Cloud computing in plain English

State of security readiness

State of security readiness

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. With this pay-as-you-go model of computing, cloud solutions are seen as having the potential to both dramatically reduce costs and increase the rapidity of development of applications.

Privacy challenges and solutions in the social web

Privacy challenges and solutions in the social web

Research related to online social networks has addressed a number of important problems related to the storage, retrieval, and management of social network data. However, privacy concerns stemming from the use of social networks, or the dissemination of social network data, have largely been ignored. And with more than 250 million active Facebook (http://facebook.com) users, nearly half of whom log in at least once per day [5], these concerns can't remain unaddressed for long.

Computer security and intrusion detection

Computer attacks are now commonplace. By connecting your computer to the Internet, you increase the risk of having someone break in, install malicious programs and tools on it, and possibly use it to attack other machines on the Internet by controlling it remotely.Several major banks have been subject to attacks, in which attackers gained access into customers' accounts and viewed detailed information about the activities on these accounts. In some instances the attackers stole credit card information to blackmail e-commerce companies by threatening to sell this information to unauthorized entities. Several online trading companies and e-commerce sites were shut down temporarily due to major packet flood attacks, also known as Denial-of-Service (DoS) attacks, causing these companies to lose revenue, customer satisfaction, and trust [10]. A major software development company discovered that attackers had broken into its network and stolen the source code for future releases of its popular products. Just recently, the source code of the future flagship product belonging to a major software development company was stolen and made publicly available on the Internet.In order to combat this growing trend of computer attacks, both academic and industry groups have been developing systems to monitor networks and systems and raise alarms of suspicious activities. These systems are called Intrusion Detection Systems (IDS).

Mutual authenticating protocol with key distribution in client/server environment

The explosive growth of networked and internetworked computer systems during the past decade has brought about a need for increased protection mechanisms. This paper discusses three authentication protocols that incorporate the use of methods that present effective user authentication. The first two protocols have been previously discussed in the literature; the third protocol draws from the first two and others to produce an authentication scheme that provides both mutual authentication and secure key distribution which is easy to use, is compatible with present operating systems, is transparent across systems, and provides password file protection.
