do u guys use anti virus?? if yes, which one?
if no, why no?
Is it virus free coz its based on linux?
I see absolutely no point in using antivirus on Android. I've sideloaded ton's of apk's from various websites and never ran into any problems. Pointless IMO.
Used it for about but also see no point of a anti virus on phones its those pesky advert that pop up in the status bar I want to completely stop

If you're not viewing dodgy sites and not downloading dodgy apps, there is no need. It is a waste of battery and resources imo
As the average new virus and the average 0-day is able to keep hidden for up to a year I see no point for anti virus at all! Heuristics almost never work correctly, and the number of possible security holes on a computer is so vast that it's unlikely they ever will :-\
Oh, and that time span is not my personal opinion, it stems from a study made by an employee from Norton Security (IIRC).
I've only installed avast for the anti-theft module.

Its not as though you have Terabytes of data to protect. At the most I imagine you would want to protect photos, sms/mms, music and perhaps app settings and highscores.
All of these can easily be backed up to a pc or cloud storage and its a good habit to get into because in my opinion flashing roms, radios ,kernels, hboots, etc has a much higher probability for data loss than a virus threat.
Ran lookout for a few weeks earlier in the year but have since binned it off. Ive never ran into any probems

Opinions differ. Tbh most antivirus use such a small amount of resources that I always think it's better to have it and not need it, than to need it and not have it. I use Dr Web Light. Works for me.
Officially I am done with google , as well as the other 7 companies caught up in this NSA mess. Anyone have a suggestion forms nongoogle based ROM for the nook color?

I am a researcher of bad deeds by corprocratic elites that run our world and if you didn't see this coming five years ago when folks like myself were shouting from the tree tops about these globalist controlled tracking devices then idk what to tell ya. If you are on the internet you have a link established with someone who is watching every move and unless you use an anonymous encrypted VPN to conceal everything you do and do not use social networking or any major search engine except startpage.com then the matrix already has you. And if you believe it is only the few companies named think again. A recent piece of legislation passed by the house and senate allows companies like telcos to get paid govt subsidies to forward information to these alphabet agencies AND more significantly removes any abilities you had to pursue a litigation based remedy against the companies doing this. And since it wasn't the govt spying on you directly, they now have an out for illegally collecting information on citizens. PS this was going on looooooong before the PATRIOT ACT was passed and this is the norm and not the exception. When SHTF economically here all too soon they will know who you are and who you may turn to for help. They will have completed their psychological profiling and prediction algorithms based on your past behavior and will know what you will do and when you will do it with stunning accuracy..
And if you scoff about this, you haven't done your research. Anybody remember that [open]BSD has those backdoors paid for by tax dollars? You think BSD is alone? Hahaha ..honestly in this day and age with the constant lies of the leadership laid bare at our feet you would have to be crazy NOT to realize these things and seek out their own words..

Most roms available are based on android, and only a few demo operating systems have been created that are not based on android for the Nook Color.
The Ubuntu Touch demo works for the most part.
Someone got open WebOS working on the Nook Color, but it might take a while to get it working on your part.
You could always port over your own OS if you are that desperate.
If you really want a kinda non google rom and that works well I would have to suggest the original rom that came with the Nook. Even though it is still running android it was modified by Barnes and Noble and is different than the android interface.
Ideally I'd love to see something with ghosting built in. The main reason I want to distance myself from android is to avoid the data mining/forwarding issue

I work on a project designed to compromise the data collection. Look up OpenPdroid and the auto-patcher. All system and app calls for data will still go through, but you will be able to either block or spoof the data returned.
Installation is not exactly trivial...we are working on that.
It's not a perfect solution, but ChameleonOS has a built in Permissions Manager in which you can control your apps.

From the posts I think many are not realizing that the spy features are BUILT IN TO THE CORE apps and frameworks of the OS especially where proprietary gapps are included. You could disable certain features but then it also wouldn't function properly for your own purposes. And if it is based on android it probably is riddled with the same issues.

Dump Google Apps / Get OpenPDroid ... Use ixquick Search Engine
I'm running CM 10.1 but I don't install Google Apps which makes a huge difference! GApps is the most invasive, nosiest app I have ever seen! Without that on your tablet you do not have to register the device or provide any info at all... no "setup"... Then I use pandaapps.com and other alternative app sites/ways to get apps. Right after flashing a ROM I also disable all location/GPS crap and go into the browser settings and do the same before enabling wifi. Then I make ixquick.com the search engine. On top of that I am working on installing OpenPDroid but it's not the easiest thing to do yet... the auto-patcher that works in Windows to compile the ROM and PDroid patches doesn't work with every ROM. But OpenPDroid will allow you to control what info and access apps get, by (for example) setting PDroid to give the app null, fake, or random data in place of real data. It's still not perfect but it's a lot better....

After reading the article, I'm glad I'm not the only one who's experiencing this issue. I've noticed my Nexus 7 slows down and becomes less responsive during heavy writing task(downloading stuff at high speed, stuttering browser, etc).
Before anybody jumping in and saying they don't have the issue, the point is it does happen and it happens to other devices as well. Same issue can be said for Galaxy Nexus, Asus Transformer Infinite Transformer Prime. A good way to test this is to see how your tablet performs when you download something over 1MB/s or 2MB/s.
The reasons some people don't see this are:
1. It's hard to tell in short term. Usually the memory i/o speed degrading starts to show after 6 months to 1 year or longer depending on the quality of the flash memory they use.
2. Interfering factors. Many people think the lag is caused by ROM or kernel. It could be true in some cases.
3. Inconsistent quality control during manufacture. I'd assume that out of some bad batches, there will be also some good units. Also not every device use the exact same flash memory chips.
4. Personal usage difference. Flash memory's life span depends on the limited number of writing/reading. So the degrading rate also depends on each individual. Some people are heavy users who constantly perform copying/reading/removing actions on the device while some others may only use it for internet access which results in less taxing work.
Actually the i/o speed issue is one main reason I'm looking forward to next generation Nexus 7. Just hope ASUS can use better quality flash memory next time.
EDIT: more elaborate point.

I don't know, if Asus doesn't get it right on 2 devices, all of which I have owned, I can't imagine that they will get it right on the next 2 devices. I was so tired of my laggy infinity that I just sold it on ebay. I was so tired of my laggy nexus 7 that I did a factory reset. But then again, these were essentially first generation products. Hopefully the second gen will be better (seems to contradict what I just said, haha.) I am probably going to wait for a little while before I get the next nexus, anyway. I have an expensive habit of getting the latest on launch, most of the time regretting my decisions.
I haven't seen any of the lag these sites and users complain about. Maybe its because I was more used to my Iconia A500 dragging its feet at the two year mark but I can't see how this is "laggy" or "unresponsive" at all. I think this is the result of seeing the device as "old" rather than "new" so you notice one thing and look for 100 others you never noticed. In the end though it could be worse. You could've paid a pretty penny for it to turn to crap All I can say is that I have not noticed these problems and that if they remain after a wipe and reversion to an older, version then they must have always been there.
Its flash storage over all devices. I've seen the same lag on my wifes ipad and iphone.

Well, the thing is the performance drop is very distinct and easy to see. When the device comes to a stall during some background writing/reading, then it's problem.
The reason some people don't see this is:
1. It's hard to tell in short term. Usually the memory i/o speed degrading starts to show after 6 months to 1 year or longer.

Every computer I have ever used - that's over a 30-year period - could have its' UI brought to it's knees with heavy I/O. It's not a surprise, really: mass storage is typically the slowest bandwidth device (ignoring things like uarts or keyboards) in the system.
The problem can be pushed into a corner - for instance using massively more RAM than is needed by the memory footprint of the kernel and apps, so that there is plenty of fast file cache available, but even in that case, a source of sustained high-speed I/O will eventually exhaust the write cache, and slow writes will start occurring and queuing up against all other I/O activity.
But that kind of thing doesn't happen in a $200 tablet. RAM ain't cheap, nor does it come for free in terms of power consumption (and thus battery size needed for a given "on battery" time).
On top of that, you have all the problems of write amplification that occurs with flash memory that performs block erasures and wear-leveling.
IMO, if you think this is something that only occurs on certain OS releases, or certain hardware, you are probably going to be disappointed with every device you ever buy. That will be the case until a non-volatile storage media exists with sustained read/write bandwidth that exceeds that of the system memory bus, and also is not affected by the number of independent transactions per GB of I/O.
BTW, the fact that someone on the internet complains about a problem with symptoms similar to those you experience does not imply that the same root cause is involved, nor does it say anything about the frequency of occurrence of those symptoms amongst the general population. I suppose that some small percentage of the world's population is tired all the time; but that doesn't mean they all have Lyme disease, nor that everybody has it.

Gruber linked to it. Joy. Prepare for this article to be linked to by every iOS fanboy from now until the end of time.
My theory is that its mostly prevalent on the 8 GB models that were only sold for a short period of time, and thats why only a few people, mostly early adopters, have seen this.
I torrent ... "things" ... at over 1.5 MB/sec.
Don't see a dip in speed at all. Try changing your IO schedulers, people.
Mine gets slow when I have less than 3gb of storage open.. Above that, it is fast. It's not a permanent problem. Try freeing up space before damning the Nexus 7.

The N4 has twice as much RAM as the N7. See my comment about file write caching above. It is quite reasonable to expect the N4 to perform better under equivalent load as there will be substantially larger free memory for write caching (everything else being equal). Simply put the N7 will hit the I/O queue wait wall first.
A statement from one or two users that "my tablet doesn't do that, what are you talking about" is just as relevant information as one or two users claiming "my tablet is always slow".
Neither report is a denial of the experiences of others; but both taken together are a demonstration that the trouble described is not universally experienced.
And since neither set of onesie-twosie reports represent a statistically significant sample, neither of them are capable of saying anything meaningful about how widespread the problem is in the general user population.

I'd also be surprised if most Nexus 4s have had the same amount of wear on them as the Nexus 7s. Just saying.
Your I/O scheduler definitely helps, but unfortunately software fixes can only play catch-up for so long. It's one of the things I really do dislike about flash memory-- yes, I know that spinning disk media also has wear, but I've had some drives running for...practically forever, really. I just don't feel comfortable knowing that SSDs and flash will eventually cop out because of how they're designed (but a lot of that, I'll plainly admit is a psychological thing and has little to do with the tech's actual reliability).

Your right when I wake my n7 from sleep with no apps updating or anything running, and it moves at a ants pace. I am wrong its me I guess...right. Every user should have to unlock root and flash a kernel to change how it runs.
I read the comment you made before, its the same copy pasta stuff from when the nexus 7 didn't have issues having the storage full, back early on. This what makes xda so great, people have a issue and someone chimes in tells them they are wrong, or ten posts of "420 root it, and flash mer devs kernel"
But your right my tablet should mostly be lagging because running the launcher and maybe an app slows everything down because its designed to run an app and that's it.

If that happens on a stock device with no apps that's been rebooted within the past few days, and there are no other pathologies involved (e.g. nearly-full or corrupted file systems), then *probably* there is a hardware problem involved.
Look, I get it. Plenty of folks just want to use their device, not worry about details, and have it work as if it were mint. And they want it to behave that way even after customization (adding random apps). But practical experience with a wide variety of computing devices reveals that performance problems always hinge on details - sometimes incredibly tiny and obscure details. Those "details" can be any number of things - "soft" (correctable) hardware defects, bugs in the OS software, user software that is installed, all sorts of stuff. And even for technically sophisticated users isolating the root cause can be difficult. Until some detective work has occurred, there is no justification to place the blame on any specific component.
BTW, I know how frustrating it can be. My old Android phone (rooted, OC'ed & CM 7 ROM) currently can not be operated with both the messaging app and launcher app locked in memory (It only has 190 MB of RAM!). So I get to choose between losing text messages or waiting 15 seconds !!! for the launcher app to repaint the first home screen after leaving a resource-hungry foreground app such as Maps or the Browser. If I try and set up the Android LMK to do aggressive memory reclaim, the device will occasionally enter a "thrash of death" where the LMK is killing off threads as fast as they are generated - and the whole device will go frozen for minutes at a time. So, yeah, I get the frustration.
That of course is indeed "my fault". I could go back to a factory stock ROM (Eclair w/ HTC Sense - ugh). But I don't want to. I want certain features, and I want certain apps, too. You might claim that's not comparable to a user having a stock ROM device with a whole bunch of market apps installed; but until those apps can be cleared of suspicion, blame cannot conclusively be laid anywhere.
It is what it is. Computers that do not exhibit load dependent performance problems do not exist. That doesn't make things anybody's "fault" - but it is highly unlikely that Google (or Apple, whomever) is going to send someone over to your house to figure out what goes on with your tablet.
So, moaning about a problem on the internet might make someone feel better for a few minutes, but at the end of those few minutes, the problem(s) will still be there.
And BTW I completely get it that if I were to be having a performance issue on my tablet, and I wanted to clear my 72 market apps from suspicion, it would take me as many as log2(72) ~= 7 binary bisection trials (remove half of apps each trial) to finger a suspect or clear them all from suspicion). Pain in the rear to be sure; but it wouldn't be any less work on a different device - Apple, Asus, HTC, Moto, Samsung, whatever. And if it were an intermittent problem? It might take a huge effort to isolate the cause. Way longer amounts of time than simply ignoring a second or two of hesitation in the UI.
But the OP created this thread in the General section, not the Help / Q & A section; was he even interested in getting help?

Encryption will only protect your data from someone who has got physical access to your phone. Nothing else.
When you boot and enter the password, it allows android to read the data. If you copy data off in this state, it is decrypted as it moves to another device...
If you don't have the password and somehow physically get access to the data partition, as you copy data off, it remains encrypted and cannot be read by anyone.
You are not protected from "hackers". If someone has managed to get access to your phone remotely by whatever methods (you installing warez for example) you've already booted your phone up and allowed android to read the data so you can't stop "hackers"
So the advantage is if you lose your phone, no one will be able to laugh at the pictures you took naked, in front of a mirror.
Thanked you, so it's useless unless someone wanted data off my phone and my phone was switched off when they wanted the data? Google and Motorola are slowing my phone down for THAT???

No your phone can be on, so long as your screen is locked. But only protecting from people with physical access. There would be no real way to safeguard from remote attack, however that would be extremely unlikely anyway.
The encryption is so that they can compete better in the corporate world with IPhones. May not help you, but people with corporate information on their devices may have more concerns about their data.

your phones(nexus 6) isnt slowed down, thats a misconception that most people think is happening(because someone else said so) but really isnt. the read/write speeds get slowed down slightly, to about nexus 5 levels. but the phone, and its performance, isnt really affected.
Try not to focus on protecting your embarrassing nudies and think more along the lines of having other personal information or banking information and your phone gets stolen. A thief could potentially steal this info for other purposes.

Protecting nude selfies are exactly why it's encrypted! Lol..
Well maybe not if you also upload them to google drive.
Like everyone said, it's to protect the data on it, whatever it might be.
The police and NSA I think would have a hard time accessing it without your password.
If it's something like a rootkit that monitors your usage though, it doesn't prevent that.
I think it's worth it but I don't do a lot of writing; which is typically the slowest link in the chain.
Real world encryption example:
Your username/passwords on anything website related is stored in a database (most likely SQL). When your inputting your username/password it's being checked into the database to see if the combination is correct or not correct. This is usually passed through a TLS/SSL protocol to protect the passageway of your information.
If a hacker was to obtain the database on the servers, the hacker would have to go through a decryption process which would take considerable amounts of time to decrypt the data. It is possible for the hacker to decrypt the data but it will take a long time. If this was not encrypted, a easy example would be that the combination of username/password would be stored in plaintext.
Plaintext: thisismypassword
Encrypted: !KA4IU5NBAK (random characters)
You can read about encryption on wikipedia. A fairly simple cryptosystem is RSA.

As has been said, it protects data from physical access. Especially in the US, where encryption, whether it is "good" or not, provides you with a LEGAL protection against snooping. I.e., any data recovered by law enforcement from an encrypted device is inadmissible, EXCEPT if you VOLUNTARILY yielded your passcode.
Further, it protects your data from anyone who gets their hands on your phone, like a thief. This is particularly important for business use, where there could be sensitive data stored on the device, if someone steals your phone, you don't want that person to gain access to all the sensitive information on it.
For "average joe", the benefit is protection against law enforcement. And don't give me that crock about "if you have nothing to hide" -- the reason why certain things are classified as *rights* is because you DON'T NEED ANY JUSTIFICATION to exercise them.
The reason why anyone else benefits, is because it protects sensitive information from unauthorized access.
As far as protection from online thieves.... well that's what selinux does. Nexus 6 ships with selinux set to enforcing. It is also what *common sense* does. Don't even consider installing "hot girls" application from China that asks for network, contact, storage, messaging access, because its purpose is to send your sensitive information to those who have no right to it.

your phones(nexus 6) isnt slowed down, thats a misconception that most people think is happening(because someone else said so) but really isnt. the read/write speeds get slowed down slightly, to about nexus 5 levels. but the phone, and its performance, isnt really affected.

Encryption causes a MASSIVE and VERY EASILY measured reduction in I/O performance;

Take a look at the hit against sequential read.... 131.65 MB/s without encryption, 25.36 with. That difference is enormous.

As has been said, it protects data from physical access. Especially in the US, where encryption, whether it is "good" or not, provides you with a LEGAL protection against snooping. I.e., any data recovered by law enforcement from an encrypted device is inadmissible, EXCEPT if you VOLUNTARILY yielded your passcode.
Further, it protects your data from anyone who gets their hands on your phone, like a thief. This is particularly important for business use, where there could be sensitive data stored on the device, if someone steals your phone, you don't want that person to gain access to all the sensitive information on it.
For "average joe", the benefit is protection against law enforcement. And don't give me that crock about "if you have nothing to hide" -- the reason why certain things are classified as *rights* is because you DON'T NEED ANY JUSTIFICATION to exercise them.

Thanks : knowing that the police and other organisations cannot access my private data as they have done before, despite having ZERO grounds for believing me to be involved in criminal activity (as I am not lol) and having had all assumed consent withdrawn, makes the performance hit worth it.
And yes I do notice the slowdown myself, it isn't too much to bear though.
What other phones are encrypted as standard? Are the latest iOS devices, the latest windows phone lumia devices, etc or any other Android devices encrypted as standard like the Nexus 6?

problem with that is all dependent on what app you test it with. with some benchmarks the difference is huge, with others its much less. which is right? anyways, i do not use a computer, and do not transfer files to one, ever. so i dont see this lowered read/write, so i can say it barely affects me. and again, as i said before, it does affect read/right, but besides that it does not affect the performance of the phone itself.
Coming from a nexus 4 on L I notice the speed difference : once an app is open and running it's faster, the power difference is obvious, but launching apps, certain UI elements, initial boot up, opening pictures and media etc is all much slower on this beast than it was on the Nexus 4 (not even talking nexus 5). It's not a deal breaker and obviously can be disabled for those who want it.

i own the n4, n5, and n6. open and starting apps is not slower on the n6. if yours is slower, either there is something wrong with your device, or its your setup.
I've noticed that the phone is much faster and more stable (as are touchwiz phones) when you uninstall Facebook and Fb messenger apps. I know it's not related specifically but I recommend it. Life is better without Facebook

Actually I too as well see lag issue of a sec or 2 when opening apps. Once they are open they fly but when i initially open them it lags and same goes with media as well. YOU can really tell when using the recent apps drawer/menu. Think i will flash f2fs twrp and decrypt my phone and see if that makes a difference.
I hope google find a way to optimise the process a little more in future updates, I really wanna feel that 805 processor!

Verifiable with dd.
dd does not lie.
So... My N6 is encrypted but I don't get prompted for a pin or password when I boot. So what does this do for me? Nothing but mess up my performance?
I'm debating buying a Chinese Cyanogenmod phone. That got me thinking about security. People have different ways of dealing with it. I tend to prefer trying to keep my main phone secure. If you have an unrooted iPhone do you prefer to do banking on that? Or a linux laptop? Or a blackberry? Or do you keep one phone particularly clean for this kind of thing?
Lets say you have a file worth $50,000 and you had to store it on a phone, what would you choose and why?
Hoping for a fun but heated civilised discussion, though one word answers are welcome :good:
Windows Phone. Apart from fact I love it anyway, no one cares about it, and you look more inconspicuous than if you had a BlackBerry. Bonus points if its also one of the last Nokia's, as it can be uses as a weapon in a pinch.

No system is secure.
All devices can be hacked.
For a 50,000$ file , an elaborate storage transfer can be executed ...I won't be using any phone to transfer it ...
A 50.000 quid file? I'd happily store it on my Note 3. Nobody expects an artist to carry a file lile that on a regular phone, I don't leave my phone anywhere, never hand it over, and I always have all connections off unless I'm using it. (I'm a bit ocd when it comes to batterylife.) And I always do my banking on it, just never over open/public wifi points.
And I'd disguise it as something else. I've had to deal with documents that required a confidentiality agreement, and my best method is renaming the entire file, including the extension, into something inconspicuous.
Nameless64.png (or .psd for a big file) is not going to stand out amongst the other 8900 nameless files in my 450 'New Folder's. (Yes, I'm hopeless at file management.)

This is true, that's why both shadowlea and I suggested looking inconspicuous instead of having the best file security. I personally chose windows phone because your less likely to be found on a random hacking attempt, as not enough people one to make hacking it worthwhile.
Definitely renaming it and changing the file extension should be done also.

And if you want to be really, really thorough, zip it, rar the zip, then zip it again, then rename it to a jpg or pdf or psd. (Or whatever is most likely to be on your system. PSD makes sense for a designer, but not for an engineer.).
That way they can't locate the file by scanning the device, as the code's changed as well. And double compress it, because you can't scan a compressed file inside a compressed file.
And yes, I have put far too much thought into this. :silly:
I would create and app to store that file, so the file is protected by Android permissions.
No, really, the best way is to encrypt it with a password or a password-protected key. In that case, no matter who has the file, only who knows the password can decrypt it and access the data.

I agree. Use es file explorer to encrypt. Select the option to encrypt file name and then the name of the file is just a string of numbers. Store that in a sub file of the android system, and everyone will just think its another system file.
Too much trouble but you could also store the encrypted file in the root directory, then unroot the phone.

It works against common folks.
Against any professional worth his salt ,these techniques are pretty much worthless. On the contrary you are helping the professional by filtering the file from the rest
. Any Professional is adept to work with 100K' s of files per request so obfuscation by numbers or type is pretty much pointless.
Encryption works fine. Except for a small part. Data is destroyed if key is destroyed and in such scenario the value of 50K file is worthless.
Any open system is easily hackable or accessible. To secure 50K worth data on a continuous basis ,you are better off using a prop. system whose standards are known to limited set of people. It filters out most common attacks .
Of course every system fails in front of a pipe wrench

Technically speaking, any selfrespecting professional would put the file on a storage medium that isn't connected to anything. A microSD folded inside a piece of aluminium foil is pretty much steal-proof.
Well, digitally speaking, anyway. No encryption or software is going to protect you from someone who hits you on the head with a blunt object and physically steals the storage device. And they don't work all that well against guns, either.

If you trip KNOX, the KNOX container is destroyed. So if you intend to use it, you can't trip it to 0x1.
Also, if you had any files inside the container when you tripped the fuse, they're wiped as well.
Try to really imagine that you're in that situation where you must use a phone. No dodging the question by using offline storage!
How would you actually feel about it?
Personally I would feel nervous about it because by law only devices with closed source modem code are allowed to connect to phone networks. In turn we have seen this as a backdoor that allows access to the phone. And we have then seen the likes of the NSA using this to access our phones.
So there is no phone out there that isn't back doored.
But... some have more protection than others and to all intents and purposes is someone at the NSA going to bother with $50k?
I don't know. This is half the point of this question. I am curious to see how other people react in the situation. Because there are a whole range of threats. The question becomes - what level should we protect to? Certainly that dodgy flashlight app. But also we have seen the FBI steal Bit coin funds during investigation so I would argue that this could be a realistic aim to think about. But then probably the FBI aren't going to be looking through your phone - who knows.
The point is to view things from others viewpoint to try to learn something.. In particular I was hoping to see points of views from different countries where spare is more common. For example in China we have a different kind of insecurity. Something that might have been discussed and discovered as a result of this hypotetical thought game might have been that a Chinese phone is or isn't easier to lock down than a USA one.
now you're going to look at my paranoid post instead of coming up with your own responses... which could just have been to stick it on a factory stock phone and not worry.
But that's also something I'm interested in. We all lead different lives. So I wonder if it's easier for others to deal with. The example.of an artist above is a good one. Really imagine you have that file, and it must be on a phone

Use phone in offline mode as storage, Or use a smartphone. adb perma locked , fastboot locked, Internet routed via private server with a whitelist to filter the network.
That will protect you against online intrusion,
A pickpocket can steal your phone and make a mockery of your security measures ...
Government officials can take you into custody and get the data from you.
Cyber warfare and security is over rated beyond feasible limits.
You are more likely to get mugged than hacked.
