Introduction to Hardware Security and Trust,

Test interfaces are present in nearly all digital hardware. In many cases, the
security of the system depends on the security of the test interfaces. Systems have
been hacked in the field using test interfaces as an avenue for attack. Researchers
in industry and academia have developed defenses over the past 20 years. A diligent
designer can significantly reduce the chance of system exploitation by
understanding known threats and applying known defenses.
