Special Report: Marketplace Security Survey, Risky Business - 36

MAINFRAME SECURITY SURVEY from outside threats. Monitoring cloud security infrastructure was a concern for 57.2 percent. Others included maintaining regulatory compliance (48.8 percent), monitoring workloads across multiple cloud infrastructures (34.7 percent) and monitoring cloud-based network data traffic patterns (29.4 percent). See the results in Figure 3 on page 38. "One of the things people are doing to mitigate risk is leveraging hybrid clouds," Sardino says. "They may have application components in this environment or use software as a service that connects securely back to the system of record. This allows you to have a layered approach to security with sensitive data residing on the mainframe and other, less sensitive data and applications on the cloud." According to Shay, mainframe cloud is generally just as secure as non-cloud, mainframebased resources. Cloud-based mainframe data typically resides in a secure data center, leaving the data center on secure lines or a VPN, much as non-cloud data runs through secure networks within home data centers. As far as he's concerned, "security concerns for mainframe clouds are exactly the same as non-cloud implementations." Removing Barriers Many organizations have similar concerns about mobile Figure 2: Which one of the following best describes your company's industry? computing. Among their reservations, according to the survey, are data privacy (74.9 percent), access control (64.2 percent), mobile device loss or theft (50.7 percent), third-party mobile apps (43.1 percent) and compliance (32.7 percent). "It would just kill me if I lost my phone and all of the personal data I have on it was misused, but that's just the tip of the iceberg," King notes. "Take a car rental agency, for example. It might use tablets in the field when checking cars in and out, and those devices likely have access to a lot of back-end data, such as personal customer data and credit card numbers. If someone gets ahold of those devices, he can do more damage than you know." "You can't just get a certificate and automatically call yourself an expert. It takes years and years of experience to get to that level." -Stan King, CTO, Information Technology Co. 36 // SEPTEMBER/OCTOBER 2016 ibmsystemsmag.com Shay sees mobile devices as just another method to access the mainframe. Already, capabilities exist to provide secure access for authorized users with a smartphone or tablet. "You just need to do your homework," he adds. Encryption is one way to address concerns regarding both cloud and mobile. The majority of survey respondents report having some type of encryption in place, for a total of 71.4 percent (33.6 percent symmetric and 37.8 percent asymmetric). However, 28.7 percent have no encryption technologies in place. This is a startling number, given the built-in encryption capabilities of z Systems, both at the hardware and z/OS* levels. Part of this could be due to perceived complexities or uncertainty about what to encrypt. The general consensus regarding the latter is to perform an inventory of what's most sensitive and encrypt that, both at rest and when it's in motion. In some cases, organizations are concerned they might have to rewrite applications to allow for encryption. Some tools-such as http://www.ibmsystemsmag.com
