Cloud security issues and challenges

IT Status "Password doesn't match" error. 4Help is aware that after you change your VT Google password, you will be unable to log on to VT Google Apps services including Mail, Drive, Groups, etc. 4Help is notifying the appropriate people. 12:00 Noon: Engineers have found a backlog on Google password replication. Once the backlog clears you should be able to log on with your changed password that you set earlier. You may be able to log on with your old VT Google password until the system catches up and syncs the new password.

Today, Cloud Computing is the preferred choice of every IT organization since it provides flexible and pay-per-use based services to its users However, the security and privacy is a major hurdle in its success because of its open and distributed architecture that is vulnerable to intruders Intrusion Detection System (IDS) is the most commonly used mechanism to detect attacks on cloud This paper provides an overview of different intrusions in cloud Then, we analyze some existing cloud based intrusion detection systems (IDS) with respect to their type, positioning, detection time, detection technique, data source and attacks they can detect The analysis also provides limitations of each technique to evaluate whether they fulfill the security requirements of cloud computing environment or not We emphasize the deployment of IDS that uses multiple detection methods to cope with security challenges in cloud

Intrusion Detection System in Cloud Computing: Challenges and opportunities

Cloud computing systems represent one of the most complex computing systems currently in existence. Current applications of Cloud involve extensive use of distributed systems with varying degree of connectivity and usage. With a recent focus on large-scale proliferation of Cloud computing, identity management in Cloud based systems is a critical issue for the sustainability of any Cloud-based service. This area has also received considerable attention from the research community as well as the IT industry. Numerous Cloud Identity Management Systems (IDMSs) have been proposed so far; however, most of those systems are neither widely accepted nor considered highly reliable due to their constraints in terms of scope, applicability and security. In order to achieve reliability and effectiveness in IDMs for Cloud, further extensive research needs to be carried out to critically examine Cloud based IDMSs and their level of security. In this work, we have holistically analyzed Cloud IDMSs to better understand the general as well as the security aspects of this domain. From the security perspective, we present a comprehensive list of attacks that occur frequently in Cloud based IDMSs. In order to alleviate those attacks, we present a well-organized taxonomy tree covering the most desired features essential for any Cloud-based IDMSs. Additionally, we have specified various mechanisms of realization (such as access control polices, encryption, self-service) against each of the features of Cloud IDMSs. We have further used the proposed taxonomy as an assessment criterion for the evaluation of Cloud based IDMSs. Our in-depth analysis of various Cloud based IDMSs reveals that most of the systems do not offer support to all the essential features of Cloud IDMS and the ones that do, have their own certain weaknesses. None of the discussed techniques heuristically covers all the security features; moreover, they lack compliance to international standards which, understandably, undermines their credibility. Presented work will help Cloud subscribers and providers in understanding the available solutions as well as the involved risks, allowing them to make more knowledgeable decisions while selecting potential Cloud IDMSs that best suits their functional and security requirements.

Cloud Based Secure and Privacy Enhanced Authentication & Authorization Protocol

NoSQL databases are easy to scale-out because of their flexible schema and support for BASE (Basically Available, Soft State and Eventually Consistent) properties. The process of scaling-out in most of these databases is supported by sharding which is considered as the key feature in providing faster reads and writes to the database. However, securing the data sharded over various servers is a challenging problem because of the data being distributedly processed and transmitted over the unsecured network. Though, extensive research has been performed on NoSQL sharding mechanisms but no specific criterion has been defined to analyze the security of sharded architecture. This paper proposes an assessment criterion comprising various security features for the analysis of sharded NoSQL databases. It presents a detailed view of the security features offered by NoSQL databases and analyzes them with respect to proposed assessment criteria. The presented analysis helps various organizations in the selection of appropriate and reliable database in accordance with their preferences and security requirements.

Security of sharded NoSQL databases: A comparative analysis

Cloud computing, a relatively new concept and has gained an immense attention of research community in the past few years. RaD organizations and industry are investing a lot in cloud based research and applications. Similarly on theconsumers' side organizations are moving their business on cloud to provide flexibility and conceive ever increasing computational power requirements. In spite of significant advantages, and its demand, different stakeholders are still reluctant to migrate to cloud. A major hindrance is the absence of reliable and comprehensive access control mechanism for cloud resources. We have analyzed existing cloud based access control systems and evaluated those using NIST defined access control systems evaluation criteria. Based on our analysis we have proposed future research direction in the domain of access control systems for cloud based environments, which will eventually pave the way towards cloud adoption.
