Alert Logic Security and Compliance Suite
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.
How To Install and Configure Vault
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.
Threat Stack Intrusion Detection System
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.
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 Store Secrets in Kubernetes
What is a Secret?
A Kubernetes Secret is an object that enables us to store and manage sensitive information. A Secret can contain data like SSH keys, OAuth data, or other user authentication information like passwords. It is typically stored within a cluster in a manner native to Kubernetes. Using a Secret object provides more granular control over how highly sensitive data is used. It also lowers the risk of data exposure to unauthorized parties.
What is Blockchain? A Tutorial
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.
How to Locate Open Ports in Linux
What is a Port?
First, let’s define what a port is. According to the IEFT, a port is:
How to Install and Configure Rancher K3s
What is Rancher K3s?
K3s is an official Cloud Native Computing Foundation sandbox project that brings a lightweight, fully compliant Kubernetes distribution designed for lower resource production models like remote locations or on an IoT device. When used in conjunction with Rancher, K3s can easily be managed from within the Rancher orchestration platform.
How to Implement Zero Trust Security in 5 Steps
What is Zero Trust Security?
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.
What are Inodes in Linux?
As you are probably already aware, everything is considered to be a file in Linux. That includes hardware devices, processes, directories, regular files, sockets, links, and so on. Generally, the file system is divided into data blocks and inodes. With that being said, you can think about inodes as a basis of the Linux file system. To explain it more clearly, an Inode is a data structure that stores metadata about every single file on your computer system.
