Data Security & Information Risk Management
Encryption
Data encryption has become an unfortunate necessity for responsible data managers, and is increasingly used to protect digitally held information; from personal details held on a computer to medical details transmitted over a LAN, WAN or the Internet. Wherever sensitive, personal or identifiable data is stored measures must be taken to protect it from loss, whether malicious or accidental, destruction and/or damage.
Encryption is the process of converting information into an encrypted form, so that it is intelligible only to someone who knows how to ‘un encrypt’ it to obtain the original message It is commonly used in connection with electronic data, whether stored on a computer or transmitted over an unsecured network such as the Internet. Encryption tools are widely available and can be used to secure:
- Stored data, from single files and folders to entire hard disks.
- Data transmissions including emails and internet telephony.
- Network infrastructures, such as wireless networks.
The security of encrypted data depends primarily on the choice of algorithm and key length. For example, personal details stored on a medical database would require protection by a strong algorithm and a long key that would be very difficult to break.
Algorithm strength is often described by the bit length of its encryption key. The more bits in the key, the harder it is to decrypt data simply by trying all possible keys, both Connecting for Health and The Cabinet Office recommends software solutions with algorithms operating using 256 BIT.
Data Leakage Prevention
Enterprise endpoints – desktop and laptops – have been swamped with new connectivity options. WiFi, Bluetooth, IrDA, Wireless, USB, and others are all exciting new productivity innovations that create fast, hassle-free connections between desktops and devices. But, they also multiply the ways that sensitive data can leak from the organization.
Organisations are increasingly turning to solutions to detect and enforce restriction of devices. Security administrators are particularly concerned with storage devices and are increasingly regulated to either:
- block all storage devices completely
- permit read-only
- encrypt all data on devices
as well as monitoring, blocking and logging files that are downloaded to or read from these devices.
Trustmarque Solutions recognises the risks faced by organisations and has partnerships with global security manufacturers to provide solutions to protect access the latest threats to data loss, misuse and malicious activity.
