安全扫描技术在网络安全中的应用

Application of Security Scanning Technology in Network Security

当前,人们已经进入到信息时代,对于计算机网络的普遍运用让人们的日常工作、生活、学习等许多方面都变得更加便利,同时又因为网络自身所具有的开放性、复杂程度高等特点,从而存在许多不安全的风险。而存在部分人群,利用网络来获取有价值的信息,以此进行非法牟利,使得一些公司与个人承受损失,人们通常将这些人称之为黑客。黑客在进行信息获取的首先一步便是对目标主机加以扫描,利用扫描来掌握漏洞,进而为后续达成非法目标而做好准备。同时,网络管理人员也能够借助扫描技术预先发觉网络中存在的问题,通过采取有效的防护措施来防止入侵者对系统进行攻击,也就能够大幅提升网络的安全性。

At present, people have entered the information age. The widespread use of computer networks has made people’s daily work, life, and study more convenient. At the same time, because of the openness and high complexity of the network itself, there are many risks of insecurity. However, there are some people who use the Internet to obtain valuable information for illegal profit, causing some companies and individuals to suffer losses. People usually call these people hackers. The first step for hackers to obtain information is to scan the target host, use the scan to grasp the vulnerabilities, and prepare for subsequent illegal targets. At the same time, network administrators can also use scanning technology to detect problems in the network in advance, and by taking effective protective measures to prevent intruders from attacking the system, the security of the network can be greatly improved.
