IBM Tivoli Key Lifecycle Manager solves security problems and meets new standards


Now organizations realize tapes aren’t the only potential data leaks. Disk drives and even photocopiers store old data and eventually leave the data center, risking exposure. “Photocopiers actually keep copies of the last n-number of photocopies it’s made,” Arnold says. “So people have gone out and bought disk drives out of photocopiers and discovered all sorts of sensitive information.”

Disk drives leave data centers all of the time, according to Arnold. They go out of lease or need repair and “about 90 percent of disk drives that go out for repair still have readable customer data on them,” Arnold says. Even with stripping and raiding the data, block sizes can be large, and they’re getting larger. “Even with an average block size of 4 K, you can get a lot of credit-card numbers or Social-Security numbers in that large of a block. That’s an audit and compliance exposure; it would trigger the disclosure requirements that are now in 45 U.S. states,” Arnold says.

The Problem With Keys

A major reason for avoiding encryption implementation is fear of losing the keys needed to decrypt the data. Even administrators who have experience with good key-management systems for encryption and who believe key loss can be prevented often have concerns about complexity, interoperability, performance and cost. Additionally, administrators must decide whether to encrypt data at rest, in flight or both. And there’s the performance hit data centers can experience with encryption, slowing daily operations.

Implementing encryption and key management can help organizations reduce risks, address audit deficiencies, simplify the repurposing of disk drives and entire systems, as well as maintain continuous, reliable access to information. “The good news is we can do all this with no performance penalties and at very low cost with TKLM,” Arnold says.
