"Only one instance of attempted hacking on computers belonging to defence sector has come to notice in the past three years. There were intelligence reports in November 2011 about the probable compromise of computers of Eastern Naval Command based in Visakhapatnam," Defence Minister A K Antony said in a written reply.
"However, none of these computers was found to be compromised.
The defence services have a robust defensive mechanism in place," he said.
For protecting critical information infrastructure, he said, "Section 70-A of the Information Technology (Amendment) Act 2008, envisages setting up a National Critical Information Infrastructure Protection Centre (NCIIPC) for protecting critical information infrastructure in identified sectors."
Steps have been initiated for notifying NCIIPC under the said Act, he said. AD
