What are common files on a web server that can be misconfigured and provide useful information for a hacker such as verbose error messages?

Option 1 : idq.dll
Option 2 : administration.config
Option 3 : httpd.conf
Option 4 : php.ini

If you begin the software Microsoft Windows on your PC, the commands contained in idq.dll are going to be executed on your PC. For this purpose, the file is loaded into the most memory (RAM) and runs there as a Microsoft Indexing Service ISAPI Extension process (also called a task).

Is idq.dll harmful?

This process is taken into account safe. it’s unlikely to pose any harm to your system.

2. administration.config

This configuration file stores the settings for IIS management. These settings include the list of management modules that are installed for the IIS Manager tool, also as configuration settings for management modules.

3. httpd.conf

Apache HTTP Server is configured by placing directives in plain text configuration files. the most configuration file is typically called httpd.conf. the situation of this file is about at compile-time, but could also be overridden with the -f instruction flag. additionally , other configuration files could also be added using the Include directive, and wildcards are often wont to include many configuration files. Any directive could also be placed in any of those configuration files. Changes to the most configuration files are only recognized by httpd when it’s started or restarted.
The server also reads a file containing mime document types; the filename is about by the TypesConfig directive, and is mime.types by default.
httpd configuration files contain one directive per line. The backslash “\” could also be used because the last character on a line to point that the directive continues onto subsequent line. There must be no other characters or white space between the backslash and therefore the end of the road .
Arguments to directives are separated by whitespace. If an argument contains spaces, you want to enclose that argument in quotes.
Directives within the configuration files are case-insensitive, but arguments to directives are often case sensitive. Lines that begin with the hash character “#” are considered comments, and are ignored. Comments might not be included on an equivalent line as a configuration directive. White space occurring before a directive is ignored, so you’ll indent directives for clarity. Blank lines also are ignored.
The values of variables defined with the Define of or shell environment variables are often utilized in configuration file lines using the syntax ${VAR}. If “VAR” is that the name of a legitimate variable, the worth of that variable is substituted into that spot within the configuration file line, and processing continues as if that text were found directly within the configuration file. Variables defined with Define take precedence over shell environment variables. If the “VAR” variable isn’t found, the characters ${VAR} are left unchanged, and a warning is logged. Variable names might not contain colon “:” characters, to avoid clashes with RewriteMap’s syntax.
Only shell environment variables defined before the server is started are often utilized in expansions. Environment variables defined within the configuration file itself, for instance with SetEnv, become too late to be used for expansions within the configuration file.
The maximum length of a line in normal configuration files, after variable substitution and joining any continued lines, is approximately 16 MiB. In .htaccess files, the utmost length is 8190 characters.
You can check your configuration files for syntax errors without starting the server by using apachectl configtest or the -t instruction option.
You can use mod_info’s -DDUMP_CONFIG to dump the configuration with all included files and environment variables resolved and every one comments and non-matching and sections removed. However, the output doesn’t reflect the merging or overriding which will happen for repeated directives.

4. php.ini

The php.ini file may be a special file for PHP. it’s where you declare changes to your PHP settings. The server is already configured with standard settings for PHP, which your site will use by default. Unless you would like to vary one or more settings, there’s no got to create or modify a php.ini file. If you’d wish to make any changes to settings, please do so through the MultiPHP INI Editor.
