Database Security Review

Database Management Systems are typically designed to store large quantities of sensitive information that is critical to business operations. An unauthorised access to, or tampering of this data could result in significant negative impact on normal operations.

Overview

Database security assessment is conducted to identify loopholes in security mechanisms and also about finding any misconfigurations of the database system.

The main target of database security testing is to identify potential vulnerabilities in a system and to determine whether its data and resources are protected from malicious intruders. Security issues resulting from insecure database architecture can destroy your brand reputation and cost a significant amount of money in lost revenue and compensation.

Why do you need Database Security Review?

A database management system in its default state is vulnerable to attack. Appropriate security measures around authentication, authorisation and logging should be conducted to ensure data stored on the database is secure. Database security cannot be assumed, but must instead be verified.

Our database review would help you with:

  1. Identifying security configuration errors in your database
  2. Promote security best practices
  3. Improves over all security postures of your database
  4. Reduce the attack surface and exposure to risk

Key benefits

Validating database security has multiple benefits that include:

  • Ensure data privacy and protection against insider threats
  • Safeguard your most valuable information
  • Database security helps during critical incidents such as ransomware, data breach attempts
  • Understanding and determining key risks to critical data storage
  • Identify and prioritize threat mitigation efforts considering acceptable risks 
  • Data security helps adhering to different regulations and standards such as GDPR, PCI DSS, ISO27001

Methodology

Reporting

The assessment-execution phase is followed by the analysis & reporting. Defendza performs analysis on the testing output, evaluates the risk impact and likelihood of exploitation in realistic scenarios before providing action plans to remediate the identified risks. All our reports address business as well as the technical audience with supporting raw data, including mitigation measures at strategic and tactical levels. 

The pro-active approach towards security

Cybersecurity is only effective when it is proactive. By identifying weaknesses and vulnerabilities before they are exploited, you ensure the integrity of your network. Frequent security assessments also create a more efficient system, helping to prevent data loss and minimise any downtime that would affect your business and your customers.

A fresh set of eyes

No one doubts the talent and commitment of your in house administrators and developers, or the great work they’re doing. But, by having a third party come in and perform an independent cybersecurity audit and review of your systems, you can ensure that no stone is left unturned. Our team of skilled cybersecurity experts will help to identify any vulnerabilities and weaknesses your team may have missed.

Logging

Event logging provides you visibility into the operation of your device and the network into which it is deployed. We review how the logs are configured and stored for all the devices under review

The very purpose of security is to be proactive and make it challenging for a threat actor attempting to compromise your network. This might not be enough and you need to able to detect the actual breaches as they are being attempted. Reviewing logs regularly could help identify malicious attacks on your device or network in general.

Patching

As part of the audit, we review the device operating system and version in use. We review the patching policy and if the device under review is part of this policy as well.

A patch management policy is important for keeping your system's security regularly updated. Patch management involves obtaining, testing, and installing several patches to the computer system to keep it safe against malware attacks. The tasks carried out during patch management include: keeping up to date on which patches are available, determining what patches are right for your system, making sure that these patches are properly installed, testing your system after installation, and documenting all related procedures.

Database structure review

This would involve reviewing the database structure itself. In this, checks are made to identify if default settings, such as default DB tables, have been changed and whether unnecessary built-in functions like stored procedures have been disabled.

Roles and privileges review

A privileged user is someone who has access to critical systems and data. This user is typically a DBA, but not exclusively. These users have potentially unrestricted access to perform actions not available to non-privileged users. 

Besides the possibility that the privileged user will inadvertently or maliciously impact the database through such actions, an attacker can attempt to gain access via the privileged user account.   Those accounts are a prime target for attackers who wish to hijack the account to access data or to introduce malware.

User accounts and passwords

Database authentication mechanism is reviewed to ensure that default database accounts are configured with strong passwords. We will also ensure that default user accounts created during installation are disabled.

User Accounts & Privilege Level Check

A privileged user account has unlimited permissions to systems or data stored on a network. A person with a privileged account is in a position to make changes to system configuration, read / modify sensitive data and grant access to business critical areas to other users (including create additional accounts). A privileged account within an organisation fall under the following types:

  • Domain administrator
  • Local administrator
  • Service accounts
  • Business privileged user accounts

Build review would identify list of user accounts and their privilelges, making the business aware of the threat a server is exposed to.
