Which approach reduces the risk of social engineering attacks?

Regular security awareness training directly addresses the human manipulation on which social engineering depends. Effective programs teach users to recognize phishing, pretexting, impersonation, malicious links, unusual payment requests, and attempts to obtain credentials or confidential information. Cisco Secure Awareness Training combines employee education with phishing simulations so organizations can reinforce safe behavior and measure susceptibility, as described in Cisco’s security awareness documentation. NAT traversal enables connectivity through address translation and does not educate users or validate deceptive requests. Port security and DHCP-spoofing controls address unauthorized devices and Layer 2 attacks, not psychological manipulation. Restricting outbound TCP traffic can limit certain command-and-control paths, but it does not prevent users from revealing information or approving fraudulent actions. Therefore, recurring awareness training is the most relevant preventive control.
