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) |
...
- Be at least 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 or words)
- Does not use letters or numbers in sequence or in repeated fashion (Like 1111, 1234, abcd)
- Using a password that contains public knowledge information related to you (Such as your address and the like.)
(Reference: Password Management on UCSB Information Security)
...
You should do this from time to time, especially after adding a new application to see what is visible.
Special Cases
Occasionally specific operating systems have some security concerns that are specific to said operating systems. for example users of Raspberry PI's have to worry about disabling the default "PI" user on older Raspberry PI's, something that other operating systems do not have to worry about. Likewise Ubuntu users have to worry about turning on their firewall since it comes turned off by default, see UFW - Basics. While we do have specific pages for the most common issues, it is always good to check with the makers of each operating system for system specific security issues. Please note that Debian, Raspberry and Ubuntu are all non-supported operating systems, all help for them is "best effort". If you install these non-supported operating systems on your personal computer, you are essentially taking responsibility for your own security.
