All users are responsible for the security of their computers per Campus and UC Network Policies and Procedures outlined by the following:
(These are outlined also at: UCSB Network Policy and Procedures) |
Requirements
Proper Allowance of Access and Use
As outlined in the University of California Electronic Communications Policy:
- Access is to be restricted to University Users (As defined as University students, staff, faculty and affiliated with the University)
- Public (Non-University Users) may only have access to machines that have been authorized as Public Use/Access per sponsorship by the University.
This means that any and all access to machines hosted on the campus network should not have 'open access'.
Strong Passwords and/or SSH Keys on accounts or services running on the machine
...
The definition of a 'Strong' password is:
- Be at least 10 12 characters long (However, more is better)
- Case sensitive (Meaning should have UPPER and lower case letters)
- Contains a mixture of letters and numbers
- Contains symbols (Such as #, ! and so forth...)
- Does not use words found in any dictionary (Such as names)
- Does not use letters or numbers in sequence or in repeated fashion (Like 1111, 1234, abcd)
(Reference: Password Management on UCSB Information Security)
If you have difficulties remembering a strong password, the alternative is to make use of SSH Keys to access the machine.

There are a few tutorials on how to set up fail2ban on Google, and we would recommend using this for at least protecting your SSH access to the machine.
