Roundtable roundup from the European Information Security Summit

Posted by Matt Walmsley on Feb 23, 2017 8:23:53 AM

Earlier this  week  I was at TEISS hosting a round table session titled “Artificial Intelligence – Fancy maths or a pragmatic answer to cyber security gaps and challenges?”

We explored human, threat, and technical dimensions to the current drivers and role of AI in cybersecurity. Here's a summary of our group's discussion.

Encrypt everything. Don’t let security be the reason you don’t (and attackers do)

Posted by Chris Morales on Dec 15, 2016 9:32:58 AM

On the cybersecurity website ThirdCertainty.com, Byron Acohido makes some very important points about the use of encryption by hackers to avoid detection tools and the need to detect these attacks. This is a water cooler discussion at Vectra headquarters. Encrypted traffic is an easy hiding place for attackers and difficult for organizations to deal with. 

However, trying to monitor this traffic by decrypting first, performing deep-packet inspection, and then encrypting again at line-rate speeds is problematic, even with dedicated SSL decryption, especially in the long term. There are several factors at play here. 

With an increasing global desire for privacy, more traffic is encrypted by default. It is becoming a standard for cloud applications. The Sandvine Internet Phenomena Report states that encryption doubled last year in North America.

This is actually great news, especially for consumer privacy. Enterprises have a strategy to encrypt everything. With this encryption however, attempts to perform SSL decryption mean there will be large volumes of encrypted data to process.

Cybersecurity: What to expect in 2017

Posted by Hitesh Sheth on Dec 13, 2016 5:00:00 AM

Cybersecurity is a rapidly evolving landscape and 2017 will be no different. Attackers will leverage artificial intelligence and find new ways to infiltrate corporate networks and businesses using adaptive attacks. Encrypted traffic will increasingly blind legacy security technologies, while ransomware gets smarter, and more targeted. Also watch for geo-political changes that act as a catalyst for increased cyber attacks involving nation states.

Ransomware, encryption and machine learning – Three key takeaways from Infosecurity 2016

Ransomware, encryption and machine learning – Three key takeaways from Infosecurity 2016

Last week was a long one. Vectra participated for the first time at Infosecurity Europe in London. Now that my feet have recovered from our very busy booth I thought I shared a few of the recurring themes I noticed at the show.

Ransomware. Definitely the threat de rigueur with vendors coming at the problem from various angles, including DNS management and client based solutions. Vectra was part of the buzz too, offering a network-centric approach with our newly announced ransomware file activity detection.
