New Encryption Minimums by June 2018
Transport Layer Security (TLS) is a cryptographic protocol that provides secure communications over the Internet. The initial release of TLS has known vulnerabilities and is no longer considered secure.
To ensure the security and integrity of email, most email hosts and servers will be requiring upgrades to the current version TLS. Google (the 800-lb gorilla in the email world) is also pushing for full sender authentication records in the Domain Name Servers (DNS). There are 2 records which verify the sender and one that tells the receiver what to do with any emails that fail either of the first two tests. To ensure you and your organization’s email continues to be delivered after June 2018, the following changes must be made:
- Sender Policy Framework (SPF) is an email authentication protocol allowing the owner of a domain to specify which mail servers they use to send mail. The receiving email server will check the SPF record against the server actually sending the email. If the sending server isn’t listed in that SPF record, the message fails SPF authentication, and may be rejected.
- DomainKeys Identified Mail (DKIM) allows an organization to take responsibility for transmitting a message in a way that can be verified by mailbox providers. This verification is made possible through cryptographic authentication.
- Domain-based Message Authentication, Reporting & Conformance (DMARC) verifies email is authenticated against DKIM and SPF standards, and that fraudulent activity is blocked.
All MintzIT business clients under contract will have their email servers and protocols upgraded between March 13 and April 30. You should not notice any interference with your email flow or other IT activity.
If MintzIT is not under contract with your organization, we can still perform this work for you.
It is estimated this work will take no more than 2 hours, and can be done remotely.
To schedule your email security upgrade, contact MintzIT at 888.479.0690×1.

PRACTICAL PARANOIA MACOS 10.13 UPDATE: ENCRYPT FOLDERS AND FILES FOR CROSS-PLATFORM USE WITH ZIP
Practical Paranoia macOS 10.13 Security Essentials has just released an update to chapter 17 Documents. The updated section is Encrypt Folders and Files for Cross-Platform Use With Zip.
macOS and Mac OS X have long included the ability to compress, archive, and encrypt documents folders in zip format. macOS 10.13 has removed the ability to encrypt these items in AES 256. As AES 256 is the gold-standard of encryption, we can’t just sit by and do nothing!
The section has been updated, removing the command-line instructions to encrypt zip, replacing it with using a free, drag-and-drop utility called Keka. Keka provides the easiest (and did I mention free) way to encrypt your documents and folders to military-grade standards. And since zip is an industry standard, your encrypted items may be used on Android, iOS, Windows, and macOS.
The updated chapter may be downloaded here.
