Aruba modernises network security

Aruba, a Hewlett Packard Enterprise company, has announced the Aruba 360 Secure Fabric, a security framework that provides 360 degrees of analytics-driven attack detection and response to help organisations reduce risk in a changing threat landscape.
Aruba is also innovating in User and Entity Behavioural Analytics (UEBA) by expanding the Aruba IntroSpect product family, enabling businesses to easily and rapidly scale machine-learned behaviour detection from small projects to full enterprise deployments.
Gartner’s research into insider threats indicates that organisations are not adequately considering the risk from their trusted users even though there are myriad examples where organisations have been impacted. On a positive note, Gartner fielded almost a 100% increase from clients looking to address the insider threat issue, of which UEBA is one of the primary technologies.
To help organisations address new and unknown threats, the Aruba 360 Secure Fabric offers security and IT teams an integrated way to quickly detect and respond to advanced cyberattacks from pre-authorisation to post-authorisation across multi-vendor infrastructures, supporting enterprises of all sizes.
Components of the Aruba 360 Secure Fabric include the following:
* Aruba IntroSpect UEBA solution: A new network-agnostic family of continuous monitoring and advanced attack detection software. Includes a new entry-level edition and uses machine learning to detect changes in user and device behaviour that can indicate attacks that have evaded traditional security defences. Machine-learning algorithms generate a Risk Score based on the severity of an attack to speed up incident investigations for security teams.
* Aruba ClearPass: A proven network access control (NAC) and policy management security solution that can profile BYOD and IoT users and devices, enabling automated attack response, is now integrated with Aruba IntroSpect. ClearPass can also be deployed on any vendor’s network.
* Aruba Secure Core: Essential security capabilities embedded in the foundation across all of Aruba’s Wi-Fi access points, wireless controllers, and switches, including the recently introduced Aruba 8400 campus core and aggregation switch.
Aruba IntroSpect Standard joins the IntroSpect UEBA family, along with new features added to the company’s flagship offering, Aruba IntroSpect Advanced. The expansion of the IntroSpect UEBA family offers security teams more choice and a quick way to implement UEBA.
Aruba IntroSpect Standard is an easy way for organisations to start employing UEBA machine learning security with as few as three data sources, accelerating an organisation’s time-to-protect corporate and customer data. It is designed for basic monitoring and detection of anomalous and often, subtle, behaviours on the network and across mobile, cloud, and IoT devices and applications, to identify early signs of attack expansion and beaconing, as well as data exfiltration.
It ingests common data sources including Microsoft Active Directory or other LDAP authentication records and identity information, and firewall logs from sources such as Checkpoint, Palo Alto Networks™, or Aruba monitoring (AMON) logs from Aruba infrastructure. Action can be taken quickly using ClearPass to quarantine, restrict, or remove identified threats.
Security teams deploying IntroSpect Standard can easily upgrade to IntroSpect Advanced as their requirements expand.
Aruba IntroSpect Advanced delivers a wider set of security capabilities than IntroSpect Standard to provide attack detection by correlating across a broader array of data sources, aiding in faster incident investigation and improved threat-hunting, search and deep forensics. Included are more than 100 supervised and unsupervised machine learning models that provide unmatched analytics and forensics from data such as packets, flows, logs, alerts and endpoints, as well as mobile, cloud and IoT traffic, increasing an organisation’s effectiveness at identifying risk.
New features for Aruba IntroSpect Advanced include:
* Smarter Security with Dynamic Machine Learning, which allows security teams to easily customise IntroSpect’s analytical models based on the current threat environment and protection priorities. Included is “chaining”, in which the 100+ out-of-the box machine learning models can be linked together to construct new detection scenarios and associated risk scores.
* Classifying Mobile, Cloud and IoT with Device Peer Grouping, which utilises the ClearPass profiling functionality to group like devices even when known only by their IP address. For example, ClearPass will classify a surveillance camera or a factory sensor, and IntroSpect will benchmark its behaviour among its peer group. Introspect will flag unusual device behaviour based on peer group comparisons, which is important in extending UEBA functionality to the growing classes of IoT devices.
* Faster Remediation with Integrated Attack Response, enabling security analysts to respond to an attack by triggering an action for ClearPass directly from the IntroSpect console.
Embedded into Aruba’s networking infrastructure is the Aruba Secure Core, which provides the necessary protection required for any network, including secure boot, embedded firewalls, centralised encryption, deep packet inspection and intrusion prevention. Aruba’s unique infrastructure design helps eliminate the danger of physical tampering while securing and monitoring network traffic.
Integrating Aruba IntroSpect UEBA and Aruba ClearPass into the Aruba Secure Core provides a seamless path of protection from device discovery and access to attack detection and response. This gives Aruba customers the unique ability to detect an attack and then take automated or analyst-initiated action to protect organisations’ valuable assets, ranging from network re-authentication to quarantining to blacklisting users and devices.
