Networking is a top skill. Three areas of focus for networking would be wireless, WANs and security. With so many mobile devices coming into the corporate world, in addition to the movement to cloud computing, this is a great space.
I suggest the following network classes and certificates: A CCNA certification (in routing/switching, wireless and security) would be more specific than Network+ admin classes and would give you more marketable skills. After that, I suggest you look into a CCNP, if you want to upgrade your network skills further, and a CISSP to round out your security knowledge and experience. Network and security roles are continuing to become more important in my organization. With Toyota Entune, most of our cars have amazing telematics features that require advanced networking services and hardened security. It takes very experienced individuals to provide these services.
I'm wondering whether a move into network support and administration would be a good hedge against outsourcing. I don't want to guess wrong, because I'll have to pay for my own training.
Generally, a company's outsourcing strategy is based on the unique needs of the organization. What I have noticed among my peers is that skills such as networking, data/business intelligence and security are, more often than not, locally sourced, but it would be difficult to predict what your experience will be. For whichever area you choose to focus on, my advice would be to spend time understanding the emerging technologies in that space and think creatively about how they can be applied to business. The ability to demonstrate this type of innovative thinking is highly valued.
