According to a article in the Indian Hindustan Times, "Indian diplomats now cannot open a Facebook account, use external e-mail services, or write blogs, thanks to new rules and much stricter firewalls aimed at preventing cyber attacks and leakage of classified information. Over the past eight months, the Indian Ministry of External Affairs has been overhauling its computer network security, putting up layers of barriers against intrusions into the network, officials associated with cyber security said. There are almost 600 computers at its headquarters at South Block, about half of which are connected to the Internet. Classified work is typically done on stand-alone computers, usually with the external drives removed. "We have set up a unified threat management system for the ministry. This simultaneously uses eight levels of protection like firewalls and spam mail filtering," said a senior official.
"We are also requesting and encouraging more responsible behaviour from our staff when working online," the official told IANS, requesting anonymity. A circular issued last week asked officials not to log on to social networking sites, specifically citing Facebook, Orkut and Ibibo as examples. The other prohibited practices include download of peer-to-peer music using sites like Kazaa and sharing of photos through Flickr and Picasa. The circular also discourages using services like G-mail, Yahoo! or Hotmail for official communication. A similar circular, officials said, had been issued in the Prime Minister's Office in December. But the matter is even more critical for the foreign office as officials posted in Indian missions abroad or on foreign tours tend to use web-based mail rather than the ministry's own mail system. "We have had cases of senior officers using G-mail or other similar accounts abroad for official work, only to find some form of tampering when they return," the official said, adding people have been told to change their web-mail passwords if they had opened the account during foreign tours. The missions have been told to use their official mail ID issued by the National Informatics Centre for communication. But several missions have complained that the mail home page was inaccessible due to port blocks by local Internet service providers. They have been asked to contact their service providers to unblock the site. "We want to secure communications with Indian missions through private networks. This may be implemented in the next few months," said an official working with the technical team in the ministry.
