UK Cyber Security Council

Cyber security is a practical field - but it can also be technical. And, with technical, comes the need from time to time to use technical terms, whose meanings non-technical people might not immediately grasp. The thing is, though, you often need to use technical terms – after all, your reports to the executive team and the board will be the size of War and Peace if you have to keep writing things like “device that filters traffic between two networks” or “A mechanism whereby the network infrastructure forbids a device from communicating until it has proven its identity” rather than “firewall” and NAC respectively.

The UK Cyber Security Council has assembled a definitive glossary of cyber security terms, as a path to their de-mystification. So while cyber awareness training has probably told everyone reading this that “phishing” means “Sending fake emails to people purporting to be someone they know or someone senior at their workplace”, it’s less common for non-techies to know that a PRNG is a pseudo-random number generator “that generates numbers that are almost random”, or that an RPO – restore point objective – is the point in time to which the data on a system must be recovered in the case of a data loss.

Over the next few weeks, for Cyber Security Awareness Month, we'll be highlighting the definitions of 20 or so terms on social media, to give a leg-up for readers with the definitions of common terms. The full glossary, with over 370 definitions, is here.
