Cybersecurity leaders are under increasing pressure to prevent attacks before they occur, and the key to effective defence lies in the initial settings chosen. In this article, Yuriy Tsibere discusses how implementing default policies such as deny-by-default, Multi-Factor Authentication (MFA) enforcement, and Application Ringfencing™ can significantly reduce various risks. By making strategic adjustments—like disabling Office macros and blocking outbound server traffic—organisations can create a fortified environment that is difficult for attackers to breach. Embracing a security-by-default mindset not only simplifies security management but also minimises the attack surface, enabling teams to stay ahead of evolving threats.
The landscape of cybersecurity has transformed dramatically since the “Love Bug” virus in 2001, evolving from a mere nuisance to a billion-dollar criminal enterprise. This shift necessitates proactive defence strategies that focus on preventing threats from infiltrating networks rather than merely responding to them. Chief Information Security Officers (CISOs), IT administrators, and Managed Service Providers (MSPs) require solutions that inherently block attacks by default, rather than relying solely on detection after the fact. While industry frameworks like NIST, ISO, CIS, and HIPAA offer guidance, they often lack the specific, actionable steps needed for effective implementation. For those stepping into new security leadership roles, the objective is clear: thwart as many attacks as possible while maintaining a collaborative relationship with the IT team. Adopting a security-by-default approach—configuring systems to block risks from the outset—can be instrumental in achieving this goal.
