Solution:
The process of transaction can guarantee the reliability of business applications. Locking resources is widely used in distributed transaction management (e.g; two phase commit, 2PC) to keep the system consistent. The locking mechanism, however, potentially results in various deadlocks. In service oriented architecture, the deadlock problem becomes even worse because multiple transactions try to lock shared resources in the unexpectable way due to the more randomicity of transaction requests, which has not been solved by existing research results. In this paper, we investigate how to prevent local deadlocks, caused by the resource competition among multiple sub-transactions of a gl obal transaction, and global deadlocks from the competition among different global transactions. We propose a replication based approach to avoid the local deadlocks, and a timestamp based approach to significantly mitigate the global deadlocks. A general algorithm is designed for both local and global deadlock prevention. The experimental results demonstrate the effectiveness and efficiency of our deadlock prevention approach. Further, it is also proved that our approach provides higher system performance than traditional resource allocation schemes.
This is the required answer.
Answer:
Data is encrypted on SSH
Explanation:
Telnet and SSH both are the networking protocols. These protocol are used for the security of data. In telnet data is sent over the link without any encryption. That is the reason, in telnet protocol data is less secure.
In SSH (Security Shell) protocol data has been encrypted before transmission. The encryption of data make it more secure between transmitter and receiver.
So the true statement is that, SSH has data encryption.
Answer:
3,265,920 unique ID exist.
Explanation:
The nine digits are from 0 to 9, there are ten bits from 0 -9,
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
The first is select from the highest bit (9), and the second is selected at random from 0 - 9, the third bit to the last must be unique and different from each other;
number of unique IDs = 9 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2
Multiplying the nine bits of unique IDs = 3,265,920.
A Design Basis Threat (DBT) is known to be a characteristics of any given or potential insider and also those of external adversaries, that may try to have or gain unauthorized removal or sabotage, against a physical protection system that was set up designed and evaluated.
<h3>What are Cybersecurity objectives?</h3>
Cybersecurity aims are:
- To protect computer system,
- To protect networks,
- To protect software programs from such cyber attacks.
Note that a lot of digital attacks are targeted at accessing, changing, or deleting sensitive information as well as others.
