Cybersecurity can be summarized as efforts aimed at preserving the confidentiality, integrity, and availability of computing systems. It's the practice of affording security to networks and systems to protect them from cyber attacks.
Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.
Cyber attacks have been on the rise and are targeted at accessing, modifying, or deleting data, money extortion, and the interruption of normal services. Cybersecurity is of great concern to today's businesses since there has been a high adoption of information technology to achieve efficiency and effectiveness in business operations. The current business environment is such that there are many devices, systems, networks, and users. All these are targeted by cyber criminals, and multiple techniques have been devised and used against them. Cyber attacks are only becoming more effective and sophisticated. Therefore, cybersecurity is becoming a survival mechanism rather than a luxury for many businesses. Cybersecurity has multiple layers, which cover devices, networks, systems, and users. These layers are intended to ensure that these targets are not compromised by attackers. In organizations, these layers can be compressed into three categories: people, processes, and technology.
