Auditing Databases with Nessus
As a companion to another post on hardening network devices and creating baseline configurations, I wanted to look at another area where standardizing configurations can pay off in a big way. While there is plenty of fertile ground out there, I decided to focus on some specific aspects of databases. As I started reviewing recent research, I noticed a couple of interesting things from the world of finance that likely aren’t radically different from most environments. Findings ...

Maintain Your &%$#* Systems! A Mantra for IT Professionals in the Wake of Equifax
Once again, we have a basic failure in cyber hygiene causing a massive data breach. This one affects potentially half of the U.S. population and compromises particularly sensitive personal information that can be used by criminals to wreak havoc on people’s bank accounts, credit scores and identities. I’m referring, of course, to the Equifax breach. What I find particularly disturbing is that criminals took advantage of a known vulnerability for which a patch had been av ...
A Call for Congress to Prioritize Modernizing Government Technology
While we’ve already seen Congress engage in fierce debates over fiscal year 2018 funding, it’s important to remember that there are bipartisan issues on the table. Upgrading and modernizing government IT systems is one such area that deserves continued focus. That’s why we were pleased to see the Senate pass the 2017 National Defense Authorization Act (NDAA) with the Modernizing Government Technology (MGT) Act as an amendment from Sens. Jerry Moran (R-KS) and Tom Udall (D-NM). ...

Is DevOps the Best Thing to Ever Happen to Security?
Many of us have heard this story before, and it goes something like this: Developers are focused on one thing and one thing only - speed. They expunge anything that gets in their way or slows them down. And they can, because successful DevOps is becoming a core competitive differentiator for many organizations. Security leaders are focused on one thing and one thing only - risk. They are vigilant with ensuring compliance with enterprise policy and abhor change. And they can, because major cyber ...
Protecting Your Bluetooth Devices from BlueBorne
A new attack vector, codenamed BlueBorne, can potentially affect all devices with Bluetooth capabilities – ordinary computers, mobile phones, and IoT devices – literally billions of devices in the world today. Hackers can use this attack vector to leverage Bluetooth connections to completely take over targeted devices. BlueBorne spreads through the air, allowing it to bypass all security measures and potentially infect even “air-gapped” networks. The attack does not requ ...
