Just about every day, I hear yet another horror story about data loss.
To my ears, that term — ‘data loss’ — doesn’t do the problem justice. ‘Data loss’ sounds almost innocuous, too much like ‘Gee, I misplaced my gloves, anybody seen them around?’
Cloud computing that involves processing sensitive or regulated data in shared environments needs extra scrutiny in terms of security (as well as codifying requirements, defining a cloud services contract, managing the transition from in-house to cloud, and overseeing the resulting mixed IT environment).
Cloud security is at risk when…
You don’t have an adequate cloud-oriented governance/risk/compliance framework,
The hypervisors in your virtualized infrastructure harbor vulnerabilities that can be exploited,
It’s possible to infer information about one virtual machine by observing the state of the shared system from another aspect of the underlying system — which might enable malicious code execution, or
When vulnerabilities are introduced by incorrect configuration of a hypervisor and/or its related tools.
Rare is the information technology professional these days who doesn’t understand the prodigious efficiencies and savings that can be derived from virtualization . Yet, too often virtual machines are deployed insecurely. One Gartner analyst has estimated that 60% of virtualized servers will be less secure than the physical servers they replace.
That’s because too often virtualization projects tend to be developed and deployed without considering security. This can result in vulnerabilities that enable bad guys to compromise the hypervisor/ virtualization layer (e.g., DoS attacks), which can spread to all hosted workloads.
Malware comes in many flavors. I’m focusing now on one of the most pernicious, advanced persistent threats (APTs), because these frequently use the techniques of zero-day attacks to remotely manipulate a system while remaining virtually invisible to standard defenses.
Targeted zero-day attacks are proliferating — and focusing more and more on smaller businesses because these tend to have weaker defenses. Some security experts say that if your security posture can be bypassed with custom malware, you’re probably already compromised.
The ever-richer user information on social media presents an irresistible opportunity for ‘fraudsters.’ Because it’s so easy to research a target online, attackers have developed very effective masquerading and social engineering tactics that can fool even the most sophisticated users.
