Top 10 ways to protect and secure your data

Operating systems and applications can always be reinstalled, but your data is unique, making it the most valuable asset on your computer or network. With cyber threats and data breaches on the rise, securing your information is more critical than ever. 

“Organizations must now maintain robust privacy measures, including clear privacy policies, opt-out processes, and compliance with consumer protection laws, to mitigate financial and reputational risks,” said IEEE Senior Member Kayne McGladrey.

So, how do you make sure your data stays safe? Here are 10 essential ways to lock it down!

1. Secure Everything with Strong Passwords

Your first line of defence is a strong password policy. Enforce complex passwords, require regular updates, and implement password management tools. Compliance regulations like GDPR mandate stringent password protection, making this step a necessity, not an option.

2. Back Up Your Data Regularly

Cyberattacks, natural disasters, and human errors can result in data loss. Regular, automated backups ensure that your critical information remains recoverable. Consider backup solutions that offer scheduled, selective, and encrypted backups for added security.

3. Keep Your Software Updated

Hackers often exploit unpatched software vulnerabilities. Regular updates ensure your software has the latest security patches and bug fixes. Enable automatic updates where possible to keep your defences up-to-date.

4. Use a VPN for Secure Connections

A Virtual Private Network (VPN) encrypts your internet traffic, shielding your data from prying eyes. This is especially important for employees working remotely or accessing sensitive business files while traveling. Opt for a reputable, paid VPN for reliable security features.

5. Install Antivirus Software

Modern antivirus solutions protect against ransomware, spyware, and other cyber threats. Windows 10 and macOS offer built-in protections, but additional layers of security – such as advanced malware protection – can further safeguard your data.

6. Enable Multi-Factor Authentication (MFA)

MFA adds an extra layer of security by requiring a second verification step, such as a one-time code sent to a mobile device. This significantly reduces the risk of unauthorised access.

7. Implement Public Key Infrastructure (PKI)

PKI enhances security by encrypting data with public/private key pairs. Only authorized recipients can decrypt the information, making it a highly effective method for securing sensitive communications and transactions.

8. Hide Data with Steganography

Steganography embeds confidential data inside other file formats, such as images or audio files. While this doesn’t encrypt data, it provides an additional layer of concealment, particularly when used alongside encryption tools.

9. Educate Employees on Cybersecurity Best Practices

Human error is one of the leading causes of data breaches. Training employees to recognise phishing scams, avoid suspicious links, and follow security best practices significantly reduces risks.

10. Seek Professional Guidance

If your organization handles large amounts of sensitive data, consider consulting cybersecurity professionals. Managed security service providers (MSSPs) offer 24/7 monitoring, threat detection, and compliance support to keep your data safe.

The Growing Privacy Challenge of AI

Generative AI introduces new data security concerns. As Oliver Friedrichs, CEO of Pangea, warns, “Every enterprise integrating AI faces an unprecedented privacy challenge: they’re essentially creating a bridge between their company’s confidential data and public AI models.” 

Unauthorised access to AI-generated insights can result from inadequate security measures. Organizations should implement strict access controls and data masking techniques to prevent sensitive information from being exposed.

Cybersecurity isn’t a one-and-done deal – it’s an ongoing effort. Stay proactive, keep learning, and make data protection a top priority. Your future self will thank you.
