基于邮件服务空间预留的电子邮件炸弹攻击防御研究

摘要

E-mail bomber attack will result in overlfow of E-mail server space so that the E-mail recipients can’t receive new E-mails. Not only does it disturb user’s work that normally uses the e-mail system, but it also inlfuences security of mail servers. Because of the limitation of E-mail bomber ifltering technology, an effective strategy of E-mail bomber attack prevention based on user priority’s reservation of E-mail service space is put forward in this paper. The strategy can effectively avoid overlfow of E-mail server space and insure that the higher priority users normally use the E-mail system.%电子邮件炸弹攻击导致电子邮件服务空间溢出而无法接收新的电子邮件，不仅会干扰用户电子邮件系统的正常使用，甚至影响到邮件系统所在服务器的安全。由于电子邮件炸弹过滤技术的局限性，文章提出了基于用户优先权的邮件服务空间预留策略，该策略能够有效避免由于遭受电子邮件炸弹攻击导致的电子邮件服务空间溢出，确保高优先权的用户能够正常使用电子邮件系统。
