DevOps stands for development and operations, a combination of practices and tools that improve companies’ ability to rapidly build, update and deliver applications. It is a software development methodology that combines a software framework and IT functions to improve the speed and reliability of software delivery. It is a culture and set of processes that focus on collaboration, automation and integration throughout the software development lifecycle, from development and testing to deployment and maintenance.

Terraform Introduction

Terraform is an open source tool used to manage cloud infrastructure resources. It allows you to create, change, and destroy resources on cloud infrastructure like AWS, GCP, Azure, and DigitalOcean. It is often used by developers who need to work on multiple projects simultaneously. Read more about the basics, along with examples of real-world applications. Terraform Introduction Terraform is an open-source infrastructure as code (IaC) software tool created by HashiCorp. It allows users to define and provision data center infrastructure using a declarative configuration language.

List of basic python commands and data types: Assignments and Expressions In Python, an assignment is a statement that binds a value to a variable. An expression is a combination of values, variables, and operators that evaluates to a single value. Assignments An assignment statement has the following syntax: 1 variable = expression The left-hand side of the assignment operator (=) is a variable name, and the right-hand side is an expression that evaluates to a value.

Security Hardening: Security hardening is the process of configuring and implementing measures to reduce the vulnerability of a system, network, or application to potential attacks or breaches. This involves removing or disabling unnecessary features, patching known vulnerabilities, and configuring settings to minimize exposure to threats. OS Hardening: The process of securing an operating system by reducing its attack surface, disabling unnecessary services and features, and configuring it to follow best practices for security.

Network Protocols A set of rules for devices to communicate over a network, describing data delivery and structure. Serve as instructions for receiving devices to process data. Categories of Network Protocols Communication Protocols: govern data exchange and transmission between devices. Management Protocols: monitor and manage network activity. Security Protocols: ensure secure data transmission using encryption. Communication Protocols TCP (Transmission Control Protocol): establishes connections and streams data between devices. UDP (User Datagram Protocol): connectionless protocol for fast data transmission.

Understanding OCSP: Enhancing Digital Certificate Security

Chay published on  included in Tech Articles
Understanding OCSP: Enhancing Digital Certificate Security The Online Certificate Status Protocol (OCSP) is a critical mechanism for maintaining the security of servers and network resources by checking the status of digital certificates in real-time. OCSP is an alternative to the older Certificate Revocation List (CRL) method, which required frequent updates to ensure client-side accuracy. How OCSP Works OCSP addresses the main limitation of CRLs by providing real-time certificate status checks. When a user attempts to access a server, OCSP sends a request for the certificate status.

Understanding Certificate Revocation Lists (CRLs)

Chay published on  included in Tech Articles
What is a Certificate Revocation List (CRL)? A Certificate Revocation List (CRL) is a critical security feature that maintains the trustworthiness of digital communications. Managed by a Certificate Authority (CA), a CRL is a directory of digital certificates that have been invalidated before their scheduled expiration dates. This list helps various endpoints, such as web browsers, determine whether a certificate should be trusted. CRLs are essentially blocklists of certificates that should no longer be trusted.

Hub Switch Router & Modem Hub: A basic networking device that connects multiple Ethernet devices, making them act as a single network segment. It broadcasts data to all connected devices, which can lead to collisions and inefficiencies. Switch: An advanced version of a hub that connects devices on a local area network (LAN). Unlike a hub, a switch intelligently forwards data only to the specific device that needs it, reducing collisions and improving network efficiency.
