Neo4j Account Restriction and Multiple Databases - neo4j

I know that we can get access to Neo4j db remotely by adding IP addresses. I am wondering if Neo4j supports account verification like username and password to double increase the db security even though we log in at trusted IP.
In addition, can we set mulitple databases and switch them before we query some stuff? I know Neo4jCP can do it but it only supports windows. Is there any way else to do it and is it possible that Neo4j intergrates this feature?
Thank you!

Unfortunately out of the box Neo4j doesn't support multiple databases or user management or data level security.
You can add something like that in your application layer, or use a framework like http://structr.org which provides user-management and data level security.

Is it possible to request data from Neo4j database without authentication?

I am using Javascript Bolt Driver on Google Cloud Functions to query Neo4j database and then send the result to the client, is it possible to access the database without authentication?, does the authentication slow down the query time between Client and Server?.
It is possible to disable authentication/authorization in neo4j.conf file:
dbms.security.auth_enabled=false
However it is strongly recommended to leave it on as it makes whole database accessible to anyone with access to the host and port (bolt or http). Even in environments where you can limit the access to the machine to particular network or range of IPs it is better to keep the authentication on as additional layer of protection.
The performance impact is negligible compared to all other variables usually involved (network, disk access, query planning and execution).

Give access to RDS database

i have several databases running in RDS Service.
I'd like to know the best pratice to grant access to developers to these DB.
I tought a solution using jenkins but i dont think this is the best option.
I am trying to avoid give some password to developers.
Hope you can help me.
As #ceejayoz mentioned you can create a few users with restricted privileges, for example an user who only can run selects on few schemas, another user who can update registers in a few tables.
I can share what we do and what I've seen. We do A and use B where it is easy.
A) Standard Users
For all databases, we have 3 standard users with the following suffixes (_dba, _rw, _ro). Those all have their own passwords using a strong password generator.
_dba is used to deploy scheme and has all rights
_rw is used by the application (CRUD on all tables, but can't modify scheme)
_ro only has R on all tables and generally given to developers
Note: Developers have access to a bastion used for port forwarding and proxycap. They can query the RDS endpoints from their own machines (DB Tools) going through socks proxy and bastion.
This is lazy method - since creation of users is done programmatically and we feel comfortable giving some developers read only access. They could write a bad query and slow down system, but they could do that with a specific user so not much different and the bastion logs tell me who really was in if I had to investigate.
B) UI
Simple web app with login (ideally MFA) - that provides a way to run queries. If only for reporting, ideally against R/O copy of system. Stackoverflow offers one themselves (https://data.stackexchange.com/).
What would be nice is if RDS offered this themselves (linked to your IAM roles). They offer this on RDS Serverless (https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/query-editor.html) and it may be a feature in other RDS versions. That allows fine control or even lazy control (IAM groups).

WIF - Federated Provider with multiple Identity Providers - store IP info in db?

So despite the warnings, I think I need to build a custom STS. We will support an arbitrary number of customers who provide identity information via SAML.
What is the best practice to store details on each IP? Most examples seem to store this info in the STS's web.config. That seems like it wouldn't scale real well.
Is there an obvious reason not to just store this stuff in a db and load it when the requests come in?
Fundamentally, if the Identity Providers will change over time, such as via some online administration function, rather than a new application deployment, it makes total sense to store the information in a database (or other Storage).
I think this is a potential issue for any multi-tenanted service that is federating identity with the customer.
ADFS v2.0 (which is Microsoft's STS product) stores its details in either a SQL Server DB (or SQL Server DB farm) or a Windows Internal DB. So if it's good enough for Microsoft ...

Suggestions for a practical User Authentication System?

I hate to re-invent the wheel so I'm looking for an existing solution to create a simple authentication system for my application. I've experimented for a while with using CardSpace or OpenID inside the application but I can't convince management that these would be working solutions.
Of course, I could just build a simple login dialog where username, domain and (hashed) password is stored inside a database table and I've done such a thing many times already. I hate this solution since I feel it's just a weak option. And I don't want to spend too much time trying to make the whole logon system as secure as possible, especially since I suspect that there should be existing solutions for this.
So, next to OpenID/OpenAuth and CardSpace, are there any other Authentication solutions that can be used from a Delphi/WIN32 application?
Right now, the application will be used by many customers. Most are single-user environments, although it's likely that some of those will start to have two to 5 users once this authentication system is added. But we want to support a customer who needs to allow about 500 different users on the same application. These are spread over about 100 offices but they all connect to the same SQL Server database. (MS Access right now, but we're making it possible for this user to use SQL Server instead.) To make matters even more interesting, the customer uses Citrix to centralize the user systems and the application has straight access to the SQL Server database. It's not an ideal setup but then again, the customer isn't really paying for this. We're just setting up a test environment. A proof-of-concept which the customer will test for us. Flaws will be solved later on. But right now I need quick solutions and one of them is a practical authentication system where I don't have to write a lot of code.
Have you considered using SQL Server authentication and not allowing authentication for those using an Access Database?
If you use the new SQL Server Native Client and SQL Server 2005 you can have passwords expire and change them from your client application. All of the tools to create and manage user accounts are built into SQL Server Management Studio. And if you decide later to support Windows Authentication you just need to modify your connection string.
We have a system where users on the network use Windows Authentication so they don't need to worry about another user name and password. For users that access the system via a VPN and non-domain joined machines they use SQL Authentication.
Here is the MSDN Page that talks about dealing with passwords programmatically in SQL Server 2005
You do need to make sure that SQL Server Native Client is installed, but that is simple compared to the rest of ADO.
I would suggest then
Delphi - since you are using Delphi :)
Open source - since you need to be able to figure out what is wrong if there is a problem, you probably want it cheap.
So, here are some solutions:
http://www.torry.net/pages.php?id=313
CoWindowsAccount v.1.0
SSecurity v.1.2.1.3
http://free-password-manager-plus.software.informer.com/1.6/
It might work for your purposes, but why not ask Windows for the current domain and user name, and use them as unique IDs. Windows has already done the authentication, and it saves the users making up new passwords or anything. I've used this to good effect. I also made it optional to include the machine name in the ID, so that the same user on different computers would also be unique.

Rails Subdomain Clustering

I am about to be writing a Ruby on Rails app which will use sub-domains to authenticate users. We will have two types of accounts:
user accounts
domain accounts
Users will thus be able to belong to multiple domain accounts using the same credentials. I hope to have the ability for a domain account administrator to be able to search for particular users and add them to their domain.
In addition to simply creating a domain account in the database, I want to setup an actual account on the machine (linux-based) so that users can drop files into a special directory and we can run some scripts to import that new data. Alternatively, I may write a client/server script to make this process easier.
All of this I believe I can do, however, as soon as the project attains a certain number of domain accounts, it will be necessary to figure out how to cluster the domain accounts appropriately so that we can have multiple machines.
From a database standpoint, this is fairly easy and there are lots of tutorials on how to cluster MySQL or whichever SQL server I decide to use. So my question really pertains more to machine accounts as well as how to cluster a Rails app.
If you want a comparison, think of this project like GitHub or Beanstalk but with data that isn't source control related.
Does anybody have any experience with this or know of any really good articles/books to get me started?
Thanks very much!
I suggest you look at using one of the PAM modules that lets you do account authentication against a SQL database. That way you just add the domain account to the SQL database and you get UNIX accounts (on all your servers) automagically, for free. So the clustering should just happen for free too...
