Easy Web Firewall

skygear — Sat, 02 Jun 2012 23:13:40 PDT

Easy Web Firewall is a lightweight iptables-based firewall solution to mitigate problems resulting from hacked websites in shared virtual hosting servers. In such servers, vulnerable web applications are usually exploited by “hackers” to either:

Scan for additional vulnerabilities, both in the local server and remote ones.
Send spam mails through a cgi that avoids using the system mailer.

Since this actions do not directly prevent the server from operating normally, sysadmins do not usually notice that their server is infected until other servers start taking counter-measures against it. This is, their e-mails begin being rejected as comming from a spam source or their connections get blocked as vulnerability scanners.

Easy Web Firewall prevents these issues by easily allowing the system administrator to maintain a whitelist of allowed outgoing connections, using two different mechanisms:

First, EWF allows iptables blocking based on combinations of user, destination, and port. Hence, it blocks everything that is not whitelisted, promptly notifying the system administrator whenever this happens. Thereafter, sysadmins can quickly discover infected websites and take appropiate measures, or extend the whitelist if the connection attempt was legit. Additionally, since malicious connections are being blocked locally, the server’s reputation will remain intact. This is, it will not be suddently listed in any rbls or similar blacklists affecting the whole server’s user base.

Second, EWF also integrates with tinyproxy, to provide better detection of blocked remote websites. Because iptables is a low level firewall, it only knows about destination IP and port of the connections. However, when local websites try to open remote URLs, the administrator needs to know the actual URL to decide if that was a legit attempt, or one from a blocked website. Easy Web Firewall solves this issue by forcing local websites to make their HTTP(S) requests through a local tinyproxy installation. Thereafter, EWF combines the logs generated by iptables and tinyproxy to report both the local website that originated each blocked request, and its destination URL.

DNSCrypt v-0.9.4 – A tool for securing communications between a client and a DNS resolver.

skygear — Wed, 23 May 2012 02:49:46 PDT

DNSCurve improves the confidentiality and integrity of DNS requests using high-speed high-security elliptic-curve cryptography. Best of all, DNSCurve has very low overhead and adds virtually no latency to queries.

DNSCurve aims at securing the entire chain down to authoritative servers. However, it only works with authoritative servers that explicitly support the protocol. And unfortunately, DNSCurve hasn’t received much adoption yet.

The DNSCrypt protocol is very similar to DNSCurve, but focuses on securing communications between a client and its first-level resolver. While not providing end-to-end security, it protects the local network (which is often the weakest link in the chain) against man-in-the-middle attacks. It also provides some confidentiality to DNS queries.

The DNSCrypt daemon acts as a DNS proxy between a regular client, like a DNS cache or an operating system stub resolver, and a DNSCrypt-aware resolver, like OpenDNS.

Installation

The daemon is known to work on recent versions of OSX, OpenBSD, NetBSD, Dragonfly BSD, FreeBSD, Linux, Windows (MingW or Cygwin), and iOS (requires a jailbroken device).

Download the latest version and extract it:

$ bunzip2 -cd dnscrypt-proxy-*.tar.bz2 | tar xvf -

$ cd dnscrypt-proxy-*

Compile and install it using the standard procedure:

$ ./configure && make -j2

# make install

Replace -j2 with whatever number of CPU cores you want to use for the compilation process.

Running make -j2 test in the src/libnacl directory is also highly recommended.

On BSD systems, GNU Make should be installed prior to running the ./configure script.

The proxy will be installed as /usr/local/sbin/dnscrypt-proxy by default.

Command-line switches are documented in the dnscrypt-proxy(8) man page.

Usage

Having a dedicated system user, with no privileges and with an empty home directory, is highly recommended. For extra security, DNSCrypt will chroot() to this user’s home directory and drop root privileges for this user’s uid as soon as possible.

The easiest way to start the daemon is:

# dnscrypt-proxy –daemonize

The proxy will accept incoming requests on 127.0.0.1 and encrypt/decrypt them from/to OpenDNS resolvers.

Given such a setup, in order to actually start using DNSCrypt, you need to update your /etc/resolv.conf file and replace your current set of resolvers with:

nameserver 127.0.0.1

Other common command-line switches include:

–daemonize in order to run the server as a background process.

–local-address= in order to locally bind a different IP address than 127.0.0.1
–local-port= to change the local port to listen to.
–logfile= in order to write log data to a dedicated file. By default, logs are sent to stdout if the server is running in foreground, and to syslog if it is running in background.
–max-active-requests= to set the maximum number of active requests. The default value is 250.
–pid-file= in order to store the PID number to a file.
–user= in order to chroot()/drop privileges.

DNSCrypt comes pre-configured for OpenDNS, although the –resolver-address=, –provider-name= and –provider-key= can be specified in order to change the default settings.

Using DNSCrypt in combination with a DNS cache

The DNSCrypt proxy is not a DNS cache. This means that incoming queries will not be cached and every single query will require a round-trip to the upstream resolver.

For optimal performance, the recommended way of running DNSCrypt is to run it as a forwarder for a local DNS cache, like unbound.

Both can safely run on the same machine as long as they are listening to different IP addresses (preferred) or different ports.

If your DNS cache is unbound, all you need is to edit the unbound.conf file and add the following lines at the end of the server section:

do-not-query-localhost: no

forward-zone:

name: “.”

forward-addr: 127.0.0.1@40

The first line is not required if you are using different IP addresses instead of different ports.

Then start dnscrypt-proxy, telling it to use a specific port (40, in this example):

# dnscrypt-proxy –local-port=40 –daemonize

Queries using nonstandard ports / over TCP

Some routers and firewalls can block outgoing DNS queries or transparently redirect them to their own resolver. This especially happens on public Wifi hotspots, such as coffee shops.

As a workaround, the port number can be changed using the –resolver-port= option. For example, OpenDNS servers reply to queries sent to ports 53, 443 and 5353.

In addition, the DNSCrypt proxy can force outgoing queries to be sent over TCP. For example, TCP port 443, which is commonly used for communication over HTTPS, may not be filtered.

The –tcp-only command-line switch forces this behavior. When an incoming query is received, the daemon immediately replies with a “response truncated” message, forcing the client to retry over TCP. The daemon then encrypts and signs the query and forwards it over TCP to the resolver.

TCP is slower than UDP, and this workaround should never be used except when bypassing a filter is actually required. Moreover, multiple queries over a single TCP connections aren’t supported yet.
EDNS payload size

DNS packets sent over UDP have been historically limited to 512 bytes, which is usually fine for queries, but sometimes a bit short for replies.

Most modern authoritative servers, resolvers and stub resolvers support the Extension Mechanism for DNS (EDNS) that, among other things, allows a client to specify how large a reply over UDP can be.

Unfortunately, this feature is disabled by default on a lot of operating systems. It has to be explicitly enabled, for example by adding options edns0 to the /etc/resolv.conf file on most Unix-like operating systems.

dnscrypt-proxy can transparently rewrite outgoing packets before signing and encrypting them, in order to add the EDNS0 mechanism. By default, a conservative payload size of 1280 bytes is advertised.

This size can be made larger by starting the proxy with the –edns-payload-size= command-line switch. Values up to 4096 are usually safe.

A value below or equal to 512 will disable this mechanism, unless a client sends a packet with an OPT section providing a payload size.
GUIs for dnscrypt-proxy

If you need a simple graphical user interface in order to start/stop the proxy and change your DNS settings, check out the following projects:

DNSCrypt OSX Client: a preferences pane, a menu bar indicator and a service to change the DNS settings. OSX only, written in Objective C. 64-bit CPU required. Experimental.

DNSCrypt WinClient: Easily enable/disable DNSCrypt on multiple adapters. Windows only, written in .NET.

DNSCrypt Win Client: Official GUI for Windows, by OpenDNS.
