Optimal Software Patching Plan for PMUs
Phasor measurement units (PMUs) deployed to monitor the state of an electrical grid need to be patched from time to time to prevent attacks that exploit vulnerabilities in the software. Applying some of these patches requires a PMU reboot, which takes the PMU offline for some time. If the PMU placement provides enough redundancy, it is possible to patch a set of PMUs at a time while maintaining...
متن کاملOptimal Software Release Time with Patching Considered
Optimal software release policy is a well studied topic in the software reliability literature. However, all existing studies implicitly assume that testing stops at the time of release. Due to the advances in data communication technologies, an increasing number of software producers are providing patches for software defect correction and updates subsequent to a version release. Based on this...
متن کاملOptimal Patching Schemes for Efficient Multimedia Streaming
Multimedia streaming applications consume a significant amount of server and network resources due to the high bandwidth and long duration of audio and video clips. Making streaming services economically viable requires techniques for minimizing the incremental cost of serving a new client, particularly for popular content. Patching [1] reduces server and network overhead by allowing a client t...
متن کاملOptimal Patching in Clustered Epidemics of Malware
Studies on the propagation of malware in mobile networks have revealed that the spread of malware can be highly inhomogeneous across different regions. Heterogeneous rates of contact can also be due to diverse platforms, utilization of contact lists by the malware, the clustered nature of the network, etc. In this paper, a general formal framework is proposed for leveraging such information abo...
متن کاملImpact of Patching on Software Quality
W present a model of fixing or patching a software problem after the product has been released in the market. Specifically, we model a software firm’s trade-off in releasing a buggy product early and investments in fixing it later. Just as the marginal cost of producing software can be effectively zero, so can the marginal cost of repairing multiple copies of defective software by issuing patch...
