Extranet是组织的Intranet的一部分。它是基于Internet协议(TCP / IP)的通信网络。它为贸易伙伴,客户和其他业务提供了对公司Intranet的受控访问。因此,这是一个私有网络,可以与公司外部的授权人员安全地共享公司的内部信息和运营,而无需访问公司的整个网络。要求用户具有ID,密码和其他身份验证机制才能访问该网络。
它以虚拟专用网的形式进行设置,因为由于使用Internet将外部人员连接到组织的Intranet,因此容易受到安全威胁。 VPN可以确保您在公共网络(例如Internet)中的安全网络。传输控制协议(TCP)和Internet协议(IP)用于数据传输。
VPN为基于Internet协议安全体系结构(IPSEC)协议的事务提供了安全保障,因为它为TCP / IP协议提供了额外的安全层,用于在Extranet中进行数据传输。在这一层中,IP数据包被封装以形成一个新的IP数据包,如下所示:
此外,为了为Intranet提供更高的安全性,组织还采取了以下两项措施:
Intranet | Extranet |
---|---|
It is a private network, which cannot be accessed externally. | It may not be called a private network, as it can be assessed externally. It provides limited access to authorized outside-users such as vendors, partners, etc. |
It connects the employees of the company. | It connects the company’s employees with partners. |
It is an independent network, not a part or extension of any other network. | It is an additional part of company’s Intranet. |
Communication takes place only within the organization that owns the network. | External users such as suppliers, customers, and partners are allowed to be a part of intranet to get information, updates, about the organization. |
