By: Mark Birch

Overview of this book

CompTIA Advanced Security Practitioner (CASP+) ensures that security practitioners stay on top of the ever-changing security landscape. The CompTIA CASP+ CAS-004 Certification Guide offers complete, up-to-date coverage of the CompTIA CAS-004 exam so you can take it with confidence, fully equipped to pass on the first attempt. Written in a clear, succinct way with self-assessment questions, exam tips, and mock exams with detailed explanations, this book covers security architecture, security operations, security engineering, cryptography, governance, risk, and compliance. You'll begin by developing the skills to architect, engineer, integrate, and implement secure solutions across complex environments to support a resilient enterprise. Moving on, you'll discover how to monitor and detect security incidents, implement incident response, and use automation to proactively support ongoing security operations. The book also shows you how to apply security practices in the cloud, on-premises, to endpoints, and to mobile infrastructure.

Recognizing common attacks

Attacks against systems and software are a real threat, based on the fact that systems need to be made accessible to business users and customers. For web applications, the typical scenario is a customer-facing application server behind a firewall, able to communicate with intranet-based services. A typical deployment can be seen in Figure 7.7, where the inputs will be through web-based forms run on the client browser and the results forwarded to the web application server:

Figure 7.7 – Web application server located in DMZ

When we secure our networks using secured firewalls, it is difficult to attack the intranet services directly, so it is the web application server that is targeted. This is where the attacker will direct the attacks. In this section, we will focus on attacks that use the model shown in Figure 7.7.

Directory traversal is when an attacker can input syntax that allows them to move...
