If the packet information does not match information in a first data flow table, a first compliance detection is performed on the data packet. A state machine of the TCP connection is obtained if the first compliance detection is successful. The method also includes recording the packet information in the first data flow table, recording a connection status of the TCP connection in a first connection tracking table, and sending the data packet to a receiving end of the TCP connection. If the packet information matches the information in the first data flow table, a second compliance detection is performed on the data packet and, if the second compliance detection fails, the connection status of the TCP connection is adjusted and the data packet is discarded. |

Managing mobile device user subscription and service preferences to predictively pre-fetch content
A content delivery network (CDN) is enhanced to enable mobile network operators (MNOs) to provide their mobile device users with a content prediction and pre-fetching service. Preferably, the CDN enables the service by providing infrastructure support comprising a client application, and a distributed predictive pre-fetching function. The client application executes in the user's mobile device and enables the device user to subscribe to content (e.g., video) from different websites, and to input viewing preferences for such content (e.g.: “Sports: MLB: Boston Red Sox”). This user subscription and preference information is sent to the predictive pre-fetching support function that is preferably implemented within or across CDN server clusters. A preferred implementation uses a centralized back-end infrastructure, together with front-end servers positioned in association with the edge server regions located nearby the mobile core network. The predictive pre-fetch service operates on the user's behalf in accordance with the user preference information. |

Determining accuracy of characteristics asserted to a social networking system by a user
A social networking system maintains characteristics with its users, with various characteristics, such as age, specified by the users (i.e., “asserted characteristics”). The social networking system selects content for a user based at least in part on the characteristics associated with the user. To account for potential inaccuracies in an asserted age of a user, the social networking system clusters users based on ages of other users connected to users. The online system receives verified ages for users in a cluster from a trusted third party system that maintains more accurate characteristics for users than the social networking system. By comparing the asserted ages for users in the cluster to the verified ages for users in the cluster, the social networking system determines an accuracy of the asserted ages for users in the cluster. The accuracy may be used when selecting content for the users. |

Protecting from directory enumeration using honeypot pages within a network directory
There are provided systems and methods for protecting from directory enumeration using honeypot pages within a network directory. A service provider, such as an electronic transaction processor for digital transactions, may have an internal network that is utilized by employees, developers, and other end users within the organization of the service provider.

The service provider may therefore detect a scan of an internal directory having files paths to files and pages and may deploy honeypot pages that change an error status. Further, the service provider may add a process or operation to log additional data on these honeypot pages and/or change a byte size of the corresponding pages to confuse the enumeration attempt and obtain true source information. |

Securing access to network devices utilizing two factor authentication and dynamically generated temporary firewall rules
A network security system provides portals which enable automatic creation of a dynamic one-time port forwarding rule for an authorized user's current IP address following two factor authentication of the authorized user. Such a dynamic one-time port forwarding rule is utilized to set up a connection, at which point the dynamic one-time port forwarding rule is removed, preventing any attacker from subsequently taking advantage of it. Such a methodology is advantageous as compared to conventional port forwarding in that it is much more secure. Such a methodology is advantageous as compared to traditional port forwarding with access control both in that a user does not always have to utilize the same device with a static IP address, and in that the port forwarding rule representing or exposing a potential vulnerability is deleted after a connection is established. |

Communicating single-address reply messages to all addresses of recipients of a group message
Implementations set forth herein relate to subjecting a message to a group rule that causes any message, in a message thread that includes the message, to include certain addresses, regardless of the addresses that are incorporated, by a user, into an address field of a reply message.

The present disclosure provides an analytical framework to investigate judicious topology reweighting of radio networks of clocks, when distributed time transfer and synchronization are based on physical layers and subject to the presence of false timing signals. Protagonist clocks exchange timing information pairwise, which is modeled as clocks tending to follow the majority of their neighbors. Antagonist clocks inject false timing signals, thereby, influencing the timing synchronization of (some of) the other protagonist clocks they meet. A class of pursuit-evasion graphical games subject to complete state observations and exploitation of phase noise disturbances, is proposed in designing clock steering protocols for resilient time metrologies that will be immune to erroneous timing signals injected into remote time dissemination networks. |
