【Abstract】 Email service, a prevalent internet service, stands as one of the indispensable system services within campus networks. Email communication offers convenience in daily work and academic pursuits. However, it has also emerged as a primary target for cyberattacks. Amid the increasingly grave challenges in cybersecurity, the secure operation and maintenance of email systems and the safety management of communications have become crucial focal points in information security protection for campus networks. This paper conducts an analysis of the current email security situation and puts forward countermeasures against email security risks from multiple perspectives, including the establishment of a comprehensive security technology architecture system, the implementation of secure extension protocols, the reinforcement of information security and account protection, the enhancement of email gateway security, and the improvement of user security awareness. These measures play a crucial role in advancing information security on campus environments.更多还原
