关于软件的安全更新研究

Research on the Security of Software Updates

在网络快速发展与应用的时代,计算机系统正遭受着众多病毒的侵害,无形中给计算机用户带来了极大的损失。因此,为了有效地避免病毒的侵袭,除了提高系统安全防范意识,最有效的办法就是进行软件更新,及时给系统打补丁。首先介绍了基于补丁的漏洞攻击,以此说明,由于目前补丁发布方式的缓慢,造成大量蠕虫对系统的攻击,然后提出了利用End-hostbasedmulticast模式进行补丁的发布,达到迅速发布补丁的效果,改善目前补丁发布迟缓的现况。新补丁发布方式是基于理想状况下提出的,具体实践需要进一步的研究与证实。

With the rapid development of the network, computer systems are suffered by more viruses and bring the user heavy losses.. Therefore, Software update is the effective way to avoid the viruse. In this paper, we first introduced the patch-based exploits, then proposed the new model （End-host based multicast） to release patch rapidly. The new model is proposed based on ideal conditions, still need further research.
