Unit 10: Databases Security

10.3 Mobile Databases Security Notes

A mobile database is said to be a database that can be associated to by a mobile computing
device over a mobile network .The client and server contain wireless connections. A cache is
sustained to hold recurrent data and transactions so that they are not lost because of connection
failure. A database is a structured manner to organize information. This could be a list of
contacts, price information or distance travelled. The utilization of laptops, mobiles and PDAs is
growing and possible to augment in the future with progressively more applications locating in
the mobile systems. While those similar analysts can’t tell us precisely which applications will
be the most well-liked, it is obvious that a large percentage will need the use of a database of
some class. Many applications like databases would need the ability to download information
from an information storehouse and function on this information even when out of range or
detached.

Example: An example of this is a mobile workforce. Here user would need to access and
modernize information from files in the home directories on a server or customer proceedings
from a database. This sort of access and work load produced by such users is dissimilar from the
traditional workloads observed in client–server systems of today.
With the arrival of mobile databases, now users can load up their smart phones or PDAs with
mobile databases to substitute mission-critical data distantly without distressing regarding
time or distance. Mobile databases allow employees to enter data on the fly. Information can be
harmonized with a server database later on.
With the growth in popularity of smartphones has come an increasing requirement to secure
them. As their introduction mobile phones have becoming risingly smaller, more strong with
rising storage potential and have remained costly items. With the rise of their popularity so has
the requirement to protect the devices from theft in addition to traditional threats that effect
computers like malware and the requirement to back and protect the data on the devices.

Database security is also an expertise within the broader discipline of computer security. For
many businesses applications are going mobile that signifies using enterprise data in mobile
context, therefore using a mobile DBMS. With these new enhancements the business data of an
enterprise can be made obtainable to an even larger number of users and a broader range of
applications than before. To function on business data anytime and anywhere is the major
objective pursued by developing mobility assistance in database context. The confidentiality of
mission-critical data must be assured, although most mobile devices do not offer a secure
surroundings for storage of such data. Security needs that apply to a central company database
should apply identically and in a proper manner to the parts of the database replicated on
mobile devices in the field. A mobile database security infrastructure is required to fulfill this
goal. When producing such an infrastructure, we can benefit from the consequences of traditional
database security work. But we also require to adapt the current techniques and approaches to
the mobile context, and we require to produce new ones that attack some issues particular to use
of database systems in mobile environment.
The need of databases in contemporary businesses and governmental institutions is enormous
and still mounting. Many mission-critical applications and business processes depend on
databases. These databases enclose data of different amount of significance and discretion, and
are used by a broad variety of users. Integrity violations for a database can have severe impact
on business processes; revelation of confidential data in some cases has the similar effect.
Traditional database security offers techniques and approaches to manage such problems with
respect to database servers in a non-mobile context.
