How to create a complete digital asset inventory in 5 practical steps
Lack of visibility into critical digital assets and Shadow IT is a fundamental business problem for any organization. In a world where the digital ecosystem grows increasingly complex, unmanaged complexity introduces… systemic risks.
To address the ‘Defender's Dilemma’ (the defender's dilemma), where attackers only need to strike once while defenders must succeed every time, it is essential to start with the basics: knowing what needs protection. Creating and maintaining a digital asset inventory falls under the ‘Identify’ pillar of the NIST framework (National Institute of Standards and Technology).
Here are 5 practical steps to help you create a complete and effective inventory of your digital assets.
1. Define your attack surface
The first step in creating a complete inventory is understanding what makes up your attack surface.
- Go beyond the obvious: Traditionally, this meant manually listing external assets such as IP ranges, VPN servers or web applications, often recorded in spreadsheets.
- Identify hidden critical assets: It is essential to include assets that are often overlooked or ignored. These include:
- External-facing remote access services and databases.
- Developer accounts on platforms such as Github or Gitlab.
- Staging (preparation) and QA (quality assurance) environments.
- Externally exposed cloud storage (blob storage buckets).
- More esoteric application software or network services exposed to the Internet.
Understanding the attack surface provides the scope and context for penetration testing and vulnerability management efforts.
2. Adopt a continuous discovery and visibility solution
An asset inventory cannot be a static document. The migration of environments to the cloud (multicloud) and the dynamic nature of modern environments require continuous visibility.
- Combat blind spots: The professional Asset Inventory and Risk Assessment service has the expected outcome of reducing blind spots.
- Use converged platforms: Solutions such as Security Command Center (SCC) Premium are vital for continuous risk inventory. Security Command Center Enterprise (SCCE) is the first solution to combine cloud security and enterprise security operations. It uses a continuous risk mechanism that creates a digital twin of your entire multicloud architecture and reveals unknown threats by simulating the role of a sophisticated attacker.
3. Classify critical assets and prioritize them based on risk
Having a list of assets is not enough; you need to know what the attacker is actually looking for. Cyber intelligence should guide every action, focusing efforts on the most critical areas.
- Continuous Risk Mechanism: SCCE provides a prioritized view of data and events across all your clouds. It goes beyond predefined rules, dynamically identifying combinations of risks that can expose high-value resources.
- Attack path identification: SCCE's risk engine provides a detailed understanding of how a sophisticated attacker can move laterally and compromise valuable resources. For example, it can identify when a poor combination of a public IP address, an actively exploited vulnerability and an overly privileged service account exposes sensitive data, such as a BigQuery dataset.
- Data classification: Classifying sensitive data (such as PII, PHI, PCI) using data loss prevention (DLP) tools is a component of the ‘Protect’ pillar that goes hand in hand with asset identification and helps with prioritization.
4. Document context and security posture
The inventory should contain rich detail and context to accelerate triage and incident response.
- Technical and nontechnical details: When collecting data, obtain information about systems (such as the operating system, program affiliation and system purpose) and the functional titles of users who regularly interact with the asset.
- Log and telemetry mapping: Document the types of data being collected (and the volume in gigabytes/day), as well as the data pipeline (agent-based, API, etc.) and SIEM parser configuration. Scattered, uncorrelated logs hinder proactive detection.
- Information transfer: Inventory management should account for relevant information such as the impact of business decisions, active threats or organizational changes in real time.
5. Implement continuous validation and automated governance
Digital assets are in constant ‘drift’ (drift) due to environmental changes and misconfigurations.
- Monitor drift: It is essential to continuously monitor, detect and alert on deviations (drift). SCCE provides posture management, helping ensure that security policies (such as access controls) are applied consistently.
- Automate posture remediation: Security Command Center can detect any policy deviation in real time and allows teams to both detect problems and resolve them through common workflows. For example, if an organization policy changes from enabled to disabled, SCC detects the deviation, enabling rapid action.
- Improve continuously: Intelligence activation activities, including asset identification and vulnerability prioritization, must continuously evolve as the threat landscape changes and business needs develop.
By following these steps, you will transform your asset inventory from a static list into a dynamic risk mitigation tool that strengthens your security posture.
