Firewall Certification & Courses, Careers, Exams, Online Classes

Firewall courses teach you to safeguard networks and systems using advanced security technologies. These courses cover the fundamentals of firewall management, such as packet filtering, stateful inspection, and advanced configurations with tools like pfSense, Cisco ASA, and Palo Alto Networks. Firewall courses blend theoretical knowledge with practical hands-on labs, allowing learners to effectively implement and manage security protocols.

What is a Firewall?

A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. In layperson terms, you can consider it a barrier between your trusted internal network and untrusted external networks, like the Internet. Modern firewalls combine hardware and software components to filter traffic and block malicious actors while allowing legitimate traffic to pass through. If you want to learn more about firewalls, read the What is a Firewall article.

Types of Firewall

There are mainly these seven types of firewalls:

Firewall Type	Description	How It Works
Packet Filtering Firewall	Inspects individual packets at the network layer based on pre-defined rules (IP, port, protocol).	Uses an access control list (ACL) to allow or block packets.
Stateful Inspection Firewall	Tracks active connections and inspects traffic based on state and context.	Maintains a state table to monitor ongoing sessions.
Proxy Firewall	Acts as an intermediary between internal and external networks, analyzing application-level traffic.	Creates a separate connection to proxy requests on behalf of clients.
Next-Generation Firewall (NGFW)	Integrates traditional firewall functions with advanced features like intrusion prevention system, and application awareness.	Combines packet filtering, stateful inspection, and deep packet inspection (DPI).
Cloud Firewall	Hosted in the cloud, designed to protect cloud-based resources and services.	Filters traffic entering/exiting cloud environments, often using virtual instances.
Web Application Firewall (WAF)	Focuses on monitoring and filtering HTTP/HTTPS traffic to protect web applications from attacks like SQL injection or XSS.	Inspects traffic to web applications and blocks malicious requests.
Unified Threat Management (UTM)	All-in-one device offering multiple security features, such as antivirus, content filtering, and intrusion detection system.	Combines multiple tools into a single appliance for simplified management.
