A user visits a trusted website. The website sends the user a link via email to the default browser window. When the user clicks on the link, a message appears stating that there is a problem with the website’s security certificate. Why has this occurred?
- the browser has identified it as a malware
- the antivirus has flagged this as a known virus
- the pop-up windows on the browser have been disabled
- the CRLs of the browser have not been updated
| Explanation & Hint:
Certificate authorities (CAs) issue certificates to domains that contain a public key so that the CA that issued the certificate can validate it because they signed it. The browser can provide the information associated with the certificate when a site is using HTTPS. A certificate error can be addressed by updating the certificate store for the respective browser. |
