Abstract: We extensively review the literature on MITM to analyze and categories the scope of MITM attacks, considering both a reference model, such as the Open Systems Interconnection (OSI) model, as well as two specific widely used network technologies, i.e., GSM and UMTS. In particular, we classify MITM attacks based on several parameters, like location of an attacker in the network, nature of a communication channel, and impersonation techniques. Based on an impersonation techniques classification, we then provide execution steps for each MITM class. We survey existing countermeasures and discuss the comparison among them. Finally, based on our analysis, we propose a categorization of MITM prevention mechanisms, and we identify some …show more content…
In traditional data centers, where system administrators have full control over the host machines, vulnerabilities can be detected and patched by the system administrator in a centralized manner. However, patching known security holes in cloud data centers, where cloud users usually have the privilege to control software installed on their managed VMs, may not work effectively and can violate the Service Level Agreement (SLA). Furthermore, cloud users can install vulnerable software on their VMs, which essentially contributes to loopholes in cloud security. The challenge is to establish an effective vulnerability/attack detection and response system for accurately identifying attacks and minimizing the impact of security breach to cloud users. In [2], M. Armbrust et al. addressed that protecting ”Business continuity and services availability” from service outages is one of the top concerns in cloud computing systems. In a cloud system where the infras- tructure is shared by potentially millions of users, abuse and nefarious use of the shared infrastructure benefits attackers to exploit vulnerabilities of the cloud and use its resource to deploy attacks in more efficient ways [3]. Such attacks are more effective in the cloud environment
The security concerns for IaaS and PaaS models are described collectively because of their reliance over each other. The attacks on these two layers are of three types: attacks on the cloud services, attacks on virtualization and attacks on utility computing. Hardware virtualization, software virtualization, cloud software, utilitycomputing and Service Level Agreement (SLA) are considered some of the common security concerns for IaaS and PaaS.
In the book Exploring Language & Literacy chapter Preschool talks about diverse school, a diverse school is where there is different backgrounds and cultures for an example mexican, black, asian etc. In the book it says “The teachers were interested in learning how to better meet the needs of all the learners.” I think what the teachers do is admiring, to go out of there way to learn about the students cultures and backgrounds to better understand them. It so impressive, by doing this they have a better connection with the children. In their social skills they improve in indicating their needs and understanding else's emotions.
Organizations use the Cloud in a variety of different service models (SaaS, PaaS, IaaS) and deployment models (Private, Public, Hybrid). There are a number of security issues/concerns associated with cloud computing but these issues fall into two broad categories: Security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure-as-a-service via the cloud) and security issues faced by their customers.In most cases, the provider must ensure that their infrastructure is secure and that their clients’ data and applications are protected while the customer must ensure that the provider has taken the proper security measures to protect their information.
In 1984, former NFL player Kermit Alexander lost his mother, sister and two nephews due to a gang related shooting on the wrong family. The Alexander's family was not supposed to be targeted, it was a miss communication between the gang members. Alexander was so full of rage that he prowled the streets at night in search of the members that did this to his family, his goal was to give revenge for what they had done. The only reason he did not become a killer himself was because the mayor Tom Bradley made him promise to let it go and let the law handle the situation from there and in 1986 the killer, Cox was found and sentenced to death. Capital Punishment should be allowed because it stops the killer's from being able to kill again, it provides some closure for the families who have lost a loved one, and it is a deterrent showing what will be done to you if you do these heinous crimes.
Marvel has recently released a line of t-shirts based on the popular “Avengers” comic book series, that advertises two different t-shirts, one designed for males and one designed for females. These t-shirts have brought up various concerns regarding gender stereotypes/biases. This all started once the t-shirts hit the market. One of the first things people noticed was the color. The t-shirt that was created with males in mind, is sold in a shade of blue. On the other hand, the female constructed t-shirt is in between a shade of red and pink. These two colors are commonly categorized as male and female colors, blue is for boys and pink is for girls. This trend started many decades
at the innermost implementation layer, there is infrastructure-as-a-service (IaaS) model which is extended to form the platform-as-a-service (PaaS) layer by adding OS and middle¬ware support. PaaS further by applications on data, content, and meta¬data using special APIsis created to extends to the software-as-a-service (SaaS) model. all protection functions at all levels are being demanded by SaaS. At the other extreme, IaaS demands protec¬tion mainly at the networking, trusted com¬puting, and compute/storage levels, whereas PaaS embodies the IaaS support plus additional protection at the resource-management level.
Over the past several years the term cloud computing has become common in homes and organizations alike. Cloud computing can be defined as a pooled set of computing resources that are furnished via the internet. There are three types of cloud services typically available, these services are Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Organizations can benefit greatly from cloud services because they eliminate the need to buy and manage physical resources. Although such an action cuts cost it leaves organization victim to the vulnerabilities and threats that exist in cloud computing. Throughout this paper I will discuss the vulnerabilities and threats that come
While there have been some high-profile cloud-based outages, in many cases, cloud-based services are more reliable, affordable, and secure than on-site data centers. A cloud provider has the expertise and resources to build a more secure, resilient, and reliable data center than a typical small- or medium-sized business. For example, InfoSystems offers production-ready cloud solutions with a baseline Tier 3 data center, a higher-level SLA than large-scale providers, and a hands-on approach to cloud migration.
Traditionally, IT (Information Technology) security focused on securing the IT assets within the organization’s IT framework. However, with the advent of smart mobile devices, cloud computing, and remote connectivity, the IT landscape has changed dramatically in the last few decades. With these changes, the frequency of attacks by cyber criminals has increased as well. We constantly hear news reports of large-scale cyber attacks targeting financial, government and healthcare organizations. Moreover, the type of attacks have evolved to become more sophisticated and untraceable, making it difficult for security analysts to keep up with the every changing technological demands to successful prevent, analyze and thwart security attacks. This has now led many security experts to believe that having an effective defense mechanism in place is a much viable option than to be reactive to threats. This also makes sense from a business perspective. Companies want their IT investments to further their business goals and not to be constrained too much by focusing heavily on IT security, which could potentially lead to an increase in operational costs to tackle security issues.
tion. Therefore, Man-In-The-Middle (MITM) attacks that need to target specic IP address(es) and other types of attacks against node 's privacy can occur. In this paper a new version of MTM6D (MTM6D II) is presented to resolve the above shortcomings. Further- more, a suggestion is proposed to prevent black hole at- tacks, as a part of DoS attacks (in which a compromised router on the path between two hosts discards packets instead of forwarding them) and bandwidth depletion DDoS attacks (that only need the subnet ID instead of the exact IPv6 address of a target).
The paper ‘Log file 's centralization to improve cloud security’ proposes a centralized, secure and comprehensive architecture for log-based analysis for cloud computing platform [3]. It suggests the use of logs generated by cloud due to different activities performed, defining the policies of which log file should be kept and which files must be transferred, and reporting of the attacks and threats and attacks based on the analysis of these logs. Algorithms like map-reduce are applied which can report about the patterns which can lead to attacks based on comparison with the stored values. Updating the policies based on the new findings during the analysis of the logs files.
We assume that the public cloud infrastructure provides proper security and data backup solutions with a Service Level Agreement (SLA) and mechanisms to fairly share its virtual resources among all its running VMs. The last few years have witnessed the emergence of cloud computing as a rapid, limitlessly scalable, and cost-efficient alternative in contrast to the in-house data centers. The IaaS model delegates more control to the customers over the provisioned resources. Hosting Internet applications in the IaaS environment is an efficient way to start a new and a sustainable business that expands the IT infrastructure gradually with the business growth.
security risk management and solutions within cloud computing should be studied very well and in wide range to address these
Threats to data center systems have never been higher. In 2016, more than 4.2 billion records were exposed through data breaches. The threat landscape has
Today, cyber threats are becoming progressively more sophisticated, and attackers are harder to detect. What was once a seemingly straight forward safeguard using antivirus, antispam, and firewalls, has now grown into insidious and continuous system attacks. Within any enterprise, data is the forefront of its commercial capital, and any loss, reputation, or breach can result in catastrophic budgetary overhead. Organizations oftentimes ponder over lucrative security investments, sadly these aren’t the result of proactive but reactive measures. Attackers are fiercely penetrating enterprise networks, infrastructures, computers, and physical systems.
