Byod – Good Or Bad Or Unknown?

If you are willing to implement Bring Your Own Device (BYOD), then you must be willing to trust that your users are going to do the right thing. This element of trust needs to be in place for any BYOD environment to work effectively, or you will end up tightening the security on the device so much that it will no longer be effectively.

Windows 7 : WORKING WITH THE FIREWALL (part 6) - Using the GPO Technique - Adding a New Application Rule, Removing an Application Rule

This section describes how to create a new application rule. The approach works equally well for a port or service with a little tweaking of the example code. Rules generally provide a basis for creating an exception to the baseline rules.

Windows 7 : WORKING WITH THE FIREWALL (part 5) - Using the GPO Technique - Obtaining a List of Rules

Before you can learn much about the rule technique for working with the Windows Firewall, you must know how to enumerate the rules. The rules provide considerably more information than older Windows Firewall techniques.

Windows 7 : WORKING WITH THE FIREWALL (part 4) - Using the GPO Technique - Configuring the Rule Technique Example

The Rule Technique example performs three tasks. First, it shows how to enumerate the rules used to configure the Windows Firewall exceptions and services. You need to be able to enumerate these rules to find entries that may be helpful to your application.

Windows 7 : WORKING WITH THE FIREWALL (part 3) - Adding and Deleting Ports

In addition to providing an exemption for a port, you can also provide exemptions for applications. An application may require direct access to a Website for updates or to obtain information.

Windows 7 : WORKING WITH THE FIREWALL (part 3) - Adding and Deleting Ports

Unless you want to engage in some fancy programming, you're a bit limited on ports you can add to the Windows Firewall. For example, you can't easily create a port that provides specific user configuration information.

Windows 7 : WORKING WITH THE FIREWALL (part 2) - Modifying a Setting

You can programmatically change the Windows Firewall settings. The Remote Administration example shows how to enable and disable the Remote Administration feature of the Windows Firewall, but the same principles hold true for any setting you want to change.

Windows 7 : WORKING WITH THE FIREWALL (part 1) - Interacting with the Firewall , Verifying the Firewall Status

The Windows Firewall has a lot of settings, many of which are useful for applications to know. The Firewall Status example provides a representative example of the available settings, but it doesn't show all of them.

Windows 7 : Developing Applications with Enhanced Security - DEVISING AND IMPLEMENTING A SECURITY POLICY

You can simply configure the policy as part of your application setup, and the application will take care of configuring the system when the user installs the application. The following sections describe the ClickOnce approach in more detail.

Windows 7 : Developing Applications with Enhanced Security - CREATING AN APPLICATION WITH ENHANCED SECURITY (part 3) - Developing for Permissions

When CLR loads an assembly, the assembly lacks any rights — it can't even execute code. Consequently, the first task CLR must perform with the assembly is to use the evidence and the code group memberships to determine what permissions the assembly has.

Windows 7 : Developing Applications with Enhanced Security - CREATING AN APPLICATION WITH ENHANCED SECURITY (part 2) - Developing for Security Roles

Role-Based Security asks the question of whether some entity (a user, the system, a program) is in a particular role. If it's in that role, the entity can likely access a system resource or application feature safely.

Windows 7 : Developing Applications with Enhanced Security - CREATING AN APPLICATION WITH ENHANCED SECURITY (part 1)

Your application might trust an assembly from the MyComputer zone, but not one from the Internet zone. Likewise, you need to know the user's role. Remember that a user can wear several hats (have different roles) and that you need to tune the application to work within those roles.

Windows 7 : Developing Applications with Enhanced Security - CONSIDERING MODERN APPLICATION SECURITY REQUIREMENTS (part 3) - Working with Security Policies

Policies are an important part of working with security in the .NET Framework. The policy defines the security settings for one or more applications. When the CLR runs an application, it checks the application against the security policies and interacts with it appropriately.

Windows 7 : Developing Applications with Enhanced Security - CONSIDERING MODERN APPLICATION SECURITY REQUIREMENTS (part 2) - Adding Permissions

The permissions granted or denied by NT security present one level of security; the permissions provided by the classes in the System.Security.Permissions namespace present a second level of security. This second level provides fine-grained control over specific kinds of tasks, rather than the coarse general control provided by NT security.

Windows 7 : Developing Applications with Enhanced Security - CONSIDERING MODERN APPLICATION SECURITY REQUIREMENTS (part 1)

The concept of security zones originated with Internet Explorer, and you can still see this concept at work in the Internet Options applet shown in Figure 1. In this case, selecting a particular zone for an Internet location changes the security for that site.

Microsoft Exchange Server 2010 : Indexing Exchange Public Folders

One of the major strengths of SharePoint is its ability to index (or crawl) a variety of content sources. This index can then be searched using keywords, enabling users to find the information they seek wherever it lives.

Microsoft Exchange Server 2010 : Email Integration (part 3) - Configuring Incoming Email - Directory Management Service, Troubleshooting Incoming Email

With Directory Management Service enabled, when a list or library is enabled for incoming email, SharePoint will automatically create a mail-enabled contact for you. Figure 6 shows the configuration options when you enable this service.

Microsoft Exchange Server 2010 : Email Integration (part 2) - Configuring Incoming Email

SharePoint's incoming email delivery is a convenient way to send a message and its attachments to a list or library. This email could originate from within the organization or outside it. Let's look at a few examples of how you can use this feature.

Microsoft Exchange Server 2010 : Email Integration (part 1) - Configuring Outgoing Email

SharePoint sends email messages for a number of reasons. One is for the alert engine with SharePoint. For example, if a user is assigned a new task, they will automatically receive a new message.

D-Link HD Wireless Outdoor Cloud Camera DCS-2332L

The DCS-2332L is D-Link's highest specification outdoor camera, and the company says that the weatherproof housing will protect it from rain and dust. The resolution is specified at 720p (1Mp) and there's an extra infrared night mode that's combined with an infrared LED.

Windows 7 : Programming WMI Support (part 5) - Techniques for Testing WMI Driver Support, WMI Event Tracing

This discussion describes the WMI extensions to WDM that Kernel Mode Drivers, as information providers, can use to provide information to information consumers.

Windows 7 : Programming WMI Support (part 4) - Troubleshooting Specific WMI Problems

Unload and reload the WMI WDM Provider. For WMI data blocks registered with the WMIREG_FLAG_EXPENSIVE flag, the provider keeps a handle open to the data blocks as long as there are consumers for that block.

Windows 7 : Programming WMI Support (part 3) - Firing WMI Events

In the Featured Toaster sample driver, the ToasterFireArrivalEvent function shows how to generate a WMI event that has a dynamic instance name. The WMI event contains the name of the device model, which WMI records to log the arrival of this device.

Windows 7 : Programming WMI Support (part 2) - WMI Requirements for WDM Drivers ,WMI Class Names and Base Classes

WMI class names are case-insensitive, must start with a letter, and cannot begin or end with an underscore. All remaining characters must be letters, digits, or underscores.

Windows 7 : Programming WMI Support (part 1) - WMI Architecture, Registering as a WMI Data Provider, Handling WMI Requests

To support WMI, your driver registers as a WMI provider. A WMI provider is a Win32 dynamic-link library (DLL) that handles WMI requests and supplies WMI instrumentation data.

Parallel Programming with Microsoft Visual Studio 2010 : PLINQ Operators and Methods (part 2)

Use AsParallel and AsSequential as gates for parallel and sequential execution, as shown in the following diagram. Although it is not common, a single PLINQ query can have multiple AsParallel and AsSequential clauses.

Parallel Programming with Microsoft Visual Studio 2010 : PLINQ Operators and Methods (part 1)

You create a PLINQ query to parallelize your code. In most circumstances, the next step is to iterate the results by using a foreach or for method. At that time, the query is most likely performed by using deferred execution.

Parallel Programming with Microsoft Visual Studio 2010 : Introduction to LINQ (part 2) - PLINQ

PLINQ is the parallel version of LINQ. The objective of parallel programming is to maximize processor utilization with increased throughput in a multicore architecture.

Parallel Programming with Microsoft Visual Studio 2010 : Introduction to LINQ (part 1) - Execute a LINQ query and then iterate and display the results

The following image shows the output for the application. Notice that nothing is displayed before the foreach loop. The results are displayed after the Where method actually executes, which occurs inside the foreach loop.

LINQ to Objects : How to Join with Data in Another Sequence (part 7)

The join/into keyword combination in query expression syntax maps to the GroupJoin standard query operator. The GroupJoin operator returns a sequence of inner elements with a matching key value for every outer element in a sequence.

LINQ to Objects : How to Join with Data in Another Sequence (part 6) - One-to-Many Joins - The join Operator

A one-to-many join allows a subgroup collection of related elements to a parent element in another sequence. The most common example of a one-to-many join is a listing of Customers, each with a collection of Orders.

LINQ to Objects : How to Join with Data in Another Sequence (part 5) - One-to-One Join Performance Comparisons

Choosing the most appropriate join technique will yield large performance gains as collection size grows. To have some guidance on which technique makes sense, a simple experiment is necessary (results of such an analysis are summarized in Table 1).

LINQ to Objects : How to Join with Data in Another Sequence (part 4)

A subquery in a queries Select projection can achieve a one-to-one join. In testing, this option did not perform as well as the alternatives and should only be considered for very small (less than ten-element) sequence sizes.

LINQ to Objects : How to Join with Data in Another Sequence (part 3)

Outer joins differ from inner joins in the way they handle missing and unmatched values. An outer join will return a result for outer elements that have no matching inner elements, whereas these elements would be skipped when using an inner join

LINQ to Objects : How to Join with Data in Another Sequence (part 2) - One-to-One Joins - The join Operator

The simplest join of this type is built using the join operator in the query expression syntax, or the Join operator in extension method syntax

LINQ to Objects : How to Join with Data in Another Sequence (part 1) - Cross Joins

Cross joins project every element in one sequence against every element in a second sequence. Cross joins in LINQ to Objects ironically aren’t implemented using either of the Join operators, but rather a clever use of the SelectMany operator.

Moving into SAP Functional Development : Gaining Control of Change Control - How to Organize and Plan for Change in the Real World

To stay linked with the entities that drive or create changes, you must integrate a “change management” organization into your SAP processes and day-to-day life supporting SAP.

Moving into SAP Functional Development : Gaining Control of Change Control - Change Control and the SAP Solution Stack

A lot of work goes into configuring and assembling an SAP solution that is supported by its Solution Stack vendors and effective in servicing its end users.

Moving into SAP Functional Development : Gaining Control of Change Control - Change Control Affects Everything

To understand the role that change management plays in an enterprise mySAP solution, it is important to understand the evolution of that solution in terms of phases of systems development—these phases tie nicely into the “SAP system landscape” previously discussed.

Exchange Server 2010 : Outlook Integration (part 7) - Document Library Integration

While Outlook works best when working with lists, there are some benefits to connecting Outlook to a document library. Document libraries allow users to store files (Word, Excel, PDF, etc.) in SharePoint.
