Cybersecurity measures protect against malware through a combination of software, hardware, and best practices aimed at preventing unauthorized access and mitigating threats. These measures include the use of antivirus software to detect and eliminate malware, firewalls to block harmful traffic, and intrusion detection systems (IDS) to monitor networks for suspicious activity. Regular software updates and user education about recognizing phishing attempts further enhance protection, creating a multi-layered defense strategy against malware attacks.
