Security protocol at BAS prohibits compressed files from entering the network. A compressed file (such as one ending with .zip, .exe or .qt) may contain an undetectable virus or may cause malicious software to download onto the computer of the recipient who opens the file. BAS security can detect a compressed file even if the sender removes the extension name.
If someone tries to send a message containing a compressed file to a BAS employee, the sender will receive a bounce-back message indicating that the message did not reach the intended recipient. The individual should re-send the message without the compressed attachment.
