What is Hacking?
When we read the word “hack”, we can immediately think of a black screen with endless lines of bright green code, like in the Matrix, but really, what is a hack?
In simple terms, hacking is using computer skills to find weaknesses in a computer or network and then exploit them through unauthorized access to a system or network.
Think of a computer or network as a room. The intruder scans the space outside, identifying all the weak points in that room, such as breaking windows, soft locks, etc., and finds ways to enter that room without triggering an alarm.
Types of hacking
Hacking is mainly divided into five types, depending on the target type:
- Hacking web applications. This type of hack targets applications that require internet use in your browser. It includes email programs, Google apps, shopping carts, online forms, and more.
- System Hacking: This type of hacking aims to gain access to individual computers on the network by cracking passwords, installing spyware on the system, etc.
- Hacking a web server. A web server is a displays web content. Web server attacks can affect websites and users as they are hosted on web servers.
- Hacking the wireless network. This type of hacking includes intercepting wireless communications and traffic from unsecured networks. Hackers can steal sensitive user information, credit card numbers, passwords, etc. All devices built with IoT support, even modern washing machines, toasters, etc., are vulnerable to attacks if not properly secured.
- Social Engineering: Social engineering is very different from others because it requires the use of the social skills of a hacker to manipulate and trick people into revealing their personal information.
Types of hackers
Hackers are divided into four types according to the reason for the hack:
- Black hat: Black hat hackers are also called thieves. They illegally hack into systems or networks with the intent of harming people or organizations. They are a confusing world of information technology.
- White hat: They are also called ethical hackers. They are information security professionals, and their work is entirely legal. They protect computer networks and systems from malicious attacks.
- Gray Hat: As the name suggests, this is similar to the white and black hat. What they do is illegal, but they have no malice. Grey hat hackers are mostly amateur hackers, and they do it for fun.
- Hackers. Hackers use hacker attacks to further their social or political goals. Hacktivism is usually directed against the establishment regarding freedom of speech/information, human rights, etc.
Many legends surround the hacker’s image of a suspicious man sitting behind 20 screens infiltrating the banking system. As we saw earlier, there is a “bad” hack and a “good” hack or ethical hack.
So what is ethical hacking, and how does it differ from the generally accepted concept of hacking? Let’s understand that.
What is ethical hacking?
Let’s go back to the room example mentioned above. The programmer or programmer builds a room to function like four walls, a floor, a ceiling, windows, a door, etc. The black hat intruder will find the slightest weakness in this room that can be exploited and penetrated. Come to the picture.
His job is to find and fix these weaknesses and make the room unapproachable so that the thief can’t get in. In other words, an ethical hacker should think like a black hat hacker, but their work is perfectly legal, you guessed it, and moral.
Process of ethical hacking
- Survey: In the first stage, hackers collect all the necessary information about the target domain name and history, IP addresses, employee information, phone numbers, etc. This stage is also called imprinting.
- Scanning: This step involves scanning every component of the entire target system for vulnerabilities.
- Gaining Access: This is the stage at which hackers break into the target system or network directly without triggering any alarms, using various tools in their places, such as Metasploit, Sn1per, THC Hydra, etc. Once in the system, they increase their access to the supervisor to move around the system freely.
- Maintain Access: At this stage, hackers create a backdoor on the system, creating their vulnerabilities and uploading them to the system to avoid losing access to it.
- Clear the paths: This is standard hacking protocol, in both white and black hats. At this point, hackers remove all evidence of their unauthorized activity on the target system by deleting their history, log files, changing registry settings, etc.
- Accountability: This is the final step in the ethical hacking process and distinguishes it from illegal hacking. The hackers create an account of the process they followed and how the vulnerabilities were discovered and exploited to gain access to them.
Skills needed to learn ethical hacking
The excellent news is a computer science degree to learn an ethical hacker approach. Here are some of the skills required to wear this white hat:
- Basic IT Skills: Basic knowledge of your computer system and which cable to use, if knowledge is sufficient. If you’ve learned how to start the Windows Command Prompt or modify the Windows Registry, you’ve already got a good start!
- Knowledge of basic concepts: You will need to understand basic hacking concepts such as vulnerability assessment, penetration testing, SQL injection, etc.
- Network. Hacking is incomplete without a network. Another essential skill you need to have in your arsenal is knowing the basics and elements of computer networks, including proxies, VPNs, operations like NAT, IP address, etc.
Careers in ethical hacking
As companies become more aware of the need for online security, the demand for cybersecurity experts is so high that it is now one of the most popular and highly paid professions in information technology. So what options do the ethical hacking profession offer?
- Security of financial services. Financial institutions like banks will lose money and the trust of their users if cybercriminals attack them. Therefore, they need the help of ethical hackers to protect their systems and keep users’ trust.
- Security of the wireless network. Wireless networks in public places such as hotels, shopping malls, airports, etc., are usually insecure and easy to copy or intercept. Ethical hackers are essential to secure these networks and ensure that sensitive user information is not stolen or misused.
- Security of business information. All companies using technology are vulnerable to attacks and need the expertise of ethical hackers to protect their web portals, user information, and more from malicious attacks. Other areas where ethical hackers are required include IT companies, information security companies, defence organizations, forensic laboratories, etc.
In the society you mix with different people. Everyone wants to solve any work by using someone or someone else. And for this reason, hacking was launched. That is why they are thinking, stealing and robbery. Hacking is stolen somewhere, robber somewhere, robber somewhere.
The email you use can be hacked at any moment. And that might only be the people around you. Or if you do not use a strong password If the password is strong, then it may be stolen by security congestion or password recovery.
Very few personal information that many people around you know, can also be hacked by your email.
Now password recovery with mobile phone text. Do not think that your mail or any related account will not be hacked. Removing mobile phone SIM is very easy.
Many of us have not been registered with SIM, but many people can not get registration paper when they take the SIM. Lose it And our mobile operators give SIM very simple questions.
For example, how much money has been loaded on your phone, what is FNF number? These are very easy and without logic. Anyone can call the last recharge of the phone, just as you send 10 rupees to another’s SIM, you can only know. It requires little intelligence to know.
Just like public toilets, public computer viruses and malware are admitted. It is risky to go to these places to login to your email or any other account.
Public WiFi: Public WiFi may be a deadly trap. Hackers can command commands on your logged-in sites very easily. These documents can not be kept in any document, which always shows that you are using them. So, logging in to a site with public WiFi is inappropriate. Risky.
You can work as a prevention for yourself safely online. Going to the unwelcome site, opening an account, providing personal information and giving full banking information is at full risk. Think of yourself how hacking is happening and how you deal with it.
