An intrusion detection system is a device or software application that monitors a network or systems for malicious activity or policy violations. Any intrusion activity or violation is typically reported either to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system combines outputs from multiple sources and uses alarm filtering techniques to distinguish malicious activity from false alarms.

In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet.
In network security, evasion is bypassing an information security defense in order to deliver an exploit, attack, or other form of malware to a target network or system, without detection. Evasions are typically used to counter network-based intrusion detection and prevention systems but can also be used to by-pass firewalls and defeat malware analysis. A further target of evasions can be to crash a network security defense, rendering it in-effective to subsequent targeted attacks.

Forcepoint is an American multinational corporation software company headquartered in Austin, Texas, that develops computer security software and data protection, cloud access security broker, firewall and cross-domain solutions.
Unified threat management (UTM) is an approach to information security where a single hardware or software installation provides multiple security functions. This contrasts with the traditional method of having point solutions for each security function. UTM simplifies information-security management by providing a single management and reporting point for the security administrator rather than managing multiple products from different vendors. UTM appliances have been gaining popularity since 2009, partly because the all-in-one approach simplifies installation, configuration and maintenance. Such a setup saves time, money and people when compared to the management of multiple security systems. Instead of having several single-function appliances, all needing individual familiarity, attention and support, network administrators can centrally administer their security defenses from one computer. Some of the prominent UTM brands are Cisco, Fortinet, Sophos, Netgear, Huawei, Wi-Jungle, SonicWall and Check Point. UTMs are now typically called next-generation firewalls.
