A next-generation firewall (NGFW) is a part of the third generation of firewall technology, combining a conventional firewall with other network device filtering functions, such as an application firewall using in-line deep packet inspection (DPI) and an intrusion prevention system (IPS).
An application firewall is a form of firewall that controls input/output or system calls of an application or service. It operates by monitoring and blocking communications based on a configured policy, generally with predefined rule sets to choose from.
Intrusion prevention systems (IPS), also known as intrusion detection and prevention systems (IDPS), are network security appliances that monitor network or system activities for malicious activity. The main functions of intrusion prevention systems are to identify malicious activity, log information about this activity, report it and attempt ...
Deep packet inspection (DPI) is a type of data processing that inspects in detail the data being sent over a computer network, and may take actions such as alerting, blocking, re-routing, or logging it accordingly.
Free and open-source software portal; ModSecurity, sometimes called Modsec, is an open-source web application firewall (WAF). Originally designed as a module for the Apache HTTP Server, it has evolved to provide an array of Hypertext Transfer Protocol request and response filtering capabilities along with other security features across a number of different platforms including Apache HTTP ...
Attacks which are spread out across a long period of time or a large number of source IPs, such as nmap's slow scan, can be difficult to pick out of the background of benign traffic. An online password cracker which tests one password for each user every day will look nearly identical to a normal user who mistyped their password.
