*Computers simply being networked is not a sufficient condition to allow foreign interference - why would any of the systems [[Felix Gaeta|Gaeta]] links be connected to [[wireless]] channels? Is the infiltration that he detects originating from within ''Galactica''? | *Computers simply being networked is not a sufficient condition to allow foreign interference - why would any of the systems [[Felix Gaeta|Gaeta]] links be connected to [[wireless]] channels?

**As with any other Colonial ship, ''Galactica'' receives data all the time from exterior sources. In addition to its mainframe computer, ''Galactica'' primary computers include the FTL, Navigation, Damage Control, and Fire Control systems. The mainframe ostensibly handles wireless communications (Note [[Sharon Valerii|Caprica-Valerii]]'s request for access to the mainframe with its communications channels in "[[Flight of the Phoenix]]"). The mainframe probably ''did'' come under attack by the Cylon virus but was able to avoid infection because a Colonial mainframe may have been what the Colonials believed would be the central lynchpin in stopping any Cylon computer cracking. | **As with any other Colonial ship, ''Galactica'' receives data all the time from exterior sources.

**While the Colonial Fleet became lax in their computer defenses years after the [[Cylon War]], they probably believed that a networked computer system would be acceptable provided that their battlestar's mainframe computer or a robust avionics package and programming would be able to block or stop any electronic incursion. That fact might have been true—were it not for the [[Command Navigation Program]], which gave the Cylons a backdoor to any Colonial flight computer system.

That fact might have been true—were it not for the [[Command Navigation Program]], which gave the Cylons a backdoor to any Colonial flight computer system. Instead of ramming the main door (mainframe) down, the Cylons used the "window", entering through a lesser computer (or opening a hole in their network) to achieve the same effect. The CNP helped to bypass the defenses of the mainframe, where normal communications were probably screened and electronic attacks thwarted, to enter through another system. | ||
**''Galactica'''s computers may have never been networked in her history before this episode. Her computers may also not be as robust as her sister battlestars. But her computers were designed to be networked or run separately since Gaeta was able to set up a network at all. It was very likely that the mainframe was part of Gaeta's ad hoc network since the other computers would not be able to gather any data from the mainframe's wireless communications. Once the connections were made, the other computers (all of which probably had less resistance or defenses to Cylon viruses) were likely more susceptible to infection than the mainframe as these computers could now "hear" the same things that the mainframe heard normally in its business (such as Cylon electronic attack sequences), but was far more able to thwart. The lesser computers became infected quickly. After a time, even the mainframe in whole or in part would be infected since the Cylon virus is remarkably adaptable and polymorphic, even turning later into a [[Logic bomb]] after learning and probing ''Galactica''{{'|s}} hardware (in "[[Flight of the Phoenix]]"). | **''Galactica'''s computers may have never been networked in her history before this episode.
