Security issues in software engineering Software development security issues Security threat models Security Architecture Designing with security in mind Security components and techniques Programming secure software Most dangerous errors

Legacy Systems Software component reuse Designing software systems for change Modular/replaceable components Designing software systems for reuse Legacy code Generating requirements, documentation, models, etc. Modifying Testing Dependencies

Software System Performance 1 When and how performance matters in computer systems High performance computing HPC vs HTC Performance challenges for software systems Bottlenecks Timescales of components Utilization of different components Predicting system performance Simulations Direct measurement Fixing poor performance Software performance requirements documentation

Software System Performance 2 Analyzing system performance Performance engineering motivation Performance metrics Performance engineering documentation Requirements Functional specifications Design specifications

Usability and user interface 1 Importance and development of user interfaces Mock up, wire frames, focus groups Usability requirements Accessibility Equipment Mental models Interface functionality UI design GUI Command line Help systems

Usability and user interface 2 Four computing eras HCI architectures Unimodal Multimodal Usability goals Usability design Users with disabilities Elderly users children

Software Reliability Reliability terminology Failure, fault, error, fault avoidance/detection/tolerance Software vs. hardware reliability Software reliability modeling Software reliability metrics

Software testing 1 Testing strategies Levels of testing General characteristics Verification and validation Levels of testing Unit testing Interface, data structurers, boundaries, basis paths, error handling Integration testing Non-incremental, incremental Validation testing Based on requirements System testing Regression testing Smoke testing Error discovery and handling debugging

Software testing 2 Static verification testing Program inspections Data, control, I/O, interface, storage, exceptions Dynamic verification testing Interface Parameters, shared memory, message passing protocols Unit testing: Basis paths Flow graphs, cyclomatic complexity, basis set, test cases Integration testing Performance/stress testing Acceptance testing

Acceptance testing Acceptance Criteria Acceptance Testing Approach Iterative/Incremental/Sequential Acceptance Test Reports/Documentation Delivery of Software
