HACKER REGULATION

Every hacker must obey orders - orders that have been agreed upon. In contrast to the cracker, cracker do not care about the rulesof origin where its interests are met they are happy without seeingother people suffer. Some hackers rules are as follows:

1. Work ethically.

The word ethical in this context can be defined to work with theprofessionals by taking into account the moral aspects andprinciples upheld. Any who do must uphold the truth and not hideinformation that should be displayed.

2. Respect privacy.

All information obtained during testing of web applications to thepassword should still be kept confidential. Do not disseminateconfidential information to persons who have no interest in theinformation.

3. Not cause the system to crash

One of the biggest mistakes made ​​by people is when they tried tohack a computer system is causing the computer system to crash.This happens because they do not understand the usefulness or thetechnique of existing security tools.
You can easily create DoS conditions on the system while testing.Running too many tests and too fast to do so will cause the systemto be locked. Many security tools that can be used to control how much testing done on the system at the same time.

HACKER ATTACKS ON UNDERSTANDING COMPUTER SYSTEM

Various attacks can happen to your computer system which in lalukan by hackers are as follows:
1. Non-Technical Attacks
Exploitation involving the manipulation of people or users are the biggest vulnerability in a computer or network infrastructure.Exploitation of this species classified in the exploitation of which is social engineering. Social engineering is defined as the exploitation of human beliefs in order to obtain information that is not good. While the other attacks related to information systems is physical, where hackers will break through the buildings, computer rooms and other areas that contain critical information or property. This attack is referred to as physical attacks. Physical attacks can include dumpster diving.
2. Network Infrastructure Attacks

           Attacking network infrastructure is very easy, because many networks can be seen from anywhere in the world through the internet. Here are some examples of attacks against network infrastructure: 1. Connected to a network through a model that plugs into a computer and through a firewall. 2. Exploit the weaknesses of network transport mechanisms such as TCP / IP and NetBIOS. 3. Flooding the network with a lot of demand, create a denial of service (DoS) for legitimate requests. 4. Installing a network analysis tool in the network and take every packet that passes through and remove confidential information. 5. Go to a network via an insecure wireless Configuration is 802.11b.
3. Operating System Attacks
Attacking the operating system more in love by hackers. The operating system consists of many parts that are easy to attack because every computer has a gap that can be used and exploited. Hackers prefer to attack Windows and Linux operating systems because of the people using these operating systems and know a lot about this operating system vulnerabilities. Some examples of attacks on operating systems is as follows: 1. Exploit application-specific protocol 2. Attacking authentication system 3. Through the file system security. 4. Crack passwords and encryption mechanisms.
4. Application Attacks
           Programs such as e-mail server software and web applications are often targeted by hackers. Some examples are as follows: 1. Applications Hypertext Transfer Protocol (HTTP) and Simple Mail Transfer Protocol (SMTP) is often attacked because most firewalls and other security mechanisms dikonfogurasikan to allow full access to the program - a program from the internet. 2. Malicious software (malware) consists of viruses, worms, Trojan horse, and spyware. Malware can create a network and systems to be down. 3. Spam (junk e-mail) to bring a bad effect on the system and place pentimpanan. Spam also carry malware.
