1. Create Fortresses with Passwords: Strong and Unique
Imagine your password as the door lock of your digital home. The stronger the lock, the more difficult it will be to break into. Therefore, it is crucial that your passwords are:
- Long: Minimum 12 characters, and the longer, the better.
- Complex: Use a combination of uppercase and lowercase letters, numbers, and special symbols (!@#$%^&*).
- Unique: Each account should have a different password. Avoid using the same password for multiple services.
Additional tips:
- Don’t use obvious terms like your pet’s date of birth or name.
- Change your passwords regularly, at least every 3 months.
- Use a password manager to help you generate and store strong passwords.
2. Beware of Phishing: Don’t Get Hooked
Phishing is a technique in which hackers impersonate trusted institutions (e.g., banks, authorities) and try to extort sensitive information from you, such as logins, passwords, or credit card details.
How to recognize phishing?
- Suspicious links and attachments: Don’t click on links or open attachments in emails from unknown senders.
- Spelling and grammar mistakes: Pay attention to the language of the message. Hackers often make mistakes.
- Requests for sensitive information: No reliable institution will ask you for your password or credit card details via email.
Remember: Always check the sender’s address and website address before entering any data. If in doubt, contact the institution by phone.
3. Keep your software up to date: Secure your systems
Software updates are not only new features, but above all security patches that protect your computer and phone from hackers exploiting vulnerabilities.
Therefore, it is important to:
- Update your operating system regularly: Windows, macOS, Android, iOS.
- Update your web browser: Chrome, Firefox, Edge.
- Update your antivirus software: Make sure you have an antivirus installed and update it regularly.
4. Use a VPN: Encrypt Your Online Traffic
A VPN (Virtual Private Network) is a service that encrypts your internet traffic and masks your IP address. This ensures that your data is protected from interception by third parties, especially when you use public Wi-Fi networks.
When should you use a VPN?
- In cafes, hotels and other public places: Public Wi-Fi networks are often unsecured, making it easy for hackers to access your data.
- When traveling: A VPN protects your privacy and allows you to bypass censorship in certain countries.
- When using online banking and other sensitive services: A VPN adds an extra layer of security.
5. Beware of Social Media: Protect Your Privacy
Social media is a treasure trove of information for hackers. Be careful about what you post and what information you share publicly.
A few tips:
- Restrict access to your profiles: Privacy settings let you control who can see your posts and information.
- Don’t share sensitive data: Avoid posting your address, phone number, or credit card information.
- Beware of fake profiles and contests: Hackers often create fake profiles and run contests to trick users out of their data.
6. Educate Yourself and Others: Knowledge is Power
The more you know about cybersecurity, the better you can protect yourself.
Here are some sources of information:
- Websites dedicated to cybersecurity: e.g. CERT Polska, Niebezpiecznik.
- Blogs and articles on security: Many websites publish articles and guides on cybersecurity.
- Trainings and workshops: You can take part in training courses that will help you expand your knowledge and skills in the field of cybersecurity.
Remember that cybersecurity is an ongoing process. Hackers are constantly improving their methods, so it’s important to stay up-to-date on the latest threats and follow security rules.
