Firewall Programs

A firewall program acts as a barrier between your computer or network and the vast sea of data flowing through the internet. Its primary function is to monitor and control incoming and outgoing network traffic based on predefined security rules. By doing so, it helps prevent unauthorized access to your system and protects against external threats, such as hackers and malware.

A firewall can be either hardware-based or software-based. Hardware firewalls are physical devices usually installed between your network and the internet. They filter network traffic based on preconfigured rules. On the other hand, software firewalls are programs installed on individual computers or devices, providing protection specifically to that device.

A firewall program works by analyzing network packets and determining whether they should be allowed or denied access. It examines factors such as the source and destination IP addresses, ports, protocols, and the type of packet. If the packets meet the defined criteria, they are allowed through the firewall. If not, they are blocked, ensuring that only legitimate traffic enters or leaves your network.

Types of Firewall Approaches

Firewall programs can employ different approaches to protect your network:

• Packet Filtering Firewalls: This type of firewall analyzes packets based on predefined rules and filters them accordingly.
• Stateful Inspection Firewalls: These firewalls maintain a complete record of current network connections and use that information to determine the legitimacy of incoming packets.
• Proxy Firewalls: Proxy firewalls act as an intermediary between your network and the internet, intercepting requests and validating them before forwarding them.
• Next-Generation Firewalls: Next-generation firewalls combine traditional firewall functionality with additional layers of security, such as intrusion prevention systems (IPS) and application-level controls.

The Relationship Between Antivirus Programs and Firewall Programs
