iPhone security issues are not any different from that of other mobile devices

Implications: Any mobile device, in general, is a headache to corporate information security organizations. The security issues reported on iPhones are not  different from that on other smart phones or even (mobile) laptops getting connected to a corporate network.

Analysis: There has been a number of reports on iPhone's security issues much before the devices even came into the market. On top of that one of the recently reported "case study" on iPhone exploit added fuel to the fire. Is iPhone more of a security risk to the enterprises than other smart phones or mobile devices? Not necessarily. Any mobile device, in general, is a headache to corporate IT organizations. The security issues reported on iPhones are not  different from that on other smart phones or even (mobile) laptops getting connected to a corporate network. In fact, it can be argued that a mobile laptop is of a higher security threat to the enterprises than a mobile phone. This is because a laptop (with Windows family of OS/applications) is more open and an employee can, knowingly or unknowingly, download umpteen number of vulnerable applications when away from the corporate network. As smartphones (and other mobile endpoint devices) are less open - in the case of iPhone, it is fully closed - and available applications and hence chance of introducing vulnerabilities are limited. 

True that some of the built in applications like Safari browser on iPhones may be relatively more vulnerable (at least for now) than Internet Explorer or Firefox. But, coming from a "closed" system like iPhone, these threats are more manageable by the enterprises. [Apple is yet to support iPhones for enterprises, mostly because their focus currently is on the consumer side]. In the end, it is all about how well one manages the risk to the benefit -  whether those risks are the result of mobile laptops, Blackberrys or iPhones.
