Establishing a secure communication channel is important—but how do you know you are communicating with the right entity? The structure of the internet makes it easy to launch so-called man in the middle attacks. This allows even secure communication channels to be established with the wrong site or computer. Alternatively, phishing attacks may try to confuse users by mimicking the look and feel of websites they are used to—like their bank’s site. On the web this problem is solved using so-called certificate authorities. A small number of trusted entities provide a basis on which the legitimacy of other sites can be established.

Is HTTPS really that difficult? Do I need to know crypto theory and a lot of math to understand it? You don't! This video explains how HTTPS works in very simple terms. It will touch upon encryption and digital signatures, as well as explaining what a trusted Certificate Authority is and what a self-signed certificate is. We will build upon this knowledge in upcoming videos, when we plan to issue a self-signed certificate to secure a microservice app in a testing environment. You no longer have an excuse to say HTTPS is too complex. Because this video simplifies all the concepts in less than 12 minutes.

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.

This video will look at how to install and setup Active Directory Certificate Services (AD CS) for use with Active Directory Federation Services (AD FS) on Windows Server 2012. Check out http://itfreetraining.com for more of our always free training videos. This video only performs a basic setup, if you are planning to use certificates in your organization you should perform additional research on certificates to ensure that the certificate hierarchy that you install meets the requirements of your organization. Download the PDF handout http://ITFreeTraining.com/handouts/federation/enterprise-ca-2012.pdf Demonstration role installation The server used is Windows Server 2012 Standard. The base install has been performed and the server added to the domain. 1) To install the Active Directory Federation Services role, open Server Manager from the quick launch bar and then select the option on the welcome screen “Add roles and features”. This will start the add/roles and features wizard. 2) For the first few screens the default will be selected. This will select the local server to install the role on. 3) On the “Select server roles” screen, tick the component “Active Directory Certificate Services”. When this is ticked, the wizard will also prompt for the feature “[Tools] Certification Authority Management Tools” to be added if it is not already installed. 4) On the “Select features” screen, no additional features are required so it is safe to press next and move on. 5) The next screen of the wizard is the Certificate Services welcome screen. Additional information about certificate services is displayed here. Once next is pressed, the next screen will be about configuration of the Certificate Services components. 6) On the “Select roles services” screen the administrator needs to decide which components of certificate services that they want to install. In this case the only component that is required is the default component “Certification Authority” so this can be left ticked and next can be pressed. 7) On the “Confirm installation Services” this will show the options that were chosen in the wizard, once the install button is pressed the install will start. It is just a matter of waiting until the role has been installed before it can be configured. Demonstration configuration the role Once the “Certification Authority” component of the Active Directory Federation Services role has been installed, it next needs to be configured. 1) To configure the role, open Server manager and select the exclamation mark next to the flag at the top of Server Manager. From the pull down menu, select the option “Configure Active Directory Certificate Services on the destination server” to start the configuration wizard. 2) The first screen of the wizard will ask which user that you want to use to perform the configuration. The user needs to be a member of the Enterprise Admin group and also have administrator rights on the local server. 3) The next screen asks which components of Active Directory Certificate Services that you want to configure. In this particular case, only the “Certification Authority” component was installed and is required to issue certificates. Once the “Certification Authority” component has been ticked the next button can be pressed to move on to the next screen of the wizard. 4) On the screen “Specify the setup type of the CA”, in this case the default option of “Enterprise CA” will be selected. An Enterprise CA works with Active Directory to issue certificates. In a later video the Standalone CA will be looked at when the install for HighCostTraining is performed. 5) The screen “Specify the type of CA”, the option “Root CA” will be selected. This performs an install that allows certificates to be installed that does not require other CA’s in order to operate. In order to have better security it is recommend to use the subordinate CA and have a secure Root CA in the company or use a 3rd party certificate authority. In order to keep the install simple in this video, the option for “Root CA” was selected and means that no other CA’s are required. 6) For the “Private Key”, “Cryptography”, “CA Name”, “Validity Period” and “Certificate Database” the default options were selected. If you are performing the install in a production environment, you should have a look at the options on these screens to determine if the options are right for you. 7) On the “Confirmation” screen this will show all the options that have been selected. Once the “Configure” button is pressed this will start the configuration of the role. Description to long for YouTube.

Windows Server Setup RADIUS and NPS For VPN Access Security When using networked services like VPN we want to be able to control access like we are able to control access to NTFS files/folders. Well by setting up RADIUS and Network Policy Server we are able to ensure that access to or corporate network is controlled a lot better. As an example we can filter based on groups IP addresses, time etc. The videos mention in this video refer to our VPN and CA Service: https://youtu.be/uMtJgN0prME and https://youtu.be/lWZIHoAwu2c For more visit: https://www.windows10.ninja https://www.servers2016.com Transcript (machine generated so it contains errors) Hello and welcome today's video today's video work and I show you how to set up a radius server with the NPS role on it like a network protection policies are okay. Am all we need to do is basically, you can install this if you have one box in your active directory server with that VPN role. Already there and then add this role to otherwise based on your security, setup, you can have is on a separate server and that's one option. Another option is have a on the remote dial in server like a VPN server. Okay, it just makes connections a little bit easier that way, but were having is on a separate server over here, which are method you choose literally what were doing 99.99% is Exodus add roles and features. Click next role next cayenne and were click clicking on network policy access and feature, click next play next next install okay. Once the insole is finished. Okay, the eldest up for tidiness okay, all you need to do is go network policy server that will open up this window and service 16, you have the's complete literally automatic configuration system where you must take note of it. But what we will do will ghost this way because a quick way and then will show you what you would have needed to have manually configure okay let's show us click on that, that's fine. Good direct configure the learn name. It's a VPN connection you can go without a domain name argument down. We are now creating a radius client okay. Given the friendly name VPN range the house okay the IP address is you might think. The client is talking about this computer. Now it actually asking for where there is a web service running or your VPN service, et cetera okay, we'll just type in the IP address as we know that we can also type in the full name. If we want to carry click verify resolve finds it all good. If we had set up a shared secret template that would be fine. Worse yet, secret template and were shared secret is is basically like shall we say a password on this computer and also on the other computer that is joining up to this radius server and that's it. We suggest you use the generate because you get he you thing you would want a copy this down because is no way you can rise up for this instance, what do is just quit a manual one in case it asks us to tighten the manual one hand that will be later. Okay, so it is create something simple that confer conforms to policies. Okay, okay, that's been added okay. We are gonna add in EAP that makes everything a lot easier a lot more secure and that's it. Microsoft protected earlier this, the last one more secure one configure if you want, how many connection attempts, that's fine. You can also add in the other ones. We suggest an mostly stick with that one than now one you would have needed to have done is basically on your active directory computer created a security group, and within that security group. You then add your users, and this is what the benefit of using this NPS radius system actually is. It's fairly similar to file and folder permissions, access permissions, we can limit those two certain groups, et cetera okay, you can filter based on certain criteria. In this, you can filter based on which group they're part of what IP address they are the connection method all those things, so we have already set one up on our active directory computer nine. That said, it finds it all good. Click next, you can create some IP filters if you do want to work on a girl with the highest encryption makes realm name is not really needed, but you can type it in. If you want to, and were literally finished before we go on to our VPN server with the setting and are quickly show you how that group needs to be set up okay.

In cryptography, a certificate authority or certification authority (CA) is an entity that issues digital certificates. The digital certificate certifies the ownership of a public key by the named subject of the certificate. This allows others (relying parties) to rely upon signatures or assertions made by the private key that corresponds to the public key that is certified. In this model of trust relationships, a CA is a trusted third party that is trusted by both the subject (owner) of the certificate and the party relying upon the certificate. CAs are characteristic of many public key infrastructure (PKI) schemes. This video is targeted to blind users.

PKI (Public Key Infrastructure) is a hierarchy of Certificate Authorities. This video looks at 3 different types of hierarchies that can be used to issue certificates. Download Handout http://itfreetraining.com/Handouts/Certificates/PKIHierarchy.pdf Considerations When deploying Certificate Authorities (CA's) you should consider the size of your company, geographic distribution and the number of certificates that are required. Before a certificate can be used it needs to be checked that it has not been revoked. This can be done via a CA or online responder. When deploying CA's consider WAN links the users may need to travel over when obtaining new certificates and also checking that an existing certificate is still valid. Single-Tier Hierarchy This means that there is one CA on the network. This is suited for small networks. Having one server does mean less administration; however, it does not provide any fault tolerance. In order to issue certificates, the server must be online. The CA contains private keys and when there is only one CA on the network the server cannot be taken offline in order to protect these keys. If an attacker was to obtain these private keys, they could effectively create their own certificates or decrypt any traffic encrypted with any existing certificate. Two-Tier Hierarchy This contains two levels of CA's. One Root CA and any number of child CA's. In order to improve security, the root CA is usually taken offline after the child CA's have been issued a certificate. The root CA only ever needs to be brought back online if another child CA is added to the network or a child CA needs to renew its certificate. Having a second level provides redundancy as multiple CA's can be created to issue certificates. Different CA's at the second level can be used for different reasons. For example, one CA may be for internal clients while another CA could be used for external customers or business partners. Three-Tier Hierarchy A three tier hierarchy adds another layer of CA's to the hierarchy. This improves security as the first 2 levels can be taken offline when not required. They can be brought back online only when new CA's need to be added to the network. Validity Period The validity period is how long a certificate is valid for before it cannot be used. The root CA certificate is the top of the hierarchy. Once the root CA certificate expires, all certificates in the hierarchy expire with it. For this reason, the root CA normally has a very high validly period like 20 years. A rule of thumb is that subordinate CA's have half the value of their parent CA. If they have the same validly period, this would mean that after the CA has been online for a day, it would be issuing certificates that expire after its parent CA.

Windows Server - Setup SSTP OR IKEV2 VPN ON Server Please see first: https://youtu.be/lWZIHoAwu2c This video follows on from our last video on how to setup a root CA with OCSP. In this video we show you how to use your self-signed ROOT CA and then your VPN certificate to setup a maximum encryption SSTP or IKEv2 Virtual Private Network (VPN) on Windows Server 2016. This should also work on earlier versions of Windows Server. For more visit: https://www.windows10.ninja https://www.servers2016.com Transcript (machine generated so it contains errors) In our last video we showed you how to set up our certificate authority with the OCSP service that basically checks to ensure that certificates issued by your CA certificate authority are still valid, et cetera, and that was a lengthy process that was there are so basically, if you're just run are some of your VPN with SSTP or IP version 2 et cetera and you just this video we suggest that you actually go to step one, which the previous video and in the description. We should have the link for the previous year okay. Please watch that follow that first set up your CA so that the OCSP and band. Now it's quite simple. Okay, so with all the previous having been done, what would you do is create a VPN. Okay, so as a virtual private network. Okay, where you are able to connect one PC or a lot of PCs to your server okay in a corporate environment under a secure encrypted system, so you could be working from home. For example, connecting into your works server during all the work that you need to do, and it's all done by an encrypted Internet connection using this VPN service. Now if I could quite simple to set up once you've got your previous certificate thing so that we need to do is will have ServerManager here that basically get one you get to just click on the server manager. But we also need to now create that VPN certificate, so I'll show you how MMC entering their and then we add okay certificate templates. We need that one okay certificates will be that one and make sure's computer account. Click next man finish, and then it certificate authority. We are that one in their local computer is fine, click finish. Click okay. Now we need to create that VPN certificate is cold that I can and we got certificate templates, double-click on that and it literally is this certificate with a little bit extra so rather than modifying this template letter a copy of it for a certificate template and will give it a name. Let's has that go general, let's call it VPN cert. I don't make sense inevitability period. You can change that. That's fine if you want added into active directory box, but for what we're doing right now it's all get compatibility. If you want the certificates to be readable, usable by older machines. You can have that you can have it all going for the latest version backwards compatibility gives you a greater number of machines that can connect simple as that. Okay general than request handling. We want to allow private keys to be exported. We have a cryptography that is fine as you see is that the CSP is basically all sorted arm key attestation, nothing to add in their issuance requirements. Okay, you could click over their CA certificate manager needs to approve the et cetera before it issued but which keep it as simple and straightforward as possible so server looking to add their subject name. This is actually because one of create search terms certificates with their all special names were actually gonna change the setting rather than active directory, generating all the data for us automatically, which may be only one, maybe not want were actually in our supply the data ourselves so supply in the request and cure… The then decided to place over their extensions. This is the most important, we are gonna add in here server authentication, which is very important server authentication. Okay, were also can add alliance authentication so add those two and were now we could make the extensions critical will. Click okay will clear a day on that and now we have a VPN cert template created our way. Now we need to just go into assessment show everything running the way we want okay in our certificate templates in the certificate authority, but make a you can see it's not here so we need to bring in let's click no certificate template

Pki 19.3 Module19 – Cryptography, Section 19.3 - Public Key Infrastructure (PKI) Public key infrastructure (PKI) is a set of roles, policies, and procedures needed to create, manage, distribute, use, store, and revoke digital certificates and manage public-key encryption. The purpose of a PKI: • Facilitate the secure electronic transfer of information for a range of network activities such as e-commerce etc. • Activities where validation is required by more than a passwords. PKI binds public keys with respective identities of entities. A PKI consists of: • A certificate authority (CA) that stores, issues and signs the digital certificates • A registration authority which verifies the identity of entities requesting their digital certificates to be stored at the CA • A central directory—i.e., a secure location in which to store and index keys • A third-party validation authority (VA) can provide this entity information on behalf of the CA. • A certificate management system managing things like the access to stored certificates or the delivery of the certificates to be issued. • A certificate policy stating the PKI's requirements concerning its procedures. Its purpose is to allow outsiders to analyze the PKI's trustworthiness. Certificate authority (CA) binds through a process of registration and issuance of certificates. • The PKI role that assures valid and correct registration is called a registration authority (RA). • An RA is responsible for accepting requests for digital certificates and authenticating the entity making the request. • An entity must be uniquely identifiable within each CA domain on the basis of information about that entity. PKI Design • Public key cryptography enables entities to securely communicate on an insecure public network, and reliably verify the identity of an entity via digital signatures. • A public key infrastructure (PKI) is a system for the creation, storage, and distribution of digital certificates which are used to verify that a particular public key belongs to a certain entity. • The PKI creates digital certificates map public keys to entities, securely stores these certificates in a central repository and revokes them if needed. Methods of certification Three approaches to getting this trust: Certificate authorities (CAs) Web of trust (WoT) Public key infrastructure (PKI) The primary role of the CA is to digitally sign and publish the public key bound to a given user. This is done using the CA's own private key, so that trust in the user key relies on one's trust in the validity of the CA's key. When the CA is a third party separate from the user and the system, then it is called the Registration Authority (RA), which may or may not be separate from the CA. The term trusted third party (TTP) may also be used for certificate authority (CA). CA is a trusted third party - trusted both by the subject (owner) of the certificate and by the party relying upon the certificate. Global TLS presence is competitive and dominated by 4 major CAs - Comodo, Symantec (acquired Verisign), GoDaddy and GlobalSign which account for 88% of the all issues TLS certificates of public facing web servers. Web of trust is a concept used in PGP, GnuPG, and other OpenPGP-compatible systems to establish the authenticity of the binding between a public key and its owner. Its decentralized trust model is an alternative to the centralized trust model of a public key infrastructure (PKI) There are many independent webs of trust, and any user can be a part of multiple webs. PKIs provide public keys, which are used for: Encryption and/or sender authentication of e-mail messages Encryption and/or authentication of documents Authentication of users to applications Bootstrapping secure communication protocols, such as IKE and SSL Mobile signatures Internet of things Open source implementations OpenSSL is the simplest form of CA and tool for PKI EJBCA is a full featured, Enterprise grade CA OpenCA is a full featured CA implementation using a number of different tools. OpenCA uses OpenSSL XCA is a graphical interface, and database. XCA uses OpenSSL IoT_pki is a simple PKI
