Database Security:
Database security is a critical Domain of Computer and Information Security that deals with protection of an individual database or group of database from illegal access, injections or possible destruction. Data can be a customer's information, intellectual property, financial asset or any number of other records that can be maintained and managed on a system. Without Database security people are at risk of identity fraud, theft, destruction of property and much worse. The global costs of such security breaches runs from over a billions of dollars yearly, and the cost to individual companies can be extreme, sometimes disastrous.
One of the most popular method for protection of database includes storing a backup in a secondary location or datacenter. The Advantage of storing backup in secondary location is the process of restoration and damage prevention in case of data destruction or disaster at Primary source .
A firm’s database infrastructure often contains the most important data and are subjected to a wide range of attacks. Some of the threats to database security are excessive and unused privileges, SQL Injection, DoS etc.
Excessive and Unused privileges is when someone in the firm is granted database privileges that exceeds the requirement of their job function, these privileges may sometime be abused. A good example for Excess and Unused Privilege can be a University System Administrator who’s primary function is to maintain student information, but due to excessive privileges could potentially have access to modification of Student’s grades. Another example could be of an employee with access to human resources database access, leaving the organization i...

The use of portable devices are causing most of the organizations to deal with higher risk from hackers gaining access to sensitive data. Database are mainly targeted by attackers since it contains high volume of important and potentially critical data. The best way to overcome these risk are through storing important information as backups and securing data transmission over public network. Organization should set up firewalls between company’s intranet and internet in order to block any external device access into the network . With all being said organization should continuously educate their employees about the risks and keep a track and secure the portable devices used by IT personnel. If such security measures are implemented by an organization they can ensure that critical and important information could be less susceptible to vulnerabilities.
Security of the companies data is one of the most important components which allows the business to perform its day to day operation using various networking devices, services that absolutely needs to be protected from intruders. Some of these devices include online transactions, the exchange of data between users and clients both internal and external and external web data needs to be secured. There are several polices that would need to be configured such as a web sever and firewall configurations. However, with these configurations the first and most important task is to identify any vulnerabilities or loopholes in security within the company. The company has both LAN (Local Area Network) and WAN (Wireless Local Area Network) and a web sever. These resources need to be secured at all times from hackers or anyone else by implementing the appropriate security measures.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
There is constant concern about different kinds of devices and tools because of their vulnerability: laptops; personal computers in the home; libraries and public workstations; USB Flash Drives and email, to name a few. These items are easily accessible for those attempting to breach security.... ... middle of paper ... ...
Often technology provides some of the most cost effective and fastest communication through various networks like the internet such that one can easily interact without any difficulties. In today’s world, information technology is considered as an entity, this is because more and more systems have become interdependent to the internet, so without it these systems will fail to continue with their normal operations (Riedman,2017) . Information technology is a sector that needs to be properly secured from various security threats such as cyber-attacks, espionage, spyware, physical theft cases or malicious attacks from viruses such issues may occur and lead to loss of data, physical damage of hardware or unauthorized access to private and confidential documents. I would recommend installation of backups for the systems to avoid disruptions, duplicates should also be made and stored in a quite different system from the original document. The owners should also ensure the systems are secured to avoid unauthorized access and to prevent environmental
But if they lose they data and work they have to make sure that they can get their data back this is why they use backups one hard drive but if that is lose or destroyed they won’t be able to get it back and that is why the now use cloud as well this makes it so that their data is save and is heavily encrypted so that no one can get
It allows the backup server to hold the latest data almost at all times. Data can also be stored to removable media and devices, which are also taken periodically to minimize outdated data. However, simply having a location for data is not a complete plan, it requires much
Hackers who are able to get into the network must be detected quickly, otherwise there is a risk that they will be able to steal keys necessary to decrypt the system and steal important data. All portable devices, servers, and other media where data may be stored should be encrypted. The expansion of encryption could help keep sensitive information protected, even if the information has been stolen. Furthermore, it is important to note, encryption should not be used as the only defense mechanism against a cyber attack.

Inconsistently storing organization data creates a lot of issues, a poor database design can cause security, integrity and normalization related issues. Majority of these issues are due to redundancy and weak data integrity and irregular storage, it is an ongoing challenge for every organization and it is important for organization and DBA to build logical, conceptual and efficient design for database. In today’s complex database systems Normalization, Data Integrity and security plays a key role. Normalization as design approach helps to minimize data redundancy and optimizes data structure by systematically and properly placing data in to appropriate groupings, a successful normalize designed follows “First Normalization Flow”, “Second Normalization Flow” and “Third Normalization flow”. Data integrity helps to increase accuracy and consistency of data over its entire life cycle, it also help keep track of database objects and ensure that each object is created, formatted and maintained properly. It is critical aspect of database design which involves “Database Structure Integrity” and “Semantic data Integrity”. Database Security is another high priority and critical issue for every organization, data breaches continue to dominate business and IT, building a secure system is as much important like Normalization and Data Integrity. Secure system helps to protect data from unauthorized users, data masking and data encryption are preferred technology used by DBA to protect data.
But, if the intruder gets the algorithm of the sentinel application on data, then the data can be breached easily. Hence, it appeared ineffective in due course of time. Thus a need of specific system rose to have such process which can monitor the cloud without adding any sentinels. Hence, demand of more improvised Auditor emerged which can provide effective integrity assurance for database services. Due to absence of such Auditor, have led to many inevitable situations, for example, recently a big robbery of data had occurred in the South Korea of three major banks. It had shown major drawbacks in the security and storage mechanism of IT infrastructure. The data which was robbed contained information like monthly card usage, card numbers, salaries etc, which had led to a lot of tension among the account holders. The card holders were running towards the bank for cancelling the card, so that no money from their account could be transferred. This episode pro-vided a lesson to keep the storage servers watertight, protected and detect prohibited action of culprits. In IT industry, large improvements in authentication system, firewalls and data access has to be made to avoid such incident in future. The presented work checks the integrity of data, so that no part of data could be modified, deleted and inserted without user permission. This paper provides users, the freedom of examining the integrity which observes indifferently toward both Cloud service providers (CSP) as well Data Owners. Monitoring of data needs requires profound study of database storage as well as methods of data transfer and access which is a very complex job. The methods must be reliable and must be transparent so that questions will not arise on the way of work...
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
Privacy exist wherever personal information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. The challenge of data privacy is to use data while safe-guarding individual's privacy preferences and their personally identifiable information. The fields of computer security, data security, and information security design and utilize software, hardware, and human resources to address this issue.
Security is very important for many different reasons. A nation must insure their safety as a whole, as well as the persons living in the nation. It is equally important that the nation's economy is stable and growing. Security is something that every nation deals with, in many different ways. It is a way that nations come to together and create allies. However, it is also a way for nations to create enemies. There are a variety of concerns that require attention around the world including state security, human security, and economic security. Political and economic relations impact each of these security issues different proven by history and present events around the world.
The DBMS function is it has recovery services. It means that if the database is damaged, the database management system will recover the records and all the information. The data and the records need to recover and backup so that it will not be permanently lost. The regular backup is needed because the user doesn’t know what will happen to computer and the data may be loss.
conference using a PowerPoint file. The database management system allows a company to run more efficient, smoothly, and be more productive. Database management systems also allow a business to be more secure. The database administrator can create the user permissions, which allows each employee access to different things. This is usually done by assigning different usernames and passwords. It can prevent employees from viewing certain documents that are meant only for cooperate, or preventing them from accidentally deleting
