1Storing Business Data on Personal Devices: Eight Things Enterprises Must Know
2There Is No Perimeter Anymore
With the convergence of personal and business devices, there is no “inside” or “outside” any longer. Web-facing applications provide direct access to ERP systems, and these vulnerabilities expose internal systems to cyber-criminals. A recent example is the Kneber Botnet, a massive botnet that affected some 75,000 computers at 2,500 companies and government agencies worldwide during 2008 and 2009. Kneber was used to gather log-in credentials to online financial systems, social networking sites and e-mail systems for about 18 months.??Ã
3Personal Devices Pose a Serious Threat
The portability, connectivity and storage capacity of cell phones, MP3 players, USB flash drives, iPads and many other devices pose security risks. Risks include data leakage/theft and malware; because of several gigabytes of storage capacity, the devices can capture/store massive amounts of sensitive data (for good or bad); and the fact that they are far too easily lost or stolen.
4Cloud Computing Complicates Security Controls
There are no walls, and the risks are concentrated. Few people realize that DBAs have open access to all data within a cloud. Separation of duties is needed; privileged users need to be monitored in real time. Cyber-criminals can get fast access to information using SQL injection; enterprises need to monitor access to sensitive data in real time.
5Virtual Is Now Reality
Increased desktop virtualization on personal devices circumvents traditional defenses. A recent industry study reported that 85 percent of more than 300 IT professionals said they have virtualized at least some of their servers. However, only 28 percent of respondents expressed confidence that their virtual environment is as secure as the rest of their IT architecture. A full 65 percent of respondents indicated they have not implemented a separation of duties policy between the staffers responsible for provisioning virtual machines and other administrator groups. Lost and stolen devices with access to virtualized systems pose a serious threat.
6Compliance Does Not Protect You
Simply being current with federal and local data storage regulations does not affect how airtight a system’s data protection may be. Storage regulations, such as HIPAA and Sarbanes-Oxley, spell out what should be stored, how it should be stored and for how long, and some basic security requirements. But hackers have always been a jump ahead of the security providers, and even very recent compliance rules can be outdated in a short time.
7Forget About Firewalls
8Encryption Is Essential
9Enterprises Need a Layered Defense
Enterprise security should include layers in the data center that monitor access to ERP systems and the database. Administrators should always be on the lookout for unauthorized or anomalous activity.
