Information Assets Protection

Biometric Technology - Part IV

Technology attacks and attendant security compromises are never easily managed. Parallel to the ingenuity of attackers and proportional to the value placed on entrusted information assets, effective security access controls are imperative. Given the current accuracy of automated user identification and authentication processes, no single security system should ever be promoted as infallible. However, there is sufficient merit in most available biometric systems to warrant deployment consideration for information assets protection. Coupled with other access restriction techniques, biometric technology systems can be a formidable deterrent to unauthorized activities that may disable an entity’s information security infrastructure.

Through the identification or authentication process, decisions are made regarding access. Typically, biometric identification supports physical access controls, while biometric authentication supports logical access controls. With reliance on biometrics for asset protection, security managers must accept humanness features are dynamic, yet reproducible. Consequently, it is difficult to find a single perfect access security system employing physical and/or behavioral traits.

Voices change over time or under abnormal conditions and can be modulated. Handprints can be altered — by a cut or bruise — as well as replicated. Even eyes and ears can undergo biological transformation from one day to the next. Furthermore, behaviors can be affected by emotional or fatigue states. Thus, biometric systems developed for identifying and/or authenticating authorized users that eliminate all potential errors can be prohibitively time-consuming and expensive, especially in high-traffic areas.

Most information security practitioners accept biometrics as the science employing distinctive human attributes to discern access right validity. Specifically, imparting the Information Systems Audit and Control Association’s definition, biometrics is the process for identifying or authenticating a living person’s identity based on physiological or behavioral characteristics. Delineated, biometrics identification usually involves a one-to-many individual characteristics search utilizing linked data repositories; whereas biometric authentication entails establishing a one-to-one relationship verifying the claim to an identity made by an individual.

As technological advancements are increasingly immersed in routine human endeavors, few security professionals doubt the criticality for parallel and proportional achievements in information asset protection mechanisms to defend against threats from individuals or groups chasing infamy dreams. Contextually, those engaged in nefarious IT activities vigorously pursue stardom elevation by orchestrating information security attacks that render barriers to obtaining or affecting a targeted object impotent. When an information asset is deemed valuable, authorization through a single access scheme appears woefully inadequate compared to the estimated number of ‘hackers’ or ‘crackers’ probing IT operational defenses. Predictively, considering published organizational information security incidents, two or more authentication factors will inevitably become the security deployment norm, with one architectural authentication factor relying on a biometrically based process; unless superior alternative access control remedies are devised.
