Abstract: Methods, systems, and computer-readable media for automated packetless network reachability analysis are disclosed. An analysis is performed of network configuration data for a network comprising a host computer. Based at least in part on the analysis, one or more ports at the host computer that are reachable from another computer are determined. Based at least in part on the analysis, one or more routes to the one or more ports are determined. A report is generated that is descriptive of the one or more ports and the one or more routes.

Abstract: A method for verifying source code for a program includes determining that a new version of the source code is available. One or more verification tools are determined to use for verification of the new version of the source code from a verification specification associated with the source code. A plurality of verification tasks to perform for the verification of the new version of the source code are automatically determined from the verification specification associated with the source code. The plurality of verification tasks for the new version of the source code are automatically performed using the one or more verification tools. A determination is then made as to whether the new version of the source code is verified.

Abstract: Methods, systems, and computer-readable media for analysis of role reachability using policy complements are disclosed. An access control analyzer determines two nodes in a graph that potentially have a common edge. The nodes correspond to roles in a provider network, and the roles are associated with first and second access control policies that grant or deny access to resources. The access control analyzer performs a role reachability analysis that determines whether the first role can assume the second role for a particular state of one or more key-value tags. The role reachability analysis determines a third access control policy authorizing a negation of a role assumption request for the second role. The role reachability analysis performs analysis of the third access control policy with respect to a role assumption policy for the second role for the particular state of the one or more key-value tags.

Abstract: Techniques for intent-based governance are described. For example, in some instances a method of receiving an indication of a change involving of one or more of code, a policy, a network configuration, or a governance requirement rule impacting a resource in a provider network for an account that is to be analyzed using one or more governance requirement rules; determining one or more governance requirement rules to evaluate for compliance after the update; evaluating the determined one or more governance requirement rules for compliance using one or more reasoning engines according to one or more policies; and making a result of the evaluating available to a user provides such governance.

Abstract: Techniques are described for efficiently distributing across multiple computing resources satisfiability modulo theories (SMT) queries expressed in propositional logic with string variables. As part of the computing-related services provided by a cloud provider network, many cloud providers also offer identity and access management services, which generally help users to control access and permissions to the services and resources (e.g., compute instances, storage resources, etc.) obtained by users via a cloud provider network. By using resource policies, for example, users can granularly control which identities are able to access specific resources associated with the users' accounts and how those identities can use the resources. The ability to efficiently distribute the analysis of SMT queries expressed in propositional logic with string variables among any number of separate computing resources (e.g., among separate processes, compute instances, containers, etc.) enables the efficient analysis of such policies.

Abstract: A policy auditing service can be implemented, in accordance with at least one embodiment that obtains a set of parameters that indicates a snapshot of a policy configuration for an account, a query, and a security policy. The security policy may encode a security requirement or invariant. The policy auditing system may determine states that can be reached via mutative operations (e.g., role assumption) and use a policy analyzer service to determine whether assuming a role results in a grant of access that is at least as permissive as the security policy of the set of parameters.
