Is your OT network protected? Warning signs and how to act

In a world where industrial operations are increasingly dependent on technology, the security of OT (Operational Technology) networks has become a critical issue. However, many organizations still underestimate the risks involved with an exposed or poorly protected network.

The question is simple: How secure is your OT network today?

What is an OT network and why does its security matter?

OT networks are those that allow monitoring, controlling and automating industrial processes in sectors such as energy, oil and gas, mining, water or transportation. Its function is to connect equipment such as sensors, SCADA, PLCs or DCS systems, to ensure operational continuity.

The challenge is that, unlike traditional IT networks, OTs were not designed with cybersecurity in mind. This makes them an attractive target for attackers seeking to stop operations, steal information, or even damage physical equipment.

Warning signs that your OT network is not protected

If you notice any of these points, it's time to act:

1. Uncontrolled access: there is no clear management of who enters or leaves the network.
   
   
2. Outdated systems: PLCs, SCADA or servers that have been without security patches for years.
   
   
3. Direct Internet connection: one of the main gateways for attacks.
   
   
4. Lack of constant monitoring: there are no real-time alerts about anomalies or intrusion attempts.
   
   
5. Dependency on weak or repeated passwords: a common mistake that facilitates unauthorized access.
   
   
6. Ignorance of the asset inventory: If you don't know what devices are connected, you can't protect them either.
   
   

How to act to protect your OT network

The good news is that strengthening the security of your OT network is possible with clear and strategic actions:

• Map your network: identifies all connected devices and their level of criticism.
  
  
• Segment traffic: separates the OT network from the corporate network to reduce risks.
  
  
• Update and apply patches: even older systems can be reinforced with basic security measures.
  
  
• Implement real-time monitoring: telemetry and cybersecurity solutions that detect abnormal behavior.
  
  
• Empower your staff: many attacks start with human error. Awareness-raising is key.
  
  
• Conduct regular vulnerability assessments: to detect and correct weaknesses before attackers do so.
  
  

The value of anticipating

Ignoring warning signs can be costly. A cyberattack on an OT network doesn't just involve economic losses: it can interrupt production, damage critical assets and affect people's security.

The best strategy is forestall, implement preventive measures and work with experts who understand both industrial operation and cybersecurity.

Conclusion

The question isn't whether your OT network will be attacked, but when. Every organization should ask itself: Am I prepared to resist and recover from an incident?

In an environment where technology is constantly evolving, protecting your OT network isn't optional: it's an investment in continuity, security and resilience of your operation.
