Description Of A Hat Is Sql? Essay

How : Hackers gained access to the user records in the database by using a password cracking tool. Passwords which were disclosed are weakly encrypted using outdated hashing technique without salting the password and this has made hacker's job easier to convert the encrypted passwords with no less than 2 hours.

Vulnerability 1: Injection – used to attack the applications in which malicious SQL statements are inserted into an entry field for execution.

SQL Injection – an input validation attack specific to database applications where SQL code is inserted into application queries to manipulate the database.

An informatics needs assessment is a critical step in the selection and implementation of the Electronic Health Record (EHR). The purpose of a needs assessment is to understand the organization and the needs of the organization well enough to boost the positive impact of an EHR while minimizing the negative effects (American Medical Association, n.d.).

As the implementation of electronic health records (EHR) progress nationwide, the concepts of interoperability and health information exchange (HIE) must be discussed. The Healthcare Information and Management Systems Society (2005, p. 2) define interoperability as “the ability of health information systems to work together within and across organizational boundaries in order to advance the effective delivery of healthcare for individuals and communities.” Interoperability is the enabling of two systems, including those that do not share

From the above code, we can tell how server send query to Database. But we can still guess to login without knowing the user’s passward by typing “bob’);-- “( space after the comment’--’ )

“Branch Locator” page is vulnerable to SQL injection attacks. This is a serious vulnerability which involves inserting malicious SQL statements into an input field for execution. By appending SQL statements to the URL of the Branch Locator page, information about the structure of the underlying database was collected. This information was then used to generate further malicious statements. The list of database objects, tables and columns were returned. The

The responsibility of a database administrator is to serve as the link between the database designers, knowledge managers and users. The database designers are often brought in for completing specific projects and then moving onto other projects at other companies or different departments at the same company. Their job are usually finished when they finish designing the database. While they may be used in the future to perform some

Computer viruses are minute program which is “embedded inside an application or within a data file which can copy itself into another program“(Adams et al, 2008 ) for the sole determination of meddling with normal computer operations. The consequences may range from corruption and deletion of data; propagation of virus on to network and deployment through attachments through emails in order to further creating havoc to all associated computing devices.

Three types of maintenance plans include: preventative, corrective, and adaptive maintenance which improve the data quality. Activities to improve data quality include database backups, integrity checks, optimizing the index. Preventative maintenance incorporates creating and continuously maintaining daily and/or weekly backups for data loss prevention, corrective maintenance ensures system errors are corrected. One activity associated to corrective maintenance includes resolving deadlocks, which occurs when two or more tasks permanently block each other. Adaptive maintenance includes enhancing system and database performance via based on utility assessments and optimized queries to improve performance. (Coronel, Morris, & Rob., 2013).

It is generally accepted that information is a vital commodity for the successful operation of today’s organizations. Nowadays modern business organizations are using computerized information systems in order to obtain such information. However as the technology advances rapidly the main issue is how can an organization should effectively use such an information system - which its management sometimes can be unpredictable - in order to effectively help the whole organization structure to improve and take the most out of it.

“A database is a structured collection of records or data that is stored in a computer system. In order for a database to be truly functional, it must not only store large amounts of record, but also be able to access those records fast and efficiently. In addition, new information and changes should also be easy to input.” (tech-faq.com) To be useful over a long term the database should be able to store all the records necessary for the business to function as well as be able to get all of this information back in case of a system failure or a crash. If all the information is loss a business could go bankrupt so the database is a fail

SQL injection or SQLi is a common technique used to hack into a website. Using this below code can help you prevent or stop the hacking. Shown below is a sequence of code snippets, which relate to preventing SQL injection with its use. It is a common technique that hacks into the site to see the contents of it, use of the code snippet is necessary when you are in the beginning process avoiding the hack.

-if appropriate storage is not there our whole database will crash due to less storage because
