Successfully managing an Information Security environment requires a strong focus on Architecture and Design. In fact, Architecture and Design are not only important but vital components in preparing for the CompTIA Security+ Certification Exam. This article will explore the role of Architecture and Design in Information Security and its relevance to the Security+ exam. However, it’s important to note that this article alone may not provide enough coverage of the Architecture and Design portion of the exam. As such, Security+ candidates should also refer to our comprehensive series on the Security+ SY0-601 exam.
Overview of Domain 2: Architecture and Design:
Domain 2 of the CompTIA Security+ certification course covers a wide range of topics related to information security architecture and design. The main objective of this domain is to assess a candidate’s ability to design, implement, and maintain secure and effective information systems, networks, and applications. The subtopics are:
- Scenarios and objectives for frameworks, optimal methodologies, and secure configuration guides.
- Implementation of secure network architecture concepts
- Implementation of secure systems design
- Importance of secure staging deployment concepts
- Security implications of embedded systems
- Secure application development and deployment concepts
- Cloud and visualization concepts
- Resiliency and automation to reduce risk
- Importance of physical security controls
Each of these topics is critical for maintaining a secure information environment and mitigating potential risks and vulnerabilities. Below, we will discuss each subtopic in more detail.

Scenarios and objectives for frameworks, optimal methodologies, and secure configuration guides:
The use of frameworks, best practices, and secure configuration guides is essential for ensuring a secure information environment. This subtopic covers the use cases and purposes of various security frameworks, such as ISO 27001, NIST, and COBIT. Additionally, candidates are expected to understand the importance of implementing security best practices, such as the principle of least privilege, separation of duties, and defense-in-depth. Candidates should also be familiar with secure configuration guides, such as the Center for Internet Security (CIS) benchmarks.
Implementation of secure network architecture concepts:
A secure network architecture is essential to safeguarding against cyber-attacks. This subtopic covers the implementation of secure network architecture concepts, such as network segmentation, access controls, and VPNs. Candidates are also expected to understand the importance of secure network protocols, such as SSH and HTTPS, and the use of network security devices, such as firewalls, intrusion detection systems (IDS), and intrusion prevention systems (IPS).
Implementation of secure systems design:
Implementing secure systems design is essential to protect systems and data from potential threats and vulnerabilities. This subtopic covers the implementation of secure system design concepts, such as secure boot, secure BIOS, and secure firmware. Candidates should also be familiar with the use of security controls, such as antivirus software, host-based firewalls, and data encryption, to ensure the security of systems.
Importance of secure staging deployment concepts:
Secure staging deployment concepts are important to ensure a secure and controlled release of software and systems. This subtopic covers the importance of testing and verifying software before deployment, as well as the use of secure staging environments, such as development, testing, and production environments. Candidates should also be familiar with the use of version control systems and the importance of secure coding practices.
Security implications of embedded systems:
As embedded systems become more common, it is important to understand the security implications of using such systems. This subtopic covers the potential risks and vulnerabilities associated with embedded systems, such as remote code execution and buffer overflows. Candidates should also be familiar with the use of secure coding practices, such as input validation and error handling, to mitigate potential risks.
Implementation of Secure Systems Design:
The implementation of secure systems design is crucial to ensure that the information systems are secure from the start. This subtopic covers the process of designing and implementing secure systems using industry-standard best practices, including secure system development lifecycle (SDLC) methodologies, and secure coding techniques. It also includes topics such as designing and implementing secure operating systems, mobile devices, and embedded systems.
Understanding Security Implications of Embedded Systems:
Embedded systems are specialized computer systems designed for a specific purpose within larger systems. These systems are present in everyday devices such as cars, medical equipment, and industrial control systems. As such, they present unique security challenges that need to be addressed. This subtopic covers the security implications of embedded systems and the best practices for securing them.
Grasping Secure Application Development and Deployment Concepts:
Applications are a critical component of information systems, and securing them is essential for maintaining the security of the entire system. This subtopic covers secure application development methodologies, secure coding practices, and secure deployment techniques. It also covers the importance of patch management, vulnerability scanning, and penetration testing in ensuring the security of applications.
Understanding Cloud and Virtualization Concepts:
Cloud computing and virtualization are transforming the way organizations manage their information systems. However, they also present unique security challenges that need to be addressed. This subtopic covers the security implications of cloud computing and virtualization, as well as the best practices for securing cloud and virtualized environments.
Recognizing the Need for Resiliency and Automation to Reduce Risk:
Organizations need to be able to recover quickly from security incidents to minimize the impact on their operations. This subtopic covers the best practices for designing and implementing resiliency and automation solutions that help organizations reduce risk and recover quickly from security incidents.
Understanding the Importance of Physical Security Controls:
Physical security controls are an essential component of information security. This subtopic covers the best practices for designing and implementing physical security controls, including access controls, surveillance systems, environmental controls, and fire suppression systems.
