Third-party reconnaissance tools can provide extensive information about users, networks, and devices. In this video, you’ll learn about hping, Nmap, theHarvester, sn1per, scanless, and more. << Previous Video: Reconnaissance Tools – Part 1 Next: File Manipulation Tools >> In this video, we’ll look at some reconnaissance tools that may require you to install some additional […]

There are many reconnaissance tools that may be built-into your operating system. In this video, you’ll learn about traceroute, nslookup, ping, pathping, netstat, and more. << Previous Video: Certificate Concepts Next: Reconnaissance Tools – Part 2 >> The traceroute command allows you to map an entire path between two devices to know exactly what routers

Certificate management is an important part of a PKI. In this video, you’ll learn about offline CAs, OCSP stapling, certification pinning, trust relationships, certificate chaining, and more. << Previous Video: Certificate Formats Next: Reconnaissance Tools – Part 1 >> If you’re managing a certificate authority, one of the things you do not want to have

There are many different formats that can be used for certificate storage. In this video, you’ll learn about DER, PEM, PKCS #12, CER, and PKCS #7. << Previous Video: Certificates Next: Certificate Concepts >> The standard used when we are working with digital certificates is called the X.509 standard. It’s a standard format for these

We use digital certificates extensively for servers, users, and software. In this video, you’ll learn about using certificates for web servers, code signing, machines, email, and more. << Previous Video: Public Key Infrastructure Next: Certificate Formats >> In previous videos we talked a lot about what’s inside of a certificate but we haven’t talked about

It takes many different components to build a successful PKI. In this video, you’ll learn about the key management lifecycle, digital certificates, certificate authorities, and more. << Previous Video: Access Control Next: Certificates >> PKI or Public Key Infrastructure, is the process of managing practically every aspect of digital certificates. This covers the policies and

Access control is a fundamental aspect of IT security. In this video, you’ll learn about mandatory, discretionary, role-based, attribute-based, and rule-based access control. << Previous Video: Federated Identities Next: Public Key Infrastructure >> Once a user gains access to a service, we now need to determine what type of resources does that user have access

Instead of maintaining your own authentication database, you might use one from a third-party. In this video, you’ll learn about federation, SAML, OpenID Connect, and OAuth. << Previous Video: Identity and Access Services Next: Access Control >> Federation is a way that you could provide access to your network using credentials that someone uses for

As a security professional, you’ll need to use different authentication methods in different situations. In this video, you’ll learn about authentication using RADIUS, TACACS, Kerberos, and 802.1X. << Previous Video: PAP and CHAP Next: Federated Identities >> One of the more common authentication authorization and accounting protocols is the RADIUS protocol. RADIUS is the Remote

Authentication protocols have been used for many years in IT security. In this video, you’ll learn about the authentication process and the differences between PAP and CHAP authentication. << Previous Video: Authentication Management Next: Identity and Access Services >> There are many different ways to provide authentication to a network. And in this video, we’ll
