of the current system state is taken and according to your configuration Verisys will automatically compare the system against this baseline to detect any changes. Using the console, you can also start an integrity check manually at any time.
The Verisys agent examines a number of properties and attributes of each file to ascertain whether any changes have been made. Rather than simply check basic object properties, Verisys performs a cryptographic hashing algorithm
on the actual data contained within each file.

Verisys consists of both clientClient (computing)
A client is an application or system that accesses a service made available by a server. The server is often on another computer system, in which case the client accesses the service by way of a network....

Server (computing)
In the context of client-server architecture, a server is a computer program running to serve the requests of other programs, the "clients". Thus, the "server" performs some computational task on behalf of "clients"...

Gui
Gui or guee is a generic term to refer to grilled dishes in Korean cuisine. These most commonly have meat or fish as their primary ingredient, but may in some cases also comprise grilled vegetables or other vegetarian ingredients. The term derives from the verb, "gupda" in Korean, which literally...

How it Works
A baseline snapshotSnapshot (computer storage)
In computer systems, a snapshot is the state of a system at a particular point in time. The term was coined as an analogy to that in photography. It can refer to an actual copy of the state of a system or to a capability provided by certain systems....

Cryptographic hash function
A cryptographic hash function is a deterministic procedure that takes an arbitrary block of data and returns a fixed-size bit string, the hash value, such that an accidental or intentional change to the data will change the hash value...
