A COMPARISON OF CONGESTION CONTROL VARIANTS OF TCP IN REACTIVE ROUTING PROTOC...ijcsit
A widely used TCP protocol is originally developed for wired networks. It has many variants to detect and
control congestion in the network. However, Congestion control in all TCP variants does not show similar
performance in MANET as in wired network because of the fault detection of congestion. In this paper, we
do a performance comparison between TCP variants NEW RENO, SACK and Vegas in AODV and DSR
reactive (On-Demand) routing protocols. Network traffic between nodes is provided by using File Transfer
Protocol (FTP) application. Multiple scenarios are created and the average values of each performance
parameter are used to evaluate the performance. The results show that TCP variants perform better in
terms of throughput and Packet drop with DSR routing protocol compared with AODV routing protocol.
TCP variants show a lower Jitter in AODV compared with DSR.

The concept of the spanning tree protocol was devised to address broadcast storming. The spanning tree algorithm itself is defined by the IEEE standard 802.1D and its later revisions.
The IEEE Standard 802.1 uses the term bridge to define the spanning tree operation, and uses terms such as Bridge Protocol Data Units and Root Bridge when defining spanning tree protocol functions.
When a bridge receives a frame, it reads the source and destination address fields. The bridge then enters the frame’s source address in its forwarding database. In doing this the bridge associates the frame’s source address with the network attached to the por t on which the frame was received. The bridge also reads the destination address and if it can find this address in its forwarding database, it forwards the frame to the appropriate port. If the bridge does not recognize the destination address, it forwards the frame out from all its por ts except for the one on which the frame was received, and then waits for a reply. This process is known as “flooding”. Similarly, packets with broadcast or multicast destination MAC addresses will be flooded by a bridge.
A significant problem arises where bridges connect via multiple paths. A frame that arrives with an unknown or broadcast/multicast destination address is flooded over all available paths. The arrival of these frames at another network via different paths and bridges produces major problems. The bridges find the same source MAC address arriving on
multiple different por ts, making it impossible to maintain a reliable forwarding database. As a result, increasing numbers of packets will be forwarded to multiple paths. This process is selfperpetuating and produces a condition known as a packet storm, where the increase of circulating frames can eventually overload the network.
This thesis presents a simulation based analysis of these protocols. We used the combination of EIGRP&IS-IS, RIP&IS-IS routing protocols on the Hybrid network in order to reveal the advantage of one over the other as well as the robustness of each protocol combination and how this is measured.

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.
