Three steps to cloud security

The average time between a cyber security breach and its detection is 229 days. Manufacturing facilities are leading the list of potential targets for cyber espionage, denial of service (DoS) and web-application attacks. Here, Martyn Williams, Managing Director of industrial automation software supplier, COPA-DATA UK, discusses three steps manufacturers should take to stay safe in the cloud.

As the manufacturing sector moves towards industrial automation, the Internet of Things (IoT) and the cloud, the number and nature of cyber threats is also growing.

Hackers used target the IT and enterprise systems, but now manufacturers are seeing the same threats on their production lines, sensors, PLCs and SCADA systems. Traditional security focused on passive defence, but increasingly advanced attacks require a different approach.

The one thing manufacturers need to understand is that any industrial automation system today is vulnerable to cyber attacks. The only way of taking advantage of the benefits of IoT and the cloud is to stay vigilant and use industry best practice. Industrial security is no longer the IT department’s concern, but a 24/7 job for everyone, including those in the boardroom.

Identify and protect valuable data

From intellectual property (IP) to trade secrets or critical production data, most departments in your organisation have sensitive information that could be the target of cyber-attacks. The first step is to identify these valuable data assets and restrict access to them by “hiding” them behind additional layers of protection and encryption.

Manufacturers can protect valuable production data using industrial automation software that has comprehensive security features, such as strong encryption, secure user administration and digital file signatures to recognise bogus programmes. Software that allows you to allocate password-protected access to individual users is particularly beneficial because it empowers manufacturers to create individually configured access levels for different users. This means only authorised users gain access to valuable information.

Best practice

One of the biggest concerns many people have about cloud computing is that once data is in the cloud, it can be accessed by unauthorised users with malicious intentions. However, there is a significant distinction to be made. Validated software and cloud computing providers help ensure that their cloud is protected at the physical, network, application and data layers so that their services are as resilient to attack as possible and client data remains safe.

The problem arises when users store or access company data through alternative devices or consumer cloud solutions. The most common ones are personal smart phones, tablets or e-mail addresses.

Bring Your Own Device (BYOD) was an industry trend 5 years ago – today it is a reality. Employees everywhere use their own devices to access work e-mails, remote monitoring applications, CAD designs and other sensitive information. Unfortunately, this practice exponentially multiplies the risks of a cyber attack.

Industry standards

Slowly, but surely, industry is starting to outline and implement cyber security standards to make industrial networks, devices, software, processes and data more secure. For example, the NIST Cyber Security Framework published in the US compiles leading practices from several standard bodies. There is no such thing as a foolproof formula, but NIST is a good place to start.

For Industrial Automation and Control Systems (IACS), IEC-62443 offers industry guidance that allows end users, systems integrators, security practitioners and the designers and manufacturers of industrial automation and control systems to work to the same standards. This results in a comprehensive and secure hardware and software system — the basis of any cyber-secure manufacturing facility.

Although cyber security in today’s connected factory is never 100% secure, best practice helps manufacturers detect threats early and address them in an effective way. This means an industrial security system will be able to spot intruders early rather than after 200 odd days when it might just be too late.
