Abstract-Mission critical information systems must be certified against a set of security controls to mitigate potential security incidents. Cloud service providers must in turn employ adequate security measures that conform to security controls expected by the organizational information systems they host. Since service implementation details are abstracted away by the cloud, organizations can only rely on service level agreements (SLAs) to assess the compliance of cloud security properties and processes. Various representation schema allow SLAs to embed service security terms, but are disconnected from documents regulating security controls. This paper demonstrates an extensible solution for building a compliance vocabulary that associates SLA terms with security controls. The terms allow services to express which security controls they comply with and enable at-a-glance comparison of security service offerings so organizations can distinguish among cloud service providers that best comply with security expectations. To exemplify the approach, we build a sample vocabulary of terms based on audit security controls from a standard set of governing documents and apply them to an SLA for an example cloud storage service. We assess the compatibility with existing SLAs and calculate the computational overhead associated with the use of our approach in service matchmaking.

“…While there are technologies for composing SLAs in XML-based representations, e.g. WSLA [12], these embed domain-specific terms; no terms for resource reservation have yet been proposed within the Grid community. In any case, it is certain that SLAs can be designed to include acceptable start and end time bounds and a simple description of resource requirements.…”

Abstract. In this paper we propose a new infrastructure for efficient job scheduling on the Grid using multi-agent systems and a Service Level Agreement (SLA) negotiation protocol based on the Contract Net Protocol. The agent-based Grid scheduling system involves user agents, local scheduler agents, and super scheduler agents. User agents submit jobs to Grid compute resources. Local scheduler agents schedule jobs on compute resources. Super scheduler agents act as mediators between the local scheduler and the user agents to schedule the jobs at the global level of the Grid. The SLA negotiation protocol is a hierarchical bidding mechanism involving meta-SLA negotiation between the user agents and the super scheduler agents; and sub-SLA negotiation between the super scheduler agents and the local scheduler agents. In this protocol the agents exchange SLA-announcements, SLA-bids, and SLAawards to negotiate the schedule of jobs on Grid compute resources. In the presence of uncertainties a re-negotiation mechanism is proposed to renegotiate the SLAs in failure.

It owns an asymmetric model and there is no optimation of the selection because search results are only the lists of conformant offers.…”

Abstract. As government agencies and business become more dependent on web services, software solutions to automate their procurement gain importance. Current approaches for automating the procurement of web services suffer from an important drawback: neither uncertainty measures nor non-linear, and complex relations among parameters can be used by providers to specify quality-ofservice in offers. In this paper, we look deeply into the roots of this drawback and present a proposal which overcomes it. The key point to achieve this improvement has been using the constraint programming as a formal basis, since it endows the model with a very powerful expressiveness. A XML-based implementation is presented along with some experimental results and comparisons with other approaches.
