An Overview Of Attack Surfaces In Cybersecurity
By Tom Seest
Using FullHunt to identify Internet-facing assets is a great way to prevent cyberattacks. Its cloud-distributed engines discover external attack surfaces in minutes, and its Assets Monitor continuously profiles and identifies changes in assets. In addition, its Eagle service automatically scans external assets for security risks and vulnerabilities.

In order to discover attack surfaces and find vulnerabilities, Security Researchers use DNS reconnaissance tools. These tools provide detailed information on networks, such as host details, email addresses, and file formats. They also contain a database of attack surfaces from around the Internet. The FullHunt application is an example of such a tool and can identify attack surfaces on a network. Once you have identified these attack surfaces, you can continuously scan them for vulnerabilities and threats.

DNS reconnaissance is a valuable tool for attackers. These queries can help them build a map of a target network and implement various attacks. DNS queries can also indicate if a network is compromised. Common signs of a compromised network include large numbers of PTR, SOA, and AXFER queries, forward DNS lookups of nonexistent subdomains in the root domain, and data theft. In addition, DNS tunneling may be used for malware or command execution into a target network.
Security Researchers use DNS reconnaissance applications to monitor target networks for vulnerabilities. DNS reconnaissance software provides information about target networks, including email addresses, hosts, and formats. Because DNS is an open protocol, adversaries may exploit this system to conduct malicious activities. They may use DNS to download malware, communicate with command and control servers, and move data out of the network. Therefore, it is essential to monitor DNS to protect networks from these threats.

The FullHunt Exploit Database and Security Trails are powerful tools to help protect a company’s online assets from attack. These tools use an exhaustive database of publicly available exploits to identify potential vulnerabilities. Both tools use cloud-distributed engines to discover the external attack surface in minutes. FullHunt Assets Monitor continuously profiles and analyzes changes in assets, and FullHunt Eagle automatically scans external assets for security risks and vulnerabilities.
An attack surface is a system’s total number of points of access for unauthorized users. It includes endpoints, vulnerabilities, and other security controls. The larger the system, the larger the attack surface. Modern businesses have large and complex attack surfaces with a variety of users, devices, web applications, and network nodes. Often, it is difficult for IT managers to know all of the risks.
