Hi Technical, Brian and Pete,
I appreciate your responce on this but try to understand that the answer are not correct as per query.
I have read page no 65 and also refer the above links so I can say that When upgrading, Symantec Endpoint Protection (SEP) shows tamper protection alerts when edpa.exe restarts in the presence of the Symantec ManagementAgent.In such case EDPA are added in exception as per below to run edpa & wdp services.
Add edpa.exe and cui.exe to the SEP tamper protection
exception list. Use the following steps:
1. Log in to SEPM.
2. Go to Policies.
3. Under view policies click Centralized Exception.
4. ClickAdd a Centralized Exception Policy.
5. Click Centralized Exceptions.
6.AddTemper Protection Exception.
7. Enter the full path location of edpa.exe.
8.Repeat steps 1–7 to add cui.exe to the Exception List.
9. Save the new policy.
10.Assign the new policy to the client group.
Note: This workaround is only applicable for managed SEP
clients only. Currently,there is no solution for unmanaged
SEP clients.
