Computer skills

Computer skills seem like basic ones, but one of the most vital skills to consider. Having thorough knowledge and ability to handle operating system, networking parameters, windows operating software, and related technology is essential.


The cryptography concept converts the textual message into a non-readable format, making it inexplicable for hackers to decode it. An ethical hacker uses cryptography to keep communication between employees safe and secured.

Database Skills

DBMS is the core of managing all the databases. Illegal access to the organization’s sensitive information can cause a tremendous threat to the organization. That’s why an ethical hacker should possess knowledge of various data schemas and database engines, which in turn helps the organization develop a robust database management system.

Reverse Engineering

Reverse engineering ensures that the system is free of security flaws and vulnerabilities. It also makes the system robust by safeguarding the organization’s vital information from spyware and hackers. Reverse engineering helps to improve the system’s understandability and helps to prepare necessary documents as well.

Programming Skills

Programming skill is one of the essential skills to consider. The word” Programming” involves writing code to perform various activities. Here are a few programming languages for ethical hackers C, C++, SQL, PHP, Ruby, Perl, and so-on.

Wireless Technologies

Ethical hackers use wireless technologies such as WPA, WPS, WEP, etc., to safeguard the systems from sharing sensitive information through an invisible source.

Problem-Solving Skills

In addition to the above-mentioned technical skills, an ethical hacker should be a pro-active problem solver and possess exceptional thinking capability. They must be aware of all the essential techniques to check security breaches.

The reconnaissance phase is also known as footprinting and information gathering phase. Here, an ethical hacker can gain valuable information about the organization, which includes collecting old passwords and employee names through active or passive techniques.

Footprinting is categorized into two types:

Active – Direct interaction to collect information about the target

Passive- Trying to gather information about targeting without direct access.


The scanning process involves collecting active information from a network or a target system for the issues which can be easily exploited. A few of the tools used for the scanning process are Nexpose, NMAP, and Nessus.

Gaining Access

At this phase, the hacker has all the essential information required to carry out the attack using various tools and methods.

Maintaining Access

Maintaining access is one of the essential steps. Even if the hacker restarts/shut down the system, the connection remains the same. This phase involves getting access to the target until he finishes the accomplished task.

Clearing Tracks

The final step in the ethical hacking process is to clean all the hacking traces as no thief wants to get caught red-hand. The process involves modifying/deleting the logs, deleting the folders, and uninstalling the applications.


I hope you have enjoyed reading this post on Ethical Hacking Tutorial. The need for ethical hackers has gained prominence globally with the surge in security threats. Incorporating a robust approach to implement security policies would surely help organizations shield their sensitive information and fine-tune the gaps that lead to the compromise of the organization’s security.

Businesses operate in a structured and complex environment involving security policies, prevailing technologies, and interactions. Thus, accessing the systems holistically and organization security must be monitored regularly for its efficiency.
