Another significant preferred standpoint of having ODBC as a widespread middleware between an application and a database is that each time the database particular changes, the product does not should be refreshed. Just a refresh to the ODBC driver would be
If a file has been referenced recently, there is a high probability that it will be referenced again soon. These observations were used to guide the design and optimization of AFS, not to restrict the functionality seen by users. • AFS works best with the classes of file identified in the first point above. There is one important type of file that does not fit into any of these classes – databases are typically shared by many users and are often updated quite frequently. Question two: Routing overlay is: A distributed algorithm known as routing overlay, it locates nodes and objects, it is middleware layer responsible for routing requests from clients to hosts that holds the object to which request is addressed.
However, compliance with the PCI DSS standard did not stop the breach. Does compliance ensure security? Compliance and security are two different entities and while being compliant is a byproduct of being secure, the converse is not true. Compliance is the minimum requirement towards security. To be compliant, a self-assessment questionnaire (SAQ) and a vulnerability scan are completed.
While encryption itself doesn’t necessarily prevent data loss, safe harbor provisions in laws and regulations treat lost encrypted on data as not lost at all. The encryption provides resource protection while key management enables access to protected resources. ATTRIBUTE BASED ENCRYPTION (ABE) Attribute based encryption is more suitable for access control to the data stored in the cloud. The main goal for these models is to offer security and access control. The main aspects are to provide flexibility, scalability and fine grained access control.
It allows many users to take advantage of computer’s resources simultaneously. The operating system must keep that point in mind that requirements of the various users are balanced, and each of the programs they are using has enough and independent resources so that a problem with one user does not affect the entire group of users. UNIX, VMS and mainframe operating systems, such as MVS, are examples of multi-user operating systems. It's important to differentiate between multi-user operating systems and single-user operating systems that support networking. Windows 2000 and Novell Netware can each support hundreds or thousands of networked users, but the operating systems themselves aren't true multi-user operating systems.
file based System approach • Advantages of Database Approach i. Control of data redundancy: The database approach attempts to eliminate the redundancy by integrating the file. Although the database approach does not eliminate redundancy entirely, it controls the amount of redundancy inherent in the database. ii. Data consistency: By eliminating or controlling redundancy, the database approach reduces the risk of inconsistencies occurring.
Multi user multi tasking operating system; these operating systems allows multiple users to simultaneous runs applications on a single computer. These operating ensure that the problem with one user does not affect the other by allocating appropriate and separate resources to each user. Example of this operating system is Unix. 4. Real-time operating system; these operating systems interact directly with users and reply in real time or almost immediately with required information.
Garbage collection, exception handling and memory management are some of the features that make java a robust language. Java is a strongly-typed language, which enables extensive compile-time error checking and does not support memory pointers, this eliminates the possibility of overwriting memory and corrupting the data. Java also does automatic memory management, it manages the memory allocation and de-allocation for creating new objects. The program does not have direct access to the memory. The garbage collector automatically deletes objects to which no active pointer
Most popular user interfaces are based on the X Window System, often simply called "X". It provides network transparency and permits a graphical application running on one system to be displayed on another where a user may interact with the application. 3.1.1 Advantages of Linux • Low cost: There is no need to spend time and huge amount money to obtain licenses since Linux and much of its software come with the GNU General Public License. There is no need to worry about any software's that you use in Linux. • Stability: Linux has high stability compared with other operating systems.
DMZ: In computer communications and networks, a DMZ is a small network or computer host that are injected or inserted as a neutral zone between a company’s private network and the outside public network to stop the unauthorized users to getting direct access to the server where company data is stored or available. The term DMZ zone have another meaning, it is a portion of your or anybody network which is although in your or anybody control, is outside heavy security. Once the machine enter the DMZ zone it will never be brought back inside the network again. Assume that it has been fully compromised or negotiated in some way, bring it back in network again is a big security hazard or risk. HISTORY: The De-militarized zone (DMZ) concept was comes
