Understanding the Differences Between OT and IT Security

To fully appreciate the importance of the NSE7_OTS-7.2 exam, it is essential to distinguish between OT and IT security. While IT security focuses on protecting data, networks, and digital assets, OT security emphasizes safeguarding physical processes, industrial systems, and critical infrastructure. This distinction highlights why Fortinet’s specialized certification is vital for professionals securing industrial environments.

Focus on Availability vs Confidentiality

In IT environments, confidentiality and integrity of data are often prioritized. In contrast, OT systems prioritize availability and uptime, since even brief outages can result in massive disruptions.

Lifespan of Devices

OT devices are designed to last for decades, while IT systems are refreshed more frequently. This leads to security challenges, as many OT devices lack modern security features and cannot be easily patched.

Protocols and Communication

Unlike IT, which uses standard protocols such as TCP/IP, OT environments rely on specialized industrial protocols like Modbus, DNP3, and PROFINET. These protocols were not originally designed with security in mind.

Impact of Attacks

In IT, breaches often result in stolen data or financial losses. In OT, attacks can cause physical damage, safety hazards, or national security implications.

Understanding these differences is a critical step in preparing for the exam, as they underpin the rationale behind Fortinet’s approach to OT security.
