Zero Trust – Demystified

Article | July 29, 2020

1. Zero Trust – Demystified Everyone seems to be talking about Zero Trust in the security world at the moment. Unfortunately there seems to be multiple definitions of this depending on which vendor you ask. To help others understand what Zero Trust is, this white paper covers the key aspects of a Zero Trust model. 1.1. What is Zero Trust Zero Trust is a philosophy and a related architecture to implement this way of thinking founded by John Kindervag in 2010. What it isn’t, is a particular technology! There are three key components to a Zero Trust model: 1. User / Application authentication – we must authenticate the user or the application (in cases where applications are requesting automated access) irrefutably to ensure that the entity requesting access is indeed that entity 2. Device authentication – just authenticating the user / application is not enough. We must authenticate the device requesting access as well 3. Trust – access is then granted once the user / application and device is irrefutably authenticated. Essentially, the framework dictates that we cannot trust anything inside or outside your perimeters. The zero trust model operates on the principle of 'never trust, always verify’. It effectively assumes that the perimeter is dead and we can no longer operate on the idea of establishing a perimeter and expecting a lower level of security inside the perimeter as everything inside is trusted. This has unfortunately proven true in multiple attacks as attackers simply enter the perimeter through trusted connections via tactics such as phishing attacks. 1.2. Enforcing the control plane In order to adequately implement Zero Trust, one must enforce and leverage distributed policy enforcement as far toward the network edge as possible. This basically means that granular authentication and authorisation controls are enforced as far away from the data as possible which in most cases tends to be the device the user is using to access the data. So in essence, the user and device are both untrusted until both are authenticated after which very granular role based access controls are enforced. In order to achieve the above, a control plane must be implemented that can coordinate and configure access to data. This control plane is technology agnostic. It simply needs to perform the function described above. Requests for access to protected resources are first made through the control plane, where both the device and user must be authenticated and authorised. Fine-grained policy can be applied at this layer, perhaps based on role in the organization, time of day, or type of device. Access to more secure resources can additionally mandate stronger authentication. Once the control plane has decided that the request will be allowed, it dynamically configures the data plane to accept traffic from that client (and that client only). In addition, it can coordinate the details of an encrypted tunnel between the requestor and the resource to prevent traffic from being ‘sniffed on the wire’. 1.3. Components of Zero Trust and the Control Plane Enforcing a Zero Trust model and the associated control plan that instructs the data plane to accept traffic from that client upon authentication requires some key components for the model to operate. The first and most fundamental is micro-segmentation and granular perimeter enforcement based on: Users Their locations Their devices and its security posture Their Behaviour Their Context and other data The above aspects are used to determine whether to trust a user, machine or application seeking access to a particular part of the enterprise. In this case, the micro-segmentation technology essentially becomes the control plane. Per the above section, encryption on the wire is a key component of Zero Trust. For any micro-segmentation technology to be an effective control plane, it must: Enforce traffic encryption between endpoints Authenticate the user and machine based on their identity and not the network segment they are coming from. 1.4. Zero Trust Technologies As stated earlier, Zero Trust is an architecture. Other than micro-segmentation, the following key technologies and processes are required to implement Zero Trust: Multifactor authentication – to enforce strong authentication Identity and Access Management – to irrefutably authenticate the user / application and the device User and network behaviour analytics – to understand the relative behaviours of the user and the network they are coming from and highlight any unusual behaviour compared to a pre-established baseline which may indicate a compromised identity Endpoint security – to ensure that the endpoint itself is clean and will not act as a conduit for an attacker to gain unauthorised access to data Encryption – to prevent ‘sniffing of traffic on the wire’ Scoring – establishing a ‘score’ based on the perimeters above that will then determine whether access can be granted or not Apart from the above key components, the following are needed as well: File system permissions – needed in order to implement role based access controls Auditing and logging – to provide monitoring capabilities in case unauthorised access is achieved Granular role based access controls – to ensure access is on a ‘need to know basis only’ Supporting processes – all of the above needs to be supported by adequate operational procedures, processes and a conducive security framework so that the model operates as intended Mindset and organisational change management – since Zero Trust is a shift in security thinking, a mindset change managed by robust change management is required to ensure the successful implementation of Zero Trust in an organisation. 1.5. Challenges with Zero Trust So Zero Trust sounds pretty awesome, right? So why haven’t organisations adopted it fully? As with any new technology or philosophy, there are always adoption challenges. Zero Trust is no different. At a high level, the key challenges in my experience are: Change resistance – Zero Trust is a fundamental shift in the way security is implemented. As a result, there is resistance from many who are simply used to the traditional perimeter based security model Technology focus as opposed to strategy focus – since Zero Trust is a model that will impact the entire enterprise, it requires careful planning and a strategy to implement this. Many are still approaching security from the angle that if we throw enough technology at it, it will be fine. Unfortunately, this thinking is what will destroy the key principles of Zero Trust Legacy systems and environments – legacy systems and environments that we still need for a variety of reasons were built around the traditional perimeter based security model. Changing them may not be easy and in some cases may stop these systems from operating Time and cost – Zero Trust is an enterprise wide initiative. As such, it requires time and investment, both of which may be scarce in an organisation. 1.6. Suggested Approach to Zero Trust Having discussed some challenges to adopting a Zero Trust model above, let’s focus on an approach that may allow an organisation to implement a Zero Trust model successfully: 1. Take a multi-year and multi-phased approach – Zero Trust takes time to implement. Take your time and phase the project out to spread the investment over a few financial years 2. Determine an overall strategy and start from there – since Zero Trust impacts the entire enterprise, a well-crafted strategy is critical to ensure success. A suggested, phased approach is: a. Cloud environments, new systems and digital transformation are good places to start – these tend to be greenfield and should be more conducive to a new security model b. Ensure zero trust is built into new systems, and upgrades or changes – build Zero Trust by design, not by retrofit. As legacy systems are changed or retired, a Zero Trust model should be part of the new deployment strategy c. Engage a robust change management program – mindset adjustment through good change management 3. Take a risk and business focus – this will allow you to focus on protecting critical information assets and justify the investments based on ROI and risk mitigation 4. Ensure maintenance and management of the new environment – as with everything, ensure your new Zero Trust deployment is well maintained and managed and does not degrade over time. To summarise, Zero Trust is a security philosophy and architecture that will change the way traditional perimeter based security is deployed. A key component of it is the control plane that instructs the data plane to provide access to data. Zero Trust dictates that access can only be granted once the user / application and device are irrefutably authenticated and even then this access is provided on a ‘need to know’ basis only. Micro-segmentation is a key technology component of Zero Trust implementation and this paper has stated other key technology components and processes that are needed to implement Zero Trust adequately. This paper has discussed some of the challenges with implementing Zero Trust which include change resistance as well as legacy systems. The paper then provided an approach to implementing Zero Trust which included taking a phased approach based on a sound strategy underpinned by a risk and business focused approach.

Security News This Week: A Tiny Piece of Tape Tricked Teslas Into Speeding Up 50 MPH

Article | February 22, 2020

This week was filled with wide-scale calamity. Hundreds of millions of PCs have components whose firmware is vulnerable to hacking which is to say, pretty much all of them. It's a problem that's been known about for years, but doesn't seem to get any better. Likewise, Bluetooth implementation mistakes in seven SoC—system on chips—have exposed at least 480 internet-of-things devices to a range of attacks. IoT manufacturers will often outsource components, so a mistake in one SoC can impact a wide range of connected doodads. The most troubling part, though, is that medical devices like pacemakers and blood glucose monitors are among the affected tech. YouTube Gaming, meanwhile, wants to take Twitch's crown as the king of videogame streaming. But its most-viewed channels are almost all scams and cheats, a moderation challenge that it'll have to take more seriously if it wants the legitimacy it's spending big money to attain. In another corner of Alphabet's world, hundreds of Chrome extensions were caught siphoning data from people who installed them, part of a sprawling adware scheme.

How Is Covid-19 Creating Data Breaches?

Article | March 30, 2020

Trevor is working from home for the first time. He loves the freedom and flexibility, but doesn’t read his company’s new BYOD policy. Sadly, he misses the fact that his home PC is not protected with updated security software nor the latest operating system patches. Kelcie’s home PC is faster than the old work laptop that she’s been issued to use during the pandemic. She decides to use a USB stick to transfer large files back and forth between her PCs to speed things up. After a few days, she does all her work on her home PC, using a “safe” virtual desktop app. But unbeknownst to her, there is a keylogger on her home PC.

Webroot: Widespread Lack of Cybersecurity Best Practices

Article | April 7, 2020

A new list of most and least cyber secure U.S. states shows a disturbing lack of cybersecurity best practices. According to Webroot‘s fourth annual ranking, New York, California, Texas, Alabama and Arkansas are the least cyber secure states in the country, while Nebraska, New Hampshire, Wyoming, Oregon and New Jersey are the most cyber secure. Tyler Moffitt, Webroot security analyst, tells us none of the states had an average score greater than 67%. Also, there is very little difference between the most secure and least secure states, he said. No state scored a “C” grade or higher. That underlines a lack of cybersecurity education and hygiene nationally. However, the most cyber secure state (Nebraska at 67%) did score substantially better than the least (New York at 52%). This score was calculated through a variety of action- and knowledge-based variables, including residents’ use of antivirus software, use of personal devices for work, use of default security settings, use of encrypted data backups, password sharing and reuse, social media account privacy, and understanding of key cybersecurity concepts like malware and phishing,” Moffitt said.
