The government balances **national security** with **individual civil liberties** by enacting laws that restrict rights only to the extent necessary to protect the nation, while ensuring such restrictions are **reasonable, legal, and proportionate**. Constitutional safeguards like **Articles 19 and 21** guarantee freedoms, but these can be curtailed in the interest of **sovereignty, integrity, public order, or security**. Courts play a key role in reviewing such laws to prevent misuse, ensuring that national security measures do not unduly infringe upon fundamental rights like free speech, privacy, and due process.
