how to be a better seal user (2003)
Tamper-indicating seals have been used for over 7,000 years. Today, seals are widely used to help counter cargo theft, smuggling, sabotage, vandalism, tampering, terrorism, and espionage. Despite their antiquity and modern widespread use, however, there remains considerable confusion about
seals, as well as a lot of misconceptions, wishful thinking, sloppy terminology, and poor practice.
The Vulnerability Assessment Team (VAT) at Los Alamos National Laboratory has intensively studied tamper-indicating seals for the last 12 years. We have provided consulting, vulnerability assessments, and security solutions for over two dozen government agencies and private companies. This article summarizes some of our recommendations for using seals more effectively and with greater sophistication.
