Security Configuration Guides

NSA initiatives in enhancing software security cover both proprietary and open source software, and we have successfully used both proprietary and open source models in our research activities. NSA's work to enhance the security of software is motivated by one simple consideration: use our resources as efficiently as possible to give NSA's customers the best possible security options in the most widely employed products. The objective of the NSA research program is to develop technologic advances that can be shared with the software development community through a variety of transfer mechanisms. NSA does not favor or promote any specific software product or business model. Rather, NSA is promoting enhanced security.

Arudius

Arudius is an information assurance (IA) Linux live CD with tools for penetration testing and vulnerability analysis. IA has many other aspects besides network security. However, it seems that the mainstream public identifies informaion assurance primarily with securing network-enabled systems, so we decided to go with the mainstream and call Arudius a tool for information assurance. The CD consists of a Zenwalk Linux base on top of which a large collection of network security testing software (full list) has been installed - including tools listed on Insecure.org Top 75 list plus many other tools listed on Freshmeat, Sf.net and other information assurance sites around the world.

Virtual Serial Port Driver

A virtual serial port is a trade term used by certain vendors of COM port redirector software that emulates a serial port (RS-232, RS-422, and RS-485). This port is created by special software products which enable extra serial ports in operation system without additional hardware installation (such as expansion cards, etc.). Unlike the standard physical serial port the virtual one can be assigned any name (COM255, VSP33, etc.) to. It is possible to create unlimited number of virtual serial ports in your PC. The only limitation is the performance capacity of your system, as it may require a substantial amount of resources to emulate say 255 serial ports on slow computers.

Virtual serial port emulates all serial port functionality, including Baud rate, Data bits, Parity bits, Stop bits, etc. Additionally it allows controlling the data flow, emulating all signal lines (DTR/DSR/CTS/RTS/DCD/RI) and customizing pinout (only advanced solutions).

Serial ports emulation can be useful in case there is a lack of available physical serial ports or they do not meet the current requirements. For instance, virtual serial ports can help you share data between several applications from one GPS device connected to serial port. Another option is to communicate with any other serial devices via internet or LAN as if they are locally connected to computer (Serial-over-Ethernet technology). You can establish connection between two computers or applications via emulated null-modem link. Most of the available virtual serial port emulators are compatible with Windows 9x, Windows NT, Windows 2000, Windows ME, Windows 2003, Windows XP and some of them run under Windows CE, Windows Mobile and Pocket PC.

Virtual serial ports are available as both commercial products and free software.

Virtual Serial Port Driver (VSPD) turns serial ports of Tibbo Device Servers into remote COM ports of your PC. VSP Manager is used to create and manage Virtual Serial Ports (VSPs).

Medusa Parallel Network Login Auditor

Medusa is intended to be a speedy, massively parallel, modular, login brute-forcer. The goal is to support as many services which allow remote authentication as possible. The author considers following items as some of the key features of this application:

* Thread-based parallel testing. Brute-force testing can be performed against multiple hosts, users or passwords concurrently.
* Flexible user input. Target information (host/user/password) can be specified in a variety of ways. For example, each item can be either a single entry or a file containing multiple entries. Additionally, a combination file format allows the user to refine their target listing.
* Modular design. Each service module exists as an independent .mod file. This means that no modifications are necessary to the core application in order to extend the supported list of services for brute-forcing.

Beryl

Beryl is a combined window manager and compositing manager that runs on top of Xgl or AIGLX using OpenGL to provide effects accelerated by a 3D graphics card on the desktop.


What is the difference between freedesktop.org compiz and beryl?

* Uses flat file backend instead of gconf meaning almost no gnome dependency.
* Needs "beryl-settings", an application to configure settings instead of gconf-editor.
* Has a lot of extra plugins and enhanced features in other plugins.
* Starts with beryl-manager.
* Has a themeable decorator (emerald).
* Has a theme manager (emerald-themer).
* Changes frequently: new features are added on a daily basis.
* Made by a community right here at forum.beryl-project.org, although submissions of extra plugins and enhancements from here to freedesktop would make the compiz better over all.

Spamer was condemned in Virginia

The Court of Appeals of Virginia upheld yesterday what is believed to be the first conviction in the nation under a state anti-spamming law that makes it a felony to send unsolicited mass e-mails.

A North Carolina man was convicted in Loudoun County two years ago of illegally sending tens of thousands of e-mails to America Online customers. Prosecutors said Jeremy Jaynes flooded the servers at the Internet company's headquarters in Loudoun with bulk e-mail advertisements for computer programs and stock pickers.

Jaynes was sentenced last year to nine years in prison on three counts of violating the state's anti-spam law and was allowed to remain free on $1 million bond while his case was appealed. Thomas M. Wolf, an attorney for Jaynes, said he plans to appeal yesterday's decision.

Splitting Large Files to Span Multiple Disks using TAR

The two extra command line options you need to use over and above the standard syntax are -M (--multi-volume) which tells Tar you want to split the file over multiple media disks. You then need to tell Tar how big that media is, so that it can create files of the correct size. To do this you use the --tape-length option, where the value you pass is number x 1024 bytes.

The example below shows the syntax used. Lets say the largefile.tgz is 150 Meg and we need to fit the file on two 100 Meg Zip drives.

tar -c -M --tape-length=102400 --file=disk1.tar largefile.tgz

The value 102400 is 1024 x 100, which will create a 100 Meg file called disk1.tar and then Tar will prompt for volume 2 like below :-

Prepare volume #2 for disk1.tar and hit return:

In the time of tape drives you would have taken the first tape out of the machine and inserted a new tape, and pressed returned to continue. As we want Tar to create the remaining 50 Meg in a separate file, we issue the following command :-

n disk2.tar

This instructs Tar to continue writing the remaining 50 Meg of largefile.tgz to a file named disk2.tar. You will then be prompted with the line below, and you can now hit return to continue.

Prepare volume #2 for disk2.tar and hit return:

You would repeat this process until your large file has been completely processed, increasing the disk number in the file each time you are prompted.

Other example:
tar cvf arq1.tar -M --tape-length=500000 bigarq.txt


Putting the File Back Together

The process is similar when putting the large file back together from its split-up files. Below is the syntax used to re-create the large file from the disk1.tar and disk2.tar images.

C:\tar>tar -x -M --file=disk1.tar largefile.tgz
Prepare volume #2 for disk1.tar and hit return: n disk2.tar
Prepare volume #2 for disk2.tar and hit return:

Comparison of Linux distributions

The many available Linux distributions differ for a range of reasons including technical, organizational, and philosophical.

Technical variations include support for different hardware devices and systems or software package configurations. Organizational differences may be motivated by technical decisions but also by philosophical or even historical reasons. Some distributions specialise in use on desktops, servers or routers. Other criteria include security, including how quickly security upgrades are available; ease of package management; and number of binary packages available.

These tables compare the latest stable release of major distributions on a range of objective criteria. It does not cover the subjective merits of each operating system, branches marked as unstable/beta, nor compare Linux distributions with other operating systems.

Warsaw's Laws of Hackering

In the great tradition of Murphy's Law and other related laws, I offer my humble few. I'm not sure I have rightful claim to originating all these, so if you find a previous reference to these laws, please let me know!

Warsaw's First Law: The Rule of Estimate Accuracy Insurance
When making a time estimate for any programming task, make your best formalized guess, then multiply by two and bump it up a unit. E.g. "I think it will take me three days to hack in those changes to the frobnicator"; My official estimate: 6 weeks.

Warsaw's Second Law: Unbending Law of Commit Scheduling
Never change anything after 3pm on a Friday.

Corollary to Warsaw's Second Law
If you do change anything after 3pm on Friday, you will break it, and thus end up fixing it for the entire weekend. You will probably not be able to sleep, and if you do fall asleep, you will dream about the breakage. On Monday morning, you will fix the problem in five minutes.

Warsaw's Third Law: Law of Software in a Vacuum
All software sucks. Make sure yours sucks less.

Warsaw's Fourth Law: The Law of Pinball Machine Instructions
It doesn't matter a wit if the instructions are printed clearly for all to see, nobody will read them. They'll just drop their quarters and start pushing buttons like a Tommy. Software is the same.

Warsaw's Fifth Law: A Rose By Any Other Name (a.k.a the Pink Floyd Rule)
All names are stupid until you become rich and famous with it.

The Ten Most Critical Wireless and Mobile Security Vulnerabilities

1. Default WiFi routers: By default, wireless routers are shipped in an un-secured state.

2. Rogue Access Points: set up an authorized access point, without informing the network administrator.

3. Wireless Zero Configuration: When a computer connects to an access point, it generally stores the details of that connection locally. The next time the computer is turned on, the wireless network card immediately looks for the connection and re-establishes the connection. Since the SSID value is sent as plain text, anyone with a sniffer can see it. Programs like Karma automate this process.

4. Bluetooth exploits: BlueSnarfing, BlueBugging, BlueJacking, BlueTooth DoS attacks.

5. WEP Weaknesses: passwords can easily be cracked using Airsnort.

6. Clear Text Encryption Passwords: Some of the most popular mobile encryption programs even store the password in plain text in the registry.

7. Malicious Code: "Airborne" mobile viruses.

8. Autorun: Windows Mobile devices contain a little-known autorun feature that can provide an attacker with a quick and easy method of infection. When a media card is inserted into the PDA, Windows Mobile will copy over the autorun.exe (if it exists), create a copy in the /Windows directory, and execute it. A user can prevent this by creating a read-only dummy executable called autorun.exe and put it in the /Windows folder.

9. Multiple VoIP attacks: VoIP is mostly sent in an unencrypted format. As a result, anyone can see the connection information and capture/record the conversation. Programs like VoMiT and Cain & Abel can easily capture and record conversations. Other programs like sipbomber can kick a user offline. In addition, SiVus (a VoIP scanner) can quickly locate VoIP enabled systems.

10. Lost and stolen devices: All mobile databases should be encrypted. A good, written security policy and user education are also important. Mobile devices should all have a login copyright banner, along with return information.

nUbuntu

The main goal of nUbuntu is to create a distribution which is derived from the Ubuntu distribution, and add packages related to security testing, and remove unneeded packages, such as Gnome, Openoffice.org, and Evolution. nUbuntu is the result of an idea two people had to create a new distribution for the learning experience. Many people ask, "What makes it better than X?", or "Why should I use this over Y". Our answer to this question is, we do not think about whether people are using it or not. We are more concerned about the learning process. If you want to try something with a clean interface, fast, and an excellent range of programs please don't hesitate to download nUbuntu.

Linux wireless LAN support

This is an attempt to create a, more or less complete listing of wireless devices with information about the chipset they are based on and whether or not they are supported in Linux. The basis of this list came from this list.
This list isn't complete, so if you have any information about a wireless card, its chipset and whether or not it is supported, please help to support.
This list doesn't specify anything about how much of your card is supported. So a card that only works without encryption is listed the same as one that also has support for WEP/WPA. For the specifics about how much of your card is supported, please refer to the driver page listed for your card.

Linux Performance Tuning

When a distribution is packaged and delivered to clients, it is designed to be fully compatible with most of the computers available in the market. This is a very heterogeneous set of hardware (hard disks, video cards, network cards, etc.). So distribution vendors like Red Hat, SuSe, Mandriva and the rest of them choose some conservative configuration options to assure a successful installation.

Squid Result Codes

TCP_HIT
A valid copy of the requested object was in the cache.

TCP_MISS
The requested object was not in the cache.

TCP_REFRESH_HIT
The requested object was cached but STALE. The IMS query for the object resulted in "304 not modified".

TCP_REF_FAIL_HIT
The requested object was cached but STALE. The IMS query failed and the stale object was delivered.

TCP_REFRESH_MISS
The requested object was cached but STALE. The IMS query returned the new content.

TCP_CLIENT_REFRESH_MISS
The client issued a "no-cache" pragma, or some analogous cache control command along with the request. Thus, the cache has to refetch the object.

TCP_IMS_HIT
The client issued an IMS request for an object which was in the cache and fresh.

TCP_SWAPFAIL_MISS
The object was believed to be in the cache, but could not be accessed.

TCP_NEGATIVE_HIT
Request for a negatively cached object, e.g. "404 not found", for which the cache believes to know that it is inaccessible. Also refer to the explainations for negative_ttl in your squid.conf file.

TCP_MEM_HIT
A valid copy of the requested object was in the cache and it was in memory, thus avoiding disk accesses.

TCP_DENIED
Access was denied for this request.

TCP_OFFLINE_HIT
The requested object was retrieved from the cache during offline mode. The offline mode never validates any object, see offline_mode in squid.conf file.

UDP_HIT
A valid copy of the requested object was in the cache.

UDP_MISS
The requested object is not in this cache.

UDP_DENIED
Access was denied for this request.

UDP_INVALID
An invalid request was received.

UDP_MISS_NOFETCH
During "-Y" startup, or during frequent failures, a cache in hit only mode will return either UDP_HIT or this code. Neighbours will thus only fetch hits.

NONE
Seen with errors and cachemgr requests.

The following codes are no longer available in Squid-2:

ERR_*
Errors are now contained in the status code.

TCP_CLIENT_REFRESH
See: TCP_CLIENT_REFRESH_MISS.

TCP_SWAPFAIL
See: TCP_SWAPFAIL_MISS.

TCP_IMS_MISS
Deleted, TCP_IMS_HIT used instead.

UDP_HIT_OBJ
Hit objects are no longer available.

The table of equivalents / replacements / analogs of Windows software in Linux

One of the biggest difficulties in migrating from Windows to Linux is the lack of knowledge about comparable software. Newbies usually search for Linux analogs of Windows software, and advanced Linux-users cannot answer their questions since they often don't know too much about Windows :). This list of Linux equivalents / replacements / analogs of Windows software is based on our own experience and on the information obtained from the visitors of this page (thanks!).

This table is not static since new application names can be added to both left and the right sides. Also, the right column for a particular class of applications may not be filled immediately. In future, we plan to migrate this table to the PHP/MySQL engine, so visitors could add the program themselves, vote for analogs, add comments, etc.
