Which is better VPN or RDP?

Security. Although both VPN and RDP are encrypted through internet connection, a VPN connection is less accessible to threats than a remote desktop connection. For this reason, VPN is often considered more secure than RDP.

How can I access a private network remotely?

The best solution that will allow organizations to access files remotely is to set-up a virtual private network (VPN). A VPN provides a cable-like connection via the Internet between a remote PC and your office's server.

Why is a VPN setup necessary for remote home workers?

Remote Access: A remote access VPN means your employees can log on to your company network from anywhere that has access to the Internet. Whether they are in the coffee shop, traveling, or (hopefully) social isolating at home, a VPN allows your employees to access all the resources they need to get the job done.

What is Cisco Easy VPN?

The Cisco Easy VPN client feature eliminates much of the tedious configuration work by implementing the Cisco Unity Client protocol. This protocol allows most VPN parameters, such as internal IP addresses, internal subnet masks, DHCP server addresses, WINS server addresses, and split-tunneling flags, to be defined at a VPN server, such as a Cisco VPN 3000 series concentrator that is acting as an IPSec server.

What are the two types of VPNs?

Two types of VPNs are supported—site-to-site and remote access. Site-to-site VPNs are used to connect branch offices to corporate offices, for example. Remote access VPNs are used by remote clients to log in to a corporate network. The example in this chapter illustrates the configuration of a remote access VPN that uses ...

What is a Cisco 870 router?

Can you negotiate with a peer in a security association?

Note With manually established security associations, there is no negotiation with the peer , and both sides must specify the same transform set.

Does Cisco Easy VPN support multiple destinations?

Note The Cisco Easy VPN client feature supports configuration of only one destination peer. If your application requires creation of multiple VPN tunnels, you must manually configure the IPSec VPN and Network Address Translation/Peer Address Translation (NAT/PAT) parameters on both the client and the server.

How to enable log levels in Cisco VPN?

Select Log > Log Settings to enable the log levels in the Cisco VPN Client.

Does Cisco VPN require IKE?

Configurations on both sides of the tunnel must match exactly. However, the Cisco VPN Client automatically selects the proper configuration for itself. Therefore, no IKE configuration is necessary on the client PC.

What is the simplest way to connect to the Internet?

The simplest connectivity to the Internet is to use a single device to provide the connectivity and firewall function to the Internet. With everything being in a single device, it is easy to address translation and termination of the VPN tunnels. Complexity arises when you need to add extra Cisco 7200 series routers to the network. This normally leads people into building a network where the corporate network touches the Internet through a network called the DMZ, or demilitarized zone.

Where is NAT configured?

NAT is configured on the router at the border of a stub domain (referred to as the inside network) and a public network such as the Internet (referred to as the outside network ). NAT translates the internal local addresses to globally unique IP addresses before sending packets to the outside network.

How does IPSec work?

In IPSec tunnel mode, the entire original IP datagram is encrypted, and it becomes the payload in a new IP packet. This mode allows a network device, such as a router, to act as an IPSec proxy. That is, the router performs encryption on behalf of the hosts. The source router encrypts packets and forwards them along the IPSec tunnel. The destination router decrypts the original IP datagram and forwards it on to the destination system. Tunnel mode protects against traffic analysis; with tunnel mode, an attacker can only determine the tunnel endpoints and not the true source and destination of the packets passing through the tunnel, even if they are the same as the tunnel endpoints.

What is IPSEC security?

IPSec is a framework of open standards, developed by the Internet Engineering Task Force (IETF), that provides data confidentiality, data integrity, and data authentication between participating peers. IPSec provides these security services at the IP layer; it uses IKE to handle negotiation of protocols and algorithms based on local policy, and to generate the encryption and authentication keys to be used by IPSec. IPSec can be used to protect one or more data flows between a pair of hosts, between a pair of security Cisco 7200 series routers, or between a security Cisco 7200 series router and a host.

What is Cisco IOS firewall?

What is the advantage of Easy VPN?

The main advantage of Easy VPN is that IPSec policies are centrally managed on the server (Head end router providing IPSec feature) and are pushed to client devices. This policy push is known as Mode Configuration. This requires minimum configuration on the end-user side. The IPSec policies can be configured on a RADIUS server and then downloaded to an Easy VPN server, further reducing configuration required on the Easy VPN server.

How many group policies do you need to configure a Radius server?

This could result in lowering operational costs in the long run.

Can two groups of remote users connect to the corporate network?

Now we are required to allow two sets or groups of remote users to connect to the corporate network. Each set must be assigned a different IP address. Most important, the remote users of one group should not be allowed to connect using the profile of the other group, because each group has a unique set of policies for accessing the corporate network.
