Whitelist
A whitelist, allowlist, or passlist is a mechanism which explicitly allows some identified entities to access a particular privilege, service, mobility, or recognition i.e. it is a list of things allowed when everything is denied by default. It is ...
ing: Programs are first checked against a list of known trusted and validated applications and files. These "whitelisted" files are allowed to run without restriction.

Blacklisting
Blacklisting is the action of a group or authority compiling a blacklist (or black list) of people, countries or other entities to be avoided or distrusted as being deemed unacceptable to those making the list. If someone is on a blacklist, t ...
: Only if programs are not present on the whitelist are they then checked against an updated database list of virus signatures; those files whose MD5 signature is on the list are automatically moved to quarantine area if they attempt to gain access to system or data. This is technique as used by practically all antivirus products as the first line of defense.

Heuristics
A heuristic (; ), or heuristic technique, is any approach to problem solving or self-discovery that employs a practical method that is not guaranteed to be optimal, perfect, or rational, but is nevertheless sufficient for reaching an immediate, ...
If the programme is not on either list its behavior is compared to that of previous encountered malware.
# Community Statistics: DriveSentry also collects and stores user statistics based on access decisions made by the user, which is shared amongst all other users.
DriveSentry partners with Offensive Computing and Frame4 Security Services to collect and analyze malware samples for the database list, partnering in this way ensures that the database is fed by multiple sources and therefore offers redundancy.
Although DriveSentry's basic features are available for free, its more ''advanced features'' such as automatically updating its white and blacklists have to be paid for via a one-off payment.

However, this functionality does come at a cost – specifically, whitelisting only allows pre-vetted software to be executed, and prevents all other software from running, even if it is harmless. DriveSentry avoids this issue by allowing the user to be prompted if programs don't appear in the black or whitelist. This then forces responsibility on the end user to determine what is good or bad. DriveSentry attempts to help the user by monitoring the action of the program and calculating and displaying a threat rating.
Furthermore, malicious software which has been included on the whitelist can still be executed.
