can u please make it so i can use it in lower forge versions like 14.23.4.2758

No, sorry. SecurityCraft uses features of Forge that only exist in newer versions than 14.23.4.2758. You either have to just try updating the Forge version that you are using (usually that shouldn't be a problem unless the mod specifically limits the Forge versions it can be used on) and update/remove incompatible mods along the way (if an update is available of course), or downgrade SecurityCraft to a version that works with Forge 14.23.4.2758 (which I believe should be SecurityCraft v1.8.14.1).
