Attack Path Analysis: a practical method to reduce risk

Attack Path Analysis: gestione e mitigazione dei rischi

Attack path analysis helps to understand how an attacker could reach critical assets through a chain of real-world actions, rather than just through isolated vulnerabilities. In this in-depth look, we examine the differences, the operational method, and how to translate the analysis into remediation priorities. For the complete strategic framework, you can also consult Attack Path Management for corporate security and Attack Path Management with MITRE ATT&CK.

What is an attack path

An attack path is a sequence of steps that an attacker can exploit to move laterally and reach sensitive resources. The path may include privilege escalation, abuse of compromised accounts, unnecessary trust relationships, and misconfigurations. Mapping these steps allows you to identify the points at which to break the chain before it produces concrete impacts.

Among the most frequent scenarios are MITRE ATT&CK techniques such as T1098, T1190, and T1574, which can be represented on Active Directory identities, Azure AD, IAM, and core assets.

Difference between attack path and attack graph

The attack path describes a specific route; the attack graph represents the set of all possible paths in an environment. In the graph, nodes correspond to identities, hosts, groups, and roles, while edges show operational relationships such as privileges, sessions, and memberships. This view makes it clearer where lateral movement risks are concentrated.

Operational method of attack path analysis

An effective process follows four phases: infrastructure data collection, graph construction, identification of critical paths, and prioritization of interventions. The output should not remain theoretical: it must be integrated into security processes to guide remediation and continuous monitoring.

In practice, the value increases when the analysis interacts with Threat Intelligence & Digital Risk Protection services and the Security Operation Center, so as to link exposure, detection, and response. Supporting this with a structured vulnerability management service also allows you to keep track of the vulnerabilities that fuel compromise paths, updating priorities as the infrastructure changes.

Output and remediation priorities

The most useful results are: a list of high-impact paths, critical nodes to fix first, and an estimate of residual risk after each intervention. This approach helps to avoid scattered backlogs and to focus work on the actions that most rapidly reduce the attack surface.

The identity component remains central: excessive privileges, ungoverned service accounts, and weak IAM configurations often enable the most dangerous steps in compromise paths.

Continuous integration into security processes

When attack path analysis becomes continuous, it is no longer a one-time exercise but an operational capability. The organization can update priorities and controls as the infrastructure changes, reducing the time between discovery, decision, and remediation.

To transform analysis into business value, it can be useful to integrate governance and operations with a Virtual CISO and Vulnerability Assessment, supporting reporting with evidence from Research and case studies.

FAQ

  • Why link MITRE ATT&CK to attack graphs?
  • Because it makes the impact of techniques on real paths measurable and helps prioritize remediation and controls.
  • When is a dynamic graph needed?
  • When identities, privileges, and workloads change often: in that context, a static view quickly loses value.
  • How to transform analysis into operational actions?
  • Define critical paths, assign owners and remediation SLAs, then verify the reduction of residual risk over time.
