How to programmatically set the properties "liveliness_protection_kind" & "discovery_protection_kind" for DDS participants [13813]

[JaganKumar-TRM]

Without using the governance file, How to programmatically set the properties "liveliness_protection_kind" & "discovery_protection_kind" for DDS participants?.

Because there is no documentation for that on the “https://fast-dds.docs.eprosima.com” site.

Hi @JaganKumar-TRM ,

Unfortunately, what you intend to achieve is not possible. This is because these properties are configured using the Domain Governance Document, which is a CA signed document. Configuring them programmatically would allow for configuring without proper clearance from the CA.

Given this, why is it nevertheless possible to set the message encryption programatically, via "rtps_protection_kind"?

What security issues are created if we are unable to set either of these properties?

Hi @davebranton ,

All the security related properties are indeed being removed in Fast DDS v2.6.0 due mid-March 2022. All of them are already configurable using the signed Domain Governance Document, so applications are already capable of configuring them according to the OMG DDS Security standard.
