I can't remember the last time I asked myself, 'What's up?'

But you know, I think the best question to ask yourself is, 'Hey, me, what's up?' Yes, you can see yourself with this question.

I don't have any ideas for writing, but may I can send a music from the past
When I was younger than i am now

Maybe you have a memory with it

A big question

How can you introduce yourself

Thinking about it.

Please send the final vote and let me use it to decide.

Introduction:

Why must we harden the Linux kernel?

Thinking about this question:

You have a big house with many valuables, and now you want to shield them from thieves. You must find ways to secure the house, such as using many IP cameras for detection and taking various measures to protect your valuables.

Now, let me ask another question:
Your phone is always with you.
OK, now imagine a hacker finds a bug in your phone and gains access to it. They can take photos, record voice, and access it completely, using your data. Now, think about what you would want to do after that.

Let me say:
Nothing Because now your data is for selling.


( this is just an introduction to start speaking about secure options in the linux kernel )

Thank you for sending votes.
And now the channel has a group.
With a 24-hours timer for automatic content deletion.

Welcome Everyone
Welcome where ? To new day 😁

OK let's Go

The First Option is about

DM_CRYPT

When should we enable it!?

Imaging now you want to install a new distribution and your first parameter is encryption and you want to use software encryption to encrypt your disk because you need use cryptoapi

Like cryptsetup software

OK now what !?
We must enable it

Yes just this

I wish have best times.

#persian_music
Persian version

Welcome everybody
Welcome to introducing a new parameter

CONFIG_MODULE_SIG.

Denoscription:

Thinking about this section,
You have too many modules, and you have a signature for every module.
You shouldn't allow anybody to add a new module because maybe it's not good software.

We can use it for signature verification.
#Kernel_hardening #linux #options

I really like writing
But I don't have free time 🥲
And you know I'm not as good as you
Please tell me if you have any suggestions for writing better.

Hello everyone
Happy new year
I wish you all the best times with your loved ones.
Be Happy good days are very near
And believe in yourself.

Hello everybody,

I'm back again after maybe two months. Okay,
let's go.

Today, I want to speak about a very fun experience

Let me share it.
My friend told me, "Hey, could you please change the code for this project?" (It was in Java.)

At first, I asked myself, "I've never had experience with Java, but it was a request from my friend, so I told him, Okay."

First off, I thought of many things:
Using attack injection, which means finding symbols/functions and changing them.
Figuring out how to access the codes.

I selected the second way.

I know that reaching the codes in Java is very simple, and I can read and change them very easily.

And again, I know why I must write in C++ 😁 And why I don't have a liking for any other language

And I found that there are many ways to use method obfuscation in your codes. And please always use them because nerds are always after your codes.

This was just a cool prank. Please don't let this post affect your decision-making.

Hi everybody
I want talk about YAMA

#YAMA #linux #embedded #hardening

YAMA is a LSM ( Linux sub module )

What's Yama:
Yama is a Linux Security Module that collects system-wide DAC security protections

How we can enable it:
This is selectable at build-time with CONFIG_SECURITY_YAMA

Options:
0 - classic ptrace permissions
1 - restricted ptrace
2 - admin-only attach
3 - no attach

First off, I thought I had mostly written everything about it.
But after a few seconds, I realized it's better to read from web pages and help them continue writing.
