A network apparatus receives a connection request from a client computing device toward a target computing device. Next a target identifier that identifies the target computing device is extracted from the connection request. The connection request is sent to the target computing device and a reputation request with the target identifier is sent to a web resource analyser engine. In response to detecting that a response from the target computing device is received before a response from the web resource analyser engine, the response to the connection request from the target computing device is held by performing a rewrite in a target section of a user-space utility program rule and by using operating system kernel module in user-space memory area of the network apparatus. In response to a receipt of the response from the web resource analyser engine, the response to the connection request is released.

Described are examples for providing a system for managing configuration and policies for a virtualized wide area network (vWAN) support on a wide area network (WAN). The vWAN includes a plurality of virtual network entities associated with geographic locations including the physical computing resources of the WAN and virtual connections between the virtual network entities. The system includes a network safety component for managing configurations and policies of the vWAN on the WAN. The network safety component receives a change to a policy or configuration of the vWAN from an operator of a network connected to the vWAN. The network safety component evaluates a set of safety rules for the operator based on the change and a network state of a physical WAN underlying the vWAN. The network safety component generates an error message in response to at least one of the set of safety rules failing the evaluation.

Described embodiments provide systems and methods for selecting one or more firewall rules to apply to a server based at least on identifying a service of the server. A device intermediary to a plurality of clients and a serve may identify a pattern of a firewall to apply to a response from the server to a request from a client of the plurality of clients. The pattern may be to identify a service configured on the server. The device may determine that the response from the server matches the pattern. The device may identify, responsive to the response matching the pattern, that the service is configured on the server. The device may select, based at least on the service, one or more rules for the firewall to apply to responses from the server.

Management of IoT devices through a private cloud. An IoT device is coupled to a gateway. A request from the IoT device to connect to a private cloud, wherein the private cloud is used to manage IoT devices, is received at a private cloud control center agent. An identification of the IoT device is determined. The IoT device is onboarded, using the identification, for management through the private cloud. A device profile of the IoT device is generated. The flow of data to and from the IoT device is regulated through application of IoT rules according to the device profile of the IoT device.

Users of an endpoint remediation system can be assigned to different roles, from which they can request exceptions, approve exceptions, and/or enable remediation on endpoint devices. The compliance scanning and enforcing process can be automated, while allowing entities to request and/or approve certain exceptions. Therefore, security compliance for customers can be actively managed to provide visibility to the endpoint device compliance state at any time.

An Internet of Things (IoT) protection service at the network level is described. A secure session is established between an edge server and an IoT client that is requesting to send data to an IoT device. The edge server receives the request from the IoT client over the secure session instead of the IoT device directly because a Domain Name System (DNS) request for a unique fully qualified domain name assigned to the IoT device returns an IP address of the edge server instead of an IP address of the IoT device. The edge server analyzes the request to determine whether to transmit the request to the IoT device, including applying web application firewall rule(s) against the request. If the request does not trigger any rule, then the edge server transmits the request to the IoT device. If the request triggers any rule, then the edge server blocks the request.

Modern day user applications leverages new communication technologies such as WebRTC, WebEx, and Jabber allow devices to connect and exchange media content including audio streams, video streams, and data stream/channels. The present disclosure describes mechanisms for a Port Control Protocol (PCP) server to provide feedback to PCP clients to enforce certain policies on the transport of such media content for a network. A policy may include a traffic handling policy for enforcing differentiated quality of service characteristics for different types of media streams. Another policy may include a security policy ensuring a data files being transmitted over a data channel from one endpoint travels to a security application via a relay element before the packets reaches another endpoint. The mechanisms are transparent to the endpoints, and advantageously preserve the user experience for these user applications.

Assistance method for managing a cyber attack, and device and system thereof. The assistance method is implemented by a device managing resources of a computing domain, these resources being protected by a plurality of cyber attack protection services. The method includes: determining an incapability of a first protection service from among the plurality of protection services to handle a cyber attack targeting at least one resource of the computing domain; developing a mitigation plan for mitigating the attack based on a mitigation plan obtained from a second protection service from among the plurality of protection services or using assistance provided by at least the second protection service; and transmitting the developed mitigation plan to the first protection service to handle the attack.

A gateway device (10) stores therein a first filtering rule and a second filtering rule for filtering packets which are transmitted from a terminal (20) in a network (2) as a transmission source to a terminal (20) in a network (3) as a destination. The gateway device (10) acquires, on the basis of a packet transmitted from the terminal (20) in the network (3), identification information for identifying the terminal (20). The gateway device (10) notifies a management device (30) of the acquired identification information. The management device (30) generates a management screen on the basis of the notified information, and transmits the management screen to a display device (40). The management device (30) transmits an instruction based on input to the display device (40) to the gateway device (10). The gateway device (10) sets the first filtering rule on the basis of the instruction from the management device (30).

Technologies for updating an access control list (ACL) table while minimizing disruption includes a network device. The network device receives a request to store a rule in the ACL. The rule is associated with a precedence group. A precedence group is indicative of a placement priority of a given rule in the ACL. The network device determines, as a function of the precedence group, a placement for the requested rule in the ACL. The network device stores the rule according to the determined placement in the ACL.
