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.

Answer: well there are many types of software out there and let's use Microsoft for an example there a really protective company so more people would want to buy from Microsoft they have a lot of high-tech computers so and I'm not favoriting Microsoft it's just what I've use Chrome also is really good but you would kind of want to go off like reviews that you see and everything like that because I'm not a big computer tech but that's just what I know

Answer:
There is no direct return on investment in building security systems.
Security systems are detrimental to usability and can make IT systems less functional, and therefore less attractive to the customer.
There is pressure to reduce the time it takes to get a new IT product or system onto the market, so security systems are sacrificed in order to reduce the time-to-market.
Explanation:
Cyber security has always been challenging for the organizations. There have been groups which are always looking for loop holes in cyber security and hacks the details and asks the ransom to restore. IT systems have now been more complex in this era. Users are increasing every new day and network accounts security is more demanding. Computer connection are more complex and require special attention to control them. The obstacles in IT systems are of concern as there is need for dynamic IT solution to counter the challenging hackers. New programs and customized demand of IT systems need customized IT security systems.
