How to Protect Personal Data to Keep It Safe from Hackers in the Digital Era

In this connected era, personal data is a very valuable asset. Unfortunately, along with ease of internet access, the threat of cyber crime such as hacking and identity theft is also increasing. Without proper protection, your sensitive data can be misused by irresponsible parties.

The following is a practical and effective guide to keeping your data safe from the reach of hackers.

1. Use a Strong and Unique Password

The most common mistake that users often make is using the same password for all accounts. If one account is successfully penetrated, then all other accounts will also be threatened.

• Complicated combinations: Use a combination of uppercase letters, lowercase letters, numbers, and symbols.
• Avoid personal data: Do not use dates of birth, names of family members, or telephone numbers.
• Use a Password Manager: Applications like Bitwarden or LastPass are very helpful in storing hundreds of different passwords securely.

2. Enable the Two-Step Verification (2FA) Feature

Two-Factor Authentication (2FA) is the second layer of defense after passwords. Even if hackers manage to find out your password, they still can't log in without a verification code sent to your device.

3. Beware of Phishing Mode

Hackers often use phishing methods to trick you into voluntarily providing personal information. They usually send messages via email, SMS or WhatsApp posing as official parties such as banks or application companies.

Characteristics of Phishing Messages:

• Using an urgent or threatening tone.
• Sending links that look strange or unofficial.
• Request a password or OTP code directly.

4. Pay Attention to Wi-Fi Network Security

Avoid making financial transactions or logging into important accounts while connected to public Wi-Fi in cafes, airports or other public places. Public networks are very easy to hack by hackers who are on the same network.
