The way the internet works is continually evolving. There is a growing trend towards secure websites, which increases the chance of your students accessing inappropriate content if extra web filtering measures haven’t been taken. It is important you understand these changes and how they impact your school’s ability to continue providing a safe online environment. Please read the following information and watch the video below. We recommend you discuss it with your IT support person or company, and consider if your current web filtering setup is still adequate.
HTTP vs HTTPS
When you look at website addresses some start with “http” and others with “https”. Most of us don’t pay any attention to this, but the difference is important when it comes to the online safety of your students. Websites that start with “http” are open and subject to the standard keyword filters most schools have as part of their web filtering setup. You can set rules to manage access to these sites, as well as what content on the sites is visible, and what is blocked. Websites that start with “https” are different. They’re called secure websites and they use what are known as ‘secure protocols’ to ensure that, when users access their content, it is secured and private. Google, YouTube, Pinterest and online banking websites are popular examples, but many others are also starting to using these protocols.
What does it mean for your school?
Content on secure websites is not able to be seen or filtered using standard rules and policies, potentially exposing students and staff to inappropriate content. The only way to prevent them from accessing this inappropriate content is to block the entire site, but in many cases this isn’t a suitable option. Currently around 60% of all web traffic across N4L’s Managed Network is via secure websites, and this number is expected to increase dramatically in the near future. As a result, your school’s current web filtering setup may no longer be meeting your needs and should be reviewed, in accordance with your digital citizenship policy. To find out more about this growing trend toward secure websites, and how N4L’s Web Filtering and our new feature “Secure Website Inspection” can help you ensure student safety, please watch this video.
What can you do to protect your students?
The only way for your school to gain visibility of, and to be able to filter content on, secure websites, is to install certificates on devices being used to access the internet. This can be done by implementing Secure Website Inspection as part of N4L’s Web Filtering, work that your school or IT company will need to carry out.
