Why do I need PitBull if I use PKI or SSL?
Session encryption and communication security like SSL and PKI can protect privacy while information is in transit, but they cannot protect data residing on the servers themselves. Once the information has been transmitted and decrypted, the same information that was protected en route is now made vulnerable to attack while stored on the server. In the case of hard drive or full media encryption, the same problem exists with the encryption keys themselves. Consider a system in which encryption keys are machine generated 64-character strings. Cracking such encryption may seem a daunting task, but if a user can gain access to the file on the system where the strings (or the encryption algorithm) reside, the encryption scheme fails entirely.
