01:12:01
Listen to the Podcast (audio) version: https://goo.gl/grtBfJ Bruce Schneier is a fellow and lecturer at the Harvard Kennedy School and the Berkman-Klein Center for Internet and Society. He is a special advisor to IBM Security and a board member of the Electronic Frontier Foundation, Access Now, and the Tor Project. You can find him on Schneier.com and on twitter at @schneierblog He is the author of Data and Goliath, Applied Cryptography, Liars and Outliers, Secrets and Lies, and Beyond Fear: Thinking Sensibly about Security in an Uncertain World. His new book is Click Here to Kill Everybody, which we discuss at length, as well as: • How to protect yourself from being hacked and what to do if you are hacked • Why companies do not invest more in software security • The motivation of hackers: money, power, fun • The probability of your car being hacked and driven into a wall • The probability of planes being hacked and felled from the sky • Edward Snowden and Wikileaks: hero or villain • The Pentagon Papers and Daniel Ellsberg • What would happen if the electrical grid was hacked • Cyberdeaths (homicides done remotely over the Internet) and how the government will respond with regulations when it does • If the government were to set a policy for the security level of an IoT device that can kill people, is there a maximum allowed probability that it could be hacked? • The North Korean hack of Sony • The Russian hack of the 2016 election and how to prevent that from happening again • Why we’re still using paper ballots in our voting system rather than computers and ATMs like banks use. • The lessons of Y2K for the coming AI apocalypse • What keeps him up at night This dialogue was recorded on January 21, 2019 as part of the Science Salon Podcast series hosted by Michael Shermer and presented by The Skeptics Society, in California.

Whispers in the Hyper-space: High-speed Covert Channel Attacks in the Cloud
 
30:05
This video is part of the Infosec Video Collection at SecurityTube.net: http://www.securitytube.net Whispers in the Hyper-space: High-speed Covert Channel Attacks in the Cloud Slide : - https://www.usenix.org/system/files/conference/usenixsecurity12/sec12-final97.pdf Information security and privacy in general are major concerns that impede enterprise adaptation of shared or public cloud computing. Specifically, the concern of virtual machine (VM) physical co-residency stems from the threat that hostile tenants can leverage various forms of side channels (such as cache covert channels) to exfiltrate sensitive information of victims on the same physical system. However, on virtualized x86 systems, covert channel attacks have not yet proven to be practical, and thus the threat is widely considered a .potential risk.. In this paper, we present a novel covert channel attack that is capable of high-bandwidth and reliable data transmission in the cloud. We first study the application of existing cache channel techniques in a virtualized environment, and uncover their major insufficiency and difficulties. We then overcome these obstacles by (1) redesigning a pure timing-based data transmission scheme, and (2) exploiting the memory bus as a high-bandwidth covert channel medium. We further design and implement a robust communication protocol, and demonstrate realistic covert channel attacks on various virtualized x86 systems. Our experiments show that covert channels do pose serious threats to information security in the cloud. Finally, we discuss our insights on covert channel mitigation in virtualized environments.

SSH Configuration on Cisco Router
 
01:05:17
How to configure ssh in gns3 step by step....SSH uses public-key cryptography to authenticate the remote computer and allow it to authenticate the user, if necessary.There are several ways to use SSH; one is to use automatically generated public-private key pairs to simply encrypt a network connection, and then use password authentication to log on.Another is to use a manually generated public-private key pair to perform the authentication, allowing users or programs to log in without having to specify a password. In this scenario, anyone can produce a matching pair of different keys (public and private). The public key is placed on all computers that must allow access to the owner of the matching private key (the owner keeps the private key secret). While authentication is based on the private key, the key itself is never transferred through the network during authentication. SSH only verifies whether the same person offering the public key also owns the matching private key. In all versions of SSH it is important to verify unknown public keys, i.e. associate the public keys with identities, before accepting them as valid. Accepting an attacker's public key without validation will authorize an unauthorized attacker as a valid user. SSH provides a secure channel over an unsecured network in a client–server architecture, connecting an SSH client application with an SSH server.The protocol specification distinguishes between two major versions, referred to as SSH-1 and SSH-2. The standard TCP port for SSH is 22. SSH is generally used to access Unix-like operating systems, but it can also be used on Windows. Windows 10 uses OpenSSH as its default SSH client. #ssh #networkingguruji #cisco #gns3 How to configure ip address in cisco router..... http://shrinkybee.com/txW8PV How to add virtual pc in gns3.... http://shrinkybee.com/tqRmeWa console cable..... http://shrinkybee.com/KwVjl http://shrinkybee.com/HtFDqg http://shrinkybee.com/9J2SPpes Online class Registration Form..... http://shrinkybee.com/7beK putty download link.... http://shrinkybee.com/QZgkyPl4 hyper terminal..... http://shrinkybee.com/aQ31kDH How to configure telnet in gns3 http://shrinkybee.com/ykQKsSn ................................................................................................................ #networkingguruji #ssh #cisco #NETWORKINGGURUJI ...............................................................................................................

Quantum Secure Network
 
03:03
http://www.QuantumSecureNetwork.com Contact: Ken Howard @ 703-626-0690 Civilization is on the cusp of a major disruption in information technology. One that has game-changing potential for just about everything we do: the way we do business, the way we communicate, even the way we meet our basic needs. What makes this disruption different is a decided shift toward the empowerment of the individual, and away from “providers.” A shift to where individual freedom and privacy will start to matter more than convenience and reliability. There will be 1.84 billion mobile devices in 2020 and 14.4 trillion IoT market by 2022. In the midst of this growth, CyberStealth is positioned to be the quantum cyber security solution. Our Team is in the final phases of building a secure phone that will be ready Q1 2018 and StealthCrypto® NAS Container, a hybrid of a NAS unit and Wi-Fi Router that will create a quantum meshed network for data storage, mining, IoT communication, authentication, and telecommunications. the StealthCrypto® Phone™, an ultra-secure mobile phone that is the first open source blockchain smartphone and NAS Units. The smartphone features hard kill switches, empowering its users to take back control of their privacy. All phones feature a built-in privacy control center giving users full access and function control on their phone. Stealth Grid™ is building adecentralized global meshed network – StealthCrypto® that adopts the sharing economy model for network access, creating communications that provide an economic incentive that allows users to share their unused data storage, bandwidth, or mine for profit. Monetizing the free exchange of data storage and bandwidth, via a secondary market, allows for free market forces to drive network growth where it is most needed. StealthCrypto® will also leverage their quantum mesh network technology to build a decentralized IoT and communication’s future. A quantum mesh network is a network topology in which each node is capable of relaying data for others and utilizing a proprietary end-to-end quantum security encryption algorithm and authentication that is dynamic. With a hyper-dimensional model, data is not only moving from block chain nodes and servers, but is also creating a more complex Hilbert space with hyper dimensional models and overlay patterns. All mesh network nodes cooperate, and with each participating node, the reach, throughput and resilience of the network is strengthened. These applications will shift the balance of power away from centralized authorities in the field of communications, data storage, currency, business, and even politics and law. Stealth Grid™’s platform is building the world’s largest fully decentralized, incentivized, self-sustainable, wireless mesh telecommunications and data storage network using blockchain technology. By marrying StealthCryptoCloud™ and StealthCrypto® unified communication applications, StealthCrypto® Smartphone ™, storage and a StealthCrypto® quantum meshing network with a StealthCrypto® Utility Token Offering, we bring unequalled, private, unified encrypted communication, telecommunications, data storage, IoT meshed devices (M2M), and authentication to support wallet-oriented micropayment systems, secure contracts, and securely manage transactions. This provides resilience against attacks on the communication servers by replacing them with decentralized StealthCrypto® nodes which anyone can host, and thus receive StealthCrypto® coins as compensation. The StealthCrypto® meshed network will enable universal access to high-speed broadband for all. To achieve this, we have an ambitious, yet realistic, vision of building the world’s largest decentralized, community distributed, data storage and telecommunications network based on blockchain technology. The secure, unified meshed communications network is therefore owned and operated by no single entity, rendering attacks on hosts ineffective

Virtual Machine Reset Vulnerabilities; Subspace LWE; Cryptography Against Continuous Memory Attacks
 
02:26:01
Virtual Machine Reset Vulnerabilities and Hedged Cryptography Tom Ristenpart, UC San Diego Virtual machines are widely used to, for example, support cloud computing services and improve home desktop security. In this talk I'll present recent work on showing a new class of vulnerabilities, termed VM reset vulnerabilities, that arise due to reuse of VM snapshots. A snapshot is the saved state of a VM, which can include caches, memory, persistent storage, etc. A reset vulnerability occurs when resuming two or more times from the same VM snapshot exposes security bugs. I'll report on our discovery of several reset vulnerabilities in modern browsers used within commonly-used VM managers. These vulnerabilities exploit weaknesses in cryptographic protocols when confronted with reused randomness. I'll then explore a new framework of hedged cryptography, which aims to build into cryptographic protocols mechanisms that provide improved security in the face of reset (or other) vulnerabilities. Subspace LWE Krzysztof Pietrzak, CWI The (decisional) learning with errors (LWE) problem asks to distinguish 'noisy' inner products of a secret vector with random vectors from uniform. The presumed hardness of this and the related learning parity with noise (LPN) problem has found many applications in cryptography. Its appeal stems from the fact that it is provably as hard as well studied worst-case lattice problems [Regev'05]. We introduce (seemingly) much stronger *adaptive* assumptions SLWE and SLPN (S for 'subspace'), where the adversary can learn inner products of the secret and random vectors after they were projected into an adaptively and adversarially chosen subspace. We prove that SLWE/SLPN mapping into subspaces of dimension N are almost as hard as the standard LWE/LPN assumptions using secrets of length N. This implies that the standard LWE/LPN problems are surprisingly robust with respect to tampering with the secret and/or the randomness used to generate the samples. This robustness directly translates to stronger security guarantees (e.g. it implies security against a broad class of related-key attacks) one can give for cryptosystems proven secure under the standard LWE/LPN assumptions. We also present a new very simple and efficient authentication protocol which is secure against active attacks under the SLPN (and thus the standard LPN) assumption. Our protocol improves upon the HB+ protocol [Juels and Weis'05],[Katz, Shin'05] (which is the best known protocol based on LPN achieving active security) in term of round complexity (optimal two rounds compared to three) and a tight security reduction. Cryptography Against Continuous Memory Attacks Yevgeniy Dodis, New York University We say that a cryptographic scheme is Continuous Leakage-Resilient (CLR), if it allows users to refresh their secret keys, using only fresh local randomness, such that: -- The scheme remains functional after any number of key refreshes, although the public key never changes. Thus, the 'outside world' is neither affected by these key refreshes, nor needs to know about their frequency. -- The scheme remains secure even if the adversary can continuously leak arbitrary information about the current secret-key of the system, as long as the amount of leaked information is bounded in between any two successive key refreshes. There is no bound on the total amount of information that can be leaked during the lifetime of the system. In this work, we construct a variety of practical CLR schemes, including CLR one-way relations, CLR signatures, CLR identification schemes, and CLR authenticated key agreement protocols. For each of the above, we give general constructions, and then show how to instantiate them efficiently using a well established assumption on bilinear groups, called the K-Linear assumption.

MCITP 70-640: Default Local Groups
 
15:45
Default local groups exist locally on a Windows computer and available only on that computer. This video looks at the local groups that are created by default on every Windows 7 and Windows Server 2008 operating system. Demonstration 10:17 Administrators 1:30 Users 2:10 Power Users 3:26 Guests 4:43 Backup Operators 5:32 Remote Desktop Users 5:53 Offer Remote Assistance Helpers 6:24 Network Configuration Operators 7:05 Performance Monitor Users 7:28 Performance Log Users 7:56 IIS_IUSRS 8:08 Replicator 8:45 Distributed COM Users 9:17 Cartographic Operators 09:39 Administrators Any user added to this group has full control over that computer. By default, the administrator will have access to everything, for example all files and folders. If an administrator has been denied access they can take ownership of the object in question and give themselves permissions to the object. Users This group is designed for the general user. It allows them to run software and change settings that relate to them. Power Users The power users group was introduced in Windows XP to give the user more access than the user group but less than an administrator. In Windows Vista this group was removed and in Windows 7 it was added again. In Windows 7, the Power Users group does not provide any access other than user access and is included only for legacy reasons. If you want to give this group the same permissions as Windows XP, you can apply a security template as explained below. This security template should only be applied as a last resort. The process is not reversible and may not function as expected with newer software. To apply the security template to the Power Users Group 1. Open mmc and add the snap-in Configuration and Security Analysis 2. Right click Security Configuration and Analysis and select open database 3. Enter a new database name or open an existing database 4. When prompted open c:\windows\inf\puwk.inf. If not prompted, right click Security Configuration and Analysis and select open template 5. Right click Security Configuration and Analysis and select configure computer now Guests The guest group gives the user the ability to login and run software. Any changes that are made by that user, for example changing the wallpaper, will be lost when the user logs off. The guest account is usually used for computers that are set up as kiosks. In this case, you want the user to have access to run software and make changes if they need to, but when the next user uses the computer, you want to ensure that the new user gets the default settings and not the modified settings.
