Keeping your Windows device secure

Microsoft Windows is a powerful operating system, but it can be vulnerable to security threats if not properly maintained. The tips below will help you keep your device secure and up-to-date.

Antivirus
Windows Defender is built into modern versions of Windows and provides real-time protection against viruses and malware. For devices running Windows 7, Microsoft Security Essentials is available as a free download. Additional antivirus software is generally not necessary.

Updates
Regularly updating your operating system and software is one of the most effective ways to secure your device. Enable automatic updates to ensure you receive the latest security patches.

Windows offers several configurable settings that can enhance your device’s protection:

Secure Windows Accounts
Rename the default Administrator account to prevent common attacks. For added protection, consider creating a decoy administrator account without privileges to confuse potential intruders.

Account Lockout Policy
Configure your device to temporarily lock user accounts after a set number of failed login attempts. This helps prevent brute-force attacks.

Strong Passwords
Use complex passwords or passphrases with at least 16 characters, including a mix of letters, numbers, and symbols. Avoid using personal information, such as names or birthdates, as they can be easily guessed.

Download Cautiously 

  • Only download files from trusted sources.

  • If you receive an unexpected file—even from someone you know—verify its legitimacy before downloading.

  • Avoid software downloads from unknown or unverified websites.

  • Watch for unwanted add-ons or changes to your system settings during installation.

  • Disable or remove any suspicious or unnecessary apps.

  • Use browser extensions like Web of Trust (WOT) to help identify and avoid malicious websites.

Secure Links

  • Type URL’s directly or use bookmarks rather than clicking on links in emails or messages.
  • Hover over links before clicking to preview the destination URL (usually displayed in the bottom corner of your browser).
  • Only enter sensitive information on websites with a padlock icon in the address bar—this indicates a secure connection.

Secure Browsers
Use secure browsers like Mozilla FireFox and Google Chrome as alternatives to Internet Explorer for enhanced protection and regular security updates.

Encrypt Your Files
Add an extra layer of protection by encrypting sensitive files or your entire hard drive. Tools like Entrust, digital signatures, or built-in encryption features in Microsoft Office can help safeguard your data.

MoveIT
Use MoveIT, a secure web-based file transfer platform, to send and receive sensitive files safely.
