For Linux operating system (OS) kernel updates, which include “Availability requirements important new security enhancements and bug fixes, releases happen about 1 are on the rise for once per month. These updates help keep systems current with the latest organizations undergoing innovations. However, manually patching systems has many inherent digital transformations. challenges and difficulties which tends to delay their timely application.

In this paper, Oracle Ksplice’s capabilities and many infrastructure downtimes advantages are explained. costing $100,000 per hour on an average. With Why Patching Matters the possibility of every organization being a Inadequate patch management can leave loopholes in the IT infrastructure leading to target for cyberattacks various security and performance issues. Ideally, patches should be applied shortly after and attackers moving very release to ensure the latest system protections. Patching typically requires downtime quickly to exploit system which, depending on operations, can require weeks or months of advanced planning. vulnerabilities, IDC Most Linux patching also traditionally happens at the disk level for file systems, which has recommends several disadvantages. -

How Solarwinds Patch Manager Can Help the NHS Avoid Ransomware Attacks
WHITE PAPER How SolarWinds Patch Manager Can Help the NHS Avoid Ransomware Attacks page 1 How Solarwinds Patch Manager Can Help the NHS Avoid Ransomware Attacks In May of 2017, the WannaCry virus took a dramatic toll on the U.K.’s National Health Service (NHS)—the largest single-payer healthcare system in the world. According to a report released by the National Audit Office (NAO)*, the attack is believed to have infected machines at 81 health trusts—which accounts for nearly one-third of NHS trusts in the U.K. In addition, according to the report, 19,500 medical appointments were cancelled, computers at 600 general practices were locked, and five hospitals had to divert ambulances to other medical facilities. WannaCry works by infecting an organisation’s infrastructure and encrypting its data, then requiring a ransom payment to unencrypt the data and have it be accessible once again. “The WannaCry cyberattack … was a relatively unsophisticated attack and could have been prevented by the NHS following basic IT security best practice,” stated Amyas Morse, head of the National Audit Office, in conjunction with issuing the report. “There are more sophisticated cyberthreats out there than WannaCry, so the NHS needs to get their act together to ensure they are better protected against future attacks.” According to the report, the vulnerability was able to penetrate the system because of a lack of patching. Patches are provided by vendors to resolve known vulnerabilities. THE VALUE OF PATCH MANAGEMENT Patch management is a basic IT security function. The value in performing regular patch management is undeniable, particularly as IT vendors make it easier and easier to implement. -
Porting Linux Embedded Linux Conference (Europe)
Porting Linux Embedded Linux Conference (Europe) Porting Linux About Jon Masters ● Been playing with Linux for 14 years (and the kernel for 13 of those), since the age of 13. ● Built embedded NMR scientific instruments, worked with Montavista UK, now at Red Hat. ● Author of the LKML Summary Podcast and the kernel column in Linux User & Developer. ● Co-author of Building Embedded Linux Systems (second edition) – O'Reilly (2008) ● My car still has an empeg :) Porting Linux Overview ● Why port Linux anyway? ● Background pre-requisities ● Early board work ● Bootloader bringup ● Initial kernel bringup ● Debugging ● Working with Upstream ● Trends Porting Linux Why port Linux anyway? ● Linux is very portable ● Supports 23 architectures in the upstream “mainline” kernel tree of Linus Torvalds. ● Kernel is mostly written in C, with some assembly (most architectures only need a dozen such files) ● Split between high-level generic functions and low- level functions to abstract architectural differences. Porting Linux Why port Linux anyway? ● Linux is competitive ● The number of Linux kernel developers contributing to the official kernel has tripled since 2005. ● Feature growth continues with an average of 10K new lines of source code added every day. ● In the hour you spend here 5.45 patches will on average be added to the upstream Linux kernel. ● Source: Linux Foundation analysis Porting Linux Why port Linux anyway? ● Linux is cost effective. ● A large amount of code to build upon. ● Large (growing) community of developers. ● I think we all know the rest. Porting Linux Background pre-requisities ● Hardware ● Development board or simulator – Optional debugger, some kind of UART – Boards range in value from $200-$crazy – Implement the same architecture and platform as the final design but maybe with a number of hacks. -
Xerox Security Bulletin XRX21-012 (July 28, 2021)
Xerox Security Bulletin XRX21-012 Xerox® FreeFlow® Print Server v2 / Windows® 10 Install Method: USB Media Supports: • Xerox® iGen®5 Press • Xerox® BaltoroTM HF Production Inkjet Press • Xerox® BrenvaTM HD Production Inkjet Press Deliverable: July 2021 Security Patch Update Includes: OpenJDK Java 8 update 302-b08 Software Bulletin Date: July 28, 2021 1.0 Background Microsoft® responds to US CERT advisory council notifications of Security vulnerabilities referred to as Common Vulnerabilities and Exposures (CVE’s) and develops patches that remediate the Security vulnerabilities that are applicable to Windows® 10 and components (e.g., Windows® Explorer®, .Net Framework®, etc.). The FreeFlow® Print Server organization has a dedicated development team, which actively review the US CERT advisory council CVE notifications, and delivers Security patch updates from Microsoft® to remediate the threat of these Security risks for the FreeFlow® Print Server v2 / Windows® v10 (supporting the Integrated and Standalone platforms) The FreeFlow® Print Server organization delivers Security Patch Updates on the FreeFlow® Print Server v2 / Windows® v10 platform by the FreeFlow® Print Server organization on a quarterly (i.e., 4 times a year) basis. The FreeFlow® Print Server engineering team receives new patch updates in January, April, July and October, and will test them for supported Printer products (such as iGen®5 printers) prior to delivery for customer install. Xerox tests FreeFlow® Print Server operations with the patch updates to ensure there are no software issues prior to installing them at a customer location. Alternatively, a customer can use Windows® Update to install patch updates directly from Microsoft®. If the customer manages their own patch install, the Xerox support team can suggest options to minimize the risk of FreeFlow® Print Server operation problems that could result from patch updates.
