How do you ensure your PC remains secure after disabling Secure Boot?

Here are some steps to help mitigate the increased risk. Create strong passwords & use 2FA. Antivirus and Anti-malware: Install a reputable antivirus and anti-malware solution with real-time protection and keep it updated. Firewall: Enable your firewall to block unauthorized incoming and outgoing network traffic. Only boot from trusted sources: Be very cautious when booting from external devices like USB drives or DVDs. Only use them from trusted sources and scan them for malware before use.

Regularly install operating system updates, security patches, and firmware updates to protect against known vulnerabilities. Install reputable antivirus software and keep it updated to detect and remove malware. Avoid using an administrator account for daily tasks. Use a standard user account for regular activities to minimize the impact of potential security threats. If your version of Windows supports it, consider encrypting your hard drive with BitLocker to protect your data in case your PC is lost or stolen. Regularly back up your important files to an external drive or cloud storage service to protect against data loss.

Keep Software Updated: Regularly update your operating system and installed software to patch known vulnerabilities. Install Antivirus Software: Use reputable antivirus or antimalware software and keep it up to date to detect and remove threats. Enable Firewall: Configure a firewall to monitor and control network traffic, preventing unauthorized access. Exercise Caution: Be careful with downloads and email attachments, avoiding suspicious sources to prevent malware infection. Use Encryption: Utilize built-in encryption features like BitLocker (Windows) or FileVault (macOS) to protect sensitive data. Strong Passwords and 2FA: Create strong, unique passwords and enable two-factor authentication for added security.

Mantenha seu sistema operacional e software atualizados: Certifique-se de que seu sistema operacional, aplicativos e programas estejam sempre atualizados com as últimas correções de segurança e patches. Isso ajuda a proteger seu PC contra vulnerabilidades conhecidas. Instale um bom antivírus e software de segurança: Utilize um software antivírus confiável e um firewall para proteger seu PC contra malware, vírus e outras ameaças cibernéticas. Certifique-se de manter o antivírus atualizado e realizar verificações regulares no sistema. Faça backup regular dos seus dados: Faça cópias de segurança dos seus arquivos importantes em um local seguro e regularmente.

Absolutely, staying on top of software updates is crucial for maintaining a secure digital environment. Regular updates ensure that your operating system and applications are equipped with the latest security patches, minimizing the risk of exploitation by cyber threats. Enabling automatic updates and conducting regular manual checks are proactive measures to safeguard your PC and sensitive information. It's not just about protecting your system; it's about protecting your digital presence.

Regular updates are vital for security. On my PC, I set updates to install automatically, ensuring I’m protected against the latest threats. This includes not only OS updates but also updates for applications and drivers, which can be just as critical.

Keeping the firewall enabled has been a lifesaver, especially when browsing unfamiliar websites or using network-connected applications. The firewall acts as a barrier against unauthorized access, monitoring incoming and outgoing traffic for potential threats.

Adjusting your PC's security settings to match your usage needs is paramount for maintaining a secure computing environment. Disabling auto-run features and setting User Account Control (UAC) to its highest level are proactive steps to mitigate the risk of unauthorized access and potential malware threats. By being vigilant and implementing these measures, you add an extra layer of defense against cyber attacks and ensure that your PC remains safeguarded against potential security breaches.

Here's my perspective, focusing on the tradeoffs you've made by disabling Secure Boot: You're Now the Bootloader's Bodyguard: It can't protect itself anymore, so you need to be extra vigilant about what you allow to run at startup. "Trusted Software" Is Now on You: Secure Boot's list was imperfect, but it was something. You need to be extra diligent about software sources and update practices. The Human Is the Weak Link: All it takes is one misclick on a malicious link, and your strict config won't matter. Training and vigilance are now more vital.

Safe browsing habits are fundamental. I use ad-blockers and avoid clicking on suspicious links. Additionally, using secure, privacy-focused browsers and extensions has significantly minimized my exposure to online threats.

Absolutely, regularly backing up your important data is a cornerstone of good digital security hygiene. By storing backups on an external drive or a secure cloud service, you're creating a safety net against potential data loss due to malware attacks or system compromises. Making backup routines habitual and verifying their completeness and integrity ensures that you can quickly recover vital files in the event of an unforeseen incident. This proactive approach to data protection is especially crucial in environments where Secure Boot isn't utilized, providing an extra layer of resilience against cyber threats.

Regular data backups have been my safety net against data loss from cyber-attacks or hardware failures. I use both an external hard drive and cloud storage to keep my critical data duplicated and accessible from anywhere, ensuring that I can recover quickly even after a security breach.

Make sure - you have secure update (signature verification of the package) - your update server itself is secure - the OS is loading from a secure memory region (more pertinent to OT microcontrollers). This way the only attack vector that is left is if someone physically overrides contents in your HW. For that get a machete.

If you are disabling secure boot it should be in response to an evident and extreme need. The need to do this generally means you do not need the device for daily use and it is a unique build. The best defense is to limit it's use and network access to your environment. Disabling secure boot should not be a standard response to enabling your workforce.
