Meletis Belsis - Introduction to information security

The document discusses denial of service (DoS) and distributed denial of service (DDoS) attacks. It defines DoS and DDoS attacks, describes different types of DoS attacks like SYN flooding and Smurf attacks. It also explains how botnets and tools are used to launch DDoS attacks, and discusses some common DDoS countermeasures like detection, mitigation and traceback.

The document discusses various topics related to computer security and hacking. It covers types of computer crimes over the years from the 1980s to 2000s involving viruses, financial theft, and denial of service attacks. It also summarizes different hacking techniques such as spoofing, session hijacking, denial of service attacks, buffer overflows, password attacks, and ways to improve security including password hashing and network security.

Hackers attack websites and networks for various reasons such as financial gain, espionage, activism, or terrorism. Common attack methods include denial of service attacks to crash systems, spoofing identities to gain unauthorized access, hijacking sessions, exploiting software vulnerabilities like buffer overflows, and cracking passwords. To prevent attacks, network administrators must secure systems from intrusion, monitor for suspicious activity, and keep software updated by patching known vulnerabilities.

This document summarizes information about computer security and hacking. It discusses how the internet has grown rapidly while security has lagged behind, allowing legions of hackers to emerge. It covers various types of computer crimes throughout history from the 1980s to 2000. It also describes different modes of hacker attacks like spoofing, denial of service attacks, buffer overflows, password attacks, and others. The goal of the document is to provide an overview of the key issues around computer security and how hackers have threatened systems over time.

This Presentation is useful to study about Denial of Service Attack or DoS Attack. This Presentation is also useful to make PPT on this topic.

This document discusses denial of service (DoS) and distributed denial of service (DDoS) attacks. It defines DoS attacks as attempts to render a system unusable or slow it down for legitimate users by overloading its resources. DDoS attacks multiply the effectiveness of DoS by using multiple compromised computers to launch attacks simultaneously. Common DoS attack types like SYN floods, Smurf attacks, and ping of death are described. The rise of botnets, which are networks of compromised computers controlled remotely, enabled more powerful DDoS attacks. Mitigation strategies include load balancing, throttling traffic, and using honeypots to gather attacker information.

This document provides an overview of hacking, including definitions, a brief history, famous hackers, the hacker attitude, basic hacking skills, and common hacking methods and attacks. It defines hacking as intruding on someone else's information space for malicious purposes. It discusses port scanning and ICMP scanning techniques used to gather target system information. Common attacks mentioned include denial-of-service attacks, threats from sniffers and key loggers, trojan attacks, and IP spoofing. The document provides details on specific attacks like ping of death and smurf attacks. It also discusses tools used and countermeasures to protect against hacking.

The document discusses denial of service (DoS) and distributed denial of service (DDoS) attacks, as well as man-in-the-middle attacks. It defines DoS and DDoS, noting that a DDoS involves multiple hosts attacking at once. Common DoS attack types like penetration, eavesdropping, man-in-the-middle, and flooding are described. Symptoms of attacks and preventative measures are outlined. The document then explains how man-in-the-middle attacks work using techniques like ARP poisoning to intercept communications. Defenses against man-in-the-middle attacks through encryption and detection methods are also presented.

There are several categories of attackers, including hackers, crackers, script kiddies, spies, employees, and cyberterrorists. Common attacks include password guessing, which attempts to learn a user's password through various means, and denial of service attacks, which flood a server or device with requests to make it unavailable. Malicious software, or malware, consists of computer programs intentionally created to harm systems and includes viruses, worms, logic bombs, Trojan horses, and back doors.

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.

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 presentation is intended to increase awareness of Extension Agents to the threats of scams and malware on the Internet. In addition it covers some ways to stay protected from such threats.

Malaga is the administrative capital of the Costa del Sol, however, it has remained out of the mass tourism until the last decade. Coinciding with the obsolescence of the port facilities, the city has found an opportunity in cruise tourism, becoming the second largest Spanish destination in this sector. The main attractive of Malaga is being the birthplace of one of the most revolutionary painters, Pablo Picasso; developing a large program for museums and hotels openings, cultural events and urban projects over the last few years in order to create an atmosphere suitable for all visitors’ tastes. On the other hand, this process is also creating monofunctional sectors, gentrification and theming of the principal Historic Site areas. This implies to focus on restoration plans and on projecting an image according to the one that tourists expect to see. In this context, several civil organizations have been formed to denounce heritage losses, social marginality and identity simplification through collaborative works that join web 2.0, participative cartography and academic research. We present a selection of these works.
