ITWorld: How to bridge and secure air gap networks

The state of the art on Air Gap networks is changing with both better protective  technologies and sneakier threats that take advantage of some very elegant and extreme hacks. One of the more interesting security best practices is about to get turned on its head, thanks to some cutting-edge research at a small Israeli think tank and elsewhere. The notion is called an “air gap network” and the idea is to isolate a PC from the big bad Internet and any other communications networks so as to have complete security with the information that resides therein.

I talk about some of the latest research coming out of Israel on how to defeat these networks in a piece for ITWorld today.

How Lastline has better breach detection capabilities

The Internet is a nasty place, and getting nastier. Current breach detection products using traditional anti-malware sandbox technologies can’t keep up with advanced persistent and hyper-evasive threats that pummel enterprise networks on an hourly basis. Malware authors encode their exploits with a number of operational vectors, so in case one entry point doesn’t work they can still find a way into your network to do their dirty work. And as more businesses hire more outsourced consultants, part-time workers, and employ mobile devices, they open up additional mechanisms for malware to enter their corporate networks.

Some traditional AV and endpoint protection vendors have responded to these threats by adding features to their security products to do a better job of anticipating badly behaving packets coming through their detectors. They make use of limited virtual machines or operating system emulators to view how a piece of malware operates. That is great, but it isn’t enough. Many malware authors can detect when these simulated environments are active and can evade detection accordingly. For example, some exploits such as W32.DelfInj can literally go to sleep for several days to avoid any detector that will just scan an infected system for the first several minutes.

1aWhat is needed is a next-generation sandbox that can correlate a series of particular breach events add IP and object based reputation analysis and do this in near real-time. This is what the Lastline Breach Detection Platform does.  What makes them unique is their range of discovery, the way they can effectively mimic actual PC or smartphone endpoints to examine malware behavior, and how they can scale up to handle very large networks with their modular and SaaS-based tools.

SearchSecurity: Multifactor authentication in the enterprise

Older than the Web itself, multifactor authentication is an IT security technology method that requires people to provide multiple forms of identification or information to confirm the legitimacy of their identity for an online transaction or in order to gain access to a corporate application. The goal of multifactor authentication use is to increase the difficulty with which an adversary can exploit the login process to freely roam around personal or corporate networks and compromise computers to steal confidential information, or worse.

This series began in October 2014 and continued over several articles with the last of the series running in January 2015:

And then I have specific reviews of some of the leading MFA tools:

A Better Way to Do Multifactor Authentication with Authentify xFA

xFA can add multifactor security to any web service with a few lines of code. We tested xFA on a small network in August 2014. It has cloud-based components to manage multifactor security, along with apps for iOS and Android.

Price: $19.95 per user per year

Fingerprint authenticators for iPhone 5 and Samsung Galaxy are expected for the near future.

Network World: Citrix Xen Mobile rates a spot on your MDM short list

xen phone security optionsWhen we reviewed six mobile device management products for Network World back in 2013, Citrix declined the opportunity to participate, but the company has changed its mind with the recent release of Xen Mobile v9.0 MDM. In our testing, we found that the software stacks up nicely against AirWatch and Good Technology, the two leaders from that review, and should be on any IT manager’s short list, particularly if you already use other Citrix connectivity products. (A view of its extensive security options can be seen on the right.)

AT&T Blog: Network Security, The Moving Line of Defense

lock-and-key-icon-thumb355812The days of defending the perimeter are over. Look at what happened to a major retailer in late 2013 as an example. Someone posing as a trusted contractor was able to enter the retailer’s network and do all sorts of damage — to the tune of 40 million compromised customers. This attack occurred because the retailer wasn’t looking at insider threats carefully enough. Indeed, the perimeter has become more and more porous, and network defenses based on this traditional barrier are no longer enough to protect an organization’s business interests and objectives

Webinar: Best Practices for Protecting Sensitive Data from Insider Threats

Join me and Tina Stewart, the VP of Marketing for Vormetric, in an interesting webinar on 7/22 at 11 am PT. Insider threats have shifted to include both traditional insiders – individuals with access to critical data as part of their work, and privileged users — and the compromise of legitimate users’ credentials by sophisticated malware and advanced persistent threats (APTs). According to the latest Insider Threat Report from Vormetric, organizations are still wrestling with this growing problem, and struggling to find an appropriate security response.

We will talk about these issues and some of the ways that IT managers can mitigate these threats. Here is the link to view the webinar recording from Virtualization Review.

SearchSecurity: Things to watch out for when buying UTM products

I offer guidance to help enterprises find the unified threat management (UTM) product that best suits their organizational needs when they’re buying security. In this article, I discuss UTM functionality, features, pricing and more.

SearchSecurity: Cyberthreat intelligence market is getting crowded

UntitledWhen it comes to dealing with zero-day threats, time is of the essence. The quicker an IT security team can respond and repel an attack, the safer the organization. Many security teams rely on pattern matches and malware databases, but these methods have become less effective as custom viruses, created almost continuously, make algorithms obsolete. Crowdsourcing threat data so that a community can act quickly and repeal potential invasions is delivering results for more enterprises. (The illustration is a typical threat workflow from CyberSquared’s ThreatConnect.)

Network World: Unisys unveils invisibility cloak for network traffic

unisys stealth advantages2If you are ultra paranoid, what could be better than hiding your network traffic in such a way that no one could possibly intercept it? This is what Unisys is offering with its new Stealth appliance, which could make man-in-the-middle attacks and keylogger exploits obsolete, or at least more difficult to mount.

Stealth uses four layers of security (see diagram): each packet is encrypted with AES256, then split into three separate pieces and dispersed across the network, destined for a particular group of users that have to be running its protocols. Stealth has been around since 2005, and you can read my review of Stealth for Network World here.
