Virtualized Server Security
Virtualized servers are faced with similar security concerns as their physical counterparts. The only difference is that virtualized servers have other threats that are specific to virtualized machines. Virtualization is a new technology, and with any new technology, there are new threats and security concerns that will accompany it. When compared to its physical counterparts, virtualized servers are more prone to threats because they are clustered. If one virtual server is attacked, the other virtual servers are most likely to be faced with the same attack. Some of the risks faced by the virtual server can be mitigated through effective and efficient planning.
Lack of information security team
The failure to involve the information security team in the initial planning and architecture stages would result in security threats to the virtualized servers. The organization could have a secure physical server and would be extending the capabilities of its physical server, but the failure to conduct, and effectively planning would make the virtualized server prone to attacks (Luo, Lin, Chen, Yang, & Chen, 2011). With a virtual server, there is a new layer of software that is added and this new layer should be closely analyzed to determine it would not leave the server vulnerable. A vulnerable virtual machine could lead to the attack of the other virtual machines on the same host. Attackers can gain access to the host machine by exploiting the memory space...
Centralized telesaving control Managing cost-effective use of dial links centrally may no longer be possible. Overhead VPN tunnels impose overhead for dial-in users: encryption algorithms may impact the performance of the user's system, there will be an increased protocol header overhead, authentication latency will increase, PPP and IP compression will perform poorly (compared to a direct link), and modem compression won't work at all. Support issues Replacing direct-dial links with VPN tunnels may produce some
The teaching staffs are also to be linked to the system via a wireless network. However in order to facilitate efficient learning, the system is to be linked via a Virtual Private Network (VPN) through an internet link. This therefore demands that there exists an internet connection infrastructure which comprises of the necessary routers, switches, cables and an Internet Service Provider with a very high uptime. What results can
Virtual Security Issues Many of the challenges in managing a virtualization security upgrade project revolves around the communication between members of an organization. The means or tools that communication efforts are based upon make no difference as long as there is a shared and accepted policy that is agreed upon between those who need to communicate. During times of transition, communication must remain in extra clear terms as the stress associated
Very High - IPSec works at the protocol level, independent of applications, therefore scalability is best-in-class Comparing the technological and operational benefits specifically in the areas of client access options, access control, client-side security, installation, and client configuration highlights just how differentiated the IPv4-based IPSec vs. IPv6 -based SSL protocols are from each other. In analyzing these differences, Table 3: Comparing Technological and Operational benefits of IPv6-based SSL and IPv4-based IPSec
Each onion router removes a layer of encryption to uncover routing instructions, and sends the message to the next router where this is repeated. This prevents these intermediary nodes from knowing the origin, destination, and contents of the message. 1.4. Lecture Survey. The predicted solution of the problems related to e-government administration depends on answering the following questions as brainstorming ideas to solve the problem and the features provided by the system
, 2005). In addition, the workload on clinicians is often increased past the point of reasonable because it is too intrusive and time consuming to document patient encounters during clinic time (Grabenbauer, Skinner, and Windle, 2011). The amount of information that can accumulate in a patient's record from multiple sources can be daunting and lead to information overload. CDS alerts can be so common that clinicians begin to ignore them.
