Description
Analogue ISDN Line Security Policy
The Analogue ISDN Line Security Policy helps organisations manage legacy communication systems while maintaining high standards of security. Although modern networks rely on digital protocols, many businesses still use analogue or ISDN lines for backup, faxing, or specific operational needs. These lines can introduce vulnerabilities if left unsecured.
This policy offers clear and practical guidance to secure analogue and ISDN line connections, particularly where they interface with critical IT systems. It ensures unauthorised access, data interception, or system breaches are prevented through a structured and compliant approach.
Why Your Organisation Needs This Policy
Even legacy systems can expose your business to threats. Attackers often target overlooked areas of infrastructure, such as fax lines or unsecured PBX systems. The Analogue ISDN Line Security Policy ensures that these systems are monitored, access is controlled, and the risk of exploitation is significantly reduced.
It outlines key measures such as regular line audits, access restrictions, port blocking, encryption use (where applicable), and system logging. By integrating these measures, your business meets industry security standards while continuing to operate essential services.
