A next generation firewall (NGFW) performs deep packet inspection to check the contents of the data flowing through the firewall. Unlike more basic firewalls that only check the header of data packets, NGFWs examine and evaluate the payload data within the packet. Who Needs a Next-Gen Firewall?
The network firewall is the first line of defense for traffic that passes in and out of a network. The firewall examines traffic to ensure it meets the security requirements set by the organization, and unauthorized access attempts are blocked. Firewall protection has come a long way in recent years. Next-generation firewalls.

The botnet was first discovered by Fortinet in March, the DDoS botnet targeted several routers and web servers by exploiting known vulnerabilities. The researchers attribute the botnet to the cybercrime group Keksec which focuses on DDoS-based extortion. Experts pointed out that the malware is being actively developed.
Distributed Denial of Service (DDoS) DDoS attacks have surged dramatically over the last few years, and will likely continue to pose a threat considering both how easy they are to execute, and how fast botnets (vast networks of compromised devices) are scaling. To stay ahead, organizations must turn to artificial intelligence.
