ExtraHop Reveal(x) sheds light on the darkspace

Author: DCNN staff

ExtraHop announces Reveal(x) to be launched in summer 2018, which the company say is setting a new bar for Network Traffic Analytics at enterprise scale. The maker says its latest release includes new capabilities designed to modernise enterprise security operations with critical asset behaviour analysis that instantly surfaces the highest-risk threats, even those hiding within encrypted traffic. With this high-fidelity insight, ExtraHop has professed that security operations teams can zero in on critical threat patterns and investigate down to the root cause in seconds, not days.

Between 2017 and 2018, threat dwell time in the enterprise increased to 101 days, according to FireEye’s M-Trends 2018 Report. The Verizon Data Breach Investigations Report noted, ‘in many cases, it’s not even the organisation itself that spots the breach — it’s often a third party, like law enforcement or a partner. Worst of all, many breaches are spotted by customers.’

The company says its Reveal(x) release will significantly reduce dwell time by highlighting late stage attack activities, shining light on the ‘darkspace’ in the enterprise – the hard-to-reach areas of the network along the East-West corridor. Through comprehensive network traffic analytics, Reveal(x) is set to deliver real-time visibility and high-fidelity insight into threats to your critical assets throughout the hybrid enterprise. The new ‘headlines’ dashboard prioritises speed and accuracy, eliminating the fake news fire drills from other tools by highlighting the highest-risk detections correlated with external and industry threat intelligence. The company has announced that other key new features in the summer 2018 release include:

• TLS 1.3 support: As of 2017, 41% of cyber-attacks used encryption to evade detection, so the ability to detect threats within encrypted traffic is even more critical. With the latest release, Reveal(x) claims to be the only solution that offers out-of-band decryption at up to 100 Gbps and supports the requirements of the new TLS 1.3 protocol as well as decryption of perfect forward secrecy.
• Need-to-know decryption: Respect for privacy is simple now that authorised threat hunters and forensic investigators can be given rights to look inside suspicious packets for authoritative evidence (including content and user information), while other analysts only see the detections and metadata insights gleaned from the decrypted traffic.
• Network privilege escalation detection: Reveal(x) is said to identify changes to behaviour that indicate an attacker has compromised a device, escalated access rights, and is using these higher privileges to explore and attack within the enterprise. The company say that Reveal(x) now infers escalation attempts on critical assets automatically based on changes in device behaviour, commands, and protocol use, enabling detection of attacks underway and allowing SecOps teams to contain them before damage is done.
• Peer group anomaly detection: Reveal(x) claims to automatically correlate device behaviour against peer devices for more precise assessment of anomalous behaviour, leveraging auto-discovery and classification of critical assets. This strong outlier validation, the company says, improves insider threat and compromises host detection and enriches Reveal(x)’s investigative workflows with critical asset context that helps SecOps collaborate

“Today’s threat actors are taking advantage of vast attack surfaces that extend across every endpoint from the branch office to the datacentre or the cloud and too often they operate unnoticed,” says Jesse Rothstein, CTO and co-founder, ExtraHop. “At ExtraHop we’ve spent years developing technology that can analyse the entire network in real time – every critical asset and every transaction so that there are no blind spots. With Reveal(x) Summer 2018, we’ve applied that deep domain expertise to security operations, closing the visibility gap and surfacing the accurate, targeted information that allows SecOps teams to act quickly and with confidence.”
