Trusted Certificate Authority Change Logs


  • Click 'Tasks' > 'Advanced Tasks' > 'View Logs'

OR

  • Click ‘Logs’ in advanced view of the CIS home screen
  • Select 'Trusted Certificate Authorities Changes' from the drop-down at upper-left.

Root certificates are a critical part of online security. Your internet browser relies on them to verify that you are connected to the site you think you are connected to.


If a fake root certificate was to find its way into your browser's trusted certificate store (TCS), then you could be tricked into connecting to a fraudulent server instead of the site you intended.


Comodo Internet Security checks the trust rating of all root certificates in your browser's TCS to ensure they are legitimate. It runs this check during the following scans:

  • Rating scan - Click 'Scan' > 'Rating Scan'
  • Full scan - Click 'Scan' > 'Full Scan'
  • Custom scan profiles that include the certificate store. Click 'Scan' > 'Custom Scan' > 'More Scan Options'
  • Unrecognized and self-signed certificates are marked as 'Untrusted'.
  • You can choose to trust the certificate or remove it. An example is shown below:


  • Clean - Removes the certificate from the store
  • Trust - Assigns 'Trusted' status to the certificate. The certificate is excluded from future scans.
  • No Action - The certificate keeps its untrusted status, but is not deleted.
  • Any changes to the certificate store are logged in 'Trusted Certificate Authorities Changes'.


Background:

There are two types of certificate involved when you connect to a secure website:

  1. Website SSL certificate – These certificates are hosted on the website you connect to. They are used to encrypt the connection between your browser and the site. This is especially important for sensitive transactions like online payments, where you send your credit card information over the internet.

  2. Root certificate – These certificates are embedded into your browser (Chrome, Firefox etc). They are used to validate that the website's SSL certificate (above) is genuine – that it has been issued by a trusted certificate authority.

  • You can tell a site is using an SSL certificate by the padlock icon in the browser address bar. You will also notice that the website address begins with https:// (the 's' stands for 'secure').
  • Website SSL certificates are issued to site owners by an organization known as a 'Certificate Authority' (CA). The CA checks that the website owner is a legitimate business before they will issue a certificate to them.
  • When you connect, your browser checks that the SSL certificate on a site is signed by root certificate from a trusted CA.
  • If a fake root certificate got embedded into your browser, it could tell you trust a website run by a hacker.
  • CIS detects whether you have any fake root certificates in your browser when you run a rating scan, a full scan, or a custom scan (if so configured).
