Chairing a review meeting in the ministry, he cautioned against the challenges being posed by crimes in cyberspace and called for effective measures to improve cyber security.

Rajnath Singh called for greater vigilance against evolving cyber threats and called for regular cyber auditing of IT infrastructure of all organisations under the Home Ministry.

Expressing concern over rising misuse of internet for child pornography and other obscene material, he directed the ministry officials to expedite the launch of an online cybercrime reporting portal.

According to the statement, the portal will enable affected people in states and union territories to lodge complaints which will be investigated by the respective law enforcement agencies and action taken for removal of such content.
