The national security strategy has been announced today, listing cyber warfare as the second most prominent threat to Britain.

With cybercrime now ranking as Britain’s second biggest threat, it is no surprise that investment has been bolstered. But, how much of a difference will the money really make, if Government departments are going to have to cut back on people and IT spend?

Cyber techniques morph, adapt and regularly sneak past traditional computer defences, making it difficult for security defences to keep the bad guys out. It is important that every penny invested in new techniques to fight cyber warfare is made to count. To do this, Government departments will need to be provided with the right guidance over their risk priorities.

A successful cyber terrorist attack will interfere with critical infrastructure. It might be taking down a communication system during a national emergency or disrupting the supply of power and water across the country. Cyber warfare is real. Just look at the Stuxnet attack to realise the reality of such attacks and the sophistication of the new battleground for global warfare.

To protect critical infrastructure, organisations needs to switch from allowing everything in until it is proved to be bad to preventing anything from coming in unless it is proved to be good. With cyber criminals becoming ever more sophisticated, it’s now up to those at the very top of the coalition government to ensure that the UK doesn’t fall victim to a cyber attack.
