kandi X-RAY | tripwire Summary

tripwire is a C++ library typically used in Server, Runtime Evironment, Nodejs applications. tripwire has no bugs and it has low support. However tripwire has 2 vulnerabilities and it has a Non-SPDX License. You can download it from GitHub.

Tripwire allows node.js applications to termiante execution of scripts that block the node.js event loop. For example, you can break out from infinite loops like while(true). This functionality is useful if you are executing untrusted code within your node.js process. Tripwire contains a native extension of node.js and currently supports Windows, Mac, and Linux. I do take contributions.

QUESTION

Securing a localhost port for a Flask/Celery app running locally on 0.0.0.0 in Docker on MacOS

Asked 2020-Sep-12 at 19:14

My app has a Flask backend and an Angular/Electron frontend. The app runs locally on Mac Catalina. Flask, Celery and Redis are in separate docker containers, while the frontend is outside Docker. The Flask container is listening on port 0.0.0.0:5078. I've set CORS policy to allow messages from "127.0.0.1:4200" only, sent by the frontend. There's no need for internet connections. The backend containers will be launched by the frontend by emulating a terminal command. I'll install the app remotely on non-technical users' Catalina MacBooks.

Question: According to Docker might be exposing ports to the world, Beware of exposing ports in Docker and Docker not blocked by macOS firewall, this use of 0.0.0.0:5078 is a security threat. How can I resolve this threat, eg by block ing any external connections to this port?

Here's some python 3.8 code

A working solution is based on the David Maze and Matt's comments and on this question. These are the steps:

Open Docker for Mac, Preferences and Docker Engine. Add "ip": "127.0.0.1" to the json config file.
In the docker-compose, set ports to "127.0.0.1:5078:5078" for the web service.
Leave the Dockerfile and the python code as before: ie, the flask host is still 0.0.0.0

As I checked, messages from Electron's localhost 4201 went through. Also, running netstat -anvp tcp | awk 'NR<3 || /LISTEN/ shows that the insecure port 0.0.0.0.5078 is no longer exposed to the outside. `

I think the issue is the indent level where you are specifying the options for win_feature. The options should be indented under the win_feature module, as opposed to on the same level.

QUESTION

Why do two identical processes don't take the double CPU load

Asked 2017-Nov-28 at 05:56

I am using a Raspberry Pi 3 and basically stepped over a little tripwire.

I have a very big and complicated program that takes away a lot of memory and has a big CPU load. I thought it was normal that if I started the same process while the first one was still running, it would take the same amount of memory and especially double the CPU Load. I found out that it doesn't take away more memory and does not affect the CPU load.

To find out if this behavior came from my program, I wrote a tiny c++ program that has extremely high memory usage, here it is:

...

ANSWER

Answered 2017-Nov-28 at 05:56

Well, I found out that there is a "lock" that makes sure a process doesn't take away all memory and makes the CPU load go up to 100%. It seems that than more processes there are, than more CPU load is there, but not in a linear way.

Additionally, the code I wrote to look for the behaviour has only high memory usage, the 30% level came from the cout in the standard library . Multiple processes can use the command at the same time without increasing the CPU load, but it affects the speed of the printing.

When I found out that, I got suspicious about the programs speed. I used the analytics in my IDE for c++ to find out the duration of my original program, and indeed it was a bit more that two times slower.

That seems to be the solution I was looking for, but I think this is not really applicable to a large audience since the structure of the Raspberry Pi is very particular. I don't know how this works for other systems.

BTW: I could have guessed that there is a lock. I mean, if you start 10 processes that take away 15% of the CPU load max level, you would have 150% CPU usage. IMPOSSIBLE!
