The ISC2 Strategic Congress 2026 in Denver emphasizes the importance of threat modeling as a foundational principle for any security program This article explores zero trust environment. . Lora Vaughn, a cybersecurity expert and former CISO, founder of her own consulting firm, The Vaughn Group, has developed a straightforward four-question threat modeling exercise that can be applied across various organizations, from the NSA to small-to-medium businesses (SMBs).
However, this turned out to be more of a customizable guiding principle rather than a straightforward prescription; and architecting a true zero-trust environment requires a significant investment in systems that will prove to be a much longer journey than many in the industry had anticipated. Zero times anything remains zero.
Additional controls that truly deliver, as Vaughn explains, include multifactor authentication (MFA) everywhere, which she considers "non-negotiable" and encourages CISOs to "fight for." An asset inventory, even a simple spreadsheet, is invaluable, and it "beats doing nothing." Patching vulnerabilities that have been exploited, resisting the temptation to grant everyone admin access, and testing backups are also on the list.
— Taking the Threat Model Findings to Management It might be tempting for cybersecurity teams to tackle these four questions alone, but Vaughn advised that including management in these discussions will help better align priorities with the broader business and will help management understand the potential consequences of neglecting cybersecurity.
