"The top challenge with android is the fake app, which opens customers up to advanced malware. In our focus of putting innovation in the 'before' phase, we are also briefing up our activity in the 'during and after' phase," he said.

Asked about sectors affected by malware, Sivasankaran said generally, financial, energy and retail are affected.

New sectors have come up as targets, like agriculture and IoE and this will exasperate the impact on other sectors, he added.

"There are a lot of connections, from farms to processing to transportation and delivering. In India, financial would be high, government and private sectors are also there. Soon energy and pharmaceuticals too will join," Sivasankaran said.

On the issue of data security, he said it is a focus point for Cisco and the company will continue to make investments.

"USD 2.7 billion investment in Sourcefire says that security is a top investment area. We have a little over 600 employees in the business unit that focuses on securities R&D.

"But, beyond R&D, there is a huge portfolio of people in services and solutions in India. We also bought a company called Cognitive that gave us our intelligence," he added.
