IT security in the run-up to Christmas: Protect yourself from digital threats

1. Strong passwords: your first line of defence

Passwords are often the weakest link in the security chain. Weak or reused passwords make it easy for criminals to take over accounts and steal identities.

How to protect yourself:

• Create strong, unique passwords for each account. Use a combination of upper- and lower-case letters, numbers and special characters.
• Use a password manager to securely generate and store complex passwords.
• Enable two-factor authentication (2FA) for added security, particularly for email, financial and online shopping accounts. A code sent via an app or text message, as well as biometric authentication, makes it harder for attackers to gain access to your account.

2. Protection against social engineering: Be vigilant and sceptical

Social engineering is one of the most common methods of attack, particularly in the run-up to Christmas. Attackers use emotional messages or a (fabricated) stressful situation to deceive people. Examples include purported appeals for donations, delivery notifications or prize draws designed to steal personal data or spread malware.

How to protect yourself:

• Check suspicious emails or messages carefully. Be particularly wary of emotional appeals or unusual payment requests.
• Check sender addresses and URL links for authenticity (look out for spelling mistakes or unusual domains, and do not click on links if you are unsure).
• Do not disclose any sensitive data unless you are absolutely certain that the sender is trustworthy.

3. Backups using the 3-2-1 method: your insurance against data loss

Data loss due to ransomware or hardware failures is an ever-present risk. With the tried-and-tested 3-2-1 backup method, you’ll be well prepared. Here’s how the method works: Create three (3) copies of your data: one main copy and two backups. Use two (2) different storage types: for example, an external hard drive and a cloud service. For maximum security, store one (1) copy outside your network.

How to protect yourself:

• Set up regular, automated backups on different backup media.
• Check the recoverability of your backups regularly to ensure they work when you need them most.
• Encrypt your backups to protect them from unauthorised access.

4. Secure end devices: Protect your devices from attacks

Unsecured or out-of-date systems make it easy for attackers to gain access to sensitive data using malicious code (e.g. infected downloads). You also need to protect yourself against physical loss in the hustle and bustle of the Christmas market.

How to protect yourself:

• Regular updates: Keep operating systems, apps and security software up to date. Security updates patch known vulnerabilities.
• Antivirus software: Install a reputable antivirus and anti-malware solution that can detect suspicious files or activity.
• Avoid public networks: Use a VPN on public Wi-Fi networks to encrypt your connection and protect your data.
• Keep an eye on your devices and lock them without exception when not in use.

Additional tips for businesses

• Raise staff awareness: Training on current threats and secure behaviour helps to protect the workforce.
• Network monitoring: Use monitoring tools to detect unusual activity in good time.
• Back-up strategies: Ensure that regular back-ups are created and checked to prevent data loss caused by ransomware.

Conclusion: Staying secure through the run-up to Christmas

Cybercriminals take advantage of the run-up to Christmas to capitalise on stress and the hustle and bustle. However, with the right measures in place, you can protect yourself effectively: be wary of social engineering tricks; regular backups; strong passwords; and secure devices form a solid foundation for security. This way, you can relax and enjoy the festive season – without any digital worries.
