Join Kevin Skoglund for an in-depth discussion in this video Denial of service, part of Foundations of Programming: Web Security.
- In this movie, we'll talk about…a particularly nasty attack called Denial of Service.…Denial of Service, or DoS for short,…is an attempt to make a server unavailable to users.…It's like knocking a website off the internet.…It's usually performed by overloading a server…with too many requests but it can also include…DNS or routing disruption so that people can't get…to the website or it can be performed…by using up disk space, processing power or bandwidth.…Basically anything that would allow a website…to not be available anymore would be considered…a Denial of Service attack.…
These attacks are often performed…by a distributed network of computers.…When they are we call it a "DDoS"…for distributed Denial of Service.…If you remember back in earlier movies…we talked about the botnets that are out there,…the zombie computers that can be called…to someone's bidding.…Well those computers can be tasked…with creating a Denial of Service situation for someone.…A Denial of Service attack is cheap to launch…and difficult to prevent.…
