AAA framework and RADIUS
 
05:50
AAA stands for Authentication, Authorization, and Accounting. It is a fundamental security framework for controlling a user’s access to a network, determining access levels or user privileges based on policies and user identity, and keeping track of the user’s activities. RADIUS stands for Remote Authentication Dial-In User Service. It is a client/server protocol and system that enables a network access server, or NAS, to communicate with a central server to authenticate dial-in users, authorize their access to the network, and keeps track of their activities. Keywords: AAA, Authentication, Authorization, and Accounting, RADIUS, Remote Authentication Dial-In User Service, supplicant, network access server, NAS, Remote Access server, WAP, Wireless Access Point.

A protocol is a set of rules. It describes the proper protocol for certain actions and behaviors. David Johnston, the Governor General of Canada, broke protocol when he touched Queen Elizabeth II on the steps of Canada House on Trafalgar Square in London. The Queen was 91 years old at the time and the Governor General touched her arm to protect her from falling on the steps. It is protocol to not touch a member of Britain’s royal family. methods. Specific topics include: 1. Overview of communications channels used in power systems. 2. Review of cryptographic protocols and how they work. 3. How cryptography can impact monitoring, control, and protection communications. 4. Differences between substation communications systems and corporate The confidentiality and integrity protections offered by cryptographic protocols such as SSL/TLS can protect communications from malicious eavesdropping and tampering. Authenticity protections provide assurance that users are actually communicating with the systems as intended.

Where possible, use cryptographic techniques to authenticate information and keep the information private (but don't assume that simple encryption SUMMARY. This project will focus on research in cryptology at an advanced international level. Project topics will be analysis and construction of symmetric and asymmetric cryptographic algorithms and protocols. In particular we will use our knowledge involving deep techniques from coding theory on cryptological. What is a cryptographic protocol? A cryptographic protocol is a protocol executed by several distant agents through a network where the messages or part of the messages are produced using cryptographic functions (encryption, hashing, etc.). Cryptographic protocols are used for various purpose between the agents:. May 7, 2006 - This is regarded as offensive because of the malicious payload normally embedded in the virus, and because of the use of anti-anti-virus techniques For instance, on networks some layer 2 protocols are based on crypto (WEP, WPA/TKIP, and others), as are some upper layer protocols (IPSec, SSH, SSL, primitives such as commutative encryption. We give a list of some relevant al- gebraic properties of cryptographic operators, and for each of them, we provide examples of protocols or attacks using these properties. We also give an overview of the existing methods in formal approaches for analyzing cryptographic proto-. Using cryptographic techniques, it may be possible to allow intermediate results in a distributed algorithm to be certified independently of who provides them, reducing themes of complexity theory, e.g., interactive provability, average vs. worst-case complexity, and the inherent communication costs of multiparty protocols. Web is an electronic protocol which allows people to communicate mail, information, and commerce through a digital medium. This new method of information exchange has caused a tremendous need for information security. A thorough understanding of cryptography and encryption will help people develop better ways to etc. The analysis techniques discussed in this survey assume per- fect cryptography. This means that cryptographic primitives are considered as black boxes satisfying certain properties, as described in section 2.1. below. This assumption by it- self does not ensure security of the protocols.

Cybersecurity is a set of techniques to protect the secrecy, integrity, and availability of computer systems and data against threats. In today’s episode, we’re going to unpack these three goals and talk through some strategies we use like passwords, biometrics, and access privileges to keep our information as secure, but also as accessible as possible. From massive Denial of Service, or DDos attacks, to malware and brute force password cracking there are a lot of ways for hackers to gain access to your data, so we’ll also discuss some strategies like creating strong passwords, and using 2-factor authentication, to keep your information safe.

What is TRANSPORT LAYER SECURITY? What does TRANSPORT LAYER SECURITY mean? TRANSPORT LAYER SECURITY meaning - TRANSPORT LAYER SECURITY definition - TRANSPORT LAYER SECURITY 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 Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL), both frequently referred to as "SSL", are cryptographic protocols that provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing, email, Internet faxing, instant messaging, and voice-over-IP (VoIP). Websites use TLS to secure all communications between their servers and web browsers. The Transport Layer Security protocol aims primarily to provide privacy and data integrity between two communicating computer applications.:3 When secured by TLS, connections between a client (e.g., a web browser) and a server (e.g., wikipedia.org) have one or more of the following properties: The connection is private (or secure) because symmetric cryptography is used to encrypt the data transmitted. The keys for this symmetric encryption are generated uniquely for each connection and are based on a shared secret negotiated at the start of the session (see TLS handshake protocol). The server and client negotiate the details of which encryption algorithm and cryptographic keys to use before the first byte of data is transmitted (see Algorithm below). The negotiation of a shared secret is both secure (the negotiated secret is unavailable to eavesdroppers and cannot be obtained, even by an attacker who places themselves in the middle of the connection) and reliable (no attacker can modify the communications during the negotiation without being detected). The identity of the communicating parties can be authenticated using public-key cryptography. This authentication can be made optional, but is generally required for at least one of the parties (typically the server). The connection ensures integrity because each message transmitted includes a message integrity check using a message authentication code to prevent undetected loss or alteration of the data during transmission.:3 In addition to the properties above, careful configuration of TLS can provide additional privacy-related properties such as forward secrecy, ensuring that any future disclosure of encryption keys cannot be used to decrypt any TLS communications recorded in the past. TLS supports many different methods for exchanging keys, encrypting data, and authenticating message integrity (see Algorithm below). As a result, secure configuration of TLS involves many configurable parameters, and not all choices provide all of the privacy-related properties described in the list above (see authentication and key exchange table, cipher security table, and data integrity table). Attempts have been made to subvert aspects of the communications security that TLS seeks to provide and the protocol has been revised several times to address these security threats (see Security). Developers of web browsers have also revised their products to defend against potential security weaknesses after these were discovered (see TLS/SSL support history of web browsers.) The TLS protocol comprises two layers: the TLS record protocol and the TLS handshake protocol. TLS is a proposed Internet Engineering Task Force (IETF) standard, first defined in 1999 and updated in RFC 5246 (August 2008) and RFC 6176 (March 2011). It builds on the earlier SSL specifications (1994, 1995, 1996) developed by Netscape Communications for adding the HTTPS protocol to their Navigator web browser.

AAA framework: TACACS+ vs RADIUS
 
04:39
TACACS stands for Terminal Access Controller Access-Control System. Plus sign means a newer and updated version of TACACS. Like RADIUS, TACACS+ also uses AAA framework to provide centralized access into a network. RADIUS was designed to authenticate and log remote network users, while TACACS+ is used for administrator access to network devices like routers and switches. TACACS+ servers should be deployed in a fully trusted internal network. No direct access should be allowed from untrusted or semi-trusted networks.

○ Digital Signatures § Goal: verify Authenticity of a message. § Based on Asymmetric Cryptography. § Basic operations 1. Public / Private keys generation (using some algorithm like RSA) 2. Signing algorithm using the private key 3. Signature verification algorithm using the corresponding public key i. Extending previous Example • Steps (Order is very important, bold stuff is the difference added to authenticate sender) ® Party 1 (Alice) 1. Generates a random AES Session Key (32 bytes / 256 bits) 2. Generates a random Initialization Vector (IV) (16 bytes / 128 bits) 3. Encrypt the message to be sent using the AES Session Key & IV 4. Calculate an HMAC of the encrypted message using the AES Session key 5. Encrypt the AES Session Key using the Public Key of Party 2 (Bob) The recipient. 6. Calculate Signature using the private signing key on the HMAC 7. Sends a packet of (Encrypted Message, Encrypted Session Key, Initialization Vector, HMAC, and Signature) to Bob ® Party 2 (Bob) 1. Decrypts Session key using his Private Key 2. Recalculates the HMAC of the encrypted message (Validates message integrity) } If HMAC check pass – Verify digital signature using Alice Public Key w If signature verification pass w Decrypts the message using the decrypted AES Session Key and Initialization Vector w Otherwise, identity of the sender couldn't not be verified, reject message. } Otherwise, rejects the message because of integrity check failure. • Why Order matters? ® Timing Side-Channel Attacks ® Padding-Oracle Attack ○ Protocols § TLS/SSL • How TLS/SSL Works? • Mitigates against ® Man in the Middle Attacks ® Authentication, so the client can be sure it is talking to the correct destination. § Public Key Infrastructure (PKI) • Certificates aka X.509 Certificate (Sha-1 Signature Issues) ® A digitally signed file ® Identifies (Computer / User / Device) ® Has Public & Private Key, only the certificate owner has the Private Key. ® Has Expiration date ® Information about the CA that issued the cert ® X.509 Extension Attributes (like Usage attribute) ® Revocation Information. • Certificate Authority (CA) (CNNIC, WoSign) ® Issues, signs and manages certificates. ® Famous certificate authorities (Verisign, GoDaddy, … etc). • Trust Chains ® CA's can delegate the signing job to subordinate CA's ◊ Root CA's signs an intermediate signing certificate to the subordinate CA ® The subordinate CA can then issue certificates ® To validate a certificate, the client validates the signatures of all the intermediate stages and make sure all of them are linked to a Trusted CA • Certificate Revocation Lists (CRL's) ® When a certificate is compromised (Private Key leaked) it will be published on the CRL, so each time the cert is validated, the CRL list is checked in case cert is revoked. 3.

Public Key Infrastructure Fundamentals - Bart Preneel
 
01:31:53
The function of a public key infrastructure (PKI) is to ensure secure delivery and management of public keys. Alternative trust models lead to different key architectures. Public keys are published by means of digitally signed certificates. A private key may be compromised, in which case the certificate containing the corresponding public key must be revoked. Many revocation methods are in current use. Publication of Certificate Revocation Lists (CRLs) and checking with an Online Certificate Status Protocol (OCSP) responder are best established. Learning objectives + learn the components of a public key infrastructure. + understand key delivery and management mechanisms. A lecture by Bart Preneel at SecAppDev 2013 in Leuven, Belgium. Professor Bart Preneel of KU Leuven heads the COSIC (COmputer Security and Industrial Cryptography) research group. His main research area is information security with a focus on cryptographic algorithms and protocols as well as their applications to both computer and network security, and mobile communications. He teaches cryptology, network security and coding theory at the K.U.Leuven and was visiting professor at the Ruhr Universitaet Bochum (Germany), the T.U.Graz (Austria), the University of Bergen (Norway), and the Universiteit Gent (Belgium). In '93-'94 he was a research fellow at the University of California at Berkeley. He has taught intensive courses around the world. He undertakes industrial consulting (Mastercard International, S.W.I.F.T., Proton World International,...), and participates in the work of ISO/IEC JTC1/SC27/WG2. Professor Preneel is Vice President of the International Association for Cryptologic Research (IACR) and co-founder and chairman of LSEC vzw (Leuven Security Excellence Consortium).
