What is attack surface management?

An attack surface is the sum of all possible security risk exposures, such as known, unknown, and potential vulnerabilities within hardware, software, and networks. Attack surfaces are constantly growing and evolving, making them dynamic and complex. Understanding what your attack surface represents is important, but it’s only the first step. 

Attack surface management (ASM) - also known as attack surface mapping or monitoring - refers to an increasingly popular and highly effective and increasingly popular method of cyber security. Specifically, ASM refers to continuous surveillance of your attack surface and the vulnerabilities that contain, transmit, or process your data. ASM will teach you:

  • what the components of your attack surface are
  • where the attack vectors and exposures are located
  • how to shield your organization from future data breaches and cyber attacks

With the occurrence of breaches increasing (and their severity), careful monitoring of your online environment is vital to surviving in the modern digital climate. Often, your attack surface is larger than you think and any digital asset could potentially be vulnerable, so ASM should be a priority and a basic security measure for all businesses.

What is at stake?

Aside from providing meticulous surveillance of your attack surface, ASM can also help prevent risks such as human error, like phishing or data leaks, and out-of-date software - which can cause basic security lapses to better protect your data from potential threats. 

With ASM you can:

  • Gain real-time visibility of your true attack surface
  • View data in different formats, allowing you to visualize your vulnerabilities and gain a wider and deeper understanding of your digital environment and evaluate risks faced
  • Comply with data protection regulations, such as GDPR
  • Be assured you that your attack surface is examined 24/7, allowing for immediate remediation if a vulnerability or threat is discovered

Reducing your attack surface

A popular security technique is to reduce your attack surface by reviewing your digital footprint and exposing those assets that are necessary for your business to operate. However, although reduction strategies can be beneficial, attackers are still able to locate attack vectors in your external assets, so reducing your attack surface alone will not suffice. 

Instead of just reducing your attack surface and hoping for the best, consider installing a reliable ASM platform that would make life a lot easier. The proactive approach saves precious time, money, and energy while providing assurance of guaranteed and around-the-clock surveillance.

Gain visibility of your true attack surface

Monitoring your internal network alone and endpoint security measures are simply no longer enough to protect your company’s digital network. It is no longer a question of if an attacker will locate an attack vector, but when and how often and easily. With concern growing, we all need to adapt and adjust our security programs to consider a better strategy. 

Of course, there is no omnipotent form of cyber security, but ASM is definitely a very good place to start. Ultimately, a robust and reliable security approach is your best bet for any company’s prosperity and longevity.
