Cyber security for construction businesses

The National Cyber Security Centre (NCSC) partnered with the Chartered Institute of Building (CIOB) to produce this guidance to help small-to-medium sized construction businesses protect themselves from cyber attacks.

Recent high profile cyber attacks against the construction industry illustrate how businesses of all sizes are being targeted by criminals. As the industry continues to embrace and adopt new digital ways of working, it is more important than ever to understand how you might be vulnerable to cyber attacks, and what you can do to protect your business.

This guidance is aimed at small-to-medium sized businesses working in the construction industry and the wider supply chain (including the manufacture of building supplies, surveying, and the sale of buildings).

Whilst we cannot guarantee protection against all the cyber threats you face, by implementing the steps described, you’ll be protected from most common cyber attacks. And should the worst happen, you’ll able to quickly recover.

You can download the guide as a PDF from the bottom of this web page. You're free to print, share, and re-use this document, freely and flexibly, with only a few conditions.
