How to Configure Web Proxy

Summary:

This document provides detailed instructions on how to configure Carbon Black (Cb) to use a web proxy for communication with both Cb Alliance and Yum repositories. When network security policies require traffic filtering through a web proxy, following these steps will help secure the connection: 1. **Configure Carbon Black Alliance Proxy:** - Edit the `/etc/cb/cb.conf` file to uncomment lines specifying the proxy server for accessing Cb Alliance. Replace IP or DNS with the proxy's details and configure authentication if required. This includes setting the type (basic or ntlm), username (with optional domain), and password options. The password can be either plaintext or encrypted. - Restart `cb-enterprise` after making changes, adjusting commands for both clustered and non-clustered environments. 2. **Configure Yum Repository Proxy:** - Edit the `/etc/yum.conf` file to add proxy settings using the same IP or DNS name as the Cb Alliance proxy server. Configure authentication by adding `proxy_username` and `proxy_password` if necessary. 3. **Generate Encrypted Password:** - Use the script `/usr/share/cb/cbpasswd --encrypt` to convert plaintext passwords into encrypted format, ensuring secure handling of sensitive information within configuration files. By following these steps, Carbon Black can securely communicate with external services while adhering to network security policies requiring proxy filtering.

This document outlines how to configure Carbon Black (Cb) to use a web proxy for communication with Cb Alliance and Yum repositories. When security policies require traffic filtering through a web proxy, Cb can be configured to utilize it. The steps include editing configuration files and using utility scripts to secure the password handling process. 1. **Carbon Black Alliance Proxy Configuration**:

• Edit `/etc/cb/cb.conf` and uncomment lines to specify the proxy server for Cb Alliance access, replacing IP or DNS with the proxy's details.

• If the proxy requires authentication, set it up by adding the type (basic or ntlm), username (with optional domain), and password options. The password can be plaintext or encrypted; if using encryption, follow specific steps to generate an encrypted password.

• Restart `cb-enterprise` after configuration changes, adjusting commands for both clustered and non-clustered environments.

2. **Yum Repository Proxy Configuration**:

• Edit `/etc/yum.conf` to add proxy settings for Yum repositories using the same IP or DNS name as the Cb Alliance proxy server.

• Configure authentication if necessary by adding `proxy_username` and `proxy_password`.

3. **Generating an Encrypted Password**:

• Use a script `/usr/share/cb/cbpasswd --encrypt` to convert plaintext passwords into encrypted format, ensuring secure handling of sensitive information within the configuration files.

This setup ensures that Cb can securely communicate with external services while adhering to network security policies requiring proxy filtering. To summarize the given text, I will break it down and provide a concise description of its components. The provided text is a string of alphanumeric characters that appears to be a combination of letters and numbers: "3KW61ydeFMl47GF0l1aAoWUGEKGFgIai3ENdpPCo2DKCmUUMEbmvs/Pg". This sequence could represent various forms of encoded or encrypted data, potentially including characters from the English alphabet (both uppercase and lowercase), digits, as well as special characters such as "/", "p", "g", etc. Since it is a combination of letters, numbers, and possibly symbols, this string might be used in contexts where confidentiality, integrity, or authentication are required to ensure secure data transmission, storage, or processing. It could also represent an identifier, a code, or part of a protocol that involves complex encoding schemes for security purposes. However, without additional context or knowledge about the origin and intended use of this string, it is challenging to determine its specific function or meaning in detail.
