? Database Security Shakeel [Pick the Introduction As more and more increase in information day by day which results in increase in data, this data is stored on more and more database systems which are usually distributed. Big and medium businesses are susceptible to security breaches from outside which might compromise their competitive advantage. For the security breaches within data transfer, different encryption techniques are employed for the safe data travel but the data connecting to database servers must be subjected to policies and mechanisms to protect it from vulnerabilities. A broad spectrum of information security controls is employed on the database servers to protect it from vulnerabilities to its confidentiality, reliability and integrity. These security controls may be technical, administrative, logical or physical. The vulnerability to the database security include unauthorized access by hackers or outside attacks or misuse by authorized personnel which are database users, administrators or system managers. A malware infection may cause unauthorized access to the database and may compromise its integrity and confidentiality via leakage of details deletion or permanent damage. This may also include denial of access to authorized users or a denial of service attack. Overloads or inefficient performance constraint may compromise database integrity and the data might be susceptible to damage physically (earthquakes, fire, flood) and should be provided with adequate physical protection or have proper backup. Design flaws and invalid data entry can also compromise the integrity and reliability of the database servers. Database Reliability Reliability of a database means that the database provides services for a significantly long period of time without any fail. It is because database may include data from different sources and a reliable access should be prudent for the database users. Key business data and process information is usually stored in databases and it is very important of DBMS users to have the data protected so that the data accessed is reliable. For this several security measures can be made in order to prevent databases from losing important data through damage or loss (Basta & Zgola. 2011). Database Integrity Database integrity refers to the consistency and the accuracy of data within the database and data warehouse systems. Data integrity is often times dubbed as data quality and data with integrity and a whole structure. There are various types of data integrity that is associated with databases. Physical integrity of a database refers to the immunity of a database system to physical damages such as power failures, earthquakes, floods etc. and that the database can easily be reconstructed in case of such catastrophe. Logical integrity of a database is equally vital as its physical counterpart and it entails that a database structure must be preserved and it is evident by the logical integrity of the structure when changes to one field do not put a cascading effect on other fields of the database. For example, the data in each element must be accurate, the data is auditable, there is access control for unauthorized personnel, users are correctly identified and the database must be available for the authorized personnel. Auditability of a databases addresses with the monitoring of who or what accesses the data base or has modified the database itself. Other data base integrity constraints include referential integrity and domain integrity. To ensure data integrity, data values are first standardized using specific data models or types. For this it is important that the data is complete in its business relations, functions, rules and dates and it is protected. Data integrity can also be implemented through other ways than database security where different error checking and validations must be checked in order to provide accuracy of data. For example, a numerical value in the in a date of hiring cannot be one that is ahead of the system date. In its realization, data integrity is actually a realization of the data being unaltered from its creation to its access and the data objects within the database are in themselves valid. Data integrity is maintained through database security when the data is not tampered with and an audit of data integrity gives a positive result of its reliability towards database users. Data in a database is transferred, updated and created in remote servers and it is important that it is also encrypted to maintain its confidentiality and integrity. Database must not be corrupted or subject to unauthorized disclosure and modifications so that critical business processes are carried out without fail. Many practices are employed by database security professionals in order to ensure integrity and the practices are data encryption, data backup, access control, and input and data validation (Mullins, 2013). In light of all this information it is easy to say that the key business processes revolve around the correctness and accuracy of data which can only be provided through database integrity insurance and protection. Thus Database integrity is important in maintaining trustworthiness in the data resources. Systems and Software Implementing Database Security For reliable database access many service-oriented architecture and other antivirus programs offer database security for reliable access of data and so that the integrity of data is not compromised. For example, McAfee’s database security solution offers real time database protection for the reliable access of databases and protecting its integrity. This software protects from internal, external and intra-database threats while there is no architectural reforms or expensive hardware is required. McAfee vulnerability manager exact location of vulnerability within the database system and more than 4,700 vulnerability checks are available for a detailed risk assessment of the whole database system and also provide fixed script for prioritized levels of threats (Mcafee, n.d.). Database activity monitor checks external and internal threats to the database integrity and reliability and the sensors within the software automatically detect any and all unauthorized access or activity within the database system and terminate any such malicious behavior without affecting the overall performance of the database system and its access reliability. SOA systems now considers data provenance and addresses security reliability and integrity of routed data in the system. For this the origins and routes of the data need to be protected in order to ensure data integrity, security and reliability (Bertino & Sandhu, 2005) References Basta, A., & Zgola, M. (2011). Database security. Boston, Mass: Course Technology. Bertino, E. and Sandhu, R. (2005). Database security - concepts, approaches, and challenges.
