Welcome to the section on Network Security within our Cybersecurity course. This module delves into the critical aspects of securing computer networks and the data they transmit. Understanding network security is essential for anyone looking to build a career in cybersecurity.
Key Concepts
- Firewalls: These act as a barrier between a trusted internal network and an untrusted external network, controlling incoming and outgoing network traffic based on predetermined security rules.
- Intrusion Detection Systems (IDS): These systems monitor network traffic for suspicious activity and alert administrators when potential threats are detected.
- Virtual Private Networks (VPNs): VPNs create a secure and encrypted connection over a less secure network, such as the internet, so that sensitive data can be transmitted securely.
Real-World Applications
Network security is crucial in various industries, including:
- Finance: To protect sensitive financial data and prevent unauthorized access.
- Healthcare: To ensure patient privacy and comply with regulations like HIPAA.
- Government: To secure national security and protect against cyber threats.
