Extranet对于企业业务非常理想:向客户开放企业内部网,利用更直接的联系手段增加企业的竞争力,提高生产效率。但是并非每个客户都值得信赖,网络主管必须要保护自己的网络,防止入侵者。 有很多的黑客使用调制解调器自动拨号软件不断搜索公用电话网中可能有的远程接入点,在找到接入点以后,尝试对口令进行攻击,这给具有远程接入功能的企业造成很大威胁。 当网络管理员对安全有更多的认识,就会感到现有安全控制手段的不足。

Extranet is ideal for business: opening up intranets to customers and using more direct contacts to increase the competitiveness of your business and increase productivity. But not every customer is trustworthy, network supervisors must protect their networks and prevent intruders. Many hackers use modem autodialer software to continuously search for possible remote access points in the public switched telephone network. After finding an access point, attempts to attack the password pose a great threat to enterprises with remote access capabilities. When network administrators have more awareness of security, they feel the inadequacy of existing security controls.
