There are various security approaches for mobile database environment which are as follows −Transparencies − There are basic security challenges tightening up because of mobility. It contained in these challenges is the dispute of transparencies, the transparency in the database sense against the transparency in the privacy sense. The first define the user will be satisfied from internal system knowledge.Secure Locations and Movements − The location is a sensible data only in connection with customer identities. The best protection of user whereabouts consists in the prevention of management of location information or user information, correspondingly. Movement information can be achieved ... Read More

There are some security issues in mobile database environment which are as follows −Data Security in mobile data transfer − Disconnections appear of ten in wireless communication. They can be forced by the user because of storing communication costs or be persuaded by faults. This situation can expose the data consistency, even without considering replicas. Disconnections are basically a problem of the fundamental layers of a database, but the database system is also answerable for preventing data loss in case of such unexpected disconnections with the help of transaction recovery.Metadata Security in mobile data transfer − It includes a user ...

There are several issues in in multilevel security based on distributed security manager which are as follows −Authentication − User authentication is the basic line of defence for mobile and handheld devices including Personal Digital Assistants (PDAs). Traditional authentication structure rely on supporting a centralized database of user identities, making it complex to authenticate users in a different management domain as depicted.This mechanism for supporting security in mobile device is a difficulty for each system supporting safe access to precious, private data, or personalized services. The authentication structure should be distributed, and the several components of the authenticator need to ... Read More

There are various techniques of database security which are as follows −Secure network connection − The mobile database and the main database have to be synchronized at definite times. The synchronization is performed in the system software of the mobile database and is implemented over the http protocol.Encrypted local database − The local database on the mobile device is encrypted and every time the user opens the mobile database, it has to enter his password. In case the mobile device is taken or broken by an intruder, the data that is stored on the local database is not understandable. The ... Read More

There are various strategy of mobile database system which are as follows −Perfecting the Authentication Mechanism − It can avoid illegal terminal access deceptively and background information can be damaged, it is required for identity authentication, when mobile user and service database operating synchronous in the mobile database system.When it required to connect or disconnect mobile user, the mobile database needs to carry on identity verification itself, because the users input their user name and password, so can query, change the local caching after verification in mobile user. But the mobile user is needed to verify identity in the database ... Read More

A mobile database is said to be a database that can be related to by a mobile computing device over a mobile network .The client and server include wireless connections. A cache is maintained to hold recurrent information and transactions so that they are not lost due to connection failure.A database is a structured manner to organize data. This can be a list of contacts, price data or distance travelled. The application of laptops, mobiles and PDAs is increasing and possible to augment in the future with successively more applications locating in the mobile systems.Some applications like databases would require ...

Database security contains securing the database from permitted access, alteration or elimination. Because the database defines an essential corporate resource, database security is an essential subcomponent of some organization’s complete information system security plan.Moreover the requirement to keep and secure information for the smooth services of the organization, database designers have the authority to secure the privacy of individuals about whom data is maintained.Privacy is the right of individuals to have some control over data about themselves. Some countries have laws designed to secure privacy, and each organization that collects and stores data about individually is legally obliged to adopt ... Read More

Database security defines the collective measures used to protect and secure a database or database management software from unauthorized use and malicious cyber threats and attacks. Database security is a layer of information security. It is basically concerned with physical protection of information, encryption of data in storage and data remanence problem.Securing the database is a basic principle for some security workers while mounting the security plan. The database is a compilation of beneficial information and can be treated as the most important constituent of an organization and its economic enlargement.Accordingly, some security effort should remember that they need to ...

Data security defines the process of protecting data from unauthorized access and data corruption throughout its lifecycle. Data security involves data encryption, hashing, tokenization, and key administration practices that secure data across some applications and platforms.Security database professionals have to depend on network management for implementing firewalls or other structure to defend local information as the nature of Intranet/Internet data access is though the database administrator (DBA) has to carry out some security function. This unit will scrutinize the fundamental security areas that fall within the area of the DBA, who then has to create database familiarized solutions.The security of ... Read More

Database security defines the collective measures used to protect and secure a database or database management software from unauthorized use and malicious cyber threats and attacks. There are various principles of database security which are as follows −Security models − A security model creates the external element for the examination of security problems in general, and supports the context for database considerations, such as implementation and operation.Access control − The objective of access control should always be clear. Access control is costly in terms of analysis, model and operational costs. It can be used to known situations, to known standards, ... Read More
