HIPAA and the Standard of Due Care – How Much Security is Enough?

There’s a natural struggle between those who write rules around compliance to a standard and those who must implement IT systems to ensure compliance with that standard. The former want to create guidelines rather than hard and fast requirements so there’s flexibility in how to achieve compliance. Plus, they want guidelines that allow for advances in technology. The latter want technical specificity – do X and become compliant.

With a compliance standard like PCI DSS, which specifies credit card information security requirements, there’s a great deal of technical specificity about what is required in order to become PCI DSS compliant. In fact, all but a handful of PCI DSS’s 211 sub-requirements call for specific technical actions. But even then, some PCI DSS sub-requirements are subject to interpretation by the various auditing authorities.

Most compliance mandates, especially those imposed by governments, aren’t as cut and dried as PCI DSS and they always include many specific requirements around acceptable compliant behavior in addition to non-specific requirements around technology-oriented compliant safeguards.

The privacy and security of health information in the U.S. is governed by a Federal law called the Health Insurance Portability and Accountability Act (HIPAA). As written, HIPAA is vague in many behavioral and technological areas. The law turned over “rule-writing,” whose aim is to provide more specificity, to the U.S. Department of Health and Human Services (HHS). HHS wrote a key rule – the HIPAA Security Rule – that is relevant to information security professionals.

But alas, even the HIPAA Security Rule is ambiguous! Read More »

Attend the PCI Community Meeting and be Heard!

The Payment Card Industry (PCI) Security Standards Council (SSC) is an open global forum for the ongoing development, enhancement, storage, dissemination, and implementation of security standards for account data protection. According to the PCI SSC, 2012 is a critical year in the standards development process that hinges on feedback from the PCI community.

Getting the latest information about the PCI Data Security Standard (DSS) is vital as products and technologies continue to change at a rapid pace. Being part of the conversations, networking with like-minded professionals, and interacting directly with payment card brands are just a few of the benefits of attending the sixth annual PCI SSC North American Community Meeting. The meeting runs September 12—14, 2012 at the Walt Disney World Swan and Dolphin Resort in Orlando, Florida.

Oracle Java Zero Day Vulnerabilities Risks and Mitigations Part 2

In the previous Part 1 post, I discussed the initial response, risk, and mitigations for the recently-disclosed zero day Oracle Java vulnerabilities that attackers have used in attacks against vulnerable end-user systems. Since then, Oracle has released software updates that correct the original flaw documented in IntelliShield alert 26751, as well as for additional vulnerabilities, as documented in IntelliShield alert 26831.

Attacks leveraging the Java vulnerabilities have increased, with reports indicating that tens of thousands of systems have been compromised. The malicious software toolkit BlackHole, documented in IntelliShield alert 25108, has incorporated the previously-reported Metasploit exploit and can be used to build exploits for use in attacks. Observed exploits have installed the Poison Ivy remote access trojan, and other malicious software may also be downloaded and installed using Poison Ivy, once installed on a vulnerable system.

Targeted Attack, Targeted Response: Designing and Implementing an Incident Response Plan That Works

September 4, 2012 at 7:30 am PST

A few weeks ago I had the pleasure of participating, as a guest speaker, in a webinar titled “Targeted Attack, Targeted Response: Designing and Implementing an IR Plan That Works.” Joe Riggins, Senior Director of Incident Response for HBGary, moderated this Q&A format webinar. We discussed the current incident response (IR) challenges companies are facing, as well as specific steps organizations can take to design, test, and successfully implement an ongoing IR plan for their specific business environment.

The webinar recording can be accessed here.

Global Correlation: IPS + SIO = Greater Protection

The Cisco Intrusion Prevention System (IPS) includes Global Correlation capabilities that utilize real-world data from Cisco Security Intelligence Operations (SIO). We have seen on this blog before how IPS Global Correlation can be used to detect and validate the urgency of emergent threats as well as allow our team to hone the protection capabilities of our IPS Sensors.

Perhaps more fundamentally however, Global Correlation allows Cisco IPS Sensors to filter network traffic using the “reputation” of a packet’s source IP address. The reputation of an IP address is computed by Cisco SensorBase using the past actions of that IP address. IP reputation has been an effective means of predicting the trustworthiness of current and future behaviors from an IP address.

Our team has recently published a new white paper that explores the benefits of IPS Global Correlation and how they relate to various IPS deployment scenarios. I would like to share a couple of items from the white paper and encourage you to read it for more information.
