I am a CISSP, MCSA 2003 Security, CompTIA Security+ and I now have my
sights on a CEH qualification.
In a contemporary society the
importance of gathering, organising and manipulating data is well known.
Virtually every business activity, public and private, requires the storage
of large quantities of information in a format that is simultaneously
readily available and easily updated. Securing the integrity, privacy and
confidentiality of this knowledge is essential. I work in a team that is
responsible for the development and implementation of IT security policies:
- Assess faults and risks in an Information
Technology environment
- Develop a sound ethical Information Technology
security policy
- Establish an Information Technology security
management structure
- Manage and control computer networks with due
regard for Information Technology security
- Build Information Technology security into new
computer software and hardware system implementations
- Prevent and, if necessary in spite of best
practice, manage crises
- Ensure user compliance with agreed security
policy.
1. Put the access
point in the right place
2. Use MAC to stop a hack
3. Change the default wireless network ID (SSID) and hide it
4. Use 802.11i security
5. Remember WEP is not fool proof
6. Use VPN if at all possible
7. Use RADIUS servers if at all possible
8. Simplify your security: integrate wireless and wired policies
9. Don't allow rogue wLAN's to sprout..
10. Communicate
with your Access Points using SSL or SSH.
IT Security advice
- Get a good anti-virus program. Choices are but not
limited to F-Prot for Windows, Norton Internet Security 2004 & McAfee VirusScan 2004
- Get a good two-way firewall.
Zone Alarm
is a popular choice as its free. The firewall that's included in XPSP2 is only a one-way firewall.
Zone Alarm watches activity going on from both inside your computer as well as out on the Internet. XPSP2's firewall is definitely better than not having a firewall at all, but for some people
it's not enough.
- Get a hardware-based firewall or NAT at point of network entry. Why? Because many of us attach un-patched computers while installing, or want to play networked games, or have other reasons for turning off our software firewalls (some software won't work through firewalls). Plus, even if you don't turn them off, provides one more barrier that hackers have to go through. Again, it's about layers of security and not needing to rely on any one security device.
- Keep your systems patched. If you not running the absolute latest software, you're vulnerable (and this is true if you're on Linux or the Macintosh too).
- Run at least one good anti-spyware program like
Adaware
or Webroot's Spy Sweeper
or
Spyware Blaster. That'll make sure that no spyware sneaks onto your system. With XPSP2 I've found that spyware is far less likely to get onto your system, but I've already found one site that has some spyware that gets past XPSP2. So, you'll need to still check, particularly if you visit "high risk" sites (sites that aren't known to you, for instance, or adult sites which are famous for putting spyware on your systems).
- Use strong passwords.
Combine first letters from a phrase. Think
of a song, phrase or sentence, take the first letter of each word, alternate
upper and lower case, and insert creative punctuation and/or a digit.
"Friday the 13th was a scary movie" =
f#13wAsM. However, you can make this password even stronger by using
special characters that look like letters. Never use a single word as a password -- hackers have dictionary cracking tools that can break such passwords.
- Backup, backup, backup. Backup your data regularly. It's amazing how few
people backup their stuff. Hard drives die. Things happen. If you have backups,
you'll be OK even if your machine gets wiped by something.
