No security system is perfect. There is a tradeoff between safety and ease of use. Getting hacked is a big deal. Please be mindful.
Our security policy can be summarized as follows:
You can only access our cluster via ssh from a secure machine
What is a secure machine you may ask? As of Monday, April 21, our answer is as follows. This will change in the coming months.
- A secure machine is one that we control and can protect, as follows:
- The two portals are secure.
- Desktops we control in CCBR 650, 940 and BH 501 are treated as secure. Subject to change.
- Laptops in the lab are currently treated as secure. Subject to change.
- No other machine is treated as secure. This includes the Sali cluster, the QB3 shared cluster, and if you connect via a VPN or ssh tunnel.
- You can only access the portals using an ssh key.
- You can only access the clusters from the portals using a password, never an ssh key.
- You can use ssh keys to move around within the cluster, but only if they are secure.
- Ssh keys must be protected at all times and must never be shared with anyone, even family members or labmates.
- Misuse of sshkeys is a very serious matter. Please guard your ssh key access as you would your bank account.
If you have any doubts about appropriate use of ssh keys, please ask a sysadmin.
