Interpreting a browser’s visual clues about security

The continuous drumbeat of news about pervasive surveillance, security breaches, identity theft, malware, phishing and so forth has had at least one salutary effect on our interactions on the web. The general public is increasingly aware of the need for safe browsing habits, such as not clicking on unknown links in webmail, hovering your cursor over hyperlinks to see if you recognize the URL revealed, and, above all, to “Look for the Lock”.

Such mnemonics and visual aids are important ways to communicate security features to end users, allowing them to take informed decisions on what level of trust they should expect during a particular instance of communications on the web. This post will concentrate on these visual indicators, in particular how browsers represent the identity of the server/site with which an end user would like to interact. The SSL/TLS certificate that the server presents to the browser at the start of the communications is the information source which the browser uses to create the appropriate visual representation that guides the user. Readers would do well to brush up their knowledge on the different types of certificates that are available by reading our previous posts on the subject, as what follows will assume that the reader is aware (at least at a high level) of their basic properties and differences.

Most people are now aware of the need to look for the https://….. in the browser address bar as well as the lock symbol accompanying it. This is the part of the screen that is controlled purely by the browser, which populates it with the site URL and other security information gathered from the SSL/TLS certificate used to secure the connection.

For instance, look at the images below of the luxsci.com website as shown in the address bar of Google’s Chrome, Microsoft’s Internet Explorer (IE), Mozilla’s Firefox and Microsoft’s Edge browsers.
