I have raised questions, and will do so in the future as well, whose answers I do not expect to receive. Because, the competent people who can answer them should either not be posting on this forum, or should not be talking publicly on the topic. We need a level of intellectual maturity as a nation to realize that some topics can be pointed out, but left out from further discussion. This is the reason I have previously requested the ability to create locked threads to which no one else can post.The man will have no interest in jeopardizing his career and the firm in jeopardizing their reputation for releasing their clients opsec.
These fears are unfounded and based upon bias and hearsay. If it is going to be compromised then it would be from manufacturing nation and not the individual sitting as CIO.
To answer your points, this guy doesn't need to do anything illegal to harm Pakistan's interests. As part of his move to Amazon cloud, he simply needs to plan for disaster recovery scenarios by geographically replicating data. Now assuming Viasat holds information related to Pakistan's national security, this information can end up physically in some data centre in India. Meanwhile, being the good American that he is, and given the laws around data security in US and Europe, he will conveniently ensure that sensitive US data stays within the US, sensitive European data stays within Europe, etc.
As long as you depend on foreign companies for elements of your national security, your sensitive information will be similarly dealt. Pakistan has no financial, political, or legal leverage over Western suppliers. If people in important positions are not losing sleep over this, then they are incompetent and this doesn't bode very well for the country.
It should be noted that once data is stored physically in an Indian data centre, it should be considered compromised even if it is encrypted. If the system is using local encryption keys, then the data will be unencrypted locally before transmission, thus it is compromised. But even if encryption keys are stored remotely, India has the means and connections to put professional cryptanalysts on breaking the codes.
Finally, there is the matter of Viasat having two R&D centres in India. Future mandatory updated to our F-16 may very well be developed in India. A very disconcerting state of affairs, indeed.
