Cybersecurity shields systems, networks, data, and programs from internet threats. The practice aims to reduce the risk and protect against unauthorized exploitation.
Cybersecurity is crucial as it secures all types of data from damage and theft, including sensitive data, personally identifiable information, intellectual property, and more.
Malware, phishing, password, man-in-the-middle, and crypto-jacking are among the most common cyberattacks.
