Az Internet Protocol Security (IPsec) egy protokoll csomag az Internet Protokoll (IP) alapú kommunikáció biztonságosabbá tételére a kommunikációs viszony minden egyes csomagja hitelesítésével és titkosításával.

Biztonsági architektúra

Az IPsec csomag egy nyílt szabvány. Az IPsec az alábbi protokollokat használja:

• Authentication Headers (AH)
• Encapsulating Security Payloads (ESP)
• Security Associations (SA)

Szoftver megvalósítás

• NRL IPsec, one of the original sources of IPsec code.
• OpenBSD
• "IPsec" a Juniper Operating Systems-ben
• "IPsec" a Cisco IOS Software-ben
• "IPsec" a Microsoft Windows-ban, nevezetesen a következőkben: Windows XP, Windows 2000, Windows 2003, Windows Vista, Windows Server 2008, és Windows 7

Szabványosítás állása

Az IPsec-et az IPv6-tal párhuzamosan fejlesztették ki. Az IPsec-nek rendelkezésre kell állnia az IPv6 minden szabványos megvalósításában.
