Final answer:
To monitor all software usage and keep systems secure, companies should regularly update software, train employees on cybersecurity, and install antivirus software. These measures ensure updated security patches, educate users on best practices, and provide system monitoring for malicious activities.
Step-by-step explanation:
To keep systems secure, a company can monitor all software usage, secure applications, third-party software, libraries, and dependencies through a variety of methods. Not all options are equal in effectiveness for this specific task. Here are three optimal choices:
- Regular software updates: Applying updates is crucial for security. It ensures that all software components have the latest security patches, reducing vulnerabilities.
- Employee training on cybersecurity: Educating employees about best security practices can prevent security breaches stemming from user error or social engineering tactics.
- Installation of antivirus software: This helps monitor systems for malicious activities and provides an additional layer of defense against the exploitation of software vulnerabilities.
While multi-factor authentication and the use of open-source software are valuable for security, they do not directly monitor and secure software libraries and dependencies as the question specifies.
