ETHICAL HACKING

Hai friends,

Here, I welcome you to my blog. This blog is about Ethical hacking – Basic knowledge and Courses.

 

To begin with,

What is Ethical Hacking?

Ethical hacking involves an authorized attempt to gain unauthorized access to a computer system, application, or data. Ethical hacking is also known as White hat Hacking or Penetration Testing.

Ethical hacking is used to improve the security of the systems and networks by fixing the vulnerability while testing and they use the same tools, tricks, and techniques that malicious hackers used, but with the permission of the authorized person.

 

How do Ethical Hackers Work?

The purpose of ethical hacking is to look at the security of a system or network’s infrastructure. An ethical hacker must gain access from the owner and attempt to bypass system security, then find and expose any weak points that could be taken advantage of by a malicious hacker.

Vulnerabilities are typically found in improper system configuration and hardware or software flaws.

Black Hat Hackers

Black Hat hackers, also known as crackers, are those who hack to gain unauthorized access to a system and harm its operations or steal sensitive information.

Grey Hat Hackers

They are not certified, hackers. These types of hackers work with either good or bad intentions. They act without malicious intent but for their fun, they exploit a security weakness in a computer system or network without the owner’s permission or knowledge.

Green Hat Hackers

A green hat hacker is a newbie in the hacking world. As such, green hat hackers may not be as familiar with all the security mechanisms companies or individuals may be using.

Red Hat Hackers

Red hat hackers are again a blend of both black hat and white hat hackers. They are usually on the level of hacking government agencies, top-secret information hubs, and generally anything that falls under the category of sensitive information.

Blue Hat Hackers

A blue hat hacker is someone outside computer security consulting firms who is used to bug test a system before its launch. They look for loopholes that can be exploited and try to close these gaps. Microsoft also uses the term Blue Hat to represent a series of security briefing events.

Elite Hackers

This is a social status among hackers, which is used to describe the most skilled. Newly discovered exploits will circulate among these hackers.

Script Kiddie

A script kiddie is a non-expert who breaks into computer systems by using pre-packaged automated tools written by others, usually with little understanding of the underlying concept, hence the term Kiddie.

Neophyte

A neophyte, “n00b”, or “newbie” or “Green Hat Hacker” is someone who is new to hacking or phreaking and has almost no knowledge or experience of the workings of technology and hacking.

Hacktivist

Stay legal. Obtain proper approval before accessing and performing a security assessment.

Define the scope. Determine the scope of the assessment so that the ethical hacker’s work remains legal and within the organization’s approved boundaries.
