Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.

Cyber Security  lifecycle consists of five distinct stages, each with its own tasks:

1. Assessing : This stage, we look at the actual performance of the organization's controls and compare it with the desired or potential level of performance.
2.  Defining a Security Strategy : A strong security strategy does not priorities security and impede productivity.
3. Developing a Framework : In this stage, we look at the organization's ability to meet a variety of regulatory frameworks and data protection standards.
4.  Implementing Controls : Controls may include a combination of firewalls, intrusion prevention systems (IPS), security information and event management (SIEMs), security operations centers (SOCs), endpoint detection solutions, vulnerability management, security awareness training and much more.
5. Auditing :  In order to successfully implement a cybersecurity strategy, or information security management system (ISMS), it is essential to carry out a systematic review of the implemented strategy and controls.
