The Growing Attack Surface: Concerns, Cloud Migration, IoT Devices, and More

The Growing Attack Surface: Why It’s a Concern

The attack surface is continuously expanding, outpacing the ability of security teams to keep up. In order to effectively protect your organization, it is vital to understand what is exposed and where attackers are likely to strike. With the prevalence of cloud migration and the subsequent increase in internal and external targets, managing your attack surface and prioritizing threats from an attacker’s perspective has become more critical than ever.

The Impact of Cloud Migration

Cloud migration has significantly contributed to the growth of the attack surface. As organizations adopt cloud-based solutions and move their infrastructure and data to the cloud, new entry points for attackers are created. Cloud environments introduce a myriad of potential vulnerabilities, ranging from misconfigurations to inadequate access controls, increasing the likelihood of a successful attack.

The Proliferation of IoT Devices

Another factor contributing to the expanding attack surface is the proliferation of Internet of Things (IoT) devices. These devices, from smart home appliances to industrial sensors, are connected to the internet and are often inadequately secured. Attackers can exploit these insecure devices as entry points to infiltrate networks and compromise sensitive information. With billions of IoT devices and a lack of standardized security practices, the attack surface continues to grow.

Expanding Network Perimeters

The traditional network perimeter is no longer sufficient to protect against modern threats. With the rise of remote work, cloud services, and mobile devices, the boundaries of a network have become blurred. Organizations now have a distributed workforce accessing resources from various locations and devices, expanding the attack surface. Attackers can exploit weak points in these extended perimeters to gain unauthorized access and compromise systems.

Third-Party Dependencies

Organizations often rely on third-party vendors and partners to deliver various services and solutions. While this provides benefits in terms of efficiency and specialization, it also introduces additional attack vectors. Attackers can target vulnerabilities in third-party systems and use them as a gateway to gain access to an organization’s networks and data. Managing these dependencies and ensuring the security of third-party systems is crucial in mitigating risks and reducing the attack surface.


The attack surface is expanding at a rapid pace, surpassing the capabilities of security teams. Key factors contributing to this growth include the widespread adoption of cloud migration, the proliferation of insecure IoT devices, the expanding network perimeters due to remote work and mobile devices, and the reliance on third-party vendors and partners. To effectively protect against modern threats, organizations must prioritize threats and manage their attack surface from an attacker’s perspective.
