A practical example of connecting a Ceph-based storage to a Kubernetes cluster

Posted on

Container Storage Interface (CSI) is a unified interface that facilitates interaction between Kubernetes and storage systems. We’ve previously provided a brief overview of it, and today we will take a closer look at the integration of CSI and Ceph: demonstrating how to connect a Ceph storage system to a Kubernetes cluster. The article contains real, albeit slightly simplified, examples for ease of understanding. Instructions for installing and configuring Ceph and Kubernetes clusters […]

Features of Mobile Device Firmware Updates

Posted on

Whether to update the firmware on personal phones is a personal decision. Some opt for CyanogenMod, while others feel they do not own the device without TWRP or jailbreak. In the case of corporate mobile phone updates, the process should be relatively standardized; otherwise, even Ragnarok would seem like fun to the IT team. Read on to learn how this occurs in the corporate world. A brief overview […]

Organizing effective time attacks using HTTP/2 and WPA3

Posted on

A new hacking technique overcomes the problem of 'network jitter', which can affect the success of attacks through third-party channels. This technique, developed by researchers at Leuven University (Belgium) and New York University in Abu Dhabi, has shown that attackers can exploit network protocol features to orchestrate confidential information leaks. This method, called Timeless Timing Attacks, was demonstrated this year at the Usenix conference, […]

Cisco ISE: Introduction, Requirements, Installation. Part 1

Posted on

1. Introduction Every company, even the smallest, has a need for authentication, authorization, and accounting of users (the AAA protocol family). At the initial stage, AAA is quite effectively implemented using protocols such as RADIUS, TACACS+, and DIAMETER. However, with the growth in the number of users and companies, the tasks increase: maximum visibility of hosts and BYOD devices, multi-factor […]

A vulnerability in Firefox for Android allows control of the browser via public Wi-Fi

Posted on

A serious vulnerability has been identified in the implementation of the SSDP protocol in Firefox for Android, which is used for discovering network services in the local network. This vulnerability allows an attacker on the same local or wireless network to respond to Firefox's probing requests with a UPnP XML 'LOCATION' message containing intent commands, which can open an arbitrary URI in the browser or trigger handlers of other applications. […]

The Raspberry Pi 4 now supports booting from USB drives

Posted on

The default eeprom firmware with a bootloader for Raspberry Pi 4 boards has been enhanced to support booting from USB drives. Previously, Raspberry Pi 4 boards could only boot from an SD card or over the network. Experimental support for USB booting was added in May, but it was unavailable in the default firmware. The initial lack of USB boot capability and […]

Easily manage complex alerts. Or the story behind Balerter.

Posted on

Everyone loves alerts. Of course, it's much better to receive a notification when something happens (or gets fixed) than to sit and look at graphs searching for anomalies. There are quite a few tools created for this. Alertmanager from the Prometheus ecosystem and vmalert from the VictoriaMetrics product group. Zabbix notifications and alerts in Grafana. Custom bash scripts and Telegram bots that periodically trigger some […]

Red Hat is developing a new filesystem NVFS, optimized for NVM memory.

Posted on

Mikuláš Patočka, one of the developers of LVM and the author of several inventions related to optimizing storage system performance, who works at Red Hat, presented in the Linux kernel developers mailing list a new filesystem called NVFS, aimed at creating a compact and fast filesystem for non-volatile memory (NVM, non-volatile memory, such as NVDIMM), combining RAM performance with the capability of […]
