Firewalls are hardware or software solutions that enforce security policies and protect networks. They work by regulating inbound and outbound network traffic through configured rules. A firewall typically has two network interfaces - one for the internal network and one for the external network. Traffic is checked according to port numbers, protocols, IP addresses, and other criteria before being allowed to pass through. Firewalls can protect both home and enterprise networks from threats by blocking unauthorized access and malware while allowing legitimate communications. They perform functions like network address translation, virus scanning, and application controls to secure network integrity.

Presentation by Charl van der Walt at INFO SEC Africa 2001.
The presentation begins with a case study of a DoS attack launched on a number of high profile sites by the canadian teen "Mafiaboy". An explanation of DoS and DDoS given. The impact of DDoS in South Africa is also discussed. The presentation ends with a series of discussions on DDoS countermeasures.
This document summarizes a survey of distributed denial-of-service (DDoS) attacks based on vulnerabilities in the TCP/IP protocol stack. It begins by introducing DDoS attacks and their architecture, then classifies DDoS attacks according to the TCP/IP layer they target - application layer, transport layer, or internet layer. Specific attack types are described for each layer, including HTTP flooding, SYN flooding, Smurf attacks, and more. The document aims to provide understanding of existing DDoS attack tools, methods, and defense mechanisms.
A denial-of-service attack (DoS attack) or distributed denial-of-service attack (DDoS attack) is an attempt to make a computer resource unavailable to its intended users. Although the means to carry out, motives for, and targets of a DoS attack may vary, it generally consists of the concerted efforts of a person or people to prevent an Internet site or service from functioning efficiently or at all, temporarily or indefinitely. Perpetrators of DoS attacks typically target sites or services hosted on high-profile web servers such as banks, credit card payment gateways, and even root name servers. The term is generally used with regards to computer networks, but is not limited to this field, for example, it is also used in reference to CPU resource management. There are two general forms of Dos attacks: those that crash services and those that flood services.
One common method of attack involves saturating the target machine with external communications requests, such that it cannot respond to legitimate traffic, or responds so slowly as to be rendered effectively unavailable. In general terms, DoS attacks are implemented by either forcing the targeted computer to reset, or consuming its resources so that it can no longer provide its intended service or obstructing the communication media between the intended users and the victim so that they can no longer communicate adequately.
This document is a project report submitted by two students, Ameya Vashishth and Amir Khan, for their Bachelor of Technology degree. It examines denial of service (DoS) attacks in cloud computing. The report includes an introduction to DoS attacks, descriptions of different types of attacks like ping of death, SYN flooding, and Smurf attacks. It also discusses tools used for DoS attacks, countermeasures, and the legal issues surrounding these attacks. The document contains abstract, table of contents, list of figures, and 10 chapters covering these topics in detail with examples.

DoS (Denial of Service) Attack Tutorial: Ping of Death, DDOS
What is DoS Attack?
DOS is an attack used to deny legitimate users access to a resource such as accessing a website, network, emails, etc. or making it extremely slow. DoS is the acronym for Denial of Service. This type of attack is usually implemented by hitting the target resource such as a web server with too many requests at the same time. This results in the server failing to respond to all the requests. The effect of this can either be crashing the servers or slowing them down.
Cutting off some business from the internet can lead to significant loss of business or money. The internet and computer networks power a lot of businesses. Some organizations such as payment gateways, e-commerce sites entirely depend on the internet to do business.
In this tutorial, we will introduce you to what denial of service attack is, how it is performed and how you can protect against such attacks.
Topics covered in this tutorial
· Types of Dos Attacks
· How DoS attacks work
· DoS attack tools
· DoS Protection: Prevent an attack
· Hacking Activity: Ping of Death
· Hacking Activity: Launch a DOS attack
Types of Dos Attacks
There are two types of Dos attacks namely;
· DoS– this type of attack is performed by a single host
· Distributed DoS– this type of attack is performed by a number of compromised machines that all target the same victim. It floods the network with data packets.
How DoS attacks work
Let’s look at how DoS attacks are performed and the techniques used. We will look at five common types of attacks.
Ping of Death
The ping command is usually used to test the availability of a network resource. It works by sending small data packets to the network resource. The ping of death takes advantage of this and sends data packets above the maximum limit (65,536 bytes) that TCP/IP allows. TCP/IP fragmentation breaks the packets into small chunks that are sent to the server. Since the sent data packages are larger than what the server can handle, the server can freeze, reboot, or crash.
Smurf
This type of attack uses large amounts of Internet Control Message Protocol (ICMP) ping traffic target at an Internet Broadcast Address. The reply IP address is spoofed to that of the intended victim. All the replies are sent to the victim instead of the IP used for the pings. Since a single Internet Broadcast Address can support a maximum of 255 hosts, a smurf attack amplifies a single ping 255 times. The effect of this is slowing down the network to a point where it is impossible to use it.
Buffer overflow
A buffer is a temporal storage location in RAM that is used to hold data so that the CPU can manipulate it before writing it back to the disc. Buffers have a size limit. This type of attack loads the buffer with more data that it can hold. This causes the buffer to overflow and corrupt the data it holds. An example of a buffer overflow is sending emails with file names that have 256 characters ...

DDoS attacks work by using botnets to overwhelm a target site with large amounts of traffic, making it unavailable to legitimate users. They can have major business impacts by disrupting systems, damaging resources, and costing companies millions per day of downtime. While prevention is challenging due to distributed nature of attacks and internet, companies can mitigate risks by having adequate bandwidth, deploying DDoS defense systems, monitoring traffic, and creating incident response plans.
Session for InfoSecGirls - New age threat management vol 1InfoSec Girls
This document discusses denial of service (DoS) and distributed denial of service (DDoS) attacks. It defines DoS and DDoS, describes common types like volumetric and application layer attacks. It also outlines tools used to carry out DDoS attacks and methods to protect against attacks, including configuring web servers and reverse proxies, using firewalls, and techniques from web application security firms.
The document discusses different types of denial of service (DoS) attacks, including distributed denial of service (DDoS) attacks. In a DoS attack, attackers flood a victim system with non-legitimate traffic to overload its resources and prevent authorized users from accessing it. A DDoS attack involves using compromised systems like bots in a botnet to launch a coordinated DoS attack from multiple sources against a single target. Specific attack types covered include SYN floods, which exploit the TCP three-way handshake process to fill a target's listen queue, and "phlashing" attacks, which can cause irreversible hardware damage.
This document provides an overview of distributed denial of service (DDoS) attacks. It discusses the components and architecture of DDoS attacks and classifies them into four categories: flood attacks, amplification attacks, TCP SYN attacks, and malformed packet attacks. Specific attack types like UDP floods, ICMP floods, Smurf attacks and Fraggle attacks are described. The document also covers DDoS defense problems and classifications such as intrusion prevention, detection, tolerance and response. It concludes that DDoS attacks are difficult to prevent due to readily available tools and the ability to target any internet host, and that the best defense involves vigilant system administration.

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.
