The Role of Attack Surface Management (ASM) in Cybersecurity
Why Attack Surface Management is Integral for Your Exposure Management Strategy
Your modern attack surface consists of all the potential points of contact an attacker may attempt to access within your IT environment. Attack surface management (ASM) is a process that enables your organization to get comprehensive visibility automatically and continuously into your assets so you're always aware of what you have, how they're being used and where they may have any vulnerabilities or security issues—from a user and attacker's point of view. Attack surface management enables your security teams to seek out security issues, prioritize remediation, and stay one step ahead of attackers.
In this knowledgebase, we’ll help you better understand the role of attack surface management as a cybersecurity best practice.

Como proteger governos municipais e estaduais contra ransomware
Ransomware attacks are on the rise. Attack methods are more complex, and cybercriminals are more resourceful. No longer are threat actors looking only to gain access to your network through an exploit. Attacks today can spread malware across your entire enterprise. Attackers are banking on that they can move laterally undetected long before you realize they’re there. That’s why your organization needs a strong, proactive cybersecurity defense—especially if you’re a government agency. Any device, application, operating system or network is at risk, and you can’t stop these threats if you don’t know where they are. A proactive defense begins with insight into all of your assets and security weaknesses, so you can predict where you have the greatest cyber exposures and then prioritize how you’ll address them.
With Tenable, you can defend your organization against ransomware attacks by finding and addressing flaws before attackers can access them.
Attack Surface Monitoring Insight
Don’t Ignore Attack Surface Management
As your organization embraces more remote work, distributed computing, IoT deployments and cloud adoption, your attack surface grows. As such, you can no longer ignore attack surface management as part of your exposure management strategy. It’s one of the top six things in cybersecurity that needs your attention today. In this Cybersecurity Snapshot, see what the other five hot topics are and explore why ignoring attack surface management now can leave your organization in peril.
Finding the 'Unknown Unknowns' Across Your Entire Attack Surface
If your organization doesn’t have insight into all of your assets, vulnerabilities, misconfigurations and security issues, you can’t protect them. These “unknown unknowns” often keep security teams awake at night. Without insight into all of your cyber exposures, you’re leaving doors open for attackers to step right through, all while increasing your cyber risks.
These “unknown unknowns” are often hidden in your assets with internet-facing connections. When these assets are in a public space—especially when you don’t know about them—it creates more opportunities for attackers looking for quick and easy exploits.
With an attack surface management strategy, your organization can get to the heart of this issue by continuously scanning and monitoring all of your public-facing assets. With this information, you can have clear visibility into your assets, no matter where they are, turning those unknowns into the known so you can address them.

How can we automatically scan all externally facing services on AWS?
We have AWS connector configured, and this shows all our EC2 instances and we're able to use this to scan private instances within our VPC. However, what we'd like to do is automatically scan all public-facing IP addresses in AWS on a continuous basis… Is this possible with Tenable? How do other people monitor the external attack surface?Leia mais
Close your Cyber Exposure Gap and Protect Your Attack Surface
Networks and attack surfaces are changing fast. Today, there’s so much more than servers, network devices and endpoints. Now you’re responsible for securing everything from cloud platforms and application containers to Internet of Things (IoT) devices, and perhaps operational technology (OT) systems. How can you manage it all?Leia mais
Compare Vulnerabilities Between Hosts to Determine Elevated Risk Levels
We have multiple servers going live in our org, and all report multiple informational-level weaknesses. While eliminating each would not be practical, the combination of all weaknesses existing together may allow a bad guy to gather more data of the potential attack surface. I'm looking for a plugin or scan strategy that can identify and report such weaknesses...Leia mais

Proactively Address and Manage Cyber Risks with Tenable One
Attack surfaces are rapidly expanding and as such our threat landscape is constantly evolving. Many organizations, especially those who rapidly spun up new technologies and services during the pandemic may not even know about all of the assets across their organization. Some of these tools were put into use with limited security controls, and in worst cases, with no controls at all.
Without insight into your entire attack surface, your organization faces increased cyber risk. So, how do your teams get that insight they need to conduct asset inventories and understand and prioritize vulnerability management for your most critical business services?
Tenable One empowers your security teams to proactively seek out likely attacks with a single, unified view of your attack surface. Within one platform, your teams can see all of your assets and their associated vulnerabilities on-prem and in the cloud. This enables them to better predict the consequences of an attack so they can prioritize remediation with actionable results that meet your organization’s specific needs.
