How to Incorporate Attack Surface Management in Your Security Strategy?


In today’s interconnected digital world, businesses are expected to maintain a proactive stance toward cybersecurity. One increasingly pivotal concept in the realm of information security is Attack Surface Management (ASM). Similar to the physical security goals of reducing access points to a building, ASM aims to limit the avenues that cybercriminals can exploit to gain unauthorized access to your sensitive data. Implementing an effective ASM strategy is vital in comprehensively managing your third-party risk.

Key Concepts of Attack Surface Management

1. Attack Surface Definition: Your attack surface encompasses all the access points and vulnerabilities that a malicious actor could potentially leverage to penetrate your system — this includes all hardware, software, and human aspects.

2. Internal and External Surfaces: Your attack surface is twofold, covering both internal vulnerabilities in your network and external threats from third-party vendors.

3. Attack Surface Reduction: By minimizing these points of exposure, a business can effectively diminish their cybersecurity risk and reliance on countermeasures.

Pros and Cons of Attack Surface Management


– Proactive risk approach: ASM counters threats before they materialize into full-blown attacks, enabling threat prevention rather than just response.
– Comprehensive security: By focusing on surface reduction, business entities can drastically place a bulwark against cyber threats spanning every point of their operation.
– Improved visibility: ASM provides a thorough understanding of your system’s vulnerabilities, enabling better decision-making and risk management.


– Resource-intensive: Implementing a potent ASM strategy demands regular checks, audits, and updates, consuming significant time and manpower.
– Complexity: Given the number of potential points of exposure in a digital environment, full attack surface reduction is a complex, ongoing process.

Best Practices for Attack Surface Management

Routinely Cataloguing Vulnerabilities: By routinely documenting and investigating vulnerabilities in your system, your organization can better mitigate potential threats.
Consistent Patching and Updates: Keep software and hardware systems updated with the latest patches to close off known vulnerabilities.
Utilizing Tools: There are plenty of ASM tools in the market (like TPRM Pro) that automate these processes to ensure continuous monitoring and timely action.

Challenges and Considerations

ASM deals with continuously evolving threats, and maintaining your guard requires perpetual vigilance. Further, the human element in ASM can lead to gaps in security, necessitating comprehensive employee training and awareness programs.

Future Trends

The adoption of ASM is set to grow exponentially, driven by the increasing online threats and regulatory pressure. Additionally, the integration of artificial intelligence and machine learning in ASM tools will boost threat prediction accuracy, enabling smarter and quicker responses to potential vulnerabilities.


Incorporating Attack Surface Management into your security strategy is a critical step in managing third-party risk and ensuring comprehensive cybersecurity. While it comes with its challenges, the potential benefits vastly overshadow the cons.

Like every aspect of cybersecurity, ASM isn’t a one-and-done deal. It’s a continuous and evolving process, well worth the investment to protect your valuable digital assets.
