What is third-party monitoring?
In the field of cybersecurity, third-party monitoring is the practice of gathering and analyzing data on the security posture of vendors within an organization’s supply chain. By monitoring the security performance of third parties, organizations can better defend against cyber threats that originate in a vendor’s IT ecosystem.
What are third-party breaches?
A third-party breach occurs when attackers access a company’s IT systems by using credentials or sensitive information stolen from a vendor within the company’s supply chain.
What is dark web monitoring?
Dark web monitoring is the process of tracking activity, conversations, and transactions on sites on the dark web. This is where cybercriminals tend to congregate online as they plan attacks, share information, and buy and sell the tools of their trade. By surreptitiously monitoring and automatically extracting data from hundreds of thousands of sites, dark web monitoring solutions provide security teams with early warning of imminent threats and a better understanding of the tactics, techniques, and procedures (TTPs) threat actors may use in their attacks.
Understanding third-party risk management
Third-party risk management has become an essential component of security risk management. In recent years, many of the largest cybersecurity breaches originated not as an attack on the company itself, but on third-party vendors. By exploiting weaknesses in a vendor’s security controls, attackers can often gain access to credentials that enable them to easily access the IT environment of the target company to steal money and sensitive information, cause disruption, or damage the business.
Third-party risk management enables businesses to better understand the security posture of the vendors in their supply chain. By using third-party intelligence that highlights the security gaps and exploitable vulnerabilities in vendors' software, organizations can configure their own security controls more effectively, and help vendors identify and remediate threats more successfully.
Sources on the deep and dark web can provide a wealth of intelligence for supply chain monitoring initiatives. The dark web is where threat actors discuss methods, plan attacks and buy and sell tools and data. Cyber security monitoring of dark web forums, illicit marketplaces, and code repositories can provide security teams with automated alerts and in-depth understanding of the threats facing the company’s vendors.
