A mobile ad-hoc network is a self-configuring infrastructure less network of mobile devices connected by wireless. It is highly vulnerable to attacks due to the dynamic nature of its network infrastructure. Routing attacks have received considerable attention since it could cause damage to MANET. Existing solutions typically attempt to isolate malicious nodes. However which may result in the unexpected network partition, causing additional damages to the network infrastructure. Here a...
Geographic Information system (GIS) is a relatively new field and it has started in the 1970's. In Early days computerized GIS was only available to companies and universities that had expensive computer equipments. But technology has evolved surprisingly and these days, anyone with a personal computer or a laptop can use GIS software. GIS Applications have also become much more user friendly than it was in early days. GIS tools are normally programs with a graphical user interface since it is...
The name "Kerberos" comes from the mythological three-headed dog whose duty it was to guard the entrance to the underworld. The Kerberos security system, on the other hand, guards electronic transmissions that get sent across the Internet. It does this by scrambling the information -- encrypting it -- so that only the computer that's supposed to receive the information can decrypt it. In addition, it makes sure that your password itself never gets sent across the wire. kerberos has...
Stuxnet, a network worm that, during the early part of 2010, began to infect Industrial Control Systems (ICS) and programmable logic controllers (PLCs) becoming the first rootkit for PLCs. PLCs are usually not connected to the Internet, or the internal network, so the creators had to devise a method to get the worm onto these systems. The worm would use 4 zero-day vulnerabilities to propagate through internal networks, and would load itself onto flash drives. Once the flash drive was plugged...
1What are the benefits of configuring mail on database. Database Mail, a new addition to the SQL Server 2005 database engine, is as simple to use as it is useful. Destined to be the replacement for SQL Mail, Database Mail uses a Simple Mail Transfer Protocol (SMTP) server to send e-mails rather than using the MAPI accounts that SQL Mail required. This allows your organization to send e-mails with attachments, e-mail query results, attach query results, and format HTML e-mails. It also gives...
ABSTRACT Simulation is the imitation of the operation of a real world process or systems over time. The great advances in information storage and digital technology in computer software has greatly enhanced the engineer's ability to model designs. Simulation can be used to experiment with new designs or policies prior to implementation so as to prepare for any type of simulation. Shannan (1975) has defined simulation as the process of designing a model of a real system and conducting...
Apples claims about iPhone privacy and security are exaggerated, according to software engineer and security expert Nicolas Seriot, who gave a presentation yesterday about the iPhone at the Black Hat Conference in DC. Apples sandboxing technology restricts iPhone applications to operating system resources with a list of deny/allow rules at the kernel level, but these and other permissions are "way too loose," and "Apple should not claim that an application cannot access data from...
Windows Forensic analysis is the analysis which is related with the parts, methods etc of the windows. If we want to investigate the compromised windows hosts than, we need windows forensic analysis. My complete research is about the analysis of the windows The main aim is to research about the systems of windows like my whole research about windows includes the file systems of windows XP, windows XP file hiding places, information and the data analyze on the windows XP. Research about windows...
A good user interface design encourages an easy, natural, and attractive interaction between a user and a system, and it allows users to carry out their required tasks. It is a systematic approach to the understanding of people, their thoughts, emotions and behavior. The application of this understanding helps to solve human problems. By this paper we discuss how work psychology affect the human computer interaction and what are the problem occurs. We also discuss the relationship between...
Network architecture is the conceptual design that defines the structure and behavior of a network. It is a formal description of a network which defines the network components and provides a plan to implement the overall network. The network architecture requirements should be provide before the design of network architecture to determine the needs and conditions to meet with the network. Heterogeneous MANET architecture, HetMAN will be introduced in this chapter to indicate the placement for...
