Best Practice: Schedule an IPS Update
Check Point’s global Research and Response Centers provide regular updates to ensure you have the most up-to-date defenses to protect you from the latest exploits, but if the update isn’t installed, you’re not protected. In R71 you can configure a schedule to download and install IPS protections reducing the time that your systems are vulnerable to threats.

To schedule IPS updates:
  1. In the IPS tab, select Download Updates and click Scheduled Update
  2. Select Enable IPS scheduled update
  3. Click Edit Schedule to create a schedule for the updates
    1. In the Scheduled Event Properties window enter the name of the schedule and the time of the update. Choose either;
      • a specific time
      • or a time interval like every 12 hours
  4. Click User Center credentials to enter your User Center credentials
  5. Enable On Successful update perform Install Policy
The resulting schedule is shown in the Scheduled Update window.
