The Big Three Part 2: Incident Detection

Did you know that less than one out of five security incidents are detected by the organization being affected? Most organizations only find out they’ve experienced an information security incident when law enforcement comes knocking on their door, if they find out about it at all, that is. And what is more, security compromises often go undetected for months and months before they are finally discovered. This gives attackers plenty of time to get the most profit possible out of your stolen information, not to mention increasing their opportunities for further compromising your systems and the third party systems they are connected to.

Of the Big Three strategies for fighting modern cyber-crime, (incident detection, incident response and user education and awareness), incident detection is by far the hardest one to do well. This is because information security incident detection is not a simple process. No one software package or technique, no matter how expensive and sophisticated, is going to detect all security events (or even most of them to be completely honest). To be just adequate to the task, incident detection requires a lot of input from a lot of systems, it requires knowledge of what’s supposed to be on your network and how it works, it requires different types of security incident detection software packages working together harmoniously and, most importantly, it requires human attention and analysis.

First of all, you need complete sources of information. Even though it can seem to be overwhelming, it behooves us to turn on logging for everything on the network that is capable of it. Many organizations don’t log at the workstation level for example. And you can see their point; most of the action happens at the server and database level. But the unfortunate reality is that serious security compromises very often begin with simple hacks of user machines and applications.

Next, you need to be aware of all the software, firmware and hardware that are on your network at any given time. It is very difficult to monitor and detect security incidents against network resources that you aren’t even aware exist. In fact, I’ll go a step further and state that you can improve your chances of detection significantly by removing as much network clutter as possible. Only allow the devices, applications and services that are absolutely necessary for business purposes to exist on your network. The less “stuff” you have, the fewer the attack surfaces cyber-criminals have to work with and the easier it is to detect security anomalies.

The third thing that helps make information security incident detection more manageable is tuning and synchronizing the security software applications and hardware in your environment. We often see organizations that have a number of security tools in place on their networks, but we seldom see one in which all of the output and capabilities of these tools have been explored and made to work together. It is an unfortunate fact that organizations generally buy tools or subscribe to services to address particular problems that have been brought to their attention by auditors or regulators. But then the situation changes and those tools languish on the network without anyone paying much attention to them or exploring their full capabilities. Which brings to the most important factor in security incident detection: human attention and analysis.

No tool or set of tools can equal the organizational skills and anomaly detection capabilities of the human brain. That is why it is so important to have humans involved with and truly interested in information security matters. It takes human involvement to ensure that the security tools that are available are adequate to the task and are configured correctly. It takes human involvement to monitor and interpret the various outputs of those tools. And it takes human involvement to coordinate information security efforts among the other personnel employed by the organization. So if it comes down to spending money on the latest security package or on a trained infosec professional, I suggest hiring the human every time!

3 Tips for BYOD

I wanted to take a few moments to talk about 3 quick wins you can do to help better deal with the threats of BYOD. While much has been said about products and services that are emerging around this space, I wanted to tack back to 3 quick basics that can really help, especially in small and mid-size organizations.

1. Get them off the production networks – an easy and often cheap quick win is to stand up a wireless network or networks that are completely (logically and physically) separated from your production networks. Just giving folks an easy and secure way to use their devices at the office may be enough to get keep them off of your production networks. Back this up with a policy and re-issue reminders periodically about the “guest network”. Use best practices for security around the wifi and egress, and you get a quick and dirty win. In our experience, this has reduced the BYOD traffic on production segments by around 90% within 30 days. The networks have been built using consumer grade equipment in a few hours and with less than $500.00 in hardware.

2. Teach people about mobile device security – I know, awareness is hard and often doesn’t produce. But, it is worth it in this case. Explain to them the risks, threats and issues with business data on non-company owned devices. Teach them what you expect of them, and have a policy that backs it up. Create a poster-child punishment if needed, and you will see the risks drop for some time. Keep at it and it just might make a difference. Switch your media periodically – don’t be afraid to leverage video, audio, posters, articles and emails. Keep it in their face and you will be amazed at what happens in short term bursts.

3. Use what you already have to your advantage – There are hundreds of vendor white papers and configuration guides out there and it is quite likely that some of the technologies that you already have in place (network gear, AD Group Policy Objects, your DHCP & DNS architectures, etc.) can be configured to increase their value to you when considering BYOD policies and processes. Quick Google searches turned up 100’s of Cisco, Microsoft, Aruba Networks, Ayaya, etc.) white papers and slide decks. Talk to your vendors about leveraging the stuff you already have in the server room to better help manage and secure BYOD implementations. You might save money, and more importantly, you might just save your sanity. 🙂

BYOD is a challenge for many organizations, but it is not the paradigm shift that the media and the hype cycle make it out to be. Go back to the basics, get them right, and make rational choices around prevention, detection and response. Focus on the quick wins if you lack a long term strategy or large budget. With the right approach through rapid victories, you can do your team proud!

Sources for Tor Access Tools

As a follow up to my last couple of weeks posting around Tor and the research I am doing within the Tor network, I presented at the Central Ohio ISSA Security Summit around the topic of Tor Hidden Services. The audience asked some great questions, and today I wanted to post some links for folks to explore the Tor network on their own in as safe a manner as possible.

The following is a set of links for gaining access to the Tor network and a couple of links to get people started exploring Tor Hidden Services.  (Note: Be careful out there, remember, this is the ghetto of the Internet and your paranoia may vary…)

 Once you get into the Tor network, here are a couple of hidden service URLs to get you started:

http://kpvz7ki2v5agwt35.onion – Original hidden wiki site

http://3g2upl4pq6kufc4m.onion/ – Duck Duck Go search engine

http://kbhpodhnfxl3clb4.onion – “Tor Search” search engine

As always, thanks for reading and stay safe out there!

The video is from Bloomberg Business Week and is located here.

Check it out and circulate it amongst your management team when asked about what this “Tor” thing is and why they should care.

As always, thanks for reading and we hope these free awareness tools help your organization out.

Let’s Get Proactive with End User Security

Where do most of the threats to the security of our IT systems lurk? The Internet, of course! Powerful malicious software apps are all over the Net, like website land mines, just waiting to explode into your computer if you touch them. And how about accessing social networks from your company work station? Do you really think that content on these sites is secured and only available to those you chose to see it? If so, then Im sorry to disillusion you.

So why do most concerns still let their employees casually access and surf the Web from their business systems? Especially in the present when most everyone has a smart phone or pad with them at all times? Businesses should embrace this situation and use it to their advantage. Why not set up an employee wireless network with all the appropriate security measures in place just for Internet access? (This network should be totally separate from business networks and not accessible by business computers). Its not expensive or difficult to administer and maintain a network like this, and employees could access websites to their hearts content (on their off time of course). And for those employees that are without a smart phone (an ever dwindling few), you could stand up a few kiosk computers that they could access using their employee wireless network password.

As for employees that need Internet access to perform their work duties, you should lock their access down tight. The best thing to do is to add needed websites to a white list and only allow those employees with a business need to access only those websites that are necessary and no others. Black listing and web filtering are partially effective, but they dont really work well enough. I cant tell you how often we have seen such filters in place at businesses that we assess that prevent access to gaming and porn sites, but still allow access to traps like known malicious websites in foreign countries! Go figure.

And dont forget to properly segment your business networks. Users should only be allowed access to those network resources that they need for business purposes. Users in workstation space should never be allowed to seeinto server space. Preventing this will go a long way in curtailing attacks from the other big danger the malicious insider.

Deals for Replacing XP for Home & Small Business

Now that Windows XP is end-of-lifed, it is wise to replace it at home and in businesses of all sizes. Malware and vulnerabilities for XP are likely to skyrocket over the coming months, making it a very unsafe platform, indeed.

To help with replacement, we at MSI went shopping for some deals on Windows 7 and Windows 8 for you. Here are the deals we found on newer Windows software. Please note, we have no affiliation with any of these vendors and can’t recommend them in particular. We simply found the best prices we could identify for Windows OS. Your milage and paranoia may vary.

Here are the deals we could find:

For one PC license of Windows 7 Pro for as low as $69.99.

If you need more than one,  the lowest is $219.99.

For Windows 8 Pro – $79.94 for single computer use.

The price is $199.99 for multiple computer to use Windows 8 Pro.

We hope that helps some of you who still need to upgrade. Until next time, thanks for reading & stay safe out there! 

OpenSSL Problem is HUGE – PAY ATTENTION

If you use OpenSSL anywhere, or use a product that does (and that’s a LOT of products), you need to understand that a critical vulnerability has been released, along with a variety of tools and exploit code to take advantage of the issue.

The attack allows an attacker to remotely tamper with OpenSSL implementations to dump PLAIN TEXT secrets, passwords, encryption keys, certificates, etc. They can then use this information against you.

You can read more about the vulnerability itself here. 

THIS IS A SERIOUS ISSUE. Literally, and without exaggeration, the early estimates on this issue are that 90%+ of major web sites and software packages using OpenSSL as a base are vulnerable. This includes HTTPS implementations, many mail server implementations, chat systems, ICS/SCADA devices, SSL VPNs, many embedded devices, etc. The lifetime of this issue is likely to be long and miserable.

Those things that can be patched and upgraded should be done as quickly as possible. Vendors are working on patching their implementations and products, so a lot of updates and patches will be forthcoming in the next few days to weeks. For many sites, patching has already begun, and you might notice a lot of new certificates for sites around the web.

Our best advice at this point is to patch your stuff as quickly as possible. It is also advisable to change any passwords, certificates or credentials that may have been impacted – including on personal sites like banking, forums, Twitter, Facebook, etc. If you aren’t using unique passwords for every site along with a password vault, now is the time to step up. Additionally, this is a good time to implement or enable multi-factor authentication for all accounts where it is possible. These steps will help minimize future attacks and compromises, including fall out from this vulnerability.

Please, socialize this message. All Internet users need to be aware of the problem and the mitigations needed, even for personal safety online.

As always, thanks for reading, and if you have any questions about the issues, please let us know. We are here to help!
