How Can You Ensure Security on a Server?

It is important to secure your server to prevent data loss or security compromises. Because security is such a challenging subject for many, it often goes unheeded. Many are caught unaware when an issue arises. By following these best practices, you can significantly lower your risk of being compromised by a malicious actor.

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.

What is Vault?

Vault protects and secures access to multiple types of confidential data. It stores and manages sensitive password information, API keys, and access tokens that exist in a low trust environment and generates dynamic access to authenticate users to ensure they have authorized ingress and availability to a file, location, service, or application.

Introduction

This article will review some of the more technical aspects of F5 Distributed Cloud AIP. F5 Distributed Cloud AIP 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.

Introduction

In this article, we provide updated information concerning the ongoing threat posed by the malware directed at Microsoft Exchange Servers noted in CVE-2021-26855. We also furnish the steps needed to update and secure your Microsoft Exchange Server. In a recent post, the Cybersecurity & Infrastructure Security Agency posted a priority security advisory regarding the recent Microsoft Exchange Server vulnerability. They state:

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.

The idea of blockchain itself may sound complicated, but the premise is simple. Blockchain is a zero-trust, fully decentralized peer-to-peer data storage system that spreads verified information across participants in the chain, referred to as nodes. Blockchain stores this information in blocks that are chained together. As new data arrives, it is recorded into a block. Once a block has been filled with information, it is linked to the previous block. This process allows the data to be bound together in sequential and chronological order. 

What is a Port? 

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

What is 2FA

Two-Factor Authentication (or 2FA as it often referred to) is an extra layer of security that is used to provide users an additional level of protection when securing access to an account. 

Zero Trust security is the concept, methodology, and threat model that assumes no user, system, or service operating within a secured internal environment should be automatically trusted. It put forward that every interaction must be verified when trying to connect to a system before being granted access. This concept uses micro-segmentation, and granular edge controls based on user rights, application access levels, service usage, and relation to the location to determine whether to trust a user, machine, or application seeking to access a specific part of an organization.
