2. What are the DBA’s responsibilities regarding access privileges? 19. You are employed as a DBA for a medical practice. You have implemented multiple safeguards to protect patient privacy and conform to HIPAA regulations. What other practical, common-sense measures should you take to ensure that the database system is secure? Identify at least three measures and explain the purpose of each one. 20. For credit card processing, stock exchanges, and airline reservations, data availability must be continuous. There are many other examples of mission-critical applications. Research the Internet to find four additional mission-critical applications and explain why data availability must be continuous for these applications. Be sure to cite your references. Solution 2) Responsibilities of DBA when considering access privileges: Basically Database administrative ministrator is the master of database and has to make sure that anyone who is using the database only have necessary access and not every which might mess up the data. Also confidentiality,criticality are some factors while granting access of information. 19) We can have following measures is place: a) Avoid using shared server as its put risk of keeping your senstive information in some one else\'s hand. b) Make sure security controls are enabled on your database c) If possible keep Database server and your web server seperate because keeping them both on same gives chances to get administrator account break and access to all information. 20) Some of mission critical application could be : a) Traffic Control : The data is traffic control needs to be up to date to every nano seconds other wise the automatic working signals might end up in mess and damage life..

The rise of cloud computing has been driven by the benefits, the cheapest purveyor of application hosting, storage, infrastructure, huge cost savings with low initial investment, elasticity and scalability, ease of adoption, operational efficiency, on-demand resources. With all the security and Privacy Laws in the Health Care field today anyone that works with confidential information should know how to protect that information. The Health Insurance Portability and Accountability Act (HIPAA) privacy and security regulations are two crucial provisions in the protection of healthcare data. Governance, compliance and auditing are becoming as important pedagogical subjects as long established financial auditing and financial control. Designing sound IT governance, compliance, and auditing is a challenging task. This Thesis elaborates the concept of HIPAA compliance in cloud computing by taking a look at the history and dynamics and how Cloud computing changes the astir of certain parts of HIPAA Security requirements. We briefly describe the cyber warfare as a premise to enforce the reasons for complying with government regulations for information systems. The purpose of this Thesis is to explain the importance of HIPAA and research what it takes for Healthcare data to be HIPAA Compliant. Also, explaining what is expected of Healthcare industries if there is an audit and how does HIPAA Auditing play a big part in HIPAA compliance. The Cloud is a platform where all users not only store their data but also used the services and software provided by Cloud Service Provider (CSP). As we know the service provided by the cloud is very economical due to which the user pay only for what he used. This is a platform where data owner remotely store their data in the cloud to enjoy the high quality services and applications. The user can access the data, store the data and use the data. In a Corporate world there are large number of client who accessing their data and modifying a data. To manage this data we use third party auditor (TPA), that will check the reliability of data but it increases the data integrity risk of data owner. Since TPA not only read the data but also he can modify the data, therefore a novel approach should be provided who solved this problem. We first examine the problem and new potential security scheme used to solve this problem. Our algorithm encrypt the content of file at user level which ensure the data owner and client that there data are intact.

To understand de Broglie waves and the calculation of wave properties. In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength- momentum relation as that obeyed by light: Lambda = h/p, where Lambda is the wavelength, p the momentum, and h Planck\'s constant. Consider a beam of electrons in a vacuum, passing through a very narrow slit of width 2.00 mu m. The electrons then head toward an array of detectors a distance 1.013 m away. These detectors indicate a diffraction pattern, with a broad maximum of electron intensity (i.e., the number of electrons received in a certain area over a certain period of time) with minima of electron intensity on either side, spaced 0.519 cm from the center of the pattern. What is the wavelength Lambda of one of the electrons in this beam? Recall that the location of the first intensity minima in a single slit diffraction pattern for light is y = Llambda/a, where L is the distance to the screen (detector) and a is the width of the slit. The derivation of this formula was based entirely upon the wave nature of light, so by de Broglie\'s hypothesis it will also apply to the case of electron waves. Express your answer in meters to three significant figures. Solution lambda = h / p xmin = L lambda / a lambda = a * xmin / L = (2 * 10-6 * 0.519 * 10-2) / 1.013 = 1.02 * 10-8 m.

Item 8 Singly ionized (one electron removed) atoms are accelerated and then passed through a velocity selector consisting of perpendicular electric and magnetic fields. The electric field is 158 V/m and the magnetic field is 3.13 Times 10^2 T. The ions next enter a uniform magnetic field of magnitude 1.73 Times 10^-2 T that is oriented perpendicular to their velocity. How fast are the ions moving when they emerge from the velocity selector? If the radius of the path of the ions in the second magnetic field is 17.4 cm, what is their mass? Solution A) In Velocity selector Electric field & Magnetic field forces on ions are equal & opposite ,this is because it allows ions with a particular velocity only passes undeflected. so we can say, Bqv = Eq B:magnetic field density E:Electric field v:velocity at which the ions remains undeflected. v=E/B v = 158V/m / 3.13*10-2 T => v = 4.78*103 m/s B) as it enteres next in uniform magnetic field of value B=1.73*10-2 T Work done in uniform magnetic field is zero.It only changes the direction.So B provides centripetal force for the ions while changing direction in circular path of radius r=17.4cm. Bqv = mv²/r m = Bqr / v = (1.73*10-2T)(1.6*10-19C)(0.174m) / (4.78*103m/s) =>m = 1*10-25 kg.
