Security: The Most Important Financial Concept

Security of your financial information is essential, for many reasons. Identity theft is the main issue, in that if someone can get enough information to re-create your identity in some fashion and get credit cards (or worse) in your name, it will create huge issues for you.

Fraud is rampant in our society, and you must be diligent to ensure you are not a victim of this crime.

Paper Security?

The Shredder , as we spoke about on Tuesday is your security weapon for your printed records. Any old financial records must be destroyed (after they are no longer needed, please don’t just destroy records without knowing whether you need them any more), or stored in a safe place until they are no longer needed. The safest place I can think of for saving important financial documents would be either a Safety Deposit Box or a home safe (or strong box). This will secure your printed information.

What kind of information?

  1. Old Tax Forms, with receipts and associated responses from the government
  2. An inventory of your house with it’s estimated value (don’t store that in the house)
  3. Wills
  4. Birth certificates and such
  5. Receipts from Credit Cards, Property Tax Payments, and such (I think the rule of thumb is at least 3 years of that data).

The Key to Computer Security

Damn right you need computer security .

Possible Computer Security Attacks

First whatever computer you are running your Financial Software tools on, must be secured with a password of some kind, that is common sense.

Next if the computer is connected to the Internet (which it most likely is), then it must also have Anti-Virus and Anti-Spy Software, or your data can be corrupted, or worse still your machine can be compromised by:

  • Trojan Horse software that simply replaces parts of your system with it’s own versions which will look for information on your computer.
  • Key Capture software that will simply steal your on line banking password, by logging all the keystrokes you type on your system and sending them to another computer

Yup, this can happen to you, and you need to protect your finances from this kind of attack. There are many others, I am just highlighting the major ones here (there are many, many more attacks out there).

Network Security

If someone can break into your home network, they can get onto your home computers and steal information directly from your system. There are some easy fixes to stop this (or at least slow it down).

If you have a home network and have a home router, please change the password on the router from the factory default and turn off remote administration! You may as well leave your front door open if you have this turned on, and I can’t tell you how many configurations I have run into that are set up this way.

Linksys, has changed their default configuration to FORCE people to change the default password, but on older routers, this is not the case. If you have a router and don’t know what I am talking about, you need to get someone in to set up your network security.

If you have a wireless home network, TURN ON WAP or some other wireless security, and turn off SSID broadcast. Look up War Driving and see what can happen to unsecured wireless home network configurations.

I had an old router who’s security was compromised, and I ended up selling Herbal Viagra for a while (I didn’t make any money on the deal, and I had my Internet access turned off for a week, and only got it back because I plead stupidity about how I had not configured security on my system).

Again, I am only highlighting a few areas, if you aren’t sure, consult the Internet or call someone who knows about this kind of stuff, don’t just hope it doesn’t happen to you.


Inevitably you will want to dispose of either the backup media you have been using for your computer, or even the computer itself and this is where many people’s identities get stolen (if it can happen to F1 Driver Lewis Hamilton, it can happen to you too).

  1. Should you have old floppies around the house and you do not know what is on them, run a powerful magnet over them, or destroy them (with a hammer). You are a hoarder if you do.
  2. If you have been doing backups on to CD’s or DVD’s and you do not need these backups any more, destroy the media (my shredder actually chews up CD’s and DVD’s, so that is where they go).
  3. Your old thumb drives will need to be demolished as well (i.e. hammered to bits).

This media if just thrown out, is insecure and can easily be used to get information about you (especially if they have been used to back up your financial data).

The one computer point people don’t think of is disposal of your computer. Your computer has a hard drive in it, if you simply throw the computer out, the hard disk has all of that information on it about your finances, and whoever picks up the computer now has this information.

Old Computers?

The best thing to do with an old computer is the following, remove the hard drive from the system, and physically destroy it. Either take it apart and smash the platters, go at it with a sledge hammer or something of the like.

If you want to give this computer to someone or donate it, you must find a shop that will WIPE the disk clean or buy software that will do that. This software will overwrite the data on the disks over and over with varying patterns until the only people who might be able to read it is the CIA or CSIS, you can then donate your computer (but I won’t, I will destroy the hard drive by hand, I don’t trust any of this stuff).

Never, ever give a computer away with the hard disk intact, if you have used it for any financial work at all. Even if all you did was order some stuff from E-bay on line, wipe it clean.

Am I Being Paranoid?

You are only paranoid if everyone is not out to get you (hey I am now the Big Paranoid Cajun Man), but seriously, securing your financial data both hard copy and soft copies and the associated software is the most important thing you can do for yourself, and your family.
