One of the best ways of keeping intruders away is to createbarriers or a wall. The same principle applies online. The technology hasmade it possible to filter network traffic through multiple layers, all of which are intended to prevent hackers and viruses. These cyber attacks can be found at the application, network, and transport level as well as at the data link level. The next generation firewall is more efficient Sophos Colombia.
Traditional firewall security vs. New generation firewall
The traditional firewall was used to filter trafficaccording to ports and protocols. You could block or allow all traffic onport 80 (HTTP traffic) or port 443 (HTTPS traffic). This is known as an "all-or nothing" approach.
Newer firewall technology filters or manages traffic basedon the type of traffic that is traversing these ports. Port 80 can only beopened for HTTP traffic, or for specific sites or applications that you want to allow. This could be interpreted as combining the firewall and quality-of-service (QoS), functionalities into one solution.
Although the application-aware firewalls can be callednext-generation firewalls (NGFW), they were originally part of unified threatmanagement solutions (UTM). However, the UTM is referred to the products, which face deficiency in true application-awareness and are directed towards the SMB market. Threat management solutions can offer additional functionality (antivirus, spamm or intrusion prevention system (IPS) over traditional firewalls, providing excellent cyber security.
NGFWs allow fine-tuning traffic features to controlbandwidth and security. Because they are more intelligent, they can catchmore malicious activity. They also have the ability to lend QoS functions, which is another reason they are preferred over traditional firewalls. This means that applications with higher priority receive more bandwidth. Not only is there a need for better cyber security but also for NGFWs due to the increased cloud services and providers of outsourced software as a Service (SaaS).
Common features for NGFWs:
Common firewall characteristics: Protocol inspection,network address translations (NAT), VPN are just a few of the common functions.
Application identification & filtering: This is thekey feature that makes it easier to identify specific applications and filtertheir traffic. It prevents malicious activities and applications from using non-standard ports to bypass the firewall.
