Symmetric Key and Public Key Encryption
 
06:45
Modern day encryption is performed in two different ways. Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. Using the same key or using a pair of keys called the public and private keys. This video looks at how these systems work and how they can be used together to perform encryption. Download the PDF handout http://itfreetraining.com/Handouts/Ce... Encryption Types Encryption is the process of scrambling data so it cannot be read without a decryption key. Encryption prevents data being read by a 3rd party if it is intercepted by a 3rd party. The two encryption methods that are used today are symmetric and public key encryption. Symmetric Key Symmetric key encryption uses the same key to encrypt data as decrypt data. This is generally quite fast when compared with public key encryption. In order to protect the data, the key needs to be secured. If a 3rd party was able to gain access to the key, they could decrypt any data that was encrypt with that data. For this reason, a secure channel is required to transfer the key if you need to transfer data between two points. For example, if you encrypted data on a CD and mail it to another party, the key must also be transferred to the second party so that they can decrypt the data. This is often done using e-mail or the telephone. In a lot of cases, sending the data using one method and the key using another method is enough to protect the data as an attacker would need to get both in order to decrypt the data. Public Key Encryption This method of encryption uses two keys. One key is used to encrypt data and the other key is used to decrypt data. The advantage of this is that the public key can be downloaded by anyone. Anyone with the public key can encrypt data that can only be decrypted using a private key. This means the public key does not need to be secured. The private key does need to be keep in a safe place. The advantage of using such a system is the private key is not required by the other party to perform encryption. Since the private key does not need to be transferred to the second party there is no risk of the private key being intercepted by a 3rd party. Public Key encryption is slower when compared with symmetric key so it is not always suitable for every application. The math used is complex but to put it simply it uses the modulus or remainder operator. For example, if you wanted to solve X mod 5 = 2, the possible solutions would be 2, 7, 12 and so on. The private key provides additional information which allows the problem to be solved easily. The math is more complex and uses much larger numbers than this but basically public and private key encryption rely on the modulus operator to work. Combing The Two There are two reasons you want to combine the two. The first is that often communication will be broken into two steps. Key exchange and data exchange. For key exchange, to protect the key used in data exchange it is often encrypted using public key encryption. Although slower than symmetric key encryption, this method ensures the key cannot accessed by a 3rd party while being transferred. Since the key has been transferred using a secure channel, a symmetric key can be used for data exchange. In some cases, data exchange may be done using public key encryption. If this is the case, often the data exchange will be done using a small key size to reduce the processing time. The second reason that both may be used is when a symmetric key is used and the key needs to be provided to multiple users. For example, if you are using encryption file system (EFS) this allows multiple users to access the same file, which includes recovery users. In order to make this possible, multiple copies of the same key are stored in the file and protected from being read by encrypting it with the public key of each user that requires access.

Mobile: (0) 9952649690 , Email: [email protected], web: www.jpinfotech.org Blog: www.jpinfotech.blogspot.com Key logging-resistant Visual Authentication Protocols The design of secure authentication protocols is quite challenging, considering that various kinds of root kits reside in PCs (Personal Computers) to observe user’s behavior and to make PCs untrusted devices. Involving human in authentication protocols, while promising, is not easy because of their limited capability of computation and memorization. Therefore, relying on users to enhance security necessarily degrades the usability. On the other hand, relaxing assumptions and rigorous security design to improve the user experience can lead to security breaches that can harm the users’ trust. In this paper, we demonstrate how careful visualization design can enhance not only the security but also the usability of authentication. To that end, we propose two visual authentication protocols: one is a one-time-password protocol, and the other is a password-based authentication protocol. Through rigorous analysis, we verify that our protocols are immune to many of the challenging authentication attacks applicable in the literature. Furthermore, using an extensive case study on a prototype of our protocols, we highlight the potential of our approach for real-world deployment: we were able to achieve a high level of usability while satisfying stringent security requirements.

What is digital signature?
 
05:03
A digital signature is equivalent to a handwritten signature in paper, and a digital signature serves three basic purposes. Digital signature is commonly used for software distribution, financial transactions and other cases where it is important to detect forgery. Digital signatures are very popular with e-mail users. In this video, I will talk about the digital, uses, and the whole process of creating and sending digitally signed document over the Internet. Keep in mind, digital signature is not about encrypting document, just like paper-based signature.

What are certificates?
 
15:11
Certificates are used to prove identity and used for creating secure communication. Check out http://itfreetraining.com for more of our always free training videos. This video looks at how a certificate works, what is a certificate and how they are used for identification and secure communication. Download the PDF handout http://itfreetraining.com/Handouts/Certificates/WhatAreCertificates.pdf What is a certificate? A certificate is an electronic document that contains data fields. When compared to a traditional paper certificate there are some similarities between an electronic certificate and a physical certificate. Digital certificates like a physical certificate are issued by an authority. For example, a university may issue a certificate to a student to show that they have completed the necessary work in order to graduate. The next question is, would you trust a physically certificate? Digital certificates work the same way. They are issued from an authority and the question becomes would you trust the authority that issued the certificate? Electronic certificates also contain other fields like who or what the certificate was issued to, how long it is valid, the public key and the digital signature. If a digital certificate is presented to a user or computer, the user or computer is able to check the certificate to ensure the person using it should be using it. Also the certificate contains a digital signature which allows the certificate to be checked to make sure it has not been modified. Digital Signature A digital signature provides a method for a certificate to be checked to ensure it has not been modified. In order to do this, a hash value is created for the certificate. To generate a hash value the certificate is put through a function to create a single value. Hash functions are designed so different certificates will not produce the same value, however the hash value cannot be used to generate the original certificate. The same principal applies to a person's fingerprints. They can be used to identify a person, however using a finger print you could not work out the features of a person like what color hair they have. When a certificate is created, the hash value for that certificate is also created. Using a function involving the private key, a digital signature is created and added to the certificate. Digital Signature Example When a certificate is used, in order to check the certificate has not been changed, the following is done: The computer generates the hash value for the certificate. Next, the digital signature is put through a function using the public key which should result in the same hash value. If both values match, the certificate has not been modified. This prevents a 3rd party taking a certificate, changing the values in the certificate and using the certificate. Trust Model Certificates work off a trust model. An example of a trust model in computers is that a computer may have a sticker on it indicating which operating systems it will run. The consumer, seeing this sticker, must trust that the manufacture would not put this sticker on the laptop unless it will run that operating system. The customer must also trust the creator of that operating system would not allow a computer manufacturer to put a sticker on a computer that would not run that operating system. Certificate Trust Model Certificates are generally deployed in a hierarchy. At the top is the root certificate authority. This can be an internal Certificate Authority or an external authority like VeriSign. When an authority like VeriSign issues a certificate, they will perform a number of checks on the individual purchasing the certificate to ensure that they are a valid business. When a certificate is used it can be checked to see which authority issued that certificate. In order for the certificate to be used, the computer must trust the authority that it was issued from. Authorities like VeriSign are trusted by default on most operating systems. Certificate Error If a certificate is presented to the computer and it is not trusted, the computer will generate an error asking if the users want to trust the certificate. It is up to the user to decide if they believe the certificate is valid. Certificate Hierarchy Certificates use a hierarchy. At the top is the root CA, below these are subordinate CA's. Any level can issue certificates to subordinate CA's or direct to users, computers or devices. If the user, computer or device trusts the root CA, then any certificate that is issued by any CA in the hierarchy will automatically be trusted and thus used by the client.

Network and cybersecurity consist of practice and policies to prevent unauthorized access to network or misuse or modification of computer network. Network and cybersecurity work on both public and private network. Network and Cybersecurity revolve around authenticating users and only allowing the real user to access data for which the data is made for. Network security covers the variety of computer network both public and private Network security starts with authenticating just one detail i.e. username +password is termed as one-factor authentication in the network and cybersecurity in two-factor authentication, something that user "has" is also used like OTP, mobile number Network and cyber security also have three-factor authentication which is something that user "is" is used eh fingerprint In network and cyber security communication between two hosts using a network may be encrypted to maintain privacy In network and cybersecurity, honeypots are used i.e. event meant as a distraction can be deployed in the network as early-warning tools, honeypots encourage attackers to spend their time and energy on decoy server while distracting their attention on real server

HTTP Basic Authentication Review with Wireshark
 
03:19
Basic HTTP Authentication Review check out the LMTV show i did covering the article https://www.youtube.com/watch?v=u4kgwFf6j8o One of the things I keep my eyes peeled for are items that involve security implications. Full disclaimer, I am not a security guru, nor do I profess to be one but I do understand some of the more obvious issues. For example many of you are probably familiar with the term ‘clear text’. This is when you data or credentials are transmitted in a text format. Obviously this is not a good thing since anyone who happens to intercept this data will be able to easily see your data or credentials. Hence the introduction of encryption when your data is encoded in such a manner that only authorized applications can read the data. Unfortunately as many people know, different types of encryption have their weaknesses. In this video I cover the most simplest of http authentication; HTTP Basic. With this method, your data is encoded with Base64 in transit. Some people even go as far as stating this is encrypted, but I don’t want to go down that rabbit hole. Suffice to say that we can all agree the data is no longer in clear text. I show you that with Wireshark, and no additional downloads, plugins or scripts, Wireshark will decode the Authorization string, revealing the credentials. The syntax presente3d is simply username:password. Please keep in mind that this something specific to Wireshark, so you should take a moment to try your own protocol analyzer to see how it fairs.

MCITP 70-640: Security Configuration Wizard
 
15:46
Check out http://YouTube.com/ITFreeTraining or http://itfreetraining.com for more of our always free training videos. The Security Configuration Wizard is a simple wizard that allows the administrator to tighten up security in Windows. This video looks how to run the wizard and configure the settings on multi computers. Download Handout http://ITFreeTraining.com/handouts/70-640/part3/securityconfigurationwizard.pdf Attack Surface The attack surface on a computer system or device is the amount of software, protocols and ports that are open for use. If an exploit was found in any of these, an attacker could potentially use these to compromise the system. To reduce the attack surface, any software, protocols or ports that are not in use should be removed or disabled. Even if an exploit is not known today, tomorrow an exploit could be found that could be used to compromise your system. A firewall should also be used to increase the security of the system. Products like Security Configuration Wizard analyze Windows and gives the administrator configuration options that they can use to improve the security of their system. The process of increasing the security of a system is also known as hardening. Demonstration Security Configuration Wizard is available from the start menu under Administrative Tools. If you have additional software on the system that opens ports, you should run this software before you start the wizard so the wizard can detect these open ports. The wizard will then go through different areas of the system list below. Role-Based Service Configuration: Analyzes security settings depending on what roles are installed on the server. If you plan to add the role later, tick the option so the wizard can suggest settings for you. Network Security: Settings regarding network security like firewall settings. Registry Settings: Basic registry settings relating to authentication and security options for file sharing. Audit Policy: Configures auditing settings to best audit changes to the system. There is also an option to apply an additional security template. This will greatly increase the security of your system. If you want to remove the settings applied from a security template later on you will need to use the roll back feature found at the start of the wizard. Once you finish the wizard, these settings can be saved and applied to any computer. The complete security template can be converted to a Group Policy Object using the following command. scwcmd transform /p:(XMLFile) /g:(GPOName)

As briefly mentioned at 7:04 , there are encryption schemes that can be run on regular computers that can't be broken by quantum computers. CORRECTIONS: [2:18] Technically, you can use any key to encrypt or decrypt whatever you want. But there's a specific way to use them that's useful, which is what's shown in the video. [5:36] In RSA, depending on exactly what you mean by "private key", neither key is actually derivable from the other. When they are created, they are generated together from a common base (not just the public key from the private key). But typically, the file that stores the "private key" actually contains a bit more information than just the private key. For example, in PKCS #1 RSA private key format ( https://tools.ietf.org/html/rfc3447#appendix-A.1.2 ), the file technically contains the entire public key too. So in short, you technically can't get the public key from the private key or vice versa, but the file that contains the private key can hold more than just the private key alone, making it possible to retrieve the public key from it.

IAME - TRANSACTION IDENTIFICATION PROTOCOL!

The IAME identity network is a decentralized identification system created for the Blockchain ecosystem. So, from the first reading, you say that nothing concrete is not clear from this sentence, but let's figure it out. IAME is the identification system for the Blockchain P2P transaction. IAME relies on its own fragmented (fragment-based) identification algorithm, according to which identity documents are fragmented into thousands of illegible parts, and the verification process is decomposed to hundreds of thousands of people. The IAME identity network consists of: a client, a distribution server, a verification server, a write block chain, an identity server. :::::::::::::::::::::::::::::::::::::::: ⚡ WEB: https://iame.io/ ⚡ WHITEPAPER: https://iame.io/res/180301-IAME-White-Paper-en.pdf ⚡ TELEGRAM: https://t.me/IAME_identity ⚡ TWITTER: https://twitter.com/@iameidentity ⚡ FACEBOOK: https://www.facebook.com/IAMEIdentity/ ⚡ MEDIUM: https://medium.com/@IAMEIdentity ⚡ LINKEDIN: https://www.linkedin.com/company/iameidentity ⚡ VIMEO: https://vimeo.com/iameidentity ⚡ GITHUB: https://github.com/iameidentity :::::::::::::::::::::::::::::::::::::::: 🐦My Bitcointalk Username: korolev3245137 🐦My Bitcointalk URL: https://bitcointalk.org/index.php?action=profile;u=1952926 🐦My ETH Address: 0x4C8a59eA64760fC276Ec8472B39C542eA20E686E 🐦My Telegram: @korolev32

Glenn Greenwald: Edward Snowden, NSA, Activism, Democracy & Freedom
 
25:03
In this speech, Glenn Greenwald reveals his experience with Edward Snowden and Laura Poitras in 2013 at Hong Kong before they revealed the highly classified NSA documents to the public. Greenwald also talks about the history of activism and pays tribue to personalities such as Rosa Park, Hans and Sophie Scholl. Other topics that he surfaces in-depth include the reaction of the US government to these revelations, signficance of Edward Snowden's courage & the challenges that we face in the future. BIO: Glenn Edward Greenwald is an American lawyer, journalist and author. In June 2013 Greenwald became widely known after The Guardian published the first of a series of reports detailing United States and British global surveillance programs, based on classified documents disclosed by Edward Snowden. The series on which Greenwald worked along with others won the 2014 Pulitzer Prize for Public Service. His reporting on the National Security Agency (NSA) won numerous other awards around the world, including top investigative journalism prizes from the George Polk Award for National Security Reporting,the 2013 Online Journalism Awards, the Esso Award for Excellence in Reporting in Brazil for his articles in O Globo on NSA mass surveillance of Brazilians (becoming the first foreigner to win the award), the 2013 Libertad de Expresion Internacional award from Argentinian magazine Perfil, and the 2013 Pioneer Award from the Electronic Frontier Foundation. His work on the NSA files was in part the subject of the film Citizenfour, which won the 2014 Academy Award for Best Documentary. Greenwald appeared onstage at the Oscar ceremony with the film's director, Laura Poitras, as she accepted the award.

BSides DC 2018 - Bypassing Port-Security In 2018: Defeating MacSEC and 802.1x-2010
 
51:12
Existing techniques for bypassing wired port security are limited to attacking 802.1x-2004, which does not provide encryption or the ability to perform authentication on a packet-by-packet basis [1][2][3][4]. The development of 802.1x-2010 mitigates these issues by using MacSEC to provide Layer 2 encryption and packet integrity checks to the protocol [5]. Since MacSEC encrypts data on a hop-by-hop basis, it successfully protects against the bridge-based attacks pioneered by the likes of Steve Riley, Abb, and Alva Duckwall [5][6]. In addition to the development of 802.1x-2010, improved 802.1x support by peripheral devices such as printers also poses a challenge to attackers. Gone are the days in which bypassing 802.1x was as simple as finding a printer and spoofing address, as hardware manufacturers have gotten smarter. In this talk, we will introduce a novel technique for bypassing 802.1x-2010 by demonstrating how MacSEC fails when weak forms of EAP are used. Additionally, we will discuss how improved 802.1x support by peripheral devices does not necessarily translate to improved port-security due to the widespread use of weak EAP. Finally, we will consider how improvements to the Linux kernel have made bridge-based techniques easier to implement and demonstrate an alternative to using packet injection for network interaction. We have packaged each of these techniques and improvements into an open source tool called Silent Bridge, which we plan on releasing at the conference.
