Virtual machines, often referred to as instances, are widely used both on-premises and in the cloud. This episode tackles issues related to being aware of deployed instances in the interest of reducing the attack surface.

Containerized applications are self-contained boundaries consisting of only application files, not an operating system. This demo shows how to work with Docker containers on the Linux platform.

Public servers can be hosted as virtual machines in the public cloud. In this episode, a scenario is presented where a virtual machine requires access to specific cloud-based resources.
Securing the cloud

Video - 00:10:00

Cloud security is generally split between the Cloud Service Provider (CSP) and the cloud tenant, depending on which type of cloud service is being used. Security solutions include firewalls, data loss prevention tools as well as a Cloud Access Security Broker which enforces cloud computing security policies.
Cloud service models

Video - 00:08:00

Cloud computing services are categorized using the term “as a service” (aaS). This episode discusses IaaS, Paas, SaaS, and where responsibility lies for each type of service.
Cloud deployment models

Video - 00:09:00

Virtualization alone does not constitute cloud computing; a number of characteristics such as resource pooling and metered usage must also be involved. This episode discusses public, private, hybrid and community clouds.
Hypervisors and virtual machines

Video - 00:08:00

Hypervisors are servers configured to host virtual machine guests. This episode will discuss Type 1 and Type 2 hypervisors as well as hardening.
Containers and software-defined networking

Video - 00:11:00

Modern software development often uses application containers which serve as a logical boundary for app files and settings outside of the operating system. This episode also covers software-defined networking (SDN).
Common attacks and mitigations

Video - 00:10:00

Public servers are subjected to many types of attacks that can be mitigated by hardening the network and host using a wide variety of methods. This episode covers common attacks include DDoS, URL hijacking/redirection, session replay, and pass-the-hash.
Defining a public server

Video - 00:01:00

Public servers offer services to Internet users. These servers should be hardened and placed on an isolated network such as a screened subnet or DMZ so that in the case of compromise, lateral movement by the attacker will not allow access to other sensitive hosts.
