Cybersecurity asset management (CSAM) is a process that plays a crucial role in safeguarding organizations and their assets from security threats. It involves continuously discovering, inventorying, monitoring, managing, and tracking an organization’s assets to determine what they do and identify any gaps in cybersecurity protections that need to be addressed.
CSAM, a subset of IT asset management (ITAM), offers real-time visibility to security operations (SecOps) teams so they can optimize their resources and maintain a proactive, risk-based security program. It enables them to respond quickly to security incidents and is an essential component of security frameworks such as the NIST Cybersecurity Framework and Center for Internet Security Critical Security Controls.
Assets that fall within the scope of CSAM include traditional endpoints like desktops, laptops, and mobile devices, network infrastructure including cloud assets, IoT sensors, virtual and hardware appliances, operating systems, IP-connected operational technology (OT) systems, users, and physical infrastructure such as office buildings and data centers.
Managing assets in today’s enterprise environments presents numerous challenges. Employees, contractors, and service providers are scattered across different locations and use a variety of devices and services, including shadow IT. Fully virtualized assets often reside in public clouds, increasing complexity. The convergence of IT and operational technology (OT) leads to a surge in the number and types of connected devices, many of which lack adequate security measures. Data and appliances are used and stored across multiple geographic regions, and virtual environments consist of services, microservices, virtual machines, and containers that can have short lifespans.
One key aspect of CSAM is visibility. Securing assets requires knowing what they are, but with the increasing number and types of assets, manual tracking becomes challenging. SecOps teams cannot rely on spreadsheets or databases alone to keep track of assets in their environment. CSAM addresses this issue and provides a solution for SecOps teams.
CSAM utilizes a variety of tools and processes to discover assets on a network, investigate their security controls, and ensure they are properly secured. It includes device discovery and inventory, vulnerability management, network and security monitoring, risk analysis and assessment, incident response, and policy enforcement. CSAM can also help organizations maintain regulatory compliance.
While existing tools can support CSAM, their siloed nature often makes it difficult to correlate data effectively. Many vendors now offer dedicated CSAM platforms that aim to streamline the process.
CSAM follows a three-step cycle: asset discovery and inventory, gap identification, and automated response. Tools scan the network to create an asset inventory, including details like hardware or software version, manufacturer, location, access permissions, and compliance regulations. CSAM also identifies security coverage gaps and recommends measures to remediate them, using automation to deploy cybersecurity resources as needed. The cycle repeats to ensure all information security gaps are addressed.
The benefits of CSAM are significant. It provides a real-time view of an organization’s security posture and offers visibility across the entire network. It enables rapid assessment of assets and pinpointing of security coverage gaps, down to the application and service levels. Continuous asset discovery ensures an accurate inventory, and CSAM helps determine which cybersecurity tools are active on the network and how they are used. It streamlines the process of identifying the most effective tools and where to deploy them. Additionally, CSAM can assist with asset catalogs, end-of-life management, shadow IT discovery, and patch management.
CSAM differs from ITAM in its focus and purpose. ITAM primarily addresses business needs such as software licensing and support contracts, while CSAM concentrates on understanding assets’ functionality on the network, their current protections, and the need for additional protection measures.
In conclusion, CSAM is crucial for organizations to optimize their cybersecurity strategies and protect their assets from security threats. It offers real-time visibility, enables quick response to security incidents, and aligns with key security frameworks. Overcoming the challenges of managing assets in modern enterprise environments, CSAM ensures organizations have a comprehensive understanding of their assets and their cybersecurity protections while aiding in regulatory compliance and optimizing resource usage.
