计算机网络的安全威胁及其防御机制研究

计算机网络正面临着严重的安全威胁,这些威胁主要有端口扫描、网页软件漏洞、拒绝服务攻击、IP欺骗等,而现行的防火墙技术、入侵检测系统、加密技术、虚拟专用网技术等在防范计算机安全威胁方面都有其自身的弱点,因此,必须进一步改进和加强计算机网络安全技术,完善计算机网络安全的有效管理。

The Security Threats and the Defense Mechanism Resarch about Computer Network

Computer networks are facing with a serious security threat. These threats are mainly about port scanning, web software vulnera-bilities, denial of service attacks, IP fraud and so on, and the current Firewall technology, Intrusion Detection System, Encryption, Virtual private network technology in prevention of threats to computer security have their own weaknesses. Therefore, we must further improve and strengthen the security of computer network technology, and we should perfect the effective security ma...
