In this article, In this article, Toptal engineer Ilya Sanosyan provides a practical guide to maximizing the value we get from our logs.
Authentication is one of the most important parts of any web application. For decades, cookies and server-based authentication was the easiest solution. However, handling authentication in modern Mobile and Single Page Applications can be tricky and demand a better approach. One of the best known solutions to authentication problems for APIs is the JSON Web Token (JWT).
Linux namespaces make it possible to run a whole range of applications on a single real machine and ensure no two of them can interfere with each other, without having to resort to using virtual machines. In a single-user computer, a single system environment may be fine. But on a server, where you may want to run multiple services, it is essential to security and stability that the services are as isolated from each other as possible.
For all too many companies, it's not until after a breach has occurred that security becomes a priority. An effective approach to IT security must, by definition, be proactive and defensive. This article focuses on avoiding 10 common and significant web-related IT security pitfalls.
A potentially critical problem, nicknamed "Heartbleed", has surfaced in the widely-used OpenSSL cryptographic library. The vulnerability is particularly dangerous in that potentially critical data can be leaked and the attack leaves no trace. As a user, chances are that sites you frequent regularly are affected and your data may have been compromised. As a developer or sys admin, sites or servers you're responsible for are likely to have been affected. Here are the key facts you need to know about this dangerous bug and how to mitigate your vulnerability.
