Securing your cloud

Account credentials are a major cloud security issue because vulnerability scanners or penetration testing can’t determine if they’ve been compromised or if they’re being abused by attackers.
Compromised credentials become a problem when they are used. If  someone shared cloud authentication credentials(for an example an employee left the company and never used the credentials, the organization might never discover the exposure).

Another example like multiple attempts to log in simultaneously from geographical locations could also compromise the cloud security according to experts.

Azure VPS

A virtual private server (VPS) is a virtual machine service by an Internet hosting service.

It allows developers migrate applications and infrastructure without changing existing code and can run both Windows Server and Linux virtual machines. Announced in preview form at the Meet Windows Azure event in June 2012 the Windows Azure Virtual Machines comprise the Infrastructure as a Service (IaaS) offering from Microsoft for their public cloud. Customers can create Virtual Machines, of which they have complete control, to run in the Microsoft Data Centers. As of the preview the Virtual Machines supported Windows Server 2008 and 2012 operating systems and a few distributions of Linux. The General Availability version of Virtual Machine was released in May 2013.

Amazon Virtual Private Cloud (Amazon VPC)

Amazon VPC is isolated section of the Amazon Web Services (AWS) Cloud where can launch AWS resources in a virtual network, including own IP address range, subnets, route tables and network gateways .Also can create a Hardware Virtual Private Network (VPN) connection between a corporate datacenter and VPC.

For example, a public-facing subnet for your web servers that have access to the Internet, and place your backend systems such as databases or application servers in a private-facing subnet with no Internet access. You can leverage multiple layers of security, including security groups and network access control lists, to help control access to Amazon EC2 instances in each subnet.
