Editor's Corner

This week's newsletter is all about implementing cloud computing in the shadows of your organization. That's when an employee or department surreptitiously begins making use of a public or hosted cloud service provider's offering without first getting the necessary authorization from your organization's management for doing so. Of course it's not only your employees who may sometimes operate in the shadows, you also need to watch out for your vendors as this Dilbert comic strip hints:


From the Mailbag

Last week in Issue #994 Account Lockout Flame Wars we looked at the strongly diverging opinions within the IT pro community concerning whether to use account lockout in Active Directory environments. Here's a sample of the feedback we received on that issue.

Rob, a Technical Lead for the Security Team of a large enterprise, sent us this feedback:

There is another consideration regarding account lockouts. Account lockouts can be used to create a DoS situation and shutdown users, or manufacturing systems, and plants. The risk has to be examined and properly considered in light of defense in depth measures. Brute force attacks can be identified and blocked automatically, without requiring account lockout policies. Every environment is different, and many times there are different environments within the same organization such as the LAN versus DMZ. We do not use account lockouts on our LAN, but they are mandatory in our DMZ.

I asked Rob if they implemented account lockout on their DMZ servers using local GPOs and he replied:

Our DMZ systems are not members of our internal Windows Active Directory. They are standalone servers, with their own local accounts and policies...

Yes, local GPOs are configured to lockout accounts. Our DMZ is very strict about traffic entering our network, additionally we have IPS's at all choke points including the firewalls and IDS's monitoring all traffic through devices that support NetFlow. We are in the process of implementing Symantec Critical System Protection, which has the ability to monitor and alert on brute force attacks. I am uncertain if it will drop the attackers session upon detection.

 We had suffered a near total lockout of accounts some years ago while we were beginning to implement our internal firewalls. These internal firewalls restrict inbound traffic from our global network of affiliates, HQ and others. Once the firewalls were in place we took extra care to allow only authorized inbound traffic, and was particularly interested in blocking inbound requests from outside desktop subnets to our own desktop subnets, to prevent the propagation of worms. This has worked very well for us, but took a lot of time and work to identify our corporate subnets globally.

I also asked him if he could recommend any products or solutions for automatically blocking brute force attacks and he replied:

Cisco IPs's can be configured to detect/block brute force attacks and probably most other IPS's as well [see Detecting Account Brute Forcing on this page]:

A reader named Sam took a somewhat different view concerning account lockout and shared the following story and some recommendations with us:

The following is a real event: A large Health organization hired an intern to work in the accounting area, there was no lockout policy and she downloaded the personal information of about 10,000 patients. She said, that she just kept trying different passwords, till she cracked the patients database. Her boyfriend was caught selling the information on line and now both are serving time in a federal prison.

We are for strong account lockout policies. Here is some of our reasoning:

A. Not having a lockout policy is akin to not having a login password, yes there are those that rebel against that basic security requirement. In our opinion they just don't care for the consequences of their inactions.

B. It defeats the purpose of securing a network and therefore is completely unacceptable, plainly: "what is wrong with you, can't remember your own created password?".

C. Given all the types of attacks that networks face today, not having a lockout policy is against any first line of defense against hackers ( DoS, sensitive data breach, etc.), imagine leaving your house front door unlocked forever hoping that nobody ever turns the knob!

D. In large enterprises, all types of assorted individuals work, most are decent and trustworthy but the larger the enterprise the more likely that the security breaches come from within (WikiLeaks, Target).

E. As for it been an administrative nightmare, some suggestions:

1. Remote unlock, it takes less time that fixing a corrupted database due to.....paperwork to explain to superiors how the "event" happened...... interacting with law enforcement, etc.

2. Strong HR policies including , verbal warnings, write-ups, probation and termination for abusive users.

3. Fix those apps that are causing problems (what else are they not doing correctly, maybe time for an upgrade)

4. Make time for managing your lockout policies (yes, plural, like a policy for smart cards (they do go bad also and then??????? Plan B is??????) vs keyboard), fingerprint, retina scan, etc.

5. Lockout policies are not a panacea so don't forget to include other policies like time limits policies, no flash drive download, no emailing of certain types of info, diagrams, R&D, etc.

6. Continuous review of security policies, for no static policy is infallible.

Our philosophy is basically to be prepared for the worst and to make preventive policies a way of operations (paranoia approach), because they are out to get us!!!!!!! Lockout policies are a significant part of the overall security policy of the network, alongside with physical security and others. Our lockout is set to 3 attempts. After a period of adjustment, it has worked really well; at the beginning many calls for unlocking and now very few, mostly from new employees. The only way to shape the enterprise security culture is with strong measures like a lockout and if it continues a trip to HR for disciplinary counselling.

 And now on to the main topic of this week's newsletter...

Beneath the Shadow of the Cloud

A friend of mine Yuri Diogenes pointed out an article called "Shadow cloud services pose a growing risk to enterprises" on ComputerWorld that you can read here:

The article is about the risks involved when individuals or departments within a company decide to sign up for cloud services without first gaining the blessing of management.

But before we get to this, if you're on Twitter you may want to follow Yuri:

Anyways, of course "shadow IT" has been around as long as computers have been available and readily affordable. Copying company data onto removable storage so you can take it home to do your work is an example of end-users doing an end run around the controls IT has put in place to safeguard sensitive business information. The endless proliferation of SharePoint sites could also be considered a form of shadow IT since most of the time such sites are self-provisioned without any oversight from the IT department. Other examples of shadow IT can range from setting up unauthorized WiFi access points to deploying whole Active Directory domains of PCs with their own DHCP servers.

And then there's the cloud.

One can argue that the main driver behind business units surreptitiously signing up for cloud services with a public or hosted cloud provider is the backwards-looking overly-restrictive resistance to change evidenced by IT departments in large organizations. Because of such inertia, and because employees are driven to perform in order to be rewarded (or at least not be penalized) it's becoming commonplace for those whose workflow can benefit from using cloud-based services to simply go ahead and secretly implement them in the office.

The problem with this as the ComputerWorld article points out is that parallel IT infrastructures like this that are operating in the shadows are not parallel at all. They touch the company's own infrastructure at various points, and where they touch can represent vectors for new forms of attack on the company's business assets. And the problem is magnified by how cloud services are becoming cheaper, more powerful, and easier to sign up for and use.

How can cloud-based shadow IT like this be controlled? Should it be controlled? What controls, technical or policy-based, has your own organization put in place to limit the possible damage that may occur from cloud-based shadow IT being present in your environment?

Tip of the Week - Call That Girl's Guide to Remote Support

Earlier this year we examined various remote login solutions in two issues of this newsletter, namely Issue #964 Remote Login to Desktop PCs and Issue #965 More Remote Login Solutions. Subsequent issues discussed additional remote login solutions in their Mailbag sections. Of course, one important use of remote login is to provide remote support for users, both for businesses and consumers.

Along those lines I recently came across a resource you might want to check out. It's called "Call That Girl's Guide to Remote Support", and it's an eBook series about how to set up and run a business that provides remote support to other businesses. It was also written for working technicians who need to learn remote support skills as our industry is going more into the cloud, the skills you will learn are invaluable. An aspiring networking student who is preparing for their careers in the IT industry can also take many of Lisa's tips on with them to their next job. Learning valuable remote support customer service skills is critical in today's fast moving support world. Included with purchase are documents and templates, and you can read more about the eBook here:

You can also email Lisa directly with questions about the eBook at [email protected]
