Talking to reporters at Defexpo 2014 here, Chander said that leakage of information could take place in a subverted system, adding that there was need to get exposure to the internal processes when acquiring a new system.
“Today cyber security is our biggest security challenge…. This requires new paradigm in purchase processes. When we buy, we must buy with security in mind,” Chander said.
Earlier, Chander said at a press conference that the Defence Research and Development Organisation has launched a major programme for developing cyber technology tools and a lot of work was being done in that direction.
He said real cyber security could be ensured by taking adequate safety measures from the time software is developed.
“If real security (is to be ensured), answer lies (in getting involved) from the design stage,” he said, and added that it was difficult to do so in systems that were procured from outside the country.
“Wherever equipment is being bought (from outside the country), you have no control,” he said.
Chander, who is also scientific advisor to Defence Minister A. K. Antony, said getting in the process of development of a system at early stage will help build cocoons around it for protection.
He indicated that many agencies working outside the defence sector take their own decisions concerning foreign purchases of equipment and there was need for guidelines.
Answering a query on the possibility of hacking of defence systems acquired from abroad, Chander said: “We have to see what can be done. We have to ensure that core (system) is protected.”
