The Internet Public Key Infrastructure (PKIX) is broken, but several solutions exist to fix some of the issues around transport encryption with TLS and x509 certificates.
This webinar will take a deeper look at two solutions: RFC 7672 “SMTP with DANE” and draft-ietf-uta-mta-sts “SMTP MTA Strict Transport Security (MTA-STS)”. What problems are solved with these solutions? What is needed to implement MTA-STS and SMTP-DANE? Is one solution preferable over the other, or should you deploy both?
SSL is an acronym for Secure Sockets Layer. It is a protocol used for authenticating and encrypting web traffic. For web traffic to be authenticated means that your browser is able to verify the identity of the remote server.
ARC is a new email protocol that captures and conveys authentication results when messages go through "indirect mailflows," like mailing lists, virus scanners, or alumni forwarding services. This allows the final recipient to see whether and how the message authenticated when it arrived at the first ARC-aware intermediary. Such information might be used by receivers to identify legitimate messages which, because of forwarding or alterations like subject tags or footers, no longer pass commonly accepted authentication checks. Today this can happen when an Internet domain publishes a strict DMARC policy, but email users with addresses in that domain send messages through these indirect mailflows.

Redistribution is necessary when routing protocols connect and must pass routes between the two.
Route Redistribution involves placing the routes learned from one routing domain, such as RIP, into
another routing domain, such as EIGRP.
While running a single routing protocol throughout your entire IP internetwork is desirable, multiprotocol routing is common for a number of reasons, such as company mergers, multiple departments
managed by multiple network administrators, and multi-vendor environments. Running different
routing protocols is often part of a network design.

standard for Web security.1 The first version
of SSL was never released because of
problems regarding protection of credit

Netscape created SSLv2, which made it
possible to keep credit card numbers
confidential and also authenticate the Web
server with the use of encryption and digital

Overview of the SSH protocol.
SSH (Secure SHell) is a secure replacement for TELNET, rcp, rlogin, rsh (for login, remote execution of
commands, file transfer).
Security-wise SSH provides confidentiality (nobody can read the message content), integrity (guarantee that data is unaltered in transit) and authentication (of client and server). This provides protection against many of the possible attack vectors like IP spoofing, DNS spoofing, Password interception and eavesdropping.
SSH exists in 2 versions. SSH-2 fixes some of the shortcomings of SSH-1 so it should be used in place of SSH-1.
SSH also comes with features that in itself raise security concerns like tunneling and port forwarding.

Let's Encrypt is a free, automated and open Certificate Authority to encourage the adoption of encrypted Internet connections. The inherent weakness of using third party CAs though, is they're able to issue certificates for any name or organisation. DANE is a protocol that allows certificates to be cryptographically bound to DNS names using DNSSEC, and this presentation also outlines how Let's Encrypt was tested with DANE records.
AWS IoT is a managed cloud platform that lets connected devices easily and securely interact with cloud applications and other devices. In this session, we will discuss how constrained devices can leverage AWS IoT to send data to the cloud and receive commands back to the device using the protocol of their choice. We will discuss how devices can connect securely using MQTT and HTTP protocols, and how developers and businesses can leverage the AWS IoT Rules Engine, Thing Shadows, and accelerate prototype development using AWS IoT Device SDKs. We will cover major hardware platforms from Arduino, Marvell, Dragonboard and MediaTek.
A presentation by Wes Hardaker from PARSONS given on 28 October 2014 at ION Santiago in Chile.
If you connect to a “secure” server using TLS/SSL (such as a web server, email server or xmpp server), how do you know you are using the correct certificate? With DNSSEC now being deployed, a new protocol has emerged called “DANE” (“DNS-Based Authentication of Named Entities“), which allows you to securely specify exactly which TLS/SSL certificate an application should use to connect to your site. DANE has great potential to make the Internet much more secure by marrying the strong integrity protection of DNSSEC with the confidentiality of SSL/TLS certificates. In this session, Wes will explain how DANE works and how you can use it to secure your websites, email, XMPP, VoIP, and other web services.
ION Bucharest, 12 October 2016 - DNSSEC helps prevent attackers from subverting and modifying DNS messages and sending users to wrong (and potentially malicious) sites. So what needs to be done for DNSSEC to be deployed on a large scale? We’ll discuss the business reasons for, and financial implications of, deploying DNSSEC, from staying ahead of the technological curve, to staying ahead of your competition, to keeping your customers satisfied and secure on the Internet. We’ll also examine some of the challenges operators have faced and the opportunities to address those challenges and move deployment forward.
ENSURING FAST AND SECURE GAMING APPLICATION DOWNLOADS GLOBALLYCDNetworks
Gamers are vocal about their displeasure when games are slow to download. Worse yet, if a game is unavailable due to too much traffic or a DDoS attack, gamers are, rightly so, incensed. And, if you have customers in China, Japan, Korea or Russia, performance can suffer due to distance induced latency. Find out how to protect your applications while ensuring fast downloads with dynamic web acceleration and DDoS mitigation. A dynamic content acceleration network not only ensures fast application downloads, but also accommodates peaks in traffic during a game launch. DDoS mitigation offloads attacks to special sponge PoPs, so your customers are not affected.
Takeaway
In this session you will learn how to speed up and secure your gaming application throughout the world, including in China, Japan, Korea and Russia. Your gamers will thank you.
Cisco Live 2019: New Best Practices for Hybrid and Multicloud Network StrategiesMen and Mice
Want to know what's bogging down your Hybrid and Multicloud strategies? Here we discuss some typical hurdles, shift in decision-making between DevOps and Network Managers and the importance of utilizing the service-native features available within the solutions that comprise your network, whether on-premise or cloud.
Part 3 - Local Name Resolution in Linux, FreeBSD and macOS/iOSMen and Mice
The focus of this webinar will be to take a deeper look into this local name-resolution system and the implementations for other Unix systems like Linux and FreeBSD. Linux’s new über-Daemon “systemd” supports both mDNS and the Windows LLMNR (Link-Local-Multicast-Name-Resolution). We will also show how well a Systemd-Linux behaves in heterogenous networks running both Windows and macOS.
How to send DNS over anything encryptedMen and Mice
Today, nearly all DNS queries are send unencrypted. This makes DNS vulnerable to eavesdropping by someone with access to the network. The DNS-Privacy group (DPRIVE) inside the Internet Engineering Task Force (IETF), as well as people outside the IETF, are working on new transport protocols to encrypt DNS traffic between DNS clients and resolver.
* DNS over TLS (RFC 7858)
* DNS over DTLS (RFC 8094)
* DNS over HTTP(S) (ID-draft)
* DNS over QUIC (ID-draft)
* DNS over DNSCrypt (outside IETF)
* DNS over TOR (outside IETF)
In this webinar, we will explain the protocols available or discussed inside and outside the IETF, and give some example configurations on how to use this new privacy protocols today.
The DNSSEC key signing key (or KSK) of the DNS root zone will be changed in the summer of 2017. During the time between July and October, all DNSSEC validating resolver need to get the new key material.
In this webinar we explain the KSK roll, how DNS resolver will load the new KSK with the RFC 5011 protocol and how a DNS administrator can verify that the new KSK is present in the resolvers configuration.
The CAA-Record for increased encryption securityMen and Mice
The CAA Record (Certification Authority Authorization) is used to signal which certification authority (CA) can issue an x509 certificate for a given domain. CAA creates a DNS mechanism that enables domain name owners to whitelist CAs that are allowed to issue certificates for their hostnames.
Starting from September 2017, certificate issuing CA must support the CAA record.
This explains the CAA record, how it works, how to enter CAA into a zone and how certification authorities are about to use the record.
This webinar is designed as an easy-to-follow tutorial on DNSSEC signing a zone for DNS admins. Our focus will be on DNSSEC zone signing automation with the Knot DNS Server and BIND 9.
Logging is important for troubleshooting a DNS service. Conveniently with BIND 9, almost all problems will show up somewhere in the log output, but only if the logging is enabled and configured correctly.
In this webinar, we’ll discuss the BIND 9 logging configuration and best practices in searching through large log-files to find the entries of interest. In addition, we’ll release log-management tools used by Men & Mice Services.
DNS High-Availability Tools - Open-Source Load Balancing SolutionsMen and Mice
The DNS protocol has built-in high availability for authoritative DNS servers (this will be better explained in the webinar!), but client machines can see a degraded DNS service if a DNS resolver (caching DNS server) is failing.
In this webinar, we will look into how the DNS clients in popular operating systems (Windows, Linux, macOS/iOS) choose the DNS resolver among a list of available servers, and how a DNS resolver service can be made failure-tolerant with open-source solutions such as “dnsdist” from PowerDNS and “relayd” from OpenBSD.
In this installment of the Men & Mice webinar series, Mr. Carsten Strotmann will talk about the role that DNS plays in fighting malware and spam.
The discussion will dig into DNS blacklists, domain reputation, Response Policy Zones and how the new TLDs have changed the game.
It goes without saying that DNS is only as secure as its servers. To ensure the successful and secure operation of a DNS server, secure configuration is paramount.
The new BIND 9 version 9.11 is a major version of the popular DNS server, released in August by ISC.
In this webinar Mr. Carsten Strotmann will demonstrate new features such as:
- Catalog Zones,
- dnssec-keymgr, new *rndc* functions
- CDS/CDNSKEY auto generation
- Negative Trust Anchor
- DNS cookies
-Refuse “any”
-and more.
Yeti-DNS is an international research project with the purpose of testing new technologies and procedures in running the Internet root zone. The project runs tests on DNSSEC key rollovers in the root, as well as experimenting with new ways to manage the DNSSEC keys (multiple zone signing keys).
An interview with Shane Kerr, a coordinator for the Yeti-DNS project, forms part of this webinar. The interview sheds light on the technical and political aspects of the project and introduces the latest results from experiments.
The webinar also includes a tutorial on how to use the Yeti-DNS root name servers to configure a BIND 9 DNS resolver in order to take part in the project.
A webinar that looks into the new features that the Windows Server 2016 will offer in the DNS, DHCP and IPv6 space.
Showcase of some of the new stuff using the latest tech preview and the aim is to give administrators a quick overview of the Windows Server 2016 and enough information to decide if early adoption is worthwhile.
Kea DHCP – the new open source DHCP server from ISCMen and Mice
This webinar will highlight the differences between the old ISC DHCP and new Kea DHCP (database support, dynamic reconfiguration, performance wins, scripting hooks) and will showcase the Men & Mice Suite as a graphical front-end to both ISC DHCP and Kea to ease the migration.
Keeping DNS server up-and-running with “runitMen and Mice
A traditional Unix/Linux init system like SystemV-Init or BSD rc does start a DNS server process on server boot, but it does not restart the service in case of an abnormal termination. Modern init replacements like systemd provide process supervision, but bring extra complexities and possible stability and security issues.
This webinar demonstrates an alternative, open source process supervision system called “runit”.
“runit” is lean and fast and sticks to the Unix tradition to do one thing, and do that right.
In this webinar you will learn how to manage DNS server processes such as BIND 9, Unbound and NSD from runit.
During the webinar, Mr. Carsten Strotmann from the Men & Mice Professional Services team will give an overview of the PowerDNS open source DNS server.
He will also give DNS operators information on how to:
- manage a DNS zone via SQL backend
- manage a DNS zone via BIND backend
- remote zone Backend
- DNSSEC signing with PowerDNS
- use the Men & Mice Suite controller for PowerDNS

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
