Ask The Security Experts: Mobile Policy

This time around, the experts offer insights on this question:

Q: “Dear Experts, what are the key things I need to keep in mind when I write my company’s mobile security policy?” — MK

John Davis starts us off with:

I would say the most important thing is to actually write your own policy; don’t just copy a generic mobile security policy from the Internet and adopt it as your own. For a mobile security policy to be effective, it needs to be tailored to meet your organizations particular information security requirements and also needs to reflect the reality of mobile device use at your organization. It won’t do you much good to forbid using mobile devices for business purposes if you have no mechanisms in place to prevent or detect such uses. Effective information security policy, like effective statute law, is both practical and enforceable.

Adam Hostetler added:

Keep in mind what kind of current security policies you have, and try to apply that to the mobile sphere. Users need to understand that they are connecting an additional computer to the network, and not just a “phone”. Keep in mind also what kind of deployment you are using. Is it bring your own device, or is it company provided? There will be different policies and procedures for each method and possible user backlash depending on how you are doing this.

As always, thanks to the experts for weighing in, and to the readers for the questions. Keep them coming!

Recovering Data from Dead Hard Drives

We caught this post on Lifehacker a few days ago and thought they did a pretty good job of handling a pretty frequent question. How many times have you been asked about data recovery? For us, we always ask “You have that backed up, right?”, in return. 

Sadly, few people seem to backup their data, even though that is one of the basic foundations of protecting information. 

If you are or know someone who gets into this predicament, we hope this approach helps.

In the meantime, where did you put your backup disk? You have one, right??? 🙂

Ask The Experts: Insights on Facebook Friends

This time around, the experts tackle this question:

Q: “Hey Security Experts, should I be friends with everyone that asks on Facebook? What’s the risk of friending people I don’t really know? Can we be friends on Facebook?” –Scott918

Adam Hostetler weighed in with:

I wouldn’t recommend accepting friends request for anyone on Facebook, unless you actually know them. This especially goes for somebody that claims they work at the same company as you, as it really could be somebody building a network of targets to social engineer.

Take advantage of Facebook privacy settings also. Don’t make your information public, and only make it viewable by friends. I would even recommend against putting too much personal information on there, even if it is only among friends. There have been security issues in the past that allow people to get around privacy controls, and Facebook really doesn’t need a lot of information from you anyway.

John Davis added:

The short answer is NO! I’m a big believer in the tenet the you DON’T want the whole world to know everything about you. Posting lots of personal facts, even to your known friends on Facebook, is akin to the ripples you get from tossing a pebble into still water – tidbits of info about you radiate out from your friends like waves. You never know who may access it and you can never get it back! There are lots of different people out there that you really don’t want as your friend – I’m talking about everything from annoying marketers to thieves to child molesters. People like that are trying to find out information about you all the time. Why make it easy for them?

Finally, Phil Grimes chimed in:

Facebook is a ripe playground for attackers. This is something I speak about regularly and the short answer is NO, absolutely not. If you don’t know someone, what is the benefit of “friending” them? There is no benefit. On the contrary, this opens a can of worms few of us are prepared to handle. By having friends who aren’t really friends one risks being attacked directly, in the case of the unknown friend sending malicious links or the like. There is also the risk of indirect attack. If an attacker is stalking Facebook pages, there is a lot of information that can be viewed, even if you think your privacy settings are properly set. Stranger danger applies even more on the Internet.

So, while they may not be your friends on Facebook, you can follow the Experts on Twitter (@microsolved) or keep an eye on the blog at http://www.stateofsecurity.com. Until next time, stay safe out there! 

MicroSolved Lab Services: A Secret from Behind the Locked Doors

One of the oddest, most fun and most secretive parts of MSI is our testing lab services. You don’t hear a lot about what happens back there, behind the locked doors, but that is because of our responsible disclosure commitments. We don’t often talk publicly about the testing we do in the lab, but it varies from testing unreleased operating systems, applications, hardware devices, voting mechanisms, ICS/SCADA equipment, etc. We also do a small amount of custom controls and application development for specific niche solutions. 

Mostly though, the lab breaks things. We break things using a variety of electronic tools, custom hardware, bus/interface tampering, software hacking, and even some more fun (think fire, water & electric shock) kinds of scenarios. Basically, whatever the threat model your devices or systems face, most of them can be modeled, examined, tested, simulated or otherwise tampered into place in the MSI labs.

Our labs have several segments, with a wide array of emulated environments. Some of the lab segments are virtualized environments, some are filled with discreet equipment, including many historical devices for cross testing and regression assessments, etc. Our electronics equipment also brings a set of capabilities for tampering with devices beyond the usual network focus. We often tamper with and find security issues, well below the network stack of a device. We can test a wide range of inputs, outputs and attack surfaces using state of the art techniques and creatively devious approaches.

Our labs also include the ability to leverage HoneyPoint technology to project lab tested equipment and software into parts of the Internet in very controlled simulations. Our models and HoneyPoint tools can be used to put forth fake attack surfaces into the crimestream on a global basis and identify novel attacks, model attack sources and truly provide deep threat metrics for entire systems, specific attack surfaces or components of systems. This data and the capabilities and techniques they are based upon are entirely proprietary and unique to MicroSolved.

If you would like to discuss how our lab services could assist your organization or if you have some stuff you want tested, get in touch. We would love to talk with you about some of the things we are doing, can do and some of the more creatively devious ideas we have for the future. 🙂

Drop us a line or give us a call today.  We look forward to engaging with you and as always, thanks for reading! 

Ask The Experts: Advice to New InfoSec Folks

This time our question came from a follow up on our last advice article to new infosec folks (here). Readers might also want to roll back the clock and check out our historic post “So You Wanna Be in InfoSec” from a few years ago. 

Question: “I really want to know what advice the Experts would give to someone looking to get into the information security business. What should they do to get up to speed and what should they do to participate in the infosec community?”

Adam Hostetler replied:

To get up to speed, I think you should start with a good foundation of knowledge. Already working in IT will help, you should then already have a good idea of networking knowledge, protocols, and architecture, as well as good OS administrative skills. Having this knowledge already helped me a lot at the beginning. Then I would move into the infosec world, read and listen to everything you can related to infosec.  There’s much much more security related knowledge online than ever before, so use it to your advantage. You also now have the opportunity to take info sec programs in colleges, which weren’t really available 10 years ago. Social Networking is very important too, and how you would likely land a job in infosec. Go to events, conferences or local infosec meetings. Some of the local infosec meetings here in Columbus are ISSA, OWASP, and Security MBA. Find some in your area, and attend something like Security B-Sides, if you can. Get to know people at these places, let them know you’re interested, and you might just end up with your dream job.

John Davis chimed in:

If you want to get into the risk management side of the information security business, first and above all I recommend that you read, read, read! Read the NIST 800 series,  ISO 27001 & 27002, the PCI DSS, CobiT, the CAG, information security books, magazine articles, and anything else you can find about information security. Risk assessment, ERM, business continuity planning, incident response and other risk management functions are the milieu of the generalist; the broader your knowledge base, the more effective you are going to be. To participate in the infosec community, there are several things you can do. Probably the best and quickest way to get started is to attend (and participate in) meetings of information security professional organizations such as ISSA, ISACA and OWASP. Talk to the attendees, ask questions, see if they know of any entry level positions or internships you might be able to get into. There are also infosec webinars, summits and conferences that you can participate in. Once you get your foot in the door someplace, stick with it! It takes time to get ahead in this business. For example, you need four years of professional infosec experience or three years experience and a pertinent college degree before you can even test for your CISSP certification.

Three Ways to Engage with the InfoSec Community

J0289893

Folks who are just coming into infosec often ask me for a few ways to engage with the infosec community and begin to build relationships. Here a few quick words of advice that I give them for making that happen.

1) Join Twitter and engage with people who are also interested in infosec. Talk directly to researchers, security visionaries and leadership. Engage with them personally and professionally to build relationships. Add value to the discussions by researching topics or presenting material that you are familiar with.

2) Join an open source software project. Even if you aren’t a coder, join the project and help with testing, documentation or reviews of some kind. Open source projects (they don’t have to be security projects) can benefit from the help, an extra set of eyes and the energy of new folks contributing to their work. You’ll learn new stuff and build great relationships in the development and likely infosec communities along the way. 

3) The way that most folks go about it works as well. Go to events. Network. Meet infosec people and engage them in discussions about technical and non-technical subjects. Groups like ISSA, ISACA, ISC2, OWASP and other regional security events are good places to meet people, learn stuff and develop relationships with folks working on hard problems. Cons can be good for this too, but often have less chances for building rapport due to the inherent sensory overload of most con environments. Cons are a good place to grow relationships, but may not be the best events for starting them.

That’s my advice. All 3 items are hard work. They offer a chance for you to learn and engage. BUT, you have to work to earn respect and rapport in this community. You have to contribute. You must add value. 

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

3 Ways to Minimize Reputational Risk With Social Media

You have employees who are addicted to social media, updating their status, sharing everything from discovering a helpful business link to where they went for lunch. However, they also may be broadcasting information not intended for public consumption.

One of the most difficult tasks for an organization is conveying the importance of discretion for employees who use social media. Not only are organizations at risk from having their networks attacked, but they must protect their reputation and proprietary ideas. What makes these two areas difficult to protect is their mobile nature. Ideas are invisible and have a habit of popping into conversations – and not always with the people who should be hearing them. They can get lost or stolen without anyone knowing they’re even gone. Suddenly, you find your competitor releasing a great product to your market that you thought was yours alone.

If you want to decrease reputational risk, you have a few options. Initiate some guidelines for employees. Send friendly reminders from newsworthy “social-media-gone-bad” stories. The more employees know where an organization stands in regard to safe social media use, the more they can be smart about using it. Here are three basic rules to help them interact safely:

1. Don’t announce interviews, raises, new jobs, or new projects.

Talking about any of these sensitive topics on social networking sites can be damaging. If an employee suddenly announces to the world that they’re working on a new project with XYZ Company, there’s a good chance the news will be seen by a competitor. You may see them in the waiting room of your client on your next visit. One caveat: If you’re hiring, it’s a good thing. Your organization will be seen as successful and growing. However, those types of updates are usually best left to the HR department.

2. Don’t badmouth current or previous employers.

It’s good to remember what mom used to say, “If you don’t have anything positive to say, then say nothing at all.” The Internet never forgets. When an employee rants about either their past employer, or worse – their current one, it can poison a customer’s view of the organization. Nothing can kill the possibility of a new sale than hearing an employee broadcast sour grapes. If this is a common occurrence, it can give the image of a badly managed company. This isn’t the message to send to either customers or future employees.

3. Stay professional. Represent the organization’s values well.

Employees are often tempted to mix their personal and work information together when using social media. Although many times, such information can be benign, you don’t want to hear about an employee’s wild night at the local strip club. There are mixed opinions among experts whether an employee should establish a personal account, separate from their work life.

Emphasize your organization’s values and mission. Ask employees to TBP (Think Before Posting). Social media can be a good experience as long as its done responsibly. With some timely reminders, reputational risk will be drastically reduced.

Malware Alert: Will You Lose Your Internet Access On Monday?

We’re always keeping our eyes and ears open when it comes to malware. If you’ve not heard of this report before now, it would be good to check your computer to see if it has been infected with a nasty piece of malware whose creators were finally caught and shut down by the FBI late in 2011.

From AllThingsD:

Next week, the Internet connections of about a quarter-million people will stop working because years ago their computers became infected with malware.

The malware is called DNSChanger, and it was the centerpiece of an Internet crime spree that came to an end last November when the FBI arrested and charged seven Eastern European men with 27 counts of wire fraud and other computer crimes. At one point, the DNSChanger malware had hijacked the Internet traffic of about a half-million PCs around the world by redirecting the victims’ Web browsers to Web sites owned by the criminals. They then cashed in on ads on those sites and racked up $14 million from the scheme. When the crackdown came, it was hailed as one of the biggest computer crime busts in history.

Complete Article

The listed site for checking if you have the malware is (not surprising) getting slammed. Try to refresh the address a few times and it will show you if your system is infected or not, plus will give you a link for how to fix your site.

Here’s to seeing “green” for everyone!

Got Disaster Recovery?

As the recent heavy storms in the Midwest has brought to my attention in a personal way — even the best laid plans can have weaknesses. In my case, it was an inconvenience, but a good lesson.

I got a reminder about cascading failures in complex systems via the AT&T data network collapse (thanks to a crushed datacenter), as well as a frontline wake-up call about the importance of calculating generator gasoline supplies properly. 

So, while you read this, I am probably out adding 30 gallons to my reserve. Plus, working on a “lessons learned” document with my family to more easily remember the things we continually have to re-invent every time there is a power outage of any duration. 

I share with you these personal lessons for a couple of reasons. First, I hope you’ll take a few moments and update/review your own personal home plans for emergencies. I hope you’ll never need them, but knowing how to handle the basics is a good thing. Then move on to how you’ll manage trivialities of personal comfort like bandwidth, coffee & beer. 🙂

Lastly, I hope you take time and review your company’s DR/BC plans as well. Now might be a good time to do exactly what I hope AT&T, Amazon, Netflix, Instagram, etc. are doing and get those plans back in line with attention to the idea that failures can and often do, cascade. This wasn’t an earthquake, tsunami or hurricane (though we did have 80+ mph winds) – it was a thunderstorm. Albeit, a big thunderstorm, but a thunderstorm nonetheless. We can do better. We should expect better. I hope we all will get better at such planning. 

As always. thanks for reading and until next time, stay safe out there. 

PS – The outpouring of personal kindness and support from friends, acquaintances and family members has been amazing. Thank you so much to all of the wonderful folks who offered to help. You are all spectacular! Thank you!

Hooray! An Open-Source Password Analyzer Tool!

 

 

 

 

 

 

 

I’m one of the resident “Password Hawks” in our office. Our techs consistently tell people to create stronger passwords because it is still one of the most common ways a hacker is able to infiltrate a network.

However, we live in an age where it’s not just hackers who are trying to steal an organization’s data. There are also a variety of malcontents who simply want to hack into someone’s account in order to embarrass them, confirm something negative about them, or be a nuisance by sending spam.

This is why it is important to create a strong password; one that will not be easily cracked.

Enter password analyzer tools. Sophos’ “Naked Security” blog posted a great article today about the often misleading security policies of popular online social sites. Developer Cameron Morris discovered that if he followed one social site’s policy, he actually created a more easily “crackable” password than the one they deemed weak.

About three years ago, developer Cameron Morris had a personal epiphany about passwords, he recently told ZDNet’s John Fontana: The time it takes to crack a password is the only true measure of its worth.

Read the rest of the article here.

There is a free analyzer you can use and I strongly suggest you test the strength of your passwords with it.

Passfault Analyzer

Also, Morris created a tool for administrators that would allow them to configure a password policy based on the time to crack, the possible technology that an attacker might be using (from an everyday computer on up to a $180,000 password attacker), and the password protection technology in use (from Microsoft Windows System security on up to 100,000 rounds of the cryptographic hash function SHA-1/).

OWASP Password Creation Slide-Tool

This is one of the best articles I’ve read on password security, plus it has tools for both the end-user and the administrator. Test them out yourself to see if you have a password that can resist a hacker! 

As for me, I think I need to do a little more strengthening…

Have a great Memorial Day weekend (for our U.S. readers) and stay safe out there!
