Hello,
Yes, they are same.
System Lockdown allows administrators to tightly control which applications users running the SEP Client can execute. The approved applications are contained in a so-called fingerprint list which contains checksums and locations of all applications that are approved for use.
Implementing System Lockdown is a two step process. First, a fingerprint list needs to be created, and then this fingerprint list needs to be imported into the Symantec Endpoint Protection Manager for use in Client Policies.
To generate the file fingerprint list, a tool is included in the Symantec Endpoint Protection Client installation. We recommend to create a software image that includes all of the applications you want users to be able to use on their computers, and to use this image to create a file fingerprint list.
