routers access control lists (ACLs) must be put in place to allow only traffic with a legitimate protocol and destination. Between the routers and the endpoint a firewall solution must be put in place. The firewall must be configured to allow only allowed protocols and port numbers to communicate with specific destinations. Between the firewall and endpoint a (D)DoS a detection tool (such as Arbor’s Prevail) must be put in place. This measure not only allows for quick detection of (D)DoS it also permits

Abstract The aim of the research was to study the 3G (third generation) wireless networks security threats. From the data gathered through observations and literature review‚ security threats that may be possible in 3G mobile networks were identified and the methods which may be used to minimize such security threats in networks were determined. Recommendations are given to minimize the security

it can also be used on mail servers‚ name servers‚ and any other type of computer system. Denial of service (DoS) attacks may be started from a single machine‚ but they typically use many computers to carry out an attack. Since most servers have firewalls and other security software installed‚ it is easy to lock out individual systems. Therefore‚ distributed denial of service (DDoS) attacks are often used to coordinate multiple systems in a simultaneous attack. A distributed denial of service attack

A firewall is a set of related programs‚ located at a network gateway server‚ that protects the resources of a private network from users from other networks. (The term also implies the security policy that is used with the programs.) An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling what outside resources its own users have access to. Basically‚ a firewall
