging response level to bad/malformed packets received from the client by generating ALERT, LOG, or TRACE levels of detail in the log files. This setting should have a value of LOG unless the organization has a compelling reason to use a different value because LOG should cause the necessary information to be logged. Setting the value as TRACE can generate an enormous amount of log output and should be reserved for debugging only. Rationale: Bad packets received from the client can potentially indicate packet-based attacks on the system, which could result in a denial-of-service condition.
Solution
To remediate this setting, execute the following SQL statement. ALTER SYSTEM SET SEC_PROTOCOL_ERROR_TRACE_ACTION=LOG SCOPE = SPFILE;
