The Best Network Firewall Security Solutions for Office Use
Introduction
As more organizations move toward the digital landscape, the threat of cyberattacks is becoming an ever-growing concern for many businesses and government agencies. May it be through hacking, ransomware, or data breaches, cybercriminals are constantly seeking vulnerabilities to exploit.
The Philippines has experienced the profound impact of these threats, with high-profile cases that disrupted online services for overseas Filipino workers and attacks by hackers targeting sensitive data from the Office of the President. These incidents highlight the critical need for strong security protocols. A key strategy to defend against these threats is the use of network firewall security solutions.
This article from InfoBahn Communications Inc. gives a clear overview of firewalls and how they protect networks from cyber threats. It also shares the benefits of different types of firewalls. Keep reading to learn more about the best firewall network protection for your security needs.
Firewalls play a crucial role in protecting digital resources by preventing unauthorized access and cyberattacks. Organizations can select the right solution to address their unique security needs by understanding the different types of firewalls available.
The Best Types of Network Firewall Security Solutions To Protect Your Office
Choosing the right firewall solution is important to protect your network. Below are the most common types of firewalls, which you can deploy based on your office’s specific security needs.
Packet Filtering Firewall
Packet filtering firewalls provide the most basic level of network protection. They inspect each data packet individually, without tracking the entire connection. As a result, they are unable to detect or block more sophisticated threats like malware or buffer overflow attacks. Despite their limitations, these firewalls are commonly used by cybersecurity teams to block harmful traffic and safeguard networks from malicious applications.
For a small business with basic IT needs, a packet filtering firewall is a great option. It can block traffic from suspicious IP addresses or stop employees from accessing unsafe websites by limiting specific ports. While it's a straightforward solution, it offers an important layer of protection for smaller networks.
Stateful Inspection Firewall
A stateful inspection firewall is an upgraded version of a circuit-level firewall. It not only checks each connection but also tracks and verifies them for better security. These firewalls create a table that records important details like IP addresses and port numbers. If a connection can't be verified, it's automatically blocked to stop suspicious activity.
For example, when a user inside a network requests a website, the firewall tracks the connection details. When the website responds, the firewall ensures the response matches the original request. If a packet doesn’t match an active connection, it’s blocked.
Circuit-Level Gateway
A circuit-level gateway acts as a firewall that monitors active TCP connections and sessions. It relies on rules configured by the network administrator to assess these connections, performing checks similar to those of packet filtering. However, this type of firewall does not examine the actual content within the data packets, which means it may not be effective against more advanced or complex malware threats.
For instance, a hospital that stores and manages patient information on its network could use a circuit-level gateway to safeguard this sensitive data. By controlling access and focusing on connection validation, the gateway ensures that only authorized
connections are allowed, helping protect the confidentiality of medical records.
Proxy Firewall
A proxy firewall is an intermediary between internal users and the external network. It intercepts requests, inspects them for potential threats, and then forwards them to the target server if they pass the security checks. This type of firewall effectively hides internal network addresses from external servers, ensuring no direct connections are made, significantly improving privacy and security.
A great example is an employee trying to access a website. The proxy firewall checks the request and ensures it’s safe before allowing access, keeping the internal network hidden from the external and preventing potential attackers from directly reaching the internal network, enhancing security and privacy.
Next-Generation Firewall
As the name suggests, next-generation firewalls go beyond the traditional methods of filtering and blocking traffic. They combine standard firewall capabilities with additional features such as intrusion prevention systems, application awareness, and deep packet inspection. NGFWs can detect and block sophisticated threats like malware, ransomware, and advanced persistent threats. Their ability to analyze traffic at a deeper level makes them an excellent choice for larger organizations or those with complex security requirements.
Imagine two airport security checkpoints. The first one checks if passengers are on no-fly lists and ensures their identity matches the ticket. The second, like an NGFW, does all that, but also takes a closer look at what passengers are carrying, scanning for any hidden dangers. While the first checkpoint stops obvious threats, the second catches those more subtle, harder-to-spot risks.
In the same way, an NGFW looks at network traffic with a sharp eye, ensuring it doesn't miss any threats that might be lurking beneath the surface.
