https encryption for JCTIC Website and Intranets

posted May 28, 2016, 8:44 PM by WAI LEUNG CHAN   [ updated May 29, 2016, 6:02 PM ]

Recently we upgraded the security settings on our school website and our intranets. With immediate effect, all web traffic to and from your browser to these portals will be encrypted and decrypted automatically through HTTPS (More Info) protection.

To put it in simple terms, it means no one can read any content between your browser and our servers except you. Everything is encrypted.

We will constantly raise the security level of our network services but please do pay more attention to malicious emails, ransom-wares, virus, etc. on the client side. More help could be found on HKSAR Info Security Website.

For any problem, please contact us through email or webform.
