REVIEW PAPER ON NETWOTK SECURITY PROTOCOLS AND THREAD MITIGATION

Information Science and Engineering

During a period wherein threats from hackers like ransomware infections, phishing attacks, and denial-of-service (DoS) incidents are constantly changing and developing harder to understand, security for the network must be maintained for safeguarding data as it transfers between systems that are interdependent Comprehensive safety precautions are of greater importance than ever in safeguarding sensitive data and maintain business continuity as organizations concentrate increasing in importance on electronic mediums and services offered through the cloud. Countless defense methods, including firewalls, intrusion detection systems (IDS), cryptography, and secure access protocols, are included in measures to safeguard the network. But because the digital world increasingly interdependent, scammers are coming up with new ways to take advantage over shortcomings, and requesting for more advanced and flexible safety procedures. Encrypting information, identification, and secure channels of communication are some of the most prevalent network security procedures. Specifically in sensitive activities like credit card transactions and e-commerce, SSL/TLS encryption protocols have become crucial for insuring that data transferred over the internet stays confidential and undamaged. A crucial component of Virtual Private Networks (VPNs), IPsec is a protocol for protection created to safeguard information transfers across IP networks. It combines authentication and encryption to preserve data integrity. Additionally, technologies like WPA3 and Secure Shell (SSH) have become crucial for defending unsecured wireless networks and securing distant connections to network laptops. respectively. Public Key Infrastructure (PKI) delivers strong security and authentication solutions to secure transactions over the internet, while methods of identification like Kerberos and Kerberos ensure that only authorized users and devices have access to vital resources. As intrusions get increasingly sophisticated, security measures for networks are integrating machine learning (ML) and artificial intelligence (AI) in an attempt to improve their capacity to identify, stop, and react to new threats instantly. Organisation may create a multi-layered security posture that reduces risks and boosts confidence in the digital environment through the combination of these technological enhancements using best practices involving frequent audits, employee training, and constitutional compliance.
