What is External Attack Surface Management?


Your online attack surface includes more than just your third-party vendors.

Every asset your customers and employees access when interacting with your company online makes up your
External Attack Surface.

These assets may be owned by your organization, owned and operated by a third-party vendor, or exist somewhere in your long chain of Nth-degree vendors. Attack surface visibility is the key to detecting any anomalies in your digital supply chain.

Third-Party Dependencies Weaken
Your Cyber Security Defenses

One web page typically has dozens, if not hundreds, of resource dependencies pulled from third-party hosts.

HTML or JavaScript Dependencies

Dependencies create a sprawling attack surface, with the most prevalent connections created by HTML or JavaScript. These can be found in HTML image import tags, script tags, CSS, and others that pull information from third-party vendors and websites. Cyberpion provides dependency discovery and thorough attack surface visibility.

Redirects

Redirects impart a sense of trust onto the redirected sites and need to be monitored and managed. Rather than asking your security team to manually crawl each page on your site and find every redirect, Cyberpion’s attack surface visibility shows all the redirects across your online presence on a single dashboard.

External Attack Surface Visibility: Beyond Third-Party Connections

In many cases, resource dependencies form long chains. The cloud infrastructure of the authoritative name server of a third-party email server could be hijacked, which has the same result as taking over the mail server directly. A third-party script will reference a fourth-party script. That fourth party may in turn reference a fifth party, and it continues on and on.

Every connected asset within your sprawling attack surface could be a potential vulnerability.

Growth In Attacks Via Third-Parties

Third-Party Attacks Continue to Grow

Attacks will continue to increase as malicious actors discover that this path of least resistance offers the best return on their investment. By taking control of a single third-party asset, attackers can leverage that asset to target all customers through direct or indirect connections to that asset. Because this access comes through a third-party vendor or partner, the attacker avoids an organization’s sophisticated firewalls, logs, virus scanners, or other detection tools.

Infamous exploits of vulnerabilities include Magecart style attacks and cloud-based asset abuse. Both start from vulnerabilities like third-party JavaScript inclusions or poor cloud configuration.

But that’s only the tip of the iceberg in terms of possible attacks and exploits. Nearly 50% of all cyber attacks are initiated from an organization’s digital supply chain.

Cyberpion enables security teams to guard every component of their attack surface with attack surface visibility, continuous vulnerability assessment, and active protection.
