A computing includes a hardware platform having a processor and a memory; and instructions encoded within the memory to instruct the processor to: on behalf of a human user, scan a social media platform for which the user has an account, and compute a proactive privacy risk score, wherein the proactive privacy risk score is a quantitative value based at least in part on an inherent risk of the social media platform according to data types that may be collected and exposed by the social media platform, and at least in part on privacy settings for the social media platform in relation to the data types; and recommend or initiate an action to improve the proactive privacy risk score.

Quantified social media privacy

There is disclosed in one example an enrollment over secure transport (EST)-capable gateway device, including: a hardware platform including a processor and a memory; a first network interface to communicatively couple to an external network, including an external DNS server; a second network interface to communicatively couple to a home network; a caching DNS server including a local DNS cache, and logic to provide DNS services to the home network; and an EST proxy to authenticate to a local endpoint on the home network, provision a DNS server certificate on the local endpoint, provision an authentication domain name (ADN) on the local endpoint, and provide encrypted domain name system (DNS) services to the local endpoint.

Methods, apparatus, systems, and articles of manufacture are disclosed to improve the inspection of network data flows. An example apparatus includes memory, and processor circuitry to execute machine readable instructions to at least identify network domains accessible by at least one client device in a geographic location of interest, associate the identified network domains with Autonomous System Numbers (ASNs), create a list of respective ones of the ASNs that include a non-malicious status corresponding to Internet protocol (IP) addresses associated with respective ones of the identified network domains, and in response to receiving a reputation request corresponding to a destination IP address, cause inspection of a data flow to be skipped when the destination IP address is associated with the list of non-malicious ASNs.

Methods, systems, articles of manufacture and apparatus to reduce computation corresponding to inspection of non-malicious data flows

There is disclosed in an example a gateway device, including a hardware computing platform, and a secure domain name system (DNS) engine having circuitry and stored instructions to-program the circuitry, the secure DNS engine to communicatively couple to an endpoint via a local network, begin a secure DNS transaction with the endpoint, determine whether the endpoint supports delegated credentials, and after determining that the endpoint supports delegated credentials, establish a secure DNS session with the endpoint using a delegated credential.

Secure DNS using delegated credentials and keyless SSL

Methods, apparatus, systems and articles of manufacture are disclosed to verify application permission safety. An example apparatus to identify unsafe permissions associated with a candidate app disclosed herein includes an app classifier interface to retrieve a cluster of apps associated with the candidate app, the candidate app including a requested permission set (RPS), a white knight (WK) identifier to identify a set of WK apps within the cluster, the set of WK apps associated with a designation of trust, a safe permission set (SPS) evaluator to generate an SPS list associated with the set of WK apps within the cluster, and an RPS identifier to determine whether permissions of the RPS are listed in the SPS list, the SPS evaluator further to designate first respective ones of the permissions of the RPS as safe when the first respective ones of the permissions are listed in the SPS list, and designate second respective ones of the permissions of the RPS as unsafe when the second respective ones of the permissions are absent from the SPS list.

Methods, systems, articles of manufacture and apparatus to verify application permission safety

There is disclosed in one example a network gateway device, including: a hardware platform including a processor and a memory; a network interface, including network interface hardware; and instructions encoded within the memory to instruct the processor to: receive from an endpoint device, via the network interface, a signed security posture data structure, the signed security posture data structure including information about a security posture of the endpoint device; cryptographically verify the signed security posture data structure; and according to the signed security posture data structure, assign a network security policy to the endpoint device.

Secure attestation of endpoint capability

There is disclosed in one example a computing apparatus, including: a hardware platform including a processor, a memory, and a network interface; and instructions encoded within the memory to instruct the processor to: receive an incoming packet via the network interface; extract from the incoming packet a source port and a source internet protocol (IP) address; correlate the source port and source IP to a device identifier (ID); receive a network policy for the device ID; and apply the network policy to the incoming packet.

Agentless security services

Methods, apparatus, systems and articles of manufacture for communicating encrypted data via a virtual private network are disclosed. An example computer system disclosed herein includes a memory including instructions that, when executed, cause one or more processors to establish a first tunnel and a second tunnel between a VPN client and a VPN server. The instructions further cause the one or more processors to access a request message to be sent via the VPN and determine, in response to a payload being formatted using a first protocol, whether a packet associated with the request message includes an encrypted server name indication (SNI). The instructions further cause the one or more processors to, in response to the packet including the encrypted SNI, encrypt the header of the request message to form an encrypted header, create an encrypted message including the encrypted header and the payload of the request message, and transmit the encrypted message through the first tunnel.

Methods, apparatus, and systems for an encryption mode via a virtual private network

Example methods, apparatus, systems and articles of manufacture to implement cooperative mitigation of distributed denial of service attacks originating in local networks are disclosed. An example network element disclosed herein is to detect a first distributed denial of service attack associated with first network traffic received by an Internet service provider network, the first network traffic originating from a first device connected to a local network. The disclosed example network element is also to implement a threat signaling client to transmit first information describing the first distributed denial of service attack to a threat signaling server implemented by a local network router of the local network, and receive second information from the threat signaling server of the local network, the second information to provide a notification when the first network traffic associated with the first distributed denial of service attack has been mitigated.
