The Internet Crime Wave
The Internet has facilitated the greatest organized crime wave since Prohibition (USA, 1920-33). Problematically, most cybercriminals and industrial spies are overseas, beyond the reach of law enforcement. Many are quietly supported by their national governments. For the foreseeable future, this crime wave will worsen.
One of the most devastating weapons in the cybercriminal’s arsenal is an Internet application which millions of us willingly use every day: email. It enables criminals to…
These vulnerabilities have forced the adoption of spam filters that inevitably bury legitimate messages, yet fail to block carefully crafted or targeted attacks. Spam filters may even help such attackers, as they create a false sense of security. In desperation, organizations have turned to proprietary SaaS messaging products, which lock them into a closed network built for the convenience of the vendor, not its customers.
SMTP, the protocol at the root of these problems, originated at a time when the links between Internet sites were slow and intermittent, and the only people using the Internet were friendly researchers in academia and government. SMTP cannot cope with the 21st Century, and must be phased out. See also SMTP will not be fixed.
Requirements for a TMTP Network
A. Multiple Members-only Services:
Every organization, whether tiny or enormous, needs a members-only messaging service that cannot receive traffic from external or unapproved senders.
Organizations that need to let certain members hear from the general public, or communicate with untrusted (perhaps anonymous) customers, may establish a separate service instance for that purpose.
Organizations may also join third party messaging services which allow membership for all involved in a specific field.
To prevent malicious correspondence (in the case of organizations with non-restrictive membership) messaging services must prevent members with whom you are not acquainted from sending you arbitrary content.
Messaging services must be able to control how members identify themselves to other members and prevent members from impersonating others.
To prevent theft of correspondence (in the event of a compromised account or server) the messaging service must store only messages that have not yet been delivered or returned as undeliverable.
Where archiving is required, the service should encrypt the traffic of designated accounts with a public key, and forward it to a write-only archive service.
The messaging service must support message distribution lists (aka groups) and online presence notification, as these are natural extensions of a messaging system.
For a small organization, the cost of the messaging service should be negligible.
B. Single Client Application:
Every individual needs a single messaging app that runs on virtually any computing device you own, and regularly connects to the messaging services of all the organizations you belong to, via a common network protocol.
The app should present a separate inbox for each service, and adjust the look of inbox & message views (e.g. fonts, colors, background graphics) according to the service’s skin settings, which you may revise.
The messaging services must reliably deliver every message to each of your devices that runs the app.
If one of those devices is discarded, lost, or stolen, you must be able to bar it from further access to your messaging accounts. A compromised device must not be able to hijack your accounts.
When you setup an additional device for messaging, the app must transfer your message history to the device in a peer-to-peer manner.
On receipt of a message, the app must not contact any third party Internet sites that the message might reference.
The app should provide a peer-to-peer method to let people in face-to-face contact exchange invitations to messaging services.
The app should enable encryption of your message history on local storage, and automatically backup the history to secondary local storage when available, e.g. a flash drive or microSD card.
For sensitive business data which must not transit a network unencrypted, the messaging app should allow encryption prior to send and decryption on receipt, using public or shared keys.
