Self-Protection

Passes integrity, confidentiality and availability verification tests under Korean national evaluation criteria

The three elements of integrity, confidentiality and availability under Korean national evaluation criteria

Meets Every National Security Requirement

We built the security functions of the management server and agent to comply with every item of the security requirements for countering cyber threats against Korean government agencies and public institutions.

01

Ensuring Confidentiality

  • Login passwords must comply with password creation rules, and user account information is encrypted and stored securely.
  • Critical data generated or exchanged while the management server and agents are running is encrypted, whether it is stored or transmitted.
  • Critical files are kept hidden, and the encryption keys in use comply with security certification standards.

Algorithm
Plaintext
Encryption: plaintext and a key are fed into the algorithm to produce ciphertext. Decryption: ciphertext and the key are fed into the algorithm to restore the plaintext.

02

Ensuring Integrity

  • To keep operation safe, the critical executables and key running processes of the agent and management server undergo periodic integrity verification.
  • Any files found damaged during integrity verification are restored automatically, and the administrator is notified immediately.
  • The integrity verification procedure complies with security certification standards.

Integrity restored

The file hash did not match, so the file was restored.

03

Ensuring Availability

  • Attempts to change permissions in order to gain the right to modify files are blocked.
  • Attempts to delete critical executables are blocked.
  • Attempts to stop critical running processes are blocked immediately.
  • Session hijacking attempts are blocked, and sessions end automatically after a set period of inactivity.

The action can't be completed.
Access is denied.

Can the agent be protected against removal?

Yes. The agent can be set so that it can only be removed with administrator approval. It can also be set so that users can remove it freely under administrator control.

Is the agent process protected against forced termination?

Yes. The agent process is protected against forced termination. Even if it is terminated for some reason, it restarts immediately and keeps protecting the PC.

Does protection continue if the management server fails?

Yes. If the management server goes down, the agents keep running with the last policy they received, so protection stays in place.
