Rapid growth of the Internet makes everyone in the world can communicate with each other easily and quickly. At first the security is not the purpose of the design TCP / IP. Only after the year 1995 where the Internet becomes public consumption and trade traffic through the Internet people began to realize the importance of the Internet network security. For Internet users who require privacy in communicating course there are the problems that arise in everyday situations, such as a company that will send important documents to branch offices via inter net requires a situation where the safe path through the observation of the other party, modification package data by other parties or spoofing.
One solution of the problems above is to use IPSEC.
IPSEC is a standard created by the Internet Engineering Task Force (IETF) that allows for secure data transmission in data communication lines that are not protected like the Internet safely.
IPSEC works at the network layer, protecting and mengotentifikasi IP packet communication between the host and works well on IPv6 and IPv4 traffic.
IPSEC is actually a feature that is owned by IPv6 but by some developers applied to the IPv4.
IPSEC has 4 fruit elements, namely:
1. AH (authentication header)
2. ESP (encasulapting security payload)
3. IPcomp (IP payload compression)
4. IKE (Internet key exchange)
In general, IPSEC services provided are:
1. Confidentiality of data, the data sender can encrypt data packet prior to transmit data.
2. Data Integrity, the recipient can authenticate packet sent by the sender to ensure that data is not plowed during transmission.
3. Data Origin Authentication, the recipient can autehenticate origin of IPSEC packet is sent.
4. Anti-Replay, the receiver can detect and reject packets that have been hijacked.
The end result of the final project courses EL-695 Information Systems Security This is a review mechanism of the workings of the IPSEC and the use of the Internet in this case the author will use a VPN (Virtual Private Network) as a case study.
