Massive
rise in Internet security compromises
In
1990 252 security incidents were reported to CERT, a major
reporting centre for worldwide Internet security problems.
By 2000 that figure had risen to more than 24000.
In the 1st quarter of 2003 alone 42586 incidents were reported.
Always
on? Always a target!
Because
Internet access costs have plummeted with the availability
of broadband, many businesses are staying online 24 hours
a day. Unfortunately this makes them an attractive target
for hackers and crackers who will exploit an unpatched flaw
in software to gain access and install backdoor programs.
Common
types of attacks
Once
in they can install more programs and packet sniffers; change
permissions and steal passwords; destroy or compromise your
data; prevent you from using your computer and use your system
to launch an attack on others.
Security
breaches are embarrassing and can cause huge financial losses.
Unfortunately
despite being aware of the risks many businesses dont
address the issue of IT security until a core business function
is crippled by a security breach.

Prevention
is better than cure
A
business must be able to operate efficiently whilst guarding
against security threats from both outside and inside the
enterprise. Installing a firewall is one of the defences you
can use against would be attackers.
A
good firewall implementation will meet the challenge of keeping
unauthorised Internet visitors out whilst allowing
authorised users to go about their legitimate business.
It should separate your internal network from Internet facing
mail and web servers and allow you to monitor inbound and
outbound Internet traffic, be alerted to suspicious activities
and block unexpected traffic.
However
no single tool can offer complete protection for Internet
enabled businesses and good security will be a combination
of:
a
thorough security audit
a
well planned and implemented security policy
a
reliable backup procedure and recovery plan
well
informed, security aware staff
regular
patches for existing software
