Why are third party scripts a danger?

Third-party scripts are executed on the user’s browser, basically after all layers of protection we have had concluded their work. Once loaded, these JavaScript components now have full access to our page, they are able to change them, access all information in them (including forms) and can even record keystrokes and save them. Because third-party scripts are hosted on a remote location, site owners are unable to monitor any changes made to them. If and when a third-party vendor is hacked and has its code change to hide malicious activity; we, as site owners are oblivious to it

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

The best thing security pros can do to prevent an attack is to implement technology that controls the access and permissions of every 3rd party JavaScript vendor running on web pages. This insulates websites, their corporate owners, their visitors and private customer data from the inappropriate behaviors of 3rd parties and the more malicious activities of hackers that seek to exploit them.

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.

Source Defense V.I.C.E.

Source Defense provides dynamic prevention for attacks of 3rd party origin. Source Defense’s patent pending solution allows security teams to set and enforce security policies to ensure total control of all 3rd party vendors operating on web pages.

Source Defense is easy to deploy, and even easier to manage and maintain. Utilizing machine learning, market best practices and supervised by our data matter experts, the Source Defense platform automates the initial policy definitions thus simplifying administration, deployment and ongoing 3rd party JavaScript integration.  Policy settings may be modified by the administrator, but the system is continuously consuming experiential data to eliminate the need for cumbersome, ongoing maintenance.

By removing the security considerations from 3rd party integrations, Source Defense saves countless man-hours spent on tests and integrations.  This allows website owners to focus on enhancing user experience and driving web commerce revenues while ensuring the security and privacy of private and payment data.
