![]() The targeted server sends a response back to the computer in the same format and along the same route. As the computer sends a request across the internet, it takes the form of a packet of data that travels through the network until it reaches its destination. One of the most important aspects of a firewall is the filtering option. There are a couple of functions used by the firewall to ensure your servers’ safety, and we will briefly go through them. A firewall blocks unauthorized requests and allows passage only to designated traffic. Without a firewall, any request will pass through to vulnerable systems, making it possible for malicious actors to access your computer for their own gain. #UTM DEVICE SOFTWARE#In other words, firewall software is installed with the intention of scanning every incoming and outgoing packet of data, checking for malicious or inappropriate content, and then allowing or denying the packet of data entry into the system. The firewall is a piece of software that stands between your computer or network and the Internet. That is why the firewall is essential because it acts as the doorkeeper. A firewall paired with an anti-malware suite can save your business from cyberattacks and virus infection that could lead to significant revenue loss if not dealt with in time.Ĭonnecting your computer to the world-wide-web is like leaving your front door open and allowing outsiders to get in. If your firewall is maintained correctly, it will protect your servers from external threats and deal with more subtle problems by alerting you and intercepting ongoing data. You can view your firewall as the gatekeeper between the organization’s servers and the outside world. The Purpose Of A FirewallĪ firewall is one of the most vital pieces of defense your business has against digital threats. We are here to strip down the precise differences between two terms that are often used interchangeable next-generation firewall and unified threat management-and help you determine which option will offer better protection for your sensitive user information and critical private data. Therefore, choosing between next-generation firewall or unified threat management could help understand what each security solution offers. However, many are puzzled by the solution they found out there on the market, and it makes it difficult to decide which solution is best suited for your needs. With the increasing need for more secure and reliable systems, many companies seek high-end solutions to protect their data and avoid downtime due to cyber threats. However, another multipurpose option is available: a unified threat management (UTM) appliance. ![]() It’s now standard to employ some firewall type on every system, most commonly a next-generation firewall (NGFW). While UTMs are targeted at the midsize enterprise that doesn’t generally host Web applications, NGFWs will find their home in large enterprises supporting Web 2.0 applications.Data security remains the most critical cybersecurity issue on the map today. UTMs and NGFWs will peacefully coexist in the marketplace for quite some time, because they serve very different markets. Like the introduction of stateful inspection, NGFWs bring additional context to the firewall’s decision-making process by providing it with the capability of understanding the details of the Web application traffic passing through it, taking action to block traffic that might exploit Web application vulnerabilities. A next-gen firewall is designed to combine the functionality of a firewall and an IPS, while adding detailed application awareness into the mix. I’d actually consider them an advancement from stateful inspection technology, rather than comparing them to UTM devices. ![]() Next-generation firewalls (NGFW) represent the next major step in the development of firewall technology. While this approach is not often appropriate for a large enterprise, a UTM device can be a very effective product for smaller or midsize enterprises seeking to limit security expenditures. You’ll find that these products often consolidate firewall, intrusion prevention, content filtering, antivirus and other security functionality into a single box. ![]() You’re correct in pointing out that unified threat management (UTM) products are basically stateful inspection firewalls with some additional security functionality. ![]() Instead of simply making independent decisions each time it encountered a packet, the firewall was now context-aware, able to make decisions based upon the information it had gathered about a connection. Stateful inspection added intelligence and memory to the firewall. When stateful inspection firewalls first came on the scene in the 1990s, they revolutionized network security by allowing perimeter protection to move beyond the simple packet-by-packet filtering process used up until that point.
