Inter-state coordination and latest technology can play a vital role in countering internal security threat, Punjab Governor Shivraj Patil said on Wednesday.
"We have to understand the threat perception and should be prepared in advance" the former Union home minister said.
Patil said India's security concerns were dynamic and affected by global security environment. He suggested use of new technologies.
"Research and development (R&D) is more important in the defence sector. It should be equipped with latest technology in regards to aircraft, submarines and guns that are required," the Chandigarh administrator said.
He also emphasised on developing R&D in private industry for which, he said, the government was giving a lot of concessions.
Stressing upon increasing the number of policemen and police stations, Patil said there were 6.5 lakh villages in the country and the number of police stations was less than 14,000.
The ratio between police and public should be maintained to provide better security cover, he said, adding that the states should have defence as well as police universities to impart the required training.
