I don't understand what exactly you are referring to. How is the above related to responding to unsolicited IKE requests? Regards, Tobias
Re: [strongSwan] Strongswan responds to scan attack

This could allow remote attackers to compromise the confidentiality and integrity of the data by decrypting and modifying individual ESP and AH packets.

And what exactly makes a request unsolicited? Anyway, there is the charon.initiator_only option to ignore any initial IKE messages. Regards, Tobias
[strongSwan] Strongswan responds to scan attack
Hi Is there a configuration to avoid strongswan from responding to unsolicited request from scans, even when strongswan is not configured with an endpoint configuration, This was detected with PCI auditing tools Thanks, Naveen
