The internet is, by its nature, a connected place. It’s filled with resources linking to other resources in a glorious spiderweb of information, both delightful and terrifying. Enabling this functionality is the humble URL, which can point you in the right direction or just as easily lead you astray. In this blog post, you’ll learn about a security vulnerability called the open redirect vulnerability and how to protect yourself against it. The open redirect vulnerability allows a malicious actor to craft a special URL that will trick a user into trusting an untrustworthy website. Let’s start by finding out more about this vulnerability. What’s an Open Redirect Vulnerability? Open redirect vulnerabilities happen when a website allows user-generated content to be used as a parameter during a URL redirection. If the user-generated content isn’t validated, an attacker can craft a URL that looks trustworthy but isn’t. This URL will look like it’s on the current domain, but it will in reality point to an external domain under the attacker’s control. Here’s an example. Let’s assume that the MyBank website has a vulnerable redirector that an attacker knows about. MyBank uses the redirect_url parameter to send the user to the page they were trying to access before they were asked to log in. An example of a redirect URL that could be used as a phishing attack. The MyBank website assumes that the redirect_url parameter always points within the site. But an attacker can change this URL so that it redirects to a completely different website named NyBank that’s under the attacker’s control. This means that once the user logs in,...
Google just made it a lot easier to build your very own custom AI system. The technology is limited for now, but it could be the start of something big. Building and optimizing a deep neural network algorithm normally requires a detailed understanding of the underlying math and code, as well as extensive practice tweaking the parameters of algorithms to get things just right. The difficulty of developing AI systems has created a race to recruit talent, and it means that only big companies with deep pockets can usually afford to build their own bespoke AI algorithms. “We need to scale AI out to more people,” Fei-Fei Li, chief scientist at Google Cloud, said ahead of the launch today. Li estimates there are at most a few thousand people worldwide with the expertise needed to build the very best deep-learning models. “But there are an estimated 21 million developers worldwide today,” she says. “We want to reach out to them all, and make AI accessible to these developers.” Cloud computing is one of the keys to making AI more accessible. Google, Amazon, Microsoft, and other companies are rushing to add machine-learning capabilities to their cloud platforms. Google Cloud already offers many such tools, but they use pretrained models. That limits what they can do—for example, programmers will only be able to use the tools to recognize a limited range of objects or scenes that they have already been trained to recognize. A new generation of cloud-based machine-learning tools that can train themselves would make the technology far more versatile and easier to use. Several companies have been testing Google...
Building REST APIs with .NET 5, ASP.NET Core, and PostgreSQL This is old news by now, but I’m still amazed by the fact that nowadays .NET is open source and can run on Linux. I truly believe that this new direction can help the technology realize its true potential, since it’s no longer shackled to Windows-based environments. I’ve personally been outside the .NET game for a good while, but with the milestone release that is .NET 5, I think now is a great time to dive back in. So I thought of taking some time to do just that, really dive in, see what’s new, and get a sense of the general developer experience that the current incarnation of .NET offers. So in this blog post, I’m going to chronicle my experience developing a simple but complete REST API application. Along the way, I’ll touch on the most common problems that one runs into when developing such applications and how are they solved in the .NET world. So think of this piece as a sort of tutorial or overview of the most common framework features when it comes to developing REST APIs. There’s a table of contents at the bottom. First, let’s get familiar with what we’re building. What we’re building The demo application You can find the finished product on my GitHub. The application that we’ll be building throughout this article will address a request from a hypothetical car junker business. Our client wants to automate the process of calculating how much money to offer their customers for their vehicles, given certain information about them. And they want...
Customer relationship management and cloud consulting features provide the entire CRM features with a great experience on a smartphone, tablets, and other Internet Devices. CRM gives assistance with sales, marketing, and customer services which in turn helps in managing the database in real-time. Smartphones have become a necessity in today’s time. It hugely impacts the bottom line and the question that arises is it going boost the sales value or accelerate the cash flow or improve the workflow insight. Why do organizations need cloud-based CRM solutions? Specific stats, state that the number of global internet traffic coming from mobile devices elevated from 0.7 percent in 2009 to 53 percent and the numbers continue to increase continuously. CRM development services would allow users to access the data no matter where they are which allows them to function while they are on the go. Let us look at the benefits of Mobile CRM What are the benefits of Mobile CRM? Mobile CRM software provides all functionalities of a system hosted on a computer or a laptop but it also adds an off the go access through cloud-based adds the benefit of on-the-go access through CRM solutions. Benefits to employees: With the upcoming work sphere in mobile devices, researchers are claiming that it increases 240 hours of work annually with mobile devices. With remote access to the features, they are providing it to be more productive. Fields agents would largely need access to schedule and work even when they are not in the office. It helps in providing a collaborative work environment irrespective of compatibility issues. Benefits to the customers: Customers benefit...
Definition of Cyber Security as a Discipline: It is a discipline that deals with the security of electronic gadgets connected through the internet like networks, computers, mobile devices, and software within those systems from any kind of malicious software. It is also considered Electronic Information Security. The professional of this discipline is protecting all the gadgets safely connected to the internet. Cyber Security Experts are supposed to look for any weakness in the system, software, or electronic device from outside. They protect the overall system from intrusion through the internet. You learn various methods, techniques or develop strategies based on the solid knowledge ground to protect the system. The professional from this discipline also provides inputs in the development of software, to make the software protected from possible threats. Expert is constantly monitoring the overall system for any possible intruders attack. The development of new protocols and security systems based on the threat intensity and level is also the task of professionals. The main topics of this discipline may be mobile device protection from online viruses, warms, or hacking threats, developing and maintaining the privacy of the individual users, counteracting against any data breach, ensuring safe computing, online scams, etc. Brief History of the Discipline: An Army General SUN Tzu Wu in China, about 20 years ago has written in his book “The Art of War” about vulnerabilities. His book is about series of engagements with the enemy. He says, “One who knows the enemy and knows himself will not be in danger in 100 battles, One who does not know the enemy but knows himself, will sometimes win...
