Hello,
What are the sizes of the various packages that are sent between the Symantec Endpoint Protection client and manager?
The following are estimates of the size of packages that are sent between the Symantec Endpoint Protection client and manager:
Heartbeat (with no updates to be exchanged) - When there is no traffic to be exchanged (i.e. no profile to download and no logs to update) then the heartbeat is between 2 KB/s and 3 KB/s.
Policies (i.e. AV/AS, Firewall, OS Protection, Host Integrity) - Typically varies between 20 KB and 80 KB, but can increase if detailed rules are included, or OS protection templates are used. Generally, after you set your policies to suit your network needs, you do not modify them on a regular basis.
IPS Signature Updates - Files range between 50 KB and 100 KB. Symantec supplies updates approximately every quarter unless a specific threat or vulnerability needs to be addressed.
AV Signatures - 50 KB to 100 KB daily for clients, if you assume that the signatures are updated successfully every day.
Logs - Logs are compressed at the client before they are uploaded to the Symantec Endpoint Protection Manager.
Approximately, 800 log entries take up 1KB of file space.
