The Department of Homeland Security (DHS) Willy Adames Jersey , along with the SANS Institute and Mitre, released a scoring system on Monday designed to help enterprises verify whether the software they are using meets reasonable standards for secure coding.


The organizations released an updated list of the Top 25 most dangerous programming errors found in software, and a measuring system that lets enterprises score the security of their software based on the presence or absence of those flaws. The goal is to give enterprises information that will let them make more informed decisions regarding the security of their software, said Alan Paller, director of research at SANS.


The hope is that organizations within the private sector and government will use the Top 25 list and scoring system during the software procurement process Matt Duffy Jersey , he said. “Companies and not-for-profits that build or buy Web services and software do not have a reliable way to know whether the software they are using is protected against common attacks,“ Paller said. The key missing ingredients have been a credible, validated list of the most dangerous errors programmers make, and a way to test the software to see whether those errors are present, he said.


“The DHSMitre announcement ... is just that -- an updated Charlie Morton Jersey , authoritative list of the key flaws plus a measuring system that lets organizations score their software for security,“ Paller said. “The bottom line is that buyers and builders of software and services will be able to ask for assurance that the critical flaws have been eliminated, and be able to verify that.“ The updated Top 25 list of most dangerous programming errors that the scoring system is based on includes many of the same security issues from last year’s list.


The one key difference is that SQL Injection errors top the list for 2011, compared with last year, when they were the second most dangerous error. Operating System Command injection errors Kevin Kiermaier Jersey , which allow attackers to issue OS commands through a Web application interface, was listed as the second most dangerous software programming error in this year’s list.


Rounding out the top five threats were buffer overflow errors, cross site scripting flaws and missing authentication for critical functions. The list of errors released on Monday was accompanied with suggestions and guidance on how software developers can mitigate the chances of such flaws showing up in their products. “[These] kinds of list are good ways to focus attention on the biggest vulnerability areas,“ said John Pescatore, an analyst with Gartner.


“Things like the Common Vulnerability Scoring Standard have been around for a while providing a common framework for describing vulnerabilities and tailoring severity levels to your own environment.“ But what’s equally important are ways to measure and drive improvements in the actual implementation of security controls Avisail Garcia Jersey , he said. Efforts such as the Building Security In Maturity Model (BSIMM), for instance lets companies compare themselves and see how and whether they are improving on the security front, Pescatore said.




In most international and large-scale companies, users are often divided into several geo- graphic locations, such as Tokyo Wade Boggs Jersey , Madrid, Hong Kong, and Los Angeles. Historically, the only way to connect these locations has been via a wide area network (WAN) connection over a relatively slow bandwidth link.


In a regional design, each of these regions is assigned their own speci?c domain where they can be further MCTS Windows Server 2008 subdivided into more closely knit administrative groups. Figure 1.7 shows an example of this type of domain structure.


Sometimes when you need to isolate particular services using an autonomous model (not an isolation model!) Evan Longoria Jersey , it becomes necessary for you to create a multiple tree infrastructure wherein services or data are allocated among separate domain trees in a fashion that allows for a broader form of administration. You can see this model in action in Figure 1.8.


The main advantage of this model is that you manage to achieve a form of autonomous separation, but you also get to maintain the simplicity of a single schema. And if tHere鈥檚 one aspect of Windows Server that?s annoying to mess with, it鈥檚 the schema.


Of course, this structure has drawbacks. Specifically, if you decide to use this form of administration Throwback Tampa Bay Rays Jerseys , you remove the option to have complete isolation. Because the domain trees all are in the same forest, the root-level domain will have access to the rest of the trees and therefore will be able alter important information?something that you, as an enterprise administrator, may not want to have happen. Additionally, authentication paths usually take longer in this model because users have to cross separate servers to authenticate across links that are farther away.


Now that you鈥檝e seen the elements required to create an MCITP Enterprise Administrator effective domain infrastructure Custom Tampa Bay Rays Jerseys , I鈥檒l discuss how to put them together effectively.


The process for this, once you understand the elements involved, is rather simple. Here are the steps for domain structure creation:


1. Determine the administrative model.


_N Centralized


_N Decentralized


_N Hybrid


2. Choose a domain model.


3. Choose the number of domains.


4. Assign your domain functional levels.


5. Assign a root domain.
