A method for authenticated asset assessment is provided. The method involves executing a scan assistant on an asset to allow a remote scan engine to execute one or more scan operations on the asset for determining a state of the asset. The scan assistant may verify the identity of the scan engine by checking that a certificate received from the scan engine is signed with a private key associated with the scan engine. In some embodiments, the authentication may be performed as part of a TLS handshake process that establishes a TLS connection between the scan engine and the scan assistant. Once the scan engine is authenticated, the scan engine may communicate with the scan assistant according to a communication protocol to collect data about the asset. Advantageously, the disclosed technique reduces security risks associated with authenticated scans and improves the performance of authenticated scans.

Signed remote execution for assessment of network system assets

As an example, an asset receives a request from a scanner performing a reconnaissance of a network that includes the asset. The asset sends a response acknowledging receiving the request, indicating that the asset is alive. The asset receives port scan requests associated with ports of the asset. The asset creates fake fingerprints that include incorrect information about ports of the asset. The asset sends the fake fingerprints to the scanner in response to the port scan requests. The asset determines that a scan engine is requesting access to the asset via a particular port of the asset. The asset grants the scan engine access to the asset via the particular port to enable the scan engine to gather asset data associated with the asset for analysis.

Policy exceptions for assessment of network system assets

A method for authenticated asset assessment is provided. The method includes authenticating, by a scan assistant, a scan engine with the scan assistant for executing one or more scan operations on the asset to determine a state of the asset. The asset includes at least one computing resource. The method also includes receiving, by the scan assistant, a plurality of scan requests associated with the one or more scan operations from the scan engine. The method further includes responding, by the scan assistant, to at least one scan request of the plurality of scan requests by transmitting one or more scan responses to the scan engine after receiving the plurality of scan requests. The scan assistant and the scan engine implement an asynchronous communication protocol that permits the scan engine to send the scan requests without waiting for scan responses for previous scan requests.

Storing scan requests for fast preparatory scans of an asset

Various embodiments include systems and methods of implementing automated assessment scheduling. A set of scheduling parameters may be received, including at least a frequency corresponding to how often assessments are to be completed via a particular automated assessment and a type of assessment to perform in the particular automated assessment. Based at least in part on the set of scheduling parameters, an assessment configuration may be generated. The assessment configuration includes a set of attributes defining how the particular automated assessment is to be performed. At least one scan engine resource of a set of scan engine resources may be identified for utilization in the particular automated assessment. Based at least in part on the assessment configuration and using the at least one scan engine resource, the particular automated assessment may be automatically initiated.

Automated assessment scheduling

Asynchronous protocol for assessment of network system assets

A method for asset assessment is provided. The method includes receiving, by a scan engine, an event message from a scan assistant associated with an asset of a network system. The asset includes at least one computing resource. The event message includes an indication of one or more events associated with the asset. The method also includes responsive to receiving the event message, transmitting, by the scan engine, a request to the scan assistant for executing one or more scan operations on the asset and to determine a state of the asset based on at least one of an amount of available network resources or a schedule associated with the asset. The method further includes executing, by the scan engine, the one or more scan operations on the asset after transmitting the request.

Event-driven assessment of network system assets

A software agent executing on a computing device receives a high-level command from a client and converts the high-level command into multiple low-level commands. The software agent executes individual low-level command on the computing device and sends a result of executing the individual low-level command to the client until each low-level command has been executed.

Authenticated assessment of network system assets

Various embodiments include systems and methods of automated scan engine assignment. Responsive to determining to initiate a scan of a target asset, a scan engine assignment strategy may be determined for automatically assigning one or more scan engines to perform the scan. Determining the scan engine assignment strategy may include implementing a strategy selection scheme that defines a hierarchy of scan engine assignment strategies, which may include at least one of a passive discovery strategy, an active discovery strategy, or a scan engine subnet strategy. Using the scan engine assignment strategy, the one or more scan engines may be automatically assigned to perform the scan. The scan may be performed using the one or more scan engines.

Automated scan engine assignment

Various embodiments include systems and methods of implementing automated assessment scheduling. A particular automated assessment may be automatically performed based at least in part on an assessment configuration and scan engine resource(s) of an organization. Based at least in part on performance of the particular automated assessment, a scan engine utilization assessment may be performed to determine a scan engine utilization value that represents utilization of the scan engine resource(s) with respect to resource requirements that are based at least in part on the set of attributes of the assessment configuration. Based at least in part on the scan engine utilization assessment, a particular resource utilization recommendation may be generated. The particular resource utilization recommendation may correspond to a first resource utilization recommendation to allocate additional scan engine resources or a second resource utilization recommendation to allocate fewer scan engine resources.

Various embodiments include systems and methods to implement network scanner timeouts based at least in part on historical network conditions. The implementing comprises initiating, using one or more network scanners and according to a first set of timeout parameters, a first security assessment of one or more scan targets in a network, wherein the first set of timeout parameters comprises a first initial round trip time (RTT)-timeout parameter value to which a dynamic RTT-timeout value is initially set. The implementing comprises determining a first set of RTT statistics for the first security assessment. The implementing comprises determining, based at least in part on the first set of RTT statistics, a second set of timeout parameters for a second security assessment of the one or more scan targets. The implementing comprises initiating, according to the second set of timeout parameters, the second security assessment of the one or more scan targets.

Network scanner timeouts

Methods, systems, and processes to simplify networking setup complexity for security agents implemented in cybersecurity computer environments are disclosed. A request with an intentionally bad Transport Layer Security (TLS) handshake is transmitted from an agent to a server. An indication is received from the server that the request has been rejected. A Round Trip Time (RTT) of the request and rejection of the request is determined. The server is then pinged based on the RTT. The subsequent pinging does not require whitelisting of an additional port and does not negatively interact with network intermediaries that support protocol detection.

Simplifying networking setup complexity for security agents

Methods and systems for managing data transmissions. The methods disclosed herein may involve receiving requests for a first and a second service, and routing communications with the second service through the first service without requiring the firewall to be reconfigured to allow communications with the second service.

Secure multiplexed routing

Disclosed herein are methods, systems, and processes for implementing a single whitelisted ingress endpoint on both one-way and two-way Transport Layer Security (TLS) connections and performing load balancing. Both two-way TLS agent-based traffic and one-way TLS non-agent-based traffic is routed through a single whitelisted internet protocol (IP) endpoint. A TLS connection is transmitted from a network load balancer and to a platform gateway service that operates as a Server Name Indication (SNI) reverse proxy server. The platform gateway service separates out the one-way TLS non-agent-based traffic that is part of the TLS connection based on a TLS header of the TLS connection. The one-way TLS non-agent-based traffic is then selectively terminated on an elastic load balancer.
