CySA+ domain #1: introduction to threat management

Introduction

CompTIA’s Cybersecurity Analyst certification is a solid cybersecurity certification you can earn which will help boost your information security career. The question remains — what will you have to traverse to earn this solid certification? Simply put, you will need to pass the CySA+ certification exam. 

This exam comprises four domains of knowledge, and the first domain is Threat Management. This article will provide an introductory review of what you will need to know to successfully trek through this domain. You will learn about some commonly used terms, risk assessments, identifying vulnerabilities, identifying threats, determining likelihood, impact and risk. 

Please bear in mind that this article will only detail an introductory view of threat management and you will need to look for subsequent articles to guide you through the rest of the domain.

  • Threat: With regard to cybersecurity, a threat is an outside force may exploit a vulnerability
  • Risk: A risk is the combination of a threat and a corresponding vulnerability. In other words, risk is the intersection of threats and vulnerabilities
  • Risk can also be defined with an equation: Risk = Threat x Vulnerability
