Security Tips & Threats

Security Tips: General

Password Management

  • Longer passwords are more secure; try selecting passwords that are 8 characters in length.
  • Change passwords periodically
  • Never give a password to anyone else. This includes the system administrators, they will never need a users' password to do their job.
  • Good Passwords
    • using both upper and lower case letters *
    • using numbers and/or special characters *
    • using the longest password allowed (usually 6 or 8 characters)
    • easy to remember so it doesn't need to be written anywhere.
      (* not supported on every operating system)
  • Bad Passwords
    • the password matching the userid
    • the names of people, birthdates, or any personal information that may be publicly obtained.
    • words found in dictionaries (including foreign languages)
    • short passwords
    • bad passwords spelled backwards
    • simple letter substitution (ie: using '3' for 'e' or '0' for 'o')
    • any password that is written somewhere

An easy way to select a good password is to use an acronym that is easy to remember. Then mix the case and add a number or special character. "I hate all this password stuff" could result in 'Ihatps!'. Of course, this is a sample and since it's shown here it should not be used. It is no longer a secure password.

File Access

  • Never set the other write permission on any file.
  • Only turn on the other read or execute permission on a file if you want the file to be public readable.
