Systems, devices, and methods are discussed for providing ZTNA control across multiple related, but independently provisioned networks.

Plural Internet of Things (IoT) gateways detect, secure against and remediate malicious code with an autonomous communication of tokens between the IoT gateways on a time schedule. Detection of an invalid token or a token communication outside of a scheduled time indicates that malicious code may have interfered with token generation or communication. Once malicious code is verified on an IoT gateway, the failed gateway is remediated to an operational state, such as with a re-imaging by another IoT gateway through an in band communication or a re-imaging by a server information handling system through an out of band communication.

A computer security architecture applies selected rules from among a set of rules defining one or more security policies to a given set of security context parameters to produce security verdicts, each representing whether a certain action requested by a subject entity is permissible. Each security policy is associated with a corresponding communication interface. A plurality of gateway engines are each associated with at least one of the subject entities and dedicated to interfacing with the security server. Each of the gateway engines carries out monitoring of requested actions by the associated subject entity and, for each requested action, identifies a security context. A security policy is determined for the requested action based on a corresponding security context, and a security verdict is obtained via a communication interface corresponding to the applicable security policy.

Systems and methods are described that mitigates and/or prevents distributed denial-of-service (DDOS) attacks. In one implementation, a gateway include one or more processors configured to obtain network data from one or more entities associated with the gateway, provide the network data to a server, and obtain a set of entity identifiers from the server. The set of entity identifiers may be generated based on at least the network data. The one or more processors may be further configured to filter communications based on the set of entity identifiers.

A Software Defined Wide Area Network (SD-WAN) edge node is disclosed. The SD-WAN edge node includes edge node SD-WAN ports coupled to untrusted underlay networks. The SD-WAN edge node transmits a first Border Gateway Protocol (BGP) update message advertising WAN (Wide Area Network) properties of the edge node SD-WAN ports to a local controller via an encrypted channel over the untrusted underlay network. The SD-WAN edge node receives a second BGP update message from the local controller, the second BGP update message advertising WAN properties of peer node SD-WAN ports of a peer node. The SD-WAN edge node establishes a security association with the peer node over the untrusted underlay networks based on the WAN properties of the edge node SD-WAN ports and the WAN properties of the peer node SD-WAN ports.

A system includes at least one server that is configured to provide a multi-client network service to a plurality of existing users. When the server receives requests to join the multi-client network service from new users, the server may issue timestamps to each new user, obtain load metric based on the requests or timestamps, and collect the load metric to obtain historical data characterizing a demand in the multi-client network service over time. Further, based on the historical data, the server can predict a future load demand in the multi-client network service and selectively enable to join the multi-client network service by at least one of the plurality of new users based on the future load demand.

A method and an apparatus are provided for deploying a security access control policy in the field of network security. The method, executed by a cloud management platform, includes: determining, according to an application creation instruction, an application template used for an application that needs to be created and a security profile corresponding to the application template; instructing a virtualization platform to create, according to the application template, a corresponding virtual machine for each application component in the application, and obtaining an IP address of each virtual machine created by the virtualization platform; generating a group of security access control policies corresponding to the application according to the IP address of each virtual machine and by using the security profile; and delivering the group of security access control policies to a corresponding firewall. Therefore, a security access control policy is automatically deployed.

A method for remote access includes obtaining, by a virtual private network (VPN) server, trust data of a user accessing a first network; determining, by the VPN server, a first trust level corresponding to the trust data according to a first correspondence, wherein the first correspondence comprises the trust data and the first trust level; determining, by the VPN server, a first access zone of the first network corresponding to the first trust level according to a second correspondence, wherein the second correspondence comprises the first trust level and the first access zone; and establishing, by the VPN server, a first VPN connection between a device used by the user and the first access zone.

In an illustrative embodiment, systems and methods for cyber vulnerability assessment include obtaining assessment data including information pertaining to domains of cyber security vulnerability of an enterprise and, for each security domain, a respective domain-level vulnerability score, identifying risk(s) relevant to the enterprise based on domain-level vulnerability score(s), identifying recommended products or services for mitigating each of the risks, and preparing a graphical user interface for selecting a portion of the recommended products or services. A user may select one or more products or services through the user interface for purchase and/or deployment planning. The domain-level vulnerability scores may be compared to peer vulnerabilities scores, target vulnerability scores, or prospective vulnerability scores based upon application of certain recommended products or services.

A method for operating a computing device for a control unit of a motor vehicle. The computing device including a processor core, and is configured to control an exchange of data between a connectivity zone and a security zone. The security zone includes at least one component which is necessary to drive the vehicle and has an elevated relevance with regard to safety. The connectivity zone including at least one component whose operation requires communication outside of the vehicle but is not required to drive the vehicle and does not have an elevated relevance with regard to safety. At least one first program executable by the computing device is assigned to a non-trustworthy zone, and at least one further program is assigned to a trustworthy zone. The component of the connectivity zone is assigned to the non-trustworthy zone, and the component of the security zone being assigned to the trustworthy zone.
