What are the security requirements and challenges of Grid and Cloud Computing?

Solution

security issues:

A. Policies:

1) Inside Threats: good supervision should be done for having trusted employees .
2) Access Control:Digital signature can be implemented
for access control.
3) System Portability: The problem of vendor lock-in
should be handled .

B. Software Security:

1) Virtualization technology: up to date version of
virtualization product should be installed for the
security reasons.
2) Host Operating System:should be up to date and
secure from hackers
3) Guest Operating System: should be up to date and
secure from hackers
4) Data Encryption:should be done on all the data for
its safety.

C)Physical security:

1) Backup:Either a backup plan should be provided
automatically for each customer, or they can use the
plans provided elsewhere in the cloud.
2) Server Location:It should be at appropriate place. Room should have adequate space and isolated. A
Cooling System and Fire Suppression System should
be installed there.
3) Firewall: Cloud Computing service providers should
provide a complete firewall solution to their clients.

Challenges:

A)No clear standard:Grid computing
uses various standards, but all grids are
not use same standards. Example all grid
operating system such as Linux, Apache,and My SQL are using WSRF,
WWW, SOAP and XML standards.

B)Distributed computing Vs Grid
computing: Grid computing involves
dynamic virtual organisation, resource
sharing and peer to peer computing. The
Grid intends to make access to
computing power, scientific data
repositories and experimental facilities
as easy as the Web makes access to
information. Same all facilities provide
the grid computing. So it is a challenge
for grid computing.

C)Lack of grid enabled software: The
software, which are enabled the grid
computing are less, It has limited
software on Grid. Much software has
not copyright issues and source code of
licence. It is need for more company
developing grid-enabled version, need
more developers on grid development
and need to develop open source
software.

D)Sharing Resources between Various
types of Services:Grid used for
sharing resource from various sites and
grid hosts. It handles a massive amount
of data as a grid platform. A lot of sites
and multiple servers gathered there it is
so complex infrastructure. It provides
difficulty for hardware resource sharing
within virtual organisation.
