kandi X-RAY | acl Summary
ACL is a role/resource based ACL that allows for easy definition of permissions by combining rules for specific roles, resources and privileges. Roles can inherit from earlier defined roles and resources can inherit from earlier defined resources. After the ACL is loaded with a permissions set, easy testing through the isAllowed method returns either a true or false value.

QUESTION
Im trying to create a multithreaded namedpipe server as outlined in the msdn sample here https://docs.microsoft.com/en-us/windows/win32/ipc/multithreaded-pipe-server but Im trying to restrict the namedpipe to access by adminstrators group members only.
The example works correctly when no SECURITY_ATTRIBUTES structure is specified but when an SA is specified the first call is successful, but following calls to CreateNamedPipe fail as long as the first pipe is listening or communicating with a client. The create call fails, usually with ACCESS_DENIED, but sometimes with error 1305 The revision level is unknown. When the first pipe closes due to client disconnecting the following call will be successful for the next createnamedpipe call but will in turn fail once that pipe has a client.
I have tried multiple values for the grfInheritance field with no avail. This is my first adventure into explicitly specifying SECURITY so forgive me if I have missed something obvious. Note that in the Function that calls createnamedpipe I create a new SA structure with each create attempt but I have also tried creating one and sharing it outside the create loop.
Relevant code follows:

In addition to the requested access rights, the DACL must allow the calling thread FILE_CREATE_PIPE_INSTANCE access to the named pipe.

I am adding a command to the redis code and when I run the unit test, I want to see the content of some of the data structures. I am running the test like this: ./runtest --single unit/acl. I have also added server log like this:
ANSWER
Answered 2021-Jun-13 at 00:45Be sure to execute make after modifying the source code.
You will not see serverLog() messages when you execute the test runner; they are from redis-server.
For test runs, redis-server logs are written to tests/tmp//stdout.
Development cycle:
- Edit source code
- Write tests
- Compile source code
make
- Run tests
./runtest(add your arguments)
- Inspect redis-server logs
less tests/tmp/*/stdout
- Delete test artifacts
rm -rf tests/tmp/*

Below is the code and the error that I'm getting while testing in Lambda. I'm a newbie in python & serverless. Please help. This is created for uploading the findings from the security hub to S3 for POC.
...ANSWER
Answered 2021-Jun-12 at 16:33When we use Lambda we need to write our code inside the lambda_handler method
"def lambda_handler(event, context):" .
As you mentioned you are using lambda to run this code then probably the below code should work for you.

QUESTION
I built a Varnish VMOD that defines an object, which is instantiated in vcl_init and is always kept in memory, and used in individual requests.
My configuration is split up in several VCL files, that get loaded from a "master" VCL depending on some request parameters.
The master VCL also instantiates the object in question, which I want to use in another VCL. The reason why I don't instantiate the object in the same VCL I use it in, is that I have another VCL that defines some ACL-restricted routes to update the object from a data source.
E.g. master.vcl:
ANSWER
Answered 2021-Jun-10 at 14:38You can't do this with objects directly as they are scoped by the VCL and can't "escape" it. As you've experienced, you need to load the labeled vcl first, so you also need to create the object in it.
But nothing prevents you from creating objects that reference a global variable so all objects have access to the same data.
Alternatively, you can use the Event function to use a PRIV_VCL (https://stackoverflow.com/a/60753085) also referencing a global pointer and avoid using objects completely. This is what is done here for example: https://github.com/varnish/varnish-modules/blob/master/src/vmod_vsthrottle.c#L345
QUESTION
I need some suggestions for best practicality, security and maintainability
The scenario is:
- We have a private VPC with some servers,
- We have users that can access server A and A only
- Some users can access A, and B.
- Other only B and so on.
They need to access to theses servers from home and office.
The current idea is having a multiuser OpenVPN server with IPTables blocking access to the servers that the user can't access
Is there another option using AWS tools (VPCs,Security Groups, ACLs, Load Balancers, or others)?
Or other solutions better than this one?
Draw of current arch:
- One boundary server that does the bridge from the open world to the Private VPC (With OpenVpn and IPTables)
- 5 servers inside the private VPC
- 10 Users with different levels of access
Thanks
...ANSWER
Answered 2021-Jun-08 at 05:19Use AWS IAM to manage user access and permissions.
For your scenario, you can create 3 groups: Server A, Server B, Server AB.
Then attach IAM policy to each group. The policies will restrict access to specific EC2 only.
Sample Policy that may work for you (via https://aws.amazon.com/premiumsupport/knowledge-center/restrict-ec2-iam/ )
