It is very likely that in any survival scenario Guard Duty or "Fire watch" would be a big priority, especially while you are getting established.
Create a "Guard" order for the colonists (like mine, except it doesn't wear off).
Create a Guard task in the overview (i'd say place it just before hauling in the priorities list).
Then you would just click the Guard order on a tile to turn it into a Guard Post.
If a colonist has the Guard task turned on, he/she will take up that selected post until another task of higher priority presents itself. Any colonist that is guarding will automatically shoot hostiles within their range, or if melee set a base melee engage range (and have them return to their post after the threat is gone).
To go even further and make it more complicated, you could have characters with Warden task turned on actually bring food out to characters that are guarding. Guards that fall asleep could fall victim to kidnapping. Guards that spend too much time Gaurding get moody or turn homicidal.
