Is your small business protected against the growing threat of cyber-attacks? With the rise of online crime, investing in an effective cybersecurity strategy is a must for small businesses. But where do you start?
OT cybersecurity safeguards operational technology assets like computers, servers, data centers, and networks. So what is OT cybersecurity, and how can you use it to protect your small business?
This guide answers these issues and provides key cybercrime prevention practices for your organization. You’ll learn about best practices for securing your systems and data and how to create a culture of security within your organization.
What Is OT Cybersecurity?
As a small business, protecting yourself from cyberattacks is a must. But what is OT cybersecurity?
Operational technology (OT) refers to digital systems that check and control physical devices, including building automation, industrial control, and physical security. Small firms must safeguard these systems from hackers and criminal agents.
Luckily, there are a few essential steps you can take to protect your business from OT cybersecurity threats:
- Check for software updates regularly. Software updates protect your systems from new dangers. Check for new software updates periodically and install them when they become available.
- Educate your staff. Make sure your staff is well-informed about the basics of OT cybersecurity and aware of the latest threats. Regular training can help your team stay informed and alert regarding cyber threats.
- Check your networks. Invest in a reliable network monitoring system to quickly detect any unusual activity on your networks and appropriately respond to potential threats.
- Install strong authentication measures. Strong authentication measures can protect access points by requiring users to provide many forms of authentication before they gain access.
Why OT Environments Are Vulnerable to Cyber Threats
As technology continues to evolve, so does the number of potential cyber threats your small business can face. One of the most vulnerable types of technology your company might use is Operational Technology (OT). OT networks often manage physical processes and represent the interface between physical and digital systems within the same environment.
That’s why small businesses need to understand OT cybersecurity and why their OT environments are particularly vulnerable to cyber threats. Reasons include:
- OT systems are often older and have fewer built-in security features compared to newer IT systems.
- Many OT systems have been built around existing physical infrastructure, which can make it challenging to secure the networks properly.
- As these systems are often connected with other external networks, they create an expanded attack surface easily exploitable by malicious actors.
- Security patches may not always be available, and in some cases, there may be no patching system. This opens the network to potential vulnerabilities and creates more opportunities for attackers to exploit weaknesses.
By understanding why OT environments are especially vulnerable to cyber threats, small businesses can be better equipped with the information they need to protect their businesses from potential attacks related to operational technology.
Assessing the Risks: Identifying Critical Operational Technology
The next step to bolstering your OT cybersecurity is assessing the risks. This means looking closely at your operational technology and identifying which parts are critical to your business. To do this, you should:
- Check for vulnerabilities: scan devices to identify any flaws in the system that can be exploited.
- Analyze the consequences: determine what risks may occur if a vulnerability is exploited and what impact it will have on your business operations and data security.
- Review existing policies: look for any gaps or weaknesses in your OT policy that could lead to an attack or a breach.
- Install security measures: ensure that all your systems, networks, and devices are secured with up-to-date software and encryption protocols to protect them from malicious actors.
By following these steps, you’ll be able to understand better the unique risks associated with OT cybersecurity and take the necessary steps to protect your business from potential threats.
Developing an OT Cybersecurity Strategy
When it comes to developing an OT cybersecurity strategy, there are some essential steps that small businesses must take to protect themselves from cyberattacks. These include:
Identify and Assess Risks
The first step is to identify and assess potential risks within the organization’s operational technology. This includes both known and potential threats, such as cyber-attacks, malware, phishing attempts, malicious insiders, and data loss due to hardware or software failures. Once identified, the risks should be evaluated for their severity and mitigated accordingly.
Install Security Procedures
The next step is to install security procedures specifically designed for the organization’s operational technology. These could include authentication protocols, access control policies, system monitoring tools, and data encryption solutions. It is also essential that these procedures are regularly tested to ensure they remain effective at protecting against potential threats.
Deploy Software Updates
It is also essential that all software used within the organization’s operational technology be updated regularly with the latest firmware updates and security patches. These updates ensure that any weaknesses or vulnerabilities in the system have been addressed on time before they become problems.
Check Network Traffic
Finally, it is important to check network traffic regularly to quickly detect any suspicious activity or attempted intrusions into the system. This includes monitoring devices connected to the network and their activities on external networks. Monitoring tools such as intrusion detection systems (IDS) can be used for this purpose.
Implementing Safeguards to Protect OT Systems
Securing industrial OT networks requires specialized expertise, and one of the best ways to protect your business is to develop a comprehensive OT cybersecurity plan. Here are some basic steps to get started:
Deploy Security Solutions
Your security plan should include deploying suitable security solutions to protect your OT systems. These solutions should detect malicious activities, check for changes in the environment, and alert you when suspicious activity is detected. Some of the most popular security solutions that can be used for this purpose include intrusion detection systems, firewall technologies, endpoint protection solutions, and anti-malware software.
Install Network Segmentation
Installing network segmentation is another critical step in creating an effective cybersecurity plan. This process involves dividing the industrial network into smaller parts (segments) to manage each segment independently. By doing this, you can better identify potentially malicious activity, limit access to essential system components, and reduce the risk of unauthorized access or malicious attacks from outside sources.
Regularly Check Network Activity
Finally, ensure you regularly monitor network traffic and activity for signs of suspicious or malicious activity. This will help ensure that any suspicious behavior is detected quickly and can provide valuable insight into who may have been involved in suspicious activities or attempted intrusions on your network.
Continuous Monitoring: Reviewing and Improving OT Cybersecurity
The last and most crucial step for protecting your small business is continuous monitoring. As the cybersecurity landscape continues to evolve, small businesses must remain vigilant about protecting their OT systems. To do this, you need to be reviewing your OT security solutions on an ongoing basis.
You can achieve this through the following:
- Regular updates and patching of cybersecurity software and operating systems. Keeping your systems up-to-date with the latest patches is essential as it helps protect against any vulnerabilities that hackers may have identified and exploited.
- Monitoring network activity, such as user logins, file access attempts, or data transfers from critical servers or databases, can help identify any suspicious activity that might indicate a breach has occurred or is being attempted.
- Training staff on identifying potential phishing emails can help ensure that malicious links sent via email are not clicked by an unwitting staff member and exploited by hackers.
- Implementing two-factor authentication at all access layers can help thwart unauthorized access attempts before they even become a threat to OT systems.
- Establishing a baseline security configuration for all OT systems provides a reference point for what constitutes normal, everyday traffic versus something suspicious that could say a potential breach attempt is underway.
- Performing regular penetration tests of the external network can identify any weaknesses in the external infrastructure that could be exploited by attackers attempting to gain access to internal networks containing OT systems and equipment.
By reviewing your security solutions regularly and making improvements when necessary, you can ensure your small business remains secure from cyber threats targeting your IT infrastructure and its associated resources – now and in the future!
