What are the basics of ethical hacking?

 Ethical Hacking (basic)


White-hat hackers are also known as ethical hackers and they are professionals with expertise in cybersecurity. They are authorized by the company and certified to hack the systems. They hack systems from the loop to find weaknesses in the system. They never intend to harm the system, rather than try to find out weaknesses in a computer or a network system as a part of penetration testing and vulnerability assessments. well, Ethical hacking is not illegal actually it is one of the most demanding jobs available in the IT Industry. many companies hire ethical hackers for penetration testing and vulnerability assessments. ethical hackers' job is to protect the system network from hackers.








What is hacking?

Hacking is the act of finding the possible entry points that exist in a computer system or computer network and finally entering into them. hacking is usually done to gain unauthorized access to a computer system or a computer network, either to harm the system or to steal sensitive information available on the computer. Hacking is not always a malicious activity, but the term has mostly negative connotations due to its association with cybercrime. hacking is usually legal as long as it is being done to find weaknesses in a computer or network system for testing purposes. 

Types of hacking (BASIC)

we can segregate hacking into different categories, based on what is being hacked. 

here is a set of basic hacking examples: 


Social engineering

Social engineering is a manipulation technique. Using a fake identity and various psychological tricks, hackers can deceive you into disclosing personal or financial information. They rely on phishing scams, spam emails or instant messages, or even fake websites to achieve hacking.


Hacking passwords

Hackers use many ways to gain passwords. The trial-and-error method in which involves hackers trying to guess every possible combination to obtain access. Hackers also use simple algorithms to generate different combinations for letters, numbers, and symbols to help them identify password combinations. Another technique is known as a dictionary attack, which is a program that inserts common words into password fields to see if one works.

 

 Malware hacking

Hackers infiltrate a user’s device to install malware. More likely, hackers will target potential victims via email, instant messages, and websites with downloadable content or peer-to-peer networks.

 

Wireless Networks Hacking

hackers just simply take advantage of open wireless networks. Many people do not secure their Wi-Fi routers, and this can be exploited by hackers driving around looking for open and unsecured wireless connections. This is an activity known as wardriving. When hackers are connected to an unsecured network, they only need to bypass basic security to gain access to devices connected to that network.

 

Website hacking

Website hacking: hacking a website means taking unauthorized control over a web server and its associated software such as databases and other interfaces. 



Network hacking

Network hacking a network means gathering information about a network by using tools like telnet, NS lookup, ping, tracert, netstat, etc. with the intent to harm the network system and hamper its operation. 


Email hacking

Email hacking includes getting unauthorized access to an email account and using it without taking the consent of its owner. 

 

 

The advantages of hacking 

are quite valuable for the following scenarios:

Whenever you need to recover lost information, especially in case you lost your password. 

When you want to perform penetration testing to strengthen computer and network security. 

when to put adequate preventative measures in place to prevent security breaches. 

to have a computer system that prevents malicious hackers from gaining access. 

 

The disadvantages of hacking 

are quite dangerous if it is done with harmful intent. it can cause: 

massive security breach. 

unauthorized system access to private information. 

privacy violation. 

hampering system operation.

denial of service attacks 

malicious attack on the system. 

purpose of hacking 

there could be various positive and negative intentions behind performing hacking activities, here is a list of some probable reasons why people indulge in hacking activities: 

just of fun 

show-off 

steal important information 

damaging the system 

hampering privacy 

money extortion 

system security testing 

to break policy compliance
