Activated human neuropeptide Y Y(1) receptors rapidly desensitize and internalize through clathrin-coated pits and recycle from early and recycling endosomes, unlike Y(2) receptors that neither internalize nor desensitize. To identify motifs implicated in Y(1) receptor desensitization and trafficking, mutants with varying C-terminal truncations or a(More)
—Systematic and practical approaches to risk-driven operational security evidence help ensure the effectiveness and efficiency of security controls in business-critical applications and services. This paper introduces an enhanced methodology to develop security effectiveness metrics that can be used in connection with correctness assurance of security(More)
Assurance is commonly considered as “something said or done to inspire confidence” (Webster dictionary). However, the level of confidence inspired from a statement or an action depends on the quality of its source. Similarly, the assurance that the deployed security mechanisms exhibit an appropriate posture depends on the quality of the verification process(More)
Measurement of any complex, operational system is challenging due to the continuous independent evolution of the components. Security risks introduce another dimension of dynamicity, reflected to risk management and security assurance activities. The availability of different measurements and their properties will vary during the overall system lifecycle.(More)
Today's IT systems are ubiquitous and take the form of small portable devices, to the convenience of the users. However, the reliance on this technology is increasing faster than the ability to deal with the simultaneously increasing threats to information security. This paper proposes metrics and a methodology for the evaluation of operational systems(More)
