How to Secure a New Computer

Setting up a new computer is the ideal time to establish strong security and privacy from the start. A handful of steps during setup protect your data, accounts, and privacy going forward. This guide walks through how to secure a new computer, in plain terms.

Secure the Device Itself

Start with device-level security:

• Set up a strong login: Use a strong password (or PIN/biometrics where supported) to log into your computer, and require it on wake.
• Enable automatic updates: Turn on automatic updates for your operating system and software, applying security patches promptly — one of the most important protections.
• Enable security software and firewall: Ensure security/antivirus software is enabled (modern systems include capable built-in protection) and your firewall is on.
• Enable disk encryption: Enable disk encryption (available on modern systems) so your data is protected if the device is lost or stolen.
• Set up find-my-device: Enable device location/find-my-device features where available.

Secure Your Accounts

Your accounts are central:

• Secure your main account: Use a strong, unique password and 2FA on the account tied to your computer (your platform/ecosystem account).
• Secure your email: Ensure your email has a strong password and 2FA, since it is the key to your other accounts.
• Set up a password manager: Install a password manager to manage strong, unique passwords across your accounts.
• Enable 2FA on important accounts: Set up 2FA (ideally app-based) on important accounts as you sign in.

Configure Privacy Settings

Set up privacy from the start:

• Review privacy settings: Go through your operating system's privacy settings, disabling data collection, telemetry, and sharing options you are not comfortable with.
• Manage app permissions: Grant apps only necessary permissions.
• Configure your browser for privacy: Set up your browser with privacy in mind (block third-party cookies, adjust settings, consider privacy extensions), since the browser is central to your activity.
• Limit ad/personalization tracking: Limit advertising and personalization tracking where offered.

Set Up Software Wisely

Be thoughtful about software:

• Install only needed software from official sources: Install software you need from official, legitimate sources (official sites, app stores), avoiding unofficial sources that may bundle malware.
• Remove unnecessary pre-installed software: Remove bloatware or pre-installed software you do not need.
• Keep software updated: Ensure all installed software updates automatically.
• Use a standard account for daily use: Consider using a standard (non-administrator) account for daily use, limiting what malware can do.

Set Up Backups

Protect your data from the start:

• Set up backups: Configure backups using the 3-2-1 approach (multiple copies, including offsite/cloud), so your data is protected from loss, failure, or ransomware.
• Automate backups: Automate backups so they happen regularly.
• Wipe your old computer: Before retiring your old computer, back up its data, sign out of accounts, and securely erase it (wipe/reset, ideally with encryption) so your data does not go with it.

Frequently Asked Questions

What are the essential steps to secure a new computer?

Secure the device: set up a strong login, enable automatic updates (a top protection), ensure security software and your firewall are enabled, and enable disk encryption so your data is protected if the device is lost. Secure your accounts: use strong passwords and 2FA on your main account and email (the key to your other accounts), and set up a password manager. Configure privacy: review your operating system's privacy settings (disabling telemetry and data collection you are uncomfortable with), set up your browser for privacy, and manage app permissions. Install only needed software from official sources, and set up automated backups. These steps establish strong security from the start.

Should I enable disk encryption on my new computer?

Yes, enabling disk encryption (available on modern operating systems) is a valuable protection. It encrypts the data on your computer so that if the device is lost or stolen, your data cannot be accessed without your login credentials — protecting your personal files and information. Modern systems make this straightforward to enable, often during setup or in security settings. Combined with a strong login password, disk encryption ensures your data stays protected even if someone gains physical access to your computer. It is one of the recommended steps when securing a new computer, especially for laptops that travel with you.

How do I set up my new computer for privacy?

Go through your operating system's privacy settings during or after setup, disabling data collection, telemetry, and sharing options you are not comfortable with. Configure your browser for privacy, since it is central to your activity — block third-party cookies, adjust privacy settings, and consider reputable privacy extensions. Grant apps only necessary permissions, limit advertising and personalization tracking where offered, and remove unnecessary pre-installed software (bloatware). Setting these up when the computer is new establishes strong privacy from the start, before you accumulate software and habits, and reduces the data collected about your activity.

Conclusion

Setting up a new computer is the ideal time to establish strong security and privacy from the start. Secure the device itself with a strong login, automatic updates (a top protection), enabled security software and firewall, disk encryption (protecting your data if the device is lost or stolen), and find-my-device. Secure your accounts with strong passwords and 2FA on your main account and email (the key to your other accounts), and set up a password manager. Configure privacy by reviewing your operating system's privacy settings (disabling telemetry and data collection you are uncomfortable with), setting up your browser for privacy, managing app permissions, and limiting ad tracking. Set up software wisely — installing only needed software from official sources, removing bloatware, keeping software updated, and using a standard account for daily use. Finally, set up automated backups (the 3-2-1 approach) to protect your data, and securely wipe your old computer before retiring it. By taking these steps when your computer is new, you establish strong security and privacy that protect your data, accounts, and privacy going forward.
