CSP is one of the OWASP’s top 10 secure headers and often recommended by security experts or tools to implement it. There are many options to build the policy to enforce how you want to expose your web resources.

By the end of this tutorial, you will be able to understand the YAML and its syntax....

The date Magento set for the End of Life (EOL) of its version 1 was June 2020, which means it is already a fait accompli. That doesn’t mean that all stores running on Magento 1 stopped working. Still, the results of this EOL could be equally damaging: the developers stopped supporting and updating the software, and therefore, it becomes more vulnerable to threats of all kinds every minute. At the time of writing, 98,581 websites are using Magento 1 as per SimilarTech....

What started as a venture idea from Jeff Bezos’s garage is now a billion-dollar revenue-making company and the standalone leader of ebooks and audiobooks in the market. The Kindle platform allows you to buy or rent books and lets you publish and sell them, thereby exercising the space to build a book-exclusive eCommerce platform that is just a click away for its readers. On the other hand, Audible is the most preferred platform for people who are always on the go, as you can plug in your earbuds/earphones and have the audiobook play in the background while you go about your commute....

Monica makes keeping track of all this MUCH easier. It is an open-source personal CRM. Let’s take a look at getting an instance of Monica’s personal CRM set up in Docker on Linode....

Why? 403 (forbidden) HTTP status code gives a clue about a correct path, and you don’t have permission to access it. This confirms file/folder exists and it’s restricted. Thus, 403 allows the hacker to know more about your file system structure and room for security vulnerabilities. It’s a good idea to redirect 403 return code to 404 (not found), so there is no room for a guess. This is often asked to implement in the payment industry or transactional application production system....

In default NGINX configuration, the Server header banner is ON which exposes what version of Nginx you are using. This is considered as information leakage vulnerability. If you are working on auditing or fixing a security issue, then you will be asked to get rid of a version as part of hardening & security. Implementation Go to nginx/conf folder Take a backup of a configuration file Add the following in nginx....

Today we are going to discuss what this challenge is and explore exactly how we can scale and optimize CI/CD. So, follow along! Nowadays, application development is usually done in teams consisting of several developers. Each person or team has its role in the project by advancing on their dedicated part. We then find ourselves at the end of the project with several pieces of code to compile. Depending on everyone’s working methods, much time can be wasted managing this integration....

The growth of multimedia content, the increasing use of mobile devices, and the demand for cloud computing have all contributed to the need for more flexible and efficient networking architectures. As these trends have led to unpredictable traffic patterns and sudden increases in demand for particular resources, traditional networking architectures have struggled to keep up. There was a need for an alternative strategy because scaling network infrastructure to handle these fluctuations can be very costly and complicated....

As of writing, asynchronous is no more just a buzzword in the Python community. With the release of its asyncio library in 3.5 version, Python acknowledged the impact of Node.js on web development and introduce two new keywords into the language — async and await. This was a very big deal because the Python language is extremely wary of expanding the core syntax unless there’s a pressing need, which only indicates how fundamentally important the Python developers considered the asynchronous capabilities....

Crypto wallets help you interact with blockchain technology. They support buying, selling, storing, mining, staking, and everything that’s possible with the specific blockchain they are meant for.
