Keeping Protection Up-to-Date
To illustrate based on the example:
• The ActiveUpdate server has 14 incremental patterns:
173.175 171.175 169.175 167.175 165.175 163.175 161.175
159.175 157.175 155.175 153.175 151.175 149.175 147.175
• The OfficeScan server has 7 incremental patterns:
171.175 169.175 167.175 165.175 163.175 161.175 159.175
• The OfficeScan server downloads an additional 7 incremental patterns:
173.175 157.175 155.175 153.175 151.175 149.175 147.175
• The server now has all the incremental patterns available on the ActiveUpdate

Server Update Methods
Update OfficeScan server components manually or by configuring an update schedule.
To enable the server to deploy the updated components to clients, configure automatic
update settings. If automatic update is disabled, the server downloads the updates but
does not deploy them to the clients. For details, see Automatic Update on page 4-27.
Manual Update
When an update is critical, perform manual update so the server can obtain the updates
immediately. See Manual Update on page 4-20 for details.
Scheduled Update
The OfficeScan server connects to the update source during the scheduled day and time
to obtain the latest components. See Scheduled Update on page 4-19 for details.
Scheduled Update
Configure the OfficeScan server to regularly check its update source and automatically
download any available updates. Because clients normally get updates from the server,
using scheduled update is an easy and effective way of ensuring that protection against
security risks is always current.
