ImageSubXSS: an image substitute technique to prevent Cross-Site Scripting at...IJECEIAES
Cross-Site Scripting (XSS) is one of serious web application attack. Web applications are involved in every activity of human life. JavaScript plays a major role in these web applications. In XSS attacks hacker inject malicious JavaScript into a trusted web application, execution of that malicious script may steal sensitive information from the user. Previous solutions to prevent XSS attacks require a lot of effort to integrate into existing web applications, some solutions works at client-side and some solutions works based on filter list which needs to be updated regularly. In this paper, we propose an Image Substitute technique (ImageSubXSS) to prevent Cross-Site Scripting attacks which works at the server-side. The proposed solution is implemented and evaluated on a number of XSS attacks. With a single line, developers can integrate ImageSubXSS into their applications and the proposed solution is able to prevent XSS attacks effectively.

SURVEY ON KEY AGGREGATE CRYPTOSYSTEM FOR SCALABLE DATA SHARINGEditor IJMTER
Public-key cryptosystems produce constant-size cipher texts with efficient delegation
of decryption rights for any set of cipher texts. One can aggregate any set of secret keys and make
them as compact as a single key. The secret key holder can release a constant-size aggregate key for
flexible choices of cipher text set in cloud storage. In KAC, users encrypt a message not only under a
public-key, but also under an identifier of cipher text called class. That means the cipher texts are
further categorized into different classes. The key owner holds a master-secret called master-secret
key, which can be used to extract secret keys for different classes. More importantly, the extracted
key have can be an aggregate key which is as compact as a secret key for a single class, but
aggregates the power of many such keys, i.e., the decryption power for any subset of cipher text
classes. The key aggregate cryptosystem is enhanced with boundary less cipher text classes. The
system is improved with device independent key distribution mechanism. The key distribution
process is enhanced with security features to protect key leakage. The key parameter transmission
process is integrated with the cipher text download process.
FRONT END AND BACK END DATABASE SECURITY IN THREE TIER WEB APPLICATIONijiert bestjournal
This document discusses security techniques for front-end and back-end databases in three-tier web applications. It proposes a double security system that assigns each user session to a dedicated container or virtual computing environment. This allows the system to map and profile activity between the web server and database server, enabling it to detect attacks. The system separates traffic by session, analyzes HTTP requests and SQL queries, maps requests to queries, and can detect direct database attacks or SQL injection attacks by checking for unmapped queries.
I hope this helpes you to know more about what is SQL-injection and SYN attack and SYN foolds this present with there description also how to prvent this attacks.
A Novel Mutual Authentication Algorithm using Visual Cryptography with Novel ...IRJET Journal
The document proposes a novel mutual authentication algorithm using visual cryptography. It aims to provide stronger authentication security compared to traditional text-based passwords. The algorithm uses two registered images per user - a security image and password image. During registration, the server generates shares of the images and mails one share to the user. During login, the user uploads their share to authenticate the server, while the server generates a random session share of the password image to authenticate the user by reconstructing and hashing the image. The algorithm provides mutual authentication without third party involvement by using visual cryptography techniques on user-registered images.
Penetration testing is a field which has experienced rapid growth over the yearsGregory Hanis
Sockstress is a denial of service attack that consumes server resources by opening many TCP connections. It was introduced in 2008 and targets vulnerabilities in how TCP handles connections. While tools exist to detect and prevent Sockstress, it remains a potential threat. The attack can be performed by one machine or multiple zombies to mask the source. Defenses include limiting connections per IP and dropping those with zero window responses. Monitoring server resources like RAM usage can also help detect Sockstress attacks. Penetration testing is needed to identify vulnerabilities like this and prove due diligence for organizations.
Cloud Breach - Forensics Audit Planning
The goal of this presentation is to assist IT Risk and Security professionals with adding Cloud computing forensics to their Incident Response team.
It should assist them with understanding the technical ways of capturing forensic data from cloud service providers using security controls that incorporate and integrate logging, chain of evidence, virtualization and cloud security architecture
This document describes a system called Web Gate Keeper that provides intrusion prevention for multi-tier web applications. Web Gate Keeper tracks user sessions and controls access across the web server and database server tiers to prevent various types of attacks. It uses container virtualization to isolate each user's session. This prevents attacks like privilege escalation, session hijacking, SQL injection, cross-site scripting, and direct database attacks. The system architecture involves processing all requests through a servlet filter for session validation before dispatching to the application. It detects intrusions and notifies administrators.
Security Risk Assessment for Quality Web DesignTing Yin
This document provides a security risk assessment for Quality Web Design (QWD) and recommends solutions. It identifies three main security vulnerabilities: 1) issues with the network infrastructure hardware, 2) the risk of SQL injection attacks targeting client web pages, and 3) threats against the existing VPN like intrusion and denial of service attacks. It analyzes the level of risk for each threat and their potential consequences, such as theft of information, website downtime, and data or system manipulation. To address these risks, the document recommends that QWD replace its current IPSec VPN with Dell SonicWall NSA 250m and NSA 6600 appliances to gain improved security protections, services, and remote access capabilities. This would help mitigate threats while also
PRIVACY-PRESERVING PUBLIC AUDITING FOR DATA STORAGESECURITY IN CLOUD COMPUTINGKayalvizhi Selvaraj
This document proposes a privacy-preserving public auditing system for cloud data storage. It allows an external third party auditor (TPA) to audit user's outsourced data stored in the cloud without learning the data content. The proposed scheme supports batch auditing where the TPA can perform multiple auditing tasks simultaneously. It utilizes public key based homomorphic authenticators and random masking techniques to achieve privacy-preserving public auditing for cloud data storage.
Preventing Web-Proxy Based DDoS using Request Sequence Frequency IOSR Journals
This document discusses preventing distributed denial of service (DDoS) attacks that use web proxies. It proposes detecting abnormal request sequences from web proxies by analyzing the frequency of request sequences and comparing it to a web proxy's historical behavioral profile. When abnormal sequences are detected, a "soft-control" approach is used to reshape suspicious sequences rather than rejecting the entire sequence, to avoid impacting legitimate users. A hidden semi-Markov model is used to model the temporal and spatial behavior of web proxy traffic over time. This allows both fine-grained and coarse-grained detection of attacks at the server level, independently of traffic intensity or changing web content.
Cryptographic Countermeasure Against Prevention Of Dos and Distributed DOS A...IRJET Journal
The document discusses cryptographic puzzles as a countermeasure against denial of service (DoS) and distributed denial of service (DDoS) attacks. It proposes a system called a software puzzle that generates puzzles for clients to solve in order to access server resources. When under attack, the server would generate and send puzzles to clients, and only grant access to clients that correctly solve the puzzles, thereby preventing attackers from overwhelming the server. However, existing puzzle schemes are not effective against attacks that use GPUs to rapidly solve puzzles in parallel. The document proposes improvements to puzzle generation and verification that aim to make the puzzles more difficult to solve by attackers using GPUs or multiple computers.
IRJET - Providing High Securtiy for Encrypted Data in CloudIRJET Journal
This document proposes a scheme for providing high security for encrypted data stored in the cloud. It outlines a secure, easily integrated, and fine-grained mechanism for verifying query results over encrypted cloud data. The scheme allows an authorized user to verify the correctness of each file in a query result set, as well as detect if any qualified files were not returned. It constructs verification objects for outsourced encrypted files that can be used to verify results. Trapdoor, decryption, and verification keys are generated to control access and detect unauthorized access attempts. The scheme guarantees the authenticity of verification objects and ensures the cloud server learns nothing about requested objects.

Appraisal of the Most Prominent Attacks due to Vulnerabilities in Cloud Compu...Salam Shah
Cloud computing has attracted users due to high speed and bandwidth of the internet. The e-commerce systems are best utilizing the cloud computing. The cloud can be accessed by a password and username and is completely dependent upon the internet. The threats to confidentiality, integrity, authentication and other vulnerabilities that are associated with the internet are also associated with cloud. The internet and cloud can be secured from threats by ensuring proper security and authorization. The channel between user and cloud server must be secured with a proper authorization mechanism. The research has been carried out and different models have been proposed by the authors to ensure the security of clouds.

This document summarizes a research paper that proposes a model for centralized user authentication as a service for cloud networks. The paper reviews security issues and traditional authentication approaches in cloud computing. It then presents a model that implements user authentication through a cloud gateway and authentication server rather than direct access to resources. The model is intended to provide secure authentication while maintaining availability of cloud services. The paper also describes implementing a prototype of the proposed model using VMware Workstation to create a virtual cloud environment with different operating systems.
Implementation of user authentication as a service for cloud networkSalam Shah
There are so many security risks for the users of cloud computing, but still the organizations are switching towards the cloud. The cloud provides data protection and a huge amount of memory usage remotely or virtually. The organization has not adopted the cloud computing completely due to some security issues. The research in cloud computing has more focus on privacy and security in the new categorization attack surface. User authentication is the additional overhead for the companies besides the management of availability of cloud services. This paper is based on the proposed model to provide central authentication technique so that secured access of resources can be provided to users instead of adopting some unordered user authentication techniques. The model is also implemented as a prototype.

SVAC Firewall Restriction with Security in Cloud over Virtual EnvironmentIJTET Journal
Abstract— Cloud computing is so named for the reason that the information being accessed is found in the "clouds", it
does not entail a user to be in a precise place. Organizations found that cloud computing allows them to diminish the cost
of information management, in view of the fact that they are not obligatory to own their own servers. They can use
capacity leased from third parties. It is more important to store and to secure the data in the cloud. It plays a vital role in
the cloud. The data that can be secured by implementing SVAC (Security Virtualization Architecture for Cloud) Firewall
in the virtual environment. An effectual firewall security has been implemented for jamming and filtering the superfluous
requests coming from the clients prior to the request move towards the virtual machine. Next step is to secure the users.
During the demand dispensation, if the abuser requests the sophisticated of information from the cloud, then based on the
compensation prepared by the cloud client, they can access the data from the cloud server. This paper shows the
architecture and the unwanted request can be restricted through SVAC firewall also how the high level of data that can be
accessed by the highly authorized user.
The Ultimate Guide for Cloud Penetration Testing. Cloud penetration testing is an artificial attack that is launched by a known ethical hacker in the disguise of a potential hacker just to check the number of vulnerabilities, threats, and loopholes in a particular cloud provider that can sincerely pass on any backdoor access to the real-time hackers and weaken the security posture of the organization.

Impact of Flash Crowd Attack in Online Retail ApplicationsIJEACS
This document discusses flash crowd attacks on online retail applications. It begins by introducing denial of service (DoS) and distributed denial of service (DDoS) attacks. It then explains that flash crowd attacks are a type of DDoS attack that aims to overwhelm servers with legitimate-looking requests. The document outlines the network model used to simulate flash crowd attacks and presents results analyzing the impact on server energy levels. It finds that as the number of requests increases, servers experience decreased energy and lifetime. The study aims to minimize these attacks by having servers identify real clients to prioritize sending responses.
Survey of uncertainty handling in cloud service discovery and compositionijngnjournal
With the spread of services related to cloud environment, it is tiresome and time consuming for users to look for the appropriate service that meet with their needs. Therefore, finding a valid and reliable service is essential. However, in case a single cloud service cannot fulfil every user requirements, a composition of cloud services is needed. In addition, the need to treat uncertainty in cloud service discovery and composition induces a lot of concerns in order to minimize the risk. Risk includes some sort of either loss or damage which is possible to be received by a target (i.e., the environment, cloud providers or customers). In this paper, we will focus on the uncertainty application for cloud service discovery and composition. A set of existing approaches in literature are reviewed and categorized according to the risk modeling

1) Cloud computing allows on-demand access to computing resources over the internet. However, this architecture is vulnerable to security attacks like zombie attacks.
2) A zombie attack occurs when an unauthorized user takes control of a virtual machine and uses it to launch denial-of-service attacks by sending useless traffic. This degrades network performance.
3) The paper proposes a technique for detecting malicious users and isolating zombie attacks in cloud computing networks using strong authentication. It aims to improve security in cloud architectures.
fog computing provide security to the data in cloudpriyanka reddy
Fog computing extends cloud computing by providing security and data processing capabilities at the edge of the network, close to end users and devices. It aims to address issues like high latency and bandwidth usage that can occur when all data processing is done in the cloud. Fog computing deploys computing, storage, and applications closer to end devices and users in order to improve response times for latency-sensitive applications like smart grids and connected vehicles. It creates a distributed network that balances resources between the cloud and edge devices.
Fog computing extends cloud computing by providing security and data processing capabilities at the edge of the network, close to end users and devices. It aims to address issues like high latency and bandwidth usage that can occur when all data processing is done in the cloud. Fog computing deploys computing, storage, and applications between end devices and cloud data centers so that data can be processed locally when needed. This helps enable real-time applications like smart energy grids that require low latency responses by running applications on edge devices instead of sending all data to the cloud.
Cloud computing involves clusters of servers connected over a network that allow users to access computational resources and pay only for what they use. While cloud computing provides advantages like flexibility and cost savings, security is a main concern as user data is stored remotely. Fog computing is a new technique that extends cloud computing by providing additional security measures and isolating user data at the network edge to enhance privacy. It aims to place data closer to end users to improve security in cloud environments.
MIST Effective Masquerade Attack Detection in the CloudKumar Goud
Abstract: Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. We propose a different approach for securing data in the cloud using offensive decoy technology. We monitor data access in the cloud and detect abnormal data access patterns. When unauthorized access is suspected and then verified using challenge questions, we launch a disinformation attack by returning large amounts of decoy information to the attacker. This protects against the misuse of the user’s real data. Experiments conducted in a local file setting provide evidence that this approach may provide unprecedented levels of user data security in a Cloud environment.
