E-MAIL ATTACHMENT BLOCKING & VIRUS INFECTED

 E-MAIL MESSAGES

SCOPE

 

UAMS Workforce.

 

POLICY

 

E-mail viruses are becoming increasingly common.  One of the industry-wide guidelines for reducing risk of virus infection to organizational networks and workstations is to "block" high-risk attachments at the firewall level.  The block prevents virus-type attachments from becoming widely available. UAMS will utilize automatic tools to block high risk attachments within email.

 

PROCEDURE

 

1: Virus protection on the local workstations will block messages from internal users that contain viruses.

 

2: Infected messages coming to UAMS recipients from external sources or the Outlook web client will be cleaned or dropped at the email gateway.

 

3: High risk attachments (exe, bat, com, scr, vbs, pif) will be stripped from all messages both internally and externally. The user will receive the email with an “alert.txt” attached.

 

4: In the event of a major trojan or virus breakout that utilizes a particular file extension for propagation, such extension will be blocked until a patch is available to negate it
