What is the OSI Model - 7 Layers of OSI Model Explained
International Organization for Standardization (ISO) developed the OSI model in 1984.
OSI model is an acronym for Open System Interconnect.
The OSI model is a model that allows us to categorize network communications and divide different activities of the network in seven conceptual layers.
This model tries to explain how the data of an application passes through the device and out in the physical network using the seven conceptual steps or layers.In simpler words, it explains how one application performs different steps to communicate its data to another application running on a different device.
The OSI model was created for creating a common industry standard, which could have helped inter-operability between different vendors.
However, this model did not gain a lot of popularity. So it is used as a reference or a teaching tool today. The OSI model does not directly match the networking systems we use in reality, but it is still useful because it describes the several processes used in electronic communication.

Dubbed CronRAT, the malware is currently targeting web stores and enables attackers to steal credit card data by deploying online payment skimmers on Linux servers.
