1 Use Strong Passwords

A strong password is your first line of defense in protecting your online accounts. It should be complex, long, and unique, combining letters, numbers, and symbols. Avoid using easily guessable information like birthdays or common words. Consider using a passphrase—a sequence of words that create a long string of characters—that is both secure and memorable. For added security, change your passwords regularly and never reuse them across different sites. If remembering multiple passwords is challenging, a reputable password manager can securely store and generate them for you.

One way hackers guess the password is through a brute force attack. This involves using all possible password combinations until the correct password is found. What is particularly impressive is how exponentially security increases when long passwords are used. With a computing power of 1 billion attempts per second, a password with 6 lowercase letters can be cracked in a few seconds. In contrast, it takes years to crack a 12-character password. If uppercase letters, numbers and special characters are also used, attackers theoretically need millions of years to guess the password using brute force.

2 Enable 2FA

Two-factor authentication (2FA) adds an extra layer of security beyond a password. It requires you to provide two types of information to access your account: something you know (like a password) and something you have (like a smartphone). Even if someone steals your password, they would still need the second factor to break into your account. Many services offer 2FA options such as a text message code, an authentication app, or a physical token. Always opt-in for 2FA on services that handle sensitive information.

Users should always set up 2-factor authorization if possible. This increases security enormously in the event of a compromised password. In particularly heavily regulated industries such as finance or healthcare, this has already become legal requirements and industry standards. In addition to the classic 2FA authorization via SMS or app, biometric factors such as fingerprint scanners, facial recognition or iris scanners are increasingly being used. There are already initial solutions that do not require passwords at all and are limited to biometric authentication and hardware tokens.

3 Update Regularly

Keeping your software and devices updated is vital for digital privacy. Developers release updates not just for new features, but also to patch security vulnerabilities. Cybercriminals exploit outdated software to gain unauthorized access to systems. Regularly updating your operating system, applications, and antivirus software can close these security gaps. Enable automatic updates where possible to ensure you're always running the latest versions without having to remember to manually update.

4 Use Encryption

Encryption is like a secret code that scrambles your data, making it unreadable to anyone without the key. When you use encrypted services, such as Virtual Private Networks (VPNs) or encrypted messaging apps, your data is protected from eavesdroppers on public Wi-Fi and other unsecured networks. Encrypting your hard drive is also a smart move, especially for laptops or devices that could be lost or stolen. This way, even if someone gets hold of your physical device, they can't access your information without decrypting it first.

5 Limit Sharing

Be mindful of what personal information you share online. Social media platforms and other websites often ask for details that could be used to steal your identity or guess your security questions. Only fill out necessary fields when creating profiles or making online purchases. Regularly review the privacy settings on your accounts to control who can see your information and posts. Be cautious with how much you share about your location, activities, and personal life, as this information can be pieced together to compromise your privacy.

6 Secure Networks

Using secure networks is crucial for protecting your digital privacy. Public Wi-Fi can be convenient but it's often unsecure, making it easy for hackers to intercept your data. Always use a secure, password-protected network for sensitive activities like online banking or shopping. If you must use public Wi-Fi, avoid accessing personal accounts or sensitive data. Alternatively, use a VPN to create a secure connection over a public network, encrypting your data and shielding it from potential intruders.

Another approach to network security is to implement network segmentation where your network access provides the appropriate access to data . This approach requires strict guidelines to what data can be accessed & copied to reports or moved to off-system files / shared outside of corporate security. This also incorporates encrypted files where files require separate key(s) to open or disclose their content.

It is also extremely important to verify the source of information and emails. Email senders and links should be carefully checked before clicking. Phishing emails often have similar URLs with only minimal differences. Poor spelling or urgency ("You will be blocked if you do not respond immediately.") can be signs of phishing. Reputable companies never ask for passwords or sensitive information by email or telephone. File attachments from unknown senders also pose a great risk. These should be checked for malware before opening. Suspicious activities should be reported to the company concerned and to the relevant authorities.
