Endpoint hardening is a supplementary step that can provide greater protection from various forms of attacks. It may also make it difficult for users to gain information about the system by preventing the phone from relaying certain information.
Determine from business requirements the fields and options required, and those that will not be required. Those that are not required can be disabled as part of endpoint hardening.
To harden an endpoint from various forms of attacks and vulnerabilities, perform the following:
Navigate to the endpoint to be hardened (Device | Phone).
Under the Product Specific Configuration Layout section, enable or disable the following fields as required:
PC Port
Settings Access
Gratuitous ARP
PC Voice VLAN Access
Web Access
Click on Save.
Click on Reset.
Repeat these steps for each endpoint that requires hardening.
