New internet security device launched to safeguard schools against child abuse

Computer experts at the University of Plymouth have created a new device that provides round-the-clock monitoring against online child abuse and radicalisation for primary and secondary schools.

ICAlert plugs straight into a school's network, checks all web traffic, and immediately generates an alert if there is any attempted access of illegal material, such as images, terrorist material or extremism websites.

The University is now working with South West Grid for Learning (SWGfL) and the Internet Watch Foundation (IWF) to offer the safeguarding service for schools across the region, and SWGfL has seconded specialist police officers with extensive experience at handling child pornography offences to be the points-of-contact.

The technology has been developed by academics within the School of Computing, Electronics and Mathematics. Bogdan Ghita, Associate Professor of Computer Networks, co-led the project with Paul Dowland, until recently Associate Professor of Information Systems Security, now of Edith Cowan University, Perth, Australia.

Bogdan said:

"The challenge was to encapsulate the service offered by SWGfL in a self-contained, reliable and affordable box that required minimal set up and no input thereafter. The resulting solution brings together hardware that connects seamlessly into a school's network infrastructure, with efficient software that delivers the required analysis. ICAlert offers long-term, effective monitoring of a school's network and is flexible enough to deal with increasing or number of users."

The low-cost devices are supported by the Counter Terrorism Internet Referral Unit (CTIRU) and manufactured by Cornwall firm Selectronics Limited. Once plugged into a school's network, the device is ready to use and requires no additional management by the school. The tool receives periodic updates that include the latest list of banned web content links, as published by the Internet Watch Foundation, in an encrypted format. It is against this list that ICAlert compares internet traffic at the school.

The team say it provides an alternative solution to 'filtering', where access to banned sites is simply denied and the attempt to perpetrate an offence goes unnoticed.

South West Grid for Learning (SWGfL), and the Internet Watch Foundation (IWF) under a Home Office regulated project, have been piloting this alerting capability (for illegal content) with its connected schools since 2006.

David Wright, Chief Executive at SWGFL, said:

"Over this period there have been a number of alerts that have led to successful prosecutions and the removal of potential threats to children and wider school communities. This is something that SWGfL is particularly proud of, and ICAlert now extends this alerting capability to any school – firstly in the region and potentially nationally thereafter."
