IPSec overhead in ESP Tunnel mode - Cisco Community Hi, I am facing a very simple problem with IPSec in ESP Tunnel mode. My objective here is to know the precise overhead added to normal payload by IPSec in ESP tunnel mode. As per Cisco docmentation I read some where that it is up to 57 bytes. However in reality it is taking up to 58 bytes, is it IPsec - WikiMili, The Best Wikipedia Reader The IPsec protocols use a security association, where the communicating parties establish shared security attributes such as algorithms and keys. As such IPsec provides a range of options once it has been determined whether AH or ESP is used. Before exchanging data the two hosts agree on which algorithm is used to encrypt the IP packet, for example DES or IDEA, and which hash function is used How IPSec Works > VPNs and VPN Technologies | Cisco Press Defining Interesting Traffic. Determining what type of traffic is deemed interesting is part of … Understanding IOS IPSec and IKE debugs - Cisco Community

IPSec (engl. Internet Protocol Security) je proširenje IPv4 protokola koje obezbeđuje sigurnosne usluge privatnosti, integriteta, autentifikacije i neporecivosti. IP protokol obezbeđuje komunikacioni kanal sa kraja na kraj i nezavistan je od nižih slojeva, pa se i IPSec može koristiti bez obzira na način implementacije fizičkog sloja i sloja veze.
IPSec është i përkrahur nga Linux.Nëse IPSec nuk është kompiluar nëkernel atëherë bërë këtë para se të përdoret.Kjo bëhët duke shkarkuar IPSec dhe ri-kompiluar Krenelin.pasi që bëhet kjo duhet bërë disa ndryshime në skedën\ etc\ syconfig etwork.Vlera e FORWARD_IPV4 duhet ndërruar në ‘’true’’. Most IPsec implementations consist of an IKE daemon that runs in user space and an IPsec stack in the kernel that processes the actual IP packets. User-space daemons have easy access to mass storage containing configuration information, such as the IPsec endpoint addresses, keys and certificates, as required. IPsec(Internet Protocol Security)은 통신 세션의 각 IP패킷을 암호화하고 인증하는 안전한 인터넷 프로토콜(IP) 통신을 위한 인터넷 프로토콜 스위트이다. 이 보안은 통신 세션의 개별 IP 패킷 을 인증 하고 암호화 함으로써 처리된다. IPsec (IP Security), specificerat i RFC 4301, skapar en gräns mellan skyddade och oskyddade delar av datornätverk. Paket som passerar denna gräns behandlas på olika sätt. Paketen, beroende på hur IPsec är konfigurerat, kan passera ohindrade, kastas bort eller bli behandlade med olika tjänster. IPsec (lyhenne sanoista IP Security Architecture) on joukko TCP/IP-perheeseen kuuluvia tietoliikenneprotokollia Internet-yhteyksien turvaamiseen.Nämä protokollat tarjoavat salauksen, osapuolten todennuksen ja tiedon eheyden varmistamisen.
