The Trouble with App-Blocking for Schools
Apps, short for “applications,” come in both downloadable and web-based forms. Your own phone is likely running apps of both kinds, from its web-based Facebook app to its native Camera app. Students are more likely to abuse web-based applications simply because most schools are already adequately preventing them from downloading unapproved native apps to their phones or devices using firewalls.
Web-based applications pose a significant challenge for web filtering technologies because they’re incredibly nimble. Savvy students know how to migrate whole web-based applications to a new URL once they’re identified by school filters; this creates a never-ending game of cat and mouse for administrators using traditional web filtering software.
Apps, unlike websites, tend to run on languages uniquely their own, known as “protocols.” Traditional school filters can’t always translate new and emerging app protocols which allow many apps to circumvent first-level blocking attempts.
Additionally, apps also run on different ports than web content, creating an additional layer of necessary monitoring for ad-hoc filters. When school filtering technology uses list-based blocking, innovative students can easily stay one step ahead.
The solution? Comprehensive network filtering with Smoothwall Filter.
App-Blocking Solutions for Schools
Smoothwall’s complex filtering system blocks distracting apps in a number of ways. On a base level, students are always prohibited from downloading unapproved apps directly onto their devices whether they are BYOD or school-issued thanks to firewalls.
From there, Smoothwall’s blocking capabilities can be configured to block specific ports (such as the ports used for common student apps like Snapchat) and also to block unique protocols that are known to the school to be unacceptable. But from there, it’s Smoothwall’s revolutionary Content Aware filtering technology that enables truly comprehensive app blocking.
Smoothwall’s Content Aware filtering actively assesses the content, context and construction on each page of a web-based application in real time. A gaming app running off a brand-new circumvention protocol, for example, would be blocked based on its content, not on its unsuspicious protocol language. Similarly, apps running through seemingly benign ports would also be blocked before loading for students by the measure of their content, not the pathway students used to access them.
It’s important to remember that some applications live on URLs that schools don’t want to block. Google Sites, for example, is home to one of the most robust networks of custom-created student distraction apps on the Web. Traditional URL filters wouldn’t block access to a www.Google.com URL because students need access to perform search queries. Smoothwall’s granular content-aware filtering, however, blocks access to Google Sites apps based on the content of their pages (i.e. Angry Birds: Blocked), not their Google.com URLs.
Smoothwall’s app blocking technologies help keep students productive and on task. Web-based apps are just the latest in the long history of students circumventing content blockers online. Content-Aware filtering is a solution with staying power.
