Introduction
As networks become more complex, the requirements for data security become more
important. It is no longer feasible to consider that the DNCS exists in a 'walled
environment'; therefore, we have taken steps to enhance the security of your DNCS.

If your password management and/or user account management is
administered by an external LDAP, RADIUS, or Sudo system, you must manage
your passwords and user accounts on that system and not on the DNCS. For
more information, see Enable RADIUS and LDAP Support in a DBDS for SR 5.0
Configuration Guide (part number 4017610) or contact your system administrator

Purpose
This document contains instructions on changing your security defaults.
We recommend that you keep the operating system defaults to obtain the most
benefit from these security features for your network. However, there may be times
when you might need to change those defaults temporarily; for example, when you
need to troubleshoot or when you need to unlock a user account. This document
contains instructions on many of the DNCS security features. Any changes should be
performed by a DNCS system administrator in collaboration with Cisco personnel so
that your system remains fully functional. The DNCS system administrator should
be well versed in the administration of a Sun/Solaris UNIX platform and must
understand the ramifications of changing the security defaults.
