Due to increase risk of virus attacks and vulnerabilities to NJVC’s network, NJVC LLC has prohibited the use of the following programs:
Ø AOL Instant Messenger
Ø Yahoo Messenger
Ø MSN Messenger
Ø Outside email sources (i.e. Hotmail, Yahoo Mail, AOL Mail, etc.)
We need your support to help protect our network and our companies’ information. An IT team member will be coming around to remove any related software from your computer in the near future.
When accessing web-based external email servers there's an increased risk of infection. A web browser, such as Netscape or Internet Explorer (or Outlook Express which uses Internet Explorer) can be used to directly access an external mail server. This allows a user to access email from that external server-email that bypasses the appliance and NJVC Exchange server anti-virus and content scans. Email attachments that are infected or that have prohibited extensions are not stripped as they would be if they were sent to an NJVC-LLC mail address.
Programs such as AOL Instant Messenger (AIM) allow remote individuals to execute commands on, and gain full remote control of, any Windows machine with AIM installed. While Yahoo Messenger allows a remote user may be able to cause arbitrary code to be executed on the target user's system when the target user attempts to download a file.
NJVC IT/IS department rely on our firewall to protect our network but the best protection solution for NJVC is to discontinue use of such mail programs and disable any instant Messenger service on all NJVC desktops and at NJVC’s firewall.
You cannot receive and process on your NJVC workstation email received directly from an external email server via a browser. All email from sources external to NJVC must come through NJVC ‘s Exchange server. (This is done by having the sender address the email to your NJVC-LLC address)
Thank you for your cooperation
