A system of module coatings can provide either high or low levels of physical security for personal computers. To eliminate the security vulnerability of conventional computer modules, coatings may be applied which offer repairability with tamper- detection features for low security protection. These coating include silicone, acrylic and ultraviolet (UV) adhesives. For a higher level of security which sacrifices repairability, a coating may be applied which cannot be removed without damage to the underlying module and chips. These coatings include epoxy and parylene. As a rule, increasing the security offered by a coating decreases the repairability. Silicone and acrylic coatings are primarily environmental coatings which can be used in conjunction with other materials to produce a security coating.
