Security, disaster recovery and data encryption continue to be topics on every CIO and IT person's lips nowadays. No one wants to end up in the news as the next victim of a privacy breach or the next company that did not protect its customers information. If you conduct a news search using the words personal data breach, you will be alarmed at the number of instances where personal information such as social security and credit-card numbers have been exposed to possible theft. In a recent breach, a state government site allowed access to hundreds of thousands of records, including names, addresses, social security numbers and documents with signatures.
Whether it is government agencies, research facilities, banking institutions, credit card processing companies, hospitals or your company's computers - the risk of compromising private information is very high -- especially when when conducting a disaster recovery tests. Since business relies so heavily on technology today, business risk becomes technology dependent. The possibility of litigation is part of business. It has always been a risk of doing business, but because technology and today's business are so intertwined, business risk has a higher threat level. This has prompted many to encrypt workstations and mobile computers in order to protect critical business data
If you have rolled out encryption, how do you maintain your IT service quality when the hard disk drive fails? How do you plan and prepare for a data loss when the user's computer is encrypted? These are all issues that should be considered when putting together a data disaster plan. In addition, data recovery, one of the more common missing elements of a disaster recovery plan, should also be factored in because it can serve as the last ditch solution when all other options have been exhausted.
Data Recovery and Encryption
Business continuity and disaster planning are critical for businesses regardless of their size. Most archive and backup software have key features to restore user files, database stores and point in time snap-shots of users files. Software is becoming more automated so users don't have to manually backup their files. Some computer manufacturers have built-in backup systems that include dedicated hard disk drives for archive storage. Most external USB hard disk drives have some sort of third party software that provides data archiving during a trial time period. Such solutions, while solving the data backup need, create questions regarding how effective the systems are with respect to user data. What are your options when a user's computer has a data disaster and the hard disk drive is fully encrypted?
Most IT security policies require a multi-pronged approach to data security. For example, when setting up a new computer for a user, the IT department will require a BIOS (Basic Input/Output System) password for the system before the computer will start. BIOS password security varies in functionality. Some are computer system specific, meaning that the computer will not start without the proper password. Other BIOS passwords are hard disk drive specific, meaning that the hard drive will not be accessible without the proper password. Some computer BIOS employ one password for access control to the system and the hard disk drive. To add a second level of protection, new IT security policies require full hard disk drive encryption. The most common of full hard disk encryption software operates as a memory resident program. When the computer starts up, the encryption software is loaded before the operating system starts and a pass-phrase or password prompt is required. After a successful login from the user, the software decrypts the hard disk drive sectors in memory, as they are needed. The process is reversed when writing to the hard disk drive. This leaves the hard disk drive in a constant state of encryption. The operating system and program applications function normally, without having to be aware of any encryption software.
