The importance of Network Security
Networks are very vulnerable to many types of attacks. These can be mitigated but not prevented and it’s different for every single company. Network Security must have a specific goal for the enterprise that must be achieved. If your database contains thousands of credit card numbers, then authenticating and authorizing access to protected servers and protecting the whole network from all intrusion attempts is necessary.

They are not malicious; they can often be very helpful. They find potential problems in software that could be fixed in order to make it fulfill its purpose. Crackers not try to gain knowledge but they try to gain wealth. They want what others have and use technology to obtain it. If they cannot obtain a given source, they try to make nobody can get it either. This is known as denial of service attack. They are people from whom you must try to protect your resources.
