Before each mission I plan out the security of the locations are you likely to hit. The amount of planning can vary drastically, if it is a club or other location that is primarily designed as a role play encounter it will not be carefully spec'd out.
If it is a location I expect to be a combat encounter, I will most likely stat out the basic dimensions and various obstacles and cover available.
Lastly, if it is a location which I expect some sort of infiltration attempt to be made, it will be carefully spec'd out in advance. The security features will all be written down and spec'd out.
If I overlook some sort of security feature on creation that the players choose to exploit then they successfully exploit it. The players will NOT be violating "Rule Zero" on that mission. I am not going to modify the security because they mention (or plan for) a specific feature. Additionally I am not going to modify security because they are not skilled in dealing with a specific feature.
After a run on a given location, the security MAY be modified for future missions. It takes time, but locations can retrain security and add new features.
WMC's primary housing facility has fairly solid security. During a rather noisy run on the location it was shown that their weak point was employee training and the front gate. Next time runners pay this location a visit, they should expect both these defenses to be improved.
