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

Non-repudiation ensures that a sender cannot deny having sent a message, which IPSec supports through the use of digital signatures and authentication headers (AH). Together with authenticity (verifying identity), integrity (ensuring data is unaltered), and confidentiality (encrypting data via ESP), these four properties form the core security guarantees of IPSec. This aligns with the broader information assurance model used in security certifications and standards.

'Operability' is a system reliability concept, not a security property provided by IPSec or any cryptographic protocol.

'Security' is too broad and vague to be a specific technical guarantee alongside authenticity, integrity, and confidentiality.

'Usability' is a user experience concept and is not a security property that IPSec or cryptographic protocols are designed to provide.
