In this CyberGuardians episode, we break down the Linux chmod command and why file permissions are critical for system security. Learn how to read permission strings like -rw-rw-r--, understand the numeric values (755, 644, etc.), and see how attackers might exploit weak configurations. We’ll cover symbolic and numeric methods for modifying permissions, explain how root access impacts control, and give defenders practical tips to secure files the right way. Perfect for anyone looking to strengthen their Linux fundamentals while building a strong security mindset.Music Credit: Emotion By: David Fesliyan
