A recently released report from a survey of hundreds of executives and managers of infrastructure organizations (power grids, water treatment facilities, etc.) provides information that many of these information technology networks have been attacked, and that some have been adversely affected as the result.
This is potentially critical to our country's safety since we could be "shut down" with successful such attacks being focused, for example, on the electrical power grid across our country. Water systems could be compromised. Sewage treatment facilities could be made to dump untreated sewage...maybe that is what keeps happening in Milwaukee

... thus affecting the health and welfare of the people.
Many of these attacks that have already occurred are believed to have been launched by foreign countries.
Such attacks can include the implanting of malicious software that can be triggered at will by the person or organization that planted it. Some are the classic "denials-of service" attacks where a system is simply overwhelmed by huge amounts of Internet traffic aimed at the servers.
These issues need our country's immediate and serious focus to preclude us being taken out without a shot being fired. One wonders if this could be the "nuclear weapon" of this generation.
We, as a country, have not paid the kind of attention we should have been paying to the education of technology minds. We may find ourselves in the class of "have not" countries in this regard if we do not do something about this imbalance and very quickly. Our education system needs reforming and it needs that reform very, very soon. Even with that, we will have slipped several generations behind this dangerous new curve.
