Specialized technical vocabulary used within cybersecurity that can create communication barriers with non-technical audiences, impacting security awareness and organizational defense.

Jargon refers to the specialized vocabulary, acronyms, and technical terminology used within a particular professional field, industry, or group. In cybersecurity, this includes terms like "zero-day exploit," "phishing vector," "SIEM," or "attack surface" — language that enables experts to communicate complex threats, vulnerabilities, and defensive strategies with precision and efficiency. While essential for streamlining discourse among specialists, jargon frequently becomes a barrier to comprehension for those outside the domain.

From a Human Factors & Security Awareness perspective, jargon poses a critical challenge. When cybersecurity professionals fail to translate domain-specific language into accessible terms for non-technical employees, it creates communication gaps that undermine the dissemination of security policies, best practices, and threat intelligence. This linguistic divide can lead to misunderstandings, reduced vigilance, and increased susceptibility to social engineering attacks. Bridging this gap — by replacing or explaining technical terminology in awareness training, policies, and communications — is essential for building a strong security culture and empowering every individual to actively participate in an organization's collective defense.
