How Does MTA-STS Improve Your Email Security?

30 August 2021 at 11:54
Simple Mail Transfer Protocol or SMTP has easily exploitable security loopholes. Email routing protocols were designed in a time when cryptographic technology was at a nascent stage (e.g., the de-facto protocol for email transfer, SMTP, is nearly 40 years old now), and therefore security was not an important consideration.  As a result, in most email systems encryption is still opportunistic,

New Microsoft Exchange 'ProxyToken' Flaw Lets Attackers Reconfigure Mailboxes

31 August 2021 at 03:27
Details have emerged about a now-patched security vulnerability impacting Microsoft Exchange Server that could be weaponized by an unauthenticated attacker to modify server configurations, thus leading to the disclosure of Personally Identifiable Information (PII).

Researchers Propose Machine Learning-based Bluetooth Authentication Scheme

31 August 2021 at 13:00
A group of academics has proposed a machine learning approach that uses authentic interactions between devices in Bluetooth networks as a foundation to handle device-to-device authentication reliably. Called "Verification of Interaction Authenticity" (aka VIA), the recurring authentication scheme aims to solve the problem of passive, continuous authentication and automatic deauthentication once

[LIVE WEBINAR] How Lean Security Teams Can Improve Their Time to Response

1 September 2021 at 12:50
Cybersecurity could be described as a marathon for security teams that spend most of their time building sustained defenses that prevent threats day after day. However, they must be ready to hit a sprint whenever an attack succeeds since attack duration, and the resulting damages are directly correlated.  Reacting to a successful attack is a major challenge for lean security teams today since
