What is OT Security?

OT Security, or Operational Technology Security, is the practice of protecting industrial control systems (ICS) and other operational technology (OT) assets from cyber threats. OT systems are used to monitor and control physical devices and processes in critical infrastructure sectors such as energy, transportation, water and wastewater, and manufacturing.

OT security is important because OT systems are increasingly being targeted by cybercriminals. These attacks can have devastating consequences, including physical damage to infrastructure, disruption of essential services, and loss of life.

OT security challenges include:

  • OT systems are often legacy systems that are not designed with security in mind.

  • OT systems are typically isolated from IT networks, which can make it difficult to detect and respond to cyberattacks.

  • OT systems are often complex and interconnected, which can make them vulnerable to cascading failures.

OT security measures include:

  • Network segmentation to isolate OT systems from IT networks and other potential sources of attack.

  • Access control to restrict access to OT systems to authorized personnel.

  • Security monitoring and incident response to detect and respond to cyberattacks promptly.

  • Patch management to keep OT systems up to date with the latest security patches.

  • Security awareness training for OT personnel.

OT security is a critical component of cybersecurity for any organization that operates OT systems. By taking steps to protect OT systems, organizations can reduce the risk of cyberattacks and their associated consequences.

These incidents demonstrate the importance of OT security and the need for organizations to take steps to protect their OT systems from cyber threats.
