Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

A Linux file system is a hierarchical, tree-like structure that stores
and organizes files and directories on a computer.
In Linux, everything is a file, including devices, programs, and
system information.
The Linux file system tree is rooted at the root directory (/).
Several types of object exist in the filesystem.
-Normal Files :-Includes text files, graphics files, executable, etc.
-Directories :- Directories contain named 'links' to other files
-Device Files :- Devices (disks, tape drives , etc) are identified by device file.
-Symbolic Links:- References to files located at other points in the file system.
File names can be up to 255 characters long which are Case sensitive.
All characters except '/' are legal in filenames '/' is used as a separator in path
names.
Network File System are physically somewhere else, but appear as if they
are mounted on one computer.
18. Linux File System
Brief Description
/(root) :-The root filesystem is the top-level directory of the filesystem.
It must contain all of the files required to boot the Linux system before other
filesystems are mounted.
/bin :- The /bin directory contains user executable files.
/boot:- Contains the static bootloader and kernel executable and
configuration files required to boot a Linux computer.
/dev:- This directory contains the device files for every hardware device
attached to the system.
/etc : Contains the local system configuration files for the host 17
Computer.
/media:- A place to mount external removable media devices such as USB
thumb drives that may be connected to the host.
/mnt:- A temporary mountpoint for regular filesystems (as in not
removable media) that can be used while the administrator is
repairing or working on a filesystem.
19. Linux File System
Brief Description
/opt:- Optional files such as vendor supplied application programs
should be located here.
/sbin:- System binary files. These are executables used for system
Administration.
/tmp:- Temporary directory. Used by the operating system and many
programs to store temporary files.
/usr:- These are shareable, read-only files, including executable binaries
and libraries, man files, and other types of documentation.
/var:- Variable data files are stored here. This can include things like log
files, MySQL, and other database files, web server data files, email
inboxes, and much more.
