In which layer of the OSI model does the ICA protocol from Citrix operate?
In which layer of the OSI model does the ICA protocol from Citrix operate?
- Transport
- Application
- Presentation
- Physical
EXPLANATION
The Independent Computing Architecture (ICA) protocol operates at the presentation layer of the OSI model, that is, the 6th layer. ICA is a Windows presentation services protocol from Citrix that provides the foundation for turning any client device-thin or fat-into the ultimate thin client. In the case of the ICA protocol, the 6th layer or the presentation layer is responsible for making sure the data can be presented to the application layer, in other words, the presentation layer prepares/formats the data making it ready to be passed up to the application layer.

What international standard describes requirements for an information security management system (ISMS)?
What international standard describes requirements for an information security management system (ISMS)?
- GDPR
- ISO/IEC 27001
- ISO/IEC 27000
- ISO/IEC 27002
EXPLANATION
"Standards aren’t the same as regulations and following a standard doesn’t guarantee that you’re within the relevant laws."
GDPR is a data privacy law/regulation
created by the European Union (EU). It has an "extra-territorial
effect" to protect data belonging to EU citizens and residents. This not
only applies to EU-based organizations but also that in another region,
which target or collect data related to people from European Economic
Area (EEA).
ISO 27000 has an overview of ISMS and it contains terms and definitions.
ISO 27002 has guidelines and it's optional. However, there are useful tips related to the implementation of controls and requirements, which are provided in ISO 27001.
