The remote user requires the Cisco VPN client software on his/her computer, once the connection is established the user will receive a private IP address from the ASA and has access to the network.
What is difference between site to site VPN and IPSec VPN?
Site-to-Site VPN provides a site-to-site IPSec connection between your on-premises network and your virtual cloud network (VCN). The IPSec protocol suite encrypts IP traffic before the packets are transferred from the source to the destination and decrypts the traffic when it arrives.
Can IPSec be used as a site to site VPN?
A site-to-site VPN is a permanent connection designed to function as an encrypted link between offices (i.e., “sites”). This is typically set up as an IPsec network connection between networking equipment.

Site to Site VPN: A Site-to-Site VPN is also called as Router-to-Router VPN and is commonly used in the large companies.
What is S2S and P2S?
Unlike S2S connections, P2S connections do not require an on-premises public-facing IP address or a VPN device. P2S connections can be used with S2S connections through the same VPN gateway, as long as all the configuration requirements for both connections are compatible.
What are the 3 protocols used in IPsec?
IPsec is a suite of protocols widely used to secure connections over the internet. The three main protocols comprising IPsec are: Authentication Header (AH), Encapsulating Security Payload (ESP), and Internet Key Exchange (IKE).
What is the difference between IPsec and GRE tunnel?
IPsec provides more comprehensive security for IP tunneling, while GRE tunnels work well when network teams need to tunnel with multiple protocols or multicast. Generic Routing Encapsulation, or GRE, and IPsec both encase packets, but the two protocols have different requirements...
What is a benefit of site-to-site IPsec VPNs?
Site-to-site VPN security is the most important benefit, as IPsec protocols will ensure all traffic is encrypted in transit through the VPN tunnel. The site-to-site VPN tunnel only allows traffic from one end to the other, blocking any attempts to intercept the traffic from the outside.
How does remote access VPN Work?
A remote access VPN works by creating a virtual tunnel between an employee's device and the company's network. This tunnel goes through the public internet but the data sent back and forth through it is protected by encryption and security protocols to help keep it private and secure.
How does Cisco VPN client work?
The VPN takes your computer's request and sends it to a website or system. The requested data is then forwarded back to you through that same secure connection. At CMU, we use the Cisco AnyConnect Secure Mobility Client to connect to the network through VPN.
What is VPN and why do I need it?
VPN stands for virtual private network. In basic terms, a VPN provides an encrypted server and hides your IP address from corporations, government agencies and would-be hackers. A VPN protects your identity even if you are using public or shared Wi-Fi, and your data will be kept private from any prying internet eyes.
Is Cisco AnyConnect VPN free?
Cisco AnyConnect is a free, easy to use, and worthwhile VPN client for Microsoft Windows computers. It's secure and doesn't require a lot of maintenance.
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?
Cisco IOS software provides an extensive set of security features with which you can configure a simple or elaborate firewall, according to your particular requirements. When you configure Cisco IOS firewall features on your Cisco router, you turn your router into an effective, robust firewall.
How does extranet work?
In the extranet scenario, the headquarters and business partner are connected through a secure IPSec tunnel and the business partner is given access only to the headquarters public server to perform various IP-based network tasks, such as placing and managing product orders.
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.
Does Cisco 7200 support intrusion detection?

How to check availability of VPN?
Check the availability of the VPN tunnel by pinging a device from the remote subnet. For example, send a ping request from a workstation at the main office to a server located at the branch office:
What is the encryption key for VPN?
Encryption key is another thing that should be identical on both routers that participate in the VPN tunnel formation. I recommend making it no less than 50 characters so that it contains digits, letters and special characters. For this example, we’ll just use a simple “ 12345 ” key, but that’s not a good idea for a real VPN tunnel.#N#For the main office:#N#R-MAIN (config)##N#crypto isakmp key 0 12345 address 2.2.2.2#N#For the branch office:#N#R-BRANCH (config)##N#crypto isakmp key 0 12345 address 1.1.1.2#N#The configuration example has the values that you should change to your own highlighted in red. The “ 0 ” in the “ crypto isakmp key ” line means that the key is being entered in an unencrypted form. You should not change this to any other value. When you look at the running configuration, in certain cases the crypto key gets encrypted and displayed in a scrambled format. This is indicated by the number “ 7 ” after the “crypto isakmp key”:#N#R-MAIN#sh run#N#/...output cut.../#N#crypto isakmp key 7 ^bn UjbsdfgsujGsdf address 1.1.1.2#N#/...output cut.../#N#This does not mean that the key itself has changed, it means that it is displayed (!) in an encrypted format.#N#Note that on each router we are specifying the external IP address of the remote location (i.e. we are saying use this key to communicate with this remote mate’s address)

How to use SASE?
Some of the benefits of using a SASE are that it allows companies to: 1 Provide branch offices and retail stores with access to the cloud or the data center. 2 Quickly identify users, devices and applications. 3 Consistently apply security policies across multiple locations and enforce least-privileged access. 4 Dramatically simplify their IT infrastructure and reduce costs since they can use a single cloud-based solution instead of buying and managing multiple point products.
