Abstract: The present disclosure discloses configuring a device to determine an assigned public key and an assigned private key; configuring the device to determine a content access public key and a content access private key; configuring the device to determine, for a folder, a folder access public key and a folder access private key; configuring the device to encrypt the content access private key by utilizing the assigned public key; configuring the device to encrypt the content access private key by utilizing the folder access public key; configuring the device to transmit the encrypted content, the first encrypted content access private key, and the second encrypted content access private key to a server for storage; and configuring the device to access, from the server, the encrypted content by decrypting the first encrypted content access private key or by decrypting the second encrypted content access private key. Various other aspects are contemplated.

Abstract: In an embodiment, a set of labeled training data that includes indicators of webpages is received. Each indicated webpage is labeled with one or more categories that were determined for the webpage by a human reviewer. Features, such as text and scripts, are extracted from each indicated webpage, and are used along with the labels to train a classifier to predict one or more categories for a webpage based on the features of the webpage. The trained classifier may be used to associate one or more categories with each domain of a plurality of domains given the categories predicted for some or all of the webpages associated with the domain. A list of domains and associated categories may be used for a variety of purposes including search engine optimization and content filtering.

Abstract: A method including receiving, by a security device from a user device that is in a private network, a transmission packet for communication to a destination device over an open network; determining, by the security device based on receiving the transmission packet, whether the user device is permitted to transmit the transmission packet to the destination device over the open network; determining, by the security device based on determining that the user device is permitted to transmit the transmission packet to the destination device, whether the user device is permitted to utilize a protocol utilized by the user device to transmit the transmission packet; and determining, by the security device based on determining that the user device is permitted to utilize the protocol, whether the user device is permitted to utilize a transmission web application utilized by the user device to transmit the transmission packet is disclosed.
