因近來發現多起校園帳密外洩事件，故請各位老師、同學定期更換校務系統及email的密碼。以下事項，煩請注意：

1.若您有出國，從國外連線使用過校務系統或email，回國後務必更換密碼；若干國外的機場、旅館、景區免費的WIFI設備資安防護機制較低，常被駭客利用或遭不肖員工盜賣。

2.各系統的帳號與密碼不要相同，有些人一組密碼走天下，若遭外洩，個人所有帳密會全被盜用。
   ■常見的帳密外洩模式 → 使用某網站需要註冊，要留下email與註冊密碼，若遭外洩，駭客會持這組email與密碼嘗試登入您的Gmail、facebook、line、instagram、youtube、校務系統、學校email、網路銀行、證卷帳戶等。

3.不使用代理人程式進行選課，代理人程式會將帳密儲存至雲端或它方伺服器中，極容易遭外洩，造成損失。

4.定期(建議每周)備份自己重要的信件及聯絡人。

5.不要下載、安裝、使用不合法規的軟體，有些盜版軟體、外掛軟體會遠端盜取帳密或檔案。

6.曾經於公用電腦或他人電腦登入WEB MAIL或公務系統，帳號密碼遭側錄，請使用自己的電腦或安全的電腦更換密碼。

7.隨時注意身邊的環境，在使用電腦登入系統時，是否遭監視設備或他人手機遠端錄影，若有懷疑，請至安全場所，更換密碼。

【Security】Please change your school administration system password and email password regularly.

Due to recent incidents of multiple campus account and password leaks, all teachers and students are requested to regularly change their passwords for the school administration system and email. Please note the following:

1. If you have traveled abroad and used the school administration system or email from overseas, be sure to change your password after returning to China; the security protection mechanisms of free WIFI devices in some overseas airports, hotels and scenic spots are low, and they are often exploited by hackers or stolen and sold by unscrupulous employees.

2. Do not use the same username and password for all systems. Some people use the same password for everything, but if it is leaked, all your personal usernames and passwords can be stolen.
   ■Common username and password leakage patterns → When using a website that requires registration, you need to leave your email address and password. If this information is leaked, hackers can use this email address and password to try to log in to your Gmail, Facebook, Line, Instagram, YouTube, school administration system, school email, online banking, securities accounts, etc.

3. Do not use proxy programs for course selection. Proxy programs store account passwords in the cloud or on other servers, which are easily leaked and can cause losses.

4. Regularly (weekly recommended) back up your important emails and contacts.

5. Do not download, install, or use illegal software. Some pirated software and plug-ins can remotely steal account passwords or files.

6. If you have ever logged into your web mail or official system on a public computer or someone else's computer and your account password has been recorded, please change your password using your own computer or a secure computer.

7. Always be aware of your surroundings. When logging into the system on your computer, check if you are being monitored by devices or remotely recorded by someone else's mobile phone. If you have any doubts, please change your password in a safe place.
