Attack Surface Reduction

Attack Surface Reduction

Your attack surface is constantly changing. M&A transactions. New web servers. Onboarding new vendors. Unsanctioned cloud development. These and many other cases make it easy for Internet-connected assets to get added to your network without your corporate IT and security teams knowing. You can’t protect what you don’t know about, and all too often your “unknowns” become potential attack vectors for adversaries.

Most cyber attacks originate from external attack vectors

Attackers can use machine-speed attacks to discover and breach unknown assets in minutes. Many high-profile breaches in recent years happened through exposures that were not visible to the organization. This can result in significant damage to your brand reputation, business interruption, and sensitive data loss.

Know your exposures

Existing security solutions fall short when it comes to finding unmonitored and unsanctioned assets. Companies often focus on protecting known assets on the network rather than on uncovering the unknowns. They rely on internally generated and self-reported Master IP Address Lists that are incomplete or on Internet scanning tools that require you already know what you’re looking for.

Assets that can expose you to attacks include:

  • Internet-connected servers with responsive services
  • Invalid or expired certificates
  • Untracked domains
  • Unsanctioned cloud assets
  • Unknown or misidentified IP addresses and ranges

When companies don’t have a plan to identify and govern these unknown assets, they leave exposures on the public Internet that are easy for an attacker to exploit.
