Let's discuss about vpn's and tor security
Last week I was looking at Tor network security. I have learnt quite a new things that I didn't knew about earlier. So, I decide to summarize it and put it in a article.

Creating encrypted partition in linux
The risk of systems getting physically compromise, particularly portable systems such as laptops, puts sensitive data at risk of compromise. Encrypting its data mitigates the risk of getting exposure if system is lost.

Creating ARM architecture environment inside x86/x64 linux
If you want your hands on arm architecture assembly then you probably would be wondering how can I generate the *ARM* assembly or use ARM toolset in general inside my intel x86 or x64 architecture system. In this article we will explain you how you can do that by using qemu and chroot.

Reduce Security Risks with SELinux
Discover SELinux, a security module that provides extra protocols to ensure access control security. It supports mandatory access controls (MAC) and is an integral part of RHEL’s security policy.
Exploit Development
Exploiting Off-by-One buffer overflow vulnerability
Off-by-one vulnerability is little difficult to find and hence can be present in big softwares.It can cause due to not aware of fact if your string provided is not null terminating then strcpy will add a null terminator at the end of string,
Firmware
Replace your proprietary bios with linux firmware
Intel system comes with UEFI, UEFI is a proprietary and closed-source operating system that can be exploited.NERF (Non-Extensible Reduced Firmware), an open source software system developed at Google can replace almost all of UEFI firmware with a tiny Linux kernel and initramfs.
Containers
Demystifying Linux Containers(LXC)
Containers are the future when it comes to using and shipping applications. But Linux containers or LXC can be used for more than just that. This article covers the use of LXC on a daily basis as well as for production.

Finding and removing malware from windows in minimal steps using sysinternals suite
Did your system ever get affected with malwares? Did you know you can manually remove common malwares with very little technical knowledge. In this article I will explain you how to find malware using sysinternals suite.

Sandboxing and program isolation in linux using many approaches (Part 2)
Containers are tools for isolation which use namespaces to archive that.They are called light weight virtualization because they provide process level isolation only, means they depend on linux kernel.
Security
Sandboxing and program isolation in linux using many approaches (Part 1)
You can secure your linux system by isolating the malicious program or risky tasks using Sandboxing in different ways to stop it from affecting your main system.Sandboxing means providing a safe environment for a program or software so you can play around it without hurting your system
Virtualization
Data Storage virtualization in Linux (Part 2)
In the previous part we talked about how we can create sparse file storage and create file system to mount or share across network. Now we will look into some common disk operations that we can do with this storage like scaling, encryption etc.
Virtualization
Data Storage virtualization in Linux (Part 1)
Learn how to use file storage in Staas services. In file storage we create a file and use it as our virtual partition then format it in desire file system and mount it. All the operation we do in our real disk partition(/dev/sda*) can be done on that with some little tricks or manipulation.
