Security & VPN
Today's networks are more extensive in terms of geographic reach and the internal and external communities they interconnect. They are more complex, support a wide variety of applications and services, and handle converged data, voice, and video traffic across wired and wireless connections. They are also increasingly open. They use untrusted public networks, are a business tool that touch customers and suppliers and they connect partners. In fact, division between the public and private network has blurred.
The extensive, complex and open nature of the network environment increases the need for robust and comprehensive security, because any point the network touches must be both protected and protected against.
Traffic must be protected as it travels across unprotected domains and network segments. The two main technologies providing secure connectivity are:
• VPNs. VPNs provide network-layer secure connectivity. The most prevalent protocol for VPNs today is IPSec which provides authentication, encryption, and address concealment. It is used both for site-to-site secure connectivity and remote access to head office connectivity.
• Secure Socket Layer (SSL), a protocol developed by Netscape for transmitting private documents via the Internet. SSL works by using a public key to encrypt data transferred over the SSL connection. Both Netscape Navigator and Internet Explorer support SSL and many websites use the protocol to obtain confidential user information such as credit card numbers. By convention, URLs that require an SSL connection start with https: rather than http. SSL creates a secure connection between a client and a server, over which any amount of data can be sent securely.
