问题 is there a way that you can specify a separate encryption and validation key. Currently, there is just one master key that does both validation and encryption. However, we have several applications in a web farm and only one of them run on ASP.NET CORE and this is hosted on IIS. The rest of the application (Running on ASP.NET *Not core) use the same machine key. The machine key has, of course, the decryption and validation keys and all the other applications use this same machine key to

问题 I read document like this TrustZone Security Whitepaper. It describles that all resources like CPU, memory and others are divided by Secure World and Normal World . Programs in Normal World can not access resources in Secure World. You must call a special instrustion SMC to switch from Normal to Secure world (go through Monitor Mode). As I know, modern OS like Linux provides Kernel Mode and User Mode . User processes can not access resources located in kernel space, but invoke system calls. I

问题 I'm building a website using Node and Express JS and would like to throttle invalid login attempts. Both to prevent online cracking and to reduce unnecessary database calls. What are some ways in which I can implement this? 回答1: Maybe something like this might help you get started. var failures = {}; function tryToLogin() { var f = failures[remoteIp]; if (f && Date.now() < f.nextTry) { // Throttled. Can't try yet. return res.error(); } // Otherwise do login ... } function onLoginFail() { var

问题 After setting up eslint-plugin-security, I went on to attempt to address nearly 400 uses of square brackets in our javascript codebase (flagged by the rule security/detect-object-injection). Although this plugin could be a lot more intelligent, any uses of square brackets could possibly be an opportunity for a malicious agent to inject their own code. To understand how, and to understand the whole context of my question, you need to read this documentation: https://github.com/nodesecurity

问题 I've seen plenty of ink spilled by now about how Docker is not sufficiently isolated to allow arbitrary containers to be run in a multi-tenant environment, and that makes sense. "If it's root in Docker, consider it root in the host machine." What about non-root though? If I want to take some untrusted code and run it in a container, can it be done safely so long as the container is running as a non-root non-sudo user? What are the potential security pitfalls of doing something like that? I'm
