Social Engineering Attacks on SMBs — Risk Assessment Guide
Social engineering attacks manipulate people — not technology — into revealing sensitive information or taking actions that compromise security. Unlike technical attacks, they exploit human psychology: authority, urgency, fear, helpfulness, and trust. Even organizations with strong technical controls are vulnerable if employees lack social engineering awareness.

How Social Engineering Works — Step by Step
- Phishing: deceptive emails impersonating trusted senders to steal credentials or install malware
- Vishing: phone calls impersonating IT support, banks, or government agencies to extract information
- Smishing: SMS messages with malicious links or requests for sensitive information
- Pretexting: fabricated scenarios ("I'm from IT support, I need your password to fix an issue")
- Baiting: USB drives left in parking lots loaded with malware; attractive downloadable content
- Tailgating: following an employee through a secure door without authenticating

Prevention Controls
Implement these controls to reduce your social engineering exposure. Prioritize based on your current gaps.
- Security awareness training with simulated phishing, vishing, and social engineering exercises
- Verification procedures: callback on known numbers before acting on email requests for money or access
- Information access controls limiting what employees can reveal to callers or visitors
- Clean desk policy and visitor escort procedures for physical social engineering
- Multi-factor authentication so stolen passwords alone are insufficient
- Culture of security: reward reporting suspicious contacts, not just reporting incidents
