Cybersecurity is a combination of technologies, processes, and practices customized to protect networks, devices, programs, and data from unauthorized access resulting in damage. Cybersecurity is also known as information technology security. Cybersecurity helps to protect the confidentiality and integrity of computer systems, networks, and data. The main aim of cybersecurity is to protect organizational assets from external or internal threats. An efficient cybersecurity system requires multiple efforts across all the information systems of an organization.
Cyberattacks are not new. Many well-known incidents have occurred in the past such as the attack on the US government of September 11, 2001 and the devastating of Libya’s government in 2011. Some of the most publicized events which involved cyberattacks are the Stuxnet worm and the Sony PlayStation hack which lead to the leaking of sensitive data about Sony Pictures. Other cyber attacks have been used to disable websites, block users from accessing them, or steal personal data from individuals. Cyber attacks are majorly carried out by a range of groups of hackers, criminals, and governments. These groups may be located in any location on Earth, have advanced technical abilities, and may be motivated by the money, political goals, or ideological goals.

What is the difference between pentesting and ethical hacking?
Pentesting is the process of discovering weaknesses in an information system and analyzing the vulnerabilities for effective cyber security protection. Normally, pentesting is performed by penetration testers who are usually employed by enterprises or organizations to examine their data, networks, and networks, focusing on specific vulnerabilities such as remote code execution, unauthorized access, and code obfuscation. Ethical hacking, on the other hand, is an activity in computer network security that allows someone to scan, visualize, exploit, and gain unauthorized access to an information system. For instance, if you are a private individual who would like to test if your website is vulnerable to hacking, then you may consider to become a security consultant ethical hacker.

All these activities have different stages. In security testing, there are a few stages which are : Stage one: Assessing the hardware of a network Stage two: Assessing the software Stage three: Assessing the operational security of the network Stage four: Assessing the Application Security Stage five: Assessing the Identity Access Stage six: Assessing the Cyber Security Solutions.
