Application Whitelisting Offers CIOs Another Way To Protect Their Networks

Application Whitelisting Offers CIOs Another Way To Protect Their Networks

It’s a battle out there: hackers and organized crime groups vs. your company. Whereas you have to worry about keeping the company successful and lowering costs, all they have to worry about is finding ways to break into your network. Doesn’t seem very fair, does it? There is some good news for CIOs: application whitelisting has arrived.

What is Whitelisting?

The problem with trying to protect your company’s network is that the bad guys are always trying new and innovative things. In order to block them, you have to stay on top of what the latest attach vector is and install defenses against it throughout your network. This can be a real time waster – it’s critical to do, but it contributes nothing to the company’s bottom line.

Whitelisting applications takes a 180-degree different approach to securing your network. Instead of trying to identify and block all of the bad malware variants that are trying to get into your network, whitelisting focuses on identifying all of the applications that SHOULD be allowed to access your network.

This of course means that you need to block everything that is not whitelisted. The theory is that all that malware that shows up will find the door to your network slammed shut on them.

Whitelisting Is Not For Everyone

In some enterprise IT environments, whitelisting is the wrong way to go. In these environments, using application whitelisting can actually drive up operational costs so high that things quickly get out of hand. Ill-suited IT environments are those in which workers need to be constantly installing new and changed applications on the fly in order to complete their tasks.

Where Whitelisting Works Well

That being said, there are IT environments in which application whitelisting works very well. These environments tend to be very static with very few application changes. A great example of this is call centers.

Another example where whitelisting has worked well is in the retail sector where cash register environments are very static and only need to be updated ever six months. Some companies have discovered that they have been able to do away with anti-virus protection (and the associated cost of maintaining it) on those machines.

Final Thoughts

The fight to secure the company’s network from the forces that would do bad things to it is never-ending for CIOs. However, this is not what CIOs should be spending their time on – there is not a bottom line benefit.

Whitelisting of applications provides yet another way to secure the firm’s network by taking a novel approach to security – don’t worry about identifying the bad guys, just worry about identifying the good guys.

Whitelisting won’t work for every environment, but in certain static IT environments it can work wonders. CIOs who can identify the right IT environments in which to use application whitelisting will have found a way to apply IT to enable the rest of the company to grow quicker, move faster, and do more.

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.

Data Protection Secrets: CIOs Know That It Starts At The Endpoint

CIOs Know That Managing Endpoints Is The Key To Securing Company Data <br> <div xmlns:cc="http://creativecommons.org/ns#" about="http://www.flickr.com/photos/john/47544223/"><a rel="cc:attributionURL" href=
Just imagine this scenario: you’ve just been made CIO of your firm when all of a sudden one of your competitors suffers a massive data loss because of outside hackers. Your CEO storms into your brand-new office and demands to know what you are doing to secure your firm’s data. What would you say?

The Old Way Of Doing Things

Good CIOs realize that a firm’s IT infrastructure can’t just be thought of “those boxes”. Instead, an IT infrastructure consists of three layers of devices: core servers and perhaps mainframes, a set of network connectivity devices such as routers and hubs, and then endpoints – the PCs and laptops that you and I use every day.

IT Networks Consist Of 3 Separate Levels Of Equipment

IT Networks Consist Of 3 Separate Levels Of Equipment

Since there are more endpoints than any other type of equipment in most corporate networks, CIOs realize that this is where must of their company data loss efforts must be focused.

In the past, securing network endpoints often meant that all one had to do was to load up some anti-virus software on every laptop and you could check this off of your CIO to-do list. Sorry – that no longer works.

Welcome To The Real World

As we enter the brave new world of policy management, we are seeing a shift to policy-based enforcement being used to control company data that is being used on enterprise network endpoints.

Using policy-base management of endpoints allows multiple areas to be managed. These areas include:

  • Configuration
  • Patch
  • Access
  • Application
  • Anti-virus

The Case For Using Policy-Based Management of Endpoints

Let’s face it – we are all have too much to do and too little time in which to get it all done. Establishing corporate IT polices allows a set of rules to be laid down that tell everyone what is and is not permitted. When you extend these polices to cover how you manage the endpoints of the company’s network, then all of a sudden you’ve made your life that much easier.

Policies allow you to prioritize the company information that you want to protect. Once you identify this information, you’ll then be able to realize just how much of it is being stored on the endpoints!

This new understanding then allows you to set up a systems security approach to making your PCs and laptops safe. By doing this you’ll be able to ensure that your network endpoints are now secure places to house that valuable corporate data.

Final Thoughts

There’s no way that any one person in an IT department can make sure that all of your PCs and laptops are secure all the time – even if you are the CIO. Yesterday’s piecemeal approach of placing an anti-virus application on each PC and then considering the job done was a poor solution.

Using a system’s approach and establishing company policies for how management of endpoints should be done sets up a much simpler way of ensuring that all endpoints are secure. CIOs that do this will have found a way to apply IT to enable the rest of the company to grow quicker, move faster, and do more.

Security Policies Are What CIOs Know Make Good Security Solutions

CIO's Realize That A Good Security Program Requires A Good Set Of Policies

CIO's Realize That A Good Security Program Requires A Good Set Of Policies

What does it take to do a really good job of securing your company’s systems and data? Is it just a matter of picking and implementing the right software or hardware solution? Is there a consulting firm that you can pay millions to who will come in and take care of this problem once and for all? Bad news – the answer is no.

How Policies Make A Security Program Work

Securing a firm’s systems and data is a daunting task. The first step to successful doing this is to develop a risk management program that captures and describes all of the various internal and external risks that your firm is currently facing. Next comes the prioritization which allows you to determine which of these risks is most likely to affect your firm – all risks are not created equal.

Once you have prioritized the risks that your firm is facing, the CIO needs to step in and make sure that a program of actionable policies is created in order to secure your systems. All too often, this is the step that gets skipped and no matter how much technology you throw at the security problem, if you don’t have a good set of polices you’ll never be able to secure your systems.

Polices Secure Your Systems From Day-To-Day

What too many CIOs tend to forget is that the key to any company’s security program is the human element and you manage this by having a clearly understood set of policies in place. Creating the policies is a first step, making sure that everyone knows about the policies and is living them are the next steps.

Kevin Mitnick is a reformed computer hacker who tours the country talking to businesses about the importance of securing their systems. I had an opportunity to hear him talk recently and it was amazing to hear how he acquired the information that he needed to break into company computer systems.

Kevin used a technique called “social engineering“ in which he would basically call up someone and ask them for sensitive system information. No matter if the firms had a corporate security policy in effect, Kevin was basically able to get the people that he called to violate it. No, they weren’t angry with their company, they were just trying too hard to be helpful. That’s what can happen if you don’t have security policies that are well known by everyone.

Final Thoughts

Doing a risk analysis and prioritizing the results is easy for IT professionals to do. However, creating policies that need to be followed by humans and then actually convincing their coworkers to follow the policies can be a real challenge.

A CIO can ensure that security policies will be successful by publicly stating his / her support for the policies and then by following them. Everyone will know if the CIO takes the polices seriously and by showing that you do, you will have found a way to apply IT to enable the rest of the company to grow quicker, move faster, and do more.

Questions For You

Does your firm currently have security policies in-place? Have these policies been communicated to everyone? Do they understand them? How can you tell if they are following them? Are you following them? Does anyone know that you are following them? Leave me a comment and let me know what you are thinking.
