Configure Network Segmentation with TP-Link Omada Controller

In this tutorial, you will be shown how to configure network segmentation with the TP-Link Omada Controller. Segmentation is an ideal practice to protect your TP-Link Omada network.

What is network segmentation?

Network segmentation is, to put it as simply as possible, the practice of dividing a larger computer network into several small subnetworks that are each isolated from one another. Network segmentation is also a key part of HIPAA and PCI compliance. The benefits of segmenting your network can massively outweigh the challenges of configuration. Some key benefits of network segmentation include:

  • Slowing Down Attackers.
  • Increasing Overall Data Security.
  • Enabling Implementation of a Policy of Least Privilege.
  • Reducing Damage from Successful Attacks.

Vulnerabilities

Lost your iPhone? Someone can use Checkm8 and Checkra1n to jailbreak it.

If you lost your iPhone you should be worried. Someone can hack into it with free software called Checkm8 and Checkra1n to jailbreak it. Essentially they would be able to hack into your phone and by pass any security you have in place. 

Why should we care about Checkm8?

The Checkm8 vulnerability works on 11 generations of iPhones, from the 4S to the X. While it doesn’t work on newer devices, Checkm8 can jailbreak hundreds of millions of devices in use today. And because the bootrom can’t be updated after the device is manufactured, Checkm8 will be able to jailbreak in perpetuity.

  • Checkm8 requires physical access to the phone. It can’t be remotely executed, even if combined with other exploits
  • The exploit allows only tethered jailbreaks, meaning it lacks persistence. The exploit must be run each time an iDevice boots.
  • Checkm8 doesn’t bypass the protections offered by the Secure Enclave

Jetty Vulnerability using Invalid Large TLS Frame causes 100% CPU Usage

This Jetty vulnerability is to be considered as a service availability issue. When using SSL/TLS with Jetty, either with HTTP/1.1, HTTP/2, or WebSocket, the server may receive an invalid large (greater than 17408) TLS frame that is incorrectly handled, causing CPU resources to eventually reach 100% usage. 

The following packages have been upgraded to a later upstream version: rh-eclipse-jetty (9.4.40).

Security Fixes:

  • jetty: Symlink directory exposes webapp directory contents (CVE-2021-28163)
  • jetty: Ambiguous paths can access WEB-INF (CVE-2021-28164)
  • jetty: Resource exhaustion when receiving an invalid large TLS frame (CVE-2021-28165)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Install SSL Certificate Onto A FQDN UniFi Controller

In this tutorial you will be shown how to install SSL Certificate onto a FQDN (fully qualified domain name) UniFi Controller installed on Ubuntu 20.04. 

Lets Get Started 

  1. SSH onto your Ubuntu Linux Server
  2. Make sure your server is fully up to date with patches.
  3. Check and see what type of pre-existing firewall your using. In my case I am sticking with ufw firewall. We will be opening up the ports for SSL configuration and enabling auto start for my ufw firewall.
sudo ufw allow 80
sudo ufw allow 443
sudo systemctl enable ufw
sudo ufw enable

This Is A Must: Since you have an existing UniFi Controller already running make sure to set an A record for your domain and point it to the IP address of the UniFi Controller server. Lets move forward with configuring SSL certificate for your domain!
