What are the best practices for securing a computer's BIOS?

It's the most basic and oldest solution of them all, but still the first obstacle to an attempt to unauthorized entries to the BIOS/UEFI

Craft strong, unique passwords: 12+ characters, mix of upper/lower cases, numbers, symbols. Enable 2FA: Extra login security with codes or biometrics. Update software: Patch vulnerabilities hackers exploit. Guard your info online: Limit personal details shared publicly. Stay vigilant against phishing: Don't click suspicious links or attachments.

- mot de passe de longueur suffisante ( + de 12) - suite de mots sans aucun rapport (ex: chat voiture travail enfant) - les espaces comptent comme caractère special - changer régulièrement de suite de mots

Las contraseñas seguras son esenciales para proteger nuestra información personal y nuestras cuentas de los ataques de personas inecrupulosas. Yo recomiendo: Usar al menos 8 caracteres, incluyendo letras mayúsculas y minúsculas, números y símbolos especiales. Evitar usar palabras comunes, nombres propios, fechas importantes o información personal que se pueda encontrar fácilmente en internet o en las redes sociales. No usar la misma contraseña para diferentes cuentas o servicios. Si una de nuestras contraseñas se ve comprometida, las demás también podrían estar en peligro. Cambiar las contraseñas periódicamente.

Set a strong password. Enable secure boot. Update your BIOS regularly. Disable unused ports and devices. Be the first to add your personal experience. Enable tamper detection. Backup your BIOS settings. Here's what else to consider.

Usar senha BIOS: Defina uma senha forte para acessar o BIOS. Isso impede que usuários não autorizados alterem as configurações do BIOS ou inicializem a partir de dispositivos não autorizados.

If you set the BIOS password, which is considered a first best practice, make sure to write it down at a safe place. Forgetting it will at least give you a lot of inconvenience. Also make sure to match the keyboard layout used by the BIOS, usually US_English at that stage.

Best practices for securing a computer's BIOS: - Enable a BIOS password. This prevents unauthorized access to the BIOS setup utility where settings can be changed. - Enable UEFI Secure Boot. This verifies the integrity of the boot process and only allows authorized operating systems to load. - Disable unused BIOS features like wake-on-LAN, PXE boot, and USB mass storage to reduce attack surface. - Update the BIOS firmware regularly. Manufacturers release updates that fix vulnerabilities. - Disable external ports like USB when not in use to prevent physical access to the BIOS.

Setting a password is always good to include the letters (Capital & Small), numbers and symbols. E.g Freedom@21# Ensure the password is easy to remember.

Securing your computer’s BIOS is crucial for maintaining the overall security posture of your system by configuring robust BIOS passwords to prevent unauthorized access to the BIOS settings.

Here are some additional benefits of using secure boot: 1. Can help to prevent unauthorized operating systems from being installed on your computer. 2. Can help to improve the performance of your computer by preventing unnecessary software from loading during startup. 3. Can help to protect your privacy by preventing unauthorized software from accessing your data.

Segun mi experiencia, habilitar el arranque seguro evita que se ejecuten códigos maliciosos o erróneos desde el inicio de ciclo de encendido del computador, es una buena práctica y ya viene implementada en la mayoría de las boards actualmente.

Usar Boot seguro (Secure Boot): Ative a opção de inicialização segura, se disponível. Isso garante que apenas o software confiável e assinado digitalmente seja executado durante o processo de inicialização.

Add BitLocker or some sort of encryption program to secure the hard drive in the event that the device is taken. Adding this level of security allows for devices to be remotely wiped or kept secure.

Actualizar la BIOS también es una de mis practicas favoritas ya que corrige errores, conflictos y previene de vulnerabilidades. De igual forma mantener una copia del archivo BIOS actual antes de actualizar a una nueva versión previene de dejar el computador como un pisapapeles.

This needs the same attention as Operating System Updates, update your BIOS regularly. Download the updates only from the vendors support pages and always check the hash values of the downloaded files.

I think this is the most important step you have to keep in mind. If there is a security flaw or some hardware problem a bios update can fix that and restore flawless operation.

Something I see often in laptops is the end user doesn't know or does not do updates, and if they check for updates, and then look in the hidden folder for major updates they will find BIOS updates need to be done, its good to do this, but if done wrong, for example, downloading and installing this updater and the power goes off laptop you're in trouble somewhat. These BIOS updates help make a system better to run and are in my opinion crucial to the motherboard as make it better to perform and run system programs, software, and performance.

Having control over the computer ports is a key factor in security. Many attacks occurred because of external devices therefore access to such devices needs to be controlled and granted on a need basis only.

The most important thing to disable are BIOS updates over the air (OTA). Also booting the device via the network should be disabled or at least behind a password barrier.

Here are some best practices for securing a computer BIOS: 1. Update BIOS firmware regularly. 2. Set a strong BIOS password. 3. Disable booting from external devices. 4. Enable Secure Boot if available. 5. Enable BIOS write protection. 6. Ensure physical security of the computer. 7. Backup BIOS settings regularly. 8. Follow vendor recommendations. 9. Monitor BIOS logs for unauthorized changes. 10. Implement endpoint security measures like antivirus software and firewall protection.

Ter controle e conhecimento de quais portas estão habilitadas no hardware é essencial para garantir um ambiente seguro no computador. Portas USB podem não apenas ser usadas por perifericos mas também como conexões a discos onde uma BIOS diferente ou em outra versão pode ser “flashada”, colocando o sistema em uma possível posição de vulnerabilidade. Atenção a conexões SATA que não estão em uso, assim como M.2 e SD/Micro SD Slots.

I think tamper protection is a good thing as will stop users from accidentally pressing delete and making a change and then the system can go very wrong. I see it often in my work here. Accidentally pressed DEL upon startup, thought oh what is this, and made some changes not realising that it is bad to change things in BIOS if you don't know what you're doing.

One of the most important aspects of safe guarding bios apart from password protection and secure boot is to backup ur BIOS.. and keep it easily accessible.

Always use a password, something you remember. Back up the default settings, if it supports exporting the settings file so do so. You can always revert to default settings. Remember, use the manuals / any other reliable guides before "messing stuff up", it can go down to your OS or files or even bricking your device.

Consider using devices where you can flash an alternative BIOS like coreboot and disable the ubiquitious Intel Management Engine. The highest level of security can only be achieved when you control the boot process from the very beginning on and have control over the BIOS code itself.
