Likely more secure positions will be network engineers or security engineers. Which way to go depends on your current income level. If you are deep into your career and earning a high income you are better off with the security path. Security engineers cap much lower than top network engineers, but pay well starting out. For security study up and take the CISSP test.
Network engineering will kind of feel liking starting over in your career. You will want to start with an entry level certification like the CCENT and work towards the beginner CCNA certification. Years later once you can pass the CCNP certification you might well be making more in networking than in software. Then if you stick around long enough to become an expert you can attain a CCIE which provides excellent job security at high pay, especially if you have extensive software scripting experience.
