Believe it or not, manufacturing took over from finance as the most cyber attacked sector in 2021 – almost a quarter of attacks were aimed against them, up from 18% in 2020.
Many attacks are carried out by large and well-funded Organised crime groups supported by state actors. And the West’s overt support for Ukraine in the ongoing war in Europe is only likely to lead to more aggressive attacks as Russia seeks to punish those nations and organisations it believes are frustrating its geo-political ambitions.
The growth in manufacturing’s reliance on Industrial Control Systems (ICS) adds another layer to the problem. ICSs are an integral part of our lives today. They allow for easier management of our most critical infrastructures and processes. Manufacturing, gas, water, power distribution and transportation all depend on ICSs to keep their processes running on a daily basis.
What’s more, the emergence of the Industrial Internet of Things (IIoT) has allowed users to automate some tasks in the process. We can now control everything simultaneously from a remote location, leading to improved workflow efficiency and helping us reach never-before-seen speed and accuracy.
But all of these new technologies have come with increased vulnerabilities that are ruthlessly exploited by cyber attackers – and a growing number of successful attacks will involve an employee within your team.
What are cyber insider threats?
These generally come in two forms.
Malicious – often in the form of a disgruntled fired employee who wants to get back at their former company, though they can also come in the form of employees still working at the company. In that case they may be part of an organised crime network or an individual looking to harm the company through fraud, IT sabotage, intellectual property theft or espionage.
Accidental – in the form of employees who unintentionally expose confidential data through poor cyber hygiene, weak passwords or similar.
Whichever one they are they contribute to a significant number of data beaches every year.
A 2017 report from Clearswift reported that
“Organizations report that 42% of IT security incidents occur as a result of their employees’
In many cases breaches from former employees stem from an organisational failure to identify a change in employee status at the point the employee leaves the company – a classic disconnect between HR and the IT companies that are responsible for data security. Some companies are more vulnerable to this than others – it often occurs where there are high turnovers of staff or where the HR function is outsourced. But IT and HR policies and procedures are key to help companies combat the threat and make it more difficult for Insiders to operate.
What can you do to protect your company?
Threats like these are amongst the most difficult to guard against however there are some key considerations for companies.
Have clear HR policies around staff leaving the organisation and ensure that they are adhered to. All staff leaving to have documented and audited exit interviews to include return of company IT equipment, password cancellations etc., to limit opportunities for former staff members to be able to access company networks. Implement a handover period to try and limit impact on the organisation.
Make staff aware of the approaches that they might get and how to report them. One of Tesla’s employees was approached with a $1M deal for insider access. They reported it, helped with the investigation and a criminal was arrested. The ECRC can provide bespoke staff awareness training tailored to what threats your company and employees might face. Contact us now to find out more.
Implement strong access controls and allow access to systems that people really need rather than everything. If you were working in a physical location, you might have some areas which were only accessible to staff who worked there, and for anything really valuable, maybe a safe. But you wouldn’t give the safe keys to everyone who worked for you. If you’re not sure about access control take a look at one of our short videos about it.
Have internal network logging. This will enable you to see unusual activity - such as thousands of e-mails suddenly being sent outside of the network – this is how General Electric recently suffered a massive data breach. The NCSC has a free tool to help with this, Logging Made Easy. You can read more about it here.
Have policies and procedures which cover data control and access. Consider limiting the number of attachments that could be sent out at once, and then set up a rule which alerts you if any more than that are sent. This gives you the ability to check that what is being sent is going for a legitimate reason. Tell your staff that their emails are being monitored and tell them about the policy. If you are not sure whether your policies cover all that should be considered why not have a policy review with our affordable service provided by one of our students?
Further guidance & support
