The lack of a proper audit trail after a security incident can hamper forensic efforts.
Windows Communication Foundation (WCF) offers the ability to log successful and/or failed authentication attempts. Logging failed authentication attempts can warn administrators of potential brute force attacks. Similarly, logging successful authentication events can provide a useful audit trail when a legitimate account is compromised.
