CYBER SECURITY IN MODERN WORLD

      Cybersecurity is the practice of protecting computers, networks, data, and digital systems from cyber threats such 
      hacking, malware, phishing, and data breaches. 
      In today's interconnected world, cybersecurity is essential for safeguarding personal information, business operations,   
      financial transactions, and critical infrastructure. 
      As technology advances, cyber attacks are becoming more sophisticated, making strong security measures increasingly 
      important.

      Transition to Quantum Security

     With the development of quantum computing, traditional encryption methods may become vulnerable because powerful 
     quantum computers could potentially break current cryptographic algorithms much faster than classical computers.
     Quantum security, also known as post-quantum cryptography, focuses on developing new encryption techniques that can
     resist attacks from both classical and quantum computers.
     This emerging field aims to ensure long-term data protection and secure communication in the future quantum era.
