Explain why data security is important.
The many aspects of data security are integral and critical with any businesses or home computer user. These areas include Client information, payment/transactional information, individual files, banking information and proprietary intellectual property. These forms of data and information are difficult to replace once lost. Though data security often refers to protection from unwanted hackers, spyware and viruses it, also, comes in the form of natural disasters with the likes of a flood or fire. The later forms of data loss are just as damaging as those from hackers, viruses, spyware, Trojan horse or a malware infection. To answer the question why data security is important is because the damages

What is deadlock and how can it occur?
Concerning database deadlock is a state that happens with two or more database sessions have data locked, and those database session call for a lock on the data that the, different, sessions have locked already. The deadlock occurs when the sessions are waiting for one another during this state no transactions can occur, and the sessions are stuck in a wait mode. This is known as deadlock. “Both queries then wait endlessly for each other to release what they each need to proceed. This is called “deadlock” or “the deadly embrace.” (Gillenson, 2015)

1.What is data administration?
Data administration is a form of data resource management that is an organizational task, it requires working in specific areas of information systems to create plans, diagrams, organize, designate and relate various controls over data resources. The various data resources are most often stored in databases and are part of a database management system or software like excel or access or an open source spreadsheet. In many organizations the data administration, which is operated by the database administrator, involves many duties such as what follows in this quote. “In order to reduce errors, improve performance, and enhance the ability of one is worker to understand the work done by another, it is important for the data administration function to set standards regarding data and its use. One example of standards is controlling the way that attribute names, table names, and other data-related names are formed. Attribute names must be meaningful and consistent” (Gillenson,
In a multi-process system, deadlock is an unwanted situation that arises in a shared resource environment, where a process indefinitely waits for a resource that is held by another process. A deadlock occurs when two or more tasks permanently block each other by each task having a lock on a resource which the other tasks are trying to lock. When a detection algorithm determines that a deadlock exists, the system must recover from the deadlock. The most common solution is to roll back one or more transactions to break the deadlock.
The Human and Ethical Aspects of Big Data, quickly outlines an array of ethical problems that big data has had and will continue to develop in the upcoming years in our society. The author begins by giving an example of the earliest use of big data, the census. Census data can provide a plethora of benefits to society, representation in government, civil planning, such as road and water treatment, as these take years to construct and having the population and these necessities, Time align is crucial. As the author, uses the example of the internment of Japanese-Americans in 1943. Here is big-data supposed to help the citizens of the Unites States, the big data that is supposed to be private. Now in 1943, big data being used to discriminate
Encryption is a key solution to mitigate potential corruption without fault. Many resolutions to problems are large enough to ensure that the whole company is in complete submission to the security regulations. Data encryption enables a company to reach a high level of security with ease and low cost. Data encryption can also shield confidential information stored on a computer
The data breach at Target had a massive impact on cyber security. According to Lauren Abdel-Razzaq, we live in a world where consumers don’t even think twice about paying with a credit or debit card or buying items online or with mobile devices (2014). However, data breaches have become a major threat and continue to impact companies all over the world. Companies should take information security as seriously as possible. We don’t live in a perfect world. Anything can happen at any time, even if a company has the most sophisticated security system in place. It is how a company reacts to a data breach that will make or break them.
A IT disaster can be unpredictable and inevitable to an organization. For instance, these types of disasters “can be man-made, natural disasters, technology failures and more” (Business continuity and disaster recovery plan, 2008). Many cybersecurity companies should emphasize the need for organizations to have a DR/BCP in place. In fact, cybersecurity “should acknowledge and embrace the linkages between information security and other departments, such as business continuity, disaster recovery, and emergency management” (Kirvan, P, 2014). It is important for a CISO in an organization to integrate cybersecurity to their DR/BCP. According to SISS-Consulting, “75% of organizations say IT risk can impact customer satisfaction” (Cyber Security, 2016). There are a variety of reasons, plans, and implementations that a CISO must have in mind when they are looking to
The purpose of this posting is to explain what privacy and confidentiality mean and then review the case study about the options of reporting abuse in a child and what principles of ethics are involved with it.
Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers must protect the customers’ personal information from hackers or competitors. They also have many business files or contracts that need to be strictly protected. Without data encryption, these important information may fall into wrong hands and be misused by others. Besides, data encryption may be used to secure sensitive information that exists on company networks, or create digital signatures, and help to authorize in business. No one should underestimate the importance of encryption. A little mistake in encryption may make sensitive information revealing, or even result in illegal and criminal accuse.
Max Thielen Last year Target fell victim to a massive cyber attack that compromised data on millions of its customers. The breach lasted from November 27 to December 15. During that time, information on 40 million debit and credit accounts was stolen. In addition, Target would later report that another 70 million customers’ names, phone numbers, and mailing addresses had been stolen (Whitney). A piece of malware that retails on the black market for around $2,000 is believed to be the culprit for the stolen data.
Data is very important and to keep it secure is more important, DBA has to make sure that database has enough security, they need to keep track of all database access activity and denied permission to unauthorized users. This also involves creation of new User roles, application role and maintenance of these roles.
Ques1 Provide a brief overview of the case study This case study is based on the European Union Agency for Network and Information Security (ENISA) to examine the current and emerging cyber threats and threat trends for emerging technology areas. This will be followed by the explanation of threats, threat agents, technology areas and attack methods. This case study also provides a description of the procedure followed and also a few descriptions on use cases of cyber threat intelligence. The primary commitment of the ETL 2014 lies in the recognizable proof of top cyber dangers inside the reporting time frame. With the developing risk landscape, it makes up the fundamental commitment towards identifying cyber dangers.
Our clients and other parties with whom we do business entrust the company with important information relating to their businesses. It is our policy that all information considered confidential will not be disclosed to external parties or to employees without a “need to know.” If an employee questions whether certain information is considered confidential, he/she should first check with his/her immediate supervisor.
Oracle's relational databases represent a new and exciting database technology and philosophy on campus. As the Oracle development projects continue to impact on University applications, more and more users will realize the power and capabilities of relational database technology.
Deadlock is very common and may occur during the processing of many items, it is most likely to happen when processors are waiting to see a specific type of exclusive resources. A very good example of this would be “Some computers, usually those intended for the time-sharing and/or real-time markets, are often equipped with a hardware lock, or hard lock, which guarantees exclusive access to processes, forcing serialization” Dead Lock, Introduction to Concurrency Control, 2006 .
Privacy and Security are very important aspects in regards to computer databases and keeping them safe. Data Privacy is a way to keep your information secure, and keeping your information secure means it’s going to be kept private (vice versa). Information and data privacy is the relationship between gathering and classifying data and technologies while at the same time keeping them private in the context of the organization. While Computer security and IT security are defined as the means of security and how they translate to computers, their network infrastructures, and the data encompassing the databases that store this data and making sure they are kept safe and classified.
Cryptography is the science of using mathematics to encrypt and decrypt data. Cryptography enables you to store sensitive information or transmit it across insecure networks so that it cannot be read by anyone except the intended recipient. While cryptography is the science of securing data, cryptanalysis is the science of analyzing and breaking secure communication. Classical cryptanalysis involves an interesting combination of analytical reasoning, application of mathematical tools, pattern finding, patience, determination, and luck. Cryptanalysts are also called attackers (The Basics of Cryptography)
