Who is Vulnerable?
Vulnerability Description	Brute Force Attacks are a significant threat on users privacy. Using Brute Force, remote attackers attempt to gain access to unauthorized areas of a target system, such as FTP accounts, e-mail accounts and databases. By trying to repeatedly log in to an SSH server using different passwords, it is possible to crack a user account on the remote target and compromise it. There are cases in which certain traffic, although not intended for malicious use, is very unsafe, since it may transfer shellcode which is undetectable by IPS.
