Definition: Persistent connections relate to an “always on” condition with the Internet, network or another computer. Employees walking away from an Internet connection without closing it down or for that matter an “always-on” connection to a supplier could pose security challenges. Such a condition means that an avenue for a threat to follow or pathway for a vulnerability to be exploited by an malicious user is always open. An extended exposure to the Internet or a third party over which little control can be exercised has the potential of being a significant vulnerability.
Its Relevance: An organization must address the security issues related to constant online connections and how relatively permanent connections should be implemented. The policies should be formal and part of the business’ security policies. Users who fail to terminate an on-line connection are actually maintaining a system vulnerability. Maintaining such connections "leave the front door" to an information system open.
