Data for the corporate network dark attack and defense war. Data caching, also known as data extrusion, refers to the transfer of data from a computer without authorization. For the corporate network, these types of attacks can be done manually, such as using a USB drive; in addition, this attack can also be automated, when the need to use the network to transfer data. In this article, we will highlight the web-based data caching techniques used during penetration testing, along with the corresponding security hardening measures. As tunneling technology, we assume that we do not have valid domain credentials. This means that I ...
Since the beginning of cloud computing, the basic process of deploying applications in the cloud has barely changed, by first Deploying application components and database elements, and then connecting them to users over the network.

All along, OpenStack has a clear Naas model in quantum (now Neutron), which is a good example of Naas evolution, and it can be seen that we are constantly moving forward. When setting up a cloud application connection service ...
