Star Trek

Like even Cruise liners today and Cruise ships have there bridges and engine rooms and crew quaters all seperate from passengers and secure only they can get in there unless off course a passenger forced there way in or maybe threatened the ship .

So should vessels like Enterprise and Voyeger not have had the same security or  better even .

An Example is in  "The Neatral Zone " episode in the next gen the reporn musician that Data saved from the old 20th century vessel goes into the Turbo lift and goes up and unto the bridge while they are trying to make contact with the Romulans .  

Yeah, you really need to wonder why Picard didn't see the stock-broker's point - The honor system isn't working real well for ships of The Federation.  I suppose you could understand in the first few TNG seasons where everyone is blissfully ignorant that anyone wants to do them harm (see: Pre-9.11 America), but later seasons have no excuse.

I have to agree, certain decks should have required a clearence of some sort.

Clearly the computer was capable of recognizing voices and it would only need apply to civilians and visiting guests.

That always bothered me I always figured it was an open society. Although I knew that the writers had only an hour per episode and had move the story along so having an open door policy worked. Look at Charlie X would he have destroyed the ship if he hadn’t been allowed on the bridge. 

In the military, all secure locations have mutiple layers of security (including armed guards.)  I'd think that Engineering & the Bridge would be the #1 secure locations in the ship.

I'm not for armed guards around key areas except maybe during the war and red alert.  I do believe that the computer should know if an individual has deck 1 or engineering access before taking the turbolift or openning a door to those locations.  Maybe treat their comm badge as an access badge.

I know that the animated series isn't canon, but, in the ep ''Beyond the Farthest Star'', at least in the written version I read a good long time back in my ST:TAS Alan Dean Foster books, the bridge has a defense system, in the form of a phaser dome in the center ceiling.....If you'll recall, there was a crewman on Pike's Enterprise in ''The Cage'' stationed at the lift alcove; Was he a security person, or, perhaps he was some sort of 'runner', who knows, at beckon call of the captain, or some specific duty situation,  perhaps as replacement in a pinch?? I remember in a TOS novel, LOL, the older Commodore Jose Tyler on a visit to the refitted 1701 remarks with a chuckle about the guy, named 'Valdini, I think', and couldn't remember what the heck the guy was there for....For purposes of tv itself, though, having some type of passcode to enter the bridge would interrupt the action, particularly in a very fast-moving series of events. Imagine Kirk, having to key himself in, just before the next scene shows him stepping onto the deck, to find, to his shock-and we viewers' excitement, the drama of a massive alien ship hovering over a dwarfed Enterprise....BUT, yes, given the criticality of the need, in a real-world 'trek' to the stars, in a far from empty universe, the practice of safeguards would be sound....

I completely agree.

I know the feeling, but when we installed a new automated security system, we were able to cut the number of guards down, though we didn't eliminate them entirely.  Most of the access gates could be left alone at that point, but critical areas still needed people standing by.

Starfleet wouldn't really need much to secure its ships, especially on ships like The Connie Enterprise or Voyager, since they are all Starfleet personel.  A guard around the core and on the bridge and some little security scanners should be plenty.  However, The Ent-D should have had much greater security due to the large number of civilians and passangers the ship carried.  There really is no excuse for an "honor system" security policy, especially when they even specifically mention how great their honor system policy is!

This is because the Federation is made up of incompetance.

They can slingshot around the sun to travel back in time and replicate food and materials as necessary. Surely an open, unsecure bridge is low on the realism gripe scale.
