What is Firewall Defined?
In simple terms, a firewall is a security system that monitors and controls incoming and outgoing network traffic based on predetermined firewall rules. It acts as a barrier (or wall) between a trusted internal network and untrusted external networks, such as the internet. It’s called a firewall in computer network because just like a physical firewall stops the spread of fire in a building, it also stops the spread of malicious data from entering or leaving your systems.
How It Works
A firewall works by filtering traffic. It’s network allows or blocks data packets based on set configuration rules.
Here’s a quick flow of how firewall:
- Data packets arrive at the firewall.
- The firewall checks each packet against a set of rules (e.g., allowed IPs, ports).
- If the packet meets the rules, it’s allowed; if not, it’s blocked.
You can set these rules based on application, port number, IP address, or protocol. Some firewall rules examples include:
- Block all incoming traffic except ports 80 (HTTP) and 443 (HTTPS).
- Allow traffic only from specific IP ranges.
Types of Firewalls
There are several types of these depending on the protection level you need:
- Hardware Firewalls: These are standalone devices placed between your network and the internet. So essentially, can firewall be hardware? Well, yes!
- Software Firewalls: This type of firewall can be installed on individual computers. (Is firewall a software? Yes, it can be.)
- Cloud-based Firewalls: Offered as services by providers like AWS Firewall and AWS Network Firewall.
Advanced setups may also include:
- Firewall UTM (Unified Threat Management): A multipurpose firewall that includes antivirus, intrusion prevention, and more.
- Firewall DMZ: Places certain public-facing services in a separate zone to isolate threats.
- Firewall and Proxy Settings: These are essential for managing content filtering and traffic control.
Common Firewall Issues
Firewalls are essential, but they can cause problems if not configured properly: Here are some common issues
- Blocking legitimate traffic
- Request errors
- Firewall zero hour attacks (new malware not yet recognized)
- Problems due to misconfigurations
- Issues connecting firewall to switch
Pro tip: Make regular backups and always test after rule changes.
What Firewall Level Should I Use?
This depends on your risk profile:
- Basic protection is enough for personal use or a firewall for home network.
- Mid-level systems are great for small businesses looking to save cost.
- Enterprise-level may require high-performance solutions like Fortinet, Check Point, or WatchGuard.
