Why is computer security considered essential in the digital world?

Computer security is essential because it safeguards against unauthorized access and malicious intent, protecting personal and office-based computer resources from being compromised.

What are the five key rules for ensuring computer security as mentioned in the script?

The five key rules for ensuring computer security are confidentiality, data integrity, availability, control, and audit.

What does the term 'confidentiality' in computer security mean?

In computer security, 'confidentiality' refers to ensuring that information is only available to the intended audience, which includes the privacy of personal or sensitive information.

How can the integrity of data be protected in computer security?

Data integrity can be protected by ensuring that information does not become inaccurate due to unintended changes, which may involve using controls and security measures to prevent unauthorized modifications.

What is the role of 'availability' in computer security?

In computer security, 'availability' ensures that authorized individuals can access the computer and its information whenever necessary, preventing denial of service and ensuring system uptime.

What are some potential losses that can occur due to security attacks on a computer system?

Potential losses due to security attacks include data loss, misuse of computer resources, reputation loss, and identity theft.

What is the recommended approach to securing one's operating system as outlined in the script?

The recommended approach to securing an operating system includes keeping the OS updated, updating software, creating a restore point, installing antivirus and proactive security solutions, backing up the system, using a standard user account, and keeping user accounts controlled and enabled.

How can an intrusion detection system help in network security?

An intrusion detection system helps in network security by monitoring network traffic for malicious activity or policy violations, alerting network administrators to potential threats, and assisting in maintaining the integrity and security of the network.

What is the purpose of a virtual private network (VPN) in computer security?

A virtual private network (VPN) extends a secure and encrypted connection for data sharing over public networks, ensuring data is sent and received securely, which is particularly useful for businesses and enterprises.

What is the function of a firewall in computer security?

A firewall in computer security functions as a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules, acting as a barrier to block unauthorized access.
