“Invisible warfare” refers to conflict that occurs in the digital realm, where cyber-attacks, espionage, misinformation, and other covert operations are used to damage, disrupt, or gain an advantage over an adversary without traditional military engagement. This form of warfare is characterized by its stealth, making it difficult to detect and attribute responsibility, thereby posing significant challenges to national security.
For India, invisible warfare presents a range of threats. Cyber-attacks can target critical infrastructure, such as power grids, financial systems, and communication networks, leading to widespread disruption and economic losses. Espionage activities can compromise sensitive information, impacting national security and defense capabilities. Additionally, misinformation campaigns can influence public opinion and destabilize social and political environments. Given the geopolitical tensions with neighboring countries like China and Pakistan, the frequency and sophistication of such cyber threats have increased.
To address these challenges, India has taken several steps to strengthen its cybersecurity framework. The establishment of the National Cyber Security Policy in 2013 aimed to create a secure and resilient cyberspace. Initiatives like the Indian Computer Emergency Response Team (CERT-In) have been crucial in coordinating responses to cyber incidents and facilitating information sharing among stakeholders. The government has also launched the National Critical Information Infrastructure Protection Centre (NCIIPC) to safeguard critical information infrastructure.
Furthermore, efforts to enhance cybersecurity education and training are underway to address the shortage of skilled professionals. Collaborations with international partners and private sector engagement have been encouraged to bolster India’s cyber defense capabilities. Despite these measures, continuous advancements and updates are essential to stay ahead of evolving threats in the realm of invisible warfare.

Imagine you need to transmit confidential information. Encryption acts as a digital lock, safeguarding your message from unauthorized access. There are two main encryption methods, each with distinct advantages:
Symmetric Encryption:
This method utilizes a single, shared secret key for both encryption and decryption. It functions similarly to a padlock with one key – whoever possesses the key can unlock the message. This approach offers exceptional speed and efficiency, making it ideal for encrypting large data volumes. However, you have to securely share the secret key beforehand, and if the secret key is found by anyone else they can also access the information.
Asymmetric Encryption:
This method uses a pair of mathematically linked keys: a public key and a private key. The public key is widely available, allowing anyone to encrypt messages intended for you. The private key, however, remains strictly confidential and is used solely for decryption.
Think of it as a secure mailbox with a public slot for anyone to deposit messages and a private key, only you possess, to retrieve them. This method prioritizes security since the private key is in your control.
Here are some other common use cases for symmetric encryption:
