s your database optimally secured? Even though everyone wants to answer, yes, many may stumble upon it. If you are confident to answer this question with a confident yes, keep on reading.
Nowadays, on keenly following it, you cannot get past a single day without hearing news about some data security breach. Many companies are losing their valuable and sensitive data, whereas it ends up in big financial losses in many other cases. A study shows that, on average, data breaches cost about $7 million and incalculable damages to the companies’ brand image, consumer trust, and significant personal losses to the victims.
Considering these facts, the enterprise database users need to secure their invaluable company data as the hackers are growing in numbers, and their tactics are getting much stronger.
The business owners and database administrators must do everything possible to prevent any scope of data breaches and protect their valuable data stores. Failure to do it well will result in bigger losses than expected for both the company and the customers, which may ultimately spell disasters of very big proportions.
Is your data secured?
As the businesses grow and their practices in a data management change, many executives and DBAs may start wondering whether their customer data is well protected. As one states to examine the current state of security, including the protocols and procedures followed, there are be several loopholes in it which needed to be patched.
In case you do not have sufficient knowledge about these get professionals to help you out here. Further, we will discuss some tips for doing a database security audit properly.
Check all the records and try to keep the structure simple. Inspect all the files and understand what types of data your enterprise is collecting and saving. Also, ensure that your data collection and usage practices are compliant with the state laws regarding data usage and security.
Most of the time, you will be surprised to see that your systems and the third-party applications you use may inherently store a lot more than what you have been thinking about doing an audit. Most of these may, however, be of no use to you now or in the future. You may pare down any additional fields needed for future data collection and delete those parts of the old data stores that are not needed anymore.
Doing the above steps will help prevent hackers from accessing your databases to get something extra in any case of a breach. It will also ensure cleansing your systems in terms of saving storage costs and offering more focus on valuable and usable data.
Step 4: Maintain both online and on-site security – You may be having restricted access practices, firewalls, and security passwords in place to protect your data. Make sure that you implement the same not only online but offline at your in-house operations too.
Step 4: Many DBAs tend to leave their data inadequately protected by giving the hackers a tempting opportunity to intrude through these weak points. Organizations of any size need to physically and virtually implement adequate security features to ensure that it is made difficult, if not impossible, for hackers to gain access to your valuable data.
Train the employees and monitor
As pointed out by RemoteDBA.com, training the users on proper and safe database handling practices is also essential to keep your data safe. Ensure training opportunities to all employees from time to time to reiterate the importance of following the security best practices to handle data. Also, set up a monitoring system so that all the employee activities about data is monitored to identify anything unusual at the very first point.
While planning the database best practices for the employees, make sure that people only have access to the necessary data to complete their job-related tasks. Also, put processes and systems in place to alert the concerned about any suspicious database activities.
Dispose of the unwanted records – If you no longer need any data store, it is also essential to dispose of the same in a timely and secure manner. Never leave customer data in hard or soft form unprotected just because you no longer need those for any business purposes. Have a foolproof disposal protocol, and also stick to it strictly to avoid the scope of any data breaches.
Be planned for an attack – Even though it comes as the worst-case scenario, you should always be prepared to tackle an attack on your database. So, set alerts and measures in case of an attack on your database and make sure it is functioning properly. You need to have a proper backup and restoration plan to be run in case of a breach.

All these tools and measures will help keep your database safe and help you bring a data-conscious culture across all organizations’ levels for best results.
The Most Common Threats – An Enterprise Database Is Exposed
Denial of Service – admittance to arrange applications or information is denied to the planned clients. A straightforward model can be smashing an information base worker by misusing a weakness in the data set stage. Other regular disavowals of administration methods are information debasement, network flooding, worker asset over-burden (basic in information base conditions).
Database Protocol Vulnerabilities – SQL Slammer worm exploited an imperfection in the Microsoft SQL Server convention to compel forswearing of administration conditions. It influenced 75,000 casualties in a little more than 30 minutes drastically hindering general web traffic.
Weak Authentication – acquiring real login accreditations by ill-advised path adds to powerless verification plans. The aggressors can access a real clients login subtleties in different manners: by over and over entering the username/secret phrase blend until he finds the one which works (normal or powerless passwords can be speculated effectively), by persuading somebody to share their login qualifications, by taking the login certifications by duplicating the secret phrase records or notes.
Backup Data Exposure – there are a few instances of security penetrates including the robbery of information base reinforcement tapes and hard plates as this media is suspected of as least inclined to assault and is frequently
totally unprotected from assault. All these security dangers can be represented by unapproved information perception, erroneous information adjustment, and information inaccessibility. Ensuring the classified/touchy information put away in an information base is really information base security. There are diverse security layers in an information base. These layers are: information base head, framework director, security official, designers and worker, and security can be added at any of these layers by an assailant.
A Complete Data Security Solution Must Take Into Consideration the Following
- Secrecy/Confidentiality-alludes to the insurance of information against unapproved exposure
- Integrity – alludes to the anticipation of inaccurate information adjustment
- Availability Of Data.- alludes to the anticipation of equipment/programming mistakes and vindictive information access refusals making the data set inaccessible.
- Splicing – Here, ciphertext esteem is supplanted by various ciphertext values.
Replay – Replay is a sort of assault where ciphertext esteem is supplanted with the old form recently refreshed or erased. Information bases are one of the most loved objectives for aggressors in light of the information these are containing and furthermore in view of their volume
Information bases Need Tighter Security To Protect Against Threats
All ventures utilize an information base administration framework (DBMS) innovation to store basic business information. All information is significant, however private information matter most.
A solitary interruption that bargains private information, for example, Visa numbers or money related information can make gigantic harm to an association, regardless of whether large or little. Information bases are frequently the ideal objective of such assaults, to a great extent since they hold the most important information and are weak except if deliberately made sure about.
Assaults on the information base can likewise be grouped into two kinds, for example, latent and dynamic assaults.
Passive Attack: In a detached assault, the assailant just watches information present in the information base. Here, the assailant doesn’t make changes to the information. The latent assault should be possible in the accompanying three different ways:
Static spillage: In this kind of assault, data about information base plaintext qualities can be gained by watching the preview of the information base at a specific time.
Linkage spillage: Here, data about plain content qualities can be acquired by connecting the information base qualities to the situation of those qualities in the file.
In this, progressions completed in the data set throughout some undefined time frame can be watched and broke down and data about plain content qualities can be gotten. Dynamic Attacks: Inactive assaults, genuine information base qualities are adjusted.
These are riskier than aloof assaults since they can deceive a client. For instance, a client will get some unacceptable data because of an inquiry. There are various methods of performing such sort of assault which are referenced beneath:
Spoofing – In this sort of assault, the ciphertext esteem is supplanted by a produced esteem. Medical coverage Portability and Accountability Act (HIPAA), and European Union guidelines.
- Performing a stock, everything being equal, including nonproduction.
- Discovering and ordering information bases dependent on the affectability of information.
- Establishing security approaches for all information bases.
- Converting the approaches into activities and conveying them across information bases.
- Taking proper safety efforts, for example, encryption, reviewing, access control, checking, and information concealing.
- Looking for an extensive information base security arrangement that can execute hearty information base security with ease.
