  • FTP Logon Restrictions in IIS 8

    One of the biggest asks from our customers over the years was to provide a way to prevent brute-force password attacks on the FTP service. On several of the FTP sites that I host, I used to see a large number of fraudulent logon requests from hackers that were trying to guess a username/password combination. My first step in trying to prevent these kinds of attacks, like most good administrators, was to implement strong password requirements and password lockout policies. This was a good first step, but there is an unfortunate downside to password lockout policies - once a hacker locks out a user account, that means that a valid user is locked out of their account. What's more, a hacker can continue your server.
