Business operations increasingly rely on cloud applications and connected systems and so the need for modern security measures has never been greater. Your business’s ever-evolving attack surface constantly faces sophisticated and complex threat vectors.
Understanding your organization’s attack surface is becoming increasingly important, especially in the age of digital transformation and hybrid work environments. The potential points of entry that attackers use to gain access and launch attacks is changing — digital asset proliferation and unstructured data continually increases your organization’s overall cyber risk.
A holistic combination of attack surface management (leveraging people, processes, and technology to manage and mitigate risk), attack surface strategy (the process you rely on to understand your business’s relevant use cases), and attack surface assessment (tools used to help rank and prioritize use cases) ensures that your attack surface is addressed through a comprehensive approach.
Legacy technologies were designed to address specific and often siloed threats. Traditional security stacks used technologies that required specific skillsets to operate and understand. A modern security stack considers the organization’s overall attack surface in a cohesive and efficient way.
Attack surface management (ASM) addresses the overall attack surface through three lenses: internal assets focus (cyber asset attack surface management, or CAASM), enterprise brand protection and compliance (digital risk protection services, or DRPS), and external assets focus (external attack surface management, or EASM).
Of these three pillars, CAASM offers some internal and external overlap. Depending on your business’s use cases, CAASM offers an ideal starting point as it addresses shared use cases across ASM pillars include asset management, remediation prioritization, data loss prevention strategy, and asset and data discovery.
