Checkmarx refers to a software security platform that specializes in identifying and mitigating vulnerabilities in application code. This skill encompasses the use of static application security testing (SAST) and other methodologies to analyze source code and detect security flaws early in the development process. Knowledge of Checkmarx is utilized to enhance software security by integrating security practices into the software development lifecycle, thereby reducing the risk of security breaches and ensuring compliance with industry standards.

Code Access Security is a security model built into the .NET Framework that controls access to code and resources at run time. It allows software developers to specify permissions and restrictions on code based on factors such as its origin, digital signature, and user identity. This helps ensure that malicious code cannot access privileged resources, and that the system remains secure and stable.

Dynamic Application Security Testing (DAST) refers to a security testing methodology that evaluates applications while they are running to identify vulnerabilities and security weaknesses. This skill involves simulating attacks on a web application to uncover potential security flaws that could be exploited by malicious actors. Knowledge of Dynamic Application Security Testing (DAST) is used to enhance application security by providing insights into real-time vulnerabilities, enabling organizations to remediate issues before they can be exploited in a production environment.

OWASP is an open community dedicated to improving the security of software applications. They provide lists of vulnerabilities and best practices for developers to follow to ensure secure coding practices. OWASP also offers a range of tools and resources to help identify and address security issues in web applications. Overall, OWASP aims to increase awareness and understanding of application security risks and to promote best practices for secure development.

Static Application Security Testing (SAST) refers to a method of analyzing source code or binaries to identify security vulnerabilities without executing the program. This skill involves the use of automated tools to scan code for potential weaknesses, such as coding errors or insecure practices, early in the development lifecycle. Knowledge of Static Application Security Testing (SAST) is utilized to enhance software security by enabling developers to remediate issues before deployment, thereby reducing the risk of exploitation in production environments.
