A DIY Information Security Source

Q: With all I have to
do in a day, it's really difficult to keep up with security issues. What can I
do?
A: A typical
business's IT department faces installation, hardware and software challenges
every day. Keeping up with the ever-changing world of viruses, intrusions and
security breeches almost impossible for a busy department. It's estimated that
five to 10 million IT professionals are in this situation. They're being called
on to install PCs rather than find a security patch for the latest virus.
According to the e-zine
W2Knews , cyberattacks reached an all-time high in September 2002.
Internet domains within the United States were the most under fire, with more
than five times the number of attacks as the second leading country's domains.
U.S. Web sites attacked included those for the House of Representatives, the
Department of Agriculture, the Department of Education and the National Park
Service, to name just a few.
If these organizations' Web sites are this easy to attack, what does that say
about how easy it is to attack a company's site, a bank's site or a
telecommunications site that we use in everyday business and life in general?
The recently published Draft Strategy to Secure Cyberspace from
President Bush's Critical Infrastructure Board clearly states that each business
or organization needs to take its own appropriate action to protect itself from
the threat of attacks on its information systems. That in itself is a pretty
bold mission statement, one that many IT departments, professionals and whole
companies have put aside. It's not until they have an attack or a security
intrusion that they take this statement more seriously.
The recommended action includes audition systems to find vulnerabilities,
updating systems where security is in place and ensuring that the provided
security services are managed on an ongoing, real-time basis.
One solution for entrepreneurs is information published by
Co-Logic Security Ltd., a small IT security company in New Zealand that has
created a huge database on IT security vulnerabilities and exploits that's
available free of charge. The site targets IT professionals who lack the
necessary knowledge, time or resources. The database contains information on
almost every product (software, hardware, network, security products and so on),
as well as outstanding vulnerabilities, any fixes the suppliers have provided,
very extensive topics folders on anything to do with IT security and more.
The information is organized according to routers and networks, firewalls,
operating systems, databases, applications and so on. Any organization can
access it to read up on the possible vulnerabilities in the products they've
installed as part of their IT infrastructure.
The site keeps track of new viruses and worms that are announced by the major
software suppliers. It actually allows a search on the subject line, or length
of a newly received e-mail attachment, suspected to be a possible virus, even
when the e-mail seems to come from a "trusted friend."
Those who will benefit most from this site are businesses that have Microsoft
products installed; that use mainstream Unix, Linux or Windows operating
systems; that have Web sites; that run accounting and management software; and
that send out newsletters to their customers.
For large and midsized businesses, managed services by a third party
information security firm is usually the answer. Some companies spend an
inordinate amount of time just assessing their vulnerabilities. An audit by a
third party firm can cut this time drastically and move closer to the
implementation of real solutions. Post-audit managed services can then keep up
with all the viruses and attackers that are changing on a daily basis. Even some
large IT firms outsource the security portion of their business. If you treat it
like an insurance policy, your business will be more secure.
