Designing a Novel Two-Tier Authentication Algorithm for Web Service Architecture

Web pages are secured by one-tier security constraints based on username and password. This one-tier security module is the only way to protect the web pages from hackers. However, the one-tier security constraints on web service architecture have several flaws. It can be hacked from outside without notifying the authorised user. Further, hackers can easily obtain the username and password, which is entered on the web pages to login for further actions. When the system is connected to the internet, the system can be hacked to get the username and password that can be done by monitoring user’s keystroke from a remote location. Considering the credentials of one-tier security constraints are being hacked, this paper analyses these flaws and modelled two-tier security constraints to secure the web service. In the proposed architecture pattern, recognition mechanism is used to authenticate the user. The pattern recognition architecture displays at dynamic locations for each refresh of the web page, which prevents the proposed twotier architecture from being hacked as well as guessing attack

Cyber Security Concerns in Social Networking Service

Today’s world is unimaginable without online social networks. Nowadays, millions of people connect with their friends and families by sharing their personal information with the help of different forms of social media. Sometimes, individuals face different types of issues while maintaining the multimedia contents like, audios, videos, photos because it is difficult to maintain the security and privacy of these multimedia contents uploaded on a daily basis. In fact, sometimes personal or sensitive information could get viral if that leaks out even unintentionally. Any leaked out content can be shared and made a topic of popular talk all over the world within few seconds with the help of the social networking sites. In the setting of Internet of Things (IoT) that would connect millions of devices, such contents could be shared from anywhere anytime. Considering such a setting, in this work, we investigate the key security and privacy concerns faced by individuals who use different social networking sites differently for different reasons. We also discuss the current state-of-the-art defense mechanisms that can bring somewhat long-term solutions to tackling these threats
