They don't even secure their network traffic from an enemy who regularly uses electronic warfare tactics.
That doesn't strike you as a tad odd for someone thats been going at this for so much longer?
live and learn, first time for everything.
how long did it take for humans to decipher their language were others offered the time and opportunity.... doubtful?
if their is one thing the Covenant have demonstrated it's loyalty and focus and not opportunism..... humans chase the mighty buck anyway they can and at the expense of all others, Covenant strive to save themselves from a doomed existence, right or wrong purity of purpose and while they may compete the end goal is the same.
the reality that they began to guard against intrusions indicates they do know their technology and they know how to adapt it to suit..... this is a concept overlooked by the book series as it try's to hang onto the idea that the Covenant are too stupid to change all the while the author demonstrates that they can and do all the time....... it's one of many reasons why the Halo books suck so badly.
The covenant seem just as unbalanced as us when it comes to religion and affairs of state.
irrelavent, what would matter in affairs of state is stability which the Covenant have shown with the prophet caste in charge throughout and if the prophets were in control throughout then they would have a huge advantage over mankind born from a society of broken nations all striving to keep their own secrets from anyone else in a race for dominance that was likely achieved in Covenant society far earlier.
What I suspect is this prophet race (with forerunner bits) posed themselves as a messiah to the big blue fanatics and together both races went about dominating all the surrounding star systems.
in order to meet a new species they would have to travel space meaning they had to build, meaning they had to be intelligent, meaning they not only had to create but had to apply and innovate.... additionally it's not all about the Elites as demonstrated by the inclusion of the Brutes..... even if the prophets stumbled across forerunner technology one still has to learn how to use it and apply it to practical purposes.
the Covenant has their own distinct technology differing entirely from forerunner tech from weapons to ships and add to that their extensive knowledge of forerunner tech.
mankind had the "dark ages" stifling 800 years of advancement for the sake of control.... additionally mankind evolved in a society where it was all about the individual, the individual nation, the individual leader in the Halo storyline it wasn't until the Covenant showed that it became a fight for survival of the species...... and while makind screwed the pooch for 800 years along with another 1000 of self indulgence they did advance only slower..... to the tune of being 300 years behind the covenant..... like it or not that is where Halo begins with mankind 300 years behind.... and it would explain why mankind can't sort out Covenant tech considering I doubt any scientist from the 1700's could figure out how to program a computer let alone build for example an E6600 conroe processor.
