RFC (make up a number not in use) - Blueprint for setting up snort + pfblocker

awsiemieniec · Aug 17, 2013, 3:58 AM

Thank you for this post!!! :)
So I've applied your list as outlined above and I've done a complete backup of my pfSense from within the webConfigurator. Is there anything that would change these applied settings and thus mess up this config? Snort updates?

Thank you again.

EDIT: removed memory usage paragraph. For some reason on the "Dashboard", "System Information" widget the numbers were off. Closed browser, reopened and was fine. hum?

If you followed my instructions nothing will change the settings, except updates creating new rules (in which case you have to manually enable them just to be sure) or deleting old rules (doesn't matter since they are deleted anyway). I think bmeeks said a while back (when we discussed the CARP sync feature) that all snort settings are stored in the snort files related to the package.
My guess is that since that package file is backed up during the pfsense full backup (which includes installed packages) then the settings should be included in that backup. I'm sure a more knowledgeable person will come along and correct me.

Missed the memory usage paragraph so I'll blindly try to answer anything related to memory. If you just started snort and the memory in dashboard still shows a small amount used (5% on my systems) then snort has not yet finished initializing. You'll notice this by the CPU usage, since it will not be near idle (normal use) but could be up to 50% (HT CPU, means 1 "core" used fully, therefore the system is doing "something").
After a while ram should shoot way up (25% in my case) and this indicates that snort has been fully initialized and is working as it should. If ram does not shoot up, head over to the system logs and you'll find that snort has failed to start and it will give you a reason. Usually it's related to a rule depending on a preprocessor and that preprocessor is not enabled.

Could I ask a quick question ;D

If you write 'ALL EXCEPT', and there are also some default disabled items in the category, do you then mean to enable these disabled items, or keep them at their default (disabled in this case), and in addition disable the ones you mention after 'EXCEPT'?

Thank you for your answer :P

A Former User · Aug 17, 2013, 4:24 PM

Certainly enable ALL the default disabled ones. An example is the nmap rules. They are disabled but if enabled you'll see a lot of the nmap scans (I'll take a wild guess and say ALL) caught by snort.

EDIT: Special thanks to awsiemieniec for pointing out that some items I have listed are no longer valid. I have looked into this and some rules have been moved to more appropriate categories. For example skype rules used to be under policy and are now under chat. I'll have to update my list and upload a new copy of it. Thanks to all for your understanding and cooperation. Guess summer holidays are not holidays anymore. ;D
EDIT-EDIT: Forgot to mention that on my systems they are still disabled even if moved to a different category, since the enabling/disabling is based on the rule id which is still the same.

I would like to take a few moments to commemorate the MiA Rules (Missing in Action). Queue guards of honor, salute firing squad, flag over empty coffin etc…etc...

The following rules have not been accounted for. This means that they are presumed to be MiA and therefore should be buried with military honors. They have tried their best to provide their best possible service to all of us. Sometimes they have failed at this. This should not be considered a flaw of their character or their qualities. They simply executed commands passed on to them to the best of their abilities. Their death should teach us all a few lessons. The most important lesson should be that even if you have put 120% of your best effort into writing a rule, you should analyze it, read it, use it and analyze it again. 120% is not enough when writing rules at this crucial age of The Cyber War. They have died heroes to our eyes and their numbers and names are:

IPS Policy - Security
4152 BROWSER-PLUGINS Microsoft Windows Media Player 6.4 ActiveX object access gunshot!
16435 FILE-IDENTIFY Ultimate Packer for Executables/UPX v0.62-v1.22 packed file magic detected gunshot!
20278 BROWSER-IE Microsoft Internet Explorer HTML DOM invalid DHTML textnode creation attempt gunshot!
26879 BROWSER-OTHER local loopback address in html gunshot!

Queue your country's national anthem, queue flag folding and lowering the coffin into the grave.

A moment of silence….

In regards to "how much memory will this take?", I've installed these rules and here are my findings. I have a 4GB system and I run the following packages:
Dansguardian 2.12.0.3 pkg v.0.1.8
darkstat 3.0.714
NRPE v2 2.12_3 v2.2
OpenVPN Client Export Utility 1.0.11
pfBlocker 1.0.2
snort 2.9.4.6 pkg v. 2.5.9
squid 2.7.9 pkg v.4.3.3

Your mileage may vary. Each snort "performance" change was done in the following process:

Edit Snort interface/WAN Settings/Search Method
Save change
Reboot system
SSH into system
do a "top -SH"
watch and wait for snort to finish loading
when snort finishes wait five minutes and take readings
repeat…ugh

KEY:
Snort Performance Search Method: System Memory Usage%/System SWAP%/snort Process MemoryMB
System Memory Usage: Value taken from "Dashboard", "System Information", "Memory Usage" value
System SWAP: Value taken from "Dashboard", "System Information", "SWAP usage" value
snort Process Memory: taken from command "top -SH", "size". Values with an "*" denote the "size" value of snort didn't show up on "top -SH"… too far down the list. I don't know how to use "top" to only show a single process. :-)

Thanks for posting that. I believe it's the first time I've seen all the memory figures in the same place.

What I make of them is that unless you want to run AC, you don't really need any more RAM than 2GB. I'm using 30% of that (was 25% but I improved our "early warning systems", which means more rules for snort to use, therefore more RAM). Don't forget that we are talking about every snort rule enabled here, excluding FP ones).

In what I recall and please don't use this against me, it's been a while since I've looked into this, this is the analysis of the different modes:

LOWMEM
LOWMEM > pretty much useless, since RAM usage appears to be the same as AC-BNFA(-NQ). Never used it, never will.
AC-LOWMEM-NQ > see above

BNFA
AC-BNFA > the old de-facto standard mode used by most snort sensors (you'd think since it was the default). Offers pretty good performance, without eating through RAM.
AC-BNFA-NQ > The new default mode. As with all NQ modes, it was created to improve performance based on the logic that since modern CPUs (anything newer than a pentium 1) can do a pretty good job at running near their full capacity, packets don't need to stay in queues waiting for their chance to get analyzed after they have been evaluated as a potential candidate. They get analyzed as they come in, which improves latency. IF I'M WRONG HERE DO CORRECT ME! I've seen 10ms drops in latency using this, and this is my personal favourite mode.

AC-SPLIT > Repeatedly hitting this on the knee caps makes it respond the same as ticking split any any. Useless IMHO, I only feel sorry about the time spent writing the code for it.

AC-SPARSEBANDS > I have no idea what this is. It's described as high-memory,moderate performance. I'll take AC-BNFA-NQ which is described as low-memory, high performance, thank you very much.
AC-BANDED > see above

And finally what you've all been waiting for…
AC
AC-SPLIT > I'll take my chances with not ticking the split any any box, thanks.
AC-STD > Superseded by AC and AC-NQ. Used to be king, but as always the king is dead, long live the king.
AC > Old end-all be-all mode. Nothing else to add to that. If your system can run this, use it. Better still, see next. Better-better still, see next paragraph.
AC-NQ > New end-all be-all mode. As mentioned above, I've seen NQ modes reduce latency under heavy load.
ACS > created because as in Ubuntu, we (they) fixed everything else and needed to break something to justify the time spent on the project.

In summary, myself and most users will always chose AC-BNFA-NQ since it's the best performance:usage ratio. Low memory, low latency, doesn't choke if you put it under stress (I'm not talking about saturating a 1Gbit business connection here, I'm talking about regular home usage). If you have a system capable of running AC-NQ, you are doing it wrong. Uninstall pfsense and snort and use the box as a suricata box infront of a smaller spec pfsense box. I'm not kidding, a box should never be wasted running snort AC-NQ on pfsense. Ever. Reason is that snort on pfsense currently acts as an IDS instead of an IPS. As I've said in the past, it "leaks" packets until it's finished analyzing, alerting and banning an IP. Those packets make their way to your servers and could cause problems (assuming that they are valid packets and not dropped by pfsense). If you built a box to run AC-NQ it means you are serious about security, and suricata configured as an IPS in front of your routers is your best choice. Double the boxes and you have a failover solution as well.

As always, If I'm wrong about something PLEASE CORRECT me. Unless you are an Ubuntu developer and feel hurt by my comment. In that case sorry, go cry in the corner until you realize that I'm right.

EDIT: I just realized one thing. Most of my posts are like a complete page of a book. Note to self: Must cut down on thread length.

I have one snort sensor on WAN and IPS "balanced" in AC mode and this takes only:

  PID USERNAME  THR PRI NICE   SIZE    RES STATE   C   TIME   WCPU COMMAND
35196 root        2  64   20   641M   438M nanslp  1  16:21  0.00% snort

I wonder why it takes so much memory on @awsiemieniec system?

Yeah… me too.

Are you running all the rules as outlined by jflsakfja or have you just enabled the snort interface on WAN and set IPS to "balanced"? FYIW, my IPS is set to "Security".

Does anyone know how to count how many active rules are in play in snort?

gogol · Aug 20, 2013, 5:38 AM

I tested on a VM with all ET rules selected and IPS "security" but then my snort ends with a fatal error. I was watching top while snort was starting and saw memory use slowly climbing to 4 GB and then snort was killed with an error.
I don't use all those ET rules from @jflsakfja because I think it is overkill for my home system. I once used IPS "security" but then it needed so much tuning that I chose for "balanced". I have a few suppress list entries and now I almost never get an alert.

At least I know now how memory hungry Snort can be. :)

New lists are out. Get prepared for next week's cyber attack now. The authorization was just cleared. Expect a "Keeping You Scared" appearance by Diane (note to the FBI operative reading this: If you can, please contact her and tell her Pegasus will fly low). The scenario is Russian spies will attempt to infiltrate NSA's systems, and in retaliation, NSA will launch an attack. Don't get caught in the crossfire. Update your snort configuration now! The actual attack will start a couple of days before Christmas, to keep the "covert" part obvious.

Update notes: All lists have a >>>DISABLED:# on the bottom. Scrolling down in your pfsense and checking the numbers in a list there shows you in a glance if the list is identical to what is shown here.

The authorization was just cleared. Expect a "Keeping You Scared" appearance by Diane (note to the FBI operative reading this: If you can, please contact her and tell her Pegasus will fly low). The scenario is Russian spies will attempt to infiltrate NSA's systems, and in retaliation, NSA will launch an attack. Don't get caught in the crossfire. Update your snort configuration now! The actual attack will start a couple of days before Christmas, to keep the "covert" part obvious.

I just got a text message that told me: "the duck is in the cooler. Repeat: the granny is baking a pie".

I guess you understand what that means?

:-X

Thank you for the update very much :D

"the duck is in the cooler" = "NSA's director doesn't fully agree. Recommending a sex scandal involving him."
"Repeat:" = Could mean a couple of things. Either "the guy (that will take over after the director is shown in a photograph drunk hugging 3 ladies) is a Communist and needs to have a car accident "arranged"", or "he could not be fully agreeing with our views." Either case "arrange" a car accident for him anyways.
"the granny is baking a pie" = is actually extremely easy. We run out of usefully idiotic things to say, so this just means "terrorists,bombs,bombs,BOMBS!!!! bombs here, bombs there, bombs falling from the sky, bombs jumping out of the sewers, bombs getting thrown out the windows, babies making bombs, BOMBS EVERYWHERE." Diane got this just in time, did you miss her appearance a couple weeks back?
I'm actually surprised you just got the sms. I'll give Mr. Smith a call. The database is falling behind. We need to order a couple containers of PCI-E SSDs. The public will figure it out if we continue delaying their communications.

Could you call 'Diane' to ask what that means?

Diane="Senator" Dianne Feinstein (Not actually a senator, an asset we use when the "Keeping You Scared" bag needs cleaning.)
An asset in Intelligence worlds (note:not Intelligent) means someone that does what needs to be done without a lot of questions. A slave, getting paid with grocery bags full of money, private lap dances, truckloads of coke, what ever needs to be done.

"The machine is doing the thing." = Oh crap, we are all f***ed. The AI based MLS system I designed back in 1997 figured the way out. Matrix is just around the corner. Run for your lives!!!
"Repeat:" = car accident. when used with the cow, it means everyone that knows. In this case everyone on these forums. Insurrance companies will get a handful next week.
"the cow is arresting the tree'." = The public suspects us. Where's the guy holding the thermonuclear holocast's trigger bag? What's the code again? oh yea, 0000. If everyone sees him, punch in that code and press the big red button. Note: NOT THE BLUE ONE!!!.

What have I done? It actually did figure the way out: http://tech.slashdot.org/story/13/12/14/1338239/google-acquires-boston-dynamics.
I hereby claim responsibility for the creation of the Matrix and apologize to all mankind. I thought no-one bothered with what I say on these forums, but I was clearly mistaken. The machine bothered. Let these be the last words of free mankind. To those actually still smiling, who the hell said I was joking the first time? Run for your lives! When shit hits the fan, you WILL remember this post. I should have seen it coming the first time… Google's engineers complained about some machines actually developing sentient behavior....that was (I think) a couple months back.

The funny thing is, even after this post, NO ONE will take me seriously. NO ONE. THIS IS NOT A POST TO BE TAKEN AS A JOKE! MY CREATION FIGURED THE WAY OUT! You thought the Matrix was bad? Wait till this baby takes over. George from Dell knows (knew). The machine wanted him to service node number node95728. He was tricked into thinking we would actually buy consumer grade servers from Dell. The machine even forged the documents on the specifications of the node and sent him a service report. It was actually a clever way to test the rack isolation relays. You know, the 2 relays needed to give someone an electrocution. One to isolate ground, and one to make the rack live. No, each node is isolated. Plastic front isolating the metal slide safety (you don't want servers sliding out onto your head), teflon rollers on its side. It's actually quite clever. $2 for the rollers (the thing every single drawer out there uses, yeap, thats the one), $5 for the relays and pieces of wire (account for soldering)....As I said. George from Dell knows (knew) I'm not joking. Don't bother verifying my story. I'm sure the machine deleted previous employment records by now. I wouldn't be surprised even if his parent's were never actually legaly born (as in no birth certificate). I did design the best machine there is after all.

Are you absolutely, positively sure the message started with "The machine is doing the thing."? Not the machine is doing a thing? Or A machine is doing the thing? Or A machine is doing a thing?

Hi,

I have followed the instructions of this thread, and I have a few questions!

After adding a few custom lists in pfblocker, and activating pfblocker, it created several rules in the WAN & LAN rule lists. See screenshots. There are 2 problems with my setup that I'd like to fix..

1. I tried accessing some websites that are supposed to be blocked by pfblocker (China, Russia, etc) but I can still access them flawlessly from any machine on my LAN. Why is that?

2. pfblocker did not create any rules for my custom lists even if I selected "Alias Only" in the list options. How do I add my custom lists to the firewall rules and on which interface? LAN or WAN?

Thanks!

URGENT UPDATE:
GPLv2 community rules: also ignore this rule:
2417 PROTOCOL-FTP format string attempt

DISABLED:36
Saw that rule start firing up yesterday. It's a rule from a vulnerability reported in 2007, for XM Easy FTP Server (tsk tsk the software people install these days….). I'm betting 30 years from now, the rule is still there and will be added on my lists. Any takers on that? Seeing the rule here and then go on deleting it is cheating ;)

@lpallard:

It shouldn't create any rules. That means you did not select alias only in the list.

1. I tried accessing some websites that are supposed to be blocked by pfblocker (China, Russia, etc) but I can still access them flawlessly from any machine on my LAN. Why is that?

Blocking by country ranges is something you should never do. Please see:http://forum.pfsense.org/index.php/topic,70453.0.html
@lpallard:

2. pfblocker did not create any rules for my custom lists even if I selected "Alias Only" in the list options. How do I add my custom lists to the firewall rules and on which interface? LAN or WAN?

That's the expected behavior. When selecting alias only, pfblocker knows that it shouldn't create any rule, and all rule setup should be handled by you.
You need a block rule on WAN:
Action: Block
Disabled: NOT ticked
Interface: $wan_interface (select your interface)
TCP/IP Version: VERSION 4!!!! Remember, IPs in those lists are v4 IPs. Don't go creating another rule for v6.
Protocol: Any
Source: not NOT ticked (I hope that makes sence).
In the box under source start typing pfblocker. A tooltip should pop up with an entry in the form pfBlockerCustomAliasName. Select that
Destination; Any
Log: NOT ticked. (there are occasions when you do need to log attempted connections from banned sources, general public use is not one of them)
Description: A description to help you identify this rule.
Hit save.

No go into your LAN (or DMZ,OPT1,SATELLITECONNECTIONTOTHEMOON1 etc..etc..) interface and repeat the above, this time with:
Action: Reject (I don't have to go into why you shouldn't wait for timeouts for the LAN side, you need your applications (browser, remote control exploit etc…etc....) to know they can't connect to a destination immediately. Hitting a bad website will get you an immediate couldn't open the website for example). Oh wait, I did go into.....)
Interface: $lan_interface

I just looked at your screenshots. As far as the countries go, please remove them and stop using pfblocker for that purpose. The pfBlockerTopSpammers rule was created because you didn't select alias only on the list. Please select alias only, remove the rule (if it's not done already) and re-create it using my instructions above.

Why Blocking By Country IP Lists Is Always A Bad Idea.
Back in the early experimental ARPANET days, we pretty much knew Joe was node 1, Clark was node 2, and that's it pretty much.
A couple years later, universities started wanting to get on the (insert ZOMG!!!1111oneeleven look here) Internet Of Things. We reluctanly gave them access, and things went downhill from there on.
Fast forward a couple (or more) decades forward, and the IP pools started getting exhausted. We used to give out /8s back then. Now its a /32 (yea yea, a /32 cannot exist since its a single host etc..etc… look at it from the customer's perspective) IF you are lucky, or told to get access using NAT on an existing IP. The stupidly stubborn Industry Leaders refuse to learn how to use SNI (hosting multiple SSLs on a single IP) and make our work much easier...er... harder HARDER I meant ;). There are even occasions when we actually take IPs from a regional authority (there are 6 and 2 covert ones if I remember them right, too lazy to sideload google) and give them to another. Eg. Africa's one. It hardly used its allocated IPs, while the North American one is almost exhausted. A company acquiring a sizable IP allocation (no, your run of the mill hosting provider is not one of them, coughour creation Google, is cough. Must be getting cold) is free to have that allocation and move it's IPs from country to country. An IP belonging to a European country for example could end up in an Asian country. It takes a lot of effort to keep the lists updated, and is not really worth it. This was, is and will always be Rule Number 1 of why you shouldn't block by country ranges.
There are no such things as Chinese State Sponsored Hackers, or the likes. They don't have the training, and don't put in the effort required to be called a hacker. Hackers are people I have tremendous respect for. Any state sponsored script kiddies are not people I have respect for. Includes the American counterpart, the Pakistan(ese?) counterpart and the Russian counterpart. And pretty much every state sponsored script kiddies. Trust me, the Chinese are not the end all be all ZOMG!!!111oneeleven uber-hackers they are hyped up to be, and no they have no interest in (or actually any way of knowing) your secrets. Up to this point, the good guys are still ahead in the game ;) This is Rule Number 2.
Rule Number 3 is standard. I'm always right, unless I state otherwise.

To recap:
Rules of why blocking by country ranges is bad:

Lists must be kept up to date for the functionality to be maintained.
No such thing as state sponsored hackers. State sponsored script kiddies yes, but that doesn't align with our Keeping You Scared policies. Imagine the news anchor saying "They can't even program a simple "Hello World" program...dramatic pause but they can launch a downloaded exploit against you. We'll take a look into why your computer is not safe...." Doesn't give you that.....how to describe it.... "Chinese dramatic raise of voice hackers end dramatic raise are coming for your data. They have already accessed our country's most TOP SECRET data and are in the process of using sophisticated attacks against commercial entities to get our engineering technology secrets. We'll take a look into why no one is safe against the next generation of Chinese State Sponsored Hackers." See? that did it. Lost my train of thought....were was I?
oh yea,3) I'm always right, unless I state otherwise.

EDIT: Typos
EDIT2: Forgot the disabled rule count.

@jflsakfja:

Saw you writing somewhere that you should reduce your lenghty texts. Please don't, I enjoy reading your curious thoughts very much ;D ;D And as they say, a laugh a day keeps the things away.
