The use of technologies like IPSec can help guarantee the following: authenticity, integrity, confidentiality and

Non-repudiation ensures that a communicating party cannot deny having sent or received data, and IPSec achieves this through digital signatures facilitated by IKE with certificate-based authentication and the Authentication Header (AH) protocol. This is a recognized fourth security guarantee alongside authenticity, integrity, and confidentiality in cryptographic protocol design. Together, these four properties represent the core security services that IPSec is designed to provide.

Operability is not a defined security property and is not a guarantee produced by any cryptographic protocol, including IPSec.

'Security' is too broad and non-specific to serve as a discrete technical guarantee alongside authenticity, integrity, and confidentiality.

Usability is a user experience consideration, not a cryptographic security property that IPSec or any network security protocol is designed to provide.
