A HTTPS content filtering solution is a tool that filters the content of “secure” websites in addition to “regular” websites. “Secure” sites are those authenticated by a Certificate Authority as being genuine and whose URL begins with https://. When you navigate to a “secure” website, the conversation between your web browser and the website is encrypted to protect against eavesdropping, tampering with, or forging the contents of the conversation.
Originally used for secure transactions such as online banking, over the past decade more and more sites have been changing to HTTPS. In order to keep user conversations private, even social media sites have adopted secure connections. However, mirroring the growth of HTTPS websites, there has been a growth of fake HTTPS websites. Cybercriminals can obtain SSL certificates for free simply by verifying ownership of the domain. The SSL certificate is obtained before any malicious content is used on the domain.
Consequently, a “standard” Internet filter is not sufficient to ensure your Internet users are exchanging information with genuine websites. Although Internet filters can be configured to block access to every HTTPS website except those you explicitly allow, it is far safer to only implement Internet filters with SSL inspection – filters that decrypt the content of the website, inspect it, and then re-encrypt it before allowing access. With HTTPS web filtering, users can access any website that does not contravene your acceptable Internet usage policies. Businesses that do not have a content filtering firewall can easily implement a hardware or software-based standalone HTTPS URL filtering solution.
Benefits of Internet Filters with SSL Inspection
In addition to adding strength to an organization´s online security defenses, there are other benefits of Internet filters with SSL inspection. By implementing a HTTPS content filtering solution with SSL inspection, system administrators can choose to block or allow access to certain applications within a website.
Using solutions to filter HTTPS traffic that have SSL inspection capabilities, administrators can block access to applications such as Facebook Chat and Facebook Sharing while allowing access to the rest of your organization´s Facebook page. The same process could be applied to Twitter, Google Apps and any other vehicle used to promote your business, but which you would not want your employees using for private conversations during work.
Internet filters with SSL inspection can also identify HTTPS websites containing inappropriate content in encrypted format that might otherwise be missed by a “standard” web content filtering solution. This means that access to websites containing pornography or racial hatred will be blocked by a HTTPS content filtering solution with SSL inspection rather than being allowed through by a “standard” web content filtering solution because its category or keyword filters have been unable to find any prohibited material on the site.
Avoid CPU Strain with Whitelisting
There is a known issue with Internet filters with SSL inspection. The resources required to decrypt, inspect and re-encrypt every encrypted website can place a significant strain on CPUs during times of peak Internet activity. This in turn reduces Internet speeds, can affect access to emails and negatively affects network performance in general. Fortunately there is a simple solution to overcome this common SSL filtering problem – whitelisting.
Whitelisting is a process in which the URLs of the most frequently accessed websites are entered into the HTTPS content filtering solution. This allows the websites to bypass the SSL content filtering mechanisms, reducing the volume of SSL inspection required and reducing latency. Most businesses will only need to enter a handful of trusted websites into the HTTPS content filtering solution in order to avoid CPU strain, so implementing the whitelisting solution should be quick and easy. Care should be taken, as when whitelisted, HTTPS content filtering will not take place. Whitelisting should therefore only be used on 10% trusted websites.
In addition to being able to whitelist trusted websites, it is also possible to whitelist trusted apps and apply the whitelisting of these apps to specific users or user groups. Whitelisting can be a quicker and easier alternative to creating exemptions from Acceptable Use Policies if, for example, you wanted to provide certain executives with access to the Skype instant messaging app.
