Mistakes People Make that Lead to Security Breaches

The Five Worst Security Mistakes End Users Make

Failing to install anti-virus, keep its signatures up to date, and apply it to all files.

Opening unsolicited e-mail attachments without verifying their source and checking their content first, or executing games or screen savers or other programs from untrusted sources.

Failing to install security patches-especially for Microsoft Office, Microsoft Internet Explorer, Firefox, and Netscape.

Not making and testing backups.


Being connected to more than one network such as wireless and a physical Ethernet or using a modem while connected through a local area network.

In the above pastebin-post, the following is stated:

If you entered the Anonymous IRC-network at the time this was posted, the topic of channel opGlobalBlackout was: Official Press Release: http://pastebin.com/yK79Tsgq

As you can see, the "Press Release" tells potential Anonymous-members to stop waging war, that peace is the way to go, to stop DDoS-attacks. This is another words an "anti-op" designed to get potential anonymous-recruits to think about what they are doing.

There never was an operation. There was only an anti-operation, designed to get people to think.

http://www.washingtontimes.com/news/2011/oct/20/cybercommand-chief-opposes-un-net-control/

Cybercommand chief opposes U.N. net control
‘Government survivability’ issue

BALTIMORE — The commander of the U.S. Cyber Command said Thursday that he does not favor giving the United Nations the power to regulate the Internet.

Some regulations are needed to protect critical networks that control electrical power, banking, transportation and other key elements of society, Army Gen. Keith Alexander, who is also director of the National Security Agency, said after a speech to a security conference.

But asked whether the U.N. should have a regulation role, Gen. Alexander said: “No. I’m not for regulating, per se. I’m concerned about it, and this is a tough question. I would say, generally speaking, I’m not into that portion of regulating as you would espouse.”

Last month, Russia, China, Uzbekistan and Tajikistan submitted a resolution to the U.N. General Assembly calling for giving individual states the right to control the Internet. The resolution, submitted Sept. 14, calls for “an international code of conduct for information security.”

It requests “international deliberations within the United Nations framework on such an international code, with the aim of achieving the earliest possible consensus on international norms and rules guiding the behavior of states in the information space.”

China tightly controls the Internet through a cybersecurity police force estimated to be more than 10,000 people who monitor Internet users and websites.

Russia’s authoritarian government has taken steps in recent years to curb Internet freedoms. Uzbekistan and Tajikistan also are authoritarian regimes that seek to control Internet use.

Gen. Alexander said that, rather than seeking U.N. regulation, individual countries “first need to step up and say, ‘Look, how do we do this without regulating it?’ “

The four-star general suggested bolstering Internet security by using “cloud” technology, which uses remote computer servers for applications and data storage. Other new technologies that permit greater visibility of cyberthreats on networks also can be used to improve security, he said.

“I do think that there may be some things for critical infrastructure and government networks that we’re going to have to direct out to the government,” Gen. Alexander said. “These are things that you must do to secure your networks for government survivability.”

Additionally, security cooperation between nations can be improved, he said.

“But for my grandchildren and my daughters out there, they have a great time on the network,” he said. “I would not want somebody to say you cannot let your 2-year-old grab the iPad and launch [an application].”

As for future considerations, Gen. Alexander said U.S. policymakers are discussing whether U.S. firms should be required to divulge information about cyber-attacks.

Additionally, he said: “I think down the road we have to figure out how do we ensure that your platforms do not create a public hazard, but I’m not sure I would put that in regulation.”

In a speech to the Information Systems Security Association conference, Gen. Alexander said U.S. development of the Internet brought tremendous benefits and “tremendous vulnerabilities” that can be exploited by hackers, criminals and nation states.

U.S. corporations were victims of cyber-attacks, including Google, Lockheed Martin and Booz Allen Hamilton, and some have lost valuable intellectual property through cybertheft and espionage.

The threat is increasing as the use of mobile devices such as smartphones and tablet computers increases.

“Here’s what concerns me: What we’re seeing is destructive [digital] payloads coming out, payloads that can make a blue screen of death, that can stop your operating system, your router or peripheral devices,” Gen. Alexander said.

Mobile devices increase the problem by “orders of magnitude” because of the lack of security built up over the past decade for desktop devices, he said.

Both are connected to networks, “and the issues we are going to see are huge,” Gen. Alexander said.

Shawn Henry, FBI executive assistant director for cyber-issues and a conference speaker, said a better network architecture is needed to identify cybercriminals who can operate anonymously.

Mr. Henry also called for better “assurance” for Internet communications to prevent someone from breaking into links that control key infrastructure. For example, computer communications between a technician remotely directing an electrical facility need better security, he said.

“The Internet was developed with protocols allowing for anonymity and there are legitimate reasons for wanting it that way,” Mr. Henry said. “But for those critical uses of the Internet where intrusion is entirely unacceptable and we must be able to identify the users, market-driven factors may prompt the private sector to explore solutions and alternate architectures to meet those needs.”

“We need a more secure architecture that allows for absolute attribution,” he said. “Threats are continuing to increase and we cannot constantly play defense.”

Got this from http://offgridsurvival.com/shtfsurvivalmanual/   - I like this idea.

Electronic storage is great, for years I have recommended things like survival laptops and tablets. With a good solar charger these devices can last for years in an off the grid environment.
If your anything like most of the survival minded people that come to this site, you probably bookmark and save a ton of good survival articles. While I love electronic devices, when the SHTF you need to have backups of all your valuable survival information.
You need your own SHTF Proof Survival Manual.
Lately I have been saving a ton of how to articles to my NOOK but I don’t stop there. The nook is great for storing survival books and articles but I also started laminating the most important articles and putting them into my own personal survival manual.
For under $40 bucks you can make yourself a good SHTF proof survival binder.
First, you need to buy a good laminator and a pack of lamination sheets.
You can get a Good Laminator on Amazon and a pack of 50 lamination sheets for around $40. This will allow you to put about 400 articles in your personal survival manual.
Second, I condense the articles down so I can fit at least 4 to a page (8 double sided) this gives you roughly 400 articles with only 50 pieces of paper. Remember the lamination adds some weight so you don’t want to go crazy here. Print only those articles that you think you will really need post SHTF.
I usually condense articles down in Microsoft word, or I shrink down specific pages from books so I can fit them into my 4up format. I then 3 ring punch the laminated pages and put them in a good zippered binder to protect them from the elements.
What kinds of articles do I add to my personal survival manual?
My NOOK can pretty much hold everything I need so I fill that up with as much information as I can get. For my Binder I take only the things that I think I will need in a post SHTF world.
Maps, Evacuation Routes and Bug Out Locations
Medical information and first aid instructions
How To articles
Pictures of edible plants
Communication frequency charts, notes and antenna diagrams / formulas
Primitive Skills & instructional materials
Trapping Diagrams
And anything that you may have a hard time remembering

New show on Discovery called The Colony.

http://dsc.discovery.com/videos/the-colony-the-experiment-begins.html

A new program on The Discovery Channel, The Colony is a reality TV show that puts several people in a simulated post-apocalyptic environment. The official website describes the show this way:

What would you do in the wake of a global catastrophe? How would you find food? Water? Shelter?

The Colony is a controlled experiment to see exactly what it would take to survive and rebuild under these circumstances. For 10 weeks, a group of 10 volunteers, whose backgrounds and expertise represent a cross-section of modern society, are isolated in an urban environment outside Los Angeles and tasked with creating a livable society.

With no electricity from the grid, no running water and no communication with the outside world, all the volunteers have to work with are their skills and whatever tools and supplies they can scavenge from their surroundings.

Episode One focused on establishing the setting, as well as introducing the cast. The "survivors" include a martial artist, a doctor, and a computer engineer, among others. So far, they've had to scavenge for supplies at a destroyed shopping mall, defend their stash from marauders, find shelter, and find water. As we all know, water is one of the most important things any living creature needs to survive, and the nearby L.A. river's water wasn't at all safe to drink. Not until computer engineer John Cohn rigged a filtration system using alternating layers of sand and charcoal in a plastic trash can. From there, the survivors were able to boil the filtered water, making it potable.

When the show was in production, Paladin Press provided the producers with a good supply of books dealing with survival topics. One, Ragnar's Urban Survival: A Hard-Times Guide to Staying Alive in the City by Ragnar Benson, has a chapter specifically about finding, collecting, storing, and purifying water in an urban environment once society has collapsed. It includes a diagram of a sand filter that anyone can make, not at all unlike John's construction, as well as how to purify water with bleach. Being prepared doesn't mean waiting until a disaster has already happened to act: it's about having a plan, supplies, and the knowledge to get yourself and your family out of a jam.

Taking to the Streets — and Tweets — in Tehran
By Nathan Hodge   June 13, 2009  |  3:34 pm  |  Categories: Info War, Rogue States
Iranians are taking to the streets to protest the re-election of President Mahmoud Ahmadinejad. While Ahmadinejad’s rivals claimed widespread electoral fraud — and appealed for Ayatollah Ali Khamenei, Iran’s supreme leader, to intervene. Khamenei, however, appeared on state television today to congratulate Ahmadinejad on his victory.

It appears the authorities may have blocked text messaging, a key organizing tool of opposition candidates like Mir Hossein Mousavi. Twitter users reported that SMS service had gone offline just before polls opened.

Game over? Not quite. Iranians have organized protests in Tehran, and some demonstrators are using social media to post video and updates. Here’s a recent YouTube post:



The National Iranian American Council in Washington is liveblogging the election, and they have translations of some of the Farsi Twitter streams. Check it out.

Aquaponics is a bio-integrated system that links recirculating aquaculture with hydroponic vegetable, flower, and/or herb production. Recent advances by researchers and growers alike have turned aquaponics into a working model of sustainable food production. This publication provides an introduction to aquaponics with brief profiles of working units around the country. An extensive list of resources point the reader to print and Web-based educational materials for further technical assistance.

Introduction

Aquaponics, also known as the integration of hydroponics with aquaculture, is gaining increased attention as a bio-integrated food production system.

Aquaponics serves as a model of sustainable food production by following certain principles:

The waste products of one biological system serve as nutrients for a second biological system.
The integration of fish and plants results in a polyculture that increases diversity and yields multiple products.
Water is re-used through biological filtration and recirculation.
Local food production provides access to healthy foods and enhances the local economy.
In aquaponics, nutrient-rich effluent from fish tanks is used to fertigate hydroponic production beds. This is good for the fish because plant roots and rhizobacteria remove nutrients from the water. These nutrients – generated from fish manure, algae, and decomposing fish feed – are contaminants that would otherwise build up to toxic levels in the fish tanks, but instead serve as liquid fertilizer to hydroponically grown plants. In turn, the hydroponic beds function as a biofilter – stripping off ammonia, nitrates, nitrites, and phosphorus – so the freshly cleansed water can then be recirculated back into the fish tanks. The nitrifying bacteria living in the gravel and in association with the plant roots play a critical role in nutrient cycling; without these microorganisms the whole system would stop functioning.

Greenhouse growers and farmers are taking note of aquaponics for several reasons:

Hydroponic growers view fish-manured irrigation water as a source of organic fertilizer that enables plants to grow well.

Fish farmers view hydroponics as a biofiltration method to facilitate intensive recirculating aquaculture.

Greenhouse growers view aquaponics as a way to introduce organic hydroponic produce into the marketplace, since the only fertility input is fish feed and all of the nutrients pass through a biological process.

Food-producing greenhouses – yielding two products from one production unit – are naturally appealing for niche marketing and green labeling.

Aquaponics can enable the production of fresh vegetables and fish protein in arid regions and on water-limited farms, since it is a water re-use system.

Aquaponics is a working model of sustainable food production wherein plant and animal agriculture are integrated and recycling of nutrients and water filtration are linked.

In addition to commercial application, aquaponics has become a popular training aid on integrated bio-systems with vocational agriculture programs and high school biology classes.
The technology associated with aquaponics is complex. It requires the ability to simultaneously manage the production and marketing of two different agricultural products. Until the 1980s, most attempts at integrated hydroponics and aquaculture had limited success. However, innovations since the 1980s have transformed aquaponics technology into a viable system of food production. Modern aquaponic systems can be highly successful, but they require intensive management and they have special considerations.

This publication provides an introduction to aquaponics, it profiles successful aquaponic greenhouses, and it provides extensive resources. It does not attempt to describe production methods in comprehensive technical detail, but it does provide a summary of key elements and considerations.

Aquaponics: Key Elements and Considerations

A successful aquaponics enterprise requires special training, skills, and management. The following items point to key elements and considerations to help prospective growers evaluate the integration of hydroponics with aquaculture.

Hydroponics: Hydroponics is the production of plants in a soilless medium whereby all of the nutrients supplied to the crop are dissolved in water. Liquid hydroponic systems employ the nutrient film technique (NFT), floating rafts, and noncirculating water culture. Aggregate hydroponic systems employ inert, organic, and mixed media contained in bag, trough, trench, pipe, or bench setups. Aggregate media used in these systems include perlite, vermiculite, gravel, sand, expanded clay, peat, and sawdust. Normally, hydroponic plants are fertigated (soluble fertilizers injected into irrigation water) on a periodical cycle to maintain moist roots and provide a constant supply of nutrients. These hydroponic nutrients are usually derived from synthetic commercial fertilizers, such as calcium nitrate, that are highly soluble in water. However, hydro-organics – based on soluble organic fertilizers such as fish hydrosylate – is an emerging practice. Hydroponic recipes are based on chemical formulations that deliver precise concentrations of mineral elements. The controlled delivery of nutrients, water, and environmental modifications under greenhouse conditions is a major reason why hydroponics is so successful.

Nutrients in Aquaculture Effluent: Greenhouse growers normally control the delivery of precise quantities of mineral elements to hydroponic plants. However, in aquaponics, nutrients are delivered via aquacultural effluent. Fish effluent contains sufficient levels of ammonia, nitrate, nitrite, phosphorus, potassium, and other secondary and micronutrients to produce hydroponic plants. Naturally, some plant species are better adapted to this system than others. The technical literature on aquaponics provides greater detail on hydroponic nutrient delivery; especially see papers cited in the Bibliography by James Rakocy, PhD.

Plants Adapted to Aquaponics: The selection of plant species adapted to hydroponic culture in aquaponic greenhouses is related to stocking density of fish tanks and subsequent nutrient concentration of aquacultural effluent. Lettuce, herbs, and specialty greens (spinach, chives, basil, and watercress) have low to medium nutritional requirements and are well adapted to aquaponic systems. Plants yielding fruit (tomatoes, bell peppers, and cucumbers) have a higher nutritional demand and perform better in a heavily stocked, well established aquaponic system. Greenhouse varieties of tomatoes are better adapted to low light, high humidity conditions in greenhouses than field varieties.

Fish Species: Several warm-water and cold-water fish species are adapted to recirculating aquaculture systems, including tilapia, trout, perch, Arctic char, and bass. However, most commercial aquaponic systems in North America are based on tilapia. Tilapia is a warm-water species that grows well in a recirculating tank culture. Furthermore, tilapia is tolerant of fluctuating water conditions such as pH, temperature, oxygen, and dissolved solids. Tilapia produces a white-fleshed meat suitable to local and wholesale markets. The literature on tilapia contains extensive technical documentation and cultural procedures. Barramundi and Murray cod fish species are raised in recirculating aquaponic systems in Australia.

Tilapia is a warm-water species that grows well in a recirculating tank culture.
Water Quality Characteristics: Fish raised in recirculating tank culture require good water quality conditions. Water quality testing kits from aquacultural supply companies are fundamental. Critical water quality parameters include dissolved oxygen, carbon dioxide, ammonia, nitrate, nitrite, pH, chlorine, and other characteristics. The stocking density of fish, growth rate of fish, feeding rate and volume, and related environmental fluctuations can elicit rapid changes in water quality; constant and vigilant water quality monitoring is essential.

Biofiltration and Suspended Solids: Aquaculture effluent contains nutrients, dissolved solids, and waste byproducts. Some aquaponic systems are designed with intermediate filters and cartridges to collect suspended solids in fish effluent, and to facilitate conversion of ammonia and other waste products to forms more available to plants prior to delivery to hydroponic vegetable beds. Other systems deliver fish effluent directly to gravel-cultured hydroponic vegetable beds. The gravel functions as a “fluidized bed bioreactor,” removing dissolved solids and providing habitat for nitrifying bacteria involved in nutrient conversions. The design manuals and technical documentation available in the Resources section can help growers decide which system is most appropriate.

Component Ratio: Matching the volume of fish tank water to volume of hydroponic media is known as component ratio. Early aquaponics systems were based on a ratio of 1:1, but 1:2 is now common and tank: bed ratios as high as 1:4 are employed. The variation in range depends on type of hydroponic system (gravel vs. raft), fish species, fish density, feeding rate, plant species, etc. For example, the Speraneo system described below is designed for one cubic foot of water to two cubic feet of grow bed media (pea gravel). Further, when shallow bed systems only three inches in depth are employed for the production of specialty greens such as lettuce and basil, the square footage of grow space will increase four times. Depending on the system design, the component ratio can favor greater outputs of either hydroponic produce or fish protein. A “node” is a configuration that links one fish tank to a certain number of hydroponic beds. Thus, one greenhouse may contain a multiple number of fish tanks and associated growing beds, each arranged in a separate node.

There are a couple Yahoo Discussion groups I belong to that are a valuable resource for info the first one you might be interested in is the aeroponics_aquaponics group which has allot of info on Barrelponics which are usually very small systems a good one for you to start out with. Another group I belong to is aquaponicfarm Group which has allot of info on larger systems and homemade equipment such as diagrams for wind powered pumps and such.

Cycling between fish harvest is not really an issue on an established tank. The more problematic one is the initial start of your system. I like to start off with Goldfish, if they die no big deal because they are very cheap. Some aquaponics set ups use a very high ratio of fish per gallon of water. I've seen up to 1 fish per gallon but many things can go wrong quickly with that dense of a population. I have had best results in 1 - 1 1/2 Lb. fish per 4 gallons of water but it differs from the size of fish that is going to be raised
.

OK. Ill be checking that out later today, thanks for the info.

Well I am here to inspire...

I really believe this is one of the most viable farming methods on earth. In Ca. we are having a major water shortage and becoming a problem for traditional farmers. Most Aquaponic farms use 10% of the water regular farming methods use per acreage and can grow up to 44% more produce. There are no nutrient run off that can go into the environment which regular farming has a major problem with. The system if run by solar power or wind power it has almost 0 impact on the environment other than taking water out of it but in my system I only go thru 15 gallons a day which is less than a shower.

With this system you also have the benefit of harvesting some type of freshwater species. Most systems use Tilapia but you can use any freshwater creature that poops. You can use Trout, Bass, Fresh Water Prawn, Crawfish, Catfish the list goes on. Some people even use gold fish or Koi. Koi is a more viable fish to use because you can sell Koi at a high price but Goldfish are pretty much a waste of space you can't eat them and they don't sell for much.

The system works fairly simple...The fish effluent is pumped into grow beds using some sort of substrate usually pea gravel. Then a bacteria called Notrosomonas converts ammonia into nitrites and another bacteria named Nitrobacter converts the nitrite to nitrate which is consumed by the plants. The water then is drained into a return tank and then pumped back into the fish tank and is 97% pure water when it has gone thru the grow beds.

Tilapia is one of the most popular fish to use because it is a warm water fish and the system does better because the bacteria like it warm. For most of the year average water temp. is around 82 degrees which the bacteria thrive in. Also Tilapia is a very fast growing fish where it can become full size within 7-12 months averaging around a pound and a half.

Well I will leave you with this much info for now if any body has any questions about it feel free to ask.

Ah well.. that answered some questions.  I was wondering why some people used Koi. Fortunately Im in Hawai'i so the weater is usually pretty warm and so I believe well start with Tilapia. Ive seen some kits that have the option of using solar again being in Hawaii I think that would be the obvious choice  I am also interested in trying out some other type of fish too.  

We are also thinking about starting an adult foster home and using the Aquaponic garden to raise most of our vegetables and gardens but first I wanna get a small kit / or make our own and start small.  Eventually once I get going and feel comfortable we thought about contacting homeless shelters (possibly provided some food for the shelter) and / or sell fish and veggies at the farmers market and / or get involved with a co-op.

Oh.. what about the cycle betweeen harvesting the fish and adding new fish i.e. initially start with 15 fish and then maybe 60 days later add in more?

Mahalo Shaggy Dog!

 Obama Now Wants Your Pocket Knife
by Evan F. Nappen, Esq.

June 4, 2009

Beware! That folding knife in your pocket may turn you into a criminal if the Obama administration gets its way. Although there has been a lot of fear and speculation that the new administration wants to take your guns, the most pressing threat now is actually to your pocket knives. With the changing of the guard at U.S. Customs, that agency has now embarked on redefining "switchblades" under federal law to include a wide variety of one hand opening knives that never were intended to be prohibited. In fact, many of the knives U.S. Customs now seek to prohibit under the Federal Switchblade Law had not even been invented at the time of its enactment! Furthermore, four previous U.S. Customs ruling letters (prior administrations) specifically determined "assisted opening" knives not to be defined as switchblades.

This new proposed U.S. Customs regulation is so broad that thousands of pocket knives will fall under its sweep and millions of knife owners will be affected. The problem is not simply that imports will be banned (which is bad enough), but that the "agency determination" will be used by domestic courts and law enforcement to determine what a "switchblade" is under both federal and state laws. Many states, including New Hampshire, fail to define switchblades and simply rely on the federal definition.

Luckily, the two premiere knife organizations in the US, American Knife and Tool Institute (AKTI) and Kniferights.org, are fighting hard on this issue, but they both need your immediate help. Customs is attempting to jam this new regulation though at record speed.

As stated on the www.kniferights.org website:

    U.S. Customs has proposed revoking earlier rulings that assisted opening knives are not switchblades. The proposed new rule would not only outlaw assisted opening knives its broad definition could also easily be interpreted to include one-handed opening knives and even most other pocket knives.

    Note that customs interpretation of the Federal Switchblade Act forms the basis for national, state and even local law and judicial rulings in many cases. The effect is NOT limited to just imports.

As stated on the www.akti.org website:

    URGENT NEWS - U.S. Customs Proposal would characterize assisted-openers as switchblade knives and jeopardize all pocket knives.  On behalf of the entire sporting knife industry and knife owners across the country, AKTI will be filing an official response to U.S. Customs.   

This is the biggest threat to American knife owners in U.S. history. AKTI informs us that this "Customs' proposal will make criminal out of 35.6 million Americans."

AKTI further states:

    U.S. Customs proposes to bypass Congress and expand the switchblade definition to include all knives that open with one hand. These include multi-tools, traditional pocket knives, one-hand openers, and assisted-openers.
    More than 35.6 million law-abiding Americans now own one-hand-openingknives in one of the above four categories.

The U.S. Customs proposed new rule and the four prior letters they want to overturn can be read in their entirety here: http://www.akti.org/PDFS/U.S.CustomsProposedRuling.pdf

AKTI suggests that to register your opposition to the U.S. Customs'plan (19  CFR  Part 177) to re-classify assisted openers and all folding knives; address your comments by June 21, 2009, to:

    19  CFR  Part 177

I've seen Shaggy's setup.  It's quite impressive.  I wish I'd had my camera with me! 

Oooh maybe I can email him for tips and suggestions!

Shaggy Dog does something quite like this too in his backyard in the San Fernando Valley in Los Angeles.  For the fish, he uses Tilapia, which are an excellent clean protein source as well.

Actually, I got the idea after reading a post from Shaggy to DogZilla on Facebook.  After doing some research there is a farm here on Oahu that has classes as well as a family on the big island that does it commercially.  I think we will start out with Tilapia but I have also been reading that other people use Koi, Crawdads, Goldfish, and Perch.  Interesting stuff. The more I read the more excited I get. 

A small step to being self sufficient.

(geez, just realized that I totally misspelled the subject)

Im not entirely sure where this fits in it could be environmental but it is also a part of health.  My girlfriend and I have been seriously looking into Aquaponics. Anyone else do / tried this?
