At first, I'm using service account with delegated credentials executing Apps Script API to run a function on Google Apps Script from a Python script via Google's Python client library, and it just works fine.
I'd like to add some IP restriction for it, to make sure it can only execute by the specific IP.
I have tried to add a firewall rule in VPC, which deny all ingress from 0.0.0.0/0 and set the target to the service account. However, running the script after setting the vpc rule is no different than before it.
The firewall rule seems to only target the VM instance used by the service account.
Is there any better way to set IP restriction for service account?
You can't restrict access to APIs based on the requestor IP, only through IAM permissions (with service accounts). Therefore you cannot configure the service account to be used only from a specific IP address.
As mentioned here : “is a special type of Google account that belongs to your application or a virtual machine (VM), instead of to an individual end user.” I ignore the reason why you are looking to restrict by IP but please keep in mind that the service account uses the private key which should not be shared between environments/users/apps, should be stored in a safe place and must used only in the server(s) running the application.

I have a service on Cloud Run (Service A) who is trying to call another service on Cloud Run (Service B). Both the services are in us-east1.
For Service B, Ingress is set to 'Allow internal traffic only' and Authentication is set to 'Allow unauthenticated invocations.
I created a Serverless VPC Connector in the same region as the services and set the IP address range to 10.8.0.0/28.
I then connected Service A to the connector mentioned above and set 'Route only requests to private IPs through the VPC connector'.
I seem to be getting a 403 when attempting to hit the service. Has anyone had this issue? If so, how did you solve this problem?
You need to set the egress to All, to route all the traffic to the serverless VPC connector.
Indeed, even if you set the service B to internal egress, the Cloud Run service is still exposed publicly, but an additional check is performed on the requests that come in to validate the traffic origin (comes from your VPC or not).
In your case, in the service A, with the private range only egress, you route only the traffic going to private IP, and it's not the case of the always-publicly-exposed "internal" service B.
I am guessing that the code 403 you are getting it from the cloud run service and that is a problem with the authentication, so to solve that error code you could follow this link, there you will find a detail explanation of how authenticated users for you services.
I was able to fix this issue. This must be used when you have to use authenticated user to access cloud run application
Accessing Authenticated Cloud Run applications using IAP
It means that your client is not authorized to invoke this service.
You can address this by taking one of the following actions:
If the service is meant to be invocable by anyone, update its IAM settings to make the service public.
If the service is meant to be invocable only by certain identities, make sure that you invoke it

Google Cloud Platform Compute Engine
When I created the VM within the VPC network, I set up a static internal IP.
The firewall allowed the personal computer IP.
In this situation, the VM's SSH could not be reached.
Once logged in to the Google Cloud platform, metadata I generated using the keigen command to access the VM in a terminal in local environment.
e.g) ssh email ID#IP
Why can't I access that VM's SSH from the console on the Google Cloud platform?
Thank you for reading it. :)
If we read the following GCP documentation ... https://cloud.google.com/solutions/connecting-securely#external
we find the following statement:
When instances do not have external IP addresses (including VMs that are backends for HTTPS and SSL proxy load balancers) they can only be reached by other instances on the network, Identity-Aware Proxy's TCP forwarding feature, or by using managed VPN gateway.
The key phrase to me is that they can only be reached .... It would thus appear that you can only reach a VM without a public IP using the recipes described in the article. If it were me, I'd consider actually giving the machine a public IP address and then following the recipes described in the article to only allow access to the machine through secured means. Google is promoting a story it called Beyond Corp which basically summarizes down to trust nothing. Every attempt to access any resource will be validated on a request by request basis and don't assume that lack of network access is enough to secure a resource. Instead, consider the notion that the VM can be publicly reachable but only authorized requests should be satisfied.
On AWS, I know how to set up a web server with inbound rules allowing HTTP and HTTPS and a database security group that only connect to the web server. The issue is I need to create a front end to manage the databases without using Internet access - this will be internal only and precludes the use of a public IP / public DNS. Does anyone know how I would do this?
To further elaborate, some of our AWS accounts are for internal use only - we can log in to the console, use CygWin to SSH in, see what's there, etc. But these accounts are for development purposes, and in a large enterprise such as this one, these are not allowed an IGW. So - no inbound Internet access is allowed. How do I create an app (e.g., phpMyAdmin type) in which our manager can easily view and edit the data in the database given the restriction that this must be done without inbound Internet access?
Host your database on RDS inside a VPC and create a VPN connection between your client network and your VPC.
host your database on one EC2 and also upload your front end there. your database will be running on locally on EC2 and you can connect front end to database. where database will not have public DNS it will running locally you can access only using SSH and front end script.
you check this official documentation from aws : https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_VPC.WorkingWithRDSInstanceinaVPC.html
for frontend script you can use https://www.adminer.org/ which is one file database management system. one simple file is there using this make connection to locally running database on EC2
I know this issue has been already discussed before , Yet I feel my question is a bit different.
I'm trying to figure out how am I to enable access to the Kibana over the self manged AWS elastic search which I have in my AWS account .
Could be that what am I about to say here is inaccurate or complete nonsense .
I am pretty novice in the whole AWS VPC wise section and to ELK stuck.
Architecture:
Here is the "Architecture":
I have a VPC.
Within the VPC I have several sub nets.
Each server sends it's data to the elastic search using log stash which runs on the server itself. For simplicity lets assume I have a single server.
The elastic search https url which can be found in the Amazon console is resolved to an internal IP within the sub net that I have defined.
Resources:
I have found the following link which suggest to use one of two option:
https://aws.amazon.com/blogs/security/how-to-control-access-to-your-amazon-elasticsearch-service-domain/
Solutions:
Option 1: resource based policy
Either to allow resource based policy for elastic search by introducing condition which specify certain IP address.
This was discussed in the following thread but unfortunately did not work for me.
Proper access policy for Amazon Elastic Search Cluster
When I try to implement it in the Amazon console, Amazon notifies me that because I'm using Security group , I should resolve it by using security group.
Security group rules:
I tried to set a rule which allows my personal computer(Router) public IP to access Amazon elastic search ports or even opening all ports to my public IP.
But that didn't worked out.
I would be happy to get a more detailed explanation to why but I'm guessing that's because the elastic search has only internal IP and not public IP and because it is encapsulated within the VPC I am unable to access it from outside even if I define a rule for a public IP to access it.
Option 2: Using proxy
I'm decline to use this solution unless I have no other choice.
I'm guessing that if I set another server with public and internal IP within the same subnet and VPC as that of the elastic search , and use it as a proxy, I would be then be able to access this server from the outside by defining the same rules to the it's newly created security group . Like the article suggested.
Sources:
I found out of the box solution that some one already made for this issue using proxy server in the following link:
Using either executable or docker container.
https://github.com/abutaha/aws-es-proxy
Option 3: Other
Can you suggest other solution? Is it possible to use Amazon Load balancer or Amazon API gateway to accomplish this task?
I just need proof of concept not something which goes into production environment.
Bottom line:
I need to be able to aceess Kibana from browser in order to be able to search elastic search indexes.
Thanks a lot
The best way is with the just released Cognito authentication.
https://aws.amazon.com/about-aws/whats-new/2018/04/amazon-elasticsearch-service-simplifies-user-authentication-and-access-for-kibana-with-amazon-cognito/
This is a great way to authenticated A SINGLE USER. This is not a good way for the system you're building to access ElasticSearch.
I have an AWS Simple AD deployment. I need the ldap_url. I have seen it represented in various forms such as simply ldap://example.com and also ldap://aws-[some-mysterious-id].whatever.com and even in some AWS documentation they simply use the LAN IP of one of the instances, which I can't find anywhere in the AWS console since the EC2 console hides your Simple AD servers just like it does not show your RDS instances either.
When using ldapsearch to query against the value represented by "Directory name" in the AWS Console for Directory Services, the result is ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1), so it does not appear to be that either.
Go to the AWS Directory Service console https://console.aws.amazon.com/directoryservice/home
Select your directory.
Under DNS address will be two IP addresses.
Note that these addresses are private IP addresses in your VPC.
If you need public Internet access to your Simple AD server, then put an ELB -> HA Proxy -> Simple AD in front. Add Route53 to provide a DNS name.
