Lesson 5: Enterprise Security
This lesson explores enterprise security technologies and controls that organizations use to protect networks, endpoints, and sensitive data from cyber threats. It explains how firewalls, intrusion detection and prevention systems (IDS/IPS), DNS filtering, data loss prevention (DLP), network access control (NAC), and endpoint detection and response (EDR/XDR) work together to strengthen an organization's security posture. These technologies provide multiple layers of defense that help prevent, detect, and respond to attacks.
By the end of the lesson, you should be able to:
- Explain the purpose and operation of firewalls in enterprise networks
- Differentiate between IDS and IPS technologies and their security roles
- Describe how DNS filtering protects users from malicious websites
- Explain how Data Loss Prevention (DLP) safeguards sensitive information
- Understand the role of Network Access Control (NAC) in securing enterprise networks
- Compare Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR) solutions and their use in threat detection and response
