The Ten Commandments of Encryption Policy
 
03:41
Here's something I wrote a few weeks ago and I've been spreading around, and encouraging others to do so as well. The formatted version I put on my DeviantArt journal is linked to below, and I've provided the raw text as well; feel free to copy it and spread it around anywhere you think it'll do good--especially to politicians. The Ten Commandments of Encryption Policy by shanedk on DeviantArt http://shanedk.deviantart.com/journal/The-Ten-Commandments-of-Encryption-Policy-634133886 So many politicians, bureaucrats, and pundits are proposing weakening our crypto to allow searches by law enforcement without understanding the issue, so I thought it'd be good to have a quick reference to explain why this is a bad idea. Feel free to copy this and send to politicians, news reporters, or anyone else you think needs to know this. The Ten Commandments of Encryption Policy 1. In "Applied Cryptography" (2nd Ed., John Wiley & Sons, 1996), Bruce Schneier wrote: "There are two kinds of cryptography in this world: cryptography that will stop your kid sister from reading your files, and cryptography that will stop major governments from reading your files." Therefore, anything that allows our government to read our messages will automatically put our crypto into the "kid sister" category. 2. Anything that allows government to read your message will also allow hackers to read your message. Cryptography is just math, and math works the same for everybody. It doesn't distinguish between good people and bad, or who has a warrant and who doesn't. 3. When strong crypto is outlawed, only outlaws will have strong crypto. The encryption genie is already out of its mathematical bottle. Weakening our crypto so our governments can read it will only make us vulnerable to hacker groups and terror organizations like ISIS, who will have no hesitation about breaking the law to use strong crypto themselves. 4. "If you have nothing to hide, you have nothing to worry about" is a very dangerous mantra. Just ask anyone who's had their identity stolen. 5. When people talk about giving law enforcement authorities access to our data, remember that they're talking about the same law enforcement authorities who illegally tapped Martin Luther King Jr.’s phones. 6. Terror attacks, mass shootings, and mass hackings are all proof that we cannot rely on laws to protect us. We need to protect ourselves with math. Protecting our data is too important to be left to governments. 7. Always remember that lawmakers want solutions that are visible, that they can point to and say, "See? It works." But security solutions that ACTUALLY work are invisible. People go about their lives unaware of the attacks they were protected from. People don't notice the days their house DOESN'T get burgled. 8. Don't be caught up in considering how much security you "need." You won't know how much that is until after the worst happens and it's too late. We need to be able to give ourselves every last bit of security that we can. 9. Before you bring up the founders or the Constitution, remember that they themselves often communicated using ciphers. Thomas Jefferson even invented a wheel cipher for this purpose. 10. We need to consider the consequences of constant observation. Every bit of human progress began as an idea that most people opposed. The last thing we want to do is make people afraid to express those ideas.

PCI Requirement 3.5.2 Restrict Access to Cryptographic Keys
 
01:28
PCI Requirement 3.5.2 states, “Restrict access to cryptographic keys to the fewest number of custodians necessary.” There should be very few employees who have access to your organization’s cryptographic keys. Typically, only those deemed “key custodians” have this type of access. In order to comply with PCI Requirement 3.5.2, your organization needs to maintain strict access controls around who has access to cryptographic keys in order to prevent an unauthorized user from gaining access to the encryption/decryption keys. Wherever keys reside, there needs to be strict control. Whether that’s in a safe, somewhere electronic, or backed up, an assessor will want to examine where your keys reside. An assessor will also want to see the list of users who have access to keys, and ensure that the list includes the fewest number of key custodians as possible. If you store, process, or transmit cardholder data, interact with payment card data in any way, or have the ability to impact someone else’s cardholder information or the security of that information, you are subject to comply with the PCI DSS. This exclusive video series, PCI Demystified, was developed to assist your organization in understanding what the Payment Card Industry Data Security Standard (PCI DSS) is, who it applies to, what the specific requirements are, and what your organizations needs to know and do to become compliant. Learn more at https://kirkpatrickprice.com/video/pci-requirement-3-5-2-restrict-access-cryptographic-keys/ Video Transcription If we’re encrypting cardholder data – or any other data for that matter – and somebody gains access to your encryption/decryption keys, chances are it’s game over. They can look to decrypt that data or gain access to it. PCI DSS Requirement 3.5.2 states that your organization needs to maintain strict access controls around who has access to these keys. There’s going to be several places, from an assessment perspective, that we look to see where these keys are stored. You might have them physically in a safe somewhere, we might look to see how you’re storing them electronically, we might ask how you’re backing them up. In any event, wherever these keys reside, you need to maintain strict control over those particular keys.

What is KEY DISTRIBUTION CENTER? What does KEY DISTRIBUTION CENTER mean?

What is KEY DISTRIBUTION CENTER? What does KEY DISTRIBUTION CENTER mean? KEY DISTRIBUTION CENTER meaning - KEY DISTRIBUTION CENTER definition - KEY DISTRIBUTION CENTER explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In cryptography, a key distribution center (KDC) is part of a cryptosystem intended to reduce the risks inherent in exchanging keys. KDCs often operate in systems within which some users may have permission to use certain services at some times and not at others. For instance, an administrator may have established a policy that only certain users may backup to tape. (Perhaps the administrator has concerns that unrestricted use might result in someone smuggling out a tape containing important information; but the precise reason does not matter for the purpose of explaining the functioning of the key-distribution center.) Many operating systems can control access to the tape facility via a "system service". If that system service further restricts the tape drive to operate only on behalf of users who can submit a service-granting ticket when they wish to use it, there remains only the task of distributing such tickets to the appropriately permitted users. If the ticket consists of (or includes) a key, one can then term the mechanism which distributes it a KDC. Usually, in such situations, the KDC itself also operates as a system service. A typical operation with a KDC involves a request from a user to use some service. The KDC will use cryptographic techniques to authenticate requesting users as themselves. It will also check whether an individual user has the right to access the service requested. If the authenticated user meets all prescribed conditions, the KDC can issue a ticket permitting access. KDCs mostly operate with symmetric encryption. In most (but not all) cases the KDC shares a key with each of all the other parties. The KDC produces a ticket based on a server key. The client receives the ticket and submits it to the appropriate server. The server can verify the submitted ticket and grant access to user submitting it. Security systems using KDCs include Kerberos. (Actually, Kerberos partitions KDC functionality between two different agents: the AS (Authentication Server) and the TGS (Ticket Granting Service).)

USENIX Security '17 - Phoenix: Rebirth of a Cryptographic Password-Hardening Service
 
28:41
Russell W. F. Lai, Friedrich-Alexander-University Erlangen-Nürnberg, Chinese University of Hong Kong; Christoph Egger and Dominique Schröder, Friedrich-Alexander-University Erlangen-Nürnberg; Sherman S. M. Chow, Chinese University of Hong Kong Password remains the most widespread means of authentication, especially on the Internet. As such, it is the Achilles heel of many modern systems. Facebook pioneered using external cryptographic services to harden password-based authentication in a large scale. Everspaugh et al. (USENIX Security ’15) provided the first comprehensive treatment of such a service and proposed the PYTHIA PRF-Service as a cryptographically secure solution. Recently, Schneider et al. (ACM CCS ’16) proposed a more efficient solution which is secure in a weaker security model. In this work, we show that the scheme of Schneider et al. is vulnerable to offline attacks just after a single validation query. Therefore, it defeats the purpose of using an external crypto service in the first place and it should not be used in practice. Our attacks do not contradict their security claims, but instead show that their definitions are simply too weak. We thus suggest stronger security definitions that cover these kinds of real-world attacks, and an even more efficient construction, PHOENIX, to achieve them. Our comprehensive evaluation confirms the practicability of PHOENIX: It can handle up to 50% more requests than the scheme of Schneider et al. and up to three times more than PYTHIA.

USENIX Security '17 - Extension Breakdown...
 
24:31
Extension Breakdown: Security Analysis of Browsers Extension Resources Control Policies Iskander Sanchez-Rola and Igor Santos, DeustoTech, University of Deusto; Davide Balzarotti, Eurecom All major web browsers support browser extensions to add new features and extend their functionalities. Nevertheless, browser extensions have been the target of several attacks due to their tight relation with the browser environment. As a consequence, extensions have been abused in the past for malicious tasks such as private information gathering, browsing history retrieval, or passwords theft—leading to a number of severe targeted attacks. Even though no protection techniques existed in the past to secure extensions, all browsers now implement defensive countermeasures that, in theory, protect extensions and their resources from third party access. In this paper, we present two attacks that bypass these control techniques in every major browser family, enabling enumeration attacks against the list of installed extensions. In particular, we present a timing side-channel attack against the access control settings and an attack that takes advantage of poor programming practice, affecting a large number of Safari extensions. Due to the harmful nature of our findings, we also discuss possible countermeasures against our own attacks and reported our findings and countermeasures to the different actors involved. We believe that our study can help secure current implementations and help developers to avoid similar attacks in the future. View the full program: https://www.usenix.org/sec17/program

USENIX Security '17 - Same-Origin Policy: Evaluation in Modern Browsers
 
29:10
Jörg Schwenk, Marcus Niemietz, and Christian Mainka, Horst Görtz Institute for IT Security, Chair for Network and Data Security, Ruhr-University Bochum The term Same-Origin Policy (SOP) is used to denote a complex set of rules which governs the interaction of different Web Origins within a web application. A subset of these SOP rules controls the interaction between the host document and an embedded document, and this subset is the target of our research (SOP-DOM). In contrast to other important concepts like Web Origins (RFC 6454) or the Document Object Model (DOM), there is no formal specification of the SOP-DOM. In an empirical study, we ran 544 different test cases on each of the 10 major web browsers. We show that in addition to Web Origins, access rights granted by SOPDOM depend on at least three attributes: the type of the embedding element (EE), the sandbox, and CORS attributes. We also show that due to the lack of a formal specification, different browser behaviors could be detected in approximately 23% of our test cases. The issues discovered in Internet Explorer and Edge are also acknowledged by Microsoft (MSRC Case 32703). We discuss our findings in terms of read, write, and execute rights in different access control models. View the full program: https://www.usenix.org/sec17/program

Integrity Protection and Access Control - Who Do You Trust? by Glenn Wurster, BlackBerry
 
38:33
Integrity Protection and Access Control - Who Do You Trust? - Glenn Wurster, BlackBerry Without file-system and boot integrity for all storage, on-line access control against a physical attacker is a masquerade. Using an off-line attack, an attacker can change the permissions, contents, and even the SELinux label of a file not integrity protected. What does SELinux do if it can't trust its labels? One solution is to encrypt all file-systems using hardware backed keys. In this talk I will start by talking about a LSM created for the BlackBerry Priv that ties running with elevated privileges (including SEAndroid domains) to integrity protection. The approach is designed to limit the risk of a system service executing a binary on the user data partition with elevated privileges. After talking about the specific LSM developed, I will expand the focus to the general intersection between integrity protection and access control. About Glenn Wurster Glenn Wurster is currently a Principal Security Researcher with BlackBerry. He has presented at conferences including Usenix Enigma, ACM CCS, Usenix HotSec, and IEEE S&P. He co-chaired ACM SPSM in 2015 and is on the program committee for Usenix WOOT and ACM SPSM in 2016. He is currently involved in operating system security for both Linux (as a result of his ongoing work with the Android based BlackBerry Priv smartphone) and QNX (as a result of his ongoing work with BlackBerry 10 smartphones). His current research is focused on mandatory access control and mitigations against security vulnerabilities. He received his Ph.D. in 2010, where his thesis focused on mechanisms which encouraged secure-by-default development behaviour by constraining dangerous permissions.

PCI Requirement 3.6.8 Key-Custodian Responsibilities
 
02:12
Key-custodians are one of the most important jobs within your organization. They’re responsible for creating encryption keys, altering keys, recovering keys, rotating keys, distributing keys, maintaining keys, and so much more. They are managing every aspect of the encryption of your environment. Key-custodians have the keys to your kingdom. By having key-custodians sign a formal document stating that they understand and accept their responsibilities, there is a better change for them to commit to their role. Your key-custodians must understand the gravity of the job they’ve taken, and assessors need to see some type of acknowledgement of that. If key-custodians do not perform their job correctly or securely, this affects your entire organization because it could lead to vulnerabilities and breaches. Watch the full video to learn more about PCI Requirement 3.6.8 from Jeff Wilder. If you store, process, or transmit cardholder data, interact with payment card data in any way, or have the ability to impact someone else’s cardholder information or the security of that information, you are subject to comply with the PCI DSS. This exclusive video series, PCI Demystified, was developed to assist your organization in understanding what the Payment Card Industry Data Security Standard (PCI DSS) is, who it applies to, what the specific requirements are, and what your organizations needs to know and do to become compliant. Learn more at https://kirkpatrickprice.com/video/pci-requirement-3-6-8-key-custodian-responsibilities/ Video Transcription Somebody needs to be truly responsible for managing the encryption of your environment. The individuals we typically identify as your key-custodians. These individuals need to sign a document – this signature can be electronic or it can be in writing – but effectively what we’re needing is some acknowledgment by these individuals that they truly understand the gravity of the job they’ve taken, and that they understand all of the policies and procedures and are good with it. The purpose and intent behind this is understanding that these individuals really have the keys to your kingdom. Their job, in my professional opinion, is one of the most important jobs in your environment. If they do not do their job well, or do not do it correctly or securely, that could effectively lead to the compromise of your environment. We’ve all seen what breaches in the past have done to organizations. From an assessment perspective, the assessor is going to be working with your HR department to identify who are those individuals responsible for the key management. We’re going to be asking for some artifact where they have read and understand their responsibilities as key-custodians in your environment.

PCI Requirement 3.6.6 Using Split Knowledge & Dual Control
 
03:02
PCI Requirement 3.6.6 is one requirement that both assessors and clients struggle to understand. PCI Requirement 3.6.6 states, “If manual clear-text cryptographic key-management operations are used, these operations must be managed using split knowledge and dual control.” What is split knowledge? The PCI DSS explains split knowledge as, “Split knowledge is a method in which two or more people separately have key components, where each person knows only their own key component, and the individual key components convey no knowledge of the original cryptographic key.” What is dual control? The PCI DSS defines dual control as, “Dual control requires two or more people to perform a function, and no single person can access or use the authentication materials of another.” Why use both? Although PCI Requirement 3.6.6 confuses many assessors and clients, both split knowledge and dual control must be used to comply with this requirement. The PCI DSS explains, “Split knowledge and dual control of keys are used to eliminate the possibility of one person having access to the whole key. This control is applicable for manual key-management operations, or where key management is not implemented by the encryption product.” If you store, process, or transmit cardholder data, interact with payment card data in any way, or have the ability to impact someone else’s cardholder information or the security of that information, you are subject to comply with the PCI DSS. This exclusive video series, PCI Demystified, was developed to assist your organization in understanding what the Payment Card Industry Data Security Standard (PCI DSS) is, who it applies to, what the specific requirements are, and what your organizations needs to know and do to become compliant. Learn more at https://kirkpatrickprice.com/video/pci-requirement-3-6-6-using-split-knowledge-dual-control/ Video Transcription If you’re using a clear text key management program in order to create your encryption keys, it’s required that you use split knowledge and dual control. This is one requirement that many assessors have gotten wrong for many years, including myself. This is one requirement that we see a lot of clients struggle to understand. Taking an encryption key and splitting it in half (giving half to one person and half to another), is not split knowledge and dual control. It might be dual control, but it’s not split knowledge. When we look at the definition of split knowledge and dual control, dual control means that it takes more than one individual to create this key rotation ceremony. When we look at split knowledge, it says that when we create the key, no one individual has any knowledge of the resulting key. Where you take these two key halves and one person gets one half and another person gets the other half, that one individual only knows what their half of that key is. If you are developing or using a clear text key management program, what we recommend that you do is have some “X, or…” process. You have Key Custodian A and Key Custodian B that has, if you’re going to create an 128 bit key, each individual has 128 bits of a key seed. Those two individuals come together and input their key into their application or their key seed into the application. The application then goes through a process of “X, or…” those two values together, then outputs the encryption key that nobody knows. If this is a struggle for you or you need a better understanding of what clear text management program looks like, give me a call or talk to your assessor – they’ll be more than happy to help you understand what a clear text management program really looks like.

PCI Requirement 6.4 – Follow Change Control Processes & Procedures for Changes to System Components
 
02:23
Learn more at https://kirkpatrickprice.com/video/pci-requirement-6-4-follow-change-control-processes-procedures-changes-system-components/ Most, if not all, security programs require that you have some type of Change Control Program. At the start of our PCI Demystified journey, we discussed Change Control Programs. In PCI Requirement 6.4, this point is reiterated. PCI Requirement 6.4 states, “Follow change control processes and procedures for all changes to system components.” Your organization should have the appropriate methods to control any changes into and out of your environment. Your organization’s Change Control Program should include a documented roll-back plan, a testing phase, management’s approval, and updated documentation. The PCI DSS warns, “Without properly documented and implemented change controls, security features could be inadvertently or deliberately omitted or rendered inoperable, processing irregularities could occur, or malicious code could be introduced.” A documented roll-back plan is crucial to your Change Control Program. This documentation should outline exactly how to roll-back changes in the event that something goes wrong or there’s a negative impact. All changes need to be tested to ensure there is no negative impact on the cardholder data environment. Testing the roll-back plan shows an assessor your organization’s level of maturity. Management needs to approve all aspects of the Change Control Program. Any time there is a significant change within your environment, you must ensure that all documentation is updated, including network diagrams, dataflow diagrams, and inventory lists. Until documentation is update, the change control should be left open. Development and testing environments must be separate from production environments, plus there needs to be access control in place to enforce this separation. A separation of duties must exist between the employees assigned to the development and testing environments and those assigned to the production environment. Production data (live PANs) cannot be used for testing or development and, vice versa, test data should be removed before a system or application goes into production. Change control procedures related to security patches and software modifications must be documented. It’s vital to follow change control processes and procedures for all changes to system components. If not, according to the PCI DSS, security features could be unintentionally or deliberately omitted or rendered inoperable, processing irregularities could occur, or malicious code could be introduced.

Crafting a cyber security strategy that is simple enough to actually be implemented, yet nuanced enough to be effective is no easy task. By reconciling IT security solutions’ prioritization of confidentiality against ICS’s prioritization of availability, this session will present the principles that a successful cyber security policy can be built around. This requires an understanding of the threats ICS will face in terms of probability, not possibility, which includes an explanation of how current ICS strategies fail. Policy foundations will then be presented that allow proven IT security strategies to be successfully applied to ICS legacy networks. Description

High Performance BGP Security: Algorithms and Architectures
 
44:47
Speakers: Mehmet Adalier, Antara Teknik LLC KOTIKALAPUDI SRIRAM, National Institute of Standards and Technology The BGPsec protocol addresses several vulnerabilities associated with BGP. In particular, it provides cryptographic protection against prefix mis-originations and AS path attacks. However, the required cryptographic processing imposes additional workload on the route processor in edge routers. In this talk, we first provide an insight into the nature of computational complexities associated with BGPsec update processing. We then propose and evaluate optimizations for BGPsec update processing, including algorithmic, field level, and group level optimizations. We quantify the impact of these optimizations on BGPsec processing at the core cryptographic operations level as well as at the update message processing level. ECDSA signing and verification speeds with the proposed enhancements are compared against the fastest available OpenSSL implementation for the same. Further, we also report results on the speed of BGPsec update processing including the essential BGPsec functions such as data assembly, packet parsing, sorting AS path segments, fetching public keys, and executing ECDSA P256 signing and verification. Finally, we make use of reasonable projections for IPv4 and IPv6 growth rates, BGPsec adoption rate, and processor speedup, and present a model for BGPsec routing convergence time. This model considers BGPsec processing as incremental to the basic BGP processing, which includes best path selection, route filtering, applying policy filters, etc. A relative comparison is provided for convergence time projections for the BGP only scenario vs. mixed (BGP + BGPsec) scenario, which assumes that BGPsec adoption takes about two decades to go from zero to nearly complete global adoption.

A Cryptographic Compiler for Information-Flow Security
 
58:36
Joint work with Tamara Rezk and Gurvan le Guernic (MSR-INRIA Joint Centre http://msr-inria.inria.fr/projects/sec) We relate two notions of security: one simple and abstract, based on information flows in programs, the other more concrete, based on cryptography. In language-based security, confidentiality and integrity policies specify the permitted flows of information between parts of a system with different levels of trust. These policies enable a simple treatment of security, but their enforcement is delicate. We consider cryptographic enforcement mechanisms for distributed programs with untrusted components. Such programs may represent, for instance, distributed systems connected by some untrusted network. We develop a compiler from a small imperative language with locality and security annotations down to cryptographic implementations in F#. In source programs, security depends on a policy for reading and writing the shared variables. In their implementations, shared memory is unprotected, and security depends instead on encryption and signing. We rely on standard primitives and hypotheses for cryptography, stated in terms of probabilistic polynomial-time algorithms and games. Relying on a new type system, we show that our compiler preserves all information-flow properties: an adversary that interacts with the trusted components of our code and entirely controls its untrusted components gains illegal information only with negligible probability.

USENIX Security '18 - Rethinking Access Control and Authentication for the Home Internet of Things
 
24:34
Rethinking Access Control and Authentication for the Home Internet of Things (IoT) Weijia He University of Chicago Maximilian Golla Ruhr-University Bochum Abstract: Computing is transitioning from single-user devices to the Internet of Things (IoT), in which multiple users with complex social relationships interact with a single device. Currently deployed techniques fail to provide usable access-control specification or authentication in such settings. In this paper, we begin reenvisioning access control and authentication for the home IoT. We propose that access control focus on IoT capabilities (i.e., certain actions that devices can perform), rather than on a per-device granularity. In a 425-participant online user study, we find stark differences in participants' desired access-control policies for different capabilities within a single device, as well as based on who is trying to use that capability. From these desired policies, we identify likely candidates for default policies. We also pinpoint necessary primitives for specifying more complex, yet desired, access-control policies. These primitives range from the time of day to the current location of users. Finally, we discuss the degree to which different authentication methods potentially support desired policies.
