Final Thesis – Network security

This research explores the critical role of network security in protecting organizational and personal data amidst increasing cyber threats. It reviews fundamental security measures such as firewalls, intrusion detection systems, encryption, and employee awareness training, assessing their effectiveness through case studies like the Equifax and Yahoo breaches. The study underscores the significance of regulatory compliance with standards like GDPR, PCI DSS, and HIPAA, which enforce data protection protocols and mitigate legal repercussions. The rapid advancement of technology, including IoT and cloud computing, necessitates continuous adaptation of security strategies. By implementing layered security policies, organizations can significantly reduce risks, prevent data breaches, and maintain trust with clients and stakeholders. Strong network security remains essential in the ongoing battle against cybercrime.
