Distributed Denial of Service (DDoS) is a type of attack using the volume, intensity, and more costs mitigation to increase in this era. Attackers used many zombie computers to exhaust the resources available to a network, application or service so that authorize users cannot gain access or the network service is down, and it is a great loss for Internet users in computer networks affected by DDoS attacks. In the Network Forensic, a crime that occurs in the system network services can be sued in the court and the attackers will be punished in accordance with law. This research has the goal to develop a new approach to detect DDoS attacks based on network traffic activity were statistically analyzed using Naive Bayes method. Data were taken from the training and testing of network traffic in a core router in Master of Information Technology Research Laboratory University of Ahmad Dahlan Yogyakarta. The new approach in detecting DDoS attacks is expected to be a relation with Intrusion Detection System (IDS) to predict the existence of DDoS attacks.
The Art of Cyber War [From Black Hat Brazil 2014]Radware
With cyber-attacks becoming a growing concern for organizations, availability-based attacks, also known as Denial of Service or Distributed Denial of Service attacks, have long moved from a form of cyber protest to a destructive weapon that is used by cyber criminals, hacktivists and even governments.
In 2013 we saw a growing use of a new type of attack where attackers used legitimate transactions to saturate application servers’ resources. In this presentation, Security Expert Werner Thalmeier demonstrates how such an advanced attack can be created from a laptop running in an anonymous public WiFi network. He also evaluates the attack landscape and its impact on organizations as well as shares the best practices to protect against such cyber-attacks.

DISTRIBUTED DENIAL OF SERVICE (DDOS) ATTACKS DETECTION MECHANISM ijcseit
Pushback is a mechanism for defending against Distributed Denial-of-Service (DDoS) attacks. DDoS
attacks are treated as a congestion-control problem, but because most such congestion is caused by
malicious hosts not obeying traditional end-to-end congestion control, the problem must be handled by the
routers. Functionality is added to each router to detect and preferentially drop packets that probably
belong to an attack. Upstream routers are also notified to drop such packets in order that the router’s
resources be used to route legitimate traffic hence term pushback. Client puzzles have been advocated as a
promising countermeasure to DoS attacks in the recent years. In order to identify the attackers, the victim
server issues a puzzle to the client that sent the traffic. When the client is able to solve the puzzle, it is
assumed to be authentic and the traffic from it is allowed into the server. If the victim suspects that the
puzzles are solved by most of the clients, it increases the complexity of the puzzles. This puzzle solving
technique allows the traversal of the attack traffic throughout the intermediate routers before reaching the
destination. In order to attain the advantages of both pushback and puzzle solving techniques, a hybrid
scheme called Router based Pushback technique, which involves both the techniques to solve the problem
of DDoS attacks is proposed. In this proposal, the puzzle solving mechanism is pushed back to the core
routers rather than having at the victim. The router based client puzzle mechanism checks the host system
whether it is legitimate or not by providing a puzzle to be solved by the suspected host.

CloudFlare DDoS attacks 101: what are they and how to protect your site?Cloudflare
Distributed denial of service (DDoS) attacks have scaled up in size and frequency over the past year. Attackers constantly adopt new methods to flood your website and network with malicious traffic. What exactly are DDoS attacks and how do they work? More importantly, how can you ensure that your website stays protected. CloudFlare solutions engineer Trey Guinn discusses the nature of DDoS attacks, with a focus on amplification attacks. He explains how CloudFlare is able to stop such attacks and also what can you do to ensure you are not part of the problem by running open NTP servers or DNS resolvers.
A ROBUST MECHANISM FOR DEFENDING DISTRIBUTED DENIAL OF SERVICE ATTACKS ON WEB...IJNSA Journal
Distributed Denial of Service (DDoS) attacks have emerged as a popular means of causing mass targeted service disruptions, often for extended periods of time. The relative ease and low costs of launching such attacks, supplemented by the current inadequate sate of any viable defense mechanism, have made them one of the top threats to the Internet community today. Since the increasing popularity of web-based applications has led to several critical services being provided over the Internet, it is imperative to monitor the network traffic so as to prevent malicious attackers from depleting the resources of the network and denying services to legitimate users. This paper first presents a brief discussion on some of the important types of DDoS attacks that currently exist and some existing mechanisms to combat these attacks. It then points out the major drawbacks of the currently existing defense mechanisms and proposes a new mechanism for protecting a web-server against a DDoS attack. In the proposed mechanism, incoming traffic to the server is continuously monitored and any abnormal rise in the inbound traffic is immediately detected. The detection algorithm is based on a statistical analysis of the inbound traffic on the server and a robust hypothesis testing framework. While the detection process is on, the sessions from the legitimate sources are not disrupted and the load on the server is restored to the normal level by blocking the traffic from the attacking sources. To cater to different scenarios, the detection algorithm has various modules with varying level of computational and memory overheads for
their execution. While the approximate modules are fast in detection and involve less overhead, they provide lower level of detection accuracy. The accurate modules employ complex detection logic and hence involve more overhead for their execution. However, they have very high detection accuracy. Simulations carried out on the proposed mechanism have produced results that demonstrate effectiveness of the proposed defense mechanism against DDoS attacks.

Conclusion
Understanding TCP Flood Attacks
TCP Flood Attacks are a form of cyber attack that aims to overwhelm and disrupt computer networks by exploiting vulnerabilities in the Transmission Control Protocol (TCP). As one of the fundamental protocols of the internet, TCP plays a crucial role in ensuring reliable and ordered data transmission between devices. However, malicious actors can manipulate the protocol to flood target systems with a high volume of TCP connection requests, leading to network congestion, service disruptions, and resource exhaustion.
What is a TCP Flood Attack?
To understand TCP Flood Attacks, it’s essential to grasp the basics of the TCP protocol. TCP operates as a connection-oriented protocol that provides reliable, error-checked data transmission across networks. It guarantees that data packets sent from one device reach the destination device in the correct order.
A TCP Flood Attack occurs when an attacker floods a target system with an overwhelming number of TCP connection requests. The attack is typically launched using botnets, which are networks of compromised devices controlled by the attacker. By initiating a large number of TCP connections simultaneously, the attacker aims to exhaust the target system’s resources and overload its capacity to handle legitimate network traffic.
How TCP Flood Attacks Work
TCP Flood Attacks follow a specific pattern to disrupt network communications.
Step 1: Reconnaissance: The attacker identifies potential target systems by scanning IP addresses or exploiting vulnerabilities in poorly secured devices.
Step 2: TCP Connection Initiation: The attacker uses a botnet to send a flood of TCP connection requests to the target system.
Step 3: Target System Response: The target system receives the TCP connection requests and allocates system resources to establish connections.
Step 4: Resource Exhaustion: As the number of connection requests overwhelms the target system’s capacity, resources such as memory, processing power, and network bandwidth become depleted.
Step 5: Service Disruption: The target system becomes unable to handle legitimate network traffic, resulting in network congestion, slowdowns, and potential service outages.
Types of TCP Flood Attacks
TCP Flood Attacks can manifest in different forms, each targeting specific aspects of the TCP protocol. Some common types of TCP Flood Attacks include:
SYN Flood Attacks
SYN Flood Atta
This is a presentation i made about Denial of Service or a Distributed Denial of Service (DoS / DDoS) and the latest methods used to crash anything online and the future of such attacks which can disrupt the whole internet . Such attacks which are in TB's and can be launched from just single computer. And, there is not much that can be done to prevent them.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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).

DDoS Network Attack Traits
† Common characteristics
¿ Exploits layer Layer 3-4 protocols
¿ Does not require a
full connection (often spoofed)
¿ High volume attacks can
overwhelm pipes and/or
connection capabilities
¿ Simple to create the
high volumes necessary
for such attacks
† Types
¿ Malformed requests
¿ Spoofing
¿ High PPS rates
¿ Connection exhaustion
14. 14
SYN Flood Attack
• The attacker or botnet sends multiple TCP SYN requests to the target
• Target responds to each SYN with a SYN-ACK to establish a valid connection, waits for ACKs
• Connection table of the server fills up with “half-opens”, new connections are dropped
• Server/service effectively “DDoSed” at that point, legitimate users shut out
• Why it works – Exploits the TCP 3-Way Handshake weakness (blind trust)
15. 15
DNS Amplification Attacks
• Valid UDP-based DNS requests using a spoofed IP address (similar to Smurf attack)
are sent to the intended target (victim)
• Type of attack executed against Spamhaus (300Gbps) in 2013
• Why it works: DNS is heavily used (Web, Email, VoIP) and generally unrestricted
Nature of DNS results in larger response volume than request volume
16. 16
† Common characteristics
¿ Legit TCP/UDP connections
(Not spoofed)
Thus harder to differentiate
¿ Operates at L7
(Protocol and packet payload)
¿ Exploits flaws in
or limitations of applications
¿ More efficient and lethal
¿ Sophisticated:
Evades simple countermeasures
† Types
¿ High host processing
¿ Application floods
¿ Application exploits
¿ Amplification attacks
DDoS Application Attack Traits
17. 17
HTTP GET Flood
• Huge flood of HTTP GET packets, requesting large amounts of data/objects from the target server
• Due to the amount of requests coming from botnets, the target system is overwhelmed
and cannot respond to legitimate requests from users
• Why it works: Since the 3-way TCP handshake has been completed, these requests look legitimate
18. 18
Slow POST/RUDY Attack
• A common attack, where attacker sends HTML “POSTs” at slow rates under the same session
Slow POST tool RUDY uses long-form field submissions to perform these attacks
• Causes server application threads to await the end of boundless POSTs in order to process them
• This results in exhaustion of web server resources and prevents service for legitimate traffic
19. 19
Slowloris Attack
• Slowloris holds many connections to the target web server open as possible, for as long as possible.
Creates connections to the target server, but sends only a partial request at a very slow rate.
• The targeted server keeps each of these false connections open, eventually overflowing the
maximum concurrent connection pool and shutting out legitimate clients.
20. 20
Network Time Protocol (NTP) Amplification Attack
• Attacker gains control of a server on a network that allows Source IP address spoofing
(i.e., it does not follow IETF BCP38 (Best Current Practices) for ingress filtering)
• Large number of spoofed UDP packets sent appearing to come from the intended target
• UDP packets are sent to NTP servers (port 123) that support the MONLIST command
• CloudFlare attacker used 4,529 NTP servers running on 1,298 different networks
Each server sent an average 87Mbps of traffic to CloudFlare = 400Gbps!
