Unwanted network connections can be established via a poorly configured storage area network (SAN). For example, if a server with an SAN connection can be accessed from the Internet and thus compromised from the outside, the server may be used as an entrance point for attackers in order to access sensitive information stored in the SAN without authorisation. Since all security and monitoring safeguards in the IT networks of an organisation (such as firewalls or intrusion detection systems (IDS)) may be bypassed this way, the potential for damage is high.
