What is Transport Layer Security (TLS)?

Transport layer security (TLS) is another security protocol designed for privacy and data security among Internet communications. It encrypts communication between web apps and servers and is also used to encrypt email, messaging, and voice over IP (VoIP).

What is Webmin?

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.

Email. We all use it, and we all have spam issues from time to time. Whether you use Gmail, Outlook, Hotmail, Apple Mail, or another type of webmail software, spam is an annoyance that robs us of precious time that should be made available for more worthwhile pursuits. This article will demonstrate multiple methods for filtering out a significant portion of bothersome and inconvenient spam from our inbox.

Introduction

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.

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.

Introduction

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.

What is a Port? 

First, let’s define what a port is. According to the IEFT, a port is: 

What is Thunderbird?

Thunderbird is one of the most widely used open-source email clients in the world. Mozilla originally developed the software in 2004, but the project waned in 2014/15, and Mozilla stated that they would only deliver security and maintenance updates in the future. Until recently, the community maintained the software when a Mozilla Foundation subsidiary, MZLA Technologies Corporation, took over. Today, the improvements in security and stability are very much appreciated, and since version 78, Thunderbird has built-in OpenPGP encryption technology enabled by default. Earlier versions used the available PGP technology, but it needed to be installed as a supplemental plugin.
