I need some recent computer security stats for a presentation.
Specifically I am looking for the following information:

How many companies in the US (number or %) were the victims of
computer crime in 2004? (including viruses, hacking, fraud, etc.).

I have plenty of data for 2003 and 2002. I just need it for 2004.

Please site your sources ? both the site you pull from and the
original source if available.

Thanks,

Mike

vadesign-ga,

I'll do you one better...statistics for 2004 AND 2005!

According to the recently-released 2005 annual report on computer
crime issued jointly by the FBI and a private firm,CSI, unauthorized
computer use in 2005 was reported at 56% of US companies and other
institutions, up slightly from 53% in 2004.

However, the category of "web site incidents" skyrocketed in 2005,
with 95% of institutions reporting 10 or more incidents (as opposed to
only a small number reporting that many incidents in 2004, although
89% had reported from 1-5 incidents in 2004).



The full report is available here:

Here are some relevant excerpts from the report, titled:


TENTH ANNUAL
CSI/FBI
COMPUTER CRIME
AND SECURITY SURVEY


===============

Frequency, Nature and Cost of
Cybersecurity Breaches


Turning to figure 13 (page 11), we can see that the decline in overall
frequency of (successful) misuses of computer systems that began in
2001 may have come to a halt this year. The percentage of respondents
answering that their organization experienced unauthorized use of
computer systems in the last 12 months increased slightly from 53
percent last year to 56 percent this year.

===============




The report also notes a dramatic increase in what it calls "web site
incidents".  An amazing 95% of organizations reported 10 or more web
site incidents:



===============

One of the most dramatic findings from this year?s survey is the
exponential increase in Web site incidents (figure 15). The 2004
survey found that 89 percent of those organizations responding
experienced between 1 and 5 Web site incidents, but only 5 percent
experienced more than 10 such incidents. As evidenced by figure 15,
this year there was a total flip with 95 percent of responding
organizations experiencing more than 10 Web site incidents and a mere
2 percent experiencing between 1 and 5 such incidents.

Nice work! Thanks so much for the quick and excellent information.

You're quite welcome...and thank you for the very kind feedback.

Without in the least impinging on the value, quality, accuracy of
Pafalafa's answer, it can be asked if the remarkable increase in
computer crime statistics results from the more active response by the
companies.

What remarkable increase did you have in mind?  Overall, the increase
in unauthorized use was from 53% in 2004, to 56% in 2005.

Thanks again. I'm sure there are variables to consider but you gave me
exactly what I needed Paf. Again, great job!

Just that, Paf, over 50% increase in two consecutive years, but I will
admit that I come from a conservative (finance) background, in which
such growth figures are unusual.  The web is no doubt growing in a way
to make that not so remarkable.
But I was also looking at the information in your paragraph  ("One of
the most dramatic findings from this year?s survey is the exponential
increase ...")
Pax!
You found the right data.  I was not suggesting that it was incorrect.
