Why should you use Rent-A-Geeks for your disaster recovery drills?

Why should you use Rent-A-Geeks for your disaster recovery drills?

 

The pushback I get on this one topic is phenomenal.  Their IT people who know their boss better than I, always question the need for a disaster recovery audit in the first place.

“I Get it!  To them, that is synonymous with taking your shoebox full of tax information to the IRS and asking them for an audit. Please let me suffer through an audit because I love pain!”

So who in their right mind would do it?

I can think of no better argument than Puerto Rico.  That island was wiped off the map.  They have no power grid left.  They have no data communications and let’s face it; It will take years for them to recover.

I had customers there, but I bet that those businesses may no longer be viable.

They are requesting of all things truck drivers, among their many lists of needs.  Why?

Their truck drivers were affected by the buss’s called Irma and then Maria.

I am speaking to the owners of businesses with this next sentence. “Folks, your IT guy that tells you that you don’t need an outside firm or audit, is setting you up for disaster.”

Objectivity is essential.  You need an honest assessment by someone who does not have a dog in that fight.

If a team of rent-a-geeks cannot restore your company at a warm site, the DR plan that you think you have is worthless. It may satisfy the ISO folks or the other government or banking or insurance companies, but the sad truth is, in an actual Disaster your people may not be around to add their collective knowledge to the process.

One client did not even look at one I prepared for them.  When I asked if he wanted to go over it he shook his head.  “No, I just need something for the auditor to show that we have one.”

My reports go to you the customer, nowhere else.  My recommendations are put forth in a clear, concise manner that you will not need your IT guy to explain to you.  Read and understand my blogs on the topic and then ask the critical questions.  If you hold your SA’s feet to the fire or your CIO’s feet to the fire, you will far better off than most of the firms I deal with.

One firms CIO that I worked with was not suited for desktop wizard much less the end all be all guru of all things technology.  Now if numbers are what interested the CEO, this was his guy.  He could pinch a nickel with the best of them. “Penny wise pound foolish,” should be on this man’s card.

It does not take an Irma or Maria to sink your business.  It only takes a Ted or Bob or a fire of some small part in the computer room to decimate your company.  Assume nothing!  Do you have the right employees doing the job?

Pray for our brothers and sisters in Puerto Rico, and if you have the ability, you might consider donating something to some of the excellent organizations who are working so hard to bring some relief to those affected.

Having lived through Alicia, I would not wish that on my worst enemy.

Ready, Fire …Aim

After the recent storms, one might have guessed that my phone has been busy.  Firstly let me say that Disaster Recovery by its very title is a bit of a misnomer.  While I have some abilities to recover lost data using some forensic skills developed over decades of twiddling bits, that is not really disaster recovery.

Disaster Recovery and business continuity are about planning for an event which may or may not happen.  The “plan” assumes that your business systems will be affected negatively and puts forth a tested strategy to recover from the said event.

With the recent devastation by hurricanes and earthquakes, one would think that those businesses not affected would be learning from those that were.  If you search my blogs on this site, you will see that I have laid out

Do not ask him or her, are we covered just in case, ask them specific questions laid out in this blog here.

Yes is not a satisfactory answer, demand the details and the proof.  I don’t care how much of a friend he or she is, demand the evidence.  The devil is in the details, and the last thing you want is a bunch of excuses.

I am learning from phone calls that too many have been assured that they are covered, and that is very possibly why today they are looking for ways to recover data from destroyed equipment.

Disaster recovery is not some dark magic spell cast under the voodoo magic of bits and bytes in the wiring closet or back part of the computer room.  The bottom line is to test it, whatever your people come up with, check it.  Keep checking it until you can recover your business with outside contractors and hardware with data and documents prepared by your staff.  There is to be no input from you or your staff during the test.  The hurricane, earthquake, fire, attack from zombies or employee error took you and them away from the scene. The plan provided must work!

This is why we who do this insist that companies use “best practice” standards in the industry when creating your individual networks and systems.

One such company has a senior IT staff littered with programmers.  These people think they know more than Microsoft.  Using kludges from Unix, Linux and other programming wizardry to subvert some of the basic tenants of networking, they have made their network so unique that it will depend on them to be there to recover.

If it is not broken, don’t fix it!

Writing programs that workaround things like DNS is just crazy stuff and now it is dependent on the network never changing, at all.

If your data is successfully mirrored offsite, an excellent team of engineers might get you going in weeks, not days if you have failed to follow best practices.  While your data might eventually be usable, you and your company will be on the sidelines as most businesses do not recover from such a catastrophe.

Folks I have been at this since 1982, I have learned a thing or two in those years.  Ask your team the questions or be prepared for unpleasant surprises should you ever face a business stopping event.

Got to go and explain once again what disaster recovery is and is not.

Are we cooking ourselves? Here is some food for thought.

Are we cooking ourselves? Here is some food for thought.

 

As a technology minded person, I often wondered about those who design cordless devices.  In particular, I am addressing phones.  I assume some government agency somewhere spent millions of your tax dollars to come up with what someone thinks are safe levels of radiation.

Maybe these people know more than the rest of us, or maybe they don’t.

Case in point.

The standard cordless phone in 2017 most probably transmits to the base either at 900 MHz or 2.4 GHz.  While your phone may advertise the higher frequency of 5.4 GHz that is most probably from the base to the phone.

Split frequency designs like this are prudent as it takes more power to transmit higher frequencies.

Now, these cell phones that we all carry around transmit either in the 850 MHz range or 1.8 ~1.9 GHz range.

MHz (Mega Hertz) stands for millions of cycles per second,  GHz is (Giga Hertz) or billions of cycles per second.  So every second depending upon the frequency, the RF (radio frequency) cycles millions or billions of time.  IE 2.4 GHz is 2 billion, four hundred million, cycles per second.

Frequency should not be confused or conflated with power.

Power for our conversation today is watts.  How much power or how many watts of RF (radio frequency) are we talking about?

Cell phones transmit up to 1.7 watts of power.

Cordless phones transmit as much and possibly more than a cell phone.  The interesting aspect of this is there is this DECT (Digital Enhanced Cordless Telecommunications) technology that has been around for a little while now.  They sell it as a plus but European studies have shown this might be more hazardous to your health than its predecessor.

The base of this technology is transmitting full power all the time whether your phone is in use or not. If the base is next to your bed or on your desk you are constantly bombarded with 5.4 GHz or at the least 2.4 GHz of radiated power in the form of RF.

Move it away from your body.

Why am I writing about this?

Ever since the first cell phones came out I wondered what they were doing and why.  These phones are always talking to the cell towers announcing their availability and telling them where they are while checking in.  The phone was and is smart enough to adjust its power level depending upon what is needed to communicate with the tower effectively.  The reasons are many but the main idea is to “talk” with one cell tower at a time.

My phone, even today will often time be warm in my pocket, or just sitting on the desk.

While we really have no idea what a smartphone is doing all the time, you can bet if it is warm, it is transmitting something.

I built this little device with a few diodes.  I will not belabor the technical aspects of this device other than to say it does not have any batteries.  These devices are passive in that the only way that they are energized would be by outside energy fields or EM (electromagnetic) forces.

I got the idea from the crystal radio of my youth.  Yes, I built one and housed it inside a pen casing.  With a single diode and a coil and very little know how I had a radio that would pick up local radio stations and never needed a battery.

Since my original device that I designed and built years ago, I found this version on the internet for a few dollars.

Setting this thing on top of my phone it soon became obvious that the cell phone is transmitting constantly.

  • Is it looking for data?
  • Is the phone talking to the tower?
  • Is the phone talking to my Wi-Fi network?

The answer is yes.  We really have no idea if the phone is doing anything else in the (tin foil hat category).

Now with 1.7 watts of RF at 2GHz, give or take, right next to your ear hole, one has to wonder if that is healthy.

Out of curiosity, I moved my device around the phone to discover that the most of the radiation or highest amounts come out of the phone right by the earpiece.  Why?

Knowing RF and the possible link to brain tumors, lymphoma and other nasty things why would the engineers put the transmitting antenna where it would be closest to your head?

This is the iPhone 6S.

My curiosity got the best of me so I checked my cordless phones.

IMG_4513

The light powered strictly by RF from the phone is very bright, right on the ear hole and down by the mouthpiece, the light, or power output is nonexistent.

IMG_4510

Imagine that your phone has enough RF power to illuminate an LED to full intensity and that energy is being pumped into your head right through your ear hole and of course next to your skull.

Tell me; why in the hell would you not put the antenna at the base of the phone where it would be furthest away from the body/brain?  The energy required to light the led dissipates with distance.  Logic would dictate that the less energy radiated close to your brain would be a good thing.

The pictures speak for themselves but now you know what you are looking at.

What can we do?

First off, we should ask the government for our money back that they paid for these studies.  One would think that if they can come up with SAR (specific absorption rate) and what is safe that just maybe they might have said, “you know, you phone makers should place the transmitter/antenna away from their brains.”

It is kind of like that commercial where the bank is being robbed and the guard says, “Oh I am not a guard, just a monitor… you are being robbed.”  What good is the FCC if they cannot think outside the box? The government, which they are part of, is to protect its citizens from faulty designs, much like the Corvair of the 60’s.  Where is Ralph Nader these days?

It is amazing to me that they did scientific studies to figure out how much tissue would cook or be damaged by rf.  Then they came up with the acronym SAR and finally did nothing more about it.  “Look for a phone with a low SAR rating.”  Are there labels, using this phone can cause brain cancer?”

What is so germane about 2.4 GHz and why am I sounding a little stressed about this?

That box in your kitchen that burns popcorn so nicely happens to work in that same frequency range.

Since there are millions of microwave ovens out there the FCC put broadband Wi-Fi, cordless phones, and many other unlicensed transmitters that the public uses in that same frequency range as the microwave oven.   Part of your license on each piece of equipment reads something to the effect that this device must accept and deal with  RFI or radiofrequency interference.

How does the microwave oven work and what does that have to do with my phone?

Microwave energy excites the molecules in stuff causing them to move faster.  Much like rubbing your hands together you get friction which causes heat.  That is how a microwave heats your lean cuisine dinner or left-overs from Sunday Brunch.  Yes it uses more power but I ask you, would you stick your head in your microwave to see how long it takes to fry your brains?  Consider the cell phone or cordless phone like a microwave crock pot, it might take longer but eventually, something is bound to be heated up.

Just for you people who think that I am a tin foil hat kind of person think of this one. 

How many of our urchins you call grade schoolers now have the very latest iPhone sticking out of the back pocket.  A trip to any mall will answer this question.  Even if it is a hand me down generation 5, it puts out all sorts of power right next to that thinner more malleable skull and younger more tender, still forming brain tissue.

Then there is this whole blood brain barrier thing that doctors talk about.  Does it really seem like a wise idea to put that kind of power that close to those newly formed brain cells?  They are future tax payers you know. Wink wink…

Possibly one of them will say, “someone should really put the transmitter in the base of this thing away from my brain.” Will it take a child to figure this out?  Maybe a riot on the Berkly campus to get the attention of corporate america who might tend to overlook such things.

I know, I am gettin my tin foil out… 

With telecommunications being a multi-trillion dollar industry it is no wonder that this is overlooked.  Much like the back scatter x-ray porn scanners at the airport which virtually strip search you, there is a greater good.  Bombarding our bodies with ionizing radiation is not harmful as long as the government says that it is ok. (sarcasm)

Calling attention to it might cost Nokia or Apple or Panasonic a few dollars.  What is the big deal about a few brain tumors, “can you hear me now?”

Since industry will probably not respond, how can you protect yourself?

Blue Tooth technology also uses RF in the same 2.4 GHz range but the power is very low.  A class one transmitter uses about 1mw or Millie Watt.  There is a newer headset that wraps around your neck with the earpiece extending from them.  That would put the blue tooth transceiver around your neck away from your brain.

Try to always use a headset or speakerphone, and if they still have them, a corded phone.

Use e-mail or text and by all means try talking to people face to face.  I know that is a radical concept but, I don’t think you are in danger of getting exposed to radiation that way.

About the device…

While the original crystal radio of my day used a 1N34 germanium diode this device uses nine 1SS86 diodes one tied to the other with an LED as one of the diodes.  The legs are purposefully left long like that as they act as the antenna to capture any energy that might be present.

If you are creative you could make it look like a bug with a tail and a head that glowed.  Just a thought.

I am not claiming to be an expert on any of this.  Just a person who thinks common sense is in limited supply.  These days we too readily accept that which is, without asking why.  Ask Why!

Cheers!
