C-DAC’s COPS Defender is a protocol hardening solution intended to address the vulnerabilities in transmission SCADA protocols like IEC 60870-5-101 and IEC 60870-5-104 in the power systems. The solution offers to authenticate any control from the control center towards RTUs and prevent any malicious events that may take place due to man-in-the-middle attacks. This also provides an encrypted channel between a control center and the RTUs connected to it. This is aimed to address security concerns like data spoofing, data modification, replay attacks and non-repudiation.

1. Protects communication channel between RTU and control center

2. Identifying possible man-in-the-middle attack 

3. Application layer security adhering to IEC 62351 standards

1. Hardening of the following protocols:

       IEC 60870-5-101

       IEC 60870-5-104

2. Deployable with existing SCADA environment

3. Implements encrypted channel between RTU and control center.

4. Adherence to IEC 62351 standard for providing application layer security.

5. Identifying possible man-in-the-middle attacks and preventing consequent attacks like data spoofing, data modification and replay attack.

1. Adopting Bump In the Wire methodology to protect third party Master Terminal Unit and Remote Terminal Unit 

2. Application layer security adhering to IEC 62351 standards

3. Secured mutual authentication

4. Protects communication channel between RTU and MTU

5. Encryption of data over communication channel

6. Secured key exchange

7. Prevents various attacks like Man in the middle, Replay, Data Modification, Non

Repudiation etc.
