Každopádně se jedná o soukromé stránky pro potřeby jedné rozvětvené rodiny. Ačkoliv věřím tomu, že by se řešení mohlo hodit i dalším rodinám, v tuto chvíli není v plánu žádné rozšiřování. Nicméně – pokud to všechno dobře dopadne, celý návrh řešení, všechny poznámky a informace k zabezpečení bych rád vyvěsil a dal volně k dispozici.

A new issue of my very irregular (not-so-much-about-security-now) newsletter is out! My original idea of publishing this every quarter (or so) was clearly too optimistic, as you can see. Which leads to a huge problem – there’s a load of links and texts I’d like to share with you, and the length of the text could be demotivating, I know. /docs/newsletters/2018-newsletter/ Thu, 01 Nov 2018 00:00:00 +0000 /docs/newsletters/2018-newsletter/ Long time, no see… It’s been a while since I shared any news from the outer world. Doesn’t necessarily mean I stopped reading or caring about the world or you, it just was a difficult year for me. But it’s time to restart this activity, hopefully with more feedback this time! :) Before we really start, I’d like to thank Shawn McGhee and Marek Kumpost for their suggestions, corrections and help with this. /docs/projects/secure-home-net/brainstorming/ Mon, 01 Jan 0001 00:00:00 +0000 /docs/projects/secure-home-net/brainstorming/ Secure Home Network Subnet Definitions Let’s start with some subnets definitions: VPN subnet For indidivual users B2B (or rather Home-2-Home) networks will use individual subnets.

We’ll demonstrate both the structure of the report and one of the possible analysis workflows you could use for your own research/work. Sample Preparation Before we start with the analysis, we need to download the memory image. That can be done via exercise 1 command issued on the VM command line (see the official course documentation for more details).
