IPsec IKEv1 and IKEv2 Protocol Traffic Dataset with Negotiated Cipher Suites

Eleven captures covering the IPsec failure modes that matter. Five IKEv2 tunnels are graded A as a correct reference posture; six are deliberately misconfigured across MODP-1024, MODP-1536, 3DES, DES, NULL encryption, SHA-1 integrity and IKEv1 Aggressive Mode. Each misconfiguration isolates a different variable, so the cipher finding can be separated from the exchange-mode finding and the group finding from both. The packet table carries the full observable content: endpoints, protocol, ports, ESP SPI and sequence. Known limits are stated in the shipped dataset card rather than left for a reviewer to discover. The original pcap captures are published alongside this table in the project repository.
