Security architecture can be defined as the specifications, processes, and standard operating procedures (SOPs) required to protect an organization's IT infrastructure. In order to improve network security and mitigate risks, a series of network devices can be used to control access to networks and resources. In this course, explore how security architectures can be used to enforce security at the network layer. Explore basic switching and routing devices, and discover core functions of a network intrusion detection systems (NIDS) and host-based intrusion detection systems (HIDS). Explore the characteristics and categories of firewall devices, and learn about networks, intranets, and demilitarized zones. Discover the benefits of network segmentation and learn how to segment networks. Lastly, discover how Network Address Translation (NAT) is used to map addresses, and explore how Network Access Control (NAC) can be used to verify compliance using security policies. This course was originally created by Global Knowledge (GK).
