Obama Stimulates Compliance Spend

from HIPAA.com:

A new requirement (one of the HITECH Act provisions of the American Recovery and Reinvestment Act (ARRA), signed by President Obama on February 17, 2009) will have business associates of covered entities required to comply with the Security Rule safeguard standards, beginning February 17, 2010.

from the article:
Covered entities are required to have in place audit controls to
monitor activity
on their electronic systems that contain or use electronic protected health information. In addition, they have to have a policy in place for regularly monitoring and reviewing of audit records to ensure that activity on those electronic systems is appropriate. Such activity would include, but is not limited to, logons and logoffs, file accesses, updates, edits, and any security incidents.

Monitoring and review of audit trails must be as close to real time as possible to be useful. There is no benefit in discovering a problem days or weeks after it has occurred. How a covered entity sets its policies and procedures will be based on outcomes of the covered entity’s risk analysis. If a security incident occurs, failure to exercise this audit control standard may be proof in an inquiry that a covered entity had the capability of knowing what was occurring, but failed to exercise timely corrective action.
(emphasis added)

Interesting. I need to track down the source docs to see what's real and what is interpretation.

The SOFT Insider Threat

I've written a lot about the insider threat and what it means to me. A while back, I spoke to IT Business Edge about my opinion that non-malicious insiders pose a greater risk of causing a breach than malicious insiders. Many in the industry still claim that insiders should not be a major cause for concern and that external threats should get the lion's share of attention.

It's fairly easy to see that malicious attacks cause immediate and expansive financial harm. But, the unintentional or at least non-malicious insider breaches, which I'll call the Soft Insider Threat, occurs far more often – perhaps hundreds of times every day.

Today, I read a story in NetworkWorld titled Inside a Data Leak Audit that illustrates my story.

The IT Director at a pharmaceutical firm facilitated a data leakage audit for his company. Before the audit, the firm believed they "were in good shape". They "had done internal and external audits" and "extensive penetration testing". They had intrusion detection and prevention solutions, laptop encryption, and employee training. What they found out is that "you can do all that and it's just not enough."

The audit, conducted by Networks Unlimited, revealed gaping holes, including:
  • 700 leaks of critical information, such as Social Security numbers, pricing, financial information and other sensitive data in violation of the PCI-DSS standards.
  • Over 4,000 incidents that ran counter to HIPAA and Defense Department Information Assurance Certification rules.
  • More than 1,000 cases of unencrypted password dissemination, such as to access personal, Web-based e-mail accounts.
A few specific examples:
  • Employees sent ZIP files and attachments of confidential documents in unencrypted emails.
  • An employee attached a clinical study report in an unencrypted email to an outside vendor.
  • An employee sent sensitive employee compensation data to an outside survey company inc. salary, bonuses, sales quota, stock options, granted share price and more.
This single audit conducted on one company revealed 11,000 potential leaks that not only went unreported as data breaches, but wouldn't have even been known about or identified as problematic if the audit wasn't going on at the time.

I call them soft breaches because they're not intended to be harmful and may not ever cause harm or get noticed. But if they happen 10,000 times over the course of two weeks, that's 260,000 security violations each year. And those are real breaches that may violate HIPAA or PCI-DSS, expose employee and customer information, violate business contracts, and otherwise cause potential for harm. It should be pretty apparent that if this happens 260,000 times each year, that's a pretty big attack surface.

As the author and auditor say in the article, don't leave security in the hands of end-users. Automate the important stuff and track activity on a regular basis to ensure that your attack-surface is in-line with your risk tolerance. Don't ignore the soft insider threat just because it gets overlooked. That's the exact reason why you need to address it.

Trust But Verify

Yesterday, I posted on The Value of Security Audit and Bruce Schneir's recent writings on the topic. Today, Richard Stiennon posted on the topic in an expansion of his three security laws.

He writes (abbreviated):

"...the first two rules could be simplified to 1. Don’t trust the network. 2. Don’t trust end points. But that level of simplicity does not transfer to people. You have to trust your users. So, borrowing from Ronald Reagan’s immortal words Trust but verify, you have to apply the following...

1. Strong authentication and granular access controls.
2. A published policy on acceptable use of resources.
3. A monitoring and alerting system that informs the user of policy violations."
He continues and suggests that making security achievable requires all three. The idea that monitoring and alerting is required has finally become mainstream. More and more smart people seem to be listing it as a necessary component of a secure environment.

..our little baby is all grown up (sniff).

Better data from Active Directory for your SIEM

If you Have or are Planning to Have:
  • A SIEM solution (ArcSight ESM, RSA enVision, Novell Sentinel, IBM TCIM)
  • An enterprise Log Management solution (LogLogic, TriGeo, SenSage)
And your employees log on to:
  • Microsoft Active Directory / Windows
  • Novell eDirectory / NetWare
And you're unhappy with the solution's ability to:
  • Get complete information from the directory or file system
  • Filter which information is collected
  • Generate highly relevant alerts based on filtered event data and custom policies
  • Collect event data directly from the source (independent of system logs)
  • Apply decisions or alerts based on WHO is performing the action
  • Report on ANY combination of objects and attributes in the directory
  • Report on who is opening or modifying files, folders, or file system permissions

THEN ...Please give us a call.

I recently wrote a paper discussing how we (NetVision) extend the ability of SIEM or log management solutions by getting better, more reliable, and more relevant information directly from what is arguably your most critical source (the network directory). The paper isn't publicly available (it's not that kind of paper). So, let us know and we'll pass it along or we can save you the trouble of reading and just explain it.

What to Monitor in Active Directory

If you manage an Active Directory infrastructure, you probably know that you should be monitoring activity or data or something. But what exactly needs to be monitored? Well, as I say in my latest paper, there is no one-size-fits-all prescription for Active Directory monitoring. But, there are five items that carry particular interest. In this paper, I go into detail on each of the five – what needs to be monitored and why.

For many mid-market organizations, these five may cover 80% of security monitoring needs – especially for organizations that are strategic about their use of Active Directory. As the title says, it's strictly limited to Active Directory, so don't look for firewall logs or changes to virus protection files. There's a short excerpt here if you'd like to take a peek.

If you're a security or Identity Management consultant, feel free to contact me directly and I'll be happy to send you a copy.
