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:
The correct answer to the given question is option D) Any or all of the above.
Explanation:
A posting error is a type of error which is related to ledger and would include the errors like -
Posting wrong amount on the right side of account
Posting right amount on the wrong side of right account
Posting an amount twice and posting omission
Posting wrong amount to wrong side of right account
Posting correct amount on wrong account on right side
So by knowing all the given above points, it is quite clear that the correct option is D.
Answer:
True
Explanation:
Rootkits are malicious software that allows an unauthorized user to access a computer and restricted areas of software. Rootkits are difficult to detect on your computer because it may be able to subvert there that is intended to find it. Rootkits are created by Black-hat hackers to attack your computer and steal.
Rootkit tools:
1. Keyloggers
2. antivirus disablers
3. password stealers
4. banking credential stealers
5. bots for DDoS attacks

that is technical but I will go with all I mean d
The limit for file names on modern file systems is usually at least 255 bytes.
