What is Netowork Security


[1] Netowork Security defined as consist of provision made in underlying computer network infrastructure, policies adopted by the network administrator to protect the network and the network-accessibility resources from unauthorized access and the effectiveness (or lack) of these measure combined together. [1]


Why Important?


1.        Unauthorized Access

Basically, it can refer to a various sort of attacks. The main purpose of these attacks is to access the recourse that your computer should not allow to be visited. For example, a web server, the web master / administrator should not simply give the power of authorization to the unknown person the control the web server. Once the person steal the data or modify the data inside the web server, it may cause some unexpected consequence.


2.        Executing Commands Illicitly

It does refer to an unknown or un-trusted person to execute some illegal commands thought the server machines. Two main classification of the severity of this problem are normal user access and administrator access. The normal user only able to do some limited thing on a system such as read files or enquiry the information only. But the attackers wish that they can make the configuration through insides the server machines as similar as an administrator like changing IP address or putting some unknown script inside the website to cause the machine shut down automatically.


3.        Confidentiality Breaches

Initially we must examine what kind of treat model that we face: what is it that you're trying to protect yourself against? These is quite damaging if some vital information fell into the hand of a competitor, an enemy or the public. For example, if your business confidential information is stolen by another company, then your company will lose the oppoturnity to survive in the market since the competitor knows all the operation and action about yours. Besides that, the new innovation product will be copied by the competitor at the same time, then your company will lose all the profit margin and aslo the competition in the market.


4.        Destructive Behavior

Among the destructive sorts of break-ins and attacks, there are two major categories.


l        Data Diddling.

The attackers try to hack in the database server and modify the data / information inside the machine. The wrong information will be generated to the user and provide a wrong message to the high level management to do wrong decision. For example, the profit amount of daily / monthly sales report is reduced with Zero from 100, 000, 00 to 10, 000, 00 can cause a lot of consequence inside the company.


l        Data Destruction.

The attacker will destroy some vital information or system file inside the machine to cause the machine can not function very well. Or the wrong message will be provided when using the system server. For example, the attackers delete the hardware driver to make the certain hardware lose the function like storage, which use to store the transaction every day.
