About swIDch PLC-OTAC

swIDch PLC-OTAC offers an optimized and secure authentication solution specifically designed for Programmable Logic Controller (PLC) devices in industrial control systems (ICS) and operational technology (OT) environments. Utilizing the one-way dynamic authentication OTAC technology, the solution ensures high security with minimal resource requirements. Unlike traditional password-based authentication, PLC-OTAC offers a passwordless multi-factor authentication (MFA) approach that significantly increases security while minimizing disruption and computing demands.

The PLC-OTAC solution neutralizes common vulnerabilities associated with password-based systems, such as default passwords, password sharing, and the inherent weaknesses of static credentials. It employs dynamic one-time authentication codes (OTAC) that are unique for each user and constantly changing, defeating packet sniffing attacks and unauthorized access attempts. The OTAC-based authentication process streamlines the login experience by eliminating the need for usernames or passwords, providing a single-step identification and authentication workflow.

PLC-OTAC offers deployment options to accommodate the specific requirements of each end-user environment. It can be integrated directly onto the PLC in standalone mode, deployed on a central server within the OT network, or implemented in a hybrid configuration combining both approaches. The solution's customizable design supports various authentication code lengths and issuance mediums, such as smartphones or display cards, ensuring integration with existing PLC authentication user interfaces.

Key benefits of swIDch PLC-OTAC

1. Enhanced Security
PLC OTAC strengthens security by using dynamic one-time codes instead of static passwords. This approach significantly reduces the risk of credential theft and unauthorized access. Dynamic codes, valid for a single session only, are resistant to phishing, brute-force attacks, and other methods that exploit static passwords.

2. Passwordless Authentication
PLC OTAC simplifies access with passwordless authentication, eliminating the need for static passwords. This reduces the risk of password-related breaches and lessens the burden on users who no longer need to manage complex passwords. By ensuring that only authorized users can access critical systems, PLC OTAC enhances security and operational efficiency.

3. Flexible Deployment Options
PLC OTAC supports various deployment modes to meet different operational needs:
- Standalone Mode: Installed directly on the PLC, this mode operates independently of network connectivity, ideal for environments with limited or unreliable network access.
- Server Mode: Deployed centrally on a server within the OT network, this mode is suited for large-scale deployments. It allows multiple PLCs to redirect authentication requests to the OTAC server, which manages security centrally.
- Hybrid Mode: Combining local and central server deployment, this mode provides local authentication on the PLC while also leveraging a central server for additional security and failover resilience. It ensures robust protection and continuous operations even during network outages.

4. Efficient Resource Usage
PLC OTAC is designed to be resource-efficient, ensuring minimal impact on PLC performance and overall system operations. Its lightweight architecture is suitable for environments with limited processing power, allowing effective security without compromising system efficiency.

5. Seamless Integration
PLC OTAC integrates smoothly into existing OT environments with minimal disruption. Whether used on individual PLCs or across multiple devices, it provides a straightforward implementation, enhancing security without requiring significant changes to current systems.

6. Operational Continuity
The hybrid deployment mode of PLC OTAC ensures authentication remains functional during network outages or server failures. This resilience minimizes downtime and maintains operational integrity, allowing critical processes to continue without interruption.

7. Scalability
PLC OTAC is adaptable to the scale of your organization. Whether you need to secure a single PLC or an extensive network of devices, PLC OTAC offers a flexible and scalable solution that meets diverse security requirements.

8. Improved User Experience
The passwordless authentication provided by PLC OTAC simplifies the login process for users, eliminating the need for password management.

9. Compliance and Risk Management
Implementing PLC OTAC supports compliance with industry standards and regulatory requirements related to cybersecurity. By adopting advanced authentication methods and minimizing reliance on static passwords, PLC OTAC helps meet regulatory expectations and manage security risks effectively.

10. Cost-Effective Security
PLC OTAC offers a cost-effective solution for enhancing PLC security. Its efficient resource usage and integration reduce the need for additional hardware or extensive operational changes, providing security at a practical cost.

In summary, PLC OTAC by swIDch provides numerous benefits, including enhanced security through dynamic codes, passwordless authentication, flexible deployment options, and efficient resource usage. Its integration, operational continuity, scalability, improved user experience, and support for compliance make it a valuable solution for safeguarding critical industrial control systems.
