As the internet continues to grow‚ we may never be able to completely protect our privacy especially when it comes to shopping online and social networking sites. Abstract I chose this topic because it seems to always be in the news and there is also an interesting section about this topic in chapter three in the text. Whether it has to do with online shopping or social networking sites‚ it seems like once we make it on the internet‚ anyone can be located and can be at risk. Just Google anyone’s

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

open. This is done by limiting the number of TCP connections made at the entry and exit points of the network structures. (Kaeo‚ 2004) Recently there has been a variation of a DoS attack that has caused further problems. This is known as Distributed Denial of Service attack. How this is accomplished is a number of computers are used to launch a DoS attack. The thought is that these attacks come from the external internet. One of the best ways to mitigate this is to set up a firewall between the internet

There are many security attacks in MANET and DDoS (Distributed denial of service) is one of them. Our main aim is seeing the effect of DDoS in routing load‚ packet drop rate‚ end to end delay‚ i.e. maximizing due to attack on network. And with these parameters and many more also we build secure IDS to detect this kind
