In a Denial-of-Service (DoS) attack, a malicious client (the attacker) performs operations designed to partially or completely prevent legitimate clients from gaining service from a server (the victim). (Brustoloni, N.D.) To defend your system from DoS attacks it typically involves the use of a combination of attack detection software, aiming to block traffic that is identified as illegitimate and allow all traffic that is identified as legitimate. Some traffic classification and response tools are Firewalls, Switches, Routers, Application front end hardware, IPS based prevention, DDS based …show more content…
defense, Blackholing and sinkholing, and Clean pipes.
The security tool I have chosen is Firewalls.
Firewalls are hardware or software-based network security system that controls the outgoing and incoming network traffic by analyzing the data packets and determining whether they should be allowed through or not based upon the settings. A firewall establishes a barrier between a trusted, secure internal network and another network that is not assumed to be secure and trusted. Many computers and other hardware such as routers and modems have built-in firewall capabilities. These firewalls can be effective with little or no configuration. Software firewalls can be installed on your computer and can be configured according to your needs. Many software firewalls have user defined controls for setting up safe file and printer sharing and to block unsafe applications from running on your computer. Software firewalls may also incorporate privacy controls and web content
filtering.
Always use a firewall, as well as anti-virus and anti-spyware software. The more lines of defense you have in place, the harder it is for hackers to get in. A correctly configured firewall will prompt you when it detects an unauthorized computer or program trying to access your computer or a software program is installed on your computer that tries to make an unauthorized outside connection. Many personal computer operating systems include software-based firewalls to protect against threats from the public Internet. Many routers that pass data between networks contain firewall components and, conversely, many firewalls can perform basic routing functions. There is a wide range of firewall software available that provides a good level of protection. Some software is available as 'freeware ', i.e. at no cost to home users, although some of these may have fewer functions.
In conclusion, the use of a Firewall will help to prevent a Denial-of-Service (DoS) attack on your system whether it is a business or home networking unit. A Firewall alone will not prevent all attacks but, it is a major component needed in all Operating systems. Although most Operating systems have a built in Firewall it never hurts to do some further research to see if there is a better version available.
