In the original game, when the aliens start attacking your base, they keep coming until you let them in and defeat them in tactical combat. Once you do this, they have to find your base again.
But here's the thing - lots of different "groups" of aliens can find your base, and the more that do, the more attacks come in.
This would imply that there are different "factions" of aliens and they don't share all their knowledge with each other. It could be that this is done on a "per alien race" basis, though I suspect it's more of a "per alien base" thing.
Probably just a game mechanic, but still an interesting thought.
But in terms of realism, race seems the way to go: Each is "competing" with all the others, and so if you take a base down, only that race knows about it (kinda like how not all humans know where X-COM bases are - it's not like the military comes to your aid when you need it). They're not going to alert the other aliens to their little problem, for fear of one of them taking instead of returning the lost outpost. Hence they may be somewhat lacking in terms of the resources required to immediately attempt to evict you.
The thing with this is that it MAJORLY impacts the in-game lore. Before implementing something like that, there would have to be a bit of discussion on how the alien society actually works, and how the different races interact.
Hell, that's worth at least one thread of its own.
Heh, I suppose I'm going off into dreamland with this next idea, but it seems to me it'd be pretty cool if you could capture an alien base without any of them knowing about it - that is to say, you could maintain a front that it was still under alien control, steal off their supply ships, and perhaps even get access to secret transmissions that wouldn't be picked up any other way.
SB1: This is Sectoid Base One! We are under attack, repeat, we are under attack!
CC: Cydonia Command here. Identify the nature of your attackers and the scope of the assault, and we'll have reinforcements on the way as soon as feasible.
SB1: It's...we can't...its X-co-....
CC: Sectoid Base 1? Sectoid Base 1, come in! Sectoid Base One?
SB1: *cough* Haha, hi there, glorious and all-destroying supreme commanders. This is...um...*what are they called again? Oh, right* the Sectoid base. Y'know, Sectoids. We're short and have big heads. How you doing over there, your evilness?
SB1: Anyway...uh...sorry to bother your vileness, but...uh...we need some more supplies. Like, if you could send us a few shipments of elerium, crewed by floaters or snakemen (but no chryssalids), it would make crushing the puny hu-mons much easier. You might as well spare the expense of arming them too; we have things under control pretty well here, there shouldn't be any danger.
