Storing data is one of the most important aspects of securing data from a personal as well as organisational point of view. We all know how vulnerable databases can get in the even of unethical hacking and cyber attacks. If not secured properly, hackers may easily steal or corrupt the sensible data causing irreversible damage not only to the data but also to the system. However, by having an appropriate data backup in place, one can still be able to retrieve their sensible data which can minimize the overall damage done.
Internal And External Storage
Data can be stored in both internal and external memories. Storing data in an internal memory, such as hard disk drive of a computer or in the database of an organisation can prove to be vulnerable if not secured properly. In the present digital world, the value of an organisation depends on how effectively it can protect the privacy of a customer. This is the reason why most organisations have comprehensive data backup plans in place to keep the sensitive data safe in case of any unexpected cyber attacks.
On the other hand, data stored in external memory devices such as CD’s, DVD’s, external hard drives, pen drives, etc., are deemed to be much more secure, especially, from a personal point of view. With this type of data storage, one can always carry sensitive data with themselves without having to store it in a computer. One can simply connect the memory device to the system and access the data when required. One can also store these devices in a physically safe location where hackers can’t reach.
Data Storage And Encryption
Storing data can further be enhanced by protecting it against unwanted access. For this, a proper data encryption is necessary in order to prevent any unauthorized access to the stored data. This involves locking the confidential data with a key which would be available to only the top authorities in the business administration. Thus anyone from the office does not have access to the stored data that protects it from being exposed to outside groups and keep it safe and secured.
Today, many businesses store confidential information as PII’s (personally identifiable information) in digital form. Secure Socket Layer (SSL) and Transport Layer Security (TLS) are the two encryption technologies that are currently being used for transmitting data securely over various networks. Though encryption may not prevent the data from being stolen by outsiders, it can render the stolen data useless. Also, today, various data encryption software technologies are available which require passkeys to be able to access the already encrypted files making them even more secure.
Storing Sensitive Data
It is very important that one keeps the custody of all the data that is deemed to be sensitive. This may include one’s research work, customer details, employee details, bank papers, business credit cards among others. And this can only be achieved by implementing effective data storage techniques such as multilayered encryption, tokenization, data masking, etc. Data can also be stored effectively by limiting its access only to privileged personnel and setting up some strong passwords. Same applies to external data storage as well.
