Website Control Files
In cybersecurity, Website Control Files are publicly accessible text files that provide instructions and information to external entities interacting with a website, primarily focusing on security and search engine crawling. These files include:
robots.txt: This file guides search engine crawlers on which parts of the website to index and which to avoid. It helps manage how search engines interact with the site's content but can also inadvertently reveal information about potentially sensitive directories or hidden resources.
security.txt: This file provides essential information for security researchers to report vulnerabilities responsibly. It typically includes contact information, security policy details, preferred communication channels, and encryption keys for secure communication.
Key aspects of Website Control Files in cybersecurity:
Passive Reconnaissance: Analyzing these files is a form of passive reconnaissance, providing valuable insights into a website's structure, security practices, and potential vulnerabilities without actively exploiting any systems.
Attack Surface Management: robots.txt can reveal clues about the website's attack surface, helping security professionals identify potential areas of concern—security.txt aids in managing the vulnerability reporting process.
Digital Risk Protection: security.txt facilitates responsible disclosure, reducing the risk of data leaks and brand damage. It also provides contact information for reporting security incidents, enabling faster response times.
Security Posture Assessment: The presence and content of these files offer insights into an organization's security practices and maturity.
By understanding and analyzing Website Control Files, cybersecurity professionals can gain valuable intelligence, improve security assessments, and enhance their ability to manage risks and protect digital assets.
ThreatNG can help with robots.txt and security.txt files in the context of cybersecurity in several ways:
External Discovery: ThreatNG can discover the presence of robots.txt and security.txt files on a website. This can identify potential security risks, such as pages blocked from search engines that may contain sensitive information.
External Assessment: ThreatNG can assess the security of robots.txt and security.txt files by checking for common misconfigurations and vulnerabilities. For example, it can check if the robots.txt file is blocking access to sensitive pages or if the security.txt file is missing important contact information.
Reporting: ThreatNG can generate reports on the security of robots.txt and security.txt files. These reports can be used to identify and remediate security risks.
Continuous Monitoring: ThreatNG can continuously monitor robots.txt and security.txt files for changes. This can help to identify potential security risks that may be introduced over time.
Investigation Modules: ThreatNG's investigation modules can be used to investigate potential security risks associated with robots.txt and security.txt files. For example, the Domain Intelligence module can identify a domain's owner and the technologies used on the website. This information can be used to assess the risk of a potential attack.
Intelligence Repositories: ThreatNG's intelligence repositories can be used to identify known vulnerabilities in robots.txt and security.txt files. This information can be used to assess the risk of a potential attack and to remediate the vulnerability.
Work with Complementary Solutions: ThreatNG can work with complementary solutions, such as web application firewalls (WAFs) and security information and event management (SIEM) systems, to provide a comprehensive security solution. For example, ThreatNG can be used to identify potential security risks, and then a WAF can be used to block attacks that exploit those risks.
Here are some examples of how ThreatNG can help with robots.txt and security.txt files:
ThreatNG can discover a robots.txt file blocking access to a sensitive page, such as a login page. This could indicate that the website is trying to hide the login page from search engines, making it more difficult for attackers to find. However, if the login page is not secured correctly, it could still be vulnerable to attack. ThreatNG can help to identify this risk and recommend remediation steps.
ThreatNG can discover a security.txt file missing important contact information, such as an email address or phone number. This could make it difficult for security researchers to report vulnerabilities to the website owner. ThreatNG can help to identify this risk and recommend remediation steps.
ThreatNG can continuously monitor a robots.txt file for changes. This could help to identify potential security risks that may be introduced over time, such as a change that blocks access to a sensitive page. ThreatNG can help to identify this risk and recommend remediation steps.
ThreatNG's investigation modules can be used to investigate potential security risks associated with robots.txt and security.txt files.

ThreatNG's intelligence repositories can be used to identify known vulnerabilities in robots.txt and security.txt files. This information can be used to assess the risk of a potential attack and to remediate the vulnerability.
Here are some examples of ThreatNG working with complementary solutions:
ThreatNG can be used to identify potential security risks, and then a WAF can be used to block attacks that exploit those risks. For example, ThreatNG can discover a robots.txt file blocking access to a sensitive page. The WAF can then be configured to block access to that page.
ThreatNG can identify potential security risks, and then a SIEM system can monitor attacks that exploit those risks. For example, ThreatNG can discover a security.txt file missing important contact information. The SIEM system can then be configured to generate an alert if it detects an attack that exploits this vulnerability.
ThreatNG is a powerful tool that can improve the security of robots.txt and security.txt files. By working with complementary solutions, ThreatNG can provide a comprehensive security solution for websites.
