Can Stuxnet be detected?
Stuxnet is very difficult to detect. Most of the traditional security best practices cannot prevent or cannot guarantee the detection of Stuxnet [17]. Because Stuxnet used four zero-day vulnerabilities, having an up to date and fully patched system could not provide defense against Stuxnet.
How was Stuxnet tested?
Stuxnet would check the system it was on to ensure that it was a gas centrifuge controller in the Natanz facility, run modules in its code to check the current settings and time on the device, decide if the settings and conditions were appropriate for an attack, and if everything matched perfectly it would spin the …

What kind of software does Stuxnet infect?
Stuxnet infects the PLC programming software on a PC; it can both inject malicious code into the PLC and hide the malicious code from a user who attempts to view the PLC software. Stuxnet has 70 encrypted code blocks for both foundation routines such as file operations as well as custom code and data.
How can I protect my network from Stuxnet?
Two important practices that might have helped protect against Stuxnet are virus scanning (or banning) of all USB sticks and other portable media, and endpoint security software to intercept malware before it can travel over the network. Other practices for protecting industrial networks against attacks include the following:
What kind of vulnerability does Stuxnet exploit?
Early versions of Stuxnet exploited a vulnerability in the processing of autorun.inf files; it added commands that the user could inadvertently select, causing Stuxnet to be installed on the host machine. More recent versions used a vulnerability that allowed automatic execution while viewing a removable drive.
