[[CNM MediaWiki]] (formerly known as [[CNM Wikiware]]; hereinafter, the ''Soft'') is a [[CNM stable app]] built with [[MediaWiki]]. It deploys [[MariaDB]] as its database management system. For a few years, the stable version of ''MediaWiki'' has not been updated due to new versions' conflict with our LDAP plugin. However, a decision has been made to migrate the integration to [[WSO2 IS]] and it is not clear whether LDAP will remain necessary. Also periodically there are problems with pictures, which the [[Warehouse for CNM Cloud]] project shall address.

[[Educaship MediaWiki]] (formerly known as [[CNM Wikiware]]; hereinafter, the ''Soft'') is the [[CNM stable app]] that is based on [[MediaWiki]], which is a [[commercial off-the-shelf]] ([[COTS]]) [[wiki engine]]. In addition, the ''Soft'' deploys [[Educaship MariaDB]] as its [[database management system]] and [[Educaship LDAP]] for its [[authentication]] and [[authorization]].

Guys, we are looking for one or more MediaWiki experts to resolve one or more of the challenges that are best described below.
 +
* Screening question: Have you found the description of the challenges? May you resolve one or more of them? Which one or ones?
 +
* We are open to teams. LDAP-MediaWiki and MediaWiki itself may require experts with different skill sets. We are interested in WSO2 IS - MediaWiki as well since we plan to add WSO2 IS. So, WSO2 IS-MediaWiki expert may be another freelancer.

===File repository===
 +
: [[Software repository]]:
 +
:# Currently, the ''Soft'' itself is used as the repository; no federated repository is available. Because [[Opplet]] includes a few [[end-user application]]s, there is an idea to create one under the [[Warehouse for CNM Cloud]] project. Similarly, [[Wikipedia]] utilizes [[Wikimedia Commons]] as its repository.
 +
:# In addition, a few problems with pictures occurred in the past. As of early 2023, no problems are observed, but the quantity of stored files are about to increase significantly.
 +
:# [[SVG]] file support is another issue of the ''Soft'' development. The overwhelming majority of corporate files are in the [[SVG]] format, but, because the ''Soft'' doesn't support SVG, they need to be converted in the [[PNG]] one.
  
−
===System-user roles===
+
: So, the team looks for moving the ''Soft's'' files into a new repository. Under the most desired solution, (a) its files shall be available to various applications within [[Opplet]] and (b) SVG-files shall be stored there and displayed properly by the ''Soft's'' instances. If the most desired solution is not feasible, under an acceptable solution various instances of the ''Soft'' shall display the repository's files. The team will provide the hired expert with full access to two virtual machines; on the one ''Soft's'' instance is installed and on the second one a new repository should be installed.
−
:[[Opplet]] handles [[identity and access management]] for the ''App'' (including "create account" and "change other users' rights" functions). Thus, the [[system-user role]]s of the ''App's'' users are those [[Opplet role]]s that are specifically based on rights of groups granted by [[MediaWiki]]. The software-defined rights can be found at [https://www.mediawiki.org/wiki/Manual:User_rights#List_of_groups MediaWiki's list of groups].

: [[Opplet]], which part the ''Soft'' is, has a dedicated email server; the team wonders whether we can plug a ''Soft'' email client, which is currently unused, into that server. So, the most desired solution would be integration to our Postfix/Dovecot server; if the most desired solution is not available, internal email functioning would be accepted. The team will provide the hired expert with full access to the virtual machine on which ''Soft's'' instance is installed.

#*Read and/or view contents of any wikipage at clearly understood [[URL]]s such as starting with https://wiki.friendsofcnm.org/
 
−
#*See the logo at the right upper corner and the name of the resource such as [[CNM Wiki]];
 
−
#*Feel safe while seeing that the ''App's'' resource is verified by the [[SSL certificate]];
 
−
#As a Russian-speaking [[NetAnyone]], I need to be able to locate wikipages in Russian, possibly, at [[URL]]s starting with https://wiki.friendsofcnm.org/ru
 
−
#As a [[NetConsumer]], I need to be able to add selected wikipages to my watchlist and receive notifications when the watched wikipages are updated to my email.
 
−
#As a [[CertAssociate]], I need to be able to:
 
−
#*Have predefined rights of a user (with a registered account) established at [[MediaWiki]];
 
−
#*Upload files, including [[SVG]] graphics, with sizes up to 2Mb; the combined size of all downloaded files shouldn't exceed 200Mb.
 
−
#As a [[CertFellow]], I need to:
 
−
#*Have predefined rights of a sysop established at [[MediaWiki]];
 
−
#*Be able to upload files up to 20Mb.

#As a [[OppletBureaucrat]], I need to:
 
−
#*Have predefined rights of a bureaucrat established at [[MediaWiki]];
 
−
#As a [[CloudAdmin]], I need to:
 
−
#*Make sure that [[CNM Wiki]] at least gets basic [[cyber-security]] features, especially [https://www.mediawiki.org/wiki/Manual:Security Manual:Security], implemented; new threats are monitored and, based on them, the security policy should be defined and, further, re-defined;
 
−
#*Be able to restore [[CNM Wiki]] if the working software collapses. No more than one hour of work is allowed to be lost.

===SOP===
−
The ''App'' is a [[MediaWiki]] instance that is run on [[CNM Farms]].
+
: Currently, [[CNM Farms]] policies are utilized for archive, backup, monitoring, security, snapshot, and restoration policies. However, there could be some ''Soft's'' useful plugins or policies that the team is unaware of. Specifically to its security, the team hasn't done pretty much anything. So, the team looks for (a) the updated ''Soft's'' [[standing operating procedure]] ([[standing operating procedure|SOP]]) and (b) a the ''Soft'' instance that would be built using the new ''SOP''. The team will provide the hired expert with full access to a virtual machine on which ''Soft's'' instance can be installed.

:#Provides an audit trail that can provide identification of who has entered any new information.
 
  
−
:[[MediaWiki]] also has a provision for the future usage of multiple languages. When the time for adding a new language comes, the existing system shall enable this addition without need for additional components to the original system. It will also enable the user to nominate their preferred language when entering their personal information.

:Currently, the ''App'' uses an outdated, [[Special:Version|1.26.4 version]] of [[MediaWiki]], because the extension used to connect to its [[OpenLDAP]] does not support newer versions.

:[[PHP security]] is needed for pretty much any PHP environment; it is not necessarily specific to the ''App''.
 
−
LocalSettings.php usually contains sensitive data such as database logins. This data should never be revealed to the public! Due to a security breach somewhere on the server, it might happen that other users are able to view the contents of files. In order to improve security of your data, you should set UNIX permissions for this file accordingly: The webserver user must have access to this file. If this is the same account, who is the owner of the file, then you can set permissions to 600. Sometimes, the webserver user is not the file owner, but they are in the owner's UNIX user group. In this case, permissions of 640 should be fine. For improved security you should narrow permissions down as far as possible.

−
Additionally, you can create a MySQL user, who is restricted to only the database used by the wiki and provide this user's credentials in LocalSettings.php. Also you can configure your database server to only accept connections from localhost - this should prevent access from outside in case of leaked credentials.

Latest revision as of 06:23, 15 April 2024

Educaship MediaWiki (formerly known as CNM Wikiware; hereinafter, the Soft) is the CNM stable app that is based on MediaWiki, which is a commercial off-the-shelf (COTS) wiki engine. In addition, the Soft deploys Educaship MariaDB as its database management system and Educaship LDAP for its authentication and authorization.

The Soft is configured to power CNM Wiki, WikiHandsOn, or WikiNext, which are both CNMCyber services and parts of Opplet.


Challenges

Guys, we are looking for one or more MediaWiki experts to resolve one or more of the challenges that are best described below.

  • Screening question: Have you found the description of the challenges? May you resolve one or more of them? Which one or ones?
  • We are open to teams. LDAP-MediaWiki and MediaWiki itself may require experts with different skill sets. We are interested in WSO2 IS - MediaWiki as well since we plan to add WSO2 IS. So, WSO2 IS-MediaWiki expert may be another freelancer.

LDAP integration (urgent task)

Main wikipage: CNM MediaWiki IAM

File repository

Software repository:
  1. Currently, the Soft itself is used as the repository; no federated repository is available. Because Opplet includes a few end-user applications, there is an idea to create one under the Warehouse for CNM Cloud project. Similarly, Wikipedia utilizes Wikimedia Commons as its repository.
  2. In addition, a few problems with pictures occurred in the past. As of early 2023, no problems are observed, but the quantity of stored files are about to increase significantly.
  3. SVG file support is another issue of the Soft development. The overwhelming majority of corporate files are in the SVG format, but, because the Soft doesn't support SVG, they need to be converted in the PNG one.
So, the team looks for moving the Soft's files into a new repository. Under the most desired solution, (a) its files shall be available to various applications within Opplet and (b) SVG-files shall be stored there and displayed properly by the Soft's instances. If the most desired solution is not feasible, under an acceptable solution various instances of the Soft shall display the repository's files. The team will provide the hired expert with full access to two virtual machines; on the one Soft's instance is installed and on the second one a new repository should be installed.

Mail

Opplet, which part the Soft is, has a dedicated email server; the team wonders whether we can plug a Soft email client, which is currently unused, into that server. So, the most desired solution would be integration to our Postfix/Dovecot server; if the most desired solution is not available, internal email functioning would be accepted. The team will provide the hired expert with full access to the virtual machine on which Soft's instance is installed.

SOP

Currently, CNM Farms policies are utilized for archive, backup, monitoring, security, snapshot, and restoration policies. However, there could be some Soft's useful plugins or policies that the team is unaware of. Specifically to its security, the team hasn't done pretty much anything. So, the team looks for (a) the updated Soft's standing operating procedure (SOP) and (b) a the Soft instance that would be built using the new SOP. The team will provide the hired expert with full access to a virtual machine on which Soft's instance can be installed.

Guided tour

We use the CNMCyber Guided Tours format and need someone to organize an event that would present the Soft. The event should feature:
  1. A speaker and/or presenter who would demonstrate a separate, so-called experiential, instance of the Soft, while following its description. The participants shall follow the presentation, try the Soft instance on their own, ask questions, and get the speaker/presenter answers.
  2. Recording that would be published online by the team.

Markup specification

Talk-page rename

Business functionality

Besides supporting CNM Wiki, the App serves as a practice tool in the learning that is delivered by Bracka School and related to knowledge management software.

System-user roles

Opplet handles identity and access management (IAM) for the Soft's instances (including "create account" and "change other users' rights" functions). Thus, the system-user roles of the Soft's users are those Opplet roles that are specifically based on rights of groups granted by MediaWiki. The software-defined rights can be found at MediaWiki's list of groups.

Platform

Main wikipage: CNM Farms
CNM Farms shall provide every instance of the Soft with all resources that the Soft needs in order to run smoothly, including:
Particularly, the platform shall not store any confidential information, so such information cannot be accessed by anyone.

Security

Vulnerability alerts

Extensions

  • Extensions
  • Sendmail is required in order for the system to be able to send e-mails.
  • Shell access is required to run maintenance scripts; upgrading MediaWiki may be more difficult without it.

File permissions

Main wikipage: File permission

Maintenance scripts

Upload security

Main wikipage: Upload_security 

   Upload permissions
   Per default, all registered users can upload files. To restrict this, you have to change $wgGroupPermissions:
   To prevent normal users from uploading files:
   $wgGroupPermissions['user']['upload'] = false;
   To create a special group called "uploadaccess", and allow members of that group to upload files:
   $wgGroupPermissions['uploadaccess']['upload'] = true;

Development

Development of the Soft occurs under the MediaWiki for CNM Cloud project.
