Pair programming is a collaborative software development technique in which two programmers work together at a single workstation. One programmer, known as the 'driver,' writes code while the other, the 'observer' or 'navigator,' reviews each line of code as it is typed. The two programmers frequently switch roles to maintain engagement and share knowledge. This approach enhances code quality, encourages knowledge sharing, and helps identify bugs early. In cybersecurity, pair programming can be particularly effective for secure coding practices, as it allows for real-time review and discussion of potential vulnerabilities, reducing the risk of security flaws in the software.
