A Question of When, not If

By Ray Rothrock, CEO, RedSeal Networks

Breached!  This is the new watchword in the executive office suite these days.  Ever since Brian Krebs revealed to the world that Target had been breached, every company is on notice.   While the primary role of the CEO is revenue and growth, there are a host of other activities that support revenue and growth.  Namely, the company’s employees and its data infrastructure are critically important for every company.  But what about the network?

Having been an investor in network infrastructure for a couple of decades, I know chances are very high that your company’s network has been built over decades, by scores of people of varying skill levels.  Chances are your network is very complex, beyond what any person or team can truly understand.  Chances are your network runs your business more than you really appreciate, and without it your business would stop.  It’s just as important as your manufacturing and supply chain, or your service centers, or your employees.  The network is a strategic asset of the corporation.

This was brotemp1ught home in a powerful way when I recently attended a cyber security meeting in London.  In addition to briefings with a number of industry analysts, this meeting also included a panel discussion with about 15 CISOs from various industries like finance, not-for-profit, publishing, media, banking, and manufacturing.  To a person these CISOs said two things.  First, their greatest need was skilled personal to run their networks.  Second, their senior management was asking questions about not “if” they were breached but what they would do “when” they were breached.  This shift in attitude, driven by all the news in recent years about breaches at large, household-name companies, was an “ah ha” moment for me.

Your company will be breached, or you will fall victim to some other network crime.  As CEO, you must prepare yourself for these events.  A lot can be done to prevent most breaches, and to be prepared when one inevitably does happen.  It starts by knowing just how your network is built and operated.  As trite a statement as it is, the truth of the matter is this:  If you don’t know how your network is built, how can you possibly secure it?

Have you asked your CISO what the plan of action is when a cyber attack is successful?  Does your board understand the liability of a successful attack?  Regrettably, it is a matter of when, not if.

Project Zero – A Smarter Way Forward

By Dr. Mike Lloyd

Google’s move to set up Project Zero is very welcome.  The infrastructure on which we run our businesses and our lives is showing green arrowits fragile nature as each new, successful attack is disclosed.  Unfortunately, we all share significant risks, not least because IT tends towards “monoculture”, with only a few major pieces of hardware and software being used most of the time.  Organizations use the common equipment because it’s cheaper, because it’s better understood by staff, and because we all tend to do what we see our neighbors doing.  These upsides come at a cost, though – it means attackers can find a single defect, and it can open thousands or even millions of doors, as we recently saw with Heartbleed.  This situation isn’t likely to change soon, so it’s welcome news whenever there are more eyes on the problem, trying to find and disclose defects before attackers do.

Attacks proliferate rapidly – very rapidly, in a quite robust market for newly found, highly effective vulnerabilities.  As they do so, it has become crystal clear that traditional passive, reactive methods of defense are insufficient. Google’s investment underscores the critical importance of proactive analysis of potential attack vectors. Any organization that is not developing a set of defenses from proactive analysis through reactive defenses is leaving the door open to attacks. Defenders need ways to automate – to pick up all the discoveries as they are found by the “good guys”, so they can assess their own risk and keep up with remediation. Recent incidents like Code Spaces and Target make clear that the health of enterprises and the careers of their executives are at stake; just expecting defenses to hold without some way to automate validation is not tenable.  Hope is not a strategy.

Your Security Has Been Compromised

By Steve Hultquist

On an autumn day in 2008 while I was an active, practicing journalist, I sat in my office and interviewed Todd Davis, CEO of LifeLock for my article on scanning the underbelly of the web. Todd is perhaps best known for appearing in ubiquitous advertising and broadcasting his Social Security Number. At the time, it was becoming clear that online threats to identity theft were growing dramatically, and they were introducing their new service to help their customers avoid appropriation of their identity online.

chessWe’ve come a long way since then. So far, in fact, that the NSA has change their strategy in a way that should send a shiver down the back of everyone responsible for enterprise security: They have switched to assuming that security has been compromised.

Let that settle for a moment. The NSA, the organization most responsible for understanding the cyber-security stance of the United States, its allies, and other countries and organizations worldwide has changed its approach to an assumption of breach.

As I noted in Inside the Mind of an Attacker and Inside the Mind of an Attacker (Pt 2), the motivation and environment of attackers has changed. Now, those with the greatest amount of information are agreeing that the situation has shifted.

With more than 100 foreign intelligence agencies targeting assets plus a likely greater number of criminal organizations, you need to decide how you are going to defend against this new environment. What tools and approach will you use once you recognize that evil actors are in your network? What does defense mean with this mindset?

What’s your answer?

Driving Blindfolded

By Dr. Mike Lloyd

I recently wrote about the necessity of getting the right data for security analytics.  But I’m continuously reminded how typical organizations lack an even roughly complete understanding of their network, or even a map of it.  I can understand why this happens – entropy is just as inevitable for organizations as it is in Physics.  Records don’t just keep themselves – networks change, and ideally it’s all planned and well controlled, but in practice, emergencies happen, corners get rounded off, triage goes on, and perfect record keeping is lost.  I know organizations who aim to have very strong processes, control, and accountability, and while I commend them for it, I find that if I look at their data, I still find enough gaps and unknowns to be a worry.  Sure, the mature organizations do better – they don’t tend to have records in the moral equivalent of a shoe-box under the bed (but I see enough of those). But the records still don’t add up.

driving_blindfoldedI think what worries me more are the organizations who know they have information gaps, but don’t treat them as a priority.  I see this as driving a car while blindfolded.  How is security possibly going to be effective if you can’t map out the infrastructure – the whole infrastructure, warts, labs, virtualization and all – and just look at it, let alone ask decent, proactive questions about how to defend yourself?  Imagine physical security – for example, badge reader installation – without having a map of the building, or even a vague idea of the number of doors that need to be secured.

Of course, I’m preaching to the choir – anyone reading this blog probably already understands that this is important.  I sometimes wonder if the real challenges are political, not technical or intellectual.  When a security team can’t get the blueprints to the network, what exactly is going on?  Is it overload?  Is it lack of people to go hunt down what’s missing?  Or is it the classic challenge of “nagging for a living”?  Many security teams I meet don’t have direct access to the network assets that are critical to defensive posture.  This means they have to ask, or beg, or cajole the NetOps team into providing data.  The strength of that team-to-team relationship seems to be a really important issue.  I’ve seen organizations vary hugely in speed and success with data analytics, depending on whether someone in Team Security has a buddy in Team Networking or not.  Perhaps the worst cases I’ve seen involve outsourced IT and networking – then it can get to levels nothing short of passive-aggressive.

Inside the Mind of an Attacker – Part 2

By Steve Hultquist

Recently, on a rainy Colorado afternoon, I sat down at my kitchen table to decide how I was going to upgrade our home security system. Just as anyone who has gone through this process would do, I walked around the house and looked at all of the possible ways an intruder could attempt to enter. I thought like an attacker, and determined how I would defend against any attempt to gain access.

This is how all physical security defense is done: analyze all possible access paths and put defenses into place at each one: locks, sensors, access codes, lights, and other approaches combine to create a defensive shield.

While this approach is obvious for physical defense, it’s rarely employed in defense of enterprise systems and networks. Instead, redrobotmany organizations rely on the equivalent of a guard sitting at one entrance expecting to see all access attempts when there are other doors to breach and a back fence that can be scaled.

One of the reasons for this approach is the incredible complexity of even the most basic enterprise network. With dozens to tens of thousands of extremely complex devices interconnected in an entwined web of cables and wireless meshes, it is, quite literally, impossible for humans to parse much less accurately understand and manage. You need systems to do it for you.

Much like home automation is coming into the mainstream with both Google and Apple offering integrated means for monitoring and managing everything from temperature and lights to locks and door status, automation for networks to be sure that your network is configured the way you expect and doing it the way you want it to be done is mission critical.

Data, Data Everywhere, nor Any Time to Think

By Dr. Mike Lloyd

I remember when I first started trying to solve network security problems, using fancy network analytics.  I applied the classic suspension of disbelief that’s necessary to work on any emerging technology – first, you assume all the hard problems will be easy, and second, you assume the impossible ones will just go away.  Happily, much of this is true – it’s funny how well it works.  Only later do you learn which problems are the truly hard ones.

What’s hard about network security analytics?  Well, not the security, and not the analytics – we’ve found we can do plenty on both of those that pays off really well, given the data.  The pesky data, now that’s a different kettle of enchiladas.

data everywhereAt first, I didn’t want to talk about data gaps – that sounded like a challenge to good analytics.  I was half right.  Eventually, enough CISO’s got it through my skull that uncovering data gaps may be pointing to reasons why analytics will be held back, but it’s also major value, in and of itself.  I was being dense – if we try to analyze security data, and we find it’s got holes in it, well, this means the security team didn’t know what was going on to start with!  Turning up these gaps is one of those inconvenient truths.  These days we’ve gotten pretty good at it.

But then what?  Typical security organizations are drowning in data, so how can I complain about needing more?  Well, facts are just facts; useful information, or better yet, actionable intelligence is something else altogether.  We stockpile data from sensors, but we struggle to find useful signal in there.  We deploy automated signal reduction engines, but they just turn mountains of alerts into hills of alerts, and we still don’t have time or people enough to climb those.  And along come these network security analytics people saying “what you need is more data”.  Hmmm.

Of course, what we need is the RIGHT data, processed the right way, at the right time.

Inside the mind of an attacker

By Steve Hultquist

This morning, I woke up, walked downstairs, and performed my morning rituals, including a review of OmniFocus on my iPad to see what was on tap for today. I looked at my list of projects, my next actions, and those items that are due in the next few days. Then, I went to work.

In many homes across the world, days began in similar fashion. Some of those reviewing their projects, however, had a decidedly different thematic thread: their projects have the goals of breaking into the networks and servers of key government and industry organizations for purposes of espionage, theft, or disruption. And they get paid to do it.

Some of us remember the earliest days of the Internet when servers were open to all. In fact, anyone could log onto the root account at Richard Stallman’s server and create their own personal account. My, how far we’ve come when breaking into networks and systems is a career path!

In the early days of people breaking into systems and networks, most actors were solo and focused on showing their own skills while demonstrating the weakness of those they attacked. Early viruses and worms (like the Morris Worm) were often the result of bugs in the target systems and mistakes in the attacking code.

hackerToday, governments across the world are applying their resources investing in full-time staff to break into systems and networks in other parts of the world. From the Syrian Electronic Army to the People’s Army, the US Government, and organized crime, attacks come from many different sources looking for a variety of results. This means the mentality is professional, organized, and coordinated, and the attackers are motivated by a variety of results, from financial to patriotic.

Knowing this, it’s essential that you determine the best way for you to defend against these attackers. They aren’t going to give up, so you need to be diligent and focused on your defenses. And we’ll talk more about that next time.
