Firewall Network Security
Keep Your Server Safe
Firewall and network security services from Ramdyne Technology LLC protect your network infrastructure and keep online services operational. Our ICSA-certified firewall implementation, which is the most widely accepted standard, monitors and controls both inside and outside access to your network without compromising network performance.
Our Fort Collins IT consulting company recommends businesses have network policies that govern passwords, access to data, and tape/hard disk backup retention. Hardware access, operating systems updates, and current antivirus signature policies should be considered as well. We can help your company directors put together these policies and offer regular onsite audits to ensure your network is secure and in compliance.
What Is Firewall?
A firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted internal network and an untrusted external network, such as the Internet.
The Different Types of Firewalls
Firewalls can be hardware- or software-based and are often used in conjunction with other security measures, such as intrusion detection/prevention systems and anti-malware software. Hardware-based firewalls are typically deployed as dedicated appliances, while software-based firewalls are usually bundled with other security features in unified threat management (UTM) solutions.
How Firewalls Work
Firewalls use a variety of techniques to control network traffic, including the following.
Packet Filtering:
Used to control traffic based on the source and destination IP addresses, port numbers, and other header information.
Proxy Servers:
Used to control traffic based on the content of the packets.
Stateful Inspection:
Used to track the state of the connection and to allow or deny packets based on the state of the connection.
Application-level Gateways:
Used to control traffic based on the application that is being used.
