CompTIA Linux+ #2024 | Firewalls & Monitoring #11

Firewalls & Monitoring | Linux+ XK0-005 certification exam:

There are various Linux firewall options to control inbound and outbound traffic for Linux hosts. Proxy servers, intrusion detection system (IDS) and intrusion prevention system (IPS) solutions, and security information and event management (SIEM) monitoring solutions all play a part in securing the Linux ecosystem. In this course, you will explore IP forwarding and various types of firewalls, including those available in the Linux OS. Then you will learn how to configure firewall settings using iptables and Uncomplicated Firewall (UFW) and you will discover when and how to use forward and reverse proxy servers. Next, you will investigate IDS/IPS, configure the Snort IDS, and find out how honeypots and honeynets can be used to monitor malicious activity. Finally, you will examine how SIEM and security orchestration, automation, and response (SOAR) solutions can be used to detect and remediate security incidents. This course can be used to prepare for the Linux+ XK0-005 certification exam.
