Two steps you should take to protect your network from hackers

Passwords are not enough: How to turn on two-factor authentication
Two-factor authentication is no longer an optional feature. If you use modern cloud services, this extra layer of security can dramatically reduce the risk of a hostile takeover. Here’s how to get started.

A former director of the UK’s secret intelligence service has offered advice on what organisations can do to help stay protected against cyber attacks.

Speaking at the Digital Transformation Expo Europe in London, ex-MI6 chief John Sawers touched on the various threats facing the UK and other countries right now, including cyber attacks by and espionage by both criminals and nation states – but told the audience there are some key things which can be done to help organisations and their employees from becoming victims.

First of all, organisations should be employing two-factor authentication; something that is relatively simple to rollout.

“If you’re not using two factor authentication, you’re well behind the game and much more vulnerable. That’s the first thing individuals can do,” said Sawers, who served as head of MI6 between 2009 and 2014.

Businesses should ensure they’re running modern cyber defences with protections against malicious activity inside the network, rather than just relying on firewalls and the like to keep threats out. If attackers breach that perimeter and there are no internal defences then things can go bad quickly, as demonstrated by the NotPetya incident of summer 2017.

“The companies that got hit by the NotPetya virus two years ago were the ones which had an old fortress-and-moat system where they had external defences around their IT system and free movement within it,” Sawers said. “That simply doesn’t work for modern cyber security systems.”

To stay protected against modern cyber attacks, he argued that an organisation needs multi-layer protection throughout the network and to determine the risk category of the information or data stored.

“You’ve got to be able to identify your crown jewels and have them completely protected, you’ve got some material that’s going to be at risk and you’ve got some material you know is going to be vulnerable,” he explained, adding “knowing what others want from you and what you have to protect for your own future is absolutely vital.”

Sawers also touched upon the security debate around Chinese telecommunications provider Huawei. While the US has indicated it will not use Huawei technology in its infrastructure, the UK has so far taken a more flexible approach.

Some have voiced concerns about Huawei posing a cybersecurity risk to UK infrastructure, but Sawers is less concerned.

“I think the founders of Huawei and the Chinese government sees Huawei as a major Chinese commercial entity, rather than an arm of the state,” he told ZDNet, before adding there would be “very serious consequences” if it did abuse its position as a UK supplier.

But he said: “We’ve not, in the 20 years that we’ve had Huawei equipment  in our system, experienced it being used by the Chinese state for espionage purposes – we see a lot of Chinese espionage efforts here in the UK and across the west, but they haven’t sought or been able to exploit Huawei equipment for that purpose,” said Sawers.

While Sawers did detail how there’s an espionage threat which needs to be managed, it can be mitigated without excluding Chinese manufacturers from the market, for example by keeping such hardware to the edge of the network. “The fact we can control it, largely at the periphery, means there are much better defences in place,” he said.
