  • Linux servers are getting a welcome security upgrade

    Cybersecurity firm Sophos has acquired Linux security vendor Capsule8 in a bid to extend its protection cover to Linux servers.

    Capsule8 offers a threat detection platform for securing Linux production environments across bare-metal and virtualized servers, as well as containers, whether deployed on-premise or in the cloud.

    Acquired for an unknown sum, Sophos intends to integrate Capsule8’s protection platform into its Adaptive Cybersecurity Ecosystem (ACE) platform.

  • Critical Juniper Bug Allows DoS, RCE Against Carrier Networks

    Telecom providers, including wireless carriers, are at risk of disruption of network service if the bug in SBR Carrier is exploited.

    [...]

    One of these can also be used for RCE, Juniper said. That bug (CVE-2021-0277, with an 8.8 CVSS rating) is an out-of-bounds read vulnerability afflicting Junos OS (versions 12.3, 15.1, 17.3, 17.4, 18.1, 18.2, 18.3, 18.4, 19.1, 19.2, 19.3, 19.4, 20.1, 20.2, 20.3 and 20.4), and Junos OS Evolved (all versions).

    Junos OS and Junos OS Evolved are network operating systems that power Juniper’s enterprise routers and switches. The former runs on FreeBSD, while the latter runs a version of Linux.

    The issue exists in the processing of specially crafted LLDP frames by the Layer 2 Control Protocol Daemon (l2cpd). LLDP is the protocol that network devices use to broadcast their identity, capabilities and neighbors on a local area network (usually over wired Ethernet).

    “Continued receipt and processing of these frames, sent from the local broadcast domain, will repeatedly crash the l2cpd process and sustain the DoS condition,” Juniper said in its advisory, issued Thursday.

    In addition to the patch, this bug has a few workarounds. For instance, users can configure a device to not load the l2cpd daemon. However, if it’s disabled, certain protocols (RSTP, MSTP, VSTP, ERP, xSTP and ERP, among others) won’t work.

  • SonicWall suggests people unplug their end-of-life gateways under 'active attack' by ransomware crims

    SonicWall has warned that its older Secure Mobile Access (SMA) 100 series and Secure Remote Access (SRA) gateways are being attacked in the wild by crooks to spread ransomware – and as some of those devices are end-of-life, don't expect any patches to protect them.

    In an emergency alert on Wednesday, the networking biz said miscreants are "actively targeting" the equipment to, as we understand it, steal credentials from them to compromise networks for "an imminent ransomware campaign."

  • 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.
