New Kubernetes security posture management (KSPM) and agentless runtime protection empower organisations to defend K8s-based applications against multiple threats

Aqua Security announced a suite of new Kubernetes-native security capabilities, providing a holistic approach to securing applications that run on Kubernetes across the development, deployment, and runtime phases of the application lifecycle. The company also announced significant new features in its Cloud Security Posture Management (CSPM) solution. These new capabilities are integrated into Aqua’s cloud native security platform, covering the spectrum of deployment options across containers, VMs, and serverless functions.

In a recent research note, Michael Isbitski and Frank Catucci from Gartner asserts that “Kubernetes’ inherent complexity often leads to outdated versions and misconfiguration by organisations, making clusters susceptible to compromise. Though some security mechanisms are included by design, K8s by itself is not a security offering, and security settings aren’t always enabled by default. Protecting a K8s cluster is a significant undertaking, requiring both substantial understanding of the underlying technology and engineering expertise to configure it all.” 

Kubernetes Security Posture Management (KSPM)

KSPM automates set of policies and controls to secure configuration and complianceAqua’s new Kubernetes security solution addresses the complexity and short supply of engineering expertise required to configure Kubernetes infrastructure effectively and automatically by introducing KSPM - Kubernetes Security Posture Management, a coherent set of policies and controls to automate secure configuration and compliance. Additionally, Aqua now offers new agentless runtime protection capabilities that use Kubernetes itself to deploy security controls into pods, leveraging and extending the native capabilities built into Kubernetes.

The large-scale use of Kubernetes, as well as developments in the threat landscape, necessitate a comprehensive approach to securing applications that goes beyond generic benchmarks, providing seamless workload protection in runtime,” noted Amir Jerbi, CTO and co-founder at Aqua. “We’ve been working with our enterprise customers to make it easier to securely deploy and seamlessly protect applications that run on Kubernetes, while complementing our existing capabilities in Kubernetes and container security.

KSPM new and innovative capabilities

  • Kubernetes Assurance Policies: With more than 20 predefined rules available out of the box, and the ability to use OPA (Open Policy Agent) Rego rules, these policies define which Pods may be deployed in a cluster based on multiple parameters. These policies work in conjunction with Aqua’s Image Assurance Policies to control which containers run in one's cluster based on both their image contents and configuration, as well as Pod configuration.
  • Kubernetes Roles and Subjects Assessment: Reduces administration overhead of maintaining Kubernetes user and service account privileges by identifying risks and suggesting their remediation. This addresses the least privilege security gaps while diminishing the need for Kubernetes security expertise, which is in short supply.

These new capabilities join Aqua’s existing certified CIS benchmark testing (powered by Aqua’s open source Kube-Bench), and penetration testing (powered by Aqua’s open source Kube-Hunter), providing enterprises with comprehensive insight into the security posture of their Kubernetes cluster, and the ability to address gaps efficiently with no need for specialised expertise.

Enhanced security extensions           

With its new Kubernetes Runtime Protection module, Aqua introduces a new model for deploying security runtime controls in a Kubernetes cluster, complementing its existing container runtime security deployment options. This new model leverages Kubernetes Admission Controllers to deploy and govern sidecar containers within Pods, in a similar fashion to other cloud native tools such as Envoy. This mode of deployment enables greater automation of deployment and does not require any privileges on the node’s host OS while providing dynamic runtime controls such as container drift prevention, behavioural controls, and network controls.

In addition to the extensions to Kubernetes security capabilities, the latest release adds many new features and enhancements including:

  • New Customisable Dashboard: Provides a clear view of the overall security status of your cloud native environment with dedicated widgets for key areas, such as host and image/container security, and drag & drop design. The new dashboard supports Aqua’s RBAC model to filter viewable data according to user role permissions.
  • AWS Bottlerocket Support: The new AWS operating system for running containers is now available as a protected workload platform.
  • Auto-Remediation for Azure in Aqua CSPM: Aqua CSPM now provides remediation advice and auto-remediation options for Azure cloud services, previously available for AWS.
  • New Compliance Reports in Aqua CSPM: Aqua CSPM now provides out-of-the-box compliance reports for additional compliance reporting, including SOC 2 Type 2, ISO27001, NIST SP 800-53, and NIST CSF.
  • VM Security: Now allows flexible scan scheduling, scan history review, and malware scans on mounted NFS shares.

How smart technology is simplifying safety and security in retirement villages
How smart technology is simplifying safety and security in retirement villages

James Twigg is the Managing Director of Total Integrated Solutions (TIS), an independent life safety, security and communication systems integrator, specialising in design & consultancy, technology and regulatory compliance. Total Integrated Solutions work primarily with retirement villages, helping to ensure the safety of residents in numerous retirement villages across the country. In this opinion piece, James shares how smart technology is helping security teams and care staff alike in ensuring the safety and security of their spaces, amid the COVID-19 pandemic and beyond. Impact of smart technology Smart technology is having an impact on pretty much every aspect of our lives Smart technology is having an impact on pretty much every aspect of our lives. From how we travel, to how we work, to how we run our homes. It’s not unusual to have Alexa waking us up and ordering our groceries or Nest to be regulating the temperature and energy in our homes. And while there’s a popular misconception that people in their later years are allergic to technology, retirement villages and care homes are experiencing significant innovation too. And the result is not only improved quality of life for residents, but also improved safety and security systems for management teams. Switching to converged IP systems I’ve been working in the life safety and security industry for over fifteen years. When I first joined TIS, much of the sector was still very analogue, in terms of the technology being installed and maintained. Slowly but surely, we’ve been consulting and advising customers on how to design, install and maintain converged IP systems that all talk to each other and work in tandem. I'm excited to say retirement villages are some of the top spaces leading the way, in terms of technological advancement. Improving the quality of life for residents A move into a retirement village can be daunting and one of the key concerns that we hear about is the loss of independence. No one wants to feel like they are being monitored or to have someone constantly hovering over them. One of the ways we’ve used smart technology to maintain residents' independence is through devices, such as health monitors and motion sensors. For example, instead of having a member of staff check-in on residents every morning, to ensure they are well, sensors and analytics can automatically detect changes in routine and alert staff to possible problems. Similarly, wearable tech, such as smart watches give residents a chance to let staff know they are okay, without having to tell them face-to-face. As our retirement village customers have told us, a simple ‘I’m okay’ command can be the difference between someone feeling independent versus someone feeling monitored. Simplifying and improving security systems Smart technology gives care staff and security oversight of the needs of residents For the teams responsible for the safety of the people, places and spaces within retirement villages, smart technology is helping to improve and simplify their jobs. Smart technology gives care staff and security oversight of the needs of residents, and ensures rapid response if notified by an emergency alert, ensuring they know the exact location of the resident in need. And without the need to go and physically check-in on every resident, staff and management can ensure staff time is being used effectively. Resources can be distributed where they are needed to ensure the safety and wellbeing of those residents who need extra consideration. 24/7 surveillance When planning the safety and security for retirement villages, and other residential spaces, it’s no use having traditional systems that only work effectively for 12 hours a day or need to update during the evening. Surveillance needs to be 24/7 and smart technology allows that without the physical intrusion into people’s spaces and daily lives. Smart technology ensures that systems speak to each other and are easily and effectively managed on one integrated system. This includes video surveillance, which has also become much more effective as a result of advanced video analytics, which automatically warn staff of suspicious behaviour. Securing spaces amid COVID-19 This year has, of course, brought new challenges for safety. COVID-19 hit the retirement and residential care sectors hard, first with the initial wave of infections in mid-2020 and then, with the subsequent loneliness caused by the necessary separation of families. As essential workers, we worked closely with our customers to make sure they had everything they needed As essential workers, we worked closely with our customers to make sure they had everything they needed during this time, equipping residents with tablet devices to ensure they could stay connected with their families and friends. It allowed residents to keep in touch without risking transferring the virus. Thermal cameras and mask detection And now that we’re emerging out of COVID-19 restrictions and most residents can see their families again, we’re installing systems like thermal cameras and mask detection, so as to ensure that security will be alerted to anyone in the space experiencing a high temperature or not wearing proper PPE. Such steps give staff and families alike, the peace-of-mind that operational teams will be alerted at the earliest possible moment, should a COVID-19 risk appear. Thinking ahead to the next fifteen years, I’m excited at the prospect of further technological advancements in this space. Because at the end of the day, it’s not about how complex your security system is or how you compete in the industry. It’s about helping teams to protect the people, spaces and places that matter. I see smart technology playing a huge role in that for years to come.

ASSA ABLOY’s Code Handle protects Fylab physiotherapy practice with secure PIN-operated handles
ASSA ABLOY’s Code Handle protects Fylab physiotherapy practice with secure PIN-operated handles

In all medical settings, people are coming and going all day. Therapists leave their personal belongings in changing rooms, patients want privacy in consulting rooms, open or unlocked doors can be an invitation to opportunists. Yet keeping track of mechanical keys can be a tiresome task for a small practice. There is a solution: the Code Handle PIN lock from ASSA ABLOY. In Irun, in Spain’s Basque country, Fylab sought easy electronic door security for their consulting rooms. These rooms house expensive specialist equipment for the various therapeutic disciplines offered by Fylab. Requirements were straightforward: a simple, secure, keyless access solution designed to work in a facility that gets a lot of daily traffic from professionals and the public. They needed a locking device that is easy to retrofit and incorporates a contemporary device design to match with Fylab’s modern medical workplace. Adding electronic security to room doors The Code Handle PIN-locking door handle added electronic security to three consulting-room doors at FylabThe Code Handle PIN-locking door handle added electronic security to three consulting-room doors at Fylab – without wires or cables. Two screws fit a Code Handle to almost any interior door (between 35mm to 80mm thick). One doesn’t even need to change their existing door cylinder. “I am no artist or handyman, but I managed to fit the handles within 10 minutes,” says Fylab founder, Borja Saldias Retegui. Code Handle adds electronic security to almost any interior door without disrupting its aesthetics. If one needs to secure a door facing a public space, Code Handle does it subtly and with zero hassle. At Fylab, Code Handle devices locks both wooden and glass doors, keeping equipment and therapists’ personal belongings safe. Allows up to 9 different PIN numbers “We like the solution a lot because we can do away with keys,” adds Borja. Code Handle removes the need to track cumbersome keys or install expensive access control. Because every Code Handle allows up to 9 different PIN numbers (4 to 6 digits), all authorised staff at Fylab can have their own security code. Two standard batteries (CR2) slot inside the handle, typically lasting 30,000 lock/unlock cycles before replacement The practice manager cancels or amends PINs at any time using the master PIN. Two standard batteries (CR2) slot inside the handle, typically lasting 30,000 lock/unlock cycles before replacement. It’s simple. “Code Handle is unique in comparison to common code door locks: it has the code function and battery incorporated inside its handle, so you don’t need to make extra modifications to your door,” explains Lars Angelin, Business Development Manager for Code Handle at ASSA ABLOY EMEA. Auto-locking feature of Code Handle Auto-locking is another helpful feature. When the door closes, Code Handle locks it automatically. One doesn’t need to put down whatever they are carrying, and no one can open it from the outside while they are not looking. To keep the door open briefly, one can simply hold Code Handle down for 5 seconds and it remains temporarily unlocked. For convenience, Code Handle always opens freely from the inside. “Code Handle provides the simplest solution for access control in a small facility,” says Borja.

What are the challenges and benefits of mobile access control?
What are the challenges and benefits of mobile access control?

There is a broad appeal to the idea of using a smartphone or wearable device as a credential for physical access control systems. Smartphones already perform a range of tasks that extend beyond making a phone call. Shouldn’t opening the door at a workplace be among them? It’s a simple idea, but there are obstacles for the industry to get there from here. We asked this week’s Expert Panel Roundtable: What are the challenges and benefits of mobile access control solutions?
