Critical Manufacturing Cyber Security Defense Program – A Starting Look

Cyber security professionals  are often tasked with trying to defend more than they have the resources to defend. This is especially true in the area of Critical Manufacturing as there tends to be a strong desire to protect everything.  In many cases when we try to protect everything we end up protecting nothing.  A Cyber Security Defense Program (CSDP) needs to be very focused and strategically deployed to protect the systems and areas which need protected.

Critical Manufacturing as defined by the Department of Homeland Security(DHS) is primary metal, machinery, medical, electrical and transportation.   Primary metal is Iron, Steel, Aluminum non-Feros metals;  medical includes facilities and devices, machinery is engines, turbines and power transmission, within electrical is electrical equipment manufacturing, transportation is :  vehicle, aviation and aerospace parts and vehicle manufacturing and railroad rolling stock.   Products made by these are essential to critical infrastructure sectors. The Critical Manufacturing sector focuses identification, assessment, prioritization and protection of nationally significant manufacturing industries within the given sector that may be susceptible to manmade or natural disasters.  This area is one that is critically in need of a strong CSDP.   The discipline for CSDP must not be twisted to taint what should be a strategic approach to the industrial base (“Critical Capabilities At Risk,” 2009).

One critical component to the protection of a Critical Manufacturing environment is that of using next generation, aka smart, firewalls with intrusion prevention and with some form  of malware  prevention and detection, updated via global feeds, enabled. This firewall environment should be set up in such a way as to segment the Critical Manufacturing infrastructure. Each individual plant or factory within the Critical Manufacturing environment should be on their own local area network (LAN) segment. A very basic way of thinking about this is captured in Figure 1 below.

Manufacturing Network Segmentation

Figure 1

Because of the method in which business decisions are made for factory systems it is critical that organizations involved in Critical Manufacturing use strongly firewalled network segmentation methods to ensure that each of their factory sites sit behind their own firewalls and on their own network segment (DHS, 2009).  This allows better control of the environment and enables the isolation of one factory without impacting the rest of the factories owned by the organization.  In this way if one factory is compromised by a hacker or group of hackers it can be removed and isolated from the organization’s global IT infrastructure.  Network segmentation, also called Network Control (NC) is a primary bastion for a defense in depth strategy and it can also be used to help prevent a blackhat from pivoting from a relatively unsecure factory system to a core business system.  Combining an Intrusion Prevention Appliance (IPS) or functionality with the firewall inside of a network segment provides a strong front line of perimeter defense for factories involved in Critical Manufacturing.  These IPS’ do not have to be overly tweaked and analyzed to be effective, running them in default signature mode is an adequate layer of defense for the network segment protecting and controlling a factory environment (DHS, 2009).

The Highest Risk Ever….. Not!

 

BlogWordleI just received one of my daily news reports about Cyber Security and it said something to the effect of such and such a Research group has found out that Application Security holes are at highest numbers ever and this number is expected to increase even further in 2016!  Companies really need to focus on fixing the risk incurred by these applications.  I thought, “Wow, Really”?  I mean yet another highest number, highest risk, most vulnerable, more danger than ever before message.  What a surprise it was to get yet another news feed about a Cyber Security vulnerability being the worst ever.  (that last sentence is dripping with sarcasm – just in case you couldn’t tell).   I really just want to shout and scream out that No It Isn’t the highest total ever!  None of these items being touted as worst ever are really the worst ever.  The simple reality is that we are still in our relative infancy when it comes to Cyber Security as a profession and as something to write about.  Being in our infancy means that we are still finding lots of this things that we couldn’t find before.

None of these vulnerabilities appeared overnight.  The vulnerabilities that we are now finding and that are generating these, at times horrific, Blog- Overnightreports about numbers of vulnerabilities have always been there.  Not only have these vulnerabilities been there but here is a secret I will let you in on – there are many more that we still haven’t discovered!  Companies, researchers, etc. now have the proper tools to discover concerning Cyber Security  vulnerabilities in large numbers.  These are items that in the past no one knew about even though they were there.  As more and better tools come out we will find even more of the worst vulnerabilities ever.

Vulnerable OS, vulnerable Webpages, vulnerable coding, vulnerable hardware or firmware,  these items have been around for decades and will remain around.  So while it is great that we can now find these and do something about fixing and remediation of these vulnerabilities they aren’t new.  Maybe newly discovered or newly recognized but they have always been there.   

Why am I going on about something that is basically hype, and in some ways good in that it publicizes exposure to these items so that Cyber Security professionals can use them to raise awareness, funding and support for remediation?  Because of the way the reports and news articles are written.  In too many cases these articles raise awareness and hype of issues that are much lower risk than the ones the organization’s Information Security team are already working on.  I have sat in many meetings where executive management has looked at the Chief Information Security Officer (CISO) and said “I know your team is really busy remediating core vulnerabilities across our Financial landscape but I read something yesterday about mobile devices being very vulnerable and I think we need to re-focus our resources….  the article really made this mobile risk sound like the most dangerous thing ever.”  

Don’t get me wrong,  I appreciate the awareness being generated but …. the WORST EVER …. no in most cases it really isn’t.  There are lots of Cyber Security items just as bad or worse that most organizations need to fix and the decision on where the highest Information Security risk sits inside of the company should not be decided by reporters and vendors but should rest on the shoulders of the CISO and the experts they have hired to analyze and determine what risk items need immediate attention.

 

Your Horse Was Analog

Your Horse Was Analog

Kevin L. McLaughlin

A  speech I made to 350+ people at the Michigan joint Military Ball.  Amway Grand Plaza Hotel.

Like my tie? My wife didn’t – gave me a lot of grief before we left the house,  you know how difficult things can be when your significant other doesn’t approve of your choice in clothing.

Well you see this tie has snoopy, the moon, the space shuttle and Apollo craft on it and it was given to me by Fred Hayes, yes the Apollo 13 Fred Hayes , yes astronauts are pretty neat people,  anyways Fred gave this to me when we were working on a project together and he told me that whenever I wore this tie I could look down at the pictures and that no matter what I do in the life I should remember that if we put a man on the moon we can do anything as a country.

…. as a country we can do anything,  even figure out how to defeat this cyber threat.

I want to change that thought just a little bit because I know what type of people went to and walked on the moon –  as a whole the U.S. Military and its veterans can do anything   make no mistake we are under attack, not by conventional weapon systems like guns and missiles but by cyber warriors utilizing digital attack vectors.

My speech tonight will be about trust and how it will help us win our cyber battle.  But, before I start I would like to do a shameless plug for the Whirlpool Veterans Association, who mentors soldiers transitioning to the private sector and with multiple outreach programs – I am sure many of the companies you work for have similar programs and a big thank you to those as well.

Trust and authority will be tonight’s theme. A lot of Information Security Professionals left Home Depot after years of not having their voices heard and repeatedly being over-ridden about whether a system could be touched or not.  Many Board of Directors are asking how to fix the cyber issue  –  a lot of the CIO’s and some of the CISO’s when asked that question are taking a passive posture of saying that their job is to make them aware of the risk versus telling them what to do.  In my opinion that is not the right answer… the people who are trained in cyber defense need to drive answers and solutions not just show risks

I will admit though that this morning while I was working out I had a big moment of angst,  you see I am an expert in this field and I can have an opinion and if I get it wrong a company will lose money but you know – if you get it wrong  lives will be lost and in the worst case our Homeland can fall.  Even with that – tonight you will hear what I feel we need to do in order to start winning the cyber battle.  We got our butts kicked by the bad guys in 2014 and it was a loud wake up call to anyone paying attention that what we have been doing is not the answer.

The general theme throughout my speech tonight will be one of trust. High performing teams consist of players that trust each other and who understand that each of the team members has an area that they are the expert in.  We cannot continue to ignore or muffle the voices of our highly trained and skilled cyber defenders and expect to be successful in our cyber defense efforts.

One of the first things we need to understand is that there is always in existance a large understanding gap.  I got my first taste of this type of understanding gap when I returned from Basic Training and I was talking to my Grandpa.  He asked me where I was stationed and I said Fort Bliss Texas,  he asked me what units were stationed there and I said the 3rd Cavalry. He got excited and we started talking;  about 5 minutes into the conversation it dawned on me that he was talking horses and I was talking tanks.  He was talking analog.

You see, we continue to increase our combat effectiveness by implementing new tools and technologies the majority of which are not analog, but are instead digital.  Digital means that they present entirely different attack vectors and will require us to have an entirely different level of trust in the expertise of the cyber defenders we put in place.  We must protect our digital assets.

The current generation of service men and woman are some of the first who have known nothing but digital tools.

(I left out this next part due to time constraints)

[Did anyone see the movie BattleShip? It’s a bit of a cheesy movie but there is a part in it where the modern digital destroyer gets blown up and the only available ship to fight the aliens was a WW II BattleShip,  they are working to try and figure out how to use the ship and the Chief looks at the Ensign and says “sir, this old thing is completely analog, it will take us years of reading the manuals to learn how to float and fight it”.  All of a sudden a long line of navy veterans come walking up and they are able to work side by side to show the team how to run and fight the ship –  think about this – in another 10 to 15 years people who understand analog are not going to be around to help us out.  ]

I continued my speech here —    I have to wonder how many of these digital troops would use a smartphone or GPS, even if disallowed in the mission parameters,  if they get lost during training?  I’m not disparaging anyone, I just realize how very hard it would be for any level of team leader to stop themselves from using an alternative before calling into command and telling someone that they were lost.  We all know how difficult that radio call would be to make.

What is scary is that if these digital devices were suddenly taken away our combat effectiveness would be greatly impacted – maybe by 90% or greater.  Ok,  each of your digital devices, smartphones, etc. have just been reset to 0:00 – how many of you can tell me what time it is?  Show of hands  {note – out of 350+ people in attendance only 2-3 raised their hands} wow, that was actually far worse than I expected it was going to be.

Having these digital items give us a significant advantage but also put us at risk if we don’t adequately protect them from cyber attack.  Tanks, Planes and ships will not operate if their computer systems are taken off-line.  Year after year we see annual reports that tell us  that our military systems are in no better shape than private sector systems are and our military IT staff feels the same pressures to get systems in place quickly rather than securely – we must be better than that. {looked down at tie and lifted it up}  We can do anything….

Most of us Cybersecurity professionals (risk professionals, assurance, etc. ) are very passionate about what we do – I personally spend upwards of 30-40 extra hours each week staying current, learning, wargaming, gathering intelligence, figuring out business enabling security strategies, and more.

How many of you in this room (Cybersecurity men and women you are not allowed to answer) can say you spend that much time studying and focusing on cybersecurity? How many of you even spend 2 hours per week?  Of course you don’t spend time studying Cybersecurity nor should you – that’s why you put cyber security professionals on your team.

Then why is it that across Corporate America, and I can only imagine it is a bit worse in the military, is it so hard to build trust between the Cyber defenders and the management community of the organization?  I know some of you are sitting out there thinking -What’s this guy talking about – I trust my Cybersecurity person.  Do you?  Do you really?

Think about this … you are the Colonel in charge of finance imagine an E6 Cyber defender walking into your office at month end closure and telling you that he has to take one of your business critical system off-line immediately for security patching as it is critically exposed and can be very easily compromised which could put the rest of our infrastructure at risk. He then tells you that the outage may last 8 to 10 hours.    Well, after 17 years experience as a security professional in Corporate America I can tell you that this request would be met with a lot of resistance and most likely the Cyber Defender will be told to wait for a day or two to do the patching.   Often times that directive will come with a comment about “you security guys and girls don’t really understand the business and tend to over-react”….

Hmmm…  I can only imagine similar conversations happening inside of Target, HomeDepot, Sony, Subway, Dairy Queen, Sigh, I’m not going to name them all – but like I said earlier we really got our butts kicked in 2014.  2015 continues the theme with the Anthem breach – a breach which directly impacts each one of you the Feds feel China committed the breach to continue their mission of gathering the personal data of our active and former military and their dependents.  We don’t know what they want the data for but it is obvious that they want it

Trust,  Target has a 148 million reasons – those are dollars by the way – plus open lawsuits, HomeDepot has 120 million reasons and Sony has 1 billion reasons, to implement a Cyber Defender authority policy.   1 billion?  how many of you work for companies that would even be able to survive a 1 billion dollar loss? I imagine if I lost a billion dollars for a company I’d be out on the street. and luckily for us we are starting to see Board Chairman, CEOs and CIOs resigning due to allowing a security breach to occur on their watch. Why is that lucky?  because it might raise the awareness we need to help fix this issue.

A base level of trust needs to be in place that makes it so that is assumed your cyber defender, who also is part of your profit sharing plan and wants the company to make money or who is a strong patriot and wants our tanks to run or planes to fly,  is not going to willy-nilly.  I just wanted to say willy-nilly in a formal speech,  is not going to willy-nilly take systems off-line and that when they say a system really needs to be fixed immediately they need to be granted the authority, we already give them the responsibility and career risk when a breach occurs,  now let’s give them the authority they need to protect the organization,  even if there is a small short term negative profit impact – wow that is hard to say but I bet if we asked Target, HomeDepot, Sony, Anthem, you get the idea if they could go back in time and accept a $5,000.00 profit hit in order to take a system off-line and patch it instead the breach they would all say yes.

For you the risk of allowing the E7, E8, Lt. Captain, Major, etcetera, I’d try to go on but I’ve been out of the military for a loooong time and would most likely get the other command ranks wrong…   to trump the cyber defender may just result in a significant loss to both your combat effectiveness and your ability to defend our country.

Trust,  trust the cyber defense experts that we are graduating from our military schools to both understand the business and to effectively assess the risk and make the call on fixing open and exploitable channels of attack.  While the department heads and commanders should still have the final say an answer of “don’t touch this system” or an answer of “you are over-reacting to this threat  – yet how would they even have the expertise to make that judgment?  should be the rare exception and not the norm.       – Trust and authority-   we can win this cyber war and defend our systems against the cyber threat.

Home Depot Breach 43M loss posting on LinkedIn

I just read an article on LinkedIn about the negative impact caused by the recent Home Depot breach. Here are my thoughts about how all the 2014 breaches should change some C level and Information Security paradigms. These could cause a major C suite thought shift and maybe even a large paradigm thought shift in how our profession thinks about the skills and talents really needed by Information Security professionals.

Note – I know this opinion will not resonate well with some CISO’s – Major IT departments continue to hire CISO’s that have little to no security background. Hackers and blackhats are associated with organized crime and IMO until we put more of an emphasis on the word SECURITY in the CISO title and until CISOs stop walking a tightrope by always trying to compromise and keep the business happy by letting the business need trump the security need (“ok, don’t patch that extremely vulnerable system I understand your business need not to” ) the crooks will continue to win.

Also, it appears that too many companies are basing their CISO hiring decisions on the candidate’s business acumen. Wouldn’t it be better to focus on how well the candidate knows how to fight and deter criminals?
I’m not saying CISO’s don’t need to understand the business I am saying that a stronger focus should be on how much the CISO knows about criminals and crime fighting. I also realize that thought would take a major paradigm shift in the thinking of the C suite.

Just a Random Thought After an Information Technology (IT) Meeting

It is not the job of IT operational support staff to eliminate 100% of failures across the corporate infrastructure. (cost would be too high) It is ITs job to manage failures so that they stay within the levels of operation the business has determined as acceptable.  – Kevin McLaughlin

The Cyber Security CIA explained via Calvin and Hobbes

Leave it to my son Kody, who is starting his Cyber Security career to come up with this novel way to explain the CIA triad for Cyber Security.

In InfoSec terms, CIA refers to Confidentiality, Integrity, and Availability. To illustrate how these principles work, let’s look at Calvin and Hobbes.

Calvin and Hobbes create a club called the “Super-Secret-No-Icky-Girls-Allowed” club. During their very first treehouse meeting, they draft a document entitled “member list” and write the names “Calvin” and “Hobbes” on the list. This list is the club’s most valuable asset so Calvin and Hobbes need to maintain the CIA of the asset. The confidentiality of the list is critical as the exposure of the secret member list would cause the entire super-secret club to lose its purpose. The integrity of the list is also important to ensure that unauthorized modifications of the list can’t be made. It would be terrible if Susie’s name were to make it on the list of if Calvin’s name were to be removed. Lastly, the availability of the list is important. When the club meets to have their secret meetings, they need the list do roll call and to ensure that those in attendance are listed.

So now that we’ve got the idea, we can explain how CIA works for business assets. The confidentiality of the asset is necessary to ensure that only those with appropriate privileges and appropriate need can see the asset. The integrity of the asset is necessary to ensure that the data has not been changed and, if it has, a log of changes is kept. The availability of the asset is necessary because it is not of any value if no one can interact with it for its intended purpose.

Compliance does not Equal Security

When I read items like this:

Agarwal said NoMoreRack is now in the process of certifying itself this time as a Tier-1 merchant, even though the number of credit and debit cards it processed in 2013 placed it squarely in the Tier-2 range.

I get frustrated.  While I understand that Compliance is necessary and is important companies still need to understand that being compliant does not mean you are secure! There is more to it than that.  In too many cases Compliance is just a check box that makes senior management feel better about the overall state of organizational security.

Why Is It?

Why is it that Internet Crime statistics continue to show that for the criminally inclined internet crime is a very viable and fast growing field?

Why is it that millions of dollars are stolen from end users who simply fail to pay attention to the basics of Information Security like strong pass-phrases and “don’t click the link”?

Why is it that in March of 2010 there was a breach of University student’s personally identifiable information (PII) that numbered over 3.3 million identities being stolen?

Why is it that in 2012 there was a breach of over 6 million IDs from the state of South Carolina IT Infrastructure?

Why is it that online banking theft is at an all time high with thefts against mid size business and metropolitan areas taking center stage?

Why is it that even though unheard amounts of information is being stolen daily that non-cyber security professionals are still very vocal in explaining to experts in the field of cyber security why passwords, pass-phrases, encryption and other basic controls don’t work and are too cumbersome?

  •  Yet in most breach cases if basic information security controls and best practices like defense in depth would have been in place and followed the breach would not have occurred

Why is it that the non- Cyber Security professional’s opinions on what Cyber Security controls are important are often given more weight than the Cyber Security professional’s opinions within an organization?

Why is it that Senior IT and Business managers within an organization still won’t listen to the Cyber Security professionals they employ when it comes to building and maintaining an effective security and control infrastructure?

Why is it that Cyber Security professionals still don’t have the voice they need within most corporations (Government, Public and Private) to actually protect the organization’s data?

Why is it that blame for failure to protect corporate data is quick to be placed on the shoulders of Cyber Security professionals who weren’t listened to in the first place?

Why is it that as experts we really do have the knowledge and ability to protect sensitive corporate data but in most organizations we are not given the power to do so?

Why is it that rhetorical questions are not answered?
