Programming Languages for Cyber Security: A look at the most important programming languages used by cyber security professionals for defense, testing, and threat analysis.
Python: Widely used for penetration testing, automation, malware analysis, and scripting security tools due to its simplicity and vast libraries.
C And C++: Essential for understanding exploits, reverse engineering malware, and analyzing low-level system vulnerabilities.
JavaScript: Critical for web security testing, identifying client-side vulnerabilities, and understanding common attack vectors like XSS.
Java: Commonly used in enterprise systems, making it important for securing large-scale applications and backend infrastructures.
Go (Golang): Favored for building fast, scalable security tools and cloud-native security applications with strong concurrency support.
Rust: Gaining popularity for secure system programming thanks to its memory safety features that help prevent common exploits.
SQL: Vital for detecting and preventing SQL injection attacks and securing database-driven applications.
Choosing The Right Language: The best language depends on the role, such as ethical hacking, malware analysis, cloud security, or application security.
