Watch out for PLCs controlling critical infrastructure
Programmable Logic Controllers (PLCs) are computer-based systems that are used to control industrial processes, such as those in manufacturing, power plants, and water treatment facilities. They are designed to be rugged and reliable, and they are often found in environments where they are subject to harsh conditions and frequent use.
The importance of cybersecurity for PLCs
Despite their durability and reliability, PLCs also need cybersecurity protection. This is because PLCs are connected to networks, and they are often used to control critical infrastructure. As a result, they can be targeted by cybercriminals who want to gain access to sensitive data or disrupt critical processes.
One of the main reasons why PLCs need cybersecurity is because they are often connected to the internet. This means that they can be accessed remotely, and this can present a security risk if proper precautions are not taken. Cybercriminals can use a variety of tactics to try to gain access to a PLC, including phishing attacks, malware, and other forms of cyber espionage.
Another reason why PLCs need cybersecurity is because they are often used to control critical infrastructure. This includes things like power plants, water treatment facilities, and manufacturing plants. If a PLC is compromised, it could potentially lead to serious disruptions or even damage to the infrastructure it controls.
Siemens cyber attack
Siemens SIMANTIC devices were hit by a cyber attack last year. A security breach allowed cybercriminals to carry out multiple sophisticated attacks on Siemens SIMATIC devices and the associated TIA Portal. That caused quite a stir. Because it meant that cunning hackers had the opportunity to gain complete control of every PLC per affected Siemens product line.
How do you protect your PLCs from digital danger?
There are a number of measures that can be taken to protect PLCs from cyber threats. These include using secure passwords, implementing firewalls, and regularly updating software. It is also important to train employees on cybersecurity best practices, as they are often the first line of defense against cyber threats.
In summary, PLCs need cybersecurity protection because they are connected to networks, they can be accessed remotely, and they are often used to control critical infrastructure. By taking the necessary precautions and implementing proper cybersecurity measures, PLCs can be kept safe from cyber threats.
