InformationAn MOTD banner is displayed when a terminal connects, before a login occurs. This banner is useful for sending messages that affect all users (such as impending system shutdowns). This banner can also be used to notify unauthorized users of any penalties to accessing the device, or any logging that may be configured
Network banners are electronic messages that provide notice of legal rights to users of computer networks. From a legal standpoint, banners have four primary functions.
Banners may be used to generate consent to real-time monitoring under Title III
Banners may be used to generate consent to the retrieval of stored files and records pursuant to ECPA.
in the case of government networks, banners may eliminate any Fourth Amendment 'reasonable expectation of privacy' that government employees or other users might otherwise retain in their use of the government's network under O'Connor v. Ortega, 480 U.S. 709 (1987).
In the case of a non-government network, banners may establish a system administrator's 'common authority' to consent to a law enforcement search pursuant to United States v. Matlock, 415 U.S. 164 (1974).' (US Department of Justice APPENDIX A: Sample Network Banner Language)
