Email Security


  • Email is not encrypted
  • Any information that you send or receive by email can be easily intercepted by malicious hackers
  • Never email any content that you do not want others to view
  • Any information sent using a university owned computer over the university network may be subject to audit and review
  • Email is one of the primary sources of computer viruses
  • The Vernier network appliance implemented by Texas A&M-Kingsville's computing and information services department (CIS) scans all computers to make sure they have Windows updates as well as updated virus protection
  • Most virus protection software does a very good job of scanning all incoming and outgoing emails for viruses
  • Update your virus protection at least weekly

How to Avoid Email Attachment Problems

  • If you are going to use email to send binary files, also known as attachments, try to keep them small
  • Do not send attachments over two megabytes without checking with the recipient first
  • If you are worried about CIS blocking an unknown file type
  • Zip the file prior to sending the attachment (WinZip or 7-zip)
  • Change the three letter extension prior to attaching it to the email and let the recipient know what they need to change the extension to once they receive the file

Files that are Currently Blocked by CIS

  • .bat – batch file
  • .com - Borland Turbo Pascal 3.0x and many others
  • .dll – dynamic link library
  • .gz – gzip compressed archive

Computer Security

  • Make sure that all computers are password protected
  • Ideally, password protection would be handled by the Texas A&M-Kingsville domain
  • Use a good password
  • Combination of UPPER CASE LETTERS, lower case letters, numbers and other non-alphanumeric characters
  • Good Password – Quail4Ever!!
  • Never use your name, social security number, birth date or any other number or word that someone could lookup
  • To change your password on a windows computer that uses the Texas A&M-Kingsville domain, press CTRL+ALT+DEL
  • Select Change Password
  • Configure your computer to automatically download and install windows updates
  • Configure your virus protection software to automatically download updated virus definitions
  • Configure your virus protection software to automatically scan your entire computer weekly
