5-practical formula for media disposal according to ISO 27001 Certification (ISMS)
Today, media devices are
more uncommon than they were a few years prior, on the grounds that the current
pattern is the cloud, in spite of the fact that there are still many
individuals utilizing pen drives, outside hard drives, and so on. What's more,
obviously, all the data in the cloud is eventually put away on a worker, i.e.,
its hard circle, which is additionally a media devices. As you will see later
in the article, media devices should be discarded safely.
ISO 27001 Certification is a worldwide norm for the insurance of data, and we will
perceive how this standard can assist us with the removal of media devices.
To start with, we should
distinguish what media we have to deal with, just as why and how we can safely
discard them.
What are media?
Contemplating that, in ISO27001 Certification, the most significant thing is the data, we have to deal with the media
that we are utilizing to store the data. Yet, I don't get my meaning by
"media"?
For the most part, in this
unique circumstance, a medium is a gadget that is utilized for putting away
data, so media would incorporate hard drives, USB pen drives, outer hard
drives, CDs, DVDs, and so on.
Confidential information
A ton of organizations have a technique for the characterization
of their data, on the grounds that not all media have a similar data, and not
the entirety of the data has a similar incentive for the business. For
instance, there is a major distinction between a USB pen drive containing a PDF
record with an introduction of the business (which can be considered as open
data), and a USB pen drive containing the organization's information base of
customers (which can be considered as classified).
Clearly, if the data is public,
we can share it in the open area, on the grounds that there isn't a danger of
classified data spillage.
However, in the event that the data isn't open (classified, confined,
inward, and so forth.), we have to store and discard it in a safe manner, since
it can convey a danger of secret data spillage, which can pulverize the
business, just as indicating rebelliousness with lawful guidelines (like the
GDPR).
5 tips for disposing of media
In the event that you have a media device putting away data named
private (or some other basic level for the business), as we have seen
beforehand, there are dangers identified with it. Fortunately you can deal with
this hazard, utilizing a hazard evaluation and treatment procedure. This
article may be intriguing for you: ISO 27001 Certification hazard appraisal and
treatment – 6 fundamental advances.
We should see a simple model about how to treat this
hazard. You have a benefit, which is, for instance, a hard drive containing
classified data about the business. This hard drive was introduced on a data
framework (a worker), yet you chose to move data to another data framework,
e.g., to another worker or to the cloud. This unique hard drive will be
utilized for another reason and, in the wake of duplicating all information,
you have to deal with the first data, which ought not be gotten to by
unapproved individuals.
For the treatment of this hazard, you can diminish it by actualizing ISO27001 Certification control A.8.3.2 Disposal of media security control, and
here are some basic approaches to execute this security control:
Physically pulverize the media: You can do
this, for instance, by cremation or destroying, and so forth. This physical
devastation is additionally appropriate to harmed gadgets. However, be
cautious, in light of the fact that a harmed media device can likewise have
touchy data that could be reestablished, so to evade this, you ought to
obliterate it genuinely.
Securely erase the data : There are
programming instruments that you can use to overwrite the data, or to erase it
in a safe way.
Select an outer party: There
are a ton of organizations offering the assistance of demolition of your media,
yet here you have to take care with the choice of the supplier by
characterizing a non-divulgence understanding.
Avoid the total impact : It is better
in the event that you abstain from having a ton of media containing non-touchy
data, since something inside the gathering could become delicate data.
Register the removal : Registering
the removal furnishes you with valuable data for review trails (what media has
been demolished, or what media is reusable, and so on.).
My preferred method
I have left the best for the end, since now you know the
basic ways for the removal of media, yet now I will educate you regarding my
preferred method.
As Lead Auditor, I have
inspected a great deal of organizations around the globe, and I have seen
organizations erasing data and discarding data utilizing private programming
arrangements, which, at times, are costly. In different cases, a few
organizations are choosing outside suppliers that are specialists in the
administration of removal, yet this likewise has an expense.
My favored strategy is simple and free:
1. Encrypt the whole hard plate, utilizing a solid calculation and
utilizing a protracted secret phrase.
2.
Delete all the data in a protected manner,
utilizing programming arrangements (there are a ton of free arrangements).
3.
Physically demolish the media gadget
(cremation or destroying, and so on.).
In actuality, this
technique would just be appropriate to the most basic and touchy information,
and for information with less criticality, just one of these strategies will be
sufficient.
Keep calm and sleep-well
In the event that you play out these means satisfactorily, it is
difficult to recuperate the data – so you can try to avoid panicking and sleep-well.
ISO 27001 Certification can
be a decent apparatus for the safe removal of media containing classified data,
since it can assist you with recognizing the dangers, treat them, and actualize
security controls to discard the media in a protected manner. Thus, in the
event that you need to resist the urge to panic, use ISO 27001 Certification as
an apparatus, and recall my favored strategy for the removal!
