<h3>Technical Details</h3><h4>Impact</h4>

<p>On December 17, 2019, Citrix reported vulnerability CVE-2019-19781. A remote, unauthenticated attacker could exploit this vulnerability to perform arbitrary code execution. This vulnerability has been detected in exploits in the wild.</p>

<p>The vulnerability affects the following appliances:</p>

<ul>

<li>Citrix SD-WAN WANOP firmware and appliance models 4000, 4100, 5000, and 5100 – all supported builds. (Citrix SD-WAN WANOP is vulnerable because it packages Citrix ADC as a load balancer).</li>
</ul>

<h4>Detection Measures</h4>

<p>CISA has released a utility that enables users and administrators to detect whether their Citrix ADC and Citrix Gateway firmware is susceptible to CVE-2019-19781.<a href=”https://www.us-cert.gov/ncas/current-activity/2020/01/13/cisa-releases-test-citrix-adc-and-gateway-vulnerability”>[10] </a>CISA encourages administrators to visit CISA’s <a href=”https://github.com/cisagov/check-cve-2019-19781″>GitHub page</a> to download and run the tool.</p>

<p>Administrators should review NSA’s <a href=”https://media.defense.gov/2020/Jan/10/2002233132/-1/-1/0/CSA%20FOR%20CITRIXADCANDCITRIXGATEWAY_20200109.PDF”>Citrix Advisory</a> for other mitigations, such as applying the following defense-in-depth strategy:</p>

<p>“Consider deploying a VPN capability using standardized protocols, preferably ones listed on the National Information Assurance Partnership (NIAP) Product Compliant List (PCL), in front of publicly accessible Citrix ADC and Citrix Gateway appliances to require user authentication for the VPN before being able to reach these appliances. Use of a proprietary SSLVPN/TLSVPN is discouraged.”</p>

Follow on from VMware Starting Certifications – 2020 designations now in place

This post was originally published on this site
Last year I wrote a brief introduction into the VMware starter and professional certifications.

VMware have now upgraded the certification titles with the new 2020 designations.

If you’re new to the certification trail, any exams you now sit will lead towards the new certification, VMware are currently working on their upgrade paths, and I’ll post information as I find it.

If you are a VCP-x2019 VMware have said that their system has logic to realise you’re a VCP-x and that the 2019 designation will lead to VCAP-x2020s

The new certification designations 2020 for the starter courses and the VCP are as follows.

The VMware Certified Associate


This certificate is aimed at providing a good overall knowledge of the VMware products and why they are used.

The VMware Certified Professional tracks are as follows.

Data Centre Virtualisation (DCV Track)

 This track focuses on the birth of VMware and their VM hypervisor product.
  
Network Virtualisation (NV) Track

This track focuses on the VMware NSX products, and now prioritises the VMware NSX-T product.
Cloud Management and Automation (CMA) Track
This track focuses on the vRealize suite of products, these products can be used in a truly multi-cloud environment
Desktop and Mobility (DTM) Track

This track focuses on VMware Horizon, which in its simplest form provides a Virtual Desktop Infrastructure
  
Digital Workspace (DW) Track

This track focuses on the VMware WorkspaceONE and Digital workspace solutions, this provides and extensive set of endpoint management technologies.

VMUG Advantage

Today I decided to buy the VMUG Advantage Membership. The membership is around for a while now but for some reason; I never cared to take a good look at it. It provides some great resources and discounts, and since I plan to go to VMworld, get some certifications and play around in the homelab this year, I thought: why not… VM…

Why Do We Sign? To guarantee the security of your download, VMware releases are cryptographically signed. The certificate used to sign legacy releases of software expires at the end of December 2019.

HCX Service Mesh Considerations #HCX @VMwareHCX #vExpert

This post was originally published on this site

So let us have a quick overview of HCX Service Meshes before we continue: Service Meshes can contain all 3 appliances or just an Interconnect appliance or just a Layer 2 Ext appliance, depending on your needs. The WAN Optimiser is optional. Features are always being added to HCX, but these are the key services/appliances. The Interconnect (IX) appliance holds most of the services, I tell people to think of it as a vSphere Replication Manager, as that is one of the main services it holds. HCX uses vSphere Replication for all its replication bits, so the same pros and cons that apply to vSphere Replication apply here as well! How the Mesh is configured and deployed is dependant on […]

VCDX-NV – Document Submission

This post was originally published on this site

To start my blogging career, I thought I would talk about my VCDX-NV journey. I’m currently in the waiting stage after submitting my documents.  Waiting for a VCDX panel to determine if my documentation warrants an invite to defend. Whilst waiting, I thought I’d take this time to share some advice that I found useful on my journey.  Firstly, read and understand the blueprint this can’t be stressed enough.  During your journey; you will find all VCDXs repeat this phrase to you, and it’s true.  The closer you get to the submission date the more the blueprint resonates. Read the submission document.  I read this at the very end, but I wish I had read it a few months before.  […]
