What You Need to Know About Firewall Protection


Firewall protection is a method to safeguard your private network against cyberattacks that could compromise data integrity and threaten your business. Firewalls filter outincoming and outgoing data packets using established security rules. The rules determine if data packets are permitted or blocked based on various elements of the packet data, including the source, destination and contents. Firewalls monitor the unauthorised movement of data packets within your private network.

Firewalls not only prevent malicious attacks from getting into your network but also promote security, making customers feel secure when they do online transactions or interact with your company. It is crucial to recognize that cybersecurity protections aren’t enough. Firewalls are vulnerable to DDoS attacks, as well as other attacks that exploit known vulnerabilities.

There are two primary types of firewalls: hardware and software. Software-based firewalls can be installed on computers as well as mobile devices like tablets and phones. Hardware-based firewalls are integrated into routers or switches. Both types offer different capabilities and features.

Packet Filter Firewall: This type is a quick and dirty method to block certain traffic by looking at the IP addresses and port numbers of the outgoing data packets. It doesn’t keep a state table, like stateful inspection firewalls.

Stateful Inspection Firewall: This type determines if the data packets are connected to an existing connection or not. This enables firewalls to detect suspicious packets and stop them from entering a protected network.
