The Government does not censor or interfere with legal content online. If online content is deemed illegal, it is a matter for law enforcement to investigate.
However, cyber security is a top priority for the Government. We are investing £1.9 billion in the national cyber security strategy and have opened the National Cyber Security Centre which is working with public and private sector organisations to make the UK the safest place for online activity.
All organisations should have good basic cyber security measures in place, such as the Government's Cyber Essentials scheme, which protects against common vulnerabilities, which are widely reported online, and will not be specific to schools. They should also ensure they have appropriate protections in place for sensitive data such as personal details.
