SecMusings is the weblog where Andy Sherman discusses technology and security. Andy is currently an independent information technology consultant, although a full-time job would always be welcome. He has a PhD in Physics and started his 30-year career in the academic world. He then went to AT&T Bell Laboratories where he discovered the power – and hazards – of large distributed computer networks. It was also at Bell Labs, during the early days of the Internet, that Andy became interested in the security problems associated with public networks. From Bell Labs Andy moved to the financial services industry. There he worked on a large range of infrastructure design, deployment, and management projects, but is best known for his almost 15 years in information and technology security.
