As a member of CUHK(SZ), your security awareness and participation play an important role in securing the University's IT environment. Here are some highly recommended security practices for you.

Keep Your System Up to Date

Do this by letting the default Windows Update settings install updates automatically. For application software, enable self-update where available.

Ensure Firewall Is Enabled

With Windows, you can check the firewall status via the Security Center or Action Center on the PC.

Install Anti-virus Software

It is very important to protect your computer from viruses with up-to-date anti-virus software. We recommend you to install Microsoft's anti-virus software for your computer with Windows operating system.

Lock up your computer

If you plan to leave your computer for a long time, please lock it up. This helps to ensure that you are the only user of this system through your CUHK(SZ) account.

Beware of Email Phishing

From time to time, you may receive messages that appear to come from "CUHK(SZ)" or "ITSO" and ask for your username and password, or ask you to click on a link. These are often fake messages and the link may be malicious. ITSO will never ask you for such information by email, phone or in person except it is necessary for system administration. No member of staff will ask for your passwords either. If you do receive emails asking for sensitive account or personal information, don't disclose these details. Report the message to ITSO immediately. If you have replied to any phishing email, reset your password immediately and report the matter to ITSO.

Protecting Your User Account

Protecting the privacy of your CUHK(SZ) account is critical for both your personal life and your life at CUHK(SZ). Your account gives you access to authorized information on campus network, so it should be private and protected. Never disclose your passwords to any third party and do not save your passwords on shared computers.

Beware of Email Spam

Email spam means unsolicited, undesired, or illegal email messages. Spam takes up email storage space and may attach with malicious software. Although we have necessary procedures to prevent spam, there are also some actions you can take to reduce spam. If you think an email you received is spam, for example five emails with the same content, please forward the email to Never reply to any spam email, even if you are invited to do so.

Only Install Necessary Applications and Devices

Limit your applications to those you need and remove software no longer in use to reduce the chance of being attacked. And please avoid installing any illegal software on computers.

Remain Alert

Remain alert and be suspicious of all unsolicited or unexpected emails, even if they appear to originate from a trusted source. Never go to your bank's website by clicking on links included in emails. And think twice about the information and photos you share online.
