The Right to Information (RTI) is an act of the Parliament of India & Delhi Legislative Assembly which sets out the rules and procedures regarding citizens' right to access information. It replaced the former Freedom of Information Act, 2000.
Under the provisions of RTI Act, any citizen of India may request information from a "public authority" (a body of Government or "instrumentality of State") which is required to reply expeditiously or within thirty days. In case of the matter involving a petitioner's life and liberty, the information has to be provided within 48 hours.
National Centre for Communication Security is a part of the Department of Telecommunications, which is a Central Govt department. You can file RTI to them.
