IPsec

(networking, protocol, security)
("IP Secure"?) A protocol that provides security for transmission of sensitive information over unprotected networks such as the Internet. IPsec acts at the network layer, protecting and authenticating IP packets between participating devices ("peers"), such as Cisco routers.

IETF IPsec.

IPsec

(IP SECurity) A security protocol from the IETF that provides authentication and encryption over the Internet. Unlike SSL, which provides services at layer 4 and secures two applications, IPsec works at layer 3 and secures everything in the network. Also unlike SSL, which is typically built into the Web browser, IPsec requires a client installation. IPsec can access both Web and non-Web applications, whereas SSL requires workarounds for non-Web access such as file sharing and backup.

IPsec is supported by IPv6. Since IPsec was designed for the IP protocol, it has wide industry support for virtual private networks (VPNs) on the Internet. See VPN, IKE, IPv6 and security protocol.

This paper combines AH with ESP when implementing IPSec compression in the 6LoWPAN network.
In contrast to IPSec VPNs, which connect remote devices to trusted networks, SSL VPNs connect remote users to specific applications and network resources inside of trusted networks via a Web portal configured to proxy the traffic.
IPsec VPN protects the data travelling from source to the destination with help of different protocols namely Internet Key Exchange (IKE), Encapsulating Security Payload (ESP) and Authentication Header (AH).
Once the above steps have been concluded, the IPSec tunnels are destroyed.

La transferencia de datos del segundo escenario, involucran las cabeceras del primer escenario, pero en la tercera capa del modelo OSI se aplica el protocolo IPSEC, el cual agrega un peso de 20 bytes de cabecera como minimo, segun Ranjbar (2007).
Internet Protocol Security or "IPSec" is used to secure the confidentiality, integrity, and authentication of the data sent between two machines.
IPSec is a method of authenticating and encrypting data transferred between pairs of hosts.
To reduce weaknesses of applications is possible to use IPSec. It is helping to secure network communications through policies between clients and their mail servers or between mail servers.
Besides VoIP and IPsec programs, online banking sites also require small packets of data to be encrypted, because of all the fields and graphical elements that tend to appear on the page.
According to the company, when running Fireware XTM, WatchGuard Firebox X Core 550e series performs packet filtering 33% faster and gains a 470% increase in IPSEC VPN performance.
The unit supports embedded IPSec VPN protocols, allowing users to establish up to 16 simultaneous encrypted private tunnels over the Internet.
