Q. Write about CAS Architecture?
Ans. CAS means contenet addressed storage. Different kinds of data have different lifespan, some data has to ve conserved and some data has to be deleted or vanished in a shorter span of time. Generally as the age of the data increases, the chances that the data will be modified or updated becomes considerably very less. It will be just accessed by various appications rather being modified. Such a kind of dtat is known as fixed content. The rate at which data is being produced is so high, that, it has become very difficult to 'fixed content' like data and make it available 24*7 as per the user demand. Such a kind of complexity in managemnet of data advented the development of CAS.
Content addressed storage is an objetc based method was purposely built for storing 'fixed content' like data. It is mainly constructed for securely storing the data online and retriving of the same. The main differenence in cas and other methods is that cas stores the data of the user and its attributes as seperate objects. The object stored is assigned a unique add. known as CA(content address). Almost all the organizations which have some data which has to be retained for a very large period of time, such as legal documents, some photographs, financial statements of previous years. These kind of data may be needed for analysing the perfomance, while making future plans. This arises frequent demand of the data, with fast retrival method. There for these data is placed at archive. Archive is a repository where fixed content is placed.

■■ Report generation and event notification: Provides on-demand reporting and event notification. A command-line interface (CLI) or a graphical user interface (GUI) can produce various types of reports. Any event notification can be communicated to the administrator through syslog,
SNMP, SMTP, or e‑mail.
■■ Fault tolerance: Ensures data availability if a component of the CAS system fails, through the use of redundant components and data protection schemes. If remote replication of CAS is implemented, failover to the remote
CAS system occurs when the primary CAS system is unavailable.
■■Audit trails: Enable documentation of management activity and any access and disposition of data. Audit trails are mandated by compliance
requirements.
The re-engineered FCIC network has become today's CJ Net. It differs from the FCIC network in two fundamental ways. First, agencies connected through the CJ net operate in a peer-to-peer relationship. Every agency "sees" every other agency on the network and has the capability to access information that agencies wish to share with each other. There is no "master" or host computer controlling communications between agencies. Each agency determines the types of information they wish to share. Second, a broader range of criminal justice agencies is being brought into the network. The CJ Net project is focused on connecting Clerks of the Court and state and local courts throughout the State. Other criminal justice agencies will be added as funding allows. (FDLE-CJ Net, 1998)
CACREP is the Council for Accreditation of Counseling and Related Educational Programs. CACREP focuses on accrediting counseling programs, such as Clinical Mental Health Counseling and School Counseling, in the master-level and doctoral level programs.

Every piece of information must be traceable back to the data input that produced it. The main action of audit trail is captures a sources of all data items at the time of getting entrance into the system. The other constituent of input control and security involves data security rules and measures to protect data from being or lost or damaged. The records retention policy is the practice of storing documents in a safe location and making sure to see to legal requirements or business needs. Input security and control also involves the process of encrypting or encryption of data so only users with the code it software can read
According to the CDC, FAS is the leading cause of preventable developmental disabilities and birth defects. It is not known how many people have fetal alcohol spectrum disorders or FASD of which fetal alcohol syndrome is the most prevalent of the spectrum of disorders. CDC studies have identified 0.2 to 1.5 infants are born with FAS per 1000 live births, (this rate is comparable or higher than rates for other disorders such as Spina Bifida and Down syndrome) another study found FAS in 0.3 out of 1000 children aged 7 to 9 years. The Minnesota Department of Health states that because not all children exhibit facial characteristics, it is under diagnosed and up to 20% of children have been exposed prenatally to alcohol.

In modern day business, there can be so many pressures that can cause managers to commit fraud, even though it often starts as just a little bit at first, but will spiral out of control with time. In the case of WorldCom, there were several pressures that led executives and managers to “cook the books.” Much of WorldCom’s initial growth and success was due to acquisitions. Over time, WorldCom discovered that there were no more opportunities for growth through acquisitions when the U.S. Department of Justice disallowed the acquisition of Sprint.

For an in-depth defence approach, case study provides a series of things that describe about what is working nowadays for a secure data.
Akamai Technologies, Inc. is an organization which delivers the content over the Internet. It is one of the largest organizations which provide the distributive Computing Platforms; it provides a cloud based services to the end user. It serves 30% of the overall web traffic. Akamai provided numbers of servers which are located all over the globe and stores the web application of the clients. It provides a faster access to those applications because of the distributive contents in to various servers around the world. Akamai does not want the long routes to it distributed the data based on the locations, it works as like a work or a task which is not possible to be completed by a single persons is divided in to multiple process or threats or assign to teams to complete their individual part, so that task can be complete faster, in the same way the contents are stored at different servers based on their access mechanism.
More firms and industries are adopting cloud computing because of its flexibility as well as convenience. The health care industry on the other hand has been very slow when it comes to the adoption of this new trend. However, gradually many hospitals as well as clinics have been able to recognize the benefits of cloud computing and most of them have embraced this new technology to revolutionize their procedures. In the 21st century, it is extremely hard and challenging for physicians to keep track of all the data that exists from the patient records to insurance information. The traditional system is often a burden as one has to transfer physical files from one facility to another. This process is tiresome and cumbersome; it also wastes time and money that could have otherwise been put into other productive uses (Spagnoletti 12). The cloud storage systems often allow organizations to place data on each and every centralized electronic system that can be accessed anytime from anywhere and anytime. The healthcare industry often has to deal with large amounts of data, and the cloud services often help them to manage as well as access health records effectively in order to provide patient care in an effective and efficient manner.
Cisco Systems, Inc. is a leader in networking for the internet, they develop hardware, software, and services to help create internet solutions that make internet networks possible.
