Cyber security

The National CERT has been accredited on the international Trusted Introducer CERT team list intended for support to the alert centres in case of compromised information systems security. Thanks to this membership, RATEL, i.e. National CERT, has been able to monitor, collect and exchange timely and reliable data on cyber security incidents and risks. RATEL's active participation in the international meetings and workshops contributes to improve the overall protection against security risks in ICT systems.
