Cross Site Scripting (XSS) - Reflected Cross Site Scripting

 





If login is failed, the application generates an HTML response with user-entered data. But the page generation is performed without data encoding, thereby exposing the application to an XSS vulnerability.


If the server response is based on user-entered data, the parameters have to be encoded to make HTML markup. For this, the Tag-helpers provided by the RazorPages are used to create a prepared in advance input form with encoded user data. So, HTML injections will be unavailable, thereby eliminating the Reflected XSS vulnerability.

Scalability and high availability

 Scalability and high availability are critical principles in designing modern software architectures, particularly in distributed systems and cloud-based applications. Understanding these concepts helps ensure that applications can handle increasing loads and remain operational with minimal downtime. Below is a detailed explanation of both principles. Scalability Scalability refers to the ability of a system to handle increased loads without sacrificing performance or availability. It involves adding resources to a system to accommodate growing user demands, data volumes, or transaction rates. There are two primary types of scalability: 1. Vertical Scalability (Scale-Up) Definition : This involves adding more resources (CPU, memory, storage) to an existing server or node. Use Case : Ideal for applications that are not designed for distributed environments or require high levels of computational power. For example, upgrading a database server with more RAM to handle more queries. ...

Microservices and Service-Oriented Architecture

  Microservices Architecture and Service-Oriented Architecture (SOA) , along with their similarities, differences, and typical use cases. Microservices Architecture Microservices is an architectural style where applications are composed of small, independent services that communicate over a network. Each service is typically designed around a specific business function and operates as an isolated, self-contained unit. Here are some key characteristics: Independently Deployable : Each service can be developed, deployed, and scaled independently of others. Single Responsibility : Services are organized around business capabilities, such as “Order Processing” or “User Authentication.” Resilience : Each microservice operates independently, making the system more resilient since failures in one service do not necessarily impact others. Polyglot Persistence and Programming : Microservices allow for diverse technologies, frameworks, and databases across services, optimizing each service...

Version control and Continuous Integration/Continuous Deployment (CI/CD)

 Version control and Continuous Integration/Continuous Deployment (CI/CD) are fundamental practices in modern software development that enhance collaboration, maintainability, and quality of software projects. Below, we’ll explore each concept, including their principles, benefits, and key practices. Version Control Version Control is a system that records changes to files or sets of files over time, allowing developers to track and manage changes to their codebase. It facilitates collaboration among team members and provides a history of changes, making it easier to revert to previous versions if needed. Key Principles of Version Control Track Changes : Every change made to the codebase is recorded, allowing developers to see who made changes, what changes were made, and when. Branching and Merging : Developers can create branches to work on features or fixes in isolation without affecting the main codebase (usually referred to as the main or master branch). Once the work is co...
