Cyber-Physical Attacks: Assessing the Global Security Implications

Cyber-physical attacks target physical systems and have severe consequences for your digital and physical systems. From compromising money and personal information to disrupting your physical infrastructure, these attacks can cause much harm if not stopped. 

To prevent these attacks, you need to first understand the way they function and their types. By implementing effective strategies, organizations can easily minimize the risks. 

In this article, I’ll explain the term, explore the types of cyber-physical attacks, and discuss the working procedures and prevention strategies. 

What are Cyber-Physical Attacks?

Cyber-physical attacks are the type of attacks that target physical systems like factories, traffic control systems, treatment facilities, and more to gain unauthorized access to systems or data. The primary aim of this is to cause damage and disrupt the functions of physical systems.

Cyber attackers breach computer systems and hack the connected physical world to perform an action that can cause physical consequences. They do this to exploit the control of assets and get financial gain. With the increase of connected IoT devices, hacker finds it easy to compromise the most vulnerable devices first and then go through each connected device through the data path. This results in disabling more and more devices in the IoT network. 

If we dive into some of the cyber-physical attacks in history, we’ll find that many government organizations, companies, and others faced such attacks. The hackers or attackers first hack the main computer system by email phishing, viruses, malware, etc., and then exploit the physical items connected to it. 

Real-Life Examples of Recent Cyber-Physical Attacks

• In 2021, there was an attack by a hacker on a water treatment plant situated in Florida to disrupt the available systems and create chaos among them. 
• In 2008, attackers targeted railway organizations by derailing four tram-trains in Poland. 
• In 2017, there was a Triton attack where the attacker targeted safety instruments that are used in industrial environments to protect workers’ lives and the ecosystem. 
• In 2015, there was a Ukrainian power grid attack that was held in multiple stages to outage the power supply for all consumers. 

Types of Cyber-Physical Attacks

Six types of cyber-physical attacks are divided according to their nature of attacks.

• Zero-Day Attacks: They aim at your organization’s security with a high probability of your business downtime. It hasn’t been publicly disclosed yet, and therefore, only a few businesses can catch this kind of vulnerability. The result of a zero-day attack could be disastrous for an organization. It installs powerful malicious software within your system that directly prevents you from installing security patches to disable the attack. 
• Side-Channel Attacks: These refer to the illegal way of collecting data through industrial equipment. Here, attackers gather sensitive data on your working equipment by noting the fluctuations in your power usage during data processing. 
• Denial of Service Attacks: These attacks are common and often bring down systems through unwanted requests. This attack prevents you from accessing computational resources so that the targeted systems fall under the control of hackers. 
• Replay Attacks: There are harmful attacks that target electronic equipment through data packets. They transmit a proven data packet with hidden malicious instructions that appear to come from a legitimate origin. 
• Eavesdropping attacks: They are very common attacks that gain access to your sensitive information illegally. These attacks are carried forward by attacking on communication channels used by organizations or individuals to share important data. 

How Does Cyber-Physical Attacks Work?

The primary aim of cyber-physical attacks in cybersecurity is to exploit your physical and digital systems by using various techniques. To do so, they penetrate insecure networks, manipulate hardware weaknesses, infiltrate malicious code into your system software, and more. 

Once attackers get the entry point to your systems, they can exploit network, hardware, physical devices, and software. This means a single loophole in your security can cause a highly vulnerable situation. 

How to Prevent Cyber-Physical Attacks?

Cyber-physical attacks comprise a wide range of methods that can easily exploit physical domains, primarily three essential components – network, software, and hardware. 

But, everything has a cure. You will require a heterogeneous approach to prevent and stop them. An average security plan for your business or financial institution includes 

• Risk assessments
• Use of advanced technologies
• Compliance services
• Information sharing
• Employee training
• Security frameworks 

Let’s discuss each of the measures to understand how they can help you secure your physical systems from cyber attacks. 

Risk Assessments

Not all types of cyber-physical attacks are hard to detect. Some are very common and can be detected easily when you operate the risk management process continuously in your organization. Cyber attackers change their strategies constantly, so it is necessary to assess the risks regularly to detect the attack prior to its entry in your physical systems. 

Use of Advanced Technologies

You can use advanced analytics, machine learning, and artificial intelligence to detect threats and respond faster during cyber-physical attacks. These cutting-edge technologies provide real-time insights and analysis reports, letting your security systems target threats accurately and quickly. 

Compliance Services

Compliance services play a major role in ensuring security systems, complying with the law, and keeping data secure. The right solutions in your digital security systems help detect vulnerabilities in defense systems, integrate digital and physical solutions, manage supply chain and vendor security, create security trails, carry out penetration testing, and more. 

Information Sharing

Information sharing or collaborating with other businesses helps you mitigate the risks of cyber-physical attacks. Some businesses already face the risks and are preventing them. Discussing with them enables you to learn their techniques and implement them in your security systems. 

Employee Training

Spread awareness about security breaches by educating your employees about advanced methods, engineering tactics, and other possible prevention techniques. Managers need to take the responsibility of giving training on baiting, pretexting, and phishing so that employees can recognize threats through emails, requests, or links and prevent them. On the other hand, managers segregate the duties among the employees to ensure secure access to the data.

Security Frameworks

Businesses and financial institutions need to work on integrating and unifying security protocols to fight against attacks. Security frameworks are the backbone of your effective security strategy. Digital measures like intrusion detection, firewalls, and encryption work best when unified with access control protocols, biometric systems, and surveillance cameras. 

Conclusion

Protecting your organization from cyber-physical attacks is not easy, but it is essential to keep your clients’ money and personal information secure. With the use of proper prevention methods, you can secure all the data in your physical systems. Also, you can leverage some tools and integrate them into your financial institutions to create strong information security protocols.
