Description
Many instant messaging systems have known vulnerabilities, some of which allow an adversary to install malware on the device. This malware can then be used to obtain sensitive information or further compromise DoD information systems. Restricting IM traffic to DoD-authorized IM systems mitigates the risk of using IM technology.
