What’s new: Microsoft Sentinel Deception Solution – Among the most successful and well used techniques the adversary has in their toolbox is an attack which involves some form of deception, knowing full well the human vulnerability and ease of which it can be exploited. Whether it’s social engineering or spear phishing, deception plays a major part in most cyber-attacks impacting our customers today. But deception is a two-way street and defenders can use it to their advantage. By planting decoy resources in strategic locations and with heightened monitoring, defenders can lure an attacker in, forcing them to reveal their presence when they would otherwise remain undetected.

It’s not all about the data! Protecting Your Users in Teams with Communications Compliance – As administrators if we don’t know or have line of sight of the apps our users are using; or have any idea if malicious actors are already inside of our network; if we cannot control our own data from insider threats it begs the question – what else are we missing? Are we aware of – or do we have any control over – our users’ devices? Do we drive their servicing to ensure they are current and have the latest protection? Are we thinking about concepts such as Zero Trust or Conditional Access or AI driven security? Investing in Passwordless? Do we know what a SIEM is? What MITRE attack is? And do we have any oversight of regulatory or code of conduct violations through the apps we use like Exchange, Yammer, and Microsoft Teams?
