Hosts file for your protection

securityWith the recent rash of security concerns (across all platforms) I was looking into what can be done to route at least some of the nefarious traffic to the bit bucket. So I thought I’d write a brief post about the effort.

Most people are aware that DNS servers change the more user friendly internet addresses like yourbusiness.com to an IP address that computers can work with more effectively (e.g., 192.x.x.x). We can use this process to provide a bit more safety.

There are two simple ways you can try to subvert addresses pointing to bad locations. One is to use a domain name server that knows about bad services and provides a safe place to route the traffic.

IBM recently announced its quad 9 (9.9.9.9) DNS server. The Global Cyber Alliance (GCA) has partnered with IBM and Packet Clearing House to launch this free public DNS service. It intended to block traffic to domains associated with botnets, phishing attacks, and other malicious hosts. They continue to update it as new porly behaving addresses are discovered.

The other technique is to place entries in the hosts file on your machines. The hosts file actually gets a first shot at interpreting address. There are organizations that maintain HOSTs file that you can download, containing known ads servers, banner sites, sites that give tracking cookies, contain web bugs, or infect you with hijackers. Here are web sites for organizations that produce these hosts files:

Life hacker had an article about modifying your local hosts file, that is still valid and may be worth looking at if you’re thinking about adding this level of protection.

This all came to mind over the last few weeks, since Steve Gibson’s Security Now! podcast mentioned some new user tracking software that can be easily thwarted with a few hosts file entries.

Service Innovations over time…

SaaSI was in an exchange with Jim Spohrer (of IBM) the other day about Service innovations and he gave me the following lists dealing with service innovations:

Top Ten Service Innovations in all of History
1. Division of Labor – an entity gets to do more of what they do best, and less of what they do less well
2. Cities – local concentration of division of labor, including security and protection
3. Writing – allows communications over distance and time
4. Written Laws – brings more objectivity into governance and justice
5. Money – brings efficiency into exchange transactions
6. Universities – local concentration of division of knowledge, including preparation of next generation
7. Democracy – collective decision making via voting (citizen -> decision)
8. Republics – two stage collective decision making via voting (citizen -> representative -> decision)
9. Checks – safer than carrying paper money
10. Banks – safe storage of money, and compound interest/loans

Top Ten Service Innovations of Last 100 years

1. Universal Education – increases capability of population, and allows more complex problem solving
2. Universal Service – even rural people can communicate, and have right to communicate efficiently
3. Rural Electrification – even rural people can have lighting and access to modern appliances
4. Credit Cards – convenience and safety
5. Loyalty Programs – incentives for usage
6. Franchises – standard service in multiple places
7. FedEx – overnight package delivery
8. Automobile Transportation – systems of filling stations, roads, laws
9. Internet & Worldwide Web – access to information
10.  Wireless Communication Networks – Radio & Television – conquest of distance and access to service

Top Ten Service Innovations of Last 10 years
(or so)
1. Amazon – market for books and things
2. eBay – market for personal stuff
3. iTunes – market for music
4. Etsy – market for home made things
5. Uber – market for rides
6. AirBnB – market for rooms
7. Smart Phones & App Economy – access to information, communications, and other mobile services, including cognitive assistants
8. MOOCs – massively open on-line courses to augment education
9.  Mutual funds – finance investments that provide benefits of diverse portfolios
10. Global IT-enabled Outsourcing – division of labor between nations and large corporations

I’d add 3D printing to this list myself, but that may be just me.

Top Ten Service Innovations that broke out in 2014
1. TransferWise – lower transaction cost of transferring money
2. Coinbase – bitcoin digital wallet
3. Apple Pay – easier to pay money out
4. Lending Club – easier method to get investments in and out (founded in 2006)
5. Quirky – inventor community (started in 2009)
6. Bill.com – small business pay bills better (started in 2008)
7. Betterment.com (investment personal assistant)
8. Kickstarter – crowd funding (I think this actually started in 2009)
9.  Amazon Echo (home assistant)
10. Google Nest (home assistant) (actually the first Nest appears to be released in 2011)

Some things to think about…
What would be on your list? What should make the list for 2015? Do these innovations have anything in common?

When will 5G arrive?

Recently came across this interesting post on what 5G will mean for Consumers. In summary:5g wireless

  • Significantly faster data speeds: 10 Gbps, compared to one gigabit per second (max) with 4G.
  • Low latency (time to send a packet): one millisecond vs. 50 ms with 4G — great for those chatty applications being developed
  • The foundation for a more “connected world”: The Internet of Things (smart appliances, connected cars, wearables) will need a network that can accommodate billions of connected devices.

The most optimistic targets would see the first commercial network up and running by 2020, but even that may be too optimistic. As with LTE, it will take years for the network to become widespread.

What it will mean for businesses is the possibility for finer granularity across a wider geographic area. Hopefully, everyone is getting ready for IoT.

It does make me wonder about the future of relatively low speeds that many regions have as their entry level broad band for the consumer.
