  • ASP.NET WebAPI Security 2: Identity Architecture

    - by Your DisplayName here!
    Pedro has beaten me to the punch with a detailed post (and diagram) about the WebAPI hosting architecture. So go read his post first, then come back so we can have a closer look at what that means for security. The first important takeaway is that WebAPI is hosting independent-  currently it ships with two host integration implementations – one for ASP.NET (aka web host) and WCF (aka self host). Pedro nicely shows the integration into the web host. Self hosting is not done yet so we will mainly focus on the web hosting case and I will point out security related differences when they exist. The interesting part for security (amongst other things of course) is the HttpControllerHandler (see Pedro’s diagram) – this is where the host specific representation of an HTTP request gets converted to the WebAPI abstraction (called HttpRequestMessage). The ConvertRequest method does the following: Create a new HttpRequestMessage. Copy URI, method and headers from the HttpContext. Copies HttpContext.User to the Properties<string, object> dictionary on the HttpRequestMessage. The key used for that can be found on HttpPropertyKeys.UserPrincipalKey (which resolves to “MS_UserPrincipal”). So the consequence is that WebAPI receives whatever IPrincipal has been set by the ASP.NET pipeline (in the web hosting case). Common questions are: Are there situations where is property does not get set? Not in ASP.NET – the DefaultAuthenticationModule in the HTTP pipeline makes sure HttpContext.User (and Thread.CurrentPrincipal – more on that later) are always set. Either to some authenticated user – or to an anonymous principal. This may be different in other hosting environments (again more on that later). Why so generic? Keep in mind that WebAPI is hosting independent and may run on a host that materializes identity completely different compared to ASP.NET (or .NET in general). This gives them a way to evolve the system in the future. How does WebAPI code retrieve the current client identity? HttpRequestMessage has an extension method called GetUserPrincipal() which returns the property as an IPrincipal. A quick look at self hosting shows that the moral equivalent of HttpControllerHandler.ConvertRequest() is HttpSelfHostServer.ProcessRequestContext(). Here the principal property gets only set when the host is configured for Windows authentication (inconsisteny). Do I like that? Well – yes and no. Here are my thoughts: I like that it is very straightforward to let WebAPI inherit the client identity context of the host. This might not always be what you want – think of an ASP.NET app that consists of UI and APIs – the UI might use Forms authentication, the APIs token based authentication. So it would be good if the two parts would live in a separate security world. It makes total sense to have this generic hand off point for identity between the host and WebAPI. It also makes total sense for WebAPI plumbing code (especially handlers) to use the WebAPI specific identity abstraction. But – c’mon we are running on .NET. And the way .NET represents identity is via IPrincipal/IIdentity. That’s what every .NET developer on this planet is used to. So I would like to see a User property of type IPrincipal on ApiController. I don’t like the fact that Thread.CurrentPrincipal is not populated. T.CP is a well established pattern as a one stop shop to retrieve client identity on .NET.  That makes a lot of sense – even if the name is misleading at best. There might be existing library code you want to call from WebAPI that makes use of T.CP (e.g. PrincipalPermission, or a simple .Name or .IsInRole()). Having the client identity as an ambient property is useful for code that does not have access to the current HTTP request (for calling GetUserPrincipal()). I don’t like the fact that that the client identity conversion from host to WebAPI is inconsistent. This makes writing security plumbing code harder. I think the logic should always be: If the host has a client identity representation, copy it. If not, set an anonymous principal on the request message. Btw – please don’t annoy me with the “but T.CP is static, and static is bad for testing” chant. T.CP is a getter/setter and, in fact I find it beneficial to be able to set different security contexts in unit tests before calling in some logic. And, in case you have wondered – T.CP is indeed thread static (and the name comes from a time where a logical operation was bound to a thread – which is not true anymore). But all thread creation APIs in .NET actually copy T.CP to the new thread they create. This is the case since .NET 2.0 and is certainly an improvement compared to how Win32 does things. So to sum it up: The host plumbing copies the host client identity to WebAPI (this is not perfect yet, but will surely be improved). or in other words: The current WebAPI bits don’t ship with any authentication plumbing, but solely use whatever authentication (and thus client identity) is set up by the host. WebAPI developers can retrieve the client identity from the HttpRequestMessage. Hopefully my proposed changes around T.CP and the User property on ApiController will be added. In the next post, I will detail how to add WebAPI specific authentication support, e.g. for Basic Authentication and tokens. This includes integrating the notion of claims based identity. After that we will look at the built-in authorization bits and how to improve them as well. Stay tuned.

  • How do I create a customized keyboard layout for Windows?

    - by Pedro Palhoto
    On Linux you can create any layout you wish by editing the appropriate ASCII configuration files. On Windows the keyboard layout definitions are binary. Is there any tool that can create these binary keyboard layout configuration files? I grew up on the Macintosh international keyboard layout, which used the option key extensively, and now I would like to use the same layout on Windows. On Linux this Mac international keyboard layout exists for both the console as well as for X.Org. On Windows, the most similar layout is US International, which is not the same.

  • 1Tb disk formatted on Linux won't mount on windows nor mac

    - by Pedro MC
    I have an external HD (western digital) with 1Tb. I use Linux but I wanted to reserve a cross platform partition on the disk. I decided to create two partitions and used the "disks" application to do it. I created one partition with the LUKS (version 1) encryption and the other one, cross platform, in NTFS filesystem. Things work fine on my OS but when I try to use the disk (the cross platform partition) on both windows and mac the device is not recognized. What could it be? Next, output of "sfdisk -l /dev/sdb": Disk /dev/sdb: 121600 cylinders, 255 heads, 63 sectors/track Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End #cyls #blocks Id System /dev/sdb1 0+ 36473- 36473- 292968750 83 Linux /dev/sdb2 36473+ 121600- 85128- 683789062+ 83 Linux /dev/sdb3 0 - 0 0 0 Empty /dev/sdb4 0 - 0 0 0 Empty

  • Security in shared hosting vs VPS 'virtual appliances'

    - by Pedro Loureiro
    I have to change my hosting provider. Right now I have a shared hosting account but I'm considering trying the LAMP stack appliance from turnkeylinux.org. I'm very comfortable with using linux, I've been using it for a long time. I have no problem ssh'ing into remote machines and do whatever I have to do (coding, reading logs, moving files, deploying, etc). The problem is that none of those tasks have involved securing the server/firewall. My experience has been as a desktop user or developer deploying apps/files in remote servers. Ignoring the security in the application logic (read: any scripts, frameworks, websites I might have created or installed) - I'm worried about things like base configuration of deamons, firewall, ports, executable scripts being readable from the outside and whatnot. My question is: how do you compare the (expected) out of the box security of the LAMP stack from turnkey and the (expected) security of a "regular" shared hosting provider? I was hoping to find some guides with a list of steps to do to protect my server but the only documentation I found was simply referring to ubuntu's documentation.

  • CentOS Vulnerabilities - Exploits/Payloads

    - by Joao Heleno
    Greetings. I'm doing an academic work where I have to find vulnerabilities in CentOS and show how to take advantage of those same vulnerabilities. I'm no hacker and I'm finding this task to be of great difficulty, that is, I see all the security alerts and their descriptions but no explanation of how to take advantage. Maybe I'm being a little naive but all I want to know is if there is any tool I can use to show that CentOS 5.0 vulnerability XPTO exists and to show it "working". If possible something like CVE-2007-0001 exploit tool, CVE-2007-0002 payload and so on. Thanks.

  • Redirect local service to custom proxy

    - by Pedro Laguna
    Hello, I'm trying to create a custom proxy program but I have a problem. My program connects to a fixed port from a random port and I need to tunnel all this traffic by my local proxy. I think the solution is using iptables, but all the topics I found are related to redirect incoming connections, not outbounds. How can I redirect all the traffic from a local port to another local port and later to the internet? Thanks,

  • Network keeps disconnecting - Repairing solves it. Router configuration

    - by Joao Carlos
    My network connection keeps going insane, it will keep normal applications connected, like TeamViewer and MSN, but webpages will stop loading (Problem loading page). Everything looks connected and works like a charm, but webpages and new connections wont work. If I press "Repair" in the network connections to restart the adapter, it will work. This happens on WIRED and WIRELESS connections, both on Windows and on MacOSx. I have had this for years (different computers, routers, cities), but I never figured it out. I learn to live with it, but, I think theres probably a solution. What must I be doing wrong if this keeps happening? You guys have same thing?

  • Sync iPhone Mail with Webmail

    - by João Paulin
    I had an email account [email protected] hosted on Host A. This mailbox had 100 messages. I wanted to migrate to Host B, so I download all the 100 messages from Host A on my iPhone. Now that my site was successfully migrated to Host B and the email account [email protected] was created again (the mailbox is empty), how can I send the messages that I have downloaded on my iPhone to the mailbox on Host B? Note that the migration from Host A to Host B did not change the IMAP and SMTP adressess and parameters. I'm still using the same addresses, parameters and ports as before. The email accounts just switched hosting.

  • Different keyboard layouts at same time for different devices

    - by Joao Carlos
    I have a MacBook Pro running Snow Leopard, and I am using it as a portable but also desktop computer. In order to acheive this, I bought a VGA adapter and I am using it with an external mouse, keyboard, and monitor. The problem is, the external keyboard layout is different from the one on the macbook. It is set to US qwerty (its a logitech G15), and because of that, most keys behave differently than they should. Question is, how can I set up different layouts at same time for different devices? I want US for external keyboard and PT for the default one.

  • What hardware makes a good MongoDB Server ? Where to get it ?

    - by João Pinto Jerónimo
    Suppose you're on dell.com right now and you're buying a server to run your MongoDB database for your small startup. You will have to handle literally tens of thousands of writes and reads per minute (but small objects). Would you go for 2 processors ? Invest more on RAM ? I've heard (correct me if I'm wrong) MongoDB handles the most it can on the RAM and then flushes everything to the disk, in that case I should invest on a CPU with a large L2 cache, probably 40GB of RAM and a solid state drive.. right ? Would I be better off with a high end (~$11,309, 2 expensive processors, 96GB of RAM) server or 2x(~$6,419, 2 expensive processors, 12GB of RAM) servers ? Is Dell ok or do you have better sugestions ? (I'm outside the US, on Portugal)
