...Windows Authentication on Microsoft SQL Server Introduction Microsoft SQL Server offers two types of security authentication: SQL Server authentication and Windows authentication. SQL Server authentication authenticates the user to the database using a database user name and password. Windows authentication is also referred to as "Windows Integrated Security" or a "trusted connection" because it relies on the user being authenticated, or “trusted,” by the operating system. Windows authentication is the authentication mode recommended by Microsoft. Windows authentication takes advantage of Windows user security and account mechanisms. By allowing Microsoft SQL Server to share the user name and password used for Windows, users with a valid Windows account can log into Microsoft SQL Server without supplying a user name and password. In addition to a single login within a Windows domain, Windows authentication provides a more secure mechanism for logging into Microsoft SQL Server. Standard Windows security mechanisms also provide the added advantages of auditing, password aging, minimum password length, and account lockout after multiple invalid login requests. The DataDirect Connect® for JDBC® SQL Server driver is the only JDBC driver for Microsoft SQL Server that provides two methods for supporting Windows authentication, a Pure Java (Type 4) implementation and a Windows-specific (Type 2) implementation. The Windows-specific implementation requires minimal configuration to enable...

...A Secure Intrusion detection system against DDOS attack in Wireless Mobile Ad-hoc Network Abstract: Wireless Mobile ad-hoc network (MANET) is an emerging technology and have great strength to be applied in critical situations like battlefields and commercial applications such as building, traffic surveillance, MANET is infrastructure less, with no any centralized controller exist and also each node contain routing capability, Each device in a MANET is independently free to move in any direction, and will therefore change its connections to other devices frequently. So one of the major challenges wireless mobile ad-hoc networks face today is security, because no central controller exists. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a link layer ad hoc network. Ad hoc also contains wireless sensor network so the problems is facing b y sensor network is also faced by MANET. While developing the sensor nodes in unattended environment increases the chances of various attacks. There are many security attacks in MANET and DDoS (Distributed denial of service) is one of them. Our main aim is seeing the effect of DDoS in routing load, packet drop rate, end to end delay, i.e. Maximizing due to attack on network. And with these parameters and many more also we build secure IDS to...

...Secured Authenticated Framework for Mobile Clouding VARRI MURALI KRISHNA(213CS1143) DEPARTMENT OF COMPUTER SCIENCE 1. Abstract Cloud computing is creates many challenges in the information technology world every day. In present situations use of resources using mobile phones becomes one of the essential things for everybody. The demands of the user in internet increasing day by day. But every wireless hand held devices don't have that much of resource availability and required facility. So, cloud computing is a better solution to give support resource consuming applications. If the mobiles are integrated with the cloud then user can get more facilities with resources required and big storage space for storing his private data. With addition to the benefits of cloud, there is a chance to face the security and privacy issues of the user data. This paper discuss important concepts of cloud computing and general security issues happened in mobile side as well as cloud and also describes basic idea of Kerberos. The aim of this paper is to propose the strong authenticated framework when mobiles are connected to cloud. We have proposed the improvement in the mobile cloud based framework for better security and privacy. Keywords: mobile cloud computing applications, security of data, Kerberos 2. Introduction and literature survey Rapid development in the mobile devices and cloud computing has creating some attention to everyone in the IT industry. Consider the development of security...

In the online world two vital factors are social networking and Virtual learning environment. Below those are described. Social Networking Hewson, et al., [1] asserts that social networking may be considered as an internet based social platform which allows people to make connection and communication with each other and to share their views and contents. In the present world social networking is very crucial to keep pace with the fast moving world. Social networking help to sustain contacts and networks overcoming the issues regarding time and distance. To function social networking a social networking site is required. There are so many sites are available but of them Facebook, Twitter, MySapce, Google Plus etc. are very popular. Particularly, Facebook is one of the most famous social networking which started its journey in 2004 and till third quarter of 2014 Facebook found more than 1.35 billion users. Facebook was establish in February, 2004 by Mark Zuckerberg along with Eduardo Saverin, Andrew McCollum, Dustin Moskovitz and Chris Hughes. Mark Zuckerberg is also the CEO of Facebook.

...DNS in Small Networks Step-by-Step Guide Microsoft Corporation Published: January 2008 Author: Jim Groves Editor: Jim Becker Abstract This guide helps you implement Domain Name System (DNS) on the Windows Server® 2008 operating system in a small network. Windows Server 2008 uses DNS to translate computer names to network addresses. An Active Directory® domain controller can act as a DNS server that registers the names and addresses of computers in the domain and then provides the network address of a member computer when the domain controller receives a query with the name of the computer. This guide explains how to set up DNS on a simple network that consists of a single domain. Contents Step-by-Step Guide for DNS in Small Networks 5 Planning DNS 6 Understanding the DNS namespace 6 Designing a DNS namespace 8 Creating an Internet DNS domain name 9 Creating internal DNS domain names 9 Creating DNS computer names 9 Installing and Configuring AD DS and DNS 11 Configuring Client Settings 19 Advanced DNS Configuration 27 Adding resource records 28 Automatically removing outdated resource records 29 Troubleshooting DNS 31 Step-by-Step Guide for DNS in Small Networks Domain Name System (DNS) is a system for naming computers and network services that maps those names to network addresses and organizes them into a hierarchy of domains.
