Today, in the world of communication, connected systems is growing at a rapid pace. To accommodate this growth the need for computational power and storage is also increasing at a similar rate. Companies are investing a large amount of resources in buying, maintaining and ensuring availability of the system to their customers. To mitigate these issues, cloud computing is playing a major role [1]. The underlying concept of cloud computing dates back to the ‘50s but the term entering into widespread usage can be traced to 2006 when Amazon.com announced the Elastic Compute Cloud. In this paper, we will discuss about cloud security approaches. We have used the term “CloudDrain” to define data leakage in case of security compromise.

Denial-of-service (DoS) attack: is an action that prevents or impairs the authorized use of networks, systems or applications by exhausting resources such as central processing units (CPU), memory, bandwidth and disk space. OR • Denial-of-service (DoS) attack: An attack that attempts to overwhelm a computer’s ability to handle incoming communications, prohibiting legitimate users from accessing those systems. Distributed DoS (DDoS) attack: A form of DoS attack in which a coordinated stream of requests is launched against a target from many locations simultaneously using bots or zombies. • Bot (also referred as botnet or zombie): an abbreviation of robot, which is an automated software program that executes certain commands when it receives a specific input. Not Defendable Attacks • DDoS attacks are difficult to defend against, and currently there are no controls that any single organization can apply! WHY? • Any system connected to the Internet and providing TCP-based network services (such as a Web server, FTP server, mail server, routers) is vulnerable to DoS/DDoS attacks.

With significant breaches of personal and corporate data being announced regularly, there is even more value in understanding how the dynamic attack chain really works in addition to what tools your organization can use to disrupt it. From break-in to ex-filtration, you will be taken through a "real-world" scenario to understand how easy it is for attackers to infiltrate your network and steal sensitive data. We will review the technologies you can use to combat these threats and contain the impact of a breach as well as determine what protection strategy you should adopt to avoid being the next headline. Join this live webinar, presented by Christopher Beier, IBM Security Senior Product Marketing Manager, to: - Experience a "real world" step-by-step scenario from break-in to ex-filtration - Learn in detail how the dynamic attack chain works - Understand which network and endpoint protections your organization should have in place View the on-demand recording: http://securityintelligence.com/events/nuts-bolts-dynamic-attack-chain/

The emergence of cloud computing has changed perception of all regarding software delivery, development models and infrastructure. Cloud computing has a potential of providing elastic, easily manageable, powerful and cost-effective solutions. The rapid transition to cloud computing has fueled concerns on the security issues. The migration of the user’s data and applications in a shared environment of a cloud, where there is a collocation of several users increases security related concerns. Several research efforts have been made in evaluating challenges related to security faced by the cloud computing environments, a number of solutions of such problems have also been proposed. Integrated security solutions should be devised to deal with the increasing security risks. In this paper, a detailed cloud computing survey, key services and concepts are being presented. This paper attempts to evaluate various security threats to cloud computing and a number of security solutions have also been discussed. Furthermore, a brief view of the cloud security regulatory bodies and compliance have also been presented. Despite the research efforts in cloud security field, there are still some open research problems and challenges which are discussed in this paper.

The availability of innovative DDoS attack tools and techniques has lowered the barrier of entry, which means an increase in the number of attackers launching DDoS attacks. Attack targets have also diversified. It used to be that finance, gaming, and e-commerce verticals were likely targets. Today, any organization, for any real or perceived offense or affiliation, can become a target of a DDoS attack. This while APT group and crimeware activity continues to grow, as actors in this space develop and unleash increasingly sophisticated attacks worldwide. Learn about: •Understand what is happening on the DDoS Landscape – the largest attacks and what is driving them •How Nation-State activity is going ‘internet-scale’ •Botnets, crimeware, intrusions – how these facets of the threat landscape tie in together

Assignment4 Assignment 4: Hashtables In this assignment we will use a rhyming dictionary and loading it into a hashtable and using the hashtable ADT(abstract data type) to implement a bad poetry generator. Objectives TODO #1: Implement a hashtable TODO #2: Loading the dictionary Optional: TODO #3: Removing unrhymable words Testing Testing can be done through Maven with the command, mvn test To run more specific tests, run the command mvn -Dtest=AssignmentTest#TESTCASEHERE test where TESTCASEHERE is the test case you want to run. These test cases can be found in src/test/java/AssignmentTest Ex: mvn -Dtest=AssignmentTest#test_2_puts test The results can be found in the command line or in target/surefire-reports/AssignmentTest.txt after execution. Part of grading will be these test cases. Alternatively, You can use the main method found in RhymingDict.java. In fact, the test cases are dervied from that main method. To Do 1: Implementing a Hashtable Youll be implementing a hashtable class called MyHashtable. It implements the interface DictionaryInterface. The hashtable youll be making will use Strings as the keys and Object as the values. Similar to linked lists, by storing Object as values, you can store any kind of object in the hashtable. To implement a hashtable: Use a protected inner class inside MyHashtable called Entry. This inner class stores Key/Value pairs. So it has two fields: String key Object value It also should have a constructor for initializing the key and value. Your hashtable will define three protected fields (remember that protected means that the field can only be accessed from within the class or by any child class of the class). int tableSize - the size of the array being used by the hashtable int size- the number of key/value entries stored in the hashtable MyLinkedList[] table - an array of MyLinkedList. The reason that each element of the array is a linked list is to store multiple entries which collide, that is, for which the hash for the different keys is the same index in the table. Youll be implementing the following methods on MyHashtable public boolean isEmpty() Returns true if the hashtable is empty, false otherwise. You can use the size field to determine this easily. public int size() Returns the size (number of key/value pairs stored in the hashtable). Theres more info about how to implement this method below. public Object put(String key, Object value) Adds a new key/value pair to the hashtable. If the key has been previously added, it replaces the value stored with this key with the new value, and returns the old value. Otherwise it returns null. public Object get(String key) Returns the value stored with the key. If the key has not previously been stored in the hashtable, returns null. Theres more info about how to implement this method below. public void remove(String key) Removes the key/value pair associated with the key from the hashtable. Theres more info about how to implement this method below. pub.

Assignment Overview Over two-thirds of Americans are considered overweight or obese based on BMI measurements. The prevalence of obesity and diabetes has significantly increased over the past forty to fifty years, resulting in a population sick with preventable diseases and increased medical costs. In 2012, HBO released a documentary series examining the obesity crisis in the U.S. that looks at the health risks of being overweight, weightloss ideas, childhood obesity and efforts to improve the public health. For this assignment, you will learn about the U.S.'s current obesity crisis by watching one of the episodes from the mini-series and answering five reflection questions upon finishing the episode. STEP 1: Watch the first episode of HBO's Weight of the Nation mini-series entitied, STEP 2: As a Word document, answer the five questions below and submit into the D2L drop box. 1. How does the knowledge of obesity's strong connection to several leading causes of death change your perception of obesity as a public health issue? 2. Discuss the theory of nature vs nurture in relation to obesity as depicted by this documentary. 3. Before watching this episode, what were your assumptions about the factors that have contributed to obesity? Did the film change your views? 4. Hearing the very personal stories of people who are suffering as a result of conditions related to obesity, are you more or less sympathetic and why? 5. If you were awarded money for your community, how would you spend it to help lower obesity rates?.
