Linux Firewall: A Digital Shield
A Linux firewall is a security tool that acts as a barrier between your system and the external network. It monitors incoming and outgoing network traffic, allowing or blocking it based on predefined rules.
Why is a Linux Firewall Important?
Protection Against Unauthorized Access:
Data Privacy and Protection.
Allow specific incoming traffic: Permit only essential services, such as SSH, HTTP, or HTTPS, and only from trusted sources.
Deny all incoming traffic by default: This is a strong security principle that minimizes the risk of unauthorized access.
Monitor outgoing traffic: While less common, monitoring outgoing traffic can help detect potential data breaches or malware infections.
