Every business network is different, just as every network firewall security configuration is different. Our expert IT consultants understand that there is not one single solution for the optimal security setup for every company. We will work with your team to ensure that an effective, achievable strategy that is configured to your organization’s unique needs, operating systems, and application control protocols.
Companies are being faced with a new type of criminal hacker, one who is targeting their corporate knowledge. A managed application firewall protects your corporate network from web attacks and provides many other services as well. Our managed application firewall is operated by security specialists who are always up-to-date on the latest attack patterns.
Today, the most dangerous cyber criminals are active in industrial espionage where they steal patents, high-tech developments and other valuable corporate knowledge. With ever-changing attack methods and an almost unlimited time budget, they try to break in online to internal networks to access the information they are looking for. The only way to quickly identify cyber attacks and be able to launch countermeasures is to work around the clock to monitor, correlate and separately analyze the network and security incidents occurring in your systems.

Different Types of Network Security Firewalls

Implementing network firewall security can come in several different forms spanning hardware and software. These special devices restrict incoming and outgoing network traffic using specifically coordinated criteria, keeping any unauthorized users out of your secure network. Firewall Hardware A hardware firewall is installed between your company’s network and the Internet to protect the systems inside – typically a router. For example, if a hacker tries to access your systems from the outside, your hardware firewall should be able to block it. Firewall Software A software firewall only protects the device it is installed on. While computers may come preinstalled with certain antivirus software firewalls, they often don’t have the same protection as something more robust. If an employee were to accidentally click on a phishing email, a software firewall should stop the malware in its tracks. The best enterprise firewall protection uses a combination of hardware and software firewall security. The vulnerability of one alone is too great of a risk for enterprises and SMBs to take when it comes to data security. Using both a wired or wireless router (hardware firewall) and anti-virus and firewall protection programs (software firewall), businesses can reduce as many vulnerabilities as possible. Types of Firewalls The National Institute of Standards and Technology (NIST) 800-10 divides firewalls into three basic types:
  • Packet filters – On the Internet, packet filtering is the process of passing or blocking packets at a network interface based on source and destination addresses, ports, or protocols. The process is used in conjunction with packet mangling and Network Address Translation (NAT). Packet filtering is often part of a firewall program for protecting a local network from unwanted intrusion. In a software firewall, packet filtering is done by a program called a packet filter. The packet filter examines the header of each packet based on a specific set of rules, and on that basis, decides to prevent it from passing or allow it to pass.
  • Stateful inspection – Stateful inspection, also known as dynamic packet filtering, is a firewall technology that monitors the state of active connections and uses this information to determine which network packets to allow through the firewall.
  • Proxys – A proxy server is a dedicated computer or a software system running on a computer that acts as an intermediary between an endpoint device, such as a computer, and another server from which a user or client is requesting a service. The proxy server may exist in the same machine as a firewall server or it may be on a separate server, which forwards requests through the firewall.
Although, these three categories are not mutually exclusive as most modern firewalls have a mix of abilities that may place them in more than one of the three categories. The firewall remains a vital component in any network security architecture, and today there are several types to choose from. It’s essential that IT professionals identify the type of firewall that best suits the organization’s network security needs.
