Selecting a software for an information security management system (ISMS) is a complex undertaking. An important building block is a list of criteria that are important for one's own organization. Such a criteria catalog makes it easier to compare the various products with each other. The basis for such a requirements catalog can be found here as an open Excel file, which you can use free of charge for your internal purposes.

Introduction

The catalog covers both the business and the technical aspects as well as the software selection itself. However, you should not adopt it unchanged, but first adapt it to your needs. This means including additional requirements that are important to you. But also removing unnecessary requirements.

Preview

Since downloading an Excel file from the Internet always requires some courage, you will first see a preview of the contents here on images or as a PDF file. You can remove the logo in Excel of course 😊

C.3 Accessibility

This part is only relevant if the system is intended for use by disabled people or if rules of the organisation require that accessibility must be provided.
A blanket requirement to comply with the relevant guidelines like WCAG would usually be inappropriate, as these primarily relate to web presences on the Internet. For (web) applications, only some of the requirements are relevant and meaningful.

C.7 Performance

95: Please confirm: The system is able to handle the data volumes specified in the concept
96: Please confirm: The system has the following response times with the data volumes and parallel user numbers mentioned in the concept: - Lists and edit masks open within 2 seconds in 90% of the cases. - Reports open within 10 seconds in 90% of the cases
Adjust the numbers according to your needs, but remain realistic. This includes that there are always masks that need a little longer. But these should not be the masks that are permanently used - so limit it sensibly.

C.8 IT Security

97: Describe the measures and processes you use to identify and clean up security vulnerabilities in the application.

C.9 Data privacy

98: Describe how the system supports the implementation of the GDPR.
How are requests from data subjects implemented? Is there a concept for deleting data when the deletion periods expire?

D.1 System architecture

119: Describe the basic system architecture of your application. Address components such as client, server, database, interfaces, and so on
120: Are there solutions for high availability?

D.2 On-Premise Installation

In the case of an installation in the company's own data center (on-premises), there are usually specifications from IT or the IT service provider as to which infrastructure components can be used. This includes operating systems, databases and application servers. Example: The data center provides MS SQL Server as database, but no Oracle. The vendor's software must support these components, otherwise it cannot be installed and operated on-premises. Therefore, adjust the following requirements according to the specifications and use them to ask the vendor whether it supports the respective component.
Omit this section if you are looking exclusively for a cloud solution.
D.2.1 Application server
121: If the application requires a server: Describe the system requirements for the server with supported operating systems, required runtime environments, and so on.
122: If the application requires a proprietary base system such as MS Sharepoint: Describe the prerequisites.
If the application is based on a proprietary system and one of these systems is already in use at your company, then it can significantly reduce the technical effort. However, if this system is not used by you, then noticeable additional costs and additional efforts may arise.
123: Provide a sizing recommendation for the data volumes and user counts (CPUs, main memory, disk space, etc.) specified in the concept.
Refer to the quantity structure of users and data you are calculating with in the application.
124: How can the server be scaled as needed?
Vertically: increase the performance of the server. Or horizontally: deploy more servers
125: Are there container images?
For a deployment with Docker / Kubernetes, for example.
D.2.2 Database
126: Is a database required?
Some applications bring their own database, other applications require the presence of a database.
127: Which databases (including versions) are supported by the application? Is a license-free database also supported?
Add the database(s) that are supported in your organization, e.g. Oracle 19c, MS SQL Server 2019, MariaDB 10.
128: Provide a sizing recommendation for the data volumes and user counts identified in the concept.

D.3 Network

129: What are the requirements for network speed or bandwidth?
This question is particularly relevant for locations with poor network connectivity.

D.4 Client

Ideally, the application is completely operable via the browser for end users, so that no installation is required on the workstation computer. Alternatively, the software can also be installed locally, especially for a manageable number of users.
130: Does software need to be installed on the workstation for end users to use the system?
131: Do I need to install software on the workstation to administer the system?
D.4.1 Locally installed client
132: Which operating systems are supported for a client installation?
133: Is a runtime environment required on the workstation to run the client?
134: What requirements in terms of CPU performance, main memory and disk space must the workstation computer meet?
D.4.2 Browser
135: Which browsers are supported? (with versions)
The question is aimed at whether the browsers allowed or required in your organization are supported.
136: Does the system require outdated runtime environments in the browser, such as client-side Java, Flash, or Silverlight?
There should no longer be any new applications introduced that require the mentioned runtime environments.

D.5 Mobile use

137: Is the user interface responsive?
138: What types of mobile devices are supported (smartphone, tablet)?
139: Is the application usable on the browser of mobile devices?
140: Is there a native app for the application? Describe the range of functions compared to the desktop or browser version.
141: Which mobile operating systems are supported?
Should be narrowed down to mobile operating systems used in your organization.
142: Can the app be administered with mobile device management?
If necessary, ask specifically for the MDM systems available in your organization.

D.6 User administration

Often there are two types of users:
- Users managed locally in the application: These are used, for example, when there are only a few users and local maintenance is easier than creating and maintaining an LDAP interface. Or when external users are to be integrated that one does not want to maintain in one's own LDAP.
- Users managed in a directory service: As a rule, users are maintained centrally in systems such as Active Directory. The information is then synchronized with the application via an interface and is available there. This simplifies the administration of users, but requires a corresponding LDAP interface.
Depending on the complexity of the organization and the requirements, mixed operation may also make sense or it must be possible to read in user information from several directory systems.
143: Is there a local user management in the system?
144: Is there an LDAP interface to synchronize users from a directory? Is a connection to ... supported?
Add the directory services that are relevant to your organization, e.g. Active Directory

D.7 Authentication

145: Is single sign-on (SSO) supported? Describe the possibilities.

D.8 Interfaces

146: Explain your methodology for interfacing with third party systems.
147: To which third-party systems are there standard connectors?
