Following my work with the FreeBSD implementation of RFC 6980 I was happy to present my work at last week’s DENOG 9 meeting.
To make it available to anyone who did not meet me there and go into some more detail that would have exceeded the boundaries of the talk, I will cover the topic here.
After the preceding work on Windows Server 2016 and the FreeBSD testing, as a Linux user, lover and administrator, I of course wanted to take a look at how different Linux systems complied with the RFC 6980 standard.
A Cisco Catalyst 3560 switch running the software “C3560c405ex-UNIVERSALK9-M” version 15.2(2)E4 connecting
A Linux based attacker system running Chiron and
A FreeBSD target system, running different OS versions and configurations and
A Linux based laptop running a control script that remotely performed the necessary tasks on the two machines mentioned above
The main question was: Would the impact on the target system and the possible attacks that were observed with the Windows Server 2016 victim be reproducible on other operating systems? Or would those behave totally differently?
