Aim: Distributed denial of service (DDoS) attack is a continuous critical threat to the Internet. Derived from the low layers, new application-layer-based DDoS attacks utilizing legitimate HTTP requests to overwhelm victim resources are more undetectable. The case may be more serious when such attacks mimic or occur during the flash crowd event of a popularWebsite. Focusing on the detection for such new DDoS attacks, a scheme based on document popularity is introduced. An Access Matrix...
DOS, which stands for Denial-Of-Service, seems to be a very serious concern these days. When it comes to DOS, an attacker tries to stop legitimate users from having access to services or information. The attacker may target anything from your computer, its network and whatever related to your computer so that you would not be able to have access to your email, online accounts (banking, etc), websites, or other similar services. Normally, DOS attack takes place when an attacker floods away any...

Wireless networking is a tantalizing technology for health care. With handheld devices and wireless technology, the practitioner can have ubiquitous access to patient information, clinical functions, business functions, and patients themselves. Wireless networks can bring information access, data collection capabilities, and clinical applications closer to the point of care than is possible using desktop computers and wired networks. User-friendly, hand-held devices and ubiquitous connectivity...

It allows organizations to place control of organization-wide database development in the hands of database administrators (DBAs) and other specialists. A DBMS is a system software package that helps the use of integrated collection of data records and files known as databases. It allows different user application programs to easily access the same database. DBMSs may use any of a variety of database models, such as the network model or relational model. Flat Files In database management, a...
The critical parts to a computer is everything that resides in the case, the motherboard, processor, Ram, Hard drive, and a power supply unit are the core fundamentals of a computer and general dictate how fast it will work. Other parts like graphics adaptors, sound cards, network adaptors are essential pieces if the computer is to be used for computer gaming. There are also several other input and out device that also help in the function of the computer, most importantly a VDU (visual display...
Introduction McWiLL is the most advanced broadband wireless solution provided by Beijing Xinwei Telecommunications Technology. The technology is based on SCDMA, and is known as Multicarrier Wireless information Local Loop (McWiLL). McWiLL combines SCDMA's traditional use in narrow-band voice and introduces a mobile broadband data service that ties into an IP-based core network. It is based on CS-OFDMA adaptive modulation, and uses dynamic channel allocation and smart antennas to enhance its...
ABSTRACT-: Commercial Off-The-Shelf (COTS) are pre-build components, developed by third party, available to the end user. COTS can either be hardware components or software applications. COTS applications include licensed, shareware and freeware software with commercial support. In recent times, use of COTS applications has increased largely due to their reduced cost and development time. In contrast to COTS applications, building customs software from scratch require a lot of time and...
In recent years, with the development of information technology, the operation of enterprises has gone through a drastic revolution. Data information flow became the lifeblood of enterprises. However, in such a situation, people would worry about disclosure of privacy and are likely to provide phony information rather than the authentic. So with the development of data analysis and processing technique, the privacy disclosure problem about individual or company is inevitably exposed when...
