This paper discusses research-based findings of the issues addressed by connectivity, traffic flow, and applied statistics in cyber security, hence their impacts thereof. In a brief but detailed approach, the paper addresses the impacts of the incorporation of aforementioned disciplines in cybersecurity, thus allowing for further research on them to enforce security in the cyber-ecosystem. The paper is divided into three sections, with the first section describing the emerging issues that face advances in connectivity of devices and the implications of cyber security to curb attacks. The second section is devoted to traffic flow monitoring for detection of attacks, thus, the role it plays in enforcing cyber security. Finally, the third section will illustrate how applied statistics using formulated mathematical models can be applied for the purpose of cyber security. In summary, this paper seeks to address that cyber security is a critical component for networks and must be considered to facilitate better network performance.
