Why are third party scripts a danger?
Here’s what you can do …
Luckily, there are steps that security teams can take to mitigate or even eliminate the risks of 3rd party vendors. There are practical considerations for security pros as they seek to protect their companies from website supply chain attacks.
Prevention is the best option
Prevention-level approaches for addressing client-side connections not only secure the organization but are required for adequate data control defined by regulatory compliance (e.g. GDPR and California’s newly passed Digital Privacy Law). Without the ability to control private customer data and prevent unauthorized access by 3rd party website vendors or hackers, an organization is in a state of non-compliance.
Monitoring and detection
Monitoring provides a detection-based approach that provides a less secure, reactive methodology. The major inadequacy of detection approaches is that they are incapable of preventing attacks. Even with a multitude of global sensors, detection schemes often miss highly targeted and hyper-segmented attacks altogether. Additionally, a detection event signals leakage of customer data and constitutes a compliance violation that requires disclosure. The resulting fines, PR crises, remediation and operational fire drills are often significant. Fundamentally, these approaches are not scalable and the persistence of the underlying vulnerability renders these approaches ineffective.
Vendor due diligence assessments
Many organizations, and especially those under strict compliance mandates, perform routine, comprehensive vendor security assessments. Although, well intended and highly recommended, such exercises provide point-in-time assessments. They do not provide prevention or even continuous detection. Although these assessments should be part of a comprehensive security program they are in no way adequate as a stand-alone approach to mitigating or preventing website supply chain 3rd party risk.
Restricting the usage of 3rd party tools
Exercising a debilitating level of caution by limiting or restricting the usage of beneficial 3rd party tools on websites is generally counterproductive to the overall goals of the business. Limiting the number of tools able to be deployed on an organization’s website limits the ability to provide an engaging user experience and extract meaningful analytics. This methodology makes delivering a compelling, differentiated, and dynamic web presence difficult.
