1. What is a next-generation firewall? From the earliest packet-filtering firewalls to the present, the firewall has experienced five generations of evolution, each era of evolution to the firewall to inject new technology and vitality. With the sharp increase in network activities and growing complexity, network attacks are also showing a trend of diversification and compounding. The performance of traditional firewalls and UTMs in dealing with new threats to the network is becoming increasingly stretched and unable to meet the security needs of enterprise users.

2. The difference between traditional firewalls and UTMs; from the previous understanding, in order to comply with the new security situation, the next-generation firewall must be able to target applications, users, terminals, and content for high-precision control, with an integrated engine and realize the intelligent data linkage of multiple security modules, scalable external security intelligence and provide high processing performance, to help users to safely carry out their business and simplify the users' network security architecture. network security architecture. So what are the differences between next-generation firewalls and traditional firewalls and UTMs?

3. What are the weaknesses of traditional firewalls? Traditional firewalls have packet filtering, Network Address Translation (NAT), protocol state checking, and VPN functionality. Comparatively speaking, the detection of next-generation firewalls is much more refined. Not only that, but the inherent flaws of traditional firewalls that use ports and IP protocols for control are clearly outdated, and threats that utilize botnets as a method of transmission are largely undetectable. At the same time, due to the adoption of service-based architecture and the popularity of Web 2.0 usage, more communication is conducted through only a few ports and using a limited number of protocols, which means that the relevance and efficiency of port/protocol-based security policies are getting lower and lower. Deep packet inspection intrusion prevention systems (IPS) can check operating systems against known attacks and miss deployed patches, but are not effective in identifying and preventing application misuse, let alone protecting specific features of an application.
