Cybersecurity is the practice of protecting computer systems, networks, and data from unauthorized access or criminal use. It is also known as information technology security or electronic information security. Cybersecurity is essential due to the expanded reliance on computer systems, the internet, and wireless network standards such as Bluetooth and Wi-Fi. The field is of high importance for systems that govern large-scale systems with far-reaching physical effects, such as power distribution, elections, and finance. Cybersecurity can be divided into several categories, including network security, application security, endpoint security, data security, identity management, cloud security, and infrastructure security.
To improve cybersecurity, it is essential to recognize the risks and follow basic cybersecurity best practices. Some common methods used to threaten cybersecurity include phishing, malware, ransomware, and denial-of-service attacks. A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe. It is also important to have a strong cybersecurity strategy to provide a good security posture against malicious attacks designed to access, alter, delete, destroy or extort an organizations or users systems and sensitive data.
