About Kaspersky Security Center certificates

Kaspersky Security Center uses the following types of certificates to enable a secure interaction between the application components:

By default, Kaspersky Security Center uses self-signed certificates (that is, issued by Kaspersky Security Center itself), but you can replace them with custom certificates to better meet the requirements of your organization's network and comply with the security standards. After Administration Server verifies whether a custom certificate meets all applicable requirements, this certificate assumes the same functional scope as a self-signed certificate. The only difference is that a custom certificate is not reissued automatically upon expiration. You replace certificates with custom ones by means of the klsetsrvcert utility or through the Administration Server properties section in Administration Console, depending on the certificate type. The indexes of the certificate types described below are based on the possible values of the -t certtype parameter in the klsetsrvcert utility:

Administration Server certificates

An Administration Server certificate is required for authentication of Administration Server, as well as for secure interaction between Administration Server and Network Agent on managed devices. When you connect Administration Console to Administration Server for the first time, you are prompted to confirm the use of the current Administration Server certificate. Such confirmation is also required every time the Administration Server certificate is replaced, after every reinstallation of Administration Server, and when connecting a slave Administration Server to the master Administration Server. This certificate is called common ("C").

Also, a common reserve ("CR") certificate exists. Kaspersky Security Center automatically generates this certificate 90 days before the expiration of the common certificate. The common reserve certificate is subsequently used for seamless replacement of the Administration Server certificate. When the common certificate is about to expire, the common reserve certificate is used to maintain the connection with Network Agent instances installed on managed devices. With this purpose, the common reserve certificate automatically becomes the new common certificate 24 hours before the old common certificate expires.

You can also back up the Administration Server certificate separately from other Administration Server settings in order to move Administration Server from one device to another without data loss.

Mobile certificates

A mobile certificate ("M") is required for authentication of the Administration Server on mobile devices. You configure the use of the mobile certificate on the dedicated step of the Quick Start Wizard.

Also, a mobile reserve ("MR") certificate exists: it is used for seamless replacement of the mobile certificate. When the mobile certificate is about to expire, the mobile reserve certificate is used to maintain the connection with Network Agent instances installed on managed mobile devices. With this purpose, the mobile reserve certificate automatically becomes the new mobile certificate 24 hours before the old mobile certificate expires.

If the connection scenario requires the use of a client certificate on mobile devices (connection involving two-way SSL authentication), you generate those certificates by means of the certificate authority for auto-generated user certificates ("MCA"). Also, the Quick Start Wizard enables you to start using custom client certificates issued by a different certification authority, while integration with the domain Public Key Infrastructure (PKI) of your organization enables you to issue client certificates by means of your domain certification authority.

iOS MDM Server certificate

An iOS MDM Server certificate is required for authentication of Administration Server on mobile devices running the iOS operating system. The interaction with these devices is performed via the Apple mobile device management (MDM) protocol that involves no Network Agent. Instead, you install a special iOS MDM profile, containing a client certificate, on each device, to ensure two-way SSL authentication.

Also, the Quick Start Wizard enables you to start using custom client certificates issued by a different certification authority, while integration with the domain Public Key Infrastructure (PKI) of your organization enables you to issue client certificates by means of your domain certification authority.

Client certificates are transmitted to iOS devices when you download those iOS MDM profiles. Each iOS MDM Server client certificate is unique. You generate all iOS MDM Server client certificates by means of the certification authority for auto-generated user certificates ("MCA").

Web Server certificate

A special type of certificate is used by Web Server, a component of Kaspersky Security Center Administration Server. This certificate is required for publishing Network Agent installation packages that you subsequently download to managed devices, as well as for publishing iOS MDM profiles, iOS apps, and Kaspersky Endpoint Security for Mobile installation packages. For this purpose, Web Server can use various certificates.

If the mobile device support is disabled, Web Server uses one of the following certificates, in order of priority:

  1. Custom Web Server certificate that you specified manually by means of Administration Console
  2. Common Administration Server certificate ("C")

If the mobile device support is enabled, Web Server uses one of the following certificates, in order of priority:

  1. Custom Web Server certificate that you specified manually by means of Administration Console
  2. Custom mobile certificate
  3. Self-signed mobile certificate ("M")
  4. Common Administration Server certificate ("C")
