Q&A: How to Think Smarter About Database Security

New laws across the world are placing the spotlight on data security and privacy. Here in the Asia-Pacific region, for example, organizations are grappling with several measures, including Australia's Privacy Amendment (Notifiable Data Breaches) Bill 2016, the Philippines' Data Privacy Act of 2012, and Singapore's Computer Misuse and Cybersecurity Act.

The need to ensure compliance and remove risk has never been greater. I asked our expert Raul Gutierrez, principal global security architect at Trustwave, how you can work to better protect critical corporate data.


JB: Why are security specialists starting to look to secure their databases further? 

RG: When I talk to clients, they generally convey three main reasons why they need to explore additional protections for their databases and big data stores.

1) The relentless wave of attacks via phishing, spam and ransomware.

Adversaries use these methods to gain access to valid login details. Regardless of how locked down your database is, how far it resides behind the firewall and what intrusion prevention system you have in place, once the hacker has a valid user credentials, all bets are off.

2) The proliferation of cloud, mobile and shadow IT systems.

These create new databases in new locations that may or may not be at the latest patch levels, or even adhere to the organization's database security policies. The IT landscape within businesses is undergoing constant change, and it's hard for database administrators (DBAs), risk managers and security architects to maintain an adequate posture.

3) Data breaches.

Heard about them? They are not so unusual. Considering misused privileges play a role in most breaches, organizations must properly manage privileged users and the collection of additional privileges over time. The impetus now is to establish the "principle of least privilege" to get the job done - and enforce it continuously.


JB: What do you see as the main database security challenge for organizations? 

RG: The people! The database developer is writing documentation and code. The DBA is being asked to facilitate new applications - like giving access to data via mobile apps. (If they don't, they may be perceived as constraining access and stifling innovation). The internal audit guy or gal has a responsibility to validate segregation of duties and uncover exposure quickly.The governance and risk team, meanwhile, is wanting to satisfy the CIO and the board that they're not at risk of becoming a news headline. And then, of course, are the users who are requesting and requiring access to systems and data. There are a lot of moving parts, and it can be difficult to align everyone, especially in resource-deprived organizations. All these roles must work together to secure critical information.



JB: How can organizations assess what their current level of exposure is? 

RG: Use what the professional inspectors use. Many external auditors turn to database security scanners to discover, assess and report on the security, risk, or compliance posture of databases and big data stores. The report generated will identify vulnerabilities, configuration issues, weak passwords, patching shortfalls, access control problems and other deficiencies that can lead to user privilege escalation. Then, to scale this set of scans, organizations generally look to a more robust security platform designed for consistent monitoring and management of enterprise databases within the data center. This type of solution can help you enforce separation of duties and allow you to schedule, set and run and alerts regularly.


JB: Why would an organization need both database vulnerability scanning and activity monitoring? 

RG: Continuous scanning is essential to establish compliance for all database instances. More importantly, continuous monitoring will ensure you have a handle on who's accessing the data and if the request is reasonable. A solution that accomplishes the latter helps identify and alerts on unusual or suspicious behavior to help correlate with other network events. These alerts can be integrated with an organization's existing security management, risk mitigation and compliance environment. If needed, you can also activate immediate locking and termination functions when malicious activity is detected. I have seen organizations use this to provide continuous situational awareness of their database security posture without any manual assessments or expert review needed. It has significantly reduced the resource burden on the IT security and DBA infrastructure teams.
