Why CIOs May Be The Company’s Biggest Security Risk

Your actions may be inviting danger into the company

The world is a very dangerous place. Your IT department has lots and lots of data on its computers that bad people would like to get their hands on. Thank goodness your company has taken care to secure every way that there is for outsiders to get into your company’s network. Oh, wait a minute. Maybe there’s one way that hasn’t been secured – you!

What We Are Doing Wrong

Over the last 30 years or so, corporations have spent untold billions of dollars to create secure corporate networks. The definition of information technology tells us that we need to use firewalls to keep the bad guys out and strict corporate policies to restrict just exactly what can be connected to the corporate network.

That’s all fine and good until you, the CIO, comes along. For a couple of very important reasons you may be your company’s single greatest security threat. The first of these reasons is simply because you know too much. In your head is a lot of information that both hackers and your company’s IT sector competition would love to get their hands on.

This means that every action that you take online runs the risk of exposing confidential company information to the outside world. This could be as simple as when you update your LinkedIn profile with what you are currently working on to when you use your personal Gmail account while you are at work.

The second way that you may be your company’s biggest security threat is by your love of all that is new and shiny. CIOs are notorious for being the first kids on the block to go out and buy the latest tech gadget no matter if it’s the latest iPhone or iPad. Once you have this fantastic new device and you start to use it all the time, you’ll of course bring it into work. When you do this, you run all sorts of risks.

Hanging A Sign Out

If you were a bad guy and you wanted to break into your company’s corporate network, how would you go about doing it? Considering that companies have had enough time to secure their corporate networks from people breaking in from the outside, you’d probably do the next best thing: try to break in from the inside.

You’d go about doing this by finding out who worked for the company. Then you’d engage in a little of what’s called “spear phishing”. This is when you send someone who works for the company an email that looks like it is coming from somebody else inside the company asking for usernames, passwords, nuclear launch codes, etc.

We’ve all been trained to not respond to spam emails that we get all the time. However, these spear phishing ones are a lot harder to detect because they look like they are legit. We can become a phishing target by sharing a lot of personal information on the web. LinkedIn is a prime hunting ground for those would like to do us harm – there is a lot of key information shared out there.

Doing It Ourselves

Another way that we can cause great harm to the company is when we bring our newest and shiniest electronic gadget with us to work. As the Iranians found out with their centrifuge machines, a computer from home can contain all sorts of nasty viruses and bad things.

The company has polices about what can be connected to the corporate network and what public web sites we are allowed to use while at work. As CIO you may believe that these rules don’t apply to you; however, that’s where you’d be wrong. Yes, the rules might be an inconvenience sometimes, but they were created for a reason.

Couple all of the standard threats and then add in today’s popular social media sites and you have a real problem on your hands. The fact that hackers can reach out to you via numerous social media sites means that they are just that much closer to getting into your corporate network.

What We Need To Be Doing

So clearly it’s a big scary world out there and we are not immune from taking steps to be part of the solution, not the problem. What should we be doing?

First off, just make it a personal rule that you’ll never email any confidential information such as user names or passwords to anyone no matter if you think that they work for the company or not. If somebody needs that information, have them come to your office and pick it up.

Next, make it a policy to never open any attachments that have been added to an email that you’ve received. This is how the bad guys get you to run code that opens up doors into your corporate network for them. Make it a habit to not open any attachments until you get into a meeting or a call where the person who you think sent it to you can confirm that they really did.

What All Of This Means For You

So now that we understand that the single greatest threat to the safety of our company’s digital assets may be us, what does all of this mean? It’s actually pretty straightforward. We need to become more responsible in how we behave because of importance of information technology to our company.

We need to always be aware of the fact that there are people out there who are always looking for a way to break into our company’s computers. Due to our special position in the company, if we’re not careful then our actions may open a door for them to gain access to the company’s network.

I like the newest flashy device just as much as you do. However, when it comes to keeping the company’s network safe, it appears as though we need to separate our personal life (and devices) from those that we use at work. Don’t worry – eventually all good things will find their way into our office the right way!

What We’ll Be Talking About Next Time

One of the most important jobs that a CIO has to do is to manage the people that work for him or her. I’d like to be able to tell you that all of those people are going to be start performers. However, that’s not the case. Where a CIO can run into real problems is when some of the team are bad apples – lazy, angry, or just downright incompetent. What’s a CIO to do?

The Machines May Be Virtual, But The Security Problem Is Real

Virtual Machines Pose Real Security Threats

When you become CIO, you already know that IT security is going to be one of your biggest and least rewarding challenges. If you do a great job at it, then nobody will ever know and you’ll get no credit for it. If you do a poor job, then everyone will know and you’ll get all the blame. That just goes with the CIO job.

In the future, CIOs are going to have a whole new set of security issues that come along with the popularity of virtual machines. The rules for how best to secure these boxes that really aren’t boxes have not been established yet. What can you do to make yourself ready to take on this new challenge?

Just What Is A Virtual Machine?

Before we dive in and start talking about security, let’s make sure that we’re all onboard when it comes to just exactly what a virtual machine is. Awhile back, some very smart folks (a lot of who happened to work at a company called Vmware) realized that most companies were deploying one application per server in their data centers. One for email, one for web hosting, etc.

It turns out that as servers got more powerful, this was incredibly ineffective – most of the server’s processing power was not being used. The smart people created what they called a virtual machine (or VM) – software that sat on the server between the actual server hardware and the operating system that was running on the server. You can sorta think of it as a lower level operating system

Once this VM was in place, they discovered that they could run multiple operating systems (and then of course multiple applications on top of those operating systems) on each individual server. When they did this everything was isolated – if one operating system crashed, it didn’t interfere with the other operating systems / applications running on the same box.

As you can well imagine, this has turned out to be an incredibly popular way to reduce the number of servers that have to be deployed and maintained within a data center. However, it has also opened the door to some nasty security problems…

The Problem With Virtualization Security

Oh sure, you THINK that you know how to secure a data center – lock down all of the network ports going in and out, and then take steps to make sure that you know which staff are allowed to enter and leave. Oh oh, when your servers stop being real physical boxes and start to become virtual images, now you’ve going to have a whole new set of problems to deal with.

Cameron Sturdevant has been looking into just how we can go about securing the brave new future of virtual machines and he’s uncovered ten new issues that you are going to have to be able to deal with:

  1. Moving Too Fast: since virtual machines can be set up and put into operation much quicker than a real server can, you’re going to have to set up some sort of review process in order to keep things under control.
  2. Redefine Your Boundaries: it used to be simple to be able to keep the important things inside the data center and the threats outside when everything needed a physical box. Now that things are going virtual, these boundaries are getting more murky and you will have to spend the time to redraw them.
  3. Killed By Quantity: since it’s so easy to set up a new virtual machine, you’re going to be facing an explosion of them. This means that you’re going to have to establish a policy to determine when a new virtual machine needs to be deployed and when it needs to be turned off.
  4. Moving Day Is Everyday: since virtual machines can easily move from box to box, you’re going to have to lay down the law in order to make sure that the new server has the appropriate security policies in place in order to support the applications that will be running on it.
  5. Not The Same As The Old Boss: both the tools and the policies that used to work in the world of “real” servers won’t necessarily work in the new world of virtual servers. You’re going to have to find / make new ones.
  6. Virtual Tools: in order to police your virtual machines, you are going to want your security tools to run on virtual machines also – makes sense, doesn’t it?
  7. Cutting Costs: how many CPU cycles your virtual security tools take up will be a huge deal very quickly. The rule of thumb is for them to take less than 2-3% of the CPU’s cycles.
  8. Policy Update Time: not only will you need fancy new tools, but you are also going to need to update your staff on just how one goes about securing virtual boxes. Can you say special training?
  9. Where To Focus?: the experts suggest that you spend your time securing both the virtual machine and its applications and don’t worry so much about the underlying virtual machines. The thinking is that virtual machines are by design isolated from everything else so they are more secure.
  10. Get Some Relief: look for virtual machine management tools that will allow your staff to automate the processes of configuring and deploying virtual machines as much as possible in order to minimize security slipups.

Final Thoughts

Like it or not, when you become CIO you’re going to be living in a virtual world. All of the clever security tools and policies that we’ve created in an attempt to secure the world of physical servers that we now live in are not going to work in the future.

Your challenge will be to find ways to secure the virtual data center while at the same time keeping your IT staff’s workload at a manageable level. The good news is that this can be done, the bad news is that you’re going to be in uncharted territory. Good luck future CIO…!

Poisonous Snakes, Sharp Knives, And Angry Natives: How Much Risk Can You Handle?

CIOs Know That Security Threats Can Strike At Any Time

CIOs Know That Security Threats Can Strike At Any Time

Ok CIO wannabe, we’re right in the middle of a global financial crisis and your IT budget has gotten slashed so much it looks like Freddie Krueger has come back and had his way with it. What are you going to do about your spending on security programs: cut ‘em, hold the line, or spend more. Whoops – that was a trick question: all of the answers will get you in trouble.

What The Other Guys Are Doing

Before making any big spending decision, any self-respecting CIO will do what all leaders do – try to find out what the other guys are doing in the hopes that you can just copy them. Well, in this case you’ll be getting mixed signals.

A survey done by Information Week magazine revealed that 19% of CIOs are cutting their security spending. On top of that, only 27% of the surveyed CIOs are planning on increasing their security budgets – that leaves roughly 50% doing the same old thing.

Its starting to look as though the final remaining sacred cow of IT budgets, spending on securing the enterprise’s IT assets, has finally fallen under the budget trimming axe. This is an excellent opportunity to learn how to be a better CIO: cut too little and the company goes under, cut too much and the company may get sued when your defenses are breached.

What’s Worse: Poisonous Snakes or Sharp Knives?

Here’s another part of your CIO quiz: when your security budget comes under fire and you know that you’re not going to be able to save the whole platoon, who do you pick to live and who do you let die? Tough call eh? That Information Week CIO survey revealed that most CIOs have decided that any security program that deals with compliance in some way, shape, or form needs to be saved.

In the end, CIOs are finally starting to realize that an effective corporate IT security policy consists of just two things:

  • Managing Risk
  • Protecting Data

Don’t Forget About The Angry Natives -
How CIOs Prioritize

If the job was easy, then anyone could be a CIO. The CIOs who get it, those who understand what effective IT security is really trying to do, know that the first thing that they have to do is to determine the company’s overall appetite for risk. If the company has an appetite for a lot of risk, then the CIO can trim the IT security budget to the bone. Otherwise, cut with care!

Successful CIOs realize that the right way to go about setting up an IT security program is to start by realizing that you can’t protect everything to the same level and so you need to identify what IT assets are the most valuable to the company. Once you know this, you need to take the next step and estimate the likelihood that those assets might be lost.

Only after you have both of these pieces of information can a CIO have the IT team start to create security programs and put systems of controls in place to protect what needs to be protected. Although compliance programs are on everyone’s minds in these tough economic times, CIOs need to keep in mind that such programs are not always in line with security best practices.

Final Thoughts

If you want to have any hope of ever being a successful CIO, you’ve got to learn to be able to make the tough calls when it comes to funding corporate IT security programs. Although putting measures in place in order to make sure that the company remains complaint with regulations is good, it’s not nearly enough.

Taking the time to properly value your corporate IT assets and identifying what kinds of risks this data faces is the critical first step that too many CIOs skip over. Take the time to do this correctly and you’ll be well positioned to deal with poisonous snakes, sharp knives, and angry natives. Now if we could just find some way to deal with those pesky rampaging elephants…

What do you think should be a CIO’s #1 security concern: remaining in compliance or dealing with the security threat that comes from outside?

The Insider Threat: What CIOs Need To Know

Monday, October 12th, 2009
CIOs Know That Insiders Represent The Biggest Threat   (c) - 2004

CIOs Know That Insiders Represent The Biggest Threat (c) - 2004

When you think about someone trying to make off with your company’s private data, what comes to mind? Some wily Russian hacker who sneaks into your company’s network through the backdoor? Perhaps you need to update your thinking. A recent report from Cisco revealed that the real threat is coming from insiders. What’s a CIO to do?

Identifying The Threat

By now all CIOs realize that their corporate networks and data are under almost constant assault. However, most of the steps that CIOs have taken to secure their networks have been designed to defend themselves against the attacker who comes from the outside.

Information that was revealed in the Cisco report included that workers are sharing corporate information with outsiders for a variety of reasons. These include sharing data simply in order to get an outsider’s opinion on something, to show off work that they’ve done to others, etc.

On top of the active taking of corporate data, Cisco’s report revealed that some 66% of those who responded admitted to engaging in activities that would allow someone else to access corporate data (things like not logging off and then leaving their computers on at work overnight!)

Data Loss Prevention

If a CIO ever wants to get to sleep again, something has to be done to solve the data loss threat that insiders pose to the firm. There is no magic bullet, but one approach to dealing with this problem is to deploy a data loss prevention (DLP) suite of tools.

In true “big brother” fashion, a DLP suite generally consists of a network scanner coupled with multiple tools that allow an IT department to collect information on what data is being used and by whom.

Before moving forward with implementing a DLP solution, CIOs need to take the time to prepare to use this new set of tools. The steps involved include:

  • Secure The Important Stuff: before you go worrying about trying to secure how data is used throughout the enterprise, first identify the most important data and ensure that it is locked down.
  • Close Your (Network) Doors: before you can worry about insiders doing you harm, you need to make sure that outsiders can’t get in. This requires analyzing both your network ports and the protocols that the company’s network is using to make sure that they are secure.
  • Create A Baseline: in order to detect when the wrong things are being done, you need some way to detect them. Creating baselines such as point-in-time content signatures for sensitive data stores is a first step in doing this.
  • Start Inspecting Traffic: the way that you can prevent information from going to internal sources that don’t have a need to know is by installing automated network traffic inspectors. Setting parameters so that notifications of data breeches are flagged will do a great deal to prevent data loss by internal threats.

Final Thoughts

The value that a CIO brings to a firm is that he / she is able to harness IT resources in order to help the company succeed. As part of this task, the CIO is also responsible to make sure that sensitive corporate data remains secure from both external and internal threats.

CIOs that learn how to deploy DLP solutions in order to protect against the data loss threat from insiders will be better at finding ways to apply IT to enable the rest of the company to grow quicker, move faster, and do more.

Since most firms have no idea about what to do with their corporate research facilities, responsibility for the labs often falls under the control of the CIO (because most firms don’t know what to do with IT either). Great. So what’s a CIO to do when he/she is responsible for a corporate R&D lab?

Halt – Who Goes There? CIOs Need Good Identity Management

CIOs Need To Solve Their ID Management Crisis<p>(c) 2007</p>

CIOs Need To Solve Their ID Management Crisis(c) 2007

As though keeping all of those servers up, applications running, and end users happy seems like enough to make being CIO a full-time job, now CIOs also have to take on the role of data cop? The answer to this question is “yes”, in all honesty, they really should already be doing it. Most company’s most valuable asset, after their employees, is their corporate data. CIOs need to find a way to make sure that they know who is accessing it and why.

Just What Is Identity Management?

Identity management is how an organization controls access to its information based on an individual’s rights and responsibilities. It turns out that most IT shops have been doing a pretty poor job of this.

All too often most of us rely on our old friends Mr. Username and Mr. Password. How many dictionary based cracking events do we need to see in the movies in order to convince us that this is a very poor way to secure our data?

The right way to start to authenticate identities better is to use a second-factor authentication system such as biometrics, tokens, etc. Additionally, using single sign-on technologies can help you bring disparate systems together and save the end users from having to carry around lists of usernames/passwords.

What’s The Best Way To Do Identity Management?

The first step to creating a workable identity management solution is to establish some policies. These policies need to lay out just who is allowed to access what information. Clearly, if you’re not allowed to use some piece of information as a part of your job, then you shouldn’t have access to it.

One of the biggest pitfalls that is found in IT departments today is the existence of multiple different “silos” of data that end up creating a confusing and mixed up environment for access control. Once again, implementing a single-signon solution can solve this problem.

Final Thoughts

Taking the time to design and implement a good identity management solution is very much like buying insurance for your IT department. You hope that you don’t really need it, but you know that you probably do and it’s the grown-up thing to do.

Taking the time to solve your identity management issues once and for all will allow a CIOs to have found a way to apply IT to enable the rest of the company to grow quicker, move faster, and do more.
