Ethical hacking is a process of intrusion into a system or network to identify threats, vulnerabilities in those systems that an attacker can find and exploit, leading to data loss, financial loss, or other major damage. The purpose of ethical hacking is to improve the security of the network or systems by addressing the vulnerabilities discovered during the test.

Ethical hackers can use the same methods and tools used by malicious hackers, but with the authorization of the authorized person, to improve security and protect systems from malicious users. Ethical hackers are expected to report any weaknesses and weaknesses identified during the process to management.
Who is an ethical hacker?
An ethical hacker is an experienced professional who has excellent technical knowledge and skills and can identify and exploit weaknesses in target systems. It works with the permission of system owners. An ethical hacker must comply with the rules of the target organization or owner, as well as the law of the country. Your goal is to assess the security situation of a target organization.
Ethical hacking – wireless hacking
A wireless network consists of two or more devices that are connected to each other via radio waves in a limited area. The devices in a wireless network have the freedom to be on the move but connected to the network and share data with other devices on the network. One of the main points that they are so widespread is that their installation costs are very cheap and faster than the wire networks. Wireless networks are common and can be easily set up. You are using the IEEE 802.11 standard. A wireless router (1) is the most important device in a wireless network that connects users to the Internet.
How routers work
Routers connect a modem (e.g. a fiber optic, cable or DSL modem) to other devices to enable communication between these devices and the Internet. Most routers, even wireless routers, typically have multiple network ports to connect numerous devices to the Internet at the same time. Typically, a router physically connects to the modem over the Internet or WAN port using a network cable, and then physically connects to the network interface card in all available wired network devices using a network cable.
A WLAN router can also be connected to devices that support the standard used via various WLAN standards. The IP address assigned to the WAN or Internet connection is a public IP address. However, the IP address assigned to the LAN or the local network connection is a private IP address. The private IP addresses assigned to a router are usually the standard gateway for the various devices in the network.
In a wireless network, we have access points, extensions of radio links that act as logical switches, so-called distributors. Wireless networks offer great flexibility, but they have security problems. A hacker can spy on the network packets without having to be in the same building in which the network is located. Because wireless networks communicate using radio waves, a hacker can easily discover the network from a nearby location. Most attackers use network sniffing (2) to find the SSID and hack a wireless network. When the wireless cards are converted to sniffing modes, they are called surveillance modes.
Equivalent data protection for cables
WEP (Wired Equivalent Privacy) is a security protocol designed to protect wireless networks and keep them private. It uses encryption on the data link layer that prohibits unauthorized access to the network. The key is used to encrypt the packets before transmission begins. An integrity check mechanism checks that the packets are not changed after transmission.
The benefits of ethical hacking
The main advantage of ethical hackers is that hackers can test a company’s security measures in a controlled, secure environment. These hackers can help companies determine which of their computer security measures are effective, which measures need to be updated, and which measures they find little or no deterrent to dangerous intruders. The data from these tests enables management to make informed decisions about where and how information security can be improved.
When the hackers have fully researched the company’s system, they report a report on the vulnerable areas of the system. These areas can relate to technology, e.g. B. the lack of sufficient password encryption, or in human-based systems, e.g. B. Administrators who assign passwords to unauthorized personnel. Because of these vulnerabilities, management can install safer methods to prevent attackers from exploiting computer networks or the mistakes of their own personnel.
The hackers can also demonstrate the techniques used by unethical intruders. These demonstrations show management how thieves, terrorists and vandals can attack their systems and destroy their businesses. If management has a firm grip on the concepts of “bad” hackers, it can also learn how to prevent these intruders from using these techniques to penetrate their vulnerable systems.
Organizations that handle confidential data need to understand that they are potential targets for a hacker attack. Smaller companies that lack the resources for adequate network security offer seductive opportunities for hackers. The use of ethical hackers can show these companies how vulnerable they are to attack and how devastating the consequences of such an attack can be.
Do you really need ethical hackers?
It is certainly not imperative to use the services of ethical hackers, but traditional security systems have repeatedly failed to provide adequate protection against an enemy that is growing in size and diversity, as experience has shown. With the proliferation of smart and connected devices, systems are constantly at risk. In fact, hacking is viewed financially as a lucrative way, at the expense of organizations, of course. While hardware is easy to protect, information is a bigger problem. It can exist in more than one place, be transported in seconds, and be stolen without realizing it.
Unless you have a large budget, your company’s IT department can prove inferior to hackers’ attacks, and valuable information can be stolen before you know it. Therefore, it makes sense to add a dimension to the IT security strategy by hiring ethical hackers who know the possibilities of real hackers. Otherwise, the company could run the risk of unwittingly leaving gaps in the system open. To prevent hacking, it’s important to understand how hackers think. Obviously, hackers’ approaches are unique and difficult to handle for conventional system security roles. In order to ensure sufficient security in your own company, the hiring of an ethical hacker is essential.
