Using Certificates for Authentication ? Where to store them ?

Question: 
Has anyone deployed a VPN solution that leverages user certificates for authentication?
We are considering the possibility of leveraging digital certificates as an authentication factor for VPN. Has anyone implemented this or looked at solutions that do this? We are not comfortable with solely relying on a certificate and the security/integrity of the PC as an authentication mechanism. If you are currently using certificates, I would be interested in hearing how you are deploying this.

Answer:
.....,
The short answer is yes.  We did deploy several off-the-shelf certificate based authentication solutions for remote access VPN systems such as Cisco, Check Point, Juniper, Citrix, Nortel.. It is again very possible to deploy similar solutions over SSL VPN solutions (This time easier since browser is the client).   I worked with Entrust as the PKI integration provider.  When using certs, most of the questions/problems are generic PKI related questions (CRLs,  OCSP, identity management etc)


9 out of 10, enterprise shops store the certs on PC or mobile devices since they want to avoid using tokens/smart cards. Using a 3rd party storage is ideal but to be honest smart cards share the fate of PKI for complexity so many solution sets avoid tokens/smart cards, unless the policies mandate certificates.
When smart cards are more expensive/complex (readers, personalization etc) enterprises use USB tokens to store certificates. (Several companies  provide tokens with certificate support, ActivIdentity, Aladdin, Authenex, Entrust, SafeNet (merged with Aladdin) , RSA (RSA has a hybrid token for OTP + certs)).


If you would like to use smart cards as the certificate container, or use the same certs for physical security simultaneously, you can simple take one of the ready to use HSPD-12 Personal Identity Verification (PIV) Card solutions (http://fips201ep.cio.gov/apl.php) so that you can avoid designing all components architecture yourself.


Of course do it yourself path is more fun, technically it is straightforward to integrate certs with any 802.1x based authentication server but as you know it usually gets more complex. We have deployed a complete system for enrollment, biometrics, cards, CMS etc, (took 3+ years)

Best way to stop malware from spreading in a large secure network

Question :What's the best way to stop malware from spreading in a large secure network with no internet connectivity and a multi-platform environment?

Even though the secure environment has no internet access and is on a controlled environment, external USB devices have been added to the network and viruses have been introduced. I'm trying to think of the best ways to stop such external threats being added to a secure closed network. I've got a few ideas bouncing around my head as I believe Antivirus software should be deployed on the workstations in case additional methods of malware introduction are given other that USB. The USB ports could be disabled on all workstations and then the external devices could be scanned before adding to the network. But I'm sure there could be other ideas so can someone offer some suggestions?

Answer:There are multiple approaches, but “the” best way will depend on the mix of your devices in your multi-platform environment (if you still have NT4s and ancient slackware linux copies the solutions you are looking at will be different) and your network status. If there is no internet connectivity naturally you should focus more on entry points (intranets, USB, CD, Floppy, Bluetooth, IR, Wi-Fi)

If you want to classify approaches, your solutions can be at 3 levels, host based, network based and hybrid.

1- Host Based:

a. Use a comprehensive “endpoint security” solution that will have

i. Port Control (USB, CD, Floppy, Bluetooth, IR, Wi-Fi, Ethernet etc)

ii. Encryption (file, disk, mail), key/cert management

iii. Firewall

iv. IPS

v. Antivirus (http and SMTP)

vi. Antispam, Phishing, Malware control (http, SMTP, SMS)

vii. URL filtering

viii. Application control

ix. File integrity Monitoring

x. Remote device management (in a secure manner :)

xi. Biometrics/TPM/SSO/802.1x support

b. Lock down the environment. Do not allow end users to modify any system settings. (e.g. use group policies on windows environment, security blanket on Linux etc)

c. Use point solutions start with port control, anti malware, AV, IPS, firewall . Monitor system resource utilization you may kill endpoints by multiple clients

d. Get physical; super glue all USB ports, remove the CD Drives, break IR sensors, turn off the radios.

e. For old unsupported platforms, deploy file integrity monitoring on critical areas (e.g. tripwire)

f. Use a big brother monitoring tool like Raytheon Oakley’s SureView (check with legal first : )

2- Network Based:

a. Use IPS on the network. IPS will alert you on suspicious traffic you that you can take action faster. If the network traffic is encrypted, IPS will not be very helpful. You may consider decrypting traffic but the solution is a topic for another post

b. Use anomaly detection tools. I really like using these tools; they are my most favorite malware detection solutions. They can either sniff traffic over taps or get flow data. Good solutions are Q1 Labs, Mazu (now Riverbed Cascade).. But any netflow tool will help

c. Segment your network with firewalls

d. Do not allow all protocols (who needs IPX, NetBeui, AppleTalk, SNA anyway : )

e. Use ACLs on network devices. Only allow known ports, lock down network for SRC/DST APP based access rules

f. Monitor Airspace… Make sure that nothing flies out /comes in via wi-fi/Bluetooth et al. I can recommend several tools.

3- Hybrid

a. Use Network access control (NAC). You can have all the security in the world until the cable guy plugs-in his laptop to the Ethernet port in the cafeteria.

b. Use an agent-less scanning tool. Compare all hosts, applications vs your approved gold copies. Monitor all malware constantly from remote. My favorite is Promisec. But you can even use Microsoft SMS

c. Never forget the phones, the smartphones, VOIP phones are the new hosts for the virulent outbreaks/pandemic

If you have a specific question please let me know.

The "Cyber" Word

I got the following e-mail from one of my peers.
==================
From: Chris Camejo
Sent: Sunday, October 04, 2009 2:19 PM
To: ---------------------

Subject: Cyberwords
I saw this “Cybersecurity” article on CNN and the ridiculous overuse of cyberwords is good for a chuckle:
http://www.cnn.com/2009/POLITICS/10/02/dhs.cybersecurity.jobs/index.html
Apparently the government wants a “cyberczar” and more “cyberexperts” to work as “cyberanalysts” to protect “cybernetworks” from “cyberthreats” and engage in “cyberwarfare” so they can be a an effective “cyberorganization”. Yes, all of those words were really used in the article.
It scares me that there are people making decisions in government who write stuff like that.
-Chris
=====================
I could not agree more.

Every time I see an acronym or a government program that starts with “cyber” prefix I get irritated. I quickly associate the misapplication of the “cyber” prefix with ill-thought, wrong- footed, erroneous information security initiatives – cybersecurity, cyberczar, cybercop, cyberspace and the list goes on…Even my MS Word spell check doesn’t like them. This (using cyber prefix) simply takes the meaning of many serious topics that we are working on by diluting the significance, to the point of serious confusion to everyone except the small number of cyber experts : )

It is also very interesting that only state and federal agencies use “cyber”

The word cyber entered English language in 1991 as “of, relating to, or involving computers or computer networks” according to Merriam-Webster.

The reason I cannot associate cyber is that etymologically it is wrong. Cyber prefix is derived from cybernetics. Cybernetics as a concept in society has been around at least since Plato used it to refer to government. Maybe that is why the government today likes to use it. In modern times, the term became widespread because Norbert Wiener wrote a book called "Cybernetics" in 1948. The study is described as the science of communication and control theory that is concerned especially with the comparative study of automatic control systems (as the nervous system and brain and mechanical-electrical communication systems) Cybernetics is an established interdisciplinary science not a sci-fi flick or an internet buzz word (http://en.wikipedia.org/wiki/Cybernetics) ) The word comes from Greek “kybernetes” pilot, governor (from kybernan to steer, govern) + English –ics.

So what is the relationship between Internet and Cyber? I do not see a real one ..Maybe it is the cyborgs which is a combination of cybernetic + organism.

RSA Conference Notes (US 2009)

Better late than never...

During the RSA conference (April 2009) organizers had flip cameras for us (where they announced over twitter)
Instead of  typing/blogging my notes, I experienced the "vlogging" which was easy. Here are RSA edited notes from RSA Conference web site:

Part I
Part II
Part III

Sometimes it is positive to see and hear the author, sometimes it is not. But as far as I see we should better not hide behind anonymous posts. I think that we can communicate better with the new gadgets offered us literally at no cost.

IT Governance, Risk and Compliance (ITGRC) Tools August 2009

For 2011 list follow this link

Here are the updated links for the IT-GRC vendors, IT-GRC wanna be GRC vendors, and some IT based risk management tool/software providers.

There is still a thin line between IT, Financial and ERP GRC solution providers.

I have noticed that SAP has created its own GRC context where GRC means a lot of other things... SoD- Segregation of Duties, entitlements management, users access/authorization for applications/transactions, audit managment, role management etc.Basically a dull extention of IT audit controls. SAP's Virsa and SUN's Vaau acqusitions are good examples of this trend. That is not GRC -- that is mediocre IT controls audit. The term GRC is used without any consideration. This statement is also valid for the other usual suspects l(Oracle, PeopleSoft, Hyperion, JD Edwards,)

Here is a quick M&A update from last post:
Brabeion is acquired by Archer (Big News)
Controlpath is acquired by Trustwave.
Paisley is acquired by ThomsonReuters
Iconium is acquired by Logicalis
IBM dropped their own suite and working with Modulo
Favored GRC has a new name Highpoint GRC
Achiever is gone
I looked at ACL, Approva,Aveksa,Opentext,SecurityWeaver, Xpandion, Spatiq solutions,, I will be checking these vendors in the future, these solutins tend to manage ERP security only)..

Service Providers are not merchants so if you are providing card processing for 3rd parties (Payment Service Provider) PSP or if you are a TPP (Third Party Processor) PCI levels, validation and reporting requirements are different. The charts above are for merchants only.

Clouds and the VPN

Question:
Do I need VPNs in the cloud?

Answer:
There are several questions regarding the necessity of VPNs in the cloud.

I think the first step is to clear the concept of cloud. Currently the word “cloud” is used interchangeably for TelCo service provider transport clouds (Network Clouds) (e.g.MPLS) and Cloud computing web services that provide resizable compute capacity as a cloud (like Amazon EC2).. We can also define private service providers like SaaS providers, managed service providers MSPs) as cloud/utility providers (like force.com from salesforce.com, webroot SaaS). Here are some articles defining cloud and transport options.
http://www.eecs.berkeley.edu/Pubs/TechRpts/2009/EECS-2009-28.pdf
http://mediaproducts.gartner.com/reprints/f5networks/vol3/article4/article4.html


When the necessity of VPNs in the clouds are analyzed, it is obvious that encryption is indeed one of the key pillars of modern information security. And VPNs do provide confidentiality and integrity for data at transit. When cloud networks do transport the data they should provide integrity and confidentiality of data. That being said this does not have to be at layer 3 (IPSEC) or layer 6 (SSL). So focusing on an IPSEC client does not help to address the issue. Confidentiality and integrity services can also be provided via applications themselves. When data is critical you may certainly encrypt data at application layer. (e.g. rights management solutions)

Here is the high level satus for VPNs in the cloud

1- TelCo Network Clouds (Service Provider) – This is the most interesting part. TelCos claim that their shared infrastructure and MPLS VPNs are secure. This is questionable (see article below) but the answer depends on the security needed.
If service provider cloud is not trusted enough you always encrypt at another layer (usually with the application).I personally believe that cloud service provider (TelCos) must be subject to heavier inspection when they are transporting almost all of the intersite traffic. Here are some articles discussing the issue
http://www.blackhat.com/presentations/bh-europe-06/bh-eu-06-Rey-up.pdf
http://www.techworld.com/networking/features/index.cfm?featureid=3360

I also do not understand why TelCos are exempt from security regulations. (PCI is a good example) TelCos (and their admins, applications, helpdesk people, servers, cable guys…) do have access to almost all interoffice data traffic when MPLS type of TelCo backbone is used. And when the MPLS cloud is compromised, all clear text (yes even the tunneled ones) will be compromised. Real encryption is rarely used. TelCos have been promoting themselves as secure service providers while promoting layered tunnels as segmentation, but I believe they must seal these claims with 3rd party certifications and allowing encryption friendly (where keys are held by the data custodians) clouds.

2- Cloud Computing providers: These providers addressed encryption at their inception thanks to their security aware generation. Before encryption there are several other questions. Here is my post on generic cloud computing security issues: http://security.24kasim.org/2009/02/cloud-computing-security.html

3- SaaS providers. SSL looks like the king at these providers. Segregation of customer data, and customer driven/controlled encrpytion for data at rest and data at transit is required. For data at transit, SSL is secure enough when proper authentication/cert management is provided.

I am still following the following basic principles when I evaluate a platform. Regardless of the nature of technology, all platforms (clouds and others) should answer properly to following areas of information security:
1- Authentication
2- Authorization
3- Confidentiality
4- Integrity
5- Non-Repudiation
