Understanding and managing the attack surface is crucial for protecting dealership networks and sensitive data. The attack surface represents all potential points, known as attack vectors, that hackers can exploit to gain unauthorized access or execute cyberattacks. Common attack vectors within dealerships include:

1. Network Perimeter – The boundary between an organization’s internal network and the Internet, protecting the network perimeter is challenging due to factors like cloud computing and remote work.
2. Endpoints – Devices such as servers, workstations, laptops, and mobile devices connected to the network are susceptible to exploitation.
3. Applications and Services – Vulnerabilities in software or misconfigurations within applications and services present opportunities for cybercriminals to exploit.
4. Third-Party Integrations – Vulnerabilities in products or services from external vendors can impact dealership security.
5. Human Elements – Employees constitute a crucial part of the attack surface, making user awareness and training essential.
6. Cloud Services – Misconfigurations in cloud resources are common attack vectors for cybercriminals.
7. Shadow IT – Unapproved software, hardware, portable storage, and personal mobile devices used without IT approval contribute to the attack surface.

The modernization of technology, cloud adoption, and the rise of remote work have expanded the average dealership’s digital footprint. A recent Randori study (a subsidiary of IBM)  revealed that 67% of organizations experienced an expanded attack surface in the past year, with 69% compromised due to mismanaged or misconfigured assets.

In response, a strategic approach that’s gaining prominence is Attack Surface Reduction (ASR). ASR involves identifying, assessing, and minimizing the attack surface to mitigate exposure to potential threats. Here’s why ASR is gaining traction in modern cybersecurity:

• Complexity Reduction: ASR simplifies cybersecurity by eliminating unnecessary components and consolidating services, reducing the overall digital footprint.
• Vulnerability Minimization: By reducing the attack surface, dealerships minimize potential points of exploitation.
• Enhanced Visibility: A smaller attack surface facilitates effective monitoring, detection, and response to suspicious behavior.
• Resource Optimization: A streamlined attack surface is cost-effective, allowing resources to be allocated where they can have the most significant impact.
• Improved Security Posture: ASR is a proactive cybersecurity approach that reduces exposure to risks, enhancing the dealership’s ability to defend against threats.

It’s essential that dealerships embrace Attack Surface Reduction to better fortify their cybersecurity defenses, stay ahead of the cybercriminal, and protect their reputation.
