Im also going to create a tutorial based on this one aswell as my other topic.

ATTACKS on corporate computer systems from hackers on the Internet pose a serious risk to businesses. The advent of digital economies and the increase in the number of transactions being conducted over the Internet on a daily basis exposes companies to continued security risks, says Eric Levenstein, partner at Werksmans Attorneys.
"Attacks on corporate data come from some surprising quarters," he says. "Teenage hackers, usually blamed for compromised security, account for just 7% of reported violations, while infiltration by a company's competition peaks at 39%. Even more surprising is that most of the hacking on a network is done by trusted employees. In addition, the potential for private and confidential information being intentionally or inadvertently distributed to the outside world is a real possibility."
The better approach is to secure access from the Internet to the internal network of a company. Here access control devices include firewalls, which can take a number of forms.
Advanced firewalls provide detailed logs of incoming and outgoing traffic and have the ability to control this traffic per individual user. Once the network access has been controlled, the content flowing into a network must be controlled.
Often legitimate traffic may contain illegitimate content in the form of viruses or software. This can allow an external hacker to pass a program into the network so that an attack can be staged from the inside. It is relatively easy for hackers to eavesdrop on Internet traffic and obtain passwords and confidential information. Encryption, where data is scrambled using complex algorithms, can be used to solve this problem.
"In many cases the Internet is safer than private networks because these networks rely on being hidden from hackers," says Levenstein. "This is not always true and should a hacker connect to a private network via dial-up connections, the barriers that prevent penetration are limited."
a terrorist group was all the more embarrassing.
Many technology experts welcomed the intrusion as proof that governments should get more involved in monitoring the Internet.
What is clear is that businesses and companies carrying out trade on the Internet will not only have to contend with technical issues and security fears, but will also run the risk of surfing into national, and in some instances international, legal problems.
