Information Technology (IT), has seen a dramatic transformation in the past few years. It has opened up new opportunities for businesses and changed the way we live our lives. Most businesses have well-oiled systems for developing, releasing, maintaining and updating software and systems. However, security is a key component of software development due to the increasing risks and concerns associated with insecure software. Companies and organizations have had the need to be more vigilant in light of increasing system threats.

Software and system security are important aspects to ensure that software and systems work effectively and are under control. CompTIA CySA+ certification covers all aspects of software and system security.
The CompTIA Cybersecurity Analyst+ certification, also known as CySA+, is a vendor-neutral certification that certifies cybersecurity, threat and vulnerability analysts. It focuses on security analysis and the actual application security solutions in real-world scenarios.
Domains of CySA+

Domain 1: Threat and vulnerability management (22%)
Domain 2: Software and Systems Security (18%)
Domain 3: Security Operations and Monitoring (25%).
Domain 4: Incident Response (22%)
Domain 5: Compliance Assessment and Assessment (13%)
This article gives an overview of CompTIA CySA+ Domain 2 Software and Systems Security.
CompTIA CySA+ 2: Software and Systems Security
Software and Systems Security are the second domain of the CompTIA CySA+ certification exam. The domain has an 18% weightage. The second domain of the CySA+ certificate will teach you how to assess and integrate security in your organization’s software, hardware, and software. You will also learn how to use the Software Development Life Cycle and its security implications to make sure that your software is secure throughout its lifecycle. It will cover how to make sure that any cloud services you may inject into your environment are secure to allow your apps and systems to run. Security is essential to ensure integrity, authentication, availability.
Software security is a type computer security that focuses primarily on the secure design and implementation software using the most current technologies, tools, methods, and tools. It focuses on avoiding software bugs, flaws, and vulnerabilities. For a device to work at its best, security is crucial. This includes authentication, software updates, antivirus protection, customizations, and authentication. System security covers all aspects of accessing information assets.
The following subtopics are covered in the second domain of CompTIA CySA+ certification exam:
Apply security solutions to infrastructure management in a given situation
Software assurance best practices
Hardware assurance best practices explained

1. Apply security solutions to infrastructure management to a given scenario. This subsection will discuss security solutions for infrastructure managing. It addresses the most important areas of Identity and Access Management (IAM). This subsection will discuss how to reflect a wider identity in a world with many connected devices, people, and process. This section will focus on the main infrastructure models, cloud vs. traditional. The domain will also address issues related to asset management, such as asset tagging or change management. It will show you how to describe virtual and physical segmentation, jump boxes, system isolation with an air gap, and system isolation with a water gap. This section will also include the software-defined virtual private cloud (VPC), virtual private network (VPN) and serverless architectures.
2. Software assurance best practices explained: Software assurance refers the development and execution methods.
