The demand for these applications is driving development at a rapid pace. Unfortunately, the risks associated with mobile applications are different from typical enterprise software. Also, security is rarely a project driver in the mobile software world.
Business line managers need to make sure that marketing and IT managers who are building mobile applications are protecting of customer data and not inadvertently opening up unexpected security holes for outside attackers. Here are eight questions to ask them before proceeding.
1. How does the risk of software on mobile devices differ from that of enterprise software?
The very definition of mobile software is that it exists on a device outside your enterprise environment on the handset or tablet of an outside person, perhaps a customer. You can assume that the device will be jail broken and your source code reverse engineered. In addition, you will have little -- if any -- indication that someone is tinkering with your mobile application. Much of the attack prevention and detection will instead have to be based on examining how the mobile device interacts with internal servers.
2. How do these mobile apps interact with our internal servers?
Much of the media focus on mobile security is centered on the security of the device. In reality, most of risk may exist where the mobile device interacts with externally-facing servers. An organizations threat modeling and testing should reflect that reality. If the device can be jailbroken and the code reverse engineered, an attacker with modest skills can identify the target server that receives inbound requests from you mobile devices. At that point, the server has to be able to withstand the variety of application and network attacks.
3. Do we have the internal skill set to manage this risk?
Given the explosion of demand for iPhone, iPad, Android, and Blackberry applications, software developers with even modest experience are in high demand by enterprise leaders. Make a concerted effort to quantify your internal skillsets in mobile development or move quickly to pull in the small but growing community of mobile software security experts to help you lock down your mobile applications.
4. Are mobile code developers more or less likely than other developers to understand security concepts?
Unfortunately, for many the answer is "less," but certain high profile mobile code issues might be changing this. Much of the talent in this emerging market comes either from the interactive and creative world, the closed-system device development world. Neither are used to building "rugged" enterprise software that will withstand the rigors of Internet attacks. Furthermore, developers' unfamiliarity of mobile environments can lead to mistakes with security implications.
