Sometimes the customers need to add more than one Service User in Symantec Web Security Service (WSS). The use of one credential shared by more than one administrator is a security risk. Symantec recommends the use of Service User depending on the role needed. In that way, the Global Admin can control/trace the access and tasks made by those users in portal.threatpulse.com without sharing his credentials.
The Symantec Web Security Service allows Admin Users to add other user access to the portal and assign them privileges based on their role in the organization. Currently, there are three available roles.
Only Admin Users can modify other Symantec Web Security Service users. For example, change the default role or temporarily disable a user's access. Also, Web Security Service Administrative Users are able to disable any provisioned user regardless of any use of a personal password.
Symantec strongly recommends limiting the number of Web Security Service users with administrative credentials. Depending on the size and complexity of your organization, you might have more than one user administering the different services (Content Filtering, Threat Protection, Web Application Controls) or possibly a user responsible different geographical locations. No matter how many Admin Role users exist, there is only one policy per Web Security Service customer account. If more than one administrator alters policy, they might unknowingly change policy created by another user. Have clear administration solution goals to minimize this possibility.
