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

Non-repudiation ensures that a sender cannot deny having transmitted a message, achieved through digital signatures and certificate-based authentication mechanisms built into IPSec's IKE negotiation. This property binds a verified identity to the transmitted data, preventing later denial. It completes the classic four security properties: authenticity, integrity, confidentiality, and non-repudiation.

Operability is not a recognized cryptographic security property and has no defined meaning in the context of IPSec or network security protocols.

Security is too broad and generic to serve as a distinct fourth property - it encompasses all of the listed attributes rather than naming a specific guarantee.

Usability refers to ease of use in user experience design and is not a security property provided by cryptographic protocols like IPSec.
