  • Scanning for secrets

    Projects, even of the open-source variety, sometimes have secrets that need to be maintained. They can range from things like signing keys, which are (or should be) securely stored away from the project's code, to credentials and tokens for access to various web-based services, such as cloud-hosting services or the Python Package Index (PyPI). These credentials are sometimes needed by instances of the running code, and some others benefit from being stored "near" the code, but these types of credentials are not meant to be distributed outside of the project. They can sometimes mistakenly be added to a public repository, however, which is a slip that attackers are most definitely on the lookout for. The big repository-hosting services like GitHub and GitLab are well-placed to scan for these kinds of secrets being committed to project repositories—and they do.

    Source-code repositories represent something of an attractive nuisance for storing this kind of information; project developers need the information close to hand and, obviously, the Git repository qualifies. But there are a few problems with that, of course. Those secrets are only meant to be used by the project itself, so publicizing them may violate the terms of service for a web service (e.g. Twitter or Google Maps) or, far worse, allow using the project's cloud infrastructure to mine cryptocurrency or allow anyone to publish code as if it came from the project itself. Also, once secrets get committed and pushed to the public repository, they become part of the immutable history of the repository. Undoing that is difficult and doesn't actually put the toothpaste back in the tube; anyone who cloned or pulled from the repository before it gets scrubbed still has the secret information.

    Once a project recognizes that it has inadvertently released a secret via its source-code repository, it needs to have the issuer revoke the credential and, presumably issue a new one. But there may be a lengthy window of time before the mistake is noticed; even if it is noticed quickly, it may take some time to get the issuer to revoke the secret. All of that is best avoided, if possible.

  • Resurrecting DWF

    Five years ago, we looked at an effort to assist in the assignment of Common Vulnerabilities and Exposures (CVE) IDs, especially for open-source projects. Developers in the free-software world have often found it difficult to obtain CVE IDs for the vulnerabilities that they find. The Distributed Weakness Filing (DWF) project was meant to reduce the friction in the CVE-assignment process, but it never really got off the ground. In a blog post, Josh Bressers said that DWF was hampered by trying to follow the rules for CVEs. That has led to a plan to restart DWF, but this time without the "yoke of legacy CVE".

  • Vulnerability analysis for Golang applications with Red Hat CodeReady Dependency Analytics

    Red Hat CodeReady Dependency Analytics, powered by Snyk Intel Vulnerability database, helps developers find, identify, and fix security vulnerabilities in their code. In the latest 0.3.2 release, we focused on supporting vulnerability analysis for Golang application dependencies, providing easier access to vulnerability details uniquely known to Snyk, and other user experience improvements.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
