Security researchers announced this week that they had discovered a significant vulnerability in almost every computer on the planet. This vulnerability – actually two related ones called Meltdown and Spectre – allow a malicious application running on a computer to peek into the memory of another application on the same computer and suck out its contents. This is most devastating in public cloud environments where applications from different customers often end up running on the same physical computer.

Defending Against The $5B Cybersecurity Threat – Business Email Compromise
If an average employee at your company got an email from an executive with an urgent request, would they question whether the email was coming from the actual sender? They probably wouldn’t. The reality is that most people would act on the request because of its time-sensitive nature. They assume that the IT team has the right technology in place to validate email senders so they can focus on doing their work. But this is why attackers succeed. Their target thinks the email is coming from someone they trust and consequently, their organization gets breached. This type of attack is called Business Email Compromise (BEC), email spoofing or spoof abuse. The FBI estimates it has cost companies $5.3B globally – far more than the $1B in 2016 for ransomware.

Cisco UCS Automation Series, Part I – Getting Started with UCS PowerTool
You WANT to Automate! But Where to Start?

A lot of questions typically bog down the process, mire you in indecision and eventually you give up!

Introducing executive dashboards in CTA
No security risk assessment is complete without the executive summary section. Something that can answer the high level questions security teams get asked including “how secure are we?”, “what threats are affecting our network today?” and “how healthy is our network?” We have recently revamped the Cognitive Threat Analytics dashboard to provide answers to these questions and more.
