Adding the self-signed certificate as trusted to a browser

The procedures in this section show you how to add the self-signed certificates generated during Kaspersky CyberTrace installation to the trusted storage. This will remove the security warnings generated by browsers.

The information in this section is applicable to the situation when the user gains access to CyberTrace Web from the same computer on which CyberTrace Web runs. If the GUISettings > HTTPServer > ConnectionString element of the Feed Service configuration file refers to an external interface, the CyberTrace Web website will not be considered trusted, because the self-signed certificate can be used only with https://127.0.0.1 and https://localhost addresses.

To avoid potential security risks, it is recommended to use a trusted certificate signed by a certificate authority (CA). For more information, see section "Generating certificates for CyberTrace Web".

Causing a self-signed certificate to be trusted by a browser (CyberTrace Web is opened in Internet Explorer installed on a Windows system)

Gaining the browser's trust requires that you perform, in sequence, the following three procedures:

To save the certificate to a local file:

  1. Open the https://127.0.0.1 or https://localhost address in Internet Explorer.

    The browser informs you of a problem with the security certificate of the website.

  2. Select the Continue to this website (not recommended) link.

    The Certificate Error message appears in the address bar.

  3. Click Certificate Error.

    The Untrusted Certificate window opens.

  6. Follow the Wizard instructions.

    Use the default Wizard settings during the certificate export.

To start the certificate import process through Microsoft Management Console (MMC):

  1. From the Search box, navigate to the Run box and enter mmc.

    You can now run MMC as Administrator.

Causing a self-signed certificate to be trusted by a browser (CyberTrace Web opens in Google Chrome installed on Windows system)

To make the self-signed certificate for CyberTrace Web trusted when using Google Chrome:

  1. Open the https://127.0.0.1 or https://localhost address in Google Chrome.

    A warning is displayed in the address bar that the connection to the site is not secure.

  2. Click the Not secure message.

    A window opens with security details about the website.

  3. Click Certificate to view the certificate information. (When the mouse pauses over Certificate, a Show certificate tooltip appears.)
  4. In the Certificate window that opens, select the Details tab and click Copy to File to create a local copy of the certificate.

    The Certificate Export Wizard starts.

  6. After the certificate is saved to a local disk, open it and add it to the Trusted Root Certification Authorities store as described in the procedure for Internet Explorer.
  7. Restart the browser.

Causing a self-signed certificate to be trusted by a browser (CyberTrace Web opens in Mozilla Firefox)

You add CyberTrace Web to the list of Mozilla Firefox trusted sites so that the browser will not display warnings about the certificate.

Causing a self-signed certificate to be trusted by a browser (CyberTrace Web opens in a browser for Linux)

Procedures for using a browser to import a certificate as trusted (on Linux systems) vary depending on the browser and Linux distribution used. But the procedures share common steps: to open the browser settings form and use the form to import the certificate to a store.

To manually cause a self-signed certificate to be trusted by a browser on a Linux system:

  1. Create a /usr/local/share/ca-certificates/ directory if it does not exist on your computer:

    mkdir /usr/local/share/ca-certificates/

  2. Copy your root certificate (.crt file) to the created directory:

    cp <full path to the certificate> /usr/local/share/ca-certificates/

  3. Update the certificates:

    sudo update-ca-certificates

    If you do not have the ca-certificates package, install it with your package manager.

Removing a certificate from the list of trusted ones

After you have reconfigured or uninstalled CyberTrace, old certificates are no longer used by CyberTrace. You can remove them from the list of trusted certificates.

To remove a certificate from the list of trusted certificates (on Windows):

  1. Open the Certificates management console by running the following command:

    certmgr.msc

  2. In the tree pane, select Trusted Root Certification Authorities > Certificates.

    Certificates management console

  3. In the results pane, right-click the added certificate and select Delete.

On a Linux system, the removal procedure is performed in a way that is similar to the addition of a certificate: open the list of the trusted certificates and remove those that you do not need.
