Create and validate TLSA records (DANE)
Hi,
I've talked about SSHFP in my last blog post and now, let’s talk about TLSA, another useful DNS record to put in a DNSSEC secured zone.
I will apply the example to HTTPS here but you can do this for everything that use TLS in fact (except for the web browser plugin part).
DANE and TLSA
Guetzli
Introduction
Guetzli is a JPEG encoder that aims for excellent compression density at high visual quality. Guetzli-generated images are typically 20-30% smaller than images of equivalent quality generated by libjpeg. Guetzli generates only sequential (nonprogressive) JPEGs due to faster decompression speeds they offer.
Add Brotli compression support to Apache for static assets and pages
The Apache web server doesn’t yet support stream compression using Brotli, but it’s easy to add support for static pages and assets such as CSS and Javascript files that you precompress. Browser support for Brotli is coming in Firefox 44 and in Chrome, and it provides about 15% savings versus precompressing with gzip/deflate.
First, download and build Brotli if it’s not already installed on your system. You’ll need to run make in the “dec”, “enc” and “tools” directories to build the bro executable. A quick note here, if you’re using an older version of GCC you might get an error message because your g++ doesn’t support the -std=c++11 flag. I ran into this on an older Debian server (GCC 4.6.3 from 2011), changed -std=c++11 to -std=c++0x in the CXXFLAGS line of shared.mk, and the build completed normally.
Compress and configure
Next, compress your files. If you already have static files compressed with the .gz extension, here’s a one-liner to recompress them all using bro:

Scan Linux for Vulnerable Packages
How do you know wether your Linux server (which has no desktop update notifier or unattended security updates running) does need to be updated? Of course an
apt-get update && apt-get --dry-run upgrade
might give an indication. But what of the package upgrades do stand for security risks and whose are only simple bugfixes you do not care about?
Check using APT
One useful possibility is apticron which will tell you which packages should be upgraded and why. It presents you the package ChangeLog to decided wether you want to upgrade a package or not. Similar but less details is cron-apt which also informs you of new package updates.

Open source auditing
https://cisofy.com/documentation/lynis/get-started/#installation-git
Lynis is an open source security auditing tool. Used by system administrators, security professionals, and auditors, to evaluate the security defenses of their Linux and UNIX-based systems. It runs on the host itself,
so it performs more extensive security scans than vulnerability scanners. It is also the client in our Lynis Enterprise offering.
Supported operating systems
Lynis runs on almost all UNIX-based systems and versions, including:
AIX
FreeBSD
HP-UX
Linux
macOS
NetBSD
OpenBSD
Solaris
and others ```UniqueMachine

Check DNS Resolution
Have you recently switched webhost or started a new website, then you are in right place!. DNS Checker provides free dns lookup service for checking domain name server records against a randomly selected list of DNS servers in different corners of the world. Do a quick look up for any domain name and check DNS data collected from all location for confirming that website is completely propagated or not worldwide.
DNS Propagation Checker
whatsmydns.net lets you instantly perform a DNS lookup to check a domain names current IP address and DNS record information against multiple name servers located in different parts of the world.
This allows you to check the current state of DNS propagation after having made changes to your domains records.
