OAuth OAuth is an open standard for access delegation, allowing users to grant third-party applications access to their information without sharing their credentials (typically username and password). Instead, OAuth provides tokens that applications can use to access resources on behalf of the user. OpenID Connect OpenID Connect (OIDC) is a simple identity layer built on

Introduction to Single Page Applications (SPAs) Security Single Page Applications (SPAs) have grown in popularity because they often provide a smoother user experience compared to traditional multi-page web applications. Unlike multi-page applications that reload the entire page from the server whenever a user interacts with the app, SPAs dynamically rewrite the current page in response

Understanding Denial of Service (DoS) Attacks Before diving into mitigation strategies, it is essential to understand what Denial of Service (DoS) attacks entail. A DoS attack aims to make a network service or application unavailable to intended users by overwhelming it with fake traffic or requests. In distributed denial-of-service (DDoS) attacks, this is done using

Vulnerability scanning is an integral part of maintaining the security of web applications. Automating this process ensures that threats are identified and addressed promptly. The following sections outline steps for automating vulnerability scanning. Establishing a Baseline Before automating vulnerability scanning, you must establish a baseline to understand your web application’s current security posture. Inventory Web

Creating a secure application development lifecycle involves several important steps. Each step should be meticulously planned and executed to ensure that security considerations are integrated throughout the entire process. Here’s a detailed guide on how you can create and manage a secure application development lifecycle: 1. Establish Security Requirements and Policies Identify and understand the

Securing data is a critical aspect of modern applications. This involves protecting data not only when it’s being transmitted over the network (in transit) but also when it’s stored (at rest). Different strategies and technologies apply to these two states. Below are detailed methods to secure data both in transit and at rest within applications.

Conducting penetration testing on your applications is an essential activity to identify and fix security vulnerabilities before a malicious actor can exploit them. Below is a detailed guide on how to conduct penetration testing on your applications effectively. Planning and Preparation Scope Definition: Determine the boundaries of the test—establish which applications and systems will be

When developing an application, managing and securing its dependencies is crucial. Dependencies, which are external code libraries or packages that an application relies on to function, can contain vulnerabilities that might be exploited by attackers. To minimize risk, it’s important to follow a set of best practices. Inventory Your Dependencies Catalogue Every Dependency: Keep an

Brute force attacks involve an attacker submitting many passwords or passphrases with the hope of eventually guessing a user’s credentials correctly. Implementing rate limiting is one of the effective ways to mitigate such attacks. Below is a detailed guide on how to implement rate limiting to protect your system against brute force attacks. Understanding Rate

File uploads are a common feature on many websites, allowing users to share images, documents, and other kinds of files. However, this functionality can be a significant vulnerability if not implemented securely. Attackers can exploit file upload features to upload malicious files, which may lead to unauthorized access, data breaches, or the distribution of malware.
