EMC Corp.’s recent acquisition of RSA Inc. underscores the convergence of information security and storage. EMC, which sells large storage systems for use in corporate data centers, bought RSA—a manufacturer of encryption software and devices—to provide it with identity and access management technologies and encryption and key management software, which will help EMC deliver information lifecycle management. A survey last year by CompTIA, an IT trade association, found that protecting and securing data is the number one challenge in storage management. Security was cited as the top concern by one-third of storage management execs surveyed; management and administration of stored data was the second highest concern, followed by speed of access to stored data, and making data more accessible.
