How do cyber security systems protect against malware?

Cybersecurity systems detect and respond to malicious software or malware attempting to infiltrate networks through various methods such as signature-based detection, behavioral analysis, anomaly detection, sandboxing, and threat intelligence feeds. When a potential threat is detected, the cybersecurity system may quarantine the affected system, block the threat from spreading further, alert security personnel, or initiate automated response actions such as disabling network access or shutting down affected systems. The goal is to prevent malware from causing damage, stealing sensitive information, or disrupting network operations.
