How can malware be prevented from infecting a system?

### REPLY:
To prevent malware infections, it is essential to have a strong firewall and intrusion detection system in place. Additionally, implementing strict access control policies and ensuring that all user accounts have strong passwords can help mitigate the risk. Regular vulnerability scanning and penetration testing can identify any weaknesses in the system's security and help patch them before they can be exploited by malware. It is also crucial to have a comprehensive incident response plan in case of a malware outbreak, which includes isolating infected systems, analyzing the malware, and implementing appropriate remediation measures.
