Whitelisting vs. Blacklisting
- Jan 28, 2011 The new Mac App store has the same model as the iOS stores: To get your app in there it has to be signed by Apple. The next step is for the user to be able to say 'I only trust apps signed by Apple.' (This will be more difficult because the App Store business model (1/3 to Apple) will keep most prominent apps, like Office and Photoshop, out.
- The Find My app combines Find My iPhone and Find My Friends into a single app for iOS 13, iPadOS and macOS Catalina. If you need help finding it, use Search on your iPhone, iPad, or iPod touch, or use Spotlight on your Mac.You can also share locations or find missing devices on iCloud.com.
- Jul 10, 2017 Some people actually enjoy this sort of management on some level. But MAC address filtering provides no real boost to your Wi-Fi security, so you shouldn’t feel compelled to use it. Most people shouldn’t bother with MAC address filtering, and — if they do — should know it’s not really a security feature. Image Credit: nseika on Flickr.
The whitelist/blacklist debate is far older than computers, and it's instructive to recall what works where. Physical security works generally on a whitelist model: if you have a key, you can open the door; if you know the combination, you can open the lock. We do it this way not because it's easier -- although it is generally much easier to make a list of people who should be allowed through your office door than a list of people who shouldn't--but because it's a security system that can be implemented automatically, without people.
May 17, 2012 The report includes the top 10 apps that enterprises are blacklisting (or attempting to blacklist) in the United States and globally. The list is theirs. The snide commentary, mine. The official subreddit for all discussion or news related to the removal of setup.app on iOS devices without any stated purpose. The act of removing setup.app is no more than a filesystem modification made possible through jailbreaking, which is 100% legal under DMCA.
To find blacklists in the real world, you have to start looking at environments where almost everyone is allowed. Casinos are a good example: everyone can come in and gamble except those few specifically listed in the casino's black book or the more general Griffin book. Some retail stores have the same model -- a Google search on 'banned from Wal-Mart' results in 1.5 million hits, including Megan Fox -- although you have to wonder about enforcement. Does Wal-Mart have the same sort of security manpower as casinos?
National borders certainly have that kind of manpower, and Marcus is correct to point to passport control as a system with both a whitelist and a blacklist. There are people who are allowed in with minimal fuss, people who are summarily arrested with as minimal a fuss as possible, and people in the middle who receive some amount of fussing. Airport security works the same way: the no-fly list is a blacklist, and people with redress numbers are on the whitelist.
I have an old Belkin OmniView KVM switch which I used to use to share one keyboard, monitor and mouse between a few machines. Kvm software mac and pc. The Command key becomes the Windows key which can be annoying to muscle memory of copy/paste functions). However, I found later after I moved to DVI that it did support swapping the USB connector for the keyboard and mouse despite there being no VGA connections.I would imagine that if you're fine with the two separate monitors and thus the video connector doesn't matter, you could find an older KVM on craigslist/ebay fairly cheap and just use the keyboard/mouse switching.The only problem you'll run into is that the numeric keypad, Command, Alt Menu and Windows keys don't quite map the same between the platforms (e.g. Unfortunately, it was only for the older VGA connectors, not the newer DVI/DP/HDMI type.
Computer networks share characteristics with your office and Wal-Mart: sometimes you only want a few people to have access, and sometimes you want almost everybody to have access. And you see whitelists and blacklists at work in computer networks. Access control is whitelisting: if you know the password, or have the token or biometric, you get access. Antivirus is blacklisting: everything coming into your computer from the Internet is assumed to be safe unless it appears on a list of bad stuff. On computers, unlike the real world, it takes no extra manpower to implement a blacklist -- the software can do it largely for free.
Traditionally, execution control has been based on a blacklist. Computers are so complicated and applications so varied that it just doesn't make sense to limit users to a specific set of applications. The exception is constrained environments, such as computers in hotel lobbies and airline club lounges. On those, you're often limited to an Internet browser and a few common business applications.

Lately, we're seeing more whitelisting on closed computing platforms. The iPhone works on a whitelist: if you want a program to run on the phone, you need to get it approved by Apple and put in the iPhone store. Your Wii game machine works the same way. This is done primarily because the manufacturers want to control the economic environment, but it's being sold partly as a security measure. But in this case, more security equals less liberty; do you really want your computing options limited by Apple, Microsoft, Google, Facebook, or whoever controls the particular system you're using?
I can see it in the app on my phone, see it in the cloud, see it on kindle app on my mac, but it will not show up on my kindle.

Turns out that many people do. Apple's control over its apps hasn't seemed to hurt iPhone sales, and Facebook's control over its apps hasn't seemed to affect Facebook's user numbers. And honestly, quite a few of us would have had an easier time over the Christmas holidays if we could have implemented a whitelist on the computers of our less-technical relatives.
For these two reasons, I think the whitelist model will continue to make inroads into our general purpose computers. And those of us who want control over our own environments will fight back -- perhaps with a whitelist we maintain personally, but more probably with a blacklist.
