  • How can i enter in Network Security Field

    - by Master
    I am thinking of Entering in Network Security Field. It can be securing windows network , linux network But exactly don't ave the full picture how does that area is divided I only have the vague idea. i want some position where company call me to check their system to see if its secure. Or govt can hire to secure network from external access. Any thing like that Can anyone give me some idea how can i start. Is there any scope in that area. How its growing in future.

  • Window Servers 2003 Security After Support Lifecycle

    - by Daniel Fukuda
    Hello, I wanted to ask if let's say that Microsoft has stopped supporting Windows Server 2003 now so there is no any security updates and I use that system for Domain Controller (Windows XP/7 Professional Clients) and File Server only + I'm using ESET NOD23 AntiVirus. Will my system be secure? I'm asking because I don't surf internet on that system nor I will install/open any programs/documents and that server is connected to router without any open ports. "On July 14, 2015, all Windows 2003 support, including security updates and security-related hotfixes, will be terminated."

  • File auditing software for Windows Server 2003

    - by David Collantes
    I am looking for a program or program suite that will allow the auditing of network shared resources (specifically storage space), and render reports (who created, deleted, moved, modified files, etc). Yes, I know I can turn on auditing on Windows, but the Event Log isn't quite the "charmer" for the job.

  • SQL SERVER – Importing CSV File Into Database – SQL in Sixty Seconds #018 – Video

    - by pinaldave
    Importing data into database is one of the most important tasks. I often receive questions regarding what is the quickest way to insert CSV data or how to import CSV Data into SQL Server Table. Honestly the process is very simple and the script is even simpler. In today’s SQL in Sixty Seconds Video we will learn how quickly we can insert CSV data into SQL Server. The steps to import CSV are very simple. Create Table Use Bulk Insert to import the data Verify the data Done! Absolutely it is that simple.

  • SQL SERVER – Remove Debug Button in SSMS – SQL in Sixty Seconds #020 – Video

    - by pinaldave
    SQL in Sixty Seconds is indeed tremendous fun to do. Every week, we try to come up with some new learning which we can share in Sixty Seconds. In this busy world, we all have sixty seconds to learn something new – no matter how much busy we are. In this episode of the series, we talk about another interesting feature of SQL Server Management Studio. In SQL Server Management Studio (SSMS) we have two button side by side. 1) Execute (!) and 2) Debug (>). It is quite confusing to a few developers. The debug button which looks like a play button encourages developers to click on the same thinking it will execute the code. Also developer with a Visual Studio background often click it because of their habit. However, Debug button is not the same as Execute button. In most of the cases developers want to click on Execute to run the query but by mistake they click on Debug and it wastes their valuable time. It is very easy to fix this. If developers are not frequently using a debug feature in SQL Server they should hide it from the toolbar itself. This will reduce the chances to incorrectly click on the debug button greatly as well save lots of time for developer as invoking debug processes and turning it off takes a few extra moments. In this Sixty second video we will discuss how one can hide the debug button and avoid confusion regarding execution button. I personally use function key F5 to execute the T-SQL code so I do not face this problem that often.

  • Taking the fear out of a Cloud initiative through the use of security tools

    - by user736511
    Typical employees, constituents, and business owners  interact with online services at a level where their knowledge of back-end systems is low, and most of the times, there is no interest in knowing the systems' architecture.  Most application administrators, while partially responsible for these systems' upkeep, have very low interactions with them, at least at an operational, platform level.  Of greatest interest to these groups is the consistent, reliable, and manageable operation of the interfaces with which they communicate.  Introducing the "Cloud" topic in any evolving architecture automatically raises the concerns for data and identity security simply because of the perception that when owning the silicon, enterprises are not able to manage its content.  But is this really true?   In the majority of traditional architectures, data and applications that access it are physically distant from the organization that owns it.  It may reside in a shared data center, or a geographically convenient location that spans large organizations' connectivity capabilities.  In the end, very often, the model of a "traditional" architecture is fairly close to the "new" Cloud architecture.  Most notable difference is that by nature, a Cloud setup uses security as a core function, and not as a necessary add-on. Therefore, following best practices, one can say that data can be safer in the Cloud than in traditional, stove-piped environments where data access is segmented and difficult to audit. The caveat is, of course, what "best practices" consist of, and here is where Oracle's security tools are perfectly suited for the task.  Since Oracle's model is to support very large organizations, it is fundamentally concerned about distributed applications, databases etc and their security, and the related Identity Management Products, or DB Security options reflect that concept.  In the end, consumers of applications and their data are to be served more safely in a controlled Cloud environment, while realizing the many cost savings associated with it. Having very fast resources to serve them (such as the Exa* platform) makes the concept even more attractive.  Finally, if a Cloud strategy does not seem feasible, consider the pros and cons of a traditional vs. a Cloud architecture.  Using the exact same criteria and business goals/traditions, and with Oracle's technology, you might be hard pressed to justify maintaining the technical status quo on security alone.

  • Setting Sql server security rights for multiple situations

    - by DanDan
    We have an application which uses an instance of Sql Server locally for its backend storage. The administrator windows login has had its sysadmin right revoked, and instead two sql logins have been created; one for the application with a secret password and one read only login we let users view the raw data with. This was working fine until we moved on FileStreams, which requires intergrated windows authentication. So now the sql server logins must be replaced. As a result, I am now reviewing all of our logins but I am not sure how it is possible. It seems that the application needs full read/write access, yet I still need to lock down writing to the tables so the user cannot login into the database and delete data randomly. Does anyone have any tips for setting multiple levels of security using intergrated windows logins, or can you direct me to any further reading? Some answers can also be found on serverfault: http://serverfault.com/questions/138763/setting-sql-server-security-rights-for-multiple-situations

    The problem I have been trying to install SQL Server 2012 on Windows Server 2012. I continually get the same error: Managed SQL Server Installer has stopped working Problem signature: Problem Event Name: CLR20r3 Problem Signature 01: scenarioengine.exe Problem Signature 02: 11.0.3000.0 Problem Signature 03: 5081b97a Problem Signature 04: Microsoft.SqlServer.Chainer.Setup Problem Signature 05: 11.0.3000.0 Problem Signature 06: 5081b97a Problem Signature 07: 18 Problem Signature 08: 0 Problem Signature 09: System.IO.FileLoadException OS Version: 6.2.9200.2.0.0.272.79 Locale ID: 1033 Additional Information 1: c319 Additional Information 2: c3196e5863e32e0baf269d62f56cbc70 Additional Information 3: 422d Additional Information 4: 422d950c58f4efd1ef1d8394fee5d263 What I've tried After initial googling, I've tried the following things: Go through the list of hardware and software pre-reqs.

  • Performance problem with Win Server 2008 at vbox on Ubuntu 9.10 Server

    - by Diskilla
    Hey, i´ve got an Ubuntu 9.10 Server and tried to install Windows Server 2008 in a virtual machine. The Problem is, the Server has got 8 cores, but the virtual machine seems to have problems with that. The VM is very slow and not really usable if i set the VM-config to more than one core. Is it set to only one core everything works fine, but thats not a solution because I bought the Server with several cores for a reason... Does anybody know this problem or has got a solution? I feel like I read the entire internet via Google... no solution found. Greetz Diskilla P.S.: I´m from Germany and it´s kind of hard to ask in english :-) I hope I din´t make that much mistakes.

  • Windows Server 2008 R2 Server Core with AD Role having GUI Admin Console

    - by Robert Koritnik
    I would like to setup a machine with Windows Server 2008 R2 Server Core and install following server roles: Active Directory Domain Services Active Directory Federation Services Active Directory Lightweight Directory Services (I'm not sure whether I actually need this one - see note below) I'm obviously going to install Enterprise Edition. Question Can I have an AD administration graphical user interface to manage Active Directory on Server Core machine? I would really like to have it, because I'm not so keen to do stuff using power-shell, because I've never managed AD as well, so a GUI would be much more helpful, because I could at least visualize it a bit better and maybe understand AD structures. Note: I'm setting up development environment machine as well and installing Sharepoint Foundation 2010 on in so it would use this AD machine.

  • Connection to SQL Server 2008 R2 Database Server is SLOW

    - by AbeP
    The database server is a VM running SQL Server 2008 R2 on top of Windows Server 2012, 24GB RAM allocated and 2TB of disk space. Overall, the database connections are very slow and one thing that stands out is that the connection to the database server via SSMS takes 5-10 seconds. On other much less powerful servers, it takes 1-2 seconds. The VM is technically way more powerful than other machines, but the connection to the server is too slow. So, my guess is the issue is network related, but any clues on where I should be looking? Thanks!

    I do not understand the following article profound. http://msdn.microsoft.com/en-us/library/ms175915(SQL.90).aspx "In contrast, if a SQL Server user logs on by using Windows Authentication, the user can read only those files that can be accessed by the user account, regardless of the security profile of the SQL Server process." What if i define a SQL-Agent Job to perform this bulk-Insert; Is it the OWNER of the Job who gives the security-context?

  • What is New in ASP.NET 4.0 Code Access Security

    - by Xiaohong
    ASP.NET Code Access Security (CAS) is a feature that helps protect server applications on hosting multiple Web sites, ASP.NET lets you assign a configurable trust level that corresponds to a predefined set of permissions. ASP.NET has predefined ASP.NET Trust Levels and Policy Files that you can assign to applications, you also can assign custom trust level and policy files. Most web hosting companies run ASP.NET applications in Medium Trust to prevent that one website affect or harm another site etc. As .NET Framework's Code Access Security model has evolved, ASP.NET 4.0 Code Access Security also has introduced several changes and improvements. The main change in ASP.NET 4.0 CAS In ASP.NET v4.0 partial trust applications, application domain can have a default partial trust permission set as opposed to being full-trust, the permission set name is defined in the <trust /> new attribute permissionSetName that is used to initialize the application domain . By default, the PermissionSetName attribute value is "ASP.Net" which is the name of the permission set you can find in all predefined partial trust configuration files. <trust level="Something" permissionSetName="ASP.Net" /> This is ASP.NET 4.0 new CAS model. For compatibility ASP.NET 4.0 also support legacy CAS model where application domain still has full trust permission set. You can specify new legacyCasModel attribute on the <trust /> element to indicate whether the legacy CAS model is enabled. By default legacyCasModel is false which means that new 4.0 CAS model is the default. <trust level="Something" legacyCasModel="true|false" /> In .Net FX 4.0 Config directory, there are two set of predefined partial trust config files for each new CAS model and legacy CAS model, trust config files with name legacy.XYZ.config are for legacy CAS model: New CAS model: Legacy CAS model: web_hightrust.config legacy.web_hightrust.config web_mediumtrust.config legacy.web_mediumtrust.config web_lowtrust.config legacy.web_lowtrust.config web_minimaltrust.config legacy.web_minimaltrust.config   The figure below shows in ASP.NET 4.0 new CAS model what permission set to grant to code for partial trust application using predefined partial trust levels and policy files:    There also some benefits that comes with the new CAS model: You can lock down a machine by making all managed code no-execute by default (e.g. setting the MyComputer zone to have no managed execution code permissions), it should still be possible to configure ASP.NET web applications to run as either full-trust or partial trust. UNC share doesn’t require full trust with CASPOL at machine-level CAS policy. Side effect that comes with the new CAS model: processRequestInApplicationTrust attribute is deprecated  in new CAS model since application domain always has partial trust permission set in new CAS model.   In ASP.NET 4.0 legacy CAS model or ASP.NET 2.0 CAS model, even though you assign partial trust level to a application but the application domain still has full trust permission set. The figure below shows in ASP.NET 4.0 legacy CAS model (or ASP.NET 2.0 CAS model) what permission set to grant to code for partial trust application using predefined partial trust levels and policy files:     What $AppDirUrl$, $CodeGen$, $Gac$ represents: $AppDirUrl$ The application's virtual root directory. This allows permissions to be applied to code that is located in the application's bin directory. For example, if a virtual directory is mapped to C:\YourWebApp, then $AppDirUrl$ would equate to C:\YourWebApp. $CodeGen$ The directory that contains dynamically generated assemblies (for example, the result of .aspx page compiles). This can be configured on a per application basis and defaults to %windir%\Microsoft.NET\Framework\{version}\Temporary ASP.NET Files. $CodeGen$ allows permissions to be applied to dynamically generated assemblies. $Gac$ Any assembly that is installed in the computer's global assembly cache (GAC). This allows permissions to be granted to strong named assemblies loaded from the GAC by the Web application.   The new customization of CAS Policy in ASP.NET 4.0 new CAS model 1. Define which named permission set in partial trust configuration files By default the permission set that will be assigned at application domain initialization time is the named "ASP.Net" permission set found in all predefined partial trust configuration files. However ASP.NET 4.0 allows you set PermissionSetName attribute to define which named permission set in a partial trust configuration file should be the one used to initialize an application domain. Example: add "ASP.Net_2" named permission set in partial trust configuration file: <PermissionSet class="NamedPermissionSet" version="1" Name="ASP.Net_2"> <IPermission class="FileIOPermission" version="1" Read="$AppDir$" PathDiscovery="$AppDir$" /> <IPermission class="ReflectionPermission" version="1" Flags ="RestrictedMemberAccess" /> <IPermission class="SecurityPermission " version="1" Flags ="Execution, ControlThread, ControlPrincipal, RemotingConfiguration" /></PermissionSet> Then you can use "ASP.Net_2" named permission set for the application domain permission set: <trust level="Something" legacyCasModel="false" permissionSetName="ASP.Net_2" /> 2. Define a custom set of Full Trust Assemblies for an application By using the new fullTrustAssemblies element to configure a set of Full Trust Assemblies for an application, you can modify set of partial trust assemblies to full trust at the machine, site or application level. The configuration definition is shown below: <fullTrustAssemblies> <add assemblyName="MyAssembly" version="1.1.2.3" publicKey="hex_char_representation_of_key_blob" /></fullTrustAssemblies> 3. Define <CodeGroup /> policy in partial trust configuration files ASP.NET 4.0 new CAS model will retain the ability for developers to optionally define <CodeGroup />with membership conditions and assigned permission sets. The specific restriction in ASP.NET 4.0 new CAS model though will be that the results of evaluating custom policies can only result in one of two outcomes: either an assembly is granted full trust, or an assembly is granted the partial trust permission set currently associated with the running application domain. It will not be possible to use custom policies to create additional custom partial trust permission sets. When parsing the partial trust configuration file: Any assemblies that match to code groups associated with "PermissionSet='FullTrust'" will run at full trust. Any assemblies that match to code groups associated with "PermissionSet='Nothing'" will result in a PolicyError being thrown from the CLR. This is acceptable since it provides administrators with a way to do a blanket-deny of managed code followed by selectively defining policy in a <CodeGroup /> that re-adds assemblies that would be allowed to run. Any assemblies that match to code groups associated with other permissions sets will be interpreted to mean the assembly should run at the permission set of the appdomain. This means that even though syntactically a developer could define additional "flavors" of partial trust in an ASP.NET partial trust configuration file, those "flavors" will always be ignored. Example: defines full trust in <CodeGroup /> for my strong named assemblies in partial trust config files: <CodeGroup class="FirstMatchCodeGroup" version="1" PermissionSetName="Nothing"> <IMembershipCondition    class="AllMembershipCondition"    version="1" /> <CodeGroup    class="UnionCodeGroup"    version="1"    PermissionSetName="FullTrust"    Name="My_Strong_Name"    Description="This code group grants code signed full trust. "> <IMembershipCondition      class="StrongNameMembershipCondition" version="1"       PublicKeyBlob="hex_char_representation_of_key_blob" /> </CodeGroup> <CodeGroup   class="UnionCodeGroup" version="1" PermissionSetName="ASP.Net">   <IMembershipCondition class="UrlMembershipCondition" version="1" Url="$AppDirUrl$/*" /> </CodeGroup> <CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="ASP.Net">   <IMembershipCondition class="UrlMembershipCondition" version="1" Url="$CodeGen$/*"   /> </CodeGroup></CodeGroup>   4. Customize CAS policy at runtime in ASP.NET 4.0 new CAS model ASP.NET 4.0 new CAS model allows to customize CAS policy at runtime by using custom HostSecurityPolicyResolver that overrides the ASP.NET code access security policy. Example: use custom host security policy resolver to resolve partial trust web application bin folder MyTrustedAssembly.dll to full trust at runtime: You can create a custom host security policy resolver and compile it to assembly MyCustomResolver.dll with strong name enabled and deploy in GAC: public class MyCustomResolver : HostSecurityPolicyResolver{ public override HostSecurityPolicyResults ResolvePolicy(Evidence evidence) { IEnumerator hostEvidence = evidence.GetHostEnumerator(); while (hostEvidence.MoveNext()) { object hostEvidenceObject = hostEvidence.Current; if (hostEvidenceObject is System.Security.Policy.Url) { string assemblyName = hostEvidenceObject.ToString(); if (assemblyName.Contains(“MyTrustedAssembly.dll”) return HostSecurityPolicyResult.FullTrust; } } //default fall-through return HostSecurityPolicyResult.DefaultPolicy; }} Because ASP.NET accesses the custom HostSecurityPolicyResolver during application domain initialization, and a custom policy resolver requires full trust, you also can add a custom policy resolver in <fullTrustAssemblies /> , or deploy in the GAC. You also need configure a custom HostSecurityPolicyResolver instance by adding the HostSecurityPolicyResolverType attribute in the <trust /> element: <trust level="Something" legacyCasModel="false" hostSecurityPolicyResolverType="MyCustomResolver, MyCustomResolver" permissionSetName="ASP.Net" />   Note: If an assembly policy define in <CodeGroup/> and also in hostSecurityPolicyResolverType, hostSecurityPolicyResolverType will win. If an assembly added in <fullTrustAssemblies/> then the assembly has full trust no matter what policy in <CodeGroup/> or in hostSecurityPolicyResolverType.   Other changes in ASP.NET 4.0 CAS Use the new transparency model introduced in .Net Framework 4.0 Change in dynamically compiled code generated assemblies by ASP.NET: In new CAS model they will be marked as security transparent level2 to use Framework 4.0 security transparent rule that means partial trust code is treated as completely Transparent and it is more strict enforcement. In legacy CAS model they will be marked as security transparent level1 to use Framework 2.0 security transparent rule for compatibility. Most of ASP.NET products runtime assemblies are also changed to be marked as security transparent level2 to switch to SecurityTransparent code by default unless SecurityCritical or SecuritySafeCritical attribute specified. You also can look at Security Changes in the .NET Framework 4 for more information about these security attributes. Support conditional APTCA If an assembly is marked with the Conditional APTCA attribute to allow partially trusted callers, and if you want to make the assembly both visible and accessible to partial-trust code in your web application, you must add a reference to the assembly in the partialTrustVisibleAssemblies section: <partialTrustVisibleAssemblies> <add assemblyName="MyAssembly" publicKey="hex_char_representation_of_key_blob" />/partialTrustVisibleAssemblies>   Most of ASP.NET products runtime assemblies are also changed to be marked as conditional APTCA to prevent use of ASP.NET APIs in partial trust environments such as Winforms or WPF UI controls hosted in Internet Explorer.   Differences between ASP.NET new CAS model and legacy CAS model: Here list some differences between ASP.NET new CAS model and legacy CAS model ASP.NET 4.0 legacy CAS model  : Asp.net partial trust appdomains have full trust permission Multiple different permission sets in a single appdomain are allowed in ASP.NET partial trust configuration files Code groups Machine CAS policy is honored processRequestInApplicationTrust attribute is still honored    New configuration setting for legacy model: <trust level="Something" legacyCASModel="true" ></trust><partialTrustVisibleAssemblies> <add assemblyName="MyAssembly" publicKey="hex_char_representation_of_key_blob" /></partialTrustVisibleAssemblies>   ASP.NET 4.0 new CAS model: ASP.NET will now run in homogeneous application domains. Only full trust or the app-domain's partial trust grant set, are allowable permission sets. It is no longer possible to define arbitrary permission sets that get assigned to different assemblies. If an application currently depends on fine-tuning the partial trust permission set using the ASP.NET partial trust configuration file, this will no longer be possible. processRequestInApplicationTrust attribute is deprecated Dynamically compiled assemblies output by ASP.NET build providers will be updated to explicitly mark assemblies as transparent. ASP.NET partial trust grant sets will be independent from any enterprise, machine, or user CAS policy levels. A simplified model for locking down web servers that only allows trusted managed web applications to run. Machine policy used to always grant full-trust to managed code (based on membership conditions) can instead be configured using the new ASP.NET 4.0 full-trust assembly configuration section. The full-trust assembly configuration section requires explicitly listing each assembly as opposed to using membership conditions. Alternatively, the membership condition(s) used in machine policy can instead be re-defined in a <CodeGroup /> within ASP.NET's partial trust configuration file to grant full-trust.   New configuration setting for new model: <trust level="Something" legacyCASModel="false" permissionSetName="ASP.Net" hostSecurityPolicyResolverType=".NET type string" ></trust><fullTrustAssemblies> <add assemblyName=”MyAssembly” version=”1.0.0.0” publicKey="hex_char_representation_of_key_blob" /></fullTrustAssemblies><partialTrustVisibleAssemblies> <add assemblyName="MyAssembly" publicKey="hex_char_representation_of_key_blob" /></partialTrustVisibleAssemblies>     Hope this post is helpful to better understand the ASP.Net 4.0 CAS.

  • How to create SQL Server Express DB from SQL Server DB

    - by jeff
    I have a SQL Server 2008 DB. I want to extract SOME tables (and associated schema, constraints, indexes, etc) and create a SQL Server Express DB. It isn't a sync of the target, we stomp on it. We ONLY need to do this in the file system (not across the wire). We are not fond of the synchronization stuff and at this point don't know how to run SSIS. We are a C# shop and a little code is ok. Like using the C# bulk import stuff, but that won't create the schema. Suggestions?
