Following is a list of important terms that used in the field of hacking..

Attack

Attack is an organized attempt to cause a person or organization that is done on a system to get its access or harm. For example, a DoS attack is designed to cause a reduction of performance or fully take down a website

Backdoor

Backdoor is also known as trapdoor. Backdoor is a technique to undetectable entry to a system that bypassed security mechanisms. To access the system or its data. A programmer may sometimes install a back door. So that the program can be accessed for troubleshooting or other purposes. However, attackers often use back doors that they detect or install themselves, as part of an exploit.

Brute Force Attack

Brute Force Attack may have a dictionary of all words or commonly used passwords and cycle. Through those words attackers try to bypass the password to gains access to the account. Brute Force Attack consists of an attacker trying many passwords or passphrases with the hope of eventually guessing correctly. The attacker systematically checks all possible passwords and passphrases until the correct one is found. Alternatively, the attacker can attempt to guess the key which is typically created from the password using a key derivation function. This is known as an exhaustive key search.

Cracker

A cracker is someone who breaks into a secure computer system with the purpose to breach or bypass internet security or copyrighted software. A cracker is doing this for profit or sometime it’s done to point out weaknesses of the security.

Bot

Bot is a program that automates an action that allowing an attacker to take complete control over an affected computer for the criminal to control remotedly. It can be done repeatedly at a much higher rate for a more sustained period than a human operate could do it.

Exploit

An exploit is a piece of software, a chunk of data, or a sequence of commands. That takes advantage of a weakness in an operating system or vended application program to compromise the security of a network system.

Denial of Service Attack (DoS)

A DoS attack is any type of attack where the attackers(hackers) attempt to make a server or a network resource unavailable to users from accessing the service. DoS is typically accomplished by flooding the targeted machine or resource with traffic or superfluous requests in an attempt to overload systems and make it difficult or impossible for the users to use them.

Distribute Denial of Service Attack (DDoS)

DDoS is a type of DoS where multiple compromised systems attack a target, such as server, website or other network resource which are often infected with a Trojan and causing a DoS attack.

Keylogger

A keylogger is a software program or hardware device that has the capability to record every strokes on a keyboard without the knowledge of the user. A keylogger can record instant messages,e-mail, and any information that type at any time using the victim keyboard.

Malware

To perform malicious activities when specific condition is satisfied.

It used to gain the unauthorized access to systems. Types of spoofing are : Address Resolution Protocol(ARP) spoofing, Domain Name System(DNS) spoofing and IP spoofing.

SQL Injection

SQL injection is a code injection technique, in which attackers inject malicious codes in SQL(Structured Query Language) statements to manipulate your database revealing information.

Trojan

A Trojan or Trojan Horse is a malicious program that hackers used to remotely, unauthorized access to a victim computer.

Spam
