What advanced security options exist for Neo4j? - authentication

Our company is considering Neo4j for a database solution. We're using to Oracle dbs, and have relied upon their built in user authentication management to control who can connect to the db, who has read or write access, and what they are allowed to view in the db.
With Neo4j, most of these security options are missing. While we don't necessarily need to control visibility of nodes and relationships on a per-user level, the lack of multiple user accounts and the inability to control read/write access per account could be a dealbreaker. While application access of Neo4j should be well-contained and secure, we want to allow read-only accounts via the browser client to our developers (at least in our dev and qa environments).
The only solution that's jumped out at us so far has been GraphAware's Enterprise Security offering. I'd like to know if there are any other solutions out there that are compatible with Neo4j 3.0. At the moment we are not considering using the Neo4j REST API.

GraphAware Enterprise Security is compatible with 3.0 and there are no other solutions as far as we are aware. That said, judging from Github activity, it looks to me like the security mechanisms in Neo4j 3.1 will be enhanced to include multiple users and LDAP integration. We have to wait for 3.1 to be out. GraphAware Enterprise will be compatible with Neo4j 3.1 and use its native security features where possible.
DISCLAIMER: I work at GraphAware.

I did find one other partial solution to this, though it has its own hoops to go through to set up.
With the Enterprise edition, in a clustered environment, a node can be configured to be a read-only slave, and configured with its own login/pass for dev use.

What is a Cheaper, more pragmatic way to store Synced Data for a UWP App?

I am building a UWP app that targets both x86, x64 and ARM platforms. I want to replace the current implementation that uses Azure for the backed (an App Service and an SQL Server) because of the high price and because my Pay-As-You-Go subscription does not allow me to set a spending limit.
I thought about using a local database but I don't know if that could be a solution since I want the user to be able to have his data synced on both PC and phone for example. I am also ok with renouncing the idea of a structured database in favor of structured files (like xml) if I can find a way to keep them somewhere in the cloud (and then I can read/write them from the client app - no need for App Service).
Are there any free, non-trial alternatives to Azure? Or should I look more into the file storage implementation? Thanks in advance.
Instead of Azure you could use another web hosting solution to publish you API. Azure also offers small free plans that might be sufficient.
An alternative would be to request access and store/sync data to user's OneDrive. Each logged in user with Microsoft Account should have OneDrive storage available so this is a good middle-ground, which is still free for you. A nice introduction to this can be found in this article.
UWP also offers RoamingFolder where you can store small files that are synced across the devices that you use. Unfortunately this is less reliable because you are not able to control when the sync happens and cannot resolve conflicts.
I have successfully migrated to another cloud platform: Heroku. In my opinion, at least for small apps, Heroku offers the best solution both technology-wise and price-wise.
I am now able to have a webservice hosted for free in the cloud, without worring about traffic and number of requests. Of course you can scale up if you want better performance, but you can start with a free plan. Also, I have a postgressql db hosted also in the cloud, also for free (up until 10 000 records, and it will be just 9$/month if I want to upgrade to 10 milion). One can never found an offer like this free on Azure.
I had to learn a bit of Node.js (there are a lot of languages Heroku supports for backend services, but .Net is not one of them) but it was totally worth it!
Another option that is now starting to gain more and more popularity is FireBase. I will certantly also check that out for my future apps.

Parse Server, purpose and benefits

I am trying to wrap my head around Parse server and have the following questions.
Is this a hosted service on AWS? and what is the benefit of using this?
What is the relationship between Parse server and MongoDB?
On the parse server site the following is stated, The Parse hosted backend will be fully retired on January 28, 2017 does this mean this is obsolete and I should avoid using this?
How do I implement security (authentication and authorization) on this?
I'll try to be brief:
The open source Parse-Server is solution that you host yourself as if it was any other web application. You can host your own instance of Parse-Server on platforms like AWS, Heroku, etc. There are lots of benefits including being able to use many more adapters (other push notification services, file storage services, etc) as well as performance improvements (no artificial limits on req/sec). Several new features are being added to the open source version that are not supported in the Facebook hosted solution.
By default Parse-Server uses MongoDB as database store (default), just like a Rails Application would use PostgreSQL as a database store. Latest Parse-Server can also use PostgreSQL as a database store.
Parse-Server is not obsolete and far from it. The shutdown date refers to the hosted solution that Facebook provided.
Parse-Server provides these features out of the box, one of the many reasons it is very popular. For this I recommend reading the documentation: http://parseplatform.github.io/docs/.
Disclaimer:
I work on the Parse Server Ruby Client SDK that is compatible with the open source server.

Why not directly connect to SQL servers from client? Why do we need application servers in client-server model?

Many applications use the following model:
Browsers or other clients interact with application servers.
Application servers (web servers or RPC servers) interact with data store servers (SQL servers or non-SQL storage).
For internet applications, they need application servers because they must keep simple feature on data servers for performance. But I can't see why they need application servers on intranet.
For example, can we develop an Adobe AIR application, which directly connect to a PostgreSQL server? I guess we can deploy a center PostgreSQL server which has many stored procedures and set strict permission, and let the Adobe AIR application fetch (and modify) data only by invoking the stored procedure.
Why don't the most of applications choose a simplier solution?
In general, there is no reason why you couldn't get an independent application to talk to a PostgreSQL server directly. Some applications do this and it works fine.
I'm not familiar enough with Adobe AIR to say whether it's possible in this context. In principle, if you can get a PostgreSQL driver, or if you can write your own using TCP sockets (the PostgreSQL network protocol is documented in details in the official documentation), you could certainly connect directly.
This being said, having a form of application server between the end-client and the database server isn't purely for performance.
Web-based development allows the SQL queries to be controlled by the server. Instead of exposing complete SQL access, you expose the features that the client can use. If you need to tweak the queries later (bug, change of data structure, ...), you can do this rather centrally on your application server, without having the need to deploy a new version of the client to each user.
Of course, you can do some abstraction like this user server programming directly, but this isn't suitable for all applications. This may depend on what other features your application needs, for example if it needs to make use of a library programmed in another language. You can use some procedural languages bindings, but it's not always suitable: pl/Python is an "untrusted" language (which may cause security problems) and pl/Java needs a external add-on, for example.
In addition, not all applications are ultimately reserved for intranet usage nowadays. It often makes sense not to restrict yourself to intranet usage when you start designing an application.
I initially started with a direct access design and quickly found it useful to move to an application server where I talked to the DB via web services. Reasons included:
Handling DB restart, local connection loss, client IP address change, etc is much easier when you're talking to the DB over a stateless protocol like HTTP. This is more of an issue for remote workers.
Transactions are clearly demarcated and isolated in server-side transactional methods (I used EJB3 and container managed transactions)
It's much easier to add new clients like a phone app as they can share more of the code and business logic. Stored procedures in the database are very useful, but can be limited and occasionally frustrating.
Some tools/languages don't have built-in tools for talking to PostgreSQL directly, but can easily talk to a RESTful web service with XML or JSON request/response format.
DB admin is easier if you're dealing only with a single application server connection pool
The main downside is of course the extra layer means extra work and extra maintenance.
You can, but...
Browser languages/libraries tend to have poor database support
What happens when someone wants to use this application remotely?
If you're not talking about browser-based applications, then that is exactly what many do. There are plenty of traditional installed client applications talking to a backend database either directly or via a wrapper (odbc/jdbc).

Enterprise SSO & Identity management / recommendations

We've discussed SSO before. I would like to re-enhance the conversation with defined requirements, taking into consideration recent new developments.
In the past week I've been doing market research looking for answers to the following key issues:
The project should should be:
Requirements
SSO solution for web applications.
Integrates into existing developed products.
has Policy based password security (Length, Complexity, Duration and co)
Security Policy can be managed using a web interface.
Customizable user interface (the password prompt and co. screens).
Highly available (99.9%)
Scalable.
Runs on Red Hat Linux.
Nice to have
Contains user Groups & Roles.
Written in Java.
Free Software (open source) solution.
None of the solutions came up so far are "killer choice" which leads me to think I will be tooling several projects (OWASP, AcegiSecurity + X??) hence this discussion.
We are ISV delivering front-end & backend application suite. The frontend is broken into several modules which should act as autonomous unit, from client point of view he uses the "application" - which leads to this discussion regrading SSO.
I would appreciate people sharing their experience & ideas regarding the appropriete solutions.
Some solutions are interesting
CAS
Sun OpenSSO Enterprise
JBoss Identity IDM
JOSSO
Tivoli Access Manager for Enterprise Single Sign-On
Or more generally speaking this list
Thank you,
Maxim.
What about FreeIPA?
"FreeIPA is an integrated security information management solution combining Linux (Fedora), 389 (formerly known as Fedora Directory Server), MIT Kerberos, NTP, DNS. It consists of a web interface and command-line administration tools."
If you focus on web applications, check out http://oauth.net/.
CAS has strong adoption, user-base, and a strong lead (who recently switched jobs, but is still comitted to the project). It is straightforward to integrate (if you're comfortable writing Java code/configuring Spring beans), and can do all your requirements, noteably:
SSO solution for web applications.
YES
Integrates into existing developed products.
YES (though some cleaner than others - but many modules are available for major products, and it supports common standards (SAML, OpenID).
has Policy based password security (Length, Complexity, Duration and co)
*YES - can easily be implemented, and some extensions to integrate with LDAP (probably the most common user store) are supported
Security Policy can be managed using a web interface.
NO - though one could be build fairly simply - if you're comfortable with development, and given that this is likely to be a non-trivial project, I'd recommend considering this a non-blocker given that the product is open-source
Customizable user interface (the password prompt and co. screens).
YES - easily customized through some basic HTML/CSS editing
Highly available (99.9%)
YES - both reliable, and can support multiple node/failover scenarios easily
Scalable.
YES - used in many high-traffic environments both intranet and internet
Runs on Red Hat Linux.
YES
Oracle Enterprise Single Sign-On is not what you're after - it requires a Windows executable to be deployed. Oracle Access Manager is closer to what you're after (though it's not free or Java-based).
The major commercial players in the Identity and Access Management (IAM) market space are CA, Oracle, IBM, Sun and Novell. None of these are free solutions but they have many of the features that you are looking for.
For free software, I recommend DACS: The Distributed Access Control System. I know that one department where I work has implemented this with great success. It doesn't have as many features the commercial IAM products but otherwise is a good solution.
I have used Tivoli Access Manager backing onto Websphere and IIS boxes - the way it writes access information into the page headers is very useful. On the downside, I didnt find the DB2 Ldap backend very scalable or reliable, and you know with IBM this isn't going to come cheap.
Also the asynchronous paths (junctions) used to identify different servers is a bit of a hack really eg http://mysite/myserver/myapp - a very bad idea and not thought through very well.

Know of SSO turnkey Appliance with ldap, radius, openid, etc?

I'm helping a typical small company that started with a couple of outsourced systems (google apps, svn/trac). added an internal jabber server (ejabber for mostly iChat clients). subscribes to a couple of webservices (e.g. highrisehq). and has a vpn service provided by a pfsense freebsd firewall.
And the net result of all this is that they're drowning in passwords and accounts.
It seems that if they had a single unified login / single signon service they could go a long way to combining these. E.g.: ldap as the master repository, radius linked to it for vpn, ejabber and even WPA2 wireless access, plugins for google app sign on, and perhaps an openid server for external websites like highrisehq.
It seems that all these tools exist separately, but does anyone know of a single box that combines them with a nice GUI and auto-updates? (e.g. like pfsense/m0n0wall for firewalls, freeNAS for storage). It doesn't have to be FOSS. A paid box would be fine too.
I figure this must exist. Microsoft's Active Directory is likely one solution but they'd rather avoid Windows if possible. There seem to be various "AAA" servers that ISPs use or for enterprise firewall/router management, but that doesn't seem quite right.
Any obvious solutions I'm missing? Thanks!
It's been over a year since you originaly asked the question, so I'm guessing you've solved your problem by now. But if someone else is interested in a possible solution I suggest the following:
First of all, I don't know of any "all in one" solution to your problem. However it's quite easy to combine three products that will solve all of your needs and provide a single source for User management and password storage.
The first thing to do is install an LDAP Directory to manage Users and Groups (and possibly other objects outside the scope of your question). This can be OpenLDAP, Apache DS, Microsoft Active Directory, etc. Basically any LDAP Server will do.
Second I recommend installing FreeRADIUS with the LDAP Directory configured as it's backend Service.
Third get a license of Atlassian Crowd. It provides OpenID and Google Apps authentication. Prices for up to 50 Users start at $10 and go all the way up to $8000 for an unlimited user license.
Installation and Configuration of the three is relatively easy. You'll probably put most work into creating your Users and Groups. You can install all three components on a single Server and end up with a box that allows you to authenticate pretty much everything from Desktop Login, over Google Apps and other Web Apps, down to VPN and even Switch, WiFi and Router Login.
Just make sure you configure your Roles and Groups wisely! Otherwise you might end up with some Sales Person being able to do administration on your Firewalls and Routers :-)
I would encourage anyone searching for this type of solution to check out the Gluu Server (http://gluu.org).
Each Gluu Server includes a SAML IDP for SAML SSO, an OpenID Connect Provider (OP) for OpenID Connect SSO, an UMA Policy Decision Point (PDP) for web access management, and a RADIUS and LDAP server.
All the components of the Gluu Server are open source (i.e. Shibboleth, OX, FreeRADIUS, OpenDJ, etc.), including the oxTrust web user interface for managing each component of the server.
For commercial implementations, Gluu will build, support, and monitor this stack of software on a clients VM.
You may not want to standardise passwords across so many apps (especially external ones), though for internal ones using an auth service like LDAP makes sense.
You could solve the issue of remembering passwords with an eSSO like Novell SecureLogin
Also you might be interested in Novell Access Manager and Novell Identity Manager
I too could use such a device, however the only one I could find was a (possibly outdated) data sheet from Infoblox. They seem to have since concentrated on automated network managment and I can't find the LDAP appliance on their current website. I guess building a linux box with the FOSS stuff mentioned above is what everyone does, but it would be great not to have power supplies, disks, fans etc. I suppose you could use something like an EEE PC and put the config on a flash card.
This is something I was looking for as well, and http://www.turnkeylinux.org/openldap looks like the solution: "appliance" installation, and it includes encrypted online backup which is easily restored to a new or replacement machine.
