Encryption

Encryption is where information is scrambled in such a way that only those with the appropriate access can unscramble that data to read it. Encryption therefore provides protection for sensitive data.

Due to their portable nature mobile devices, such as laptops and smartphones, are more likely to be lost or stolen. While the cost of the mobile device itself may not be high the value of the data held on the device could be quite high. Many modern operating systems have encryption features built into them, which SMEs should enable to ensure the data stored on mobile devices are encrypted.

For data that is transferred over public networks, such as hotel or airport WiFi networks, or over the Internet, SMEs should ensure that data is encrypted, either by employing a Virtual Private Network (VPN) from a trusted provider or accessing websites over secure connections using SSL/TLS protocol.

Similarly, for their own websites, especially if that site is being used to support online transactions, SMEs should ensure they are employing suitable encryption technology to protect client data as it travels between the SME’s server and the clients’ devices.
