Securing public servers

Securing public servers help to prevent hackers from gaining access to additional hosts if a compromise were to occur. Learn about common attacks and mitigations.

  • Cloud service models Video — 00:08:27
    • 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.

  • Docker container lab Video — 00:04:08
    • 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.

  • Hypervisors and virtual machines Video — 00:08:24
    • Hypervisors are servers configured to host virtual machine guests. This episode will discuss Type 1 and Type 2 hypervisors as well as hardening.

  • Common attacks and mitigations Video — 00:09:47
    • 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.

  • Securing the cloud Video — 00:10:20
    • 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.

  • Ask me anything Video — 00:01:59
    • 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.

  • Cloud deployment models Video — 00:08:45
    • 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.

  • Exam question review Video — 00:02:10
    • 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.

  • Containers and software-defined networking Video — 00:11:27
    • 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).

  • Defining a public server Video — 00:00:44
    • 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.
