The expo­sure of Anony­mous FTP

FTP is often con­fig­ured to allow anony­mous access. Some vari­ants even default to allow­ing it. Anony­mous access enables users (and hack­ers) to access the server via FTP with­out pro­vid­ing proper logon credentials.

Servers allow­ing Anony­mous FTP are tar­gets for hack­ers dis­trib­ut­ing pirated video and music. FTP attacks almost always include an attempt to log on anonymously.

FTP/Sentry’s user ID view pro­vides quick access to the answer whether and how much anony­mous FTP access actu­ally is happening.
