Ethical hacking terminologies

Ethical Hacking Terminologies 

Following is the list of terms that are frequently used in the field of ethical hacking. If you are not aware of these terms then it would be difficult for you to understand the concept of ethical hacking properly. Thus knowing this will ease your process of going further in this domain.






Vulnerability - 

A weakness, flaw or loophole in a system, network or any device that can be exploited.

Threat - 

A danger that can exploit an existing bug or vulnerability to compromise the security of a network system.

Attack -

An action that is done to extract a sensitive data by getting unauthorized access of a system.






Phishing -

A process where an attacker creates fake website or url which looks like a legit page but it's to trap the user to get sensitive data.

Backdoor - 

A hidden entry point which can bypass the authentication process i.e logins and passwords also known as trapdoor.






Brute force attack -

Permutation and combinations that are used to get into the system which can be done either manually or using some automated tools. It tries different sets of usernames and passwords over and over again until the login is successful.

Denial of service attack -

A malicious attack to either temporarily suspend the service or making resources unavailable to the user also known as DOSing.

Distributed denial of service -

An attack where multiple systems target a server to disrupt the services running on the host machine, which makes the system slow and users won't be able to interact with it.






Firewall -

A network security device which monitors incoming and outgoing traffic and keeping unwanted intruders outside computer system for safe communication between users and system.

Malware -

A malicious software designed by hackers to hack a computer system and steal sensitive information. These goes by various names such as virus, worms, trojans, adware, spyware etc.






Spoofing -

A technique used by attackers to gain unauthorized access to computer, where intruder sends messages to a computer indicating that the message is coming from trusted host.

OSI model

OSI model OSI model is an acronym for Open Systems Interconnection is used to define how data is transferred from one system to another system in a computer network. Now you may ask how a network is formed? If two computers are connected to each other with LAN cables, connectors and Network Interface Card forms a network. Since the designing and infrastructure won't be similar of two computers the OSI model was introduced by ISO(International Organization for Standardization) in 1984 for a successful communication between computers or networks. OSI model consists of  7 different layers 1. Application layer 2. Presentation layer 3. Session layer 4. Transport layer 5. Network layer 6. Data link layer 7. Physical layer Now I'm going to give a mnemonic to remember the OSI model Please-Do-Not-Throw-Sausage-Pizza-Away, easy right? Application layer - Application layer does not include applications like chrome, firefox instead it incl

Phases of Ethical Hacking  In order to be successful in hacking, a hacker needs to follow some steps or you can say phases which involves 5 crucial stages which helps hackers to make a structured ethical hacking attack. Reconnaissance : This is the first phase of hacking   where an attacker gathers as much information as possible. It is also called as footprinting or information gathering. Information that we collect is divided in three groups - network, host, people. There are two types of reconnaissance  - Active & Passive. Active - Direct communication is involved to gather information about the target. Information can be regarding an individual or an organization so anytime if somebody is taking too much interest on you or your background - Be alert! Tools used to scan a network can be Nmap , Hping , etc Passive - Here indirect communication takes place. Information can be gathered using social media websites or public websites. Scanning :  Here an
