Top Ten Database Security Threats of 2015

Ranking Threat Brief Description Example 1 Excessive and Unused Privileges Database access privileges are granted

that exceed the requirements of their job function or there need to know, resulting in privileges abused

1

2 Privilege Abuse Abuse of legitimate privileges can be considered a database vulnerability, if the malicious user misuses their database access privileges.

2

3 Input Injection A class of attacks that rely on injecting data or code into an application in order to facilitate the execution or interpretation of malicious data in an unexpected manner (See also SQL Injection and Code Injection)

3

4 Malware Is malicious code to automate the exploitation of one or more known exploits; the principal purposes of those malicious agents are information stealing and sabotage.

4

5 Weak Audit Trail Automated recording of database transactions involving sensitive data should be part of any database deployment. Failure to collect detailed audit records of database activity represents a serious organizational risk on many levels.

5

6 Storage Media Exposure Backup storage media is often completely unprotected from attack. As a result, numerous security breaches have involved the theft of database backup disks and tapes

6

7 Exploitation of Vulnerabilities and Misconfigured Databases

Vulnerable and un-patched databases, or discover databases that still have default accounts and configuration parameters

7

8 Unmanaged Sensitive Data Companies struggle to maintain an accurate inventory of their databases and the critical data objects contained within them. Forgotten databases may contain sensitive information, and new databases can emerge

8

9 Denial of Service (DoS) Denial of Service (DoS) is a general attack category in which access to network applications or data is denied to intended users.

9


10 Limited Security Expertise and Education

Lack of expertise required to implement security controls, enforce policies, or conduct incident response processes.

10

The list of top ten database threat as identified by Iperva Application Defense Center. To read the White Paper published by Imperva go hear.

1) A bank employee whose job requires the ability to change only accountholder contact information may take advantage of excessive database privileges and increase the account balance of a colleague’s savings account. Further, when someone leaves an organization, often his or her access rights to sensitive data do not change. And, if these workers depart on bad terms, they can use their old privileges to steal high value data or inflict damage.

How do users end up with excessive privileges? Usually, it’s because privilege control mechanisms for job roles have not been well defined or maintained. As a result, users may be granted generic or default access privileges that far exceed their specific job requirements. This creates unnecessary risk.

Mitigation

• User Rights Management • Monitoring and Blocking • http://itsecurity.telelink.com/excessive-and-unused-privileges/

2) An example for that would be a database administrator accessing data that he/she has no “need to know”, e.g. the contents of the CreditCard table. This manifestation could also be an application problem, if the application allows an account specialist to access accounts not assigned to them.

Mitigation

• Do not grant unnecessary privileges • Follow the Least Privilege Principle • Best Practice Audit Trails (including account information) • http://sqlity.net/en/2542/privilege-abuse/

3) Examples of attacks within this class include Cross-Site Scripting (XSS), SQL Injection, Header Injection, Log Injection and Full Path Disclosure. The most common form of Injection Attack is the infamous SQL Injection attack. SQL Injections operate by injecting data into an application which is then used in SQL queries

Mitigation

http://itsecurity.telelink.com/excessive-and-unused-privileges/



• Apply the Defense In Depth principle. • Validation • Escaping • Parameterized Queries (Prepared Statements) • Enforce Least Privilege Principle • http://phpsecurity.readthedocs.org/en/latest/Injection-Attacks.html

4) In November 2012, Symantec published a security alert on a new malware dubbed W32.Narilam that was designed to damage corporate databases. The W32.Narilam worm attempts to spread by copying itself to all drives and certain shared folders on the victim’s PC. There weren’t instances that included a module to steal information from the victims. The worm was designed to attack SQL archives; it was able to search for database instances. Once the database instance was found, the malware was able to access database objects to manipulate them; it was also able to delete the entire archive.

Mitigation

• Physical and logical policies • Reactive and proactive approaches to malware and virus prevention • Strategies for helping to reduce malware • https://msdn.microsoft.com/en-us/library/cc875818.aspx

5) On September 18th 2014, Home Depot published a press release (pdf) about their recent data breach. In this document, they let us know, that the "cyber-attack is estimated to have put payment card information at risk for approximately 56 million unique payment cards". http://sqlity.net/en/2574/weak-audit-trail/

Mitigation

• Audit current security practices and applications. • Do research, including reading the whitepaper mentioned several times above provided by Imperva. • And lastly, resolve the issue of a weak audit trail now by investing in an independent data audit trail.
