With the increase in vulnerabilities in operational technology infrastructure, it's important to deploy unidirectional hardware gateways to restrict entry into OT networks, says Ajit Jha, Head-cybersecurity, L&T Technology Services.
"The first thing that you have to do is work on redundancy so that you can actually run a pen test on one set of hardware while not touching the other set of hardware so the production does not change," Jha says.
In this interview (see audio link below photo) at Information Security Media Group's recent Fraud and Breach Prevention Summit in Bengaluru, Jha discusses:
- A security framework to protect OT from attacks
- Integrating IT security with OT infrastructure
- The importance of building redundancy to avoid disruption
