Problem outputting HTML table from Javascript

Asked 2022-Mar-01 at 03:34

I'm trying to bring in data from an external json file, and use it to generate a table. I'm running into a problem on line 52 'Uncaught TypeError: Cannot convert undefined or null to object at Function.keys' . When I comment out the first 2 async functions, use the sample data in the 'mountains' variable and reference 'mountains' instead of users the html table generates as expected. I think the problem has to do with my 2nd async function but I'm a newbie at a loss. Any help appreciated!

Since fetch is asynchronous, you need to process the data only once fetch receives it

Falco output aws instance metadata

Asked 2021-Nov-29 at 14:05

I run falco and falcosidekick with docker compose, without k8s.

I need to retrive aws instance metadata to falco rules output. I've found the jevt field class but I encountered an error on falco container start

ANSWER

Answered 2021-Nov-25 at 22:59

several things to know:

the syntax for jevt.value is jevt.value[/awsRegion] (no quotes)
these kind fields are for events in json format, it works for kubernetes audit logs but in your case where the rule is based on syscalls
falco will not query aws metadata either, you will not have this information in your output like this

Configurations for falco and falcosidekick must be in 2 different files, it means you also need to mount a volume in falcosidekick container. You can also use environment variables if you prefer (but it implies your slack webhook url will be in clear text in your docker-compose file).

The problem here is about pathing. FourthOrRungeKut.py is in a folder named Mathematical Functions. When you do from FourthOrRungeKut import RungeKutta as RK4 it looks for FourthOrRungeKut.py in the root of your project.

To fix the problem, you first need to rename Mathematical Functions so that it is a valid module name in python. This means that you cannot use spaces in the folder. If you rename the folder to math, then you can do

How to identify commands ran by Ansible on a remote host in Falco context?

Asked 2021-Mar-14 at 04:05

I would like to know if someone has an idea about how to identify commands ran by Ansible within a remote host.

To give you more context I'm gonna describe my workflow in-depth:

I have a scheduled job between 1 am to 6 am which runs a compliance Ansible playbook to ensure the production servers configuration are up to date and well configured, however, this playbook change some files inside the /etc folder.
Besides this, I have a Falco stack which keeps an eye on what is going on the production servers and raises alerts when an event that I describe as suspicious is found (It can be a syscall/ network connection/ sensitive file editing "/etc/passwd, pam.conf, ..." etc...

So the problem I'm running through is, my playbook triggers some alerts for example:

ANSWER

Answered 2021-Mar-14 at 04:05

Ansible is python tool, so the process accessing the file will be python3. The commands that Ansible executes are based on the steps that are in the playbook.

You can solve your problem by modifying the falco rules. You can evaluating the proc.pcmdline in falcon rule and the chain of the proc.aname to identify that the command was executed by the ansible process (ex. process is python3, parent is sh grandparent is sudo, etc.)

If you need something for compilation, it needs to be a Maven dependency.

So take that artifact, install it in your local repository and add it as dependency.

Then your compilation process will probably work.

Note that using a dependency does not mean that you have to include the dependency into the resulting jar.

By default, Docker uses a json-file driver, which writes JSON-formatted logs to a container-specific file on the host where the container is running. Refer this docker logging

Giving -t option assigns pseudo tty through which main process of docker outputs logs to the virtual terminal. And aws log-driver looks for tty to capture logs. Look at this how -t option works and specifically answer number 3 in this post.
