  • NetBSD 8.1 RC1 Released With MDS Mitigations, Option To Turn Off SMT/HT, Driver Updates

    The first and only anticipated release candidate for NetBSD 8.1 is now available for testing.

    The NetBSD 8.1 release candidate adds the necessary mitigations for the Microarchitectural Data Sampling / Zombieload vulnerabilities. With Hyper Threading looking increasingly insecure with these new CPU vulnerabilities, NetBSD has joined other operating systems in offering a new setting to disable HT/SMT support: the smtoff rc.conf option.

  • Outbound Traffic Filtering | Roadmap to Securing Your Infrastructure

    This week, we’re discussing outbound traffic filtering. This is filtering provided at the network edge by a firewall with rules (ACLs) restricting what internal users are allowed to access. Some firewalls have the ability to filter by an application (layer 7 firewalls), but we’re going to concentrate on standard packet-filtering firewalls and their capabilities. There are several reasons for wanting to restrict outbound communications, such as defeating malware, making data exfiltration harder, and the detection of infected hosts.

  • Bluetooth's Complexity Has Become a Security Risk

    Fundamentally, both Bluetooth and BLE open up a channel for two devices to communicate—an extremely useful arrangement, but one that also opens the door for dangerous interactions. Without strong cryptographic authentication checks, malicious third parties can use Bluetooth and BLE to connect to a device they shouldn't have access to, or trick targets into thinking their rogue device is a trusted one.

  • ICE Tops Its Old Record, Spends Another $820,000 On Cellphone-Cracking Tools

    As consecutive heads of the FBI have whined about the general public's increasing ability to keep their devices and personal data secure with encryption, a number of companies have offered tools that make this a moot point. Grayshift -- the manufacturer of phone-cracking tool GrayKey -- has been selling hundreds of thousands of dollars-worth of devices to other federal agencies not so insistent the only solution is backdoored encryption.

    ICE is one of these agencies. It led all federal agencies in phone-cracking expenditures in 2018. It spent $384,000 on these tools last year. It wasn't just ICE. Other agencies like the DEA and [checks notes] the Food and Drug Administration have also purchased these devices. But ICE led the pack, most likely because ICE -- along with DHS counterpart CBP -- are engaging in more suspicionless, warrantless device searches than ever.

  • 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.
