Tags Share this article 6/14/16 Published Hospitals are increasingly becoming a favored target of cyber criminals. Yet if you think about medical equipment that is vulnerable to being hacked at a hospital, you might not immediately think of high-end, critical equipment such as MRI and X-ray scanners, and nuclear medicine devices. After all, these devices go through rigorous approval processes by the US Food & Drug Administration (FDA) before they are approved for safe use on patients. Yet today many, if not most, medical devices, have computers embedded in them, are connected to the hospital network, and often to the internet as well, so they provide a potential attack vector for cyber criminals. In late 2015 security researchers found that thousands of medical devices were vulnerable to attack and exposed to the public Internet. Interestingly, these researchers also found that many of the devices in question were running Windows XP – which is no longer supported or updated by Microsoft – and did not run antivirus software to protect them against malware. This combination raises an obvious security red flag. Ironically, these security vulnerabilities were further exacerbated because of the very FDA approvals process that certifies the devices. The approval process is, quite rightly, extremely rigorous. It is also lengthy and expensive. And if a manufacturer or vendor makes a change to a device, it needed to be re-certified. Until very recently, a ‘change’ to a medical device meant any sort of change – including patching devices’ operating systems and firmware to close off potential network security vulnerabilities. You can see where this is going: making simple updates to medical equipment to improve its defenses against cyberattacks was made that much more difficult and complex for the device manufacturers, because of the need for FDA re-certification every time a change was made. And of course, this potential delay in patching vulnerabilities made it easy for a hacker to try and ‘update’ the device in his own way, for criminal purposes. Hackers are usually not too concerned about getting FDA approval for their work. Fortunately, the FDA released new guidelines last year that allowed equipment manufacturers to patch software as required without undergoing re-certification—provided the change or modification does not ‘significantly affect the safety or effectiveness of the medical device’. That’s good news – but it’s not quite the end of the story. The FDA’s guidelines are only a partial panacea to the overall problem. They overlook the fact that many medical devices are running obsolete operating systems like Windows XP. What’s more, the actual process of applying patches to the computers in medical devices can vary enormously from manufacturer to manufacturer, with some patches needing to be downloaded and applied manually, while others may be pushed automatically. In either case, there could still be a window of weeks, months or even years before the device’s vendor issues a patch for a given vulnerability – a window that a hacker could exploit before the hospital’s IT team becomes aware that the vulnerability exists. This means that hospitals need to take great care when it comes to structuring and segmenting their network . It is vital that connected medical devices – particularly those where the internal OS may be out of date – are placed within defined, segregated segments of the network, and robustly protected with next-generation firewalls, web proxies and other filters. While network segmentation and filtering will not protect unpatched or obsolete operating system, they will ensure that the hospital’s network is secured to the best of its ability .

Application Connectivity Management How to Make Container Security Threats More Containable Prof. Avishai Wool 2 min read Prof. Avishai Wool Short bio about author here Lorem ipsum dolor sit amet consectetur. Vitae donec tincidunt elementum quam laoreet duis sit enim. Duis mattis velit sit leo diam. Tags Share this article 9/8/22 Published As cloud adoption and digital transformation increases, more sensitive data from applications is being stored in data containers. This is why effective container security controls to securely manage application connectivity is an absolute must. AlgoSec CTO and Co-Founder, Prof. Avishai Wool provides some useful container security best practices to help you do just that. What is Container Security? Organizations, now more than ever, are adopting container technology. Instead of powering up servers and instances in the cloud, they are using containers to run business applications. Securing these is equally as important as securing other digital assets that the business is dependent on. There are two main pillars to think about: The code: you want to be able to scan the containers and make sure that they are running legitimate code without any vulnerabilities. The network: you need to control access to and from the container (what it can connect to), both inside the same cluster, other clusters, and different parts of the network. How critical is container security to managing application connectivity risks? To understand the role of container security within the overall view of network security, there are three points to consider. First, if you’re only concerned about securing the containers themselves, then you’re looking at nano-segmentation , which involves very granular controls inside the applications. Second, if you’re thinking about a slightly wider scope then you may be more concerned with microsegmentation , where you are segmenting between clusters or between servers in a single environment. Here you will want to enforce security controls that determine the allowable communication between specific endpoints at specific levels. Finally, if the communication needs to go further, from a container inside one cluster within one cloud environment to an asset that’s outside of the data center, then that might need to go through broader segmentation controls such as zoning technologies, security groups or a firewall at the border. So, there are all these layers where you can place network security policies. When you’re looking at a particular connectivity request (say for a new version of an application) from the point of view of a given container you should ask yourself: what is the container connected to? What is it communicating with? Where are those other sides of the connectivity placed? Based on that determination, you will then know which security controls you need to configure to allow that connectivity through the network. How does containerization correlate with application centric security policy management? There are a number of different aspects to the relationship between container security and application security. If an application uses containers to power up workloads then container security is very much an integral part of application security. When you’re adding new functionality to an application, powering up additional containers, asking containers to perform new tasks whereby they need to connect to additional assets, then the connectivity of those containers needs to be secured. And security controls need to be regulated or changed based on what the application needs them to do. Another factor in this relationship is the structure of the application. All the containers that run and support the application are often located in one cluster or a micro-segment of the network. So, much of the communication takes place inside that cluster, between one container or another, all in the same cluster. However, some of it can go to another cluster or somewhere that’s not even containerized. This is actually a good thing from an application point of view as the container structure can be used to understand the application structure as well. Not sure about container orchestration? Here’s what to know Container orchestration is part of a bigger orchestration play which is, in general, related to the concept of infrastructure as code. You want to be able to power up an environment with all the assets it requires, and have it function simultaneously so you can duplicate it. There are various orchestration technologies that can be used to deploy the security policies for containers , which is an excellent way to maintain container-based applications in a consistent and repeatable manner. Then if you need to double it or multiply it by 100, you can get cookie-cutter copies of the same thing. How will container security solutions play out in the future? Organizations today have the technology to enforce security controls at the container level, but these controls are very granular and it’s time-consuming to set policies and enforce them, particularly with issues like staff or skills shortages. Looking ahead, companies are likely to take a hierarchical view where container-based security is controlled at the application level by app owners or developers, and at the broader levels to ensure that the measures deployed throughout the network have the same degree of sophistication. Procedures and tooling are all evolving, so we don’t have a definitive answer as to how this will all end up. What are organizations going to be doing? Where will they place their controls? Who has the power to make the changes? When newer technologies are deployed, customer adoption will be crucial to understanding what makes the most sense. This will be interesting as there will be multiple scenarios to help companies master their security blueprint as we move forward.

Firewall Change Management Change automation: A step-by-step guide to network security policy change management Avivi Siman Tov 2 min read Avivi Siman Tov Short bio about author here Lorem ipsum dolor sit amet consectetur.

Tags Share this article 10/21/21 Published Avivi Siman-Tov, Director of Product Management at AlgoSec, discusses the benefits of network automation and takes us through a step-by-step process to standardize change management In today’s fast-paced, data-driven environment, the only constant that businesses can bank on is change. For organizations to function and compete in the modern digital landscape, they need their data to be able to move freely and unobstructed through every branch of their business, unimpeded by security issues that require constant manual attention. The network is arguably the beating heart of an organization but keeping it ticking requires more maintenance than it once did, owing to constantly changing risk profiles and circumstances. That’s why a greater number of businesses are turning to change automation to bridge the gap between network alerts and the action that needs to be taken. Barriers to automation According to Gartner , organizations that can automate more than 70% of their network changes can reduce the number of outages by at least 50% and deliver services up to 50% faster. That’s because a lot of legacy solutions tend to take a reactive rather than proactive approach to dealing with security. There are multiple controls in place that simply don’t talk to each other. While most businesses get alerts from SIEM solutions and vulnerability scanners, responding to them turns into a full-time job, distracting your team from other important work they could be doing. Most organizations know that manual policy changes impact their productivity, but they’re afraid to take the leap to automation because of an ill-placed perception around security. Production environments in all organizations are maintained by different teams — for example, DevOps, maintenance, cloud security, IT, and more. Not all of these teams are educated to the same level in security matters, and some see it as a constraint that slows their work. This can lead to conflict between teams, which means that automation is not always welcome. Despite some resistance to change, enterprise-wide change automation makes it possible to transform network security policies without needing to reinvent the wheel or replace existing business processes. Automation and actionable intelligence are proven to enhance security and business agility without the stress often associated with misconfigurations caused by manual, ad-hoc processes. A typical network change workflow By elevating firewall change management from a manual, arduous task to a fully automated, zero-touch process, networks can become more agile and organizations far more adaptive. There are several steps that organizations need to take towards complete network security automation, from a simple change request through to implementation and validation. Let’s take a look at the most common steps in establishing automation for a simple change request. Step 1 – Request a network change Every change begins with a request. At this stage, you need to clarify who is asking for the amendment and why because sometimes the request is unnecessary or covered by an existing ruleset. Step 2 – Find relevant security devices Once this request is translated, the change automation platform will handle the request and implement the changes to hybrid networks. The administrator will be able to see which firewall and routing devices are involved and what impact the change will have. Step 3 – Plan change The change automation platform understands how to deal with different vendor-specific settings and how to implement the requests in a way that avoids creating any duplicates. Step 4 – Risk check The administrator will get a ‘ what if’ analysis, which checks the change for any risks. In this phase, the decision as to whether to allow the change and expose the network to the risk mentioned is in the hands of the network admin or security manager, depending on who is handling this phase. Step 5 – Push change to device Once planned changes are approved, the ‘magic’ happens. The change automation platform implements and pushes the changes to the desired devices automatically, either through APIs or directly to the device (CLI). This is a fully automated action that can be conducted on multiple devices, whether cloud-based or on-premises. The push can be done in a scheduled manner, in your maintenance window, or on-demand. Step 6 – Validate change At the end of each request, the solution will check that the request was successfully implemented across all devices. The solution also provides ongoing audits of the whole process, enabling easy checking of each stage. Step 7 – Documentation and logging Network security automation platforms can provide you with a full, automated audit trail. Documentation happens on the go, saving IT and security teams time and accelerating tedious network compliance management tasks. Put your trust in network automation While change management is complex stuff, the decision for your business is simple. It’s like the engine of an expensive car. Would you drive at high speeds if you didn’t have your brakes tested or a steering wheel to keep your course straight? Hopefully, the answer is no. With AlgoSec FireFlow , you can automate the security policy change process without introducing any element of risk, vulnerability, or compliance violation. AlgoSec FireFlow allows you to analyze every change before it is introduced, and validate successful changes as intended, all within your existing IT Service Management (ITSM) solutions .
