What is Cyber Security?


In today's era every one is aware of the term internet and terms related to internet, each one of us uses for some or the other purpose and we should because it consist of huge resources but do you know how much safe you are while using internet? Or details you put in a site is a safe website? Or images, videos or any file that you download is from a trustworthy website?

If you are already aware, well congratulations! because you are one of those people who will keep its data or information secure,but if you don't know from now on you will definitely because you will further come to know how much attention is required while surfing on internet and that is what we call as cyber security.




Cyber security is the practice to protect network, data, device, program, computer from malicious activity, attack or unauthorized access. Cyberattacks mainly focuses on accessing, destroying, manipulating sensitive information to an individual or business for money or any other purpose.


Why is it important?


Cyber Security is important because the organizations collect huge amount of data from different users and store it in a computer or any such device. A specific amount of data could be sensitive which should not be accessed by any third party, to prevent such things from happening in real world it is important to understand the inputs that we give in any website should be secured and legit and the network that we connect in should be privacy protected.


Types of Cyber Security


  • Network Security : 

To secure a computer network from attackers so that the data that is been sent or received from a network should not get disclosed outside a network.

  • Application Security :

To secure a software from any illicit attempt to get access and steal data. A successful software should be designed and deployed properly and the user must update a software whenever it's prompt to.

  • Information Security :

Information should be kept confidential and should maintain the integrity of data every now and then.

  • Operational Security :

Operational security (OPSEC) also known as procedural security is a risk management process. Originally used by military and now becoming popular in a private sector as well which describes strategies to prevent from adversaries from discovering critical operations related data in order to protect sensitive information.

  • Disaster Recovery :
This defines how an organization responds when cyber attack occurs which causes loss of information or data and how an organization restores its information.

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

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

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
