JavaScript is the most commonly-used programing language, according to the most recent StackOverflow developer survey. While JavaScript offers great flexibility and ease of use, it also introduces security risks that can be exploited by attackers. In this blog, we will explore vulnerabilities in JavaScript, best practices to secure your code, and tools to prevent attacks.
Zeek® is the world’s most widely used network security monitoring platform and is the foundation for Corelight network evidence. In this blog I share how to write a Zeek package in TypeScript with a new capability called ZeekJS that was released as part of Zeek 6.0.
According to Snyk's 2022 State of Open Source Security report, the average JavaScript project has 49 vulnerabilities, including common ones like unsafe dependencies, cross-site scripting (XSS), weak input validation, and cross-site request forgery (CSRF). And given JavaScript's widespread use, robust security measures are increasingly important to safeguard your applications from cyberattacks.
The healthcare industry has rapidly embraced digital technologies to enhance patient care, streamline operations, and improve communication. However, this digital transformation brings with it a significant challenge: protecting patient data. One often overlooked risk comes from tracking pixels, which can lead to (accidental) data leakage and privacy breaches.
In the ever-evolving landscape of cybersecurity, staying ahead of threats and ensuring the safety of sensitive customer data is paramount. For organizations that handle payment card information, complying with industry standards like PCI DSS (Payment Card Industry Data Security Standard) is not only a best practice, but a compliance requirement that can result in hefty fines upwards of $100,000 a month.
JavaScript runtimes help you build advanced, server-driven JavaScript projects that aren't dependent on the user's browser to run. There are several choices of runtimes available, with the supremacy of the old stalwart Node.js being challenged by Deno and Bun. Deno is the latest project produced by the same developer who originally created Node.js, Ryan Dahl, back in 2009.
The Document Object Model (DOM) acts as an interface between HTML and JavaScript, bridging the gap between static content and dynamic interactivity. This function makes the DOM indispensable for modern web developers. However, the DOM has a pitfall — DOM clobbering. DOM clobbering occurs when HTML elements conflict with global JavaScript variables or functions, which can lead to unexpected behavior and a potential security loophole in your web application.
SBOM is the acronym for Software Bill of Materials, which is a list of all the open source npm packages that are part of your project. But it’s not only limited to open source or software packages, and can include operating system libraries, microservices inventory and more.
