Intrusion detection and prevention systems are the most reliable form of securing APT incidences and the overall security of the information infrastructure. This is because, unlike susceptibility and management systems and IT infrastructure support, they have the capacity to detect occurrences of APT and subsequently prevent damage to the computer systems. Firewalls are supposed to block illicit impound traffic, but in most instances, they do not succeed. Intrusion detection and prevention systems have the capability to detect and catch threats missed by the firewalls. Susceptibility management systems are used to identify, remediate and mitigate vulnerabilities in computer networks but ...
