Asset management in information security involves maintaining an accurate inventory of all hardware, software, data, and cloud resources an organization uses. It ensures all assets are identified, classified, assigned ownership, and protected according to their value and sensitivity.
You cannot protect what you do not know you have — this axiom makes asset management a foundational control for every compliance framework. An effective asset management program maintains a comprehensive inventory that includes physical assets (laptops, servers, mobile devices, networking equipment), software assets (installed applications, SaaS subscriptions, licensed tools), data assets (databases, file shares, cloud storage), and cloud resources (compute instances, storage buckets, serverless functions). Each asset should have an assigned owner, a classification level, and documented security controls. ISO 27001 places strong emphasis on asset management, requiring an asset inventory and acceptable use policies. SOC 2 auditors verify that organizations know what systems are in scope and how they are protected. HIPAA requires covered entities to maintain an inventory of systems that create, receive, maintain, or transmit ePHI. Modern organizations face particular challenges with shadow IT — unauthorized SaaS tools that employees adopt without IT approval. Implementing a Cloud Access Security Broker (CASB) and regular SaaS discovery audits helps maintain inventory accuracy.
Data classification is the process of categorizing data based on its sensitivity level and the impact of unauthorized disclosure. Common tiers include Public, Internal, Confidential, and Restricted, each with corresponding handling and protection requirements.
Vulnerability management is the continuous process of identifying, classifying, prioritizing, remediating, and mitigating security vulnerabilities in systems and software. It includes regular scanning, patch management, and risk-based prioritization.
Change management is the structured process for reviewing, approving, implementing, and documenting changes to IT systems, infrastructure, and applications. It aims to minimize the risk of unintended disruptions while enabling necessary system evolution.
An Information Security Management System (ISMS) is a systematic framework of policies, processes, and controls that an organization implements to manage and reduce information security risks. It encompasses people, processes, and technology in a holistic approach to security governance.
