You can't really avoid it, especially if you work in a big corp. It can happen absolutely regardless of what you do - somebody could decide the whole section is redundant, or they're getting out of this business, or they just need to reduce the workforce and you got the short straw. It'd suck if it would happen, but it's better to realize it's a possibility and be ready. I don't mean to work with one foot constantly out of the door, people don't like that, but have a plan just in case - just like people have plans for natural disasters, etc. Keep your knowledge fresh and broader than your current job, take interest in new stuff that may help you find your next job, network with people that may not be connected to your current job but may very well help you find the next one. Maybe you'll be lucky and will work at this job until you're sick of it and ready to leave or retire. Or maybe not - be ready for it.
