Data Recovery of damaged of lost database

Regardless if you are in need of DBASE, MySQL, MS-SQL,Oracle or Exchange Server Data Recovery services, KUERT Belgium recovers lost or damaged data from all kind of database systems, independently from any kind of Server OS.

Database Management Systems ( DBMS ) do exist in nearly every corporation or business and have a core functionality to business related descisions. DBM-Systems do guide us in many different functions, as a postbox, an ERP or as an bookkeeping software. Without databases, businesses can´t manage nor analyse their stored informations.

Because of this reason, the data loss within a database has an direct effect to the productivity of each business. Once informations can not be accessed and different departments are inable to write invoices, orders or to manage a project, it results in loss of value of productivity, time and money.

KUERT Data Recovery Belgium takes care of the recovery in case of lost or damaged Database Management Systems, regardless if the cause for data recovery is of logical of physical nature / damage.

The threat to modern database systems can have different causes:
  • Damages to hard disc drives / RAID- or NAS Systems which carries the database
  • Power-Shortages or damages caused by overvoltages
  • Damages caused by fire or water

Scenarios of damages which are created by IT-Security threats:

1. High rate and unused queries to the database

Every user / administrator, who has access to an existing database, but who doesn´t use this database frequently as part of his daily duties, means a security threat, because the grant of access and access rights can be abused. Granting too many persons access to a database results in the effect that the necessary knowledge regarding the table structure of the database is not given anymore. This creates a risk for misconfigurations and potential abuse.

2. Abuse of access rights

Data theft and economical espionage are more related topics to computer- or IT-Forensic. But especially databases do store the complete knowledge and economical backbone of a company.  If an employee disaffects from a company, in a best case rules and policies for the access rights are managed correctly in order to prevent a company from potential risks.

3. Attack of Database via SQL Injection

A successful attack via SQL Injection gives the attacker unlimited access to all areas of an database. SQL Injection adds unauthorised and malicious entries to the database with the help of an SQL Data-Channel wich is attacked. Usually this is realised by Web-Applications / Internet Applications or stored procedures. If the attacker calls one of the injected entries stored in the database, a full access to it possible. Rights for reading, copying and of course deleting included.

4. Infestation and modification of the database by malware

The NSA-Affair in 2013 / 2014 put in spotlight how hacker, cyber criminals and spys do use malware to archive their goals. Besides manipulated E-Mail adresses, also malicious software comes into play to infect the systems which do carry company sensitive data.

5. Wrong and careless auditing of processes

In most of the developements which do interact with databases, the automatic storage of database transactions is implemented. This requires a stronger view to the auditing of all database activities. If the auditing process is not used frequently and also not reviewed frequently, it means a security risk to a company.

Businesses with weak or none auditing mechanisms of database transaktions will recognize, that they are not really competitive. Because some of their clients want to see certificates, that give proof that sensitive data is audited frequently and stored in a secure way.

Many businesse do use special software for auditing their databases. In most of the cases thease auditing programms have been developed by the database manufacturer. In some cases business refer to adhoc analysis or to procedures written and described in handbooks / user-guides. Thease kind of activities do offer a secure basement, but they don´t go into details and don´t support aspects regarding the early recognition of potential threats or attacks, neither they do offer a check of the database under IT-Forensic conditions. Even heterogenic database structures do divide from each other. In order to archive an audit-process which is best as possible, this point should kept be in mind.

6. Managing access to storage devices

Storage devices are quite often a goal of potential attacks and very often thease kind of storage devices are completly unprotected. This keeps the doors open for potential security risks, data theft of hdds and tapes by employees. Wrong auditing and control of activities of administrators with lower access rights to company sensitive informations are also a risk of security. To prevent Backups and Copies, policies are needed which are limited to only a few persons and equip them with the necessary rights.

7. Checking vulnerable and misconfigurated databases

It is hard to find security holes within a database. More often you will find databases which still do have configurations and user accounts which are still existing right from the installation. Like a "Demo" Account or a "Support" user account. Potential attackers do know thease holes and accounts and they do use them, once they have located them. Unfortunatly companies struggle in keeping up once established processes for frequently checking the databases on a long term. Even in case of existing updates, it can take months unless thease updates are used and installed. A study of an independent oracle user group showed that 28% of all Oracle users never have installed a security update. In some cases they know they did, but can´t tell when. 10% said that they would need 1 year or more unless a security patch is getting integrated in their systems.

8. Unmanaged business critical data

Many companies and administrator struggle when it comes to a proper inventory of critical data objects. Forgotten or older databases can hold critical informations. Even new databases can be created, called or born by applications which have been started in test-environments and by this, even the IT-Security team has no chance to take notice of it. Sensitive data, stored in databases are threatend as long as there is no instance for control or rules and roles for managing access rights are implemented.

9. DoS Attacks

So called "Denial of Service" (DoS) attacks of company or governmental websites take place more and more often. Thease kind of attacks do belong to a category of networkbased attacks. DoS attacks can be generated via the use of different sorts of technology. Usually the targeted database is getting so many queries until the server isn´t able to serve the called content within a dedicated amount of time. Queries and CPU-Time can´t handle thease queries anymore and as a final result the server crashes completly. The motivation behind a denial of Service attack is based on blackmail or extortion. The attacker penetrates the server of the victim as long until the victim is paying the attacker. The younger history shows, that DoS attackers are not always driven by moneytory aspects. Quiet often DoS Attacks can be a radical form of viral protest.

10. Lack of IT-Security Know-How and further education

Internal IT-Security checks are not very often on the same level to keep pace with exponential data growth. And many companies are not well equipped in case of security incidences like attacks, data theft or data loss. The cause for this is based in a lack of knowledge and a lack of the business itself invest something in order to strenghen it´s own IT-Security. Frequently IT-Trainings and courses for the IT-Staff are as much important as investing money into hardware- software-based it-infrastructure.
