Abstract: Social networking sites offer a straightforward way for people to have a simple social presence through web. They provide a virtual environment for people to share each and every activity, their interests, and their circle of acquaintance with their family, friends, or even the unknown. With so much sharing, hackers and thieves have found very easy ways to steal personal information through these networking sites. This calls for advances in security protocols to safeguard against hackers which form the basis of this research. In this paper, we will discuss some of the privacy and security concerns, attacks and their respective prevention techniques. In this paper we propose an architecture for secure request response exchange of data between users. This architecture improves the customization of profiles. Our research suggests that only a proper knowledge of the hacking strategies will prove the best defence in the war against cyber-attacks.
