NASA Stepped Up Security Measures Shortly After 9/11 Terrorist Attacks, Russian Cosmonaut Says
"The first conclusions from the situation were drawn very quickly, in the very first days. The Johnson Space Center is located far from the places of the terrorist attacks. Everyone there knew each other, and there were no outsiders. Nevertheless, the security service immediately introduced new questionnaires and obligated all Johnson Centre employees to fill them out, including the Russian delegation. They demanded that everyone update passwords on their computers, making them principally new, more complex and long. Security measures had been implemented for several months in a row," Yurchikhin said.
