Hacking, which has been part of computing for 50 years, is a broad discipline covering a wide range of topics. The first reported hacking took place at MIT in 1960 and used the term ‘hacker.
For non-geeks, here’s a brief introduction. Computer software consists of computer programs. That gives instructions on how hardware should perform specific tasks. Programmers often develop this software. Who has full access to the entire program? Programs are then sold to users with strict rules or protocols. That allows them to access only certain authorized persons (usually with passwords) for security reasons. No one but these authorized persons has access to their use.
How can others gain unauthorized access?
- Original programmers developed the source code and always provided entry points, trap doors, and passwords.
- Previous users are no longer authorized users but whose passwords have not been deleted.
- Other dishonest people want to access the system for the wrong purpose.
- Because there is a lot of activity and business going on through computers, most computers connect through the Internet. Therefore, they are open to accessing different people through the Internet.
- Computers are also vulnerable to malicious software (malware) and virus attacks. So we are leaving them vulnerable to hackers and malware attacks. People who want to hack into the system introduce these ‘virus infections’ and ‘worms.’ And steal information or want to crash the whole system or destroy all the stored data.
As virus attacks on computers prevent by anti-virus software, such as McAfee, etc., companies protect themselves from hacking by employing ethical hackers. The EC Council has defined ethical hackers as “an individual usually employed in an organization. And can trust to try to infiltrate networks and computer systems as a malicious person.” Is a hacker-based?
It refers to the process of detecting vulnerabilities and vulnerabilities in computers. And information systems that mimic the intentions and actions of malicious users.
It is also known as a penetration test or red teaming. That requires them to view the client network as a potential malicious attacker. Then devise the proper security measures to protect customers from attacks.
So why the need for ethical hackers?
- They need to identify and seal all possible locations of access by hackers. That may be individuals or sophisticated software, including ‘bugs.’
- An ethical hacker thinks and acts like an immoral hacker to find and exploit vulnerabilities in simple language. And vulnerabilities in different systems and how to violate them.
- He then devises ways to protect vulnerable points using firewalls and strong passwords—frequent password changes, passwords, encryption, and iris scans or fingerprints.
- They need to block access to the original software programmers and those no longer authorized to log into the system.
- They can also suggest a secure tunnel between the VPN (Virtual Private Network), the computer, and the places visited on the Internet. It uses a VPN server, which can locate anywhere globally, and provides privacy. VPN will work to hide your browsing history or prevent you from spying on it. The VPN will browse you from the server’s geolocation, not your computer’s location, so we remain anonymous.
Data privacy is a serious concern, with most personal data available on the Internet today at affordable prices. Hackers can buy your data. And steal your data using passwords from other sites. Since most people have the same weak passwords for different applications and rarely do Passwords change. They will teach users how to choose complex passwords, where to record or not, and how often they need to change passwords.
