Cybersecurity is the practice of protecting computer systems, networks, and data from cyber threats such as hackers, malware, phishing attacks, and data breaches. It involves implementing measures such as firewalls, encryption, intrusion detection systems, and security protocols to safeguard digital assets and information. Cybersecurity professionals work to identify vulnerabilities in systems, assess risks, and develop strategies to mitigate them. With the increasing frequency and sophistication of cyberattacks, cybersecurity has become a critical concern for organizations across industries to protect sensitive data.
