Firewall protection is a means to safeguard your network from cyberattacks which can compromise your integrity of data and harm your business. Firewalls filter out incoming and outgoing data packets using pre-established security rules. The rules determine if data packets can be allowed or blocked based on various elements of the packet data, including the source, destination and contents. Firewalls check for unauthorised movement of data packets on your private network.

In addition to preventing malicious attacks from getting into your network, firewalls help in promoting privacy, which makes users feel secure when doing online transactions and communicating with your organization. It is crucial to realize that cybersecurity defenses aren’t sufficient. Firewalls can be overwhelmed by DDoS attacks and other types of hacks that exploit of vulnerabilities that are known to be vulnerable.

There are two types of firewalls: software and hardware. Software-based firewalls are offered for computers, tablets and smartphones. Hardware-based firewalls can be integrated into routers and switches. Both types offer different capabilities and features.

Packet Filter Firewall This is a fast and dirty method to block certain traffic by analyzing the IP address and port numbers of the outgoing data packets. It does not maintain a state table, unlike stateful inspection firewalls.

Stateful Inspection Firewall: This type checks if the data packets belong to an existing connection or not. This enables firewalls to identify suspicious packets, and block them from gaining access to a secure network.
