Don't Check Your Personal Email While on District Systems
By checking your personal email on your office computer, you are extending the risk profile of your workplace to include your own personal activities. Attacks that target you as an individual, are now naturally extended to the entire enterprise. Your office email account is carefully managed and secured by policies and the vigilance of your IT team to minimize the risk from suspicious emails, links, and attachments. Once you open your own email account on your office computer, you bypass many of these defenses and render them less effective. If you open that suspicious attachment in your personal email on your office computer, you can infect your system (and eventually many other systems) with malicious software like ransomware that may prevent you or your colleagues from performing their duties.
