Ethical hacking is like being a good guy in the cyber world. These hackers, also called white hat hackers, use their skills to find weaknesses in computer systems, networks, and apps. They act like bad guys to test security and find problems before real bad guys can cause harm.
This kind of hacking helps keep things safe. It's like checking if the locks on your doors work well before a thief tries to break in. Ethical hacking helps organizations make their digital stuff strong and protect private information. It finds holes in security and suggests ways to make things better.
By keeping up with the latest tricks that bad hackers might use, these good hackers are ready to defend against any new attacks. They help all sorts of areas, like banks, hospitals, and important systems. Ethical hacking makes the online world safer by finding and fixing problems before they cause big trouble.
Introduction:-
We all know that computers and data communication are really important these days. Think about how fast we can watch TV, use phones, and send emails. But there's a problem too. As the internet grows, some people use technology to do bad things. They can hack into systems, steal information, and cause trouble. These bad hackers are often called criminals or bad guys.
But not all hackers are bad. Some use their skills to help keep things safe. They're like the good guys of the tech world. These good hackers, also called ethical hackers, check for weaknesses in computer systems, just like testing a lock on a door. They help businesses by finding problems before bad hackers can cause harm.
The key difference is why they hack. Bad hackers want to steal or harm. Good hackers test things to find problems and fix them. They make systems stronger. Ethical hacking is like a security test to keep data safe. So, it's important to teach computer students these ethical hacking techniques, so they can protect against bad hackers.
Ethical Hacking:-
Think about how many software programs we use every day. Sometimes, without knowing it, our computers can be secretly accessed by hackers. But there's a positive way to deal with this: it's called "ethical hacking." This means good hackers try to find and fix problems in computer systems to make them safer.
A good ethical hacker knows how hackers work. They use steps like figuring out what's on a computer, scanning it, getting inside, staying hidden, and covering their tracks. The internet's security is not very good, and it's getting worse. Ethical hacking is a way to make things better by finding and fixing weak points in systems owned by others.
Ethical hackers might test new software or look for problems in networks of computers. People used to think ethical hacking was all about helping others, but it turns out ethical hackers also help themselves by keeping systems safe, sometimes even for money. The security of a network depends on its weakest part, so ethical hackers play a big role.
Ethical Hackers Activity:-
A) Test from Far Away
Imagine a person trying to break into a company's network from a faraway place using the internet. They need to get past strong barriers like firewalls and filters that protect the company's servers.
B) Test Through Phone Connection
Now, think about someone trying to break into the company's network through the phones that employees use to connect to work. They have to get past the login systems that verify the employees. This kind of test needs coordination with the phone company.
C) Test Inside the Company
This is like when a company employee, who's supposed to have access, tries to break in. They face defenses like internal firewalls, secure servers, and email systems.
D) Testing a Stolen Laptop
Imagine a laptop owned by an important company person gets taken and given to good hackers. They check if it has passwords and important company info. Since people often save passwords on their laptops, good hackers can use it to connect to the company's network with full access.
The Key Logger:-
Think about the term "key logger" to describe a program that watches and records what you type on your keyboard. Most people think of it as software, but it can also be a physical device. The job of a key logger is to secretly keep track of the keys you press.
Some programs use keylogging for good things, like using special keys to do tasks quickly or changing keyboard layouts. But, some key loggers are used for bad stuff, like secretly recording passwords or other private information. Sometimes, people use these programs to watch what others are doing on their computers.
The line between using keyloggers for good reasons and using them to spy on people can be blurry. There's software out there that's meant to help companies monitor what their employees do or to let users track others' activities on their computers. But sometimes, these tools can also be used to steal private info.
Today, many key loggers are sold openly, and some are even hardware devices. So, it's important to be aware of how these things work to stay safe.
Firewall:-
A firewall is like a guard for a private network, like a digital fence. It can be made from special computer programs or from a mix of programs and devices. The job of a firewall is to stop outsiders from sneaking into a private network from the internet.
Imagine the internet as a big, open space, and the private network is like a cozy house inside it. The firewall stands at the door of the house, checking every message that wants to go in or out. It only lets in messages that follow certain rules to keep the house safe from unwanted visitors. If a message doesn't follow the rules, the firewall says, "No entry!"
So, firewalls are like digital guards that watch the messages between the internet and the private network to make sure only the safe ones get through.
SQL Injection:-
Imagine a website like a house with a lock. SQL Injection is like a trick that bad people use to get into the house. They find a way to send sneaky messages to the website's database (like its memory). They do this by typing things into places where you can enter information on the website.
These bad guys can then steal important stuff like usernames and passwords. They can also mess up the website, change things around, or even shut down parts of it. It's as if they broke into the house, messed up the rooms, and stole valuable things.
This happens when the website doesn't check the information you put in carefully. If the website doesn't double-check, these bad messages can trick it into doing things it shouldn't. This is really dangerous because the bad guys can get private info like credit card numbers. According to reports, SQL Injection is a big problem for websites and needs to be stopped to keep things safe.
Conclusion:-
In conclusion, ethical hacking is like being a good superhero in the cyber world, protecting systems from bad guys. These good hackers called white hat hackers, find and fix computer problems to keep them safe. They test networks from far away, through phones, and inside the company. They're like security experts making sure everything works well.
Key loggers are sneaky programs that can watch what you type and be used for good or bad. Firewalls act like guards for private networks, ensuring only safe messages get in and out. SQL Injection is a tricky way terrible people try to get into websites, but we need to stop them to keep our information safe. All these things help us understand the digital world better and stay protected.
