An attack path is a route that malicious actors follow when infiltrating the IT environment of target organizations. While navigating attack paths, adversaries commonly bypass security controls, leverage security gaps, and escalate privileges to gain access to and compromise assets within a target network or system. Mapping an attack path is a crucial part of Automated Penetration Testing, allowing organizations to understand potential attacker routes and proactively mitigate risks.
The concepts of attack paths, attack vectors, and attack surfaces are closely interconnected, but there are important distinctions to be drawn between them.
An attack path is the chain of steps that attackers take as they seek to access specific assets to achieve their objectives. Once an attacker has leveraged an attack vector to gain entry to the organization’s network, they utilize attack paths to navigate it.
The term “attack vector”, on the other hand, refers to the method an attacker uses to exploit vulnerabilities in security measures and gain access to a target system of a network. This could include malware, SQL injection, Man-in-the-Middle attacks (MitM), or social engineering techniques such as phishing. In this sense, an attack vector relates to the initial “break-in point” through which an attacker penetrates an organization’s network perimeter.
Lastly, the term “attack surface” comprises all possible vulnerabilities or points of entry within an organization’s IT environment. It is the sum total of all available attack vectors and encompasses applications, systems, and network infrastructure.
Attack paths are important because they can give insights into the likelihood and potential risk of attacks. By identifying and accurately mapping routes that attackers might take, organizations can better understand how their security measures might be penetrated, and by extension, the level of risk to which their critical data assets are exposed. As such, analyzing attack paths can empower more informed decision-making, enabling organizations to identify controls that need upscaling, prioritize them, and allocate resources accordingly to ensure maximal protection against known threats.
The following are some of the primary benefits of understanding attack paths:
There are a variety of tools that organizations can utilize to aid them with attack path analysis.
Network mapping tools are commonly used to get an overview of network topology and uncover possible attack paths. Penetration testing tools and vulnerability scanners can also be of use by enabling organizations to test the effectiveness of security controls and identify areas where exploitable vulnerabilities exist.
Additionally, organizations may also leverage threat intelligence platforms to their advantage, as they provide insights into emerging threats and indicators of compromise, allowing security teams to identify attack paths and make informed decisions about how to proactively protect their assets.
In an evolving threat landscape, proactivity is paramount. To protect vital digital assets from would-be attackers, organizations must actively investigate and analyze the potential routes they might take in order to access them, and this is what attack path management is all about. By engaging in attack path analysis and management, organizations establish complete visibility over their IT environments and map all possible attack routes so as to strengthen their defenses pre-emptively. In doing so, they can reduce the chance of a successful attack, mitigate risk, and strengthen their overall security posture.
Attack paths typically provide adversaries with a route from a non-critical asset to a critical one, but can take various forms depending on the nature of the attack vector exploited and the techniques used by the attacker. Common attack path types include application-based paths, network-based paths, and paths that leverage social engineering tactics, each of which can offer ways for attackers to escalate permissions and compromise assets.
Attack paths can be identified through a variety of methods. However, the most effective way to do so is to combine proactive security processes to maximize visibility and detection. This can involve the utilization of practices such as network mapping, vulnerability scanning, penetration testing, security assessments, network monitoring, and threat intelligence analysis, among others.
Attack paths pose significant risks to organizations as they can enable attackers to access vital assets, including sensitive data. Risks include data breaches, reputational damage, financial losses, compliance violations, and operational disruption.
For best results, organizations should seek to assess attack paths regularly in conjunction with continuous monitoring as part of an ongoing proactive cybersecurity strategy. The exact frequency of such assessments will depend on factors specific to an organization and its industry, such as changes to network infrastructure, system updates, regulatory requirements, or developments in the threat landscape.
