As the cloud buzz is getting louder with every passing day you are tempted to take the big leap into the cloud but may have restrained yourself paranoid by ad infinitum cloud security discussions floating on the web. No one can deny the fact that your data is the lifeblood your business. So, undoubtedly its security is of paramount importance for survival of your business. As cloud computing is a paradigm shift from the traditional ways of using computing resources, you must understand its practical security aspects.
Is Cloud Computing Safe?
There can’t be a binary answer (Yes or No) to this question. But with my experience and as an authority on the subject I can tell you that technologies enabling Cloud services are not in any way less secure than the traditional or on-premise hosting model. Also, with the evolution of technology, the cloud providers are getting matured and almost all the providers are offering built-in security, privacy, data backups and risk management as a part of their core service.If you are not a big IT company then you must ask yourself:
· Can an on-premise solution or a traditional hosting provider match the same level of standard security and privacy requirement as provided by the specialist cloud provider whose core competency lies in providing state of the art security and privacy?
What is computer crime? Computer crime, often called “cyber crime” is any type of illegal activity that takes place on a computer with a network. Oftentimes, when you think of computer crime, you might picture a home user downloading a virus that wipes out his hard drive or spyware that hijacks her system for the purposes of spying.
Computer crimes can also affect businesses too and they do, sometimes with devastating results. For example, in 2012, the IRS paid a whopping 5.2 billion dollars in tax refunds to identity thieves!
Protect your business and improve your bottom line by staying one step ahead of the cybercriminals.
5 Common Computer Crimes
Invoking an external command in Python is a two step process:

Checking to see if a directory exists and then creating it if it is not present requires a few lines of code. Isn't Python great. 
Begin by importing the os module and use the exists and makedirs functions.
import os
if os.path.exists(somedirectory):
os.makedirs(somedirectory)
