The best control to reduce the likelihood of a successful network attack through social engineering is security awareness training. Security awareness training is a program that educates and trains employees on the common types, techniques, and indicators of social engineering attacks, such as phishing, baiting, pretexting, and quid pro quo12. Security awareness training also teaches employees how to protect themselves and the organization from social engineering attacks, such as by verifying the identity and legitimacy of the sender or caller, avoiding clicking on suspicious links or attachments, reporting any suspicious or unusual activity, and following the organization’s security policies and procedures. Security awareness training can help to reduce the likelihood of a successful network attack through social engineering, because it can increase the employees’ knowledge, skills, and confidence in recognizing and responding to social engineering attempts, and it can also foster a culture of security and responsibility among the employees. The other options are not the best control, although they may be useful or complementary to security awareness training. Automated controls are technical or procedural controls that are performed by a system or a device without human intervention, such as firewalls, antivirus software, encryption, and backups. Automated controls can help to protect the network from external or internal threats, but they may not be effective against social engineering attacks, which rely on humaninteraction and manipulation.Multifactor authentication is a security mechanism that requires users to provide two or more pieces of evidence to verify their identity and access a system or a service, such as a password, a token, a fingerprint, or a facial recognition. Multifactor authentication can help to prevent unauthorized access to the network, but it may not prevent social engineering attacks, which may persuade users to share or compromise their authentication factors. Employee sanctions are disciplinary actions that are taken against employees who violate the organization’s security policies and procedures, such as warnings, fines, suspensions, or terminations. Employee sanctions can help to deter and punish employees who fall victim to or facilitate social engineering attacks, but they may not prevent or reduce the likelihood of social engineering attacks, and they may also create a negative or fearful work environment.
