    Implementing Database Security

    The time has come when data security is one of the most challenging jobs for organizations. A database is a systematic arrangement of data where the data is organized. A database usually holds the foundation of an association; its logs, clients, staff and financial information for both organization and its clients. All important information is left in the hands of database executive with no security guidance.
    The tragic truth is that an organization has to spend lots of energy, money and time to secure its online resources. Yet, one fragile spot and the database can go down. As indicated by Dark Reading article, it can hardly take 30 minutes or less by an ordinary hacker to get in and out of an organization’s database with a goldmine of information.
    The base of an organization’s information and data security is laid upon 3 principles: availability, integrity, and confidentiality.
    Availability: Data should be available at all the necessary times and to the appropriate users only. It should be tracked who accesses and what data he accesses.  Moreover, the data should be kept up-to-date.
    Integrity: The verification should be done whether the external data has correct formatting and the input data is accurate. The data should be according to the workflows of the organization and the data changes should be reported.
    Confidentiality: confidential data should only be available to the right people only. Encryption should be done to secure database from internal and external breaches.
    SQL injections buffer overflow vulnerabilities which can help a hacker to mess with program’s logic. Weak authentication is the most common threat which can affect database security.
    Following are some practices which can be done to implement database security:

    • Data covering, or permitting clients to get to certain data without having the capacity to view it, credit or debit card procedures or amid database testing and advancement, for instance, helps to secure the privacy of the database.
    • Encrypting all database activity, consider password to secure and encoding the entire database backup so that if the backup data is lost or stolen it is difficult to get to the information.
    • Secure against SQL injections by using questions which are in a certain boundary to keep malignant inquiries out of the database. Static Code Analysis is a basic tool for associations creating applications as a gateway to databases for slicing SQL injection, cradle flood, and badly designed issues.
    • Audit the data access and control the offline copies of it.
    • Backup of the database should be set to avoid disasters.
    • Proper maintenance of availability, integrity, and confidentiality should be done by expelling any unspecified elements to protect the database.
