Cybersecurity isn't just about firewalls and antivirus software—it's about understanding the complex interplay between technical systems and human psychology. In this continuation of our Security+ series, we explore the multifaceted world of attack surfaces, threat vectors, and social engineering techniques that cybercriminals employ.

We start by breaking down what constitutes an attack surface—those vulnerable points where unauthorized users might attempt to breach your systems. From physical hardware and network components to applications and human elements, each represents a potential entry point for attackers. We then explore the pathways attackers use to exploit these vulnerabilities, from vulnerable software and network vectors to more devious approaches like lure-based and message-based vectors.

The episode takes a deep dive into social engineering—the art of manipulating human behavior rather than exploiting technical flaws. Through real-world examples, including my own experience with an attempted password reset scam, we demonstrate how attackers use techniques like impersonation, pretexting, phishing, and business email compromise to bypass even the most sophisticated security systems. One of my students shared how his sister's company lost $10,000 when an attacker impersonated the vacationing CEO and requested a wire transfer—a stark reminder that human vulnerabilities often pose the greatest security risk.

Whether you're studying for Security+ certification or simply want to better protect yourself and your organization, this episode provides essential insights into the psychological aspects of cybersecurity. Understanding these concepts is crucial not just for IT professionals, but for everyone who uses digital technology. Have you ever encountered a social engineering attempt? How did you recognize and respond to it?
