Preventing Workstation Intrusions
Securing
desktop workstations is a critical component of any IT infrastructure in order
to prevent unauthorized access to sensitive information and resources. Since
default desktop configurations are not secure, you must configure new
workstations to reflect your security requirements and reconfigure them as your
requirements change.
Physical Security
1. Set the boot order to access the appropriate hard
disk first to prevent unauthorized users from accessing you system via a boot
floppy or CD.
2. Set a boot password to prevent unauthorized access
to your operating system.
§
Changing the boot
order and setting a password can be set in the BIOS. Contact the Help Desk for
assistance.
3. If possible, physically lock the case of the
machine.
4.
Secure sensitive
data stored on removable storage media (e.g. floppy disk).
Operating System Security
1. Do not install unacceptable or unnecessary
software, especially from unknown sources.
§
Absolutely no file
sharing programs (Kazaa, Limewire,
Bearshare, etc.), chat software (AIM, ICQ, MSN Messenger,
etc.), or IRC clients.
§
Unnecessary programs
such as Gator, Bonzai Buddy, Webshots,
GoZilla, or Weatherbug can
hog system resources or pose a potential security risk.
2. Install the latest patches, service packs, and
updates.

3. Install and maintain anti-virus and firewall
software. Update virus definitions once a week.
§
Anti-Virus: McAfee
VirusScan, Norton Antivirus, Kaspersky
Anti-Virus
§
Firewall:
ZoneAlarm, Sygate Personal
Firewall, Norton Internet Security
§
Anti-Trojan:
Tauscan, The Cleaner, TDS-3 Trojan Defense Suite
4. Practice safe web browsing and email management.
§
Disable ActiveX in
Internet Explorer. For extra security disable Java as well.
§
Only download
attachments if you know exactly what it is and trust the source.
5. Encrypt sensitive data sent over a network. It is
recommended to use SSH and SFTP instead of Telnet and FTP.
§
Windows:
SSH Secure Shell, PuTTY
§
Mac OS:
MacSFTP, MacSSH (Classic), JellyfiSSH (OSX), NiftyTelnet SSH
(Classic)
6. Set appropriate passwords. Use at least 8
characters and try to use a mix of characters (mix uppercase and lowercase
letters with digits). Change your password every 60 days.
7. Set a screensaver password to restrict access to
your system while you are away.
8. Rename the default Administrator account and
disable the Guest account.
