Data theft is the act of stealing computer-based information from an unknowing victim with the intent of compromising privacy or obtaining confidential information.
How data can be stolen.
There is more than one way to steal data. Some popular methods are listed below:
- E-commerce: You should make sure that your data is safe from prying eyes when you sell or buy things on the Web. Carelessness can lead to leaking your private account information.
- Password cracking: Intruders can access your machine and get valuable data if it is not password-protected or its password can be easily decoded (weak password).
- Eavesdropping: Data sent on insecure lines can be wiretapped and recorded. If no encryption mechanism is used, there is a good chance of losing your password and other private information to the eavesdropper.
- Laptop theft: Increasingly incidents of laptop theft from corporate firms occur with the valuable information stored in the laptop being sold to competitors. Carelessness and lack of laptop data encryption can lead to major losses for the firm.
How to Prevent it
- Regularly test the network to find and fix security weaknesses and investigate problems to find their cause, if they happen.
- Use passwords, and strong passwords to prevent unauthorised people from accessing the network.
- Enforce user access levels to limit the number of users with sensitive information.
- Install anti-malware and firewall software to prevent and destroy malicious attacks.
- Encrypt sensitive data.
