Alert Logic Security and Compliance Suite
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.
Threat Stack Intrusion Detection System
This article will review some of the more technical aspects of Threat Stack. Threat Stack is a platform-independent intrusion detection system (IDS) designed to provide users with a unique view into various integrated server security functions. It monitors both Linux and Windows servers as well as Kubernetes or other container-based server infrastructures to observe behaviors and detect malicious, uncommon, and risky activity.

What is SIEM?
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. This necessitates the fact that adding a SIEM is especially warranted at this time.
How to Troubleshoot SMTP Errors: Part 2
In part one of How to Troubleshoot SMTP Errors, we reviewed email status codes, internal reasons for email issues, and troubleshooting steps to address those issues. In part two of this series, we will examine some of the external reasons for email issues.
How to Troubleshoot SMTP Errors: Part 1
What is SMTP?
The Simple Mail Transfer Protocol (SMTP) is a communication protocol used to transmit email between corresponding email servers. Using an email client like Mac Mail, Outlook, Thunderbird, or web clients like Gmail or Windows Live, SMTP can send messages to an email server. Although SMTP was initially designed as an email transport and delivery system, it later encompassed the email submission protocols that are now in use by both the Post Office Protocol (POP) and the Internet Message Access Protocol (IMAP). The above-noted email clients use these protocols to retrieve email from an email server. When this system fails, it provides the means to identify and resolve SMTP errors.
How to Stop Outgoing Email Spam
The most effective method to protect a server from sending spam is to prevent it in the first place. In this article, we provide several techniques to use to keep the server from sending out unwanted spam or junk mail. Typically, unwanted, and unsolicited spam email is usually bulk sent out to an indiscriminate list of recipients. Spam is often used for commercial purposes but can be sent out in massive volume by a botnet or a network of infected computers.
