Cyber Resilience through Real-Time Threat Analysis in Information Security ()
1. Introduction
Information security is defined at the outset of the document as safeguarding data against unauthorized access, use, disclosure, disruption, alteration, or destruction. It includes protecting sensitive data, including financial records, intellectual property, and personal information, as well as both digital and physical data. Information security procedures are designed to protect data’s availability, confidentiality, and integrity often referred to as the “CIA triad”. Conversely, network security focuses on preventing unwanted access, misuse, or alteration to a network infrastructure, which includes hardware, software, and data. It focuses on protecting network devices and communication channels, including intrusion detection systems (IDS), switches, routers, and firewalls. The objectives of network security measures are to guard against unwanted access, identify and eliminate risks, and guarantee the privacy, availability, and integrity of network resources [2] .
Network security and information security have different approaches and objectives, yet they both aim to secure data. While network security primarily concentrates on safeguarding the network architecture and communication channels, information security is more comprehensive and covers all facets of data protection, including digital and physical data. Network security is essentially one of the components of information security, which is a larger notion [2] .
