An ethical hacker needs to be a computer systems expert. Computer hacking skills allow one to use computers and computer technology. To become an ethical hacker, you must have the basic knowledge of hacking. Having basic computer skills can help an ethical hacking aspirant be a successful ethical hacker.
The basic computer skills include processing data, computer file management, and creating presentations. Advanced computer skills include managing databases, programming, and doing calculations in spreadsheets. Some of the essential computer skills are MS Office, including all its programs, spreadsheets, Email, Database Management, Social Media, Web, etc.
Linux is a free and open-source operating system based on the Linux Kernel. The source code of Linux can be modified and distributed to anyone commercially or non commercially under the GNU General Public License. The main reason why learn Linux for ethical hackers is its security. Linux is more secure than any other operating system. Although 100 per cent security is not guaranteed for Linux, it has some malware which makes it less vulnerable than any other operating system. Furthermore, it does not require any anti-virus software. Therefore, it is crucial to have Linux skills for hacking.
Programming Skills are another most crucial skill to become an ethical hacker. Programming means “The act of writing code understood by a computational device to perform various instructions.” So, if you want to be an ethical hacker, you need to know the various programming languages used by hackers and the languages required for hacking.
Although there are many programming languages, all are not used for hacking purposes. Here is the list of programming languages used by ethical hackers.
If you are not familiar with these programming languages, it is wise to learn them. Enrol in the Programming Language Courses to learn the programming language used by hackers or get better at programming.
So, with the help of these languages, ethical hackers can quickly locate system and application vulnerabilities.
SQL skills are essential to becoming an effective ethical hacker. SQL is one of the programming languages required for hacking. Also, SQL is a language used to communicate with a database in Cross-platform Web Hacking. The SQL injection is used to bypass weak web application login algorithms, delete data from the database, etc.
An Ethical Hacker needs to master SQL Skills for Hacking. They must:
An Ethical Hacker must have the basic computer hardware knowledge for ethical hacking. Computer hardware comprises the physical parts of a computer, like the central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard, etc.
In contrast, the software is the set of instructions that can be stored and run by hardware. Therefore, if someone wants to hack a machine controlled by a computer, he needs to know about the device or how it works. Then, he has to access the computer that controls the machine. Therefore, having basic Hardware Knowledge is the key to becoming an ethical hacker first. If one doesn’t know about hardware, how will they know how the motherboard works, how USBs transfer data, how CMOS or BIOS work together, etc.? So one must have basic hardware knowledge also to become an ethical hacker.
Reverse Engineering is a method of retrieving a product's architecture, requirements, and features from an analysis of its code. It creates a database of programs and extracts knowledge from it.
Reverse engineering aims to speed up the maintenance work by enhancing a system's understandability and generating the requisite documentation for a legacy system.
Reverse engineering is commonly used in software security to ensure that any significant security bugs or weaknesses are missing from the framework. It helps make a device stable, thereby shielding it from spyware and hackers. Some developers also hack their systems, known as ethical hacking, to recognize vulnerabilities.
