Risk Management
Modern Attack Surface Management for Cloud Teams
Today’s attack surface requires modern processes and security solutions. Explore the tenants of modern attack surface management (ASM) and what Cloud teams need to look for in an ASM solution.
Today’s distributed environment of remote working endpoints, cloud apps and infrastructure, IoT devices and much more, have made securing the attack surface a daunting challenge. The cloud brings an extra layer of uncertainty; assets and resources are spun up and down with minimal—if any—notice. An ESG survey about cloud detection and response (CDR) reported that 42% of respondents believe their existing tools aren’t up to the task of ephemeral cloud attack surfaces.
While many organisations have implemented a cloud security solution like CNAPP, risks persist outside of their cloud environments, and security teams have no way to find, view, and correlate everything across their organisation’s attack surface.
Cloud teams (CCoE, Cloud Security Architects, and others) need to shift to more robust, modern ASM solutions that can combine in-depth cloud security data with other inventory information for a holistic view of risk. This empowers better decision-making, accelerates development, and reduces complexity associated with isolated security tools.
Getting the most value out of modern ASM
Not all solutions are built the same. Many vendors will cover the basic tenants of ASM: discovery, assessment, and mitigation. And while this a great first step, it’s not enough. Securing the cloud requires broad capabilities that enhance Cloud teams decision making to increase efficiency, optimise organisational security strategy, and reduce complexity.
Rapid, continuous attack surface discovery
First, teams need to identify an organisation’s devices, accounts, applications, and cloud assets—both external and internal. This requires total and real-time visibility, which is only possible if the solution integrates with third-party sources and scans across on-premises, cloud, and hybrid cloud environments continuously.
Real-time risk assessment and prioritisation
Next: assessment. Some vendors might only provide point-in-time assessments instead of continuous and contextual evaluations. Cloud teams need a strong ASM solution that goes beyond simple assessment by creating a risk score that enables rapid risk prioritisation against several factors such as likelihood of an attack, possible impact of an outage, and asset criticality. Moreover, a risk score provides a helpful, at-a-glance look at the entire organisation’s security posture that can be leveraged to quickly demonstrate success to a CIO/CTO.
The right solution will combine automated threat and vulnerability scanning, compliance scanning, and global threat intelligence. This provides a single-pane overview of prioritised API-associated risk across multiple cloud accounts, CVEs mapped to container clusters or images, and cloud misconfigurations mapped to compliance frameworks.
Proactive risk remediation and management
Risk prioritisation helps Cloud teams anticipate adversaries faster, leading to speedier mitigation. ASM solutions should surface potential attack paths and leverage AI and ML to synthesise vulnerabilities, risks, security controls, compliance frameworks, and overall posture to provide teams with risk remediation suggestions. This will accelerate response actions and mitigate risk before the incident is realised. Bonus points if the solution can orchestrate and automate risk response across the enterprise.
The platform approach
According to a Trend Micro study, 89% of respondents have plans to consolidate security products or switch to a platform in the near future. And for good reason: a platform approach is essential to increasing efficiencies by reducing alert overload from disconnected security solutions. Full understanding and context of threats opposed to limited, piecemealed data insights, empower security teams to make risk-based decisions.
Trend Vision One™ Attack Surface Risk Management (ASRM), supported by Trend Micro’s industry-leading research, is a cornerstone solution within the Trend Vision One™ platform. ASRM empowers security leaders to consistently uncover, identify, and prioritise organisational risks, enabling them to swiftly take data-driven actions to proactively mitigate risk and reduce their attack surface.
The Trend Vision One platform is built to unify policy management, ASRM, and detection and response capabilities across the enterprise. The platform’s native-first, hybrid approach to XDR and ASM benefits security teams by delivering richer activity telemetry—not just detection data—across security layers with full context and understanding. This enables teams to contextualise risk and reduce the likelihood of attacks—while reducing false positives and noise within the environment continuously and proactively.
XDR for cloud, or CDR, correlates threat signals from cloud, multi- and hybrid-cloud, and on-premises environments to ensure alerts are prioritised and escalated against an ever-changing threat landscape. It enables teams to scale threat hunting and investigation by visualising the full attack story using interactive graphs, MITRE ATT&CK™ mapping, and simplified search techniques.
Furthermore, Trend Vision One can automate and orchestrate workflows to enhance and augment security analysts’ efforts by speeding up standard operation procedures, removing manual steps, and enabling quick analysis and action such as vulnerability patching. According to ESG, 51% of organisations have improved threat detection as a result of automating security processes via playbooks.
