Marketing announcements.

For proper interaction of Kaspersky Security Center with external services, consider the following recommendations:
- Unencrypted network traffic must be allowed on ports 443 and 1443 on the network equipment and proxy server of your organization.
- When Administration Server interacts with Kaspersky update servers and Kaspersky Security Network servers, it is necessary to avoid hijacking network traffic with certificate substitution (MITM attacks).

To download updates through the HTTP or HTTPS protocol by using the klscflag utility:

  1. Run the Windows command prompt by using administrator rights, and then change your current directory to the directory with the klscflag utility. The klscflag utility is located in the folder where Administration Server is installed. The default installation path is <Disk>:\Program Files (x86)\Kaspersky Lab\Kaspersky Security Center.
  2. If you want to download updates through the HTTP protocol, run one of the following commands:
    • On the device with Administration Server installed:

      klscflag.exe -fset -pv klserver -s Updater -n DisableKLHttps -t d -v 1

    • On a distribution point:

      klscflag.exe -fset -pv klnagent -s Updater -n DisableKLHttps -t d -v 1

    If you want to download updates through the HTTPS protocol, run one of the following commands:

    • On the device with Administration Server installed:

      klscflag.exe -fset -pv klserver -s Updater -n DisableKLHttps -t d -v 0

    • On a distribution point:

      klscflag.exe -fset -pv klnagent -s Updater -n DisableKLHttps -t d -v 0
