# 'Programmable Logic Controller OTAC'

# to revolutionise ICS & OT security

 

 

Programmable logic controllers (PLC) serve as key component of ICS and OT systems and are equally susceptible to cyber-attacks, with inadequate access control and authentication within these systems posing a major challenge. With this in mind, swIDch’s Programmable Logic Controller OTAC provides a highly optimised and highly secure authentication solution specifically for PLC devices. It utilises our dynamic 'one-time authentication code' (OTAC) technology to resolve typical ICS/OT security challenges.  
   
OTAC ensures only known and authorised users/devices can access PLCs using dynamic, non-reusable, constantly changing code guaranteed with 0% duplicates (defeats packet sniffing attacks).

# How to protect IoT with zero trust

Many solutions are being proposed to protect IoT while minimizing changes to the already established IoT environment. Zero trust is a security strategy based on the principle of verifying and monitoring all access, and protecting devices through through this continuous verification and monitoring is rapidly gaining momentum.
