Web Administrators must only use encrypted connections for Document Root directory uploads. |
Logging in to a web server via an unencrypted protocol or service, to upload documents to the web site, is a risk if proper encryption is not utilized to protect the data being transmitted. An encrypted protocol or service must be used for remote access to web administration tasks. |

The web client account access to the content and scripts directories must be limited to read and execute. |
Excessive permissions for the anonymous web user account are one of the most common faults contributing to the compromise of a web server. If this user is able to upload and execute files on the web server, the organization or owner of the server will no longer have control of... |

Web server administration must be performed over a secure path or at the local console. |
Logging into a web server remotely using an unencrypted protocol or service when performing updates and maintenance is a major risk. Data, such as user account, is transmitted in plaintext and can easily be compromised. When performing remote administrative tasks, a protocol or service that encrypts the communication channel must... |

The LogLevel directive must be enabled. |
The server error logs are invaluable because they can also be used to identify potential problems and enable proactive remediation. Log data can reveal anomalous behavior such as “not found” or “unauthorized” errors that may be an evidence of attack attempts. Failure to enable error logging can significantly reduce the... |

Public web servers must use TLS if authentication is required. |
Transport Layer Security (TLS) is optional for a public web server. However, if authentication is being performed, then the use of the TLS protocol is required.
Without the use of TLS, the authentication data would be transmitted unencrypted and would become vulnerable to disclosure. Using TLS along with DoD PKI... |

Access to the web server log files must be restricted to Administrators, the user assigned to run the web server software, Web Manager, and Auditors. |
A major tool in exploring the web site use, attempted use, unusual conditions and problems are the access and error logs. In the event of a security incident, these logs can provide the SA and Web Manager with valuable information. Because of the information that is captured in the logs,... |

Log file data must contain required data elements. |
The use of log files is a critical component of the operation of the Information Systems (IS) used within the DoD, and they can provide invaluable assistance with regard to damage assessment, causation, and the recovery of both affected components and data. They may be used to monitor accidental or... |

Private web servers must require certificates issued from a DoD-authorized Certificate Authority. |
Web sites requiring authentication within the DoD must utilize PKI as an authentication mechanism for web users. Information systems residing behind web servers requiring authorization based on individual identity must use the identity provided by certificate-based authentication to support access control decisions. |

The web document (home) directory must be in a separate partition from the web server’s system files. |
Application partitioning enables an additional security measure by securing user traffic under one security context, while managing system and application files under another. Web content is accessible to an anonymous web user. For such an account to have access to system files of any type is a major security risk... |

PERL scripts must use the TAINT option. |
PERL (Practical Extraction and Report Language) is an interpreted language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information. The language is often used in shell scripting and is intended to be practical, easy to use, and efficient means of... |

Anonymous FTP user access to interactive scripts must be prohibited. |
The directories containing the CGI scripts, such as PERL, must not be accessible to anonymous users via FTP. This applies to all directories that contain scripts that can dynamically produce web pages in an interactive manner (i.e., scripts based upon user-provided input). Such scripts contain information that could be used... |

A private web server must have a valid DoD server certificate. |
This check verifies that DoD is a hosted web site's CA. The certificate is actually a DoD-issued server certificate used by the organization being reviewed. This is used to verify the authenticity of the web site to the user. If the certificate is not for the server (Certificate belongs to),... |

A private web server must utilize an approved TLS version. |
Transport Layer Security (TLS) encryption is a required security setting for a private web server. Encryption of private information is essential to ensuring data confidentiality. If private information is not encrypted, it can be intercepted and easily read by an unauthorized party. A private web server must use a FIPS... |

A web site must not contain a robots.txt file. |
Search engines are constantly at work on the Internet. Search engines are augmented by agents, often referred to as spiders or bots, which endeavor to capture and catalog web-site content. In turn, these search engines make the content they obtain and catalog available to any public web user.

Web content directories must not be anonymously shared. |
Sharing of web server content is a security risk when a web server is involved. Users accessing the share anonymously could experience privileged access to the content of such directories.
