Cloud, Mobile, and IoT Security

In this chapter from CompTIA PenTest+ PT0-002 Cert Guide, 2nd Edition, you will learn about different attacks against cloud, mobile, and IoT implementations.

This chapter is from the book

This chapter covers the following topics related to Objective 3.4 (Given a scenario, research attack vectors and perform attacks on cloud technologies.) and Objective 3.5 (Explain common attacks and vulnerabilities against specialized systems.) of the CompTIA PenTest+ PT0-002 certification exam:

  • Researching attack vectors and performing attacks on cloud technologies

  • Explaining common attacks and vulnerabilities against specialized systems

The adoption of cloud technology and cloud services has revolutionized how organizations develop, host, and deploy applications and store data. In addition, mobile devices and Internet of Things (IoT) devices communicate using a diverse set of protocols and technologies. Mobile and IoT devices also often communicate with applications hosted in the cloud. All these technologies and architectures increase the attack surface and introduce a variety of cybersecurity risks. In this chapter, you will learn about different attacks against cloud, mobile, and IoT implementations.
