Introduction

Intrusion detection systems (IDSs) are an ever-present requirement in a cybersecurity infrastructure to ensure a server or internal network is protected. An intrusion detection system is either a hardware device or software program that actively monitors a server or group of servers for network policy violations or malicious activity. Any suspicious activity, attempted attack, or policy violation is reported and logged to a centrally located security information and event management (SIEM) system database, or directly to a security administrator for further review. This article explores Liquid Web’s intrusion detection product called Alert Logic Security and Compliance Suite.

SIEM 2

Security Information and Event Management (or SIEM) is a subset of the computer security field, where applications and services join forces with security event management and security information management. When united, these disciplines provide significantly improved real-time statistical data and threat analysis of alerts generated by the related applications. The 2021 Internet Security Threat Report from Sophos denotes that are not only the number of attacks on the rise but also the diverse nature of methodologies and vectors of incursions used.
