Abstract: Systems and methods for restricting access to infrastructure components are provided. In this regard, a representative system includes: a lock assembly having a receptacle, a sleeve, a fastener and a cap; the receptacle having a longitudinal bore; the sleeve defining an interior and having a first end, an opposing second end, and an interior flange positioned between the first end and the second end; the fastener having a shaft extending from a head, the shaft being sized and shaped to engage within the longitudinal bore of the receptacle, the head being sized and shaped to prevent passage of the fastener through the sleeve via interference with the first flange; the cap being operative to engage the second end of the sleeve such that, in an engaged position, the cap and the sleeve retain the head of the bolt within the interior of the sleeve; the lock assembly being operative to selectively secure the lid to the housing.
