Storing encrypted files is critical for companies that offer sensitive information online. But improperly encrypted files can be an equally risky scenario as it leads to a false sense of security. The process of having improperly encrypted files in storage is known as Insecure Cryptographic Storage (ICS). There is a variety of factors that can lead to ICS, including these:
How to avoid Insecure Cryptographic Storage
Even if the program itself is encrypted, some information may be accessed through databases, registry data and temporary (temp) files. This can result in sensitive data being accessed as unencrypted data, which can then be used by the malicious user for personal or financial gain. Compromising of company accounts usually leads to the stealing of confidential client or customer information.
In order to avoid this type of breach, developers should locate and identify all data that needs to be encrypted. Sensitive data should not be able to be easily overwritten, while sensitive memory areas should be immediately overwritten. Here is a list of steps and processes that can be used to avoid ICS from leading to a potential data breach or other detrimental losses to the company.
By overwriting memory as soon as it is no longer needed, potential unencrypted data can’t be accessed by users with permissions and malicious attackers alike. Following the correct safety protocols and methods outlined in this article will help in keeping company data secure.
