Answer:
MS access objects help the user list , information and designed reports .
Explanation:
MS access objects are create a forms, data base, tables,queries, and modules. There are many objects are following:-Tables, Forms,Reports, Queries.
Table:- These are objects used into a define and store the data,tables are contain the columns and the store of different data.
Form:- Form is the object that designed by the data input and control application queries or tables, forms are used in viewing records.
Reports:- Reports are the designed to the printing and calculating data,reports are used because data in read to easy format.
Queries:- Queries are provides that data from one or more table,you can define the update ,delete, insert, select data.
Answer:
The answer is by using a covert channel like shared memory objects such as files, directories,messages, etc since both the user and the sender of the document are on same network of the company.
Explanation:
The Bell LaPadula MultiLevel Security model was a security policy developed by Bell and LaPadula in 1973 in response to a security issue raised by the US Air Force regarding file-sharing mainframe computers . Actually, many people with networked systems have realized by early 1970s that the protection purportedly offered by many commercial operating systems was poor, and wa not getting better any time soon. This was observed when it was noticed that as one operating system error was fixed, some other vulnerability would be discovered. There was also the constant worry that various unskilled users would discover loopholes in the operating system during usage and use them to their own advantage.
Information release may take place via shared memory objects such as files, directories, messages, and so on. Thus, a Trojan Horse acting on behalf of a user could release user-private information using legitimate operating system requests. Although developers can build various mechanisms within an operating system to restrict the activity of programs (and Trojan Horses) operating on behalf of a user , there is no general way, short of implementing nondiscretionary policy models, to restrict the activity of such programs. Thus, given that discretionary models cannot prevent the release of sensitive information through legitimate program activity, it is not meaningful to consider how these programs might release information illicitly by using covert channels.
For example, for someone with higher integrity level (SECRET) to send an accounts payable application to a user, if the untrusted accounts payable application contains a Trojan Horse, the Trojan Horse program could send a (legal) message to the said user process running at a lower integrity level (CONFIDENTIAL), thereby initiating the use of a covert channel. In this covert channel, the Trojan Horse is the receiver of (illegal) lower integrity-level input and the user process is the sender of this input.
Answer and Explanation:
Virtual machine have one imitated organize connector and there is one of a kind MAC address is allocated with it.
The system driver of the Virtual machine's performs all the task:
-
The system driver places physical connector in 'promiscuous' mode implies physical connector will acknowledge all system parcel paying little heed to MAC address,then virtual machine's driver channels its bundles and direct it to the virtual machine.
