Ans. GST Systems project has incorporated state of art security framework for data and service security. Besides high end firewalls, intrusion detection, data encryption at rest as well as in motion, complete audit trail, tamper proofing using consistent hashing algorithms, OS and host hardening etc., GSTN is also establishing a primary and secondary Security Operations Command & Control center, which will proactively monitor and protect malicious attack in real time. GSTN is also ensuring secure coding practices through continuous scanning of source code & libraries being used in GST system to protect against commonly known and unknown threats.
