Closer Look of User and Group Accounts in Windows 7

Windows 7 provides you with two types of user account:
1 Local user account
2 Domain user account

The users account can be easily added and removed with Control Panel's User Account options. You can access Local Users and Groups through Computer management.
Domain user account: Those users account that are defined in active Directory are called domain user accounts. Domain user account can be created using Active Directory Users and Computers. When you install the Remote Server Administrator Tools on your Windows 7 computer, this tool would be available to you on the administrative tool menu.

User name: the display text for the account
User Computer: The computer where user accounts exist.User name is displayed when describing account privileges and permissions still security identifiers (SIDs) are the key identifiers for accounts. SIDs is unequaled identifier that combines domain security ID prefix with a unique relative ID for the users. With these identifiers Windows 7 tracks accounts and users name. It also allows you to change users name and delete accounts without caring about that someone might re-create an account and gain access to it.
When a user name is changed by you, inform Windows 7 to map a particular SID to a new name and if you want to delete an account, simply inform Windows 7 that the specific SID is no longer valid. and even if you want to create an account with the same user account, the new account would not be given the same privileges and the permission as the new account you have created will have a new SID. Passwords are the valid proof for an account hence the users accounts can also be associated with passwords and certificates.
Default user accounts are installed with the installation of latest operating system Windows 7. It provides you with many built-in accounts. The followings are the key accounts:
Administrator: This provides you with the complete access to files, services, directories, and other facilities.
Guest: This is for the users who only requires occasional access. The users should be careful using this account as the system can encounter security problem.
Local System: It helps to run system processes and handle system-level tasks.
Local Service: It is used to run the services that requires less privileges.
Network Service: It is also used to run the services that requires less privileges but also access network resources.

Microsoft extends mitigation security tool for vendors
To help towards many efforts, Microsoft has declared a new mitigation security utility for application developers and information technology professionals. The Enhanced Mitigation Evaluation Toolkit (EMET), recently at Version 1.0.2, is believed as an extensible framework that will include future mitigation technologies as they are launched, according to a Microsoft blog.
This EMET release contains just four mitigations: dynamic data execution prevention, heap spray allocation, NULL page allocation and structured exception handing. EMET users can choose into these mitigations for their applications by using the command line in the utility. Users don’t have to have to reconcile their applications after using the tool, according to the blog. EMET is the latest component in Microsoft’s overall Security Development Lifecycle strategy. It permits developers to write security into applications at a more grainy or command-line level. Thus, rather of securing an entire application, programmers can code security parameters into a single process.
Security stars like the idea of going deep into the anatomy of an application instead of just depending on antivirus software or operating system security functions. For instance, the president of Lieberman Software, called EMET a good value-add for Microsoft ISVs. This contributes an extra post-production step that permits ISVs to make it much harder for hackers to overwork their applications. The extra post-production step hardens the rules for memory usage, finer grained protection and also strengthens the exclusion mechanisms.
As hackers begin to objective more on specific applications, developers have started to pay more care to embedded security. EMET is worth a try in the face of server attacks, automated bugs, browser attacks and stack-buffer overflow exploits. Every third-party partner, application developer or part time coder should at least consider checking out the new EMET from Microsoft said by the director of security at nCircle. The toolkit makes it even easier to employ the newest security improvement mitigations built into the newer Microsoft operating systems.
