LetвЂ™s start by defining a simple denial of service or DoS attack. What is a DDoS attack and what does it consist of? According to The Guardian, this attack was the most massive of its kind in history. On October 21, 2016, one of the most severe massive DDoS attacks in the world took place, disrupting the services of large companies such as PayPal, Spotify, Twitter and Netflix. This technique dates back to the early 2000s, but according to Akamai reports, DDoS attacks have been on the rise since 2014. One of the most traditional cyber-attacks is carried out using the DDoS method. Each enterprise will need to balance these risks and benefits,Д«ut not all of the details of those decisions are covered here.As technological solutions emerge, new methods of computer warfare also appear that threaten the security of our platforms. There are pros and cons to locking accounts, to customers being able toД¬hoose their own account names, to using systems such as CAPTCHA, and security balance that must be reachedД«ased on the specific circumstances surrounding a given application. This defense mechanismД¬an be turned into a DoS attack against an application if there is a way The system until their account has been unlocked. Were to provide their valid password, they would be unable to login to This means that even if a legitimate user User passwords is to lock an account from use after between three toДЇive failed attempts to login. A common defense to prevent brute-force discovery of The first DoS case to consider involves the authentication system of the Login, as a user can launch the attack without the need of an account. This problem is exacerbated if session data is also tracked prior to a Storing too much information in the session, such as large quantities ofДata retrieved from the database, can cause denial of service issues. DoS Storing too Much Data in SessionД¬are must be taken not to store too much data in a user session object. User input is not adequately checked for its length, making this kind ofДЄttack possible. Reality is that in a web based application there may be places where the While this example above is an extremely simple case, the Into an array of 10 elements only, overwriting adjacent memory The reason is that strcpy would try to copy 53 characters

If this code example were executed, it would cause a segmentation faultДЄnd dump core. Public class MyServlet extends ActionServlet The following is a simple example of vulnerable code in Java: Possibly filling its whole available memory and corrupting its Is an extremely large number, it can cause serious issues on the server, The server mayД«egin to allocate the required number of objects specified, but if this To cause the environment to run out of available memory. Server does not enforce a hard upper limit on that value, it is possible How many of an object to create on the application server, and if the If users can supply, directly or indirectly, a value that will specify The following DoS techniques and examples were extracted from OWASP Other risk factors may also exist depending on the specific environment. Organization should avoid taking action that can make them a target of aДoS attack unless the benefits of doing so outweigh the potential costs The second example and perhaps the largest risk factor is not technicalДЄnd is in the domain of public relations or strategic communications.

This risk reduces the difficulty of successfully executing aДoS attack and can, left unchecked, result in DoS symptoms absent an The first example of a risk factor, inadequate resources, requiresДЄttention if system architecture was not designed to meet traffic demand Sources of risk include inadequate resources and non-technical threat Risk factors can break down into multiple categories. Interruptions, resulting in direct impact on availability. TheseДЄttacks introduce large response delays, excessive losses, and service Denial-of-service attacks significantlyДegrade the service quality experienced by legitimate users. Performing a DoS attack in order to access critical information orД®xecute commands on the server. Sometimes the attacker can inject and execute arbitrary code while

Vulnerability is exploited, or the way the service handles resources it In the same way, a service may stop if a programming Large number of requests, it may cease to be available to legitimate There are many ways to make a service unavailable for legitimate usersД«y manipulating network packets, programming, logical, or resources (site, application, server) unavailable for the purpose it was designed. The Denial of Service (DoS) attack is focused on making a resource Contributor(s): KristenS, Adar Weidman, psiinon, Adrew Smith, Jkurucar, kingthorin
