Techniques for more precise access control policy findings, use a conditional injection of policy constraints into a findings analysis. The injection of a policy constraint of a policy being analyzed into the findings analysis is conditioned on the policy itself. In particular, the injection is conditioned on whether the policy constraint is trusted in the context of the policy (e.g., unlikely to be spoofed or manipulated in the policy context). As a result, where a policy constraint can be trusted in the context of a given policy, a more precise (e.g., more specific) findings analysis of the policy based on the policy constraint can be conducted than if the policy constraint were not included in the policy finding analysis (e.g., because the policy constraint is not trusted in other policy contexts).

The present disclosure is related to a concept for providing conditional access to an online service. A smart contract deployed on a blockchain network is used to lock a predetermined amount of digital assets of a user for a predetermined locking duration. A proof is provided to the online service that the user has locked an amount of digital assets meeting or exceeding a threshold specified by the online service. The proof is verified and access for the user to the online service may be granted in case the verification is successful.

In a cloud computing environment, cross-tenant access security measures include monitoring a change or addition of conditional access policies that impedes or is at risk to impede authorized access to a focal tenant from a secondary tenant user. In some cases, cross-tenant access security includes tracking a role assignment list to detect malicious roles, or to detect hindered role changes such as role deletion, or both. In some cases, focus tenant events and auxiliary tenant events are associated in the audit. In some cases, the authorized access is an access when zero persistently limited. In some cases, authorized access is constrained to an IP address range, or to a login from a managed device, or both. In short, security measures are described that aim to mitigate accidental or secret role or policy changes that may interrupt or obstruct authorized cross-tenant access.

Methods and systems for enabling conditional access to a resource, where the condition is the performance of a task. This task can be executed by one party on behalf of another. The entity controlling access creates a task that includes broadcasting a transaction on the blockchain, with multiple outputs, including a locking-output. Additional transactions ensure access to the resource only upon task completion. Access is achieved by initially broadcasting the resource, conditionally available, then broadcasting the transaction that fulfills the condition. Multi-signatures and a refund mechanism are used to lock access, with multi-signatures spread across transactions. Initial deposit broadcast makes the resource available but locked by a first multi-signature and tied to a refund mechanism. The task and transaction have a locking-output secured by a second multi-signature linked to the refund mechanism. Access requires both multi-signatures of the refund mechanism to be signed and the main transaction to be broadcast.

This disclosure describes techniques for enforcing conditional access to network services. In an example method, a first computing device detects a second device operating in a per-flow authorization mode. The first device receives a first request from a second computing device to communicate with a third computing device using a first network flow and determines that the first flow is authorized (e.g., because of an active past authentication and / or the third device's authentication exemption). Data associated with the first request is transmitted to the third device. The first device then receives a second request to communicate with a fourth computing device using a second network flow and determines that the second flow is not authorized (e.g., because it is not associated with an active past authentication and / or the fourth device is not exempt from authentication). Data associated with the second request is not transmitted to the fourth device.
