SUMMARY: The DoD site license for IBMAV has been extended through 30 September 1995 by Defense Information System Agency contract DCA100-95-M-0649. BACKGROUND: IBMAV is available from the ASSIST BBS aand FTP servers (see ASSIST Information Resources paragraph below for connection information). The IBMAV software and documentation is located in the IBMAV File Area on the BBS, which is restricted to access by DoD personnel only. In order to verify a user as being a member of the DoD community, ASSIST must perform a call back to a DSN phone number provided by the individual requesting access to the IBMAV file area, or receive the access request in an e-mail message from a MILNET address. If neither of these options are available, other arrangements will be made. On the ASSIST FTP server, the IBMAV software and documentation files are available in the /pub/IBMAV directory. IBM provides monthly virus signature updates for IBMAV which are available on the ASSIST BBS and FTP systems. The updates are normally issued on or about the 20th of each month and consist of single self extracting zip that includes directions for installing the update. IMPACT: Failure to maintain and use an up to date AV tool places systems at risk of malicious code infection. RECOMMENDED SOLUTIONS: Obtain, install, and maintain an AV tool on all PC systems. Ensure the AV tool is kept up to date by obtaining and installing the most current version of the software upgrades as soon as they are available. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> ASSIST is an element of the Defense Information Systems Agency (DISA), Center for Information Systems Security (CISS), that provides service to the entire DoD community.
