Zenitel, a supplier of intelligent and interoperable communication solutions, announced the release of its Cybersecurity Hardening Guide. The Zenitel Cybersecurity Hardening Guide follows controls outlined by the Center for Internet Security (CIS) SecureSuite, of which Zenitel has been a member for many years. CIS harnesses the power of the global IT community to safeguard private and public organizations against cyber threats. The Zenitel Cybersecurity Hardening Guide begins with information about the CIS controls, and then follows with steps that a company should take, including assessing risk and security levels, managing credentials and passwords and more. A cybersecurity checklist outlines specific tasks and expectations linked to relevant CIS controls that a company should follow and implement to ensure its networked IP intercom devices are cybersecure.
