Information Security Tips (July 2025) – Handling Confidential Information and Mass Emails

/in /by
  1. Handling Confidential Information
    • Protect Confidential Data: When dealing with confidential information, use strong passwords and encryption tools, especially when data needs to be taken off-campus.
    • Delete Immediately: After processing confidential data, delete any copies immediately to minimize the risk of data leakage.
    • Avoid Public Networks: Never process or transmit confidential data over public Wi-Fi networks or shared computers.
  2. Handling Mass Emails
    • Check Before Sending:
      • Carefully verify recipients, content, and attachments before sending emails, especially to third parties, as emails cannot be retracted once sent.
      • Use “Blind Carbon Copy (Bcc)” to protect recipients’ privacy and prevent unnecessary email replies caused by “Reply All”.
    • Clear Subject Line: Use a clear and specific subject line to help recipients distinguish legitimate emails from spam or phishing attempts.
  3. Other Tips
    • Account Security: Enable two-factor authentication (2FA) for accounts used to handle confidential data, and use strong, unique passwords.
    • Device Protection: Use biometric authentication (e.g., fingerprint or facial recognition) to secure your devices.
    • System Updates: Regularly update your operating system, browser, and software to patch security vulnerabilities. Enable real-time antivirus protection and perform regular scans.
