DDoS attack

What is DDoS attack?

DDoS is short for Distributed Denial of Service. DDoS is a type of DOS attack where multiple compromised systems, which are often infected with a Trojan, are used to target a single system causing a Denial of Service (DoS) attack. Victims of a DDoS attack consist of both the end targeted system and all systems maliciously used and controlled by the hacker in the distributed attack.

The different between DoS & DDoS?

The difference between a DoS and DDoS attack is quite simple. A DoS attack usually targets a victim at the application layer, with the same intentions of rendering a website unusable. A DoS attack is accomplished by a single user using a single internet connection.

How the attack works?

In a DDoS attack, the incoming traffic flooding the victim originates from many different sources – potentially hundreds of thousands or more. This effectively makes it impossible to stop the attack simply by blocking a single IP address; plus, it is very difficult to distinguish legitimate user traffic from attack traffic when spread across so many points of origin.

How to mitigate the DDoS attack?

There are a few ways to help protect yourself against DDoS attacks.

Keep an eye on the inbound traffic hitting your server. The sooner you see an unusual spike in traffic that looks suspicious, the sooner you can start investigating.
Add filters to your router to drop packets from suspicious sources
Implement rate limiting in the event you are being attacked in order to avoid your server being overwhelmed.
Use a DDoS protection service

OAuth 2.0 framework

What is OAuth 2.0? OAuth 2 is an authorization framework that enables applications to obtain limited access to user accounts on an HTTP service, such as Facebook, GitHub, and DigitalOcean. It works by delegating user authentication to the service that hosts the user account, and authorizing third-party applications to access the user account. OAuth 2 provides authorization flows for web and desktop applications, and mobile devices. This informational guide is geared towards application developers, and provides an overview of OAuth 2 roles, authorization grant types, use cases, and flows. This specification and its extensions are being developed within the IETF OAuth Working Group . How does Social Login work? Social Login is a simple process, with the following steps. The user enters your application and selects the desired social network provider. A login request is send to the social network provider. Once the social network provider confirms the user’s ide...

Cross-site-Request-Forgery-protection-in-web-applications-via-Double-Submit-Cookies-Patterns

Implementation of the Double Submit Cookie Pattern is bit similar to the implementation of the Synchronizer Token Pattern. So before reading this post, It is better to read the last post about the "implementation of Synchronizer Token Pattern". The link for the previous post is as fallows https://hyperstella.blogspot.com/2018/05/cross-site-request-forgery-protection.html Double submit cookie pattern does not store the token value in the server side.It store the token value inside the cookie in the client side. In this post we are going to show the implementation process of Double Submit Cookie Pattern , You can see a sample project (Github) :- https://github.com/MalikDilsh/Cross-site-Request-Forgery-protection-in-web-applications-via-Double-Submit-Cookies-Patterns Step 1: First of all you have to Create a web application similar to the Synchronizer Token Pattern. Because the implementation process of the double submit cookie pattern is mostly equal, ther...

SMSC Gateway Overview An SMS gateway is a platform or service that allows you to send and receive text messages (SMS) using telecommunication networks. It acts as an intermediary between computer systems or applications and mobile network operators, enabling the exchange of SMS messages. Here are some key points about SMS gateways: Functionality: SMS gateways provide the necessary infrastructure and protocols to enable communication between computer systems and mobile networks. They typically offer APIs (Application Programming Interfaces) that developers can use to integrate SMS functionality into their own applications, websites, or systems. Sending SMS: With an SMS gateway, you can send SMS messages programmatically from your own application or system. You need to interact with the gateway's API, providing the recipient's phone number, message content, and other relevant parameters. The gateway then delivers the SMS to the intended recipient through the mobile network. Rece...
