VPN Connectivity

What is A Cisco VPN or Cisco Virtual Private Network ?

Remote-access VPN's allow secure access using a Cisco vpn client to connect to corporate resources by establishing an encrypted tunnel across the Internet.VPN provides the highest level of security through the use of encryption technology that protects the information traversing the VPN from unauthorized access.

In today’s fast-paced business world secure remote connectivity to the office is essential. VPN enable fast, reliable, and secure connectivity to the corporate network from anywhere, anytime, with any device.

VPN technology takes advantage of already existing Internet infrastructure to add new sites or users, thus increasing the reach of the networks with very little changes to the existing infrastructure.

VPNs have become the logical solution for remote-access connectivity for the following reasons:


● Provides secure communications with access rights tailored to individual users, such as employees, contractors, or partners
● Enhances productivity by extending corporate network and applications
● Reduces communications costs and increases flexibility

Remote-Access VPN Security Considerations


Worms, viruses, spyware, hacking, data theft, and application abuse are considered among the greatest security challenges in today’s networks. Remote-access and remote-office VPN connectivity are common points of entry for such threats, due to how VPNs are designed and deployed. For both new and existing IPsec and SSL VPN installations, VPNs are often deployed without proper endpoint and network security. Unprotected or incomplete VPN security can lead to the following network threats:


● Allows remote-user VPN sessions to bring malware into the main office network, causing virus outbreaks that infect other users and network servers
● Allows users to generate unwanted application traffic, such as peer-to-peer file sharing, into the main office network causing slow network traffic conditions and unnecessary consumption of expensive WAN bandwidth

● Enables theft of sensitive information, such as downloaded customer data, from a VPN user desktop
● Enables hackers to hijack remote-access VPN sessions, providing the hacker access to the network as if they were a legitimate user

To combat these threats, the user desktop and the VPN gateway that the user connects to must be properly secured as part of the VPN deployment. User desktops should have endpoint security measures such as data security for data and files generated or downloaded during the VPN session, anti-spyware, antivirus, and personal firewall. The VPN gateway should offer integrated firewall, antivirus, anti-spyware, and intrusion prevention. Alternatively, if the VPN gateway does
not provide these security functions, separate security equipment can be deployed adjacent to the VPN gateway to provide appropriate protection.
Cisco remote-access VPN solutions offer threat-protected VPN services with full firewall, antivirus, anti-spyware, intrusion prevention, application control, and full endpoint security capabilities. These security services are integrated into the VPN platform, delivering a threat-protected VPN solution without any additional equipment, design, deployment, or operational complexity.
