Security Settings System Security

Caution

We recommend always using the High security setting unless you have a specific and compelling need to allow one of the insecure capabilities.

We recommend the new Maximum security setting only for those environments where the most stringent security protocols must be adhered to.

Enabling Maximum security is irreversible and has significant consequences (see “The Consequences of Enabling Maximum Security Mode” on page 54). Don’t choose this setting unless you know what you’re doing and are prepared for the consequences.

Note

All clusters in a supercluster must have the same security settings. Before attempting to join a supercluster, make sure the cluster’s security settings match those of the other members of the supercluster. You can’t change a cluster’s security settings while it’s part of a supercluster.

The following table describes the options in the Security Settings page.

Table 3-5	Fields on the Security Settings page
Field		Description
Maximum security		An extremely high security mode suitable for use where
		very strict security requirements apply.
		Once this mode is enabled, it’s no longer possible to
		reduce the security level. See caution above.
High security		Recommended setting for normal operation.
Custom security		Lets you enable one or more of the unsecured methods
		of network access listed below it.
Allow Linux console		Enables the Linux user root to log into the system using
access		SSH. This direct Linux access isn’t needed for normal
		operation, routine maintenance, or even
		troubleshooting, all of which can be done through the
		administrative GUI.
		In extreme circumstances, this option might enable
		expert Polycom Global Services personnel to more fully
		understand the state of a troubled system or correct
		problems. Enable this option only when asked to do so
		by Polycom Global Services.
