How to Secure SMTP Email Delivery with TLS

Secure email sending is a priority for organizations that communicate sensitive data externally. One of the most common ways to send secure emails is with SMTP TLS. TLS stands for Transport Layer Security and is the successor of SSL (Secure Socket Layer). TLS is one of the standard ways that computers on the internet transmit information over an encrypted channel. In general, when one computer connects to another computer and uses TLS, the following happens:

  1. Computer A connects to Computer B (no security)
  2. Computer B says “Hello” (no security)
  3. Computer A says, “Let’s talk securely over TLS” (no security)
  4. Computers A and B agree on how to do this (secure)
  5. The rest of the conversation is encrypted (secure)

In particular:

  • The conversation is encrypted
  • Computer A can verify the identity of Computer B (by examining its SSL certificate, which is required for this dialog)
  • The conversation cannot be eavesdropped upon (without Computer A knowing)
  • A third party cannot modify the conversation
  • Third parties cannot inject other information into the conversation.

TLS and SSL help make the internet a more secure place. One popular way to use TLS is to secure SMTP to protect the transmission of email messages between servers.

LuxSci Provides Oracle Cloud Infrastructure Customers Secure High Volume Email Solution to Protect Healthcare Data

LuxSci Secure High Volume Email Sending is Powered by Oracle Cloud and Available on Oracle Cloud Marketplace

BOSTON, MA LuxSci, a HIPAA-compliant and HITRUST certified email service provider, and member of Oracle PartnerNetwork (OPN), is pleased to announce its Secure High Volume Email Sending solution has achieved Powered by Oracle Cloud Expertise and is now available on Oracle Cloud Marketplace, offering added value to Oracle Cloud customers.

Protected health information is highly valued by cybercriminals, which puts healthcare organizations at serious risk of ransomware and other cyberattacks. In 2020, 60% of all ransomware attacks targeted the healthcare industry. Oracle Cloud Infrastructure (OCI) is a deep and broad platform of public cloud services that enables customers to build and run a wide range of applications in a scalable, secure, highly available, and high-performance environment. OCI’s security-first design, encryption by default, and computing model proactively addresses common cybersecurity threats posed to the healthcare industry. Powered by Oracle Cloud, LuxSci provides highly secure and custom healthcare communications solutions for customers of all sizes.

“Our mission is to protect healthcare communications through highly secure solutions that are also highly flexible. OCI’s configuration options allow us to architect custom deployments for our customers that meet their unique security and compliance needs,” said Erik Kangas, CEO of LuxSci.

Before working with OCI, LuxSci used several public and private cloud providers, but they needed many customizations and upgrades to meet LuxSci’s stringent security standards. Combining OCI’s best-in-class cloud infrastructure with LuxSci’s best-in-class security solutions for healthcare communications creates a highly secure environment for any compliance need.

In addition to the security advantages of OCI, LuxSci has recorded measurable performance improvements to its systems, including memory that is 10 to 20 times faster than other public clouds and markedly improved CPU performance. These benefits are delivered directly to its customers, whose email and web services are speedier and more responsive.

“The cloud represents a huge opportunity for our partner community,” said David Hicks, vice-president, Worldwide ISV Cloud Business Development, Oracle. “LuxSci’s commitment to innovation and security with Oracle Cloud Infrastructure can help our mutual customers with cloud-enabled encrypted communications solutions designed for healthcare and compliance and ready to meet critical business needs.”

As ransomware threats increase, so does the demand for digital patient communication. Healthcare organizations must invest in the patient experience to keep patients satisfied and engaged in their healthcare journey. 60% of consumers expect their digital healthcare experience to mirror the consumer experience of retail. Healthcare organizations must adopt digital communication technology that is secure enough to send PHI and can engage patients at scale.

Together, Oracle and LuxSci are providing their customers with the highly secure environment needed for healthcare data. LuxSci Powered by Oracle Cloud enables secure, scalable, and reliable communications designed to meet the healthcare industry’s unique needs.

The Oracle Cloud Marketplace is a one-stop shop for Oracle customers seeking trusted business applications offering unique business solutions, including ones that extend Oracle Cloud Applications. Powered by Oracle Cloud Expertise recognizes OPN members with solutions that run on Oracle Cloud. For partners earning the Powered by Oracle Cloud Expertise, this achievement offers customers confidence that the partner’s application is supported by the Oracle Cloud Infrastructure SLA, enabling full access and control over their cloud infrastructure services as well as consistent performance.

How do I fix the reputation of my IP address?

It happens — you’re sending email messages without issue, and then suddenly emails are not being delivered, or they’re being flagged as spam. A little digging reveals that the problem is that your “IP reputation” is poor, and you need to fix it somehow.

AES-256 Maximal Security

Enhanced Security: AES-256 Encryption for SSL and TLS

AES-256 EncryptionSSL and TLS play critical roles in securing data transmission over the internet, and AES-256 is integral in their most secure configurations. The original standard was known as Secure Sockets Layer (SSL). Although it was replaced by Transport Layer Security (TLS), many in the industry still refer to TLS by its predecessor’s acronym. While TLS can be relied on for securing information at a high level—such as US Government TOP SECRET data—improper or outdated implementations of the standard may not provide much security.

Variations in which cipher is used in TLS impact how secure TLS ultimately is. Some ciphers are fast but insecure, while others are slower, require a greater amount of computational resources, and can provide a higher degree of security. Weaker ciphers—such as the early export-grade ciphers—still exist, but they should no longer be used.

The Advanced Encryption Standard (AES) is an encryption specification that succeeded the Data Encryption Standard (DES). AES was standardized in 2001 after a five-year review and is currently one of the most popular algorithms used in symmetric-key cryptography. It is often seen as the gold standard symmetric-key encryption technique, with many security-conscious organizations requiring employees to use AES-256 for all communications. It is also used prominently in TLS. (more…)
