Critical Thinking : DoS Attacks Denial of service (DoS) attacks can cripple an organization that relies heavily on its web application servers, such as online retailers. What are some of the most widely publicized DoS attacks that have occurred recently? Who was the target? How many DoS attacks occur on a regular basis? What are some ways in which DoS attacks can be prevented? Write a one-page paper on your research. Recently, DDoS attacks have become increasingly creative and outrageous. Japan was on the headlines in March of this year when over 50,000 video cameras were infected with Linux malware and the Mirai botnet. This conglomerate was used to attack various computers and systems around the world. Meanwhile, the Russian Defense Ministry said a total of 7 DDoS attacks were carried out against its website during the final vote on the names of new types of weaponry. The attacks originated from the territory of Ukraine, as well as countries in Western Europe and North America. Also, Americas Cardroom, which claims to be home to over one million online hands of poker each day, says that an unknown party has been attacking its site as well. The games have been paused or shutdown and the website has been on and off line multiple times as the attack has continued intermittently. The intensity of attacks also continues to grow. The most lucrative targets for cybercriminals seem to be cryptocurrencies, but it can be expected to see high-profile attacks against e-sports tournaments as well as relatively small ransoms targeting individual streamers and players. DDoS attacks occur everyday at various intensities and against various systems. A separate study by DDoS mitigation outfit Imperva Incapsula reported that more advanced application layer DDoS attacks are becoming more commonplace. The number of attacks in Q4 reached an all-time high, with an average of 889 application layer assaults per week. One such attack lasted for more than 47 days. At the same time packet flood network flood attacks are increasing in volume. Organizations can help prevent their computers from becoming part of a botnet by installing anti-malware software, using firewalls, keeping software up-to-date and forcing users to use strong passwords. Of all the ways to prevent DDoS attacks, the most basic step you can take to make your infrastructure "DDoS resistant" is to ensure that you have enough bandwidth to handle spikes in traffic that may be caused by malicious activity. In addition, network monitoring software can be helpful in determining when a system has become part of a botnet. Also, you should always change the default passwords for any IoT devices you install.
