Keeping your operating system (OS) up-to-date is essential for security, performance, and compatibility. However, updating your OS can also be challenging, time-consuming, and risky. How can you ensure your OS is kept up-to-date without compromising your system or workflow? Here are some tips and best practices for system administrators.
The first step is to choose the right OS version for your needs and preferences. Different OS versions may have different features, requirements, and support cycles. For example, Windows 10 has several editions, such as Home, Pro, Enterprise, and Education, each with different capabilities and update policies. Linux distributions also vary in their stability, frequency, and methods of updates. You should research and compare the OS versions that suit your hardware, software, and goals before installing or upgrading.
Ensuring your operating system stays up-.to-date is key for security and performance. Begin by choosing the right OS version, configure update settings, and routinely back up your data. Monitor the update process closely, review results, and embrace continuous learning for ongoing improvement. Explore additional considerations for a comprehensive strategy.
First you should ensure you are installing a supported OS version which will it is still under the coverage of the maintenance and updates. Second deploy of internal clear policies to manage the updates and schedules. Scan your farm for any missed updates by using any from the vulnerability tools. Apply the updates from a trusted source and assure you testing the releases enough before deploying them into production system. Finally Monitor updates results and assure none from the assets had not been covered or patched, also re-try any failed updates after applying required adjustments.
Some are the processes, Backup your files Ensure system OS are patched regular either as domain connected system/ workgroup, after the available updates has been reviewed or tested
OS Version Quest ??? Define Needs and Preferences: Outline your specific requirements and preferences. Research Features and Support: Explore features, requirements, and support cycles of different OS versions. Windows Example: For Windows, understand editions like Home, Pro, Enterprise, and Education. Each edition has unique capabilities and update policies. Linux Landscape: Linux distributions vary in stability, update frequency, and methods. Choose based on your hardware, software, and goals. Informed Decision: Research thoroughly before installing or upgrading. Align your choice with hardware compatibility and long-term objectives. Choosing the right OS version sets the foundation for a smooth and tailored computing experience! ??
Para mantener actualizado un sistema operativo, es importante instalar las últimas actualizaciones de software. En el caso de Windows, puedes hacerlo de forma automática o manual. Para actualizar un sistema operativo, es importante seguir los siguientes pasos: 1. Verifica la versión de tu sistema operativo. 2. Verifica si hay actualizaciones disponibles en la configuración de tu sistema operativo. 3. Descarga e instala las actualizaciones disponibles. 4. Reinicia tu equipo para aplicar los cambios.
The next step is to configure the update settings for your OS. Most OSes have options to customize how and when updates are downloaded, installed, and applied. You should balance the trade-offs between convenience, control, and security. For example, you can enable automatic updates to save time and ensure you get the latest patches, but you may also want to defer or pause updates to avoid interruptions or conflicts. You can also use tools like Windows Update for Business or Linux package managers to manage updates across multiple devices.
Enable automatic updates and check for updates regularly. Set up notifications to stay informed. Update third-party software. Use a package manager for Linux. Apply security patches promptly. Back up data before major updates. Keep firmware and BIOS updated. Consider long-term support (LTS) versions for stability. Finally, stay informed about security issues and updates.
Enable automatic updates whenever possible. Most modern operating systems provide options for automatic downloading and installation of updates. Configure update schedules during non-business hours to minimize disruption to users.
Enabling automatic updates is the best way to ensure that all OSs are up-to-date and less susceptible to attacks, but there is always the risk of breaking something inadvertently. Therefore, I suggest that you have a desktop/laptop setup with the same configuration as your office laptops, and always update that machine first, before rolling out the update throughout the organization. That way, you can see how the OS reacts to the update without worrying about halting the office's routine. In addition, I believe that updates should be downloaded to a server first, and distributed from there in order to preserve internet bandwidth.
Mastering Update Harmony ?? Customize Update Preferences: Configure how and when updates are downloaded, installed, and applied. Balance Convenience and Control: Find the sweet spot between convenience, control, and security. Automatic Updates: Enable for timely security patches and enhancements. Balance with potential interruptions. Deferred or Paused Updates: Defer or pause updates to avoid interruptions or conflicts. Optimize for your workflow. Specialized Tools: Utilize tools like Windows Update for Business or Linux package managers. Manage updates efficiently across multiple devices. Balancing updates ensures your system stays secure without disrupting your workflow. Customize wisely! ?????
Configure proper patch setting on your Patch management solution. You need to ensure that your UAT or testing environment is properly tested. Autoupdate is not a solution here. Some updates can ruin your system if not tested properly. Therefore, configure proper patch setting for the patches to be deployed on UAT first follow by Production to avoid business impact.
The third step is to backup your data and system before applying any updates. Updates can sometimes cause errors, crashes, or data loss, so you should always have a backup plan in case something goes wrong. You can use external drives, cloud services, or software tools to create backups of your files, settings, and system image. You should also test your backups regularly to make sure they are working and accessible. Backing up your data and system can help you recover from any update issues and minimize downtime.
Before applying major updates or patches, ensure that reliable system backups are in place. This precautionary measure allows for a quick recovery in case an update causes unforeseen issues. Regularly test the restoration process to confirm the integrity of backups.
Backup Ballet ???? Pre-Update Backup Routine: Always backup data and system before updates. Error and Data Loss Safeguard: Updates might lead to errors or data loss; be prepared. Backup Methods: Use external drives, cloud services, or software tools. Backup files, settings, and system images. Regular Testing: Test backups regularly to ensure functionality. Confirm backups are accessible and reliable. Downtime Minimization: In case of update issues, backups aid quick recovery. Minimize downtime and keep your workflow smooth. Backup your way to peace of mind—ready for any update twists! ????
Al igual que en el paso anterior, hay que tener previamente una copia de los sistemas antes de realizar las actualizaciones. En todo entorno, siempre tenemos las copias automatizadas por lo que ajustar esta parte es un paso relativamente sencillo. Por mi experiencia, sistemas de copia como Commvault/Metallic tienen la suficiente potencia como para acometer esta tarea tanto en entornos on-premise como en la Cloud.
Before major OS updates, create a backup of your important data. While rare, updates can sometimes cause issues, and having a backup ensures you can revert if needed. Sometimes, updates might introduce changes that could affect compatibility with certain applications or hardware.
The fourth step is to monitor the update process and check for any problems. Updates can take a long time to complete, depending on the size, type, and number of updates. You should avoid interrupting or shutting down your device during the update process, as this can cause corruption or damage. You should also monitor the progress and status of the updates, and look for any error messages or warnings. If you encounter any issues, you should troubleshoot them as soon as possible, or contact the OS vendor or support team for help.
Frequent monitoring of the update process is essential to address potential issues and maintain system integrity. In some cases, updates may encounter compatibility issues with specific hardware or software configurations, leading to unexpected errors or malfunctions. By actively monitoring the update process, users can identify any anomalies, that may indicate a problem A notable example is the "Blue Screen of Death" (BSOD) on Windows systems, which can occur during certain update processes if there are compatibility issues or conflicts. Timely attention to such issues allows users to troubleshoot and resolve problems promptly, reducing the risk of system instability or data loss associated with interrupted or faulty updates.
It is necessary to monitor the update process due to multiple reasons. The update might fail due to various reasons like network issues, conflicts with other software, or insufficient space on the device. Monitoring helps catch these failures early, allowing you to take corrective actions. Also watching updates lets you know how much of your computer's energy they're using. Some updates are like big eaters—they use a lot of your computer's power and might need a restart. Knowing this helps you choose when to update, so it doesn't bother you.
Update Watchtower ???? Patience is Key: Updates take time; size and type impact duration. Avoid interruptions or shutdowns for a smooth process. Avoid Interruptions: Don't interrupt or shut down during updates. Prevent potential corruption or damage. Active Monitoring: Keep an eye on the update progress and status. Look out for error messages or warnings. Swift Troubleshooting: If issues arise, troubleshoot promptly. Contact OS vendor or support for assistance. Stay vigilant during updates to ensure a seamless and trouble-free process! ???
Implement a centralized patch management system to streamline the process of deploying updates across multiple devices. Utilize tools that allow administrators to schedule, monitor, and control the deployment of patches on a network-wide scale.
Otro de los pasos importantes de una actualización es la supervisión del resultado de las pruebas que ejecutamos primeramente en QA. Esto no garantiza que todo vaya a funcionar 100% en producción pero en gran medida minimiza problemas imprevistos y hace que las actualizaciones en los sistemas de producción estén mucho más controladas. Podemos definir unas ventanas de mantenimiento apropiadas en caso de ser necesarias en sistemas críticos. La generación de informes de cambios, tener un buen sistema de monitorización es básico también para este punto
The fifth step is to review the update results and verify that everything is working as expected. Updates can sometimes change or remove features, settings, or drivers, so you should check that your system and applications are functioning properly after the updates. You should also review the update history and logs, and note any changes or improvements. If you are not satisfied with the updates, or if they cause serious problems, you may have the option to roll back or uninstall them, depending on the OS and update type.
Post-Update Inspection ???? Verification Check: Ensure everything works as expected post-update. Verify system and applications functionality. Feature and Setting Review: Check for changes or removal of features, settings, or drivers. Confirm everything aligns with expectations. Update History and Logs: Review update history and logs. Note any changes or improvements. Rollback Options: If unsatisfied or issues arise, explore rollback or uninstall options. Some OSes offer the flexibility to revert updates. Post-update scrutiny ensures a smooth sailing experience. Confirm, adapt, and embrace the improvements! ????
Checking out the updates helps you know what's changing in your system. It's like getting the scoop on any new stuff—features, betterments, or tweaks happening in your software or how your computer works.
If you're updating for a business. Update specific IT Department machines first to allow for a controlled test of the update. If possible, then roll out the update gradually to select users, so issues caused by the update can be identified quickly and only small numbers of users are affected by problems.
The final step is to keep learning and improving your OS update skills and knowledge. Updates are constantly evolving and changing, so you should stay informed and updated about the latest OS news, trends, and best practices. You should also seek feedback and advice from other system administrators, and share your own experiences and tips. You can use online forums, blogs, podcasts, or courses to learn and improve your OS update skills and knowledge. Keeping your OS up-to-date is not a one-time task, but an ongoing process that requires attention and care.
In addition to the OS and software updates, periodically check for firmware or BIOS updates for your computer's hardware components. These updates can address hardware-related issues and improve system stability.
Add item: Regularly Reboot Systems. Regularly reboot systems as many updates require a system restart to take effect. Schedule regularly reboots, ensuring pending updates are applied.
Modern Linux Kernels have the capacity to apply kernel and application patches without the need for a reboot. Samples are withnthr use of kgraft and kpatch which changes the code in memory aside form the binaries that are within the packages.
Automation is key when it comes to keeping operating systems and applications updated. Explore the best way to do this for your environment, and monitor it, and it will make tracking the effectiveness easier, ensuring compliance, and protecting your security posture.
Always have at least 2 kernels and 1 of them is the one that works correctly since you can update a kernel and it will override the one that was working and the new one will have a kernel panic and not be able to launch the operating system anymore. That is why it is essential to have 2. Checking disk space is essential to have a healthy system, do not leave old files or backups inside the server or desktop, always keep them outside of it. Do not restart the computers "because something does not work" but look for the cause that produced it, an update may have been the cause or some symbolic link that changed. Reading the logs is important to know and understand our operating system, it is an ally that we have don't neglect it.
Having software version monitoring in palce hugely helps to plan and prioritise updates. Also moving to "more cattle less pets" mindset - where instead of continuous updates you regularly scrap older OS versions and reinstall/restore your systems with newer and up2date patch levels helps to reduce variance. While in theory OS that is upgraded from v5 -> v6 -> v7 should be same as freshly installed and configured v7 - in practice there are differences.
Tenable Nessus is a great tool for detecting vulnerabilities in your environment including operating system vulnerabilities which can be mitigated with a version update. This is one way to detect cracks in your patching process which could be a specific machine issue or something more widespread. Either way OS patching is important as every day it is left unpatched is an attack waiting to happen.
