introduction to ccna 200-301.Figure 14-1 shows how a typical site-to-site VPN session is established.Branch Office Corporate Headquarters Figure 14-1 Example of a Site-to-Site VPNThere is another VPN technology that protects traffic sent from a specific host to a site; this VPN is called a remote access VPN. as with site-to-site VPNs, traffic between the host and the remote site is encrypted for transmission to prevent eavesdropping. There are two types of remote access VPNs: client-based and clientless. Client-based remote access VPNs rely on hardware or software clients to establish, maintain, and terminate VPN connections. Remote access VPNs are typically chosen for employees or other users who need continuous access to a remote site network with some level of security. a VPN security policy can be enforced to ensure the correct level of access. Cisco AnyConnect is an example of a remote access VPN technology, but there are many other open source and commercial remote access VPN technologies available. Figure 14-2 shows how a typical remote access VPN session is established.Corporate NetworkFigure 14-2 Remote Access VPN Example14.2 Encryption and Tunneling 493Cisco AnyConnect has a variety of security features to ensure that end users have the right level of access to the right devices. As an example of a remote access VPN: Suppose user Joey wants to access the Cisco network, so he initiates the creation of a remote access VPNO Joey's computer is then subjected to specific checks, including whether antivirus software and system patches have been updated to the latest and whether certain applications are installed. In addition, Joey's computer can be forced to perform multiple authentication (e.g., a combination of a password and a valid certificate) before being granted access to the network. It is possible to give Joey's computer access only to mail servers and certain Web servers deployed in a particular VLAN. Figure 14-3 shows an example of a VPN connection established with the Cisco AnyConnect client, which Joey's laptop computer uses to establish a VPN connection to a remote site called RTP.Clientless VPNs (aka secure portals) do not require any software to be installed on the end device. Typically, users simply access a portal to establish a VPN connection, which places the service in a secure container and wipes the session history from the device once the session is terminated. When an authorized user accesses the portal with a Web browser, a VPN connection is established, and when the user exits the portal or closes the Web browser, the VPN connection is terminated. Network administrators can open and monitor the specifics of what can be accessed inside the container, for example, providing links to Web sites or providing an endpoint to manage network devices. Clientless VPNs are a common solution for temporary access needs, such as temporary access to a company's internal network from an unsecured device (a public computer in a hotel or airport). Figure 14-4 shows an example of setting up a Cisco clientless VPN portal.Take the example of user Joey using a friend's computer to check his mail through a clientless VPN. Because Joey's company security policy does not treat that computer as a trusted system, it is not allowed to connect directly to the internal network. Joey has the option of accessing internal network resources through a clientless portal. Before being granted access to a specific resource, Joey's computer needs to be authenticated and specially scanned. If the non-trusted computer Joey is temporarily using passes the security policy checks, he can access a secure portal with a link to his 0utlook mailbox. As soon as Joey clicks Close Browser, a window pops up to inform Joey that the browsing history will be deleted and the secure session will be closed.494 Chapter 14 Security Evasion Techniques
