Why Data Security Should Be Everyone’s Priority

Robin October 8, 2025 0

Enable Two-Factor Authentication (2FA)

Two-factor authentication (2FA) adds an extra security layer by requiring a second verification step beyond your password. Most major services, such as Google and Microsoft, let you enable 2FA in your account settings. Common methods include SMS codes, email confirmations, or dedicated authentication apps like Authy. Even if a hacker obtains your password, 2FA makes unauthorized access far more difficult. Enabling 2FA on your most sensitive accounts is a simple, highly effective step everyone should take to enhance data security.

Keep Software and Devices Updated

Regularly updating your software and devices is essential for closing security gaps exploited by cybercriminals. Updates often include patches for vulnerabilities discovered by developers and security experts. To ensure you’re protected, enable automatic updates on operating systems—like Windows via Windows Update—and on your apps and smartphones.

Ignoring or delaying updates leaves your devices exposed to known threats. Take a proactive approach: set updates to install automatically whenever possible and regularly check for pending updates to minimize your risk of falling victim to preventable attacks.

Educate Yourself on Phishing and Social Engineering

Phishing and social engineering are common tactics attackers use to trick individuals into revealing sensitive information. Learn to spot suspicious emails, unexpected attachments, and links—often disguised as urgent requests or official communications.

Be cautious with unsolicited phone calls asking for personal details. Resources like FTC’s guide on phishing scams can help you stay informed. Regularly educating yourself and others about these threats is a powerful defense, as awareness significantly reduces the risk of accidentally compromising your data or your organization’s security.

Secure Sensitive Data with Encryption

Encryption protects your sensitive data by converting it into unreadable code, accessible only with the correct key or password. For local storage, enable device encryption features such as Windows Device Encryption or Apple’s FileVault.

When transmitting data online, choose services that use end-to-end encryption, like Signal for messaging. By securing both stored and transmitted data, encryption adds a robust shield against unauthorized access, ensuring that even if your information is intercepted or stolen, it remains protected.

Regularly Backup Important Data

Backing up your important data regularly is crucial for recovery after incidents like ransomware, accidental deletion, or hardware failure. Follow the NIST backup guidelines by saving copies to both cloud storage (such as Backblaze) and physical devices like external hard drives.

Schedule automatic backups weekly or daily, depending on your needs. Always secure your backup locations with passwords and encryption to prevent unauthorized access. Consistent and secure backups ensure you can quickly restore your data and minimize the impact of unexpected data loss events.

Limit Data Sharing and Permissions

Minimizing the amount of personal or business information you share online significantly reduces your exposure to data risks. Regularly review privacy settings on social media platforms and adjust app permissions on your devices—only grant access to information that’s strictly necessary.

Use resources like Google’s permissions dashboard to manage connected apps and services. Be cautious when sharing sensitive details, even with trusted contacts. By proactively controlling access and sharing, you reduce the chances of unauthorized use or accidental leaks, reinforcing your overall data security posture.

Monitor Accounts and Respond to Suspicious Activity

Regularly monitor your accounts for signs of unusual activity, such as unexpected login attempts or changes to account details. Enable security alerts and notifications through services like Have I Been Pwned to track breaches involving your credentials.

If you notice suspicious behavior, immediately change your passwords and review your account permissions. Report incidents to the relevant provider—most platforms offer dedicated pages for Google account recovery. Quick, decisive action can limit damage and prevent further unauthorized access, making vigilance a vital aspect of data security.
