Have you ever seen any heist movies where a person with a nerdy look, wearing spectacles does intense coding on his laptop to break into an organization’s system to either steal their information or disable an alarm or even change any previously existing data so that he and his fellow companions can get through with their heist plan? The role that the nerdy guy performs is of a hacker and the task that he does is hacking.
Hacking and Hackers
But, what exactly is a hacker or hacking?
Hacking is a task carried out to misuse data by attempting to break into a computer system or network. The main aim of hacking is to gain unauthorized access to a computer’s information by finding its security weakness and fracturing it to steal data, corrupt files, manipulate them, or abuse the information.
A person who does hacking is a hacker. Hackers are usually highly intelligent people with great coding and computer skills who try to exploit the weak points of a computer system or find loopholes in its security to gain unofficial access to its information.
One requires tremendous intelligence and knowledge to break into a system compared to creating it therefore hackers have a great amount of expertise in this area.
Hackers can be broadly classified into 3 types namely, white hats, black hats, and grey hats.
White hats are professional hackers who gain access to a computer system or network to find loopholes in the system’s security and try to fix them to make the system more hack proof. They generally hack the system of the organization they are a part of.
Black hats usually hack a system to gain unauthorized access for their benefit. Their primary objective includes destroying data, stealing it, or manipulating it. They can even block the permitted users from accessing the system. Cracker is a term often used for black hats.
Grey hats are curious hackers who break unofficially into a computer network or system and look for potential flaws in the system. The difference between blacks hats and grey hats is that the latter informs the system administrator or owner about the flaws or defects he finds.
Hacking is an illegal activity, a cybercrime, which can cost a loss of millions of dollars to an organization. All types of hacking are unlawful except for the hacking done by white hats.
The hacking done by white hats is called Ethical Hacking.
What is Ethical Hacking?
Ethical hacking is an authorized endeavor to compromise a computer system’s (or network’s ) security and gain unauthorized access. The principal aim of ethical hacking is to find potential loopholes and weaknesses in a system that can be a threat to the system’s safety in the future. It is also known as penetration testing.
Unlike other types of hacking, Ethical hacking is approved and planned out by an organization that wants to do a security check on its system. They permit their cybersecurity engineers or white hats to carry out such activities so that their system defense is up to date. Ethical hackers find vulnerabilities in a system and prevent other malicious hackers from breaking in.
Roles and Responsibilities of an Ethical Hacker
There are a few rules which an ethical hacker must abide by:
- They must sanction authorization from the organization whose system they are hacking into. Any activity performed should be first approved.
- Their plan of action should be presented to the organization beforehand.
- They must agree to maintain confidentiality and protect the privacy of the organization.
- Their discoveries and reports must be transparent and the organization should be informed of every finding.
- After getting the results they must delete all traces of the hack.
Following all the above-mentioned points is mandatory for an Ethical hacker to perform hacking legally.
