The Essential Guide to Automated Attack Surface Management
In today's digital environment, securing online assets against cyber threats is crucial. Automated attack surface management emerges as a key strategy for protecting these assets efficiently. This method not only boosts security process efficiency but also significantly contributes to digital risk reduction.
Organizations are increasingly turning to cybersecurity automation tools to stay ahead of potential security breaches. These tools are essential for an effective automated vulnerability assessment, allowing for the quick identification and remediation of security vulnerabilities. By integrating continuous security monitoring, businesses can ensure a robust defense mechanism that is both proactive and resilient.
What is Attack Surface Management?
Understanding attack surface management is crucial for any organization aiming to fortify its cybersecurity posture. At its core, the attack surface of an organization encompasses all the potential points through which an unauthorized user might attempt to enter or extract data from the environment.
This includes everything from exposed endpoints, unpatched software, open ports, and misconfigured services to more nuanced elements like cloud storage permissions and third-party vendor vulnerabilities.
What is an Attack Surface?
An attack surface is essentially the sum total of all possible entry points or vulnerabilities that an attacker could exploit to gain unauthorized access to a system or network. It's a dynamic entity, constantly changing as new technologies are adopted, new software is developed, and networks expand.
Components of an attack surface can broadly be categorized into physical, digital, and human elements. Physical components might include any hardware or devices that connect to your network. Digital components encompass software, applications, databases, and web interfaces. Human elements refer to the people who interact with your systems, whose actions can inadvertently expand your attack surface through errors or oversights.
Challenges in Managing Attack Surfaces
The primary challenge in managing attack surfaces stems from their inherently dynamic nature. As organizations grow and evolve, so too do their digital assets. New applications are deployed, old systems are updated or replaced, and user behaviors change. Each of these changes can potentially introduce new vulnerabilities or expand the attack surface, making it increasingly difficult to secure.
Moreover, the complexity of modern IT environments adds another layer of difficulty. With the adoption of cloud services, the proliferation of IoT devices, and the increasing reliance on mobile technology, the boundaries of organizational networks are more blurred than ever. This complexity makes it challenging to maintain visibility over every component of the attack surface, let alone secure them against potential threats.

Why Attack Surface Management is Integral for Your Exposure Management Strategy
Attack surface management (ASM) addresses these challenges by providing organizations with the tools and processes needed to gain comprehensive, continuous visibility into their assets.
This visibility is crucial for understanding not just what assets you have, but also how they are being used and where potential vulnerabilities or security issues might exist. From both a user and an attacker's perspective, ASM offers a way to map out the entire landscape of potential entry points.
By enabling security teams to identify, assess, and prioritize these vulnerabilities for remediation, ASM plays a pivotal role in staying one step ahead of attackers. It's not just about finding weaknesses; it's about understanding the entire ecosystem of your digital assets and how they interact.
This comprehensive approach is what makes attack surface management an indispensable part of any effective cybersecurity strategy, ensuring that organizations can adapt to the ever-changing threat landscape with agility and confidence.
The Limits of Manual Attack Surface Management: A Time and Efficiency Analysis
The capacity of security teams to effectively manage attack surface risks without the aid of automated processes is increasingly doubtful. A 2023 survey involving IT and cybersecurity experts revealed a striking figure: approximately 72% of respondents acknowledged that just the task of discovering their attack surface demands over 40 hours of manpower.
This figure doesn't even account for the additional time required to analyze the findings, prioritize next steps, and mitigate identified risks. Furthermore, about 62% of organizations have observed their attack surface expanding in the last two years.
The necessity for automated tools in keeping up with the pace of attack surface risks is becoming more apparent. Here’s a closer look at why manual management of attack surfaces is becoming untenable.
The High Cost of Manual Management
Attempting to stay ahead of the growth in an enterprise's attack surface through manual or disjointed processes is becoming increasingly impractical. Every new service installation or asset deployment connected to a network or the internet at large contributes to the expansion of an organization's attack surface.
Many of these assets suffer from poor configuration right from the start, while others, such as unauthorized SaaS tools and personal accounts, might not even be on the IT team's radar. It's estimated that the average company's network hosts about 30% more assets than its security team is aware of.
Even assets that are known and properly configured can become vulnerabilities, for instance, when certificates expire or patches are not applied in time. The reality is that most organizations have hundreds of assets that could potentially be exploited in a cyberattack.
A 2022 study of Fortune 500 companies highlighted this vulnerability, showing that the average organization is exposed to around 476 common vulnerabilities and exposures (CVEs) within its external attack surface. Cybercriminals exploit these vulnerabilities by scanning for assets with CVEs, often successfully.
Security teams strive to preempt these threat actors by identifying potential vulnerabilities. This might involve analyzing certificate transparency logs or employing brute force methods to uncover connected domains. However, the race against cybercriminals is also a race against time:
A hacker can identify an exploitable vulnerability within just ten hours. Within five hours of discovery, that vulnerability is likely to be exploited, granting the hacker access to the network. It takes only about an hour and a half for the hacker to begin moving laterally within the network. These timelines, based on the activities of both ethical and criminal hackers, underscore the vulnerability of organizations from the perspective of an attacker.
In a scenario where a threat actor can scan, compromise, and navigate an organization's network in roughly 16 hours, the challenge for security teams becomes starkly evident. The question arises: Can a team identify and decide on remediation strategies for evolving network vulnerabilities within such a narrow window?
And can they do this continuously? With the average organization taking upwards of 80 hours just to map out their attack surface—and only 26% engaging in continuous management—the reliance on fragmented tools, spreadsheets, and manual methodologies is proving inadequate for the task of managing expanding attack surfaces.
Streamlining Attack Surface Management with Automation in Four Essential Steps
The integration of automation into attack surface management significantly enhances the speed and efficiency with which security teams can identify and mitigate risks. The primary advantage of automation in cybersecurity lies in its capacity to sift through extensive data sets swiftly, enabling security teams to execute informed, automated responses promptly.
While traditional methods of identifying and understanding an attack surface can be time-consuming, leveraging an automated attack surface management (ASM) solution can provide immediate, actionable insights.
Here's a breakdown of the four critical steps to automating attack surface management, incorporating the earlier mentioned SEO keywords:
1. Asset Discovery
The first step involves the automated identification of internet-facing hardware, software, and cloud assets that could potentially serve as entry points for cyber threats. By employing automated cybersecurity automation tools, the process of evaluating whether an asset is network-connected is expedited, enhancing digital risk reduction.
