Understanding and managing your organization’s attack surface is crucial in today’s cybersecurity landscape. A recent analysis by Bitdefender reveals that a significant portion of security incidents involve the misuse of legitimate tools rather than traditional malware. This insight has led to the development of a 45-day Internal Attack Surface Assessment aimed at helping organizations identify and mitigate these vulnerabilities.
Why Legitimate Tools Pose a Threat
Research indicates that trusted utilities like PowerShell and MSBuild are often exploited by threat actors, with Bitdefender identifying their misuse in 84% of high-severity incidents. This trend highlights a shift from traditional malware attacks to tactics that involve ‘living off the land’ using the same tools utilized daily by IT teams.
A clean installation of Windows 11 includes numerous built-in tools that can be leveraged by attackers. Bitdefender’s telemetry data shows that PowerShell is active on a majority of endpoints, often without the user’s knowledge. This over-entitlement problem emphasizes the need for proactive cybersecurity strategies.
The Assessment Process
Bitdefender’s assessment employs their Proactive Hardening and Attack Surface Reduction (PHASR) technology over a 45-day period. The process starts with building behavioral profiles for machine-user pairs, followed by an evaluation of the attack surface. Participants receive an exposure score and prioritized findings, allowing them to make informed decisions on risk mitigation.
Optional reduction strategies are available, either through manual controls or PHASR’s automated enforcement. A final review quantifies the reduction in the attack surface, providing insights into potential shadow IT and unauthorized tools uncovered during the process.
Benefits for Organizations
The assessment offers tangible benefits for various stakeholders. CISOs gain a measurable and defensible exposure number, reducing the burden on security operations by eliminating unnecessary investigations. Business decision-makers can demonstrate ongoing risk reduction, aligning with regulatory and insurance requirements.
In summary, understanding your organization’s attack surface is more critical than ever. By utilizing the Internal Attack Surface Assessment, organizations can gain a comprehensive view of their risk landscape and take proactive steps to mitigate potential breaches.
For organizations with a Windows-centric environment and more than 250 users, this assessment provides a strategic advantage. As cyber threats continue to evolve, the ability to rapidly identify and address vulnerabilities becomes paramount. Request your complimentary assessment today to enhance your cybersecurity posture.
