A few of my colleagues have been on VMWare ESXi training in the last few years and one of the things they brought back is that we should disable SSH. While the trainers seem to be fairly clear on this as a policy none of my colleagues thought to ask why as it's not something that we have needed to use, until now.
As such, my question is, are there any real security concerns regarding allowing SSH access (over and above the other forms of access) or is it just a matter of if we are not using it then we shouldn't leave an extra surface to to attack.
Thanks,
Sam
