After several discussions the last few days with a number of folks around mobile technologies and the security risks they pose to organizations, I thought I might be able to help folks by putting forth a quick a dirty (“back of the napkin”) framework diagram.

This should easily demonstrate a high level strategy and give you some thinking points about how your organization manages mobile devices and data interactions from them.
As always, thanks for reading and feel free to engage with me via twitter (@lbhuston), phone or email if you want to discuss the framework or any of the components. My team is always available to help and willing to engage with readers for help with creating the components or reviewing what you have so far. I hope this helps some folks!

“We’re not seeing good reporting processes yet. Many organizations… do not know who has these mobile devices or where they are located and what they’re being used for.”  – Brent Huston, CEO, MicroSolved, Inc.

Samsung Galaxy, Google Android, Apple iPad — mobile devices are a hot item and consumers are bringing them to their workplaces. Along with the popularity are malware developers who would like nothing better than to steal sensitive information from them. How can you protect your organization’s data from mobile device usage? Discussion questions include:

  • Who is managing mobile devices?
  • There needs to be some reporting – who does this and who should be involved?
  • Who are the groups that should be included when talking about mobile security? How should an organization start their strategy?
  • Regarding the data layer: what controls can we wrap around the data itself?

Smartphones and Banking Applications

Mobile banking users are predicted to reach 400 million by 2013, according to a study by Juniper Research.

The report author, Howard Wilcox, says that transactional or “push” mobile banking is being offered increasingly by banks via downloadable applications or the mobile web, complementing existing SMS messaging services for balance and simple information enquiries.

“For the user it’s about three things: convenience, convenience and convenience,” Mr. Wilcox said. “The mobile device is almost always with you, and if you organize your life with your mobile, then why not your finances too?

“For example, people can receive account alerts and reminders straight away and take action immediately if necessary – say to top up an account or pay a bill,” he said. “With apps, the whole process is made so much simpler too.”

We know consumers want to make their lives easier — and using applications on their mobile phones seems to promise that, but how can you secure those applications?
Here are some of the steps you can take to start making your mobile applications secure:

  • Security controls: One of the main issues with smartphone applications is access control. These apps are usually used in the most vulnerable locations: public settings such as airports, restaurants, and lobbies. All mobile devices must have a protective mechanism that allows it to be accessed by authorized persons only. A few ways to monitor control would be: install anti-virus software, file encryption, session encryption, device registration, and password complexity rules.
  • User authentication: Access privileges are limited to those who use the smartphone device. Personal identification numbers are generally an acceptable means of authentication because they reside on the device only and are never transmitted.
  • Data Encryption: A powerful defense tool, encryption prevents anyone but the most savvy attacker to access important information. Ensure that the process is automatic and transparent to the user and protects all stored data. Systems that require user involvement to encrypt specific files in specific places cannot provide the “provable” security regime needed by organizations. Encryption is effective only if authorized people control the decryption key, so there needs to be a connection between encryption and user authentication. Access control, user authentication and encryption are the three elements that comprise virtual physical-access control.
  • Security administration: This needs to be in place for customers who have questions or need help. Policy enforcement, deployment, updates, help desk, key recovery and system logging are all vital components of an enterprise system that provides “provable” security to comply with data privacy regulations and to repel litigation.

Many phones use RSA encryption for authentication. While most of the big antivirus vendors provide security solutions for smartphones, few have the “silver bullet” for all platforms. As device manufacturers continue to add processing power and storage capacity; and platform vendors provide more applications for generating and consuming data, security will become a greater concern as attackers look upon it as their new playground.

Yet Another Lesson on the Basics from DigiNotar

This time it was a Certificate Authority (again). Not just any CA, either, but an official CA that manages the “PKIOverheid” for the government of the Netherlands. In other words, a really important CA, even in a league where most, if not all, CA’s are important.

What happened? They got breached. They got breached in a way that allowed attackers to create at least 531 rogue certificates with their trust models. How did they get breached? It seems to stem from a combination of attackers exploiting basic issues to gain access, then leveraging more advanced custom skills to get the certificates generated and extrude them. I am basing that opinion on the Fox-IT report located here. (The report itself is well worth a read).

The critical issues identified?

  • Lack of a secure architecture for CA servers (1 Windows domain, connectivity from management network)
  • Missing patches
  • Lack of basic controls (AV, in this case) which allowed exploitation by basic attacker tools such as Cain/Abel
  • Poor password policies, logging and management of detective controls

If you follow our blog, attend our talks or listen to our podcasts, you should be seeing this as another reminder of just how critical it is to do the basics. Having powerful tools that no one watches, engaging vendors to do assessments that you ignore and spending money on controls that don’t matter won’t create an effective information security program. Getting the basic controls and processes in place might not protect you from breaches against resourced, skilled attackers completely, either, but it will go a long way toward giving you some protection from the most common threat models. In this case, it might have helped a CA know when they were under attack and take action against their threat sources to mitigate the breach before they got to the crown jewels or in this case, the crown certificates.

The attacker has been posting to Pastebin, (presumably the attacker), that they have access to other CA providers. If you are a CA or run a certificate system, now might be a good time to have someone take an independent third-party look around. It might be a good time to spend a few extra cycles on “just checking things out”.

If your organization is still stuck chasing vulnerabilities and hasn’t done a holistic review of their overall program, this would be a good impetus to do so. It should become an action item to look at your program through the lens of something like the SANS CAG or our 80/20 of Information Security lens and ensure that you have the basics covered in an effective manner. If you have questions or want to discuss the impacts or issues some of these recent breaches have against your organization, give us a call. As aways, thanks for reading and stay safe out there.

MicroSolved Releases HoneyPoint Special Edition: Morto

Posted on by
1

We are pleased to announce the immediate availability of a special edition of HoneyPoint that is designed to help organizations identify hosts infected with the Morto worm that is currently circulating.

HPMorto works like this: It opens a TCP listener HoneyPoint on port 3389/TCP (check to make sure that port is NOT in use before running HPMorto). Once in place, the tool will report the source IP of any systems who attempt to connect to it. Identified sources should be investigated as possible infected hosts.

This version will only listen for 3389 connections and will only function through February 28, 2012.

Versions of HPMorto are available for FREE download for:
Windows 
Linux 
Mac OSX

Give it a try and we hope that this tool help folks manage the problems being caused by Morto around the world.

McAfee: 65 Million Malware Samples — And That’s Just the Tip of the Iceberg

Posted on by

I was fascinated by this article that came across my newsfeed earlier this week. In it, McAfee says that they have hit 65 million malware samples in the 2nd quarter of 2011. I have heard similar stories in my frequent conversations with other AV vendors this year. It seems, that the malware cat, truly is out of the bag. I don’t know about you, but it seems like someone forgot to warn the crimeware world about opening Pandora’s box.

One of the things that I think is still interesting about the number of signatures that AV vendors are creating are that they are still hitting only a small portion of the overall mountain of malware. For example, many of the AV vendors do not cover very many of the current PHP and ASP malware that is making the rounds. If you follow me on twitter (@LBHuston), then you have likely seen some of the examples I have been posting for the last year or so about this missing coverage. In addition, in many of the public talks I have been giving, many folks have had wide discussions about whether or not AV vendors should be including such coverage. Many people continue to be amazed at just how difficult the role of the AV vendor has become. With so much malware available, and so many kits on the market, the problem just continues to get worse and worse. Additionally, many vendors are still dealing with even the most simple evasion techniques. With all of that in mind, the role and work of AV vendors is truly becoming a nightmare.

Hopefully, this report will give some folks insight into the challenges that the AV teams are facing. AV is a good baseline solution. However, it is critical that administrators and network security teams understand the limitations of this solution. Simple heuristics will not do in a malware world where code entropy, encoding and new evasion techniques are running wild. AV vendors and the rest of us must begin to embrace the idea of anomaly detection. We must find new ways to identify code, and its behavior mechanisms that are potentially damaging. In our case, we have tried to take such steps forward in our HoneyPoint line of products and our WASP product in particular. While not a panacea, it is a new way of looking at the problem and it brings new visibility and new capability to security teams.

I enjoyed this article and I really hope it creates a new level of discussion around the complexities of malware and the controls that are required by most organizations to manage malware threats. If you still believe that simple AV or no malware controls at all are any kind of a solution, quite frankly, you’re simply doing it wrong. As always, thanks for reading and stay safe out there.
