      Defending Against Cybersecurity Threats

THE COMPTIA CYBERSECURITY ANALYST+ EXAM OBJECTIVES COVERED IN THIS CHAPTER INCLUDE:

      Domain 1: Threat Management

      ✓ 1.3 Given a network-based threat, implement or recommend the appropriate response and countermeasure.

      ✓ 1.4 Explain the purpose of practices used to secure a corporate environment.

       Cybersecurity analysts are responsible for protecting the confidentiality, integrity, and availability of information and information systems used by their organizations. Fulfilling this responsibility requires a commitment to a defense-in-depth approach to information security that uses multiple, overlapping security controls to achieve each cybersecurity objective. It also requires that analysts have a strong understanding of the threat environment facing their organization in order to develop a set of controls capable of rising to the occasion and answering those threats.

      In the first section of this chapter, you will learn how to assess the cybersecurity threats facing your organization and determine the risk that they pose to the confidentiality, integrity, and availability of your operations. In the sections that follow, you will learn about some of the controls that you can put in place to secure networks and endpoints and evaluate the effectiveness of those controls over time.

      Cybersecurity Objectives

When most people think of cybersecurity, they imagine hackers trying to break into an organization’s system and steal sensitive information, ranging from Social Security numbers and credit cards to top-secret military information. Although protecting sensitive information from unauthorized disclosure is certainly one element of a cybersecurity program, it is important to understand that cybersecurity actually has three complementary objectives, as shown in Figure 1.1.

Figure 1.1 The three key objectives of cybersecurity programs are confidentiality, integrity, and availability.

      Confidentiality ensures that unauthorized individuals are not able to gain access to sensitive information. Cybersecurity professionals develop and implement security controls, including firewalls, access control lists, and encryption, to prevent unauthorized access to information. Attackers may seek to undermine confidentiality controls to achieve one of their goals: the unauthorized disclosure of sensitive information.

      Integrity ensures that there are no unauthorized modifications to information or systems, either intentionally or unintentionally. Integrity controls, such as hashing and integrity monitoring solutions, seek to enforce this requirement. Integrity threats may come from attackers seeking the alteration
