As a user of The Chinese University of Hong Kong, Shenzhen, your information security awareness and active participation are crucial to maintaining the campus's overall information security.
Below are some highly recommended security practices for you:

Keep Your System Up to Date

Ensure that automatic updates are enabled in Windows Update. Similarly, enable automatic updates for non-Microsoft software, especially for browsers, Adobe Acrobat Reader, and other applications you use regularly.

Enable the Windows Firewall

For Windows users, please ensure that the Windows Firewall is turned on in the System and Security Center.

Use Antivirus Software and Keep it Current

Antivirus software is essential for every computer. Without it, you risk losing personal information and files. If you are using Windows 10 or Windows 8, Windows Security or Windows Defender Security Center is already installed on your device. If you are using Windows 7, you can download Microsoft Security Essentials for free.

Lock Your Computer Screen

Always lock your computer when you are away from your desk to prevent unauthorized access to your information and the University's data.

Beware of Phishing Emails

Occasionally, you may receive emails pretending to be from "CUHK-SHENZHEN" or "ITSO," requesting your username and password or prompting you to click on a link. These are often phishing emails containing malicious links. ITSO will never request such information via email, phone, or in person, and no staff member will ever ask for your passwords. If you receive an email requesting account credentials or personal information, do not disclose any details. Instead, report the email to ITSO immediately. If you have already responded to a phishing email, reset your password immediately and notify ITSO.

Take Care of Your Account and Password

You are responsible for safeguarding your CUHK-Shenzhen account and password. Never share your password with others under any circumstances.

Beware of Spam Emails

Spam emails are unsolicited, unwanted, or illegal messages. They consume storage space and may contain malware. While measures are in place to block spam emails, you can take additional steps to reduce the number of spam emails you receive. If you suspect an email is spam (e.g., multiple emails with identical content), forward it to isupport@cuhk.edu.cn. Never reply to spam emails, even if prompted to do so.

Only Install Necessary Applications and Devices

To reduce the risk of cyberattacks, install only the applications you need and remove those you no longer use. Avoid installing any illegal or unauthorized software on your computer.
