What are the risks of unencrypted data transmission over the internet?

Unencrypted data transmission over the internet risks data interception, manipulation, and theft by unauthorised parties.

When data is transmitted over the internet without encryption, it is like sending a postcard through the mail. Anyone who intercepts it can read its contents easily. This is a significant risk as the data could contain sensitive information such as personal details, financial information, or confidential business data. If this information falls into the wrong hands, it could lead to identity theft, financial loss, or business disruption.

Moreover, unencrypted data is vulnerable to manipulation. Cybercriminals could alter the data during transmission, changing its content or meaning. This could lead to misinformation, miscommunication, or even fraud. For instance, if a bank transaction is not encrypted, a hacker could potentially alter the amount or the recipient's account number.

Another risk is the potential for data theft. Unencrypted data can be copied without leaving any trace, allowing cybercriminals to steal information without the sender or recipient even realising it. This could lead to significant losses, especially if the stolen data is sold or used for malicious purposes.

Furthermore, unencrypted data transmission can also lead to compliance issues. Many regulations, such as the General Data Protection Regulation (GDPR) in the European Union, require certain types of data to be encrypted during transmission. Failure to comply with these regulations can result in hefty fines and damage to a company's reputation.

In summary, unencrypted data transmission over the internet exposes the data to a variety of risks, including interception, manipulation, theft, and compliance issues. Therefore, it is crucial to use encryption to protect data during transmission, especially when dealing with sensitive information.
