It is a timely reminder that schools should be ever vigilant when it comes to hacking and phishing attacks, and the need to report serious data breaches to the ICO and to make data subjects aware of the potential threat to their data.
If you are worried about whether or not your school is vulnerable you need to ensure you seek appropriate advice, both from IT specialists to ensure your systems are adequately protected, and from data protection consultants such as myself to ensure you know how to react should a data breach occur.
Don't leave it until something happens - put things in place now and be prepared!!
