Hence, gaining knowledge about these operating systems will definitely help you in your journey of becoming an ethical hacker. Without Linux, you may find it difficult to gain access to certain servers and look into any possible breach of security.
Database Engine Skills
DBMS is the main essence of managing and creating all databases. Retrieving a database from where all sensitive information is available can put an organization under threat. A business organization can be under intense threat when illegal hackers get into the security and leak sensitive information. Hence, it is necessary for the database of the company to be highly secured. With the familiarity with different database schemas and engines, you will be able to provide help and advice to business organizations to set up a strong and secured database.
Problem-Solving and Critical Thinking Skills
Having knowledge about all the technical aspects of ethical hacking alone is not sufficient. Adding to this, you will also need problem-solving and critical thinking skills in order to become a successful ethical hacker. There is a lot of information that we receive in today’s world. Illegal hackers are continuously looking for new ways to get this data. Hence, as an ethical hacker, you need to think and formulate a master plan in order to tackle such threats. You must find an effective answer for any problem that comes your way. Apart from this, you must even be willing to learn different ways to solve problems and make sure that all security breaches are checked thoroughly. This process needs a lot of testing on devices.
Computer Networking
Computer networking is one of the most important skills that you need to have in order to become an ethical hacker. Computer networking refers to the interconnection between various devices. These are generally known as Hosts, which are connected using various ways to receive/send any type of media or data. Having knowledge of networks like Subnetting. Supernetting, DHCP, among others will help you explore the different kinds of interconnected computers in networks as an ethical hacker. You will even be able to understand the possible security threats that might be created because of this and learn how to tackle these kinds of threats.
Computer Skills
Computer skills refer to the ability and knowledge that allows you to use computers and other types of technology. Generally, the most basic type of computer skill would involve having knowledge about creating presentations, managing computer files, and processing data. However, on the other hand, the advanced type of computer skills would involve having knowledge about running calculations in spreadsheets, programming, and managing databases. In order to become a successful ethical hacker, you must have basic computer skills. Some of these include Enterprise systems, Web, Social Media, Database Management, Email, Spreadsheets, MS office, and so on. A successful ethical hacker would require to become an expert in computer systems.
Basic Knowledge About Hardware
The physical components of a computer include the motherboard, speakers, sound card, graphics card, computer data storage, keyboard, mouse, monitor, CPU (central processing unit), and so on. In contrast, software refers to a collection of information that can be executed and stored by the hardware. Hence, in order to hack software that is controlled by a computer, you must understand the operation of the machine. After which you must gain access to the computer that operates the machine. The machine will then be able to develop a good software security system. However, you need to keep in mind that illegal hackers do not pay much attention to hardware security. Hence, if the hacker has access, he or she will even have the ability to play with it. Therefore, in order to become an ethical hacker, you must have basic knowledge about hardware. This will not only help you understand hardware, but it will also help you understand how BIOS works together, how CMOS works together, how USBs transfer data, how the motherboard works, and so on.
