TLS in a hard way

How I've push it to the limits.
1. Use only most secure ciphers with forward secrecy.
SSLCipherSuite HIGH:MEDIUM:!SSLv3:!kRSA
SSLProxyCipherSuite HIGH:MEDIUM:!SSLv3:!kRSA

2. Enable SSL.
# diff httpd.conf httpd.conf.ORIGINAL
90c90
< LoadModule socache_shmcb_module modules/mod_socache_shmcb.so
---
> #LoadModule socache_shmcb_module modules/mod_socache_shmcb.so
148c148
< LoadModule ssl_module modules/mod_ssl.so
---
> #LoadModule ssl_module modules/mod_ssl.so
516c516
< Include conf/extra/httpd-ssl.conf
---
> #Include conf/extra/httpd-ssl.conf

3. Enable vhosts. Note that SSL is enabled before vhosts (as SSL config contains VHost, and default VHost is first)...
# diff httpd.conf httpd.conf.ORIGINAL
515,517c515,516
< # Secure (SSL/TLS) connections and Virtual hosts
< Include conf/extra/httpd-ssl.conf
< Include conf/extra/httpd-vhosts.conf
---
> # Secure (SSL/TLS) connections
> #Include conf/extra/httpd-ssl.conf

4. Restart HTTPD daemon: # systemctl restart httpd and ensure all works: # ss -tl

5. Ensure that only the very first vhost defined is httpd-vhosts.conf is HTTP host. All other must be HTTPS. It also perform HTTP redirect to corresponding HTTPS resource:
<VirtualHost *:80>
    DocumentRoot "/srv/http/html-static"
    ServerName web.prokop.net
    RewriteEngine On
    RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</VirtualHost>

6. Make redirect rule a bit more powerful, by adding just after RewriteEngine on conditions excluding HTTPS and Let's Encrypt (ACME) challenge:
    RewriteCond %{HTTPS} !=on
    RewriteCond %{REQUEST_URI} !^/\.well\-known/acme\-challenge

7. Add HSTS header to all SSL responses:
Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains; preload"

9. Ensure you got A+ from qualsys:

Hardening OpenWRT - adding non-root user account

I have at home an OpenWRT on TP-Link 1043ND. As I'm most of the time out of my home, I use this for two functions:  - as reliable WiFi Access Point  - as last resort remote access device  - as a box used to wake up other Ethernet enabled devices @ home. As this box is exposed to Internet via IPv6 address, I decided to harden it a little. 1. Adding extra non privileged user account: root@OpenWrt:~# opkg update root@OpenWrt:~# opkg install shadow-useradd root@OpenWrt:~# mkdir /home root@OpenWrt:~# useradd -D GROUP=100 HOME=/home INACTIVE=-1 EXPIRE= SHELL= SKEL=/etc/skel CREATE_MAIL_SPOOL=no root@OpenWrt:~# useradd -m -s /bin/ash bart root@OpenWrt:~# cat /etc/passwd root:x:0:0:root:/root:/bin/ash daemon:*:1:1:daemon:/var:/bin/false ftp:*:55:55:ftp:/home/ftp:/bin/false network:*:101:101:network:/var:/bin/false nobody:*:65534:65534:nobody:/var:/bin/false bart:x:1000:1000::/home/bart:/bin/ash root@OpenWrt:~# passwd bart Changing password for ...

Dropbear SSH keys and autossh on OpenWRT

Image
I have a box on Amazon EC2. And I want to have my OpenWRT that is behind IPv4 CGN and have public IPv6 to be reachable from IPv4 Internet. The best idea is to use ssh reverse tunnel connected with autossh to keep connection going. The very first think is to test if I can connect to my Amazon instance from my OpenWRT: root@OpenWrt:~# ssh 54.111.111.111 Host '54.111.111.111' is not in the trusted hosts file. (ssh-rsa fingerprint md5 0f:51:11:11:11:11:11:11:11:11:11:11:11:11:11:11) Do you want to continue connecting? (y/n) y root@54.111.111.111's password: At this point the public key of remote host will be added to .ssh/known_hosts. It is important as we can't have autossh to interact with console in future. root@OpenWrt:~# cat .ssh/known_hosts 2001:1111:1111:1111::1111:1111 ssh-rsa AAAAB3N....... 54.111.111.111 ssh-rsa AAAAB3N.......... Now we need to generate public/private key pair we will be using to connect to our Amazon instance. Invoke fol...

SSH Tunel with OpenWRT

You need to install OpenSSH client: root@OpenWrt:~# opkg update root@OpenWrt:~# opkg install openssh-client Now OpenSSH client replaced DropBear client: root@OpenWrt:~# ls -l /usr/bin/ssh -rwxr-xr-x    1 root     root        590667 May 24 14:54 /usr/bin/ssh root@OpenWrt:~# ls -l /rom/usr/bin/ssh lrwxrwxrwx    1 root     root            16 Aug 19  2016 /rom/usr/bin/ssh -> ../sbin/dropbear root@OpenWrt:~# ls -l /overlay/upper/usr/bin/ssh -rwxr-xr-x    1 root     root        590667 May 24 14:54 /overlay/upper/usr/bin/ssh Can you spot a difference: root@OpenWrt:~# ssh usage: ssh [-1246AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]            [-D [bind_address:]port] [-E log_file] [-e escape_char]            [-F configfile] [-I pkcs11] [-i identity_file...
