Cloud Storage Security Controls
Ask anyone who has fought in a war and they will tell you it’s an experience you can’t emulate. Many people have seen the eyes of their enemies as they fight. But what happens when your enemy is a thousand miles away, yet has all the information they need to know about you; location, strength, response time etc.
The world is run on information. Little 1’s and 0’s sent to the right place can do a lot more damage sometimes than any gun. And it is becoming obvious that the information we keep on our computers is no longer as safe as we’d hope.
Take Cloud storage. This is a current buzzword for information storage, and quite an amazing thing it is too. Networked data centers which negate the need for hard drives and disc drives to a certain extent. Information available 24 hours a day, 7 days a week from any physical location with internet access.
Innovative? Yes. Convenient? Certainly. But how much trust to you put in a system that can be accessed anywhere, and by anyone given the right tools and talent?
People such as Joseph Thomas Colon were able to hack into a secure database (the FBI in this instance.) Is it really such as great idea to keep your files permanently online, transferring them to other servers without considering the security issues?
Before considering putting your information in Cloud storage, consider the levels of control that you will require. The dictionary definition of a security control is thus: ‘ …safeguards or countermeasures to avoid, counteract or minimize security risks.’
Here are 4 examples of such controls:
Ensure the storage has at least some form of warning system that can act as a deterrent to unlawful access.
This is the electronic equivalent of the sign you would put in your window that says “Warning: Guard Dog on Premises.”
Examples of these include:
- Logon Warning – Ensure that a person is aware of the rights to enter your site or information storage.
- Creation of appropriate access banner on entry pages
- A deterrent control tries to stop malicious activity before it even begins.
Ensure that any security issues have already been broached. By managing the vulnerable parts of the storage, damage can be limited.
One example of this would be the inclusion of a proxy server.
This can act as a ‘bouncer’ between your information and the person(s) wishing to access it. Requests for your information can pass through this server, reducing the risk of a security breach.
These security issues can be resolved after an attack or damage has taken place. Real time security is important.
An example might include the changing of passwords and usernames as soon as you are alerted to the security breach. Another might be a limitation of the time spent on your Cloud storage, to minimize potential breaches.
The downside to corrective controls is that often, a breach must have taken place, allowing you to see where you need to plug the holes as it were, in your system security.
These controls will detect any unlawful users, slaving itself to the corrective and preventative controls to ensure a minimal amount of damage. This might include a complete listing of possible ‘what if…’ scenarios. Using a plan of development, you can often stop an attack before it begins.
An example might be hiring or yourself trying to unlawfully access your information in an attempt to test the defenses.
Try to keep these four controls in mind when requesting, using or accessing information in Cloud storage. By using one or all of these controls, you can really limit the potential damage that may occur when keeping your sensitive information completely online.
