Internet Security Threats and Defence Mechanisms (ISTDM)

The rapid growth of internet usage has made cybersecurity a major concern for individuals, businesses, and governments. With more people and organizations relying on the internet for communication, banking, and data storage, the risk of cyber threats as increased. These threats can lead to data theft, financial losses, privacy breaches, and operational disruptions. To defend against these risks, organizations use firewalls, encryption, intrusion detection systems, and multi-factor authentication. New technologies like artificial intelligence (AI), blockchain, and Zero Trust Architecture (ZTA) are improving cyber security. AI helps detect unusual activity and prevent attacks, block chain ensures secure transactions, and ZTA ensures that no user or device is trusted by default. This study highlights the importance of strong cybersecurity measures, regular updates, user awareness, and proactive defense strategies to protect against evolving threats.
