Windows® 7 IPsec
What is IPsec and what are the different protocols used by it in the Windows 7 Operating System?
The main purpose of IPsec is to authenticate and encrypt the data bits traveling on the packets of IP protocol. IPsec provides interoperable and high quality security services for authenticity, confidentiality, and integrity. It allows you to perform secure data transfer. IPsec is the short term used for IP Security. It comes with data security techniques. IPsec consists of the collective identification process between the communicating parties. When the identities are confirmed, a communication session is initiated and the transfer of coded (or encrypted) data begins. Then, the two parties share a data unlocking key, which decodes the transmitted data bits. IPsec, with encryption technology, is used for securing the virtual private network.
Following are description of IPsec, different protocols used by IPsec, and role of VPN client in Windows 7:
- About IPsec
- Different protocols used by IPsec
- Role of VPN client
IPsec is the Internet protocol security that is necessary for your computer. It keeps your network more secure. It is a security protocol that helps to secure framework and data exchange process. This security service consists of rules and regulations to make communication more secure and reliable. IPsec is a service meant for making the communication between computers more secure and it keeps the data private.
Different protocols used by IPsec
IPsec uses three sub protocols, which are security association (SA), authentication header (AH), and encapsulating security payload (ESP). These protocols initialize the communication by coding and decoding and keep the interchanged data unchanged. Thus, the protocols used in IPsec help to provide secrecy and authenticity to data transfer. Full IETF is also one of the protocols used in IPSec.
Virtual Private Network is commonly known as VPN. VPN helps to create an encrypted connection between the computers and makes the data secure. To configure the VPN client into the Windows 7 Operating System, click 'Start' and then go to 'Control panel'. Then select the ‘Network and Sharing Center’ and click ‘Set up a new connection or network.’ Then a window would open; select the ‘Use my Internet connection’ option and enter the domain name of the VPN server and the name you want to call the connection in the next window.
