RFC 3514: New Bit Defined for IPv4 Headers
RFC 3514
was just released, with a new bit definition for use in the headers of IP packets. Because there are important security implications, anyone coding internet services (on either the client or server end) should probably take a look.
Finally, the scriptkiddie bit! Now we'll be able to drop all that pesky DDoS traffic with ease!

The bit set to 1 indicates a pr0n site, the bit set to 0 indicates a non-pr0n site.

Since the "evil" bit *MUST* be set in attack programs, I guess that will thwart all hacker attacks!! This RFC must have been sponsored by Micro$oft... After all, Microsoft makes hackers obsolete...

First post with the Evil flag set. If you are reading this comment, Slashdot is not RFC3514-compliant.
And not the last....
[In case you don't wanna bother or it's Slashdotted, it's about designating bits "evil" or not. Not that funny IMO, compared to some other good RFCs.]
Last 4/1 the editors posted about 15 of these in a row. Moderators got punchy and the whole place went to... well... be prepared.
I was reading the txt, thinking this is the stupidest thing ever, before i realized it was April Fool's.

This is a very elegant solution to most of the internets security problems. This could even prevent DDoS attacks! Does anyone know when the patched version of the SQL Slammer worm will be available, or should I just drop my firewall and let it install itself?

Please, please, please take this wonderful advance in technology and extend it to email. Then Spam can have a new header called "Evil: Yes". Then we can leverage the same technology to do perfect Spam filtering.

Unfortunately the RFC neglects to define what levels of evil the values of the 128-bit strength indicator maps to.
Therefore I, on behalf of the United Corp^H^H^H^H^H States government, submit that the top values should be reserved for the following:
2^127-n
4: Unpatriotic activity.
3: Terrorism. For up to date definition, see www.dhs.gov
2: Attempt to secure personal communication by encryption
1: Circumvention of copy protection mechanisms for purposes of piracy
0: Circumvention of copy protection mechanisms for purposes of "fair use"
Note that the last bit is reserved to indicate whether the packet originates from a foreign country.

An attacker can take advantage of the quantum nature of reality to set this bit to an indeterminate/combined value influenced by the nature of the observer of the packet. An observer who knows the evil nature of the sender of the packet will see the "evil" bit set to one, as it should be. However, unsuspecting observers, including firewalls and potential victims, will see the bit set to zero and be fooled.
The inherent subtlety of this attack is revealed by considering what happens when a security expert attempts to analyze the attack. As soon as he recognizes the evil nature of the attacker, the packets appear to have the 'evil' bit set, and his firewalls start dropping the packets, depriving him of further packets for analysis. The attack is thus even more precisely targeted towards the naive than an attack on Microsoft IIS.

Technically, you are wrong. It IS uscentric. Quoting directly from the FAQ...
Slashdot is U.S.-centric. We readily admit this, and really don't see it as a problem. Slashdot is run by Americans, after all, and the vast majority of our readership is in the U.S. We're certainly not opposed to doing more international stories, but we don't have any formal plans for making that happen. All we can really tell you is that if you're outside the U.S. and you have news, submit it, and if it looks interesting, we'll post it.
sooo, according the guys that own the place, it IS slashdot.org.us and if you are not in the US, well, your welcome to join too.
So it SHOULD have been posted later.

I won't comment on the legitimatcy of the article due to the date (4/1) but, this RFC seems to be technically perfect, but flawed in every other way.
Attacking systems MUST set the "evil" bit. Secure systems MUST drop the packets, insecure systems MAY chose their action -- drop, crash, give in.
Basically, this system, you give implicit trust to the remote system on the end of the communications, and let that system determine the security your own network will take in response to the communications.
Let one malicious user not flag his attack packets as evil, and the remote network will let him right in.
Sounds like a plan!
Course the thing is, they could come back here, post a reply thinking this was for real, then we'd all laugh at them, and they could just as easily turn around and say "Ha ha, had you going!" to get out of looking like a fool.

...and with karma to burn... who said life isn't perfect?
Some link layers, notably those based on optical switching, may bypass routers (and hence firewalls) entirely. Accordingly, some link-layer scheme MUST be used to denote evil. This may involve evil lambdas, evil polarizations, etc.
The great advantage of having a reputation for being stupid: People are less suspicious of you.
At least wait the hour and a half until April 1st.
and responding accordingly you can prevent access of evil packets.

--Sudhakar.
It seems to me that by setting the EVIL bit, a packet thereby becomes less evil, in fact not evil at all, and thus should set the bit to 0, but of course then it would be truly evil, and back at square one are we.
My head spins along with this bit. Can someone please clear this up? Is it a bit intended only for quantum computers?

I read it cover to cover (no, really) and thoroughly enjoyed it. It is a great book for those that are interested in network security; it has well told stories and good examples of best practices. I especially liked the way they described their logging machine: A server connected via a cat five wires that had seven of the eight pairs cut! The only pair left was the receive pair. Bad for TCP / good for UDP.

The Security Flag in the IPv4 Header
Status of this Memo
This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited.

Abstract
Firewalls, packet filters, intrusion detection systems, and the like often have difficulty distinguishing between packets that have malicious intent and those that are merely unusual. We define a security flag in the IPv4 header as a means of distinguishing the two cases.
1. Introduction
Firewalls CBR03 , packet filters, intrusion detection systems, and the like often have difficulty distinguishing between packets that have malicious intent and those that are merely unusual. The problem is that making such determinations is hard. To solve this problem, we define a security flag, known as the "evil" bit, in the IPv4 RFC791 header. Benign packets have this bit set to 0; those that are used for an attack will have the bit set to 1.
1.1. Terminology
The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, when they appear in this document, are to be interpreted as described in RFC2119
2. Syntax
The high-order bit of the IP fragment offset field is the only unused bit in the IP header. Accordingly, the selection of the bit position is not left to IANA.
The bit field is laid out as follows:
0
+-+
|E|
+-+
Currently-assigned values are defined as follows:
0x0 If the bit is set to 0, the packet has no evil intent. Hosts, network elements, etc., SHOULD assume that the packet is harmless, and SHOULD NOT take any defensive measures. (We note
that this part of the spec is already implemented by many common desktop operating systems.)
0x1 If the bit is set to 1, the packet has evil intent. Secure systems SHOULD try to defend themselves against such packets. Insecure systems MAY chose to crash, be penetrated, etc.
3. Setting the Evil Bit
There are a number of ways in which the evil bit may be set. Attack applications may use a suitable API to request that it be set. Systems that do not have other mechanisms MUST provide such an API; attack programs MUST use it.
Multi-level insecure operating systems may have special levels for attack programs; the evil bit MUST be set by default on packets emanating from programs running at such levels. However, the system MAY provide an API to allow it to be cleared for non-malicious activity by users who normally engage in attack behavior.
Fragments that by themselves are dangerous MUST have the evil bit set. If a packet with the evil bit set is fragmented by an intermediate router and the fragments themselves are not dangerous, the evil bit MUST be cleared in the fragments, and MUST be turned back on in the reassembled packet.
Intermediate systems are sometimes used to launder attack connections. Packets to such systems that are intended to be relayed to a target SHOULD have the evil bit set.
Some applications hand-craft their own packets. If these packets are part of an attack, the application MUST set the evil bit by itself.
In networks protected by firewalls, it is axiomatic that all attackers are on the outside of the firewall. Therefore, hosts inside the firewall MUST NOT set the evil bit on any packets.
Because NAT RFC3022 boxes modify packets, they SHOULD set the evil bit on such packets. "Transparent" http and email proxies SHOULD set the evil bit on their reply packets to the innocent client host.
Some hosts scan other hosts in a fashion that can alert intrusion detection systems. If the scanning is part of a be

There used to be a "security" bit you could use to mark you packets as especially interesting (the do-not-route-thru-Iraq-bit) [rfc 791]. Is that feature obsoleted by this evil?
If people don't protect their systems by checking this bit, and malicious packets ARE sent with this bit set, does this mean that they are partially responsible for any damage caused by the malicious packet? Are software vendors responsible for handling these packets properly? I can see the headlines now. Longhorn machine compromised by "evil" packets, Microsoft sued. From what I understand, even if MS is found 1% responsible and the attacker 99% responsible, MS would have to pay the majority of a large judgement since MS would almost certainly have more money than the attacker.
Actually, conceptually this could be used as a good thing. An "evil bit" that meant "drop this packet" could be used as a safety on network security testing. If I want to simulate an attack on machine A, I tell machine A to ignore the "evil bit" while machine B will continue to honor it. I don't have to worry about machine B doing anything based on my test packets, since it will drop them on the floor based on the "evil bit."
It could also be used to test firewalls for any possible damage done by malicious packets hitting the firewall and being dropped, in this case due to the "evil bit."
The router that implements this evil bit could send the packets to Write-Only-Memory.
"In 1972 Signetics recognized April Fools day by printing a full color datasheet for a Write-Only Memory. This is a chip which accepts data but never reads it back. Suggested uses include a data logger for bombs. Graphs show "number of pins left versus number of insertions" and other useful data. A couple of pins are dedicated to 6.3 volt AC input... for the filaments, of course! A scanned version is here (page 1) and here (page 2) (these are 150k .JPGs)."
It wasn't april 1st yet when you posted this. C'mon, if you are going to go with slashdot tradition, at least be a bit clueful. And yeah, I know it's not entirely the poster's fault, the RFC was released to soon too, but it just shows that, as usual, most /. posters can't spot a real april fools day joke if it ran up and smacked them right in the head.
Oh yeah, and, by by karma. Whatever.

Everything I've ever learned the hard way was based on a statistically invalid sample.
This is wierd. So now the hacker will set his evil bit to 1 because he is evil? and who will make sure he dont send it as 0. The only use I see of this is to distinguish to a server in a autonomous system that the packet originated internally or its an external packet. So the server can make distinction based on the bit to its behaviour. Is that what this bit is intended for??
