6 Best Practices For Increasing Security In AWS In A Zero Trust World

  • Amazon Web Services (AWS) reported $6.6B in revenue for Q3, 2018 and $18.2B for the first three fiscal quarters of 2018.
  • AWS revenue achieved an impressive 46% year-over-year net sales growth between Q3, 2017 and Q3, 2018 and 49% year-over-year growth for the first three quarters of the year.
  • AWS’ 34% market share is bigger than its next four competitors combined with the majority of customers taken from small-to-medium sized cloud operators according to Synergy Research.
  • The many announcements made at AWS Re:Invent this year reflect a growing focus on hybrid cloud computing, security, and compliance.

Enterprises are rapidly accelerating the pace at which they’re moving workloads to Amazon Web Services (AWS) for greater cost, scale and speed advantages. And while AWS leads all others as the enterprise public cloud platform of choice, they and all Infrastructure-as-a-Service (IaaS) providers rely on a Shared Responsibility Model where customers are responsible for securing operating systems, platforms and data.  In the case of AWS, they take responsibility for the security of the cloud itself including the infrastructure, hardware, software, and facilities. The AWS version of the Shared Responsibility Model shown below illustrates how Amazon has defined securing the data itself, management of the platform, applications and how they’re accessed, and various configurations  as the customers’ responsibility:

Included in the list of items where the customer is responsible for security “in” the cloud is identity and access management, including Privileged Access Management (PAM) to secure the most critical infrastructure and data.

Increasing Security for IaaS in a Zero Trust World

Stolen privileged access credentials are the leading cause of breaches today. Forrester found that 80% of data breaches are initiated using privileged credentials, and 66% of organizations still rely on manual methods to manage privileged accounts. And while they are the leading cause of breaches, they’re often overlooked — not only to protect the traditional enterprise infrastructure — but especially when transitioning to the cloud.

Both for on-premise and Infrastructure-as-a-Service (IaaS), it’s not enough to rely on password vaults alone anymore. Organizations need to augment their legacy Privileged Access Management strategies to include brokering of identities, multi-factor authentication enforcement and “just enough, just-in-time” privilege, all while securing remote access and monitoring of all privileged sessions. They also need to verify who is requesting access, the context of the request, and the risk of the access environment. These are all essential elements of a Zero Trust Privilege strategy, with Centrify being an early leader in this space.

6 Ways To Increase Security in AWS

The following are six best practices for increasing security in AWS and are based on the Zero Trust Privilege model:

  1. Vault AWS Root Accounts and Federate Access for AWS Console

Given how powerful the AWS root user account is, it’s highly recommended that the password for the AWS root account be vaulted and only used in emergencies. Instead of local AWS IAM accounts and access keys, use centralized identities (e.g., Active Directory) and enable federated login. By doing so, you obviate the need for long-lived access keys.

  1. Apply a Common Security Model and Consolidate Identities

When it comes to IaaS adoption, one of the inhibitors for organizations is the myth that the IaaS requires a unique security model, as it resides outside the traditional network perimeter. However, conventional security and compliance concepts still apply in the cloud. Why would you need to treat an IaaS environment any different than your own data center? Roles and responsibilities are still the same for your privileged users. Thus, leverage what you’ve already got for a common security infrastructure spanning on-premises and cloud resources. For example, extend your Active Directory into the cloud to control AWS role assignment and grant the right amount of privilege.

  1. Ensure Accountability

Shared privileged accounts (e.g., AWS EC2 administrator) are anonymous. Ensure 100% accountability by having users log in with their individual accounts and elevate privilege as required. Manage entitlements centrally from Active Directory, mapping roles, and groups to AWS roles.

  1. Enforce Least Privilege Access

Grant users just enough privilege to complete the task at hand in the AWS Management Console, AWS services, and on the AWS instances. Implement cross-platform privilege management for AWS Management Console, Windows and Linux instances.

  1. Audit Everything

Log and monitor both authorized and unauthorized user sessions to AWS instances. Associate all activity to an individual, and report on both privileged activity and access rights. It’s also a good idea to use AWS CloudTrail and Amazon CloudWatch to monitor all API activity across all AWS instances and your AWS account.

  1. Apply Multi-Factor Authentication Everywhere

Thwart in-progress attacks and get higher levels of user assurance. Consistently implement multi-factor authentication (MFA) for AWS service management, on login and privilege elevation for AWS instances, or when checking out vaulted passwords.

Conclusion

One of the most common reasons AWS deployments are being breached is a result of privileged access credentials being compromised. The six best practices mentioned in this post are just the beginning; there are many more strategies for increasing the security in AWS.  Leveraging a solid Zero Trust Privilege platform, organizations can eliminate shared Amazon EC2 key pairs, using auditing to define accountability to the individual user account level, execute on least privilege access across every login, AWS console, and AWS instance in use, enforce MFA and enable a common security model.

How To Protect Healthcare Records In A Zero Trust World

  • There’s been a staggering 298.4% growth in the reported number of patient records breached as a result of insider-wrongdoing this year alone according to Protenus.
  • The total disclosed number of breached patient records has soared from 1.1M in Q1 2018 to 4.4M in Q3 2018 alone, 680K of which were breached by insiders.
  • There were 117 disclosed health breaches in the last 90 days alone.
  • On average it’s taking 402 days to discover a healthcare provider has been breached.

Diagnosing Healthcare’s Breach Epidemic

Using access credentials stolen from co-workers or stolen laptops, unethical healthcare insiders are among the most prolific at stealing and selling patient data of any insider threat across any industry. Accenture’s study, “Losing the Cyber Culture War in Healthcare: Accenture 2018 Healthcare Workforce Survey on Cybersecurity,” found that the most common ways healthcare employees financially gain from stealing medical records is to commit tax return and credit card fraud.

Treating healthcare’s breach epidemic needs to start by viewing every threat surface, access point, identity, and login attempt as the new security perimeter. Healthcare providers urgently need to take a “never trust, always verify” approach, adopting  Zero Trust Security to protect every threat surface using Next-Gen Access for end-user credentials and Privileged Access Management (PAM) for privileged credentials. One of the leaders in Next-Gen Access is Idaptive, a newly created spin-off of Centrify. Centrify itself is offering Zero Trust Privilege Services helping over half of the Fortune 100 to eliminate privileged access abuse, the leading cause of breaches today. Centrify Zero Trust Privilege grants least privilege access based on verifying who is requesting access, the context of the request, and the risk of the access environment.

18% of healthcare employees are willing to sell confidential data to unauthorized parties for as little as $500 to $1,000, according to a recent Accenture study. 24% of employees know of someone who has sold access to patient data to outsiders. 58% of all healthcare breaches are initiated by insiders. Confidential patient diagnosis, treatment, payment histories, and medical records are the most valuable on the Dark Web, selling for as much as $1,000 per record according to Experian.

Key insights from Protenus’ Breach Barometer illustrate how healthcare’s breach epidemic is growing exponentially:

  • There’s been a staggering 298.4% growth in the number of patient records breached as a result of insider-wrongdoing this year alone. In Q1 of this year, there were 4,597 patient records exfiltrated by insider wrong-doing, jumping to 70,562 in Q2 and soaring to 290,689 in Q3. Healthcare insiders can easily thwart healthcare systems’ legacy security approaches today by using compromised access credentials. Zero Trust Security, either in the form of Next-Gen Access for end-user credentials or Zero Trust Privilege for privileged access credentials has the potential to stop this

  • The total number of breached patient records has soared from 1.1M in Q1 of this year to 4.4M in Q3, a 58.7% jump in less than a year. Protenus found a total of 117 incidents were disclosed to U.S. Department of Health and Human Services (HHS) or the media in Q3 2018 alone. Details were disclosed for 100 of these incidents, affecting 4,390,512 patient records, the highest level ever recorded. Jumping from 1.1M medical records in Q1 to 4.4M in Q3, healthcare providers could easily see over 6.5M records breached in Q4 2018 alone.

  • Hackers targeted healthcare systems aggressively in Q3 of this year, exfiltrating 3.6M patient records in just 90 days. Compromised access credentials are hackers’ favorite technique for exfiltrating massive quantities of medical records they resell on the Dark Web or use to commit tax and credit card fraud. Healthcare providers need to minimize their attack surfaces, improve audit and compliance visibility, reduce risk, complexity, and costs across their modern, hybrid enterprises with Zero Trust. Healthcare providers need to shut down hackers now, taking away the opportunities they’re capitalizing on to exfiltrate medical records almost at will.
  • It takes 71 days on average for healthcare providers to realize their data is breached with one breach lasting over 15 years. Protenus found a wide variation in the length of time it takes healthcare providers to realize they’ve been breached and one didn’t know until 15 years after the initial successful breach. All breaches tracked by Protenus found that the insiders and/or hackers were successful in gaining access to a wealth of patient information including addresses, dates of birth, medical record numbers, healthcare providers, visit date, health insurance information, financial histories, and payment information.

Conclusion

Zero Trust is the antidote healthcare needs to treat its raging breach epidemic.  It’s exponentially growing as insiders’ intent on wrongdoing turn to exfiltrating patients’ data for personal gain. Hackers also find healthcare providers’ legacy systems among the easiest to access using stolen access credentials, exfiltrating millions of records in months. With every new employee and device being a new security perimeter on their networks, the time is now for healthcare providers to discard the old model of “trust but verify” which relied on well-defined boundaries. Zero Trust mandates a “never trust, always verify” approach to access, from inside or outside healthcare providers’ networks.

High-Tech’s Greatest Challenge Will Be Securing Supply Chains In 2019

Bottom Line: High-tech manufacturers need to urgently solve the paradox of improving supply chain security while attaining greater visibility across supplier networks if they’re going make the most of smart, connected products’ many growth opportunities in 2019.

The era of smart, connected products is revolutionizing every aspect of manufacturing today, from suppliers to distribution networks. Capgemini estimates that the size of the connected products market will be $519B to $685B by 2020. Manufacturers expect close to 50 percent of their products to be smart, connected products by 2020, according to Capgemini’s Digital Engineering: The new growth engine for discrete manufacturers. The study is downloadable here (PDF, 40 pp., no opt-in).

Smart, connected products free manufacturers and their supply chains from having to rely on transactions and the price wars they create. The smarter the product, the greater the services revenue opportunities. And the more connected a smart product is using IoT and Wi-Fi sensors the more security has to be designed into every potential supplier evaluation, onboarding, quality plan, and ongoing suppliers’ audits. High-tech manufacturers are undertaking all of these strategies today, fueling them with real-time monitoring using barcoding, RFID and IoT sensors to improve visibility across their supply chains.

Gaining even greater visibility into their supply chains using cloud-based track-and-trace systems capable of reporting back the condition of components in transit to the lot and serialized pack level, high-tech suppliers are setting the gold standard for supply chain transparency and visibility. High-tech supply chains dominate many other industries’ supplier networks on accuracy, speed, and scale metrics on a consistent basis, yet the industry is behind on securing its vast supplier network. Every supplier identity and endpoint is a new security perimeter and taking a Zero Trust approach to securing them is the future of complex supply chains. With Zero Trust Privilege, high-tech manufacturers can secure privileged access to infrastructure, DevOps, cloud, containers, Big Data, production, logistics and shipping facilities, systems and teams.

High-Tech Needs to Confront Its Supply Chain Security Problem, Not Dismiss It

It’s ironic that high-tech supply chains are making rapid advances in accuracy and visibility yet still aren’t vetting suppliers thoroughly enough to stop counterfeiting, or worse. Bloomberg’s controversial recent article,The Big Hack: How China Used a Tiny Chip to Infiltrate U.S. Companies, explains how Amazon Web Services (AWS) was considering buying Portland, Oregon-based Elemental Technologies for its video streaming technology, known today as Amazon Prime Video. As part of the due diligence, AWS hired a third-party company to scrutinize Elemental’s security all the way up to the board level. The Elemental servers that handle the video compression were assembled by Super Micro Computer Inc., a San Jose-based company in China. Nested on the servers’ motherboards, the testers found a tiny microchip, not much bigger than a grain of rice, that wasn’t part of the boards’ original design that could create a stealth doorway into any network the machines were attached to. Apple (who is also an important Super Micro customer) and AWS deny this ever happened, yet 17 people have confirmed Supermicro had altered hardware, corroborating Bloomberg’s findings.

The hard reality is that the scenario Bloomberg writes about could happen to any high-tech manufacturer today. When it comes to security and 3rd party vendor risk management, many high-tech supply chains are stuck in the 90s while foreign governments, their militaries and the terrorist organizations they support are attempting to design in the ability to breach any network at will. How bad is it?  81% of senior executives involved in overseeing their companies’ global supply chains say 3rd party vendor management including recruiting suppliers is riskiest in China, India, Africa, Russia, and South America according to a recent survey by Baker & McKenzie.

PriceWaterhouseCoopers (PwC) and the MIT Forum for Supply Chain Innovation collaborated on a study of 209 companies’ supply chain operations and approaches to 3rd party vendor risk management. The study, PwC and the MIT Forum for Supply Chain Innovation: Making the right risk decisions to strengthen operations performance, quantifies the quick-changing nature of supply chains. 94% say there are changes in the extended supply chain network configuration happening frequently. Relying on trusted and untrusted domain controllers from server operating systems that are decades old can’t keep up with the mercurial pace of supply chains today.

Getting in Control of Security Risks in High-Tech Supply Chains

It’s time for high-tech supply chains to go with a least privilege-based approach to verifying who or what is requesting access to any confidential data across the supply chains. Further, high-tech manufacturers need to extend access request verification to include the context of the request and the risk of the access environment. Today it’s rare to find any high-tech manufacturer going to this level of least-privilege access approach, yet it’s the most viable approach to securing the most critical parts of their supply chains.

By taking a least-privilege access approach, high-tech manufacturers and their suppliers can minimize attack surfaces, improve audit and compliance visibility, and reduce risk, complexity, and operating costs across their hybrid manufacturing ecosystem.

Key actions that high-tech manufacturers can take to secure their supply chain and ensure they don’t end up in an investigative story of hacked supply chains include the following:

  • Taking a Zero Trust approach to securing every endpoint provides high-tech manufacturers with the scale they need to grow. High-tech supply chains are mercurial and fast-moving by nature, guaranteeing they will quickly scale faster than any legacy approaches enterprise security management. Vetting and then onboarding new suppliers needs to start by protecting every endpoint to the production and sourcing level, especially for next-generation smart, connected products.
  • Smart, connected products and the product-as-a-service business models they create are all based on real-time, rich, secured data streams that aren’t being eavesdropped on with components no one knows about. Taking a Zero Trust Privilege-based approach to securing access to diverse supply chains is needed if high-tech manufacturers are going to extend beyond legacy Privileged Access Management (PAM) to secure data being generated from real-time monitoring and data feeds from their smart, connected products today and in the future.
  • Quality management, compliance, and quality audits are all areas high-tech manufacturers excel in today and provide a great foundation to scale to Zero Trust Privilege. High-tech manufacturers have the most advanced quality management, inbound inspection and supplier quality audit techniques in the world. It’s time for the industry to step up on the security side too. By only granting least-privilege access based on verifying who is requesting access, the context of the request, and the risk of the access environment, high-tech manufacturers can make rapid strides to improve supply chain security.
  • Rethink the new product development cycles for smart, connected products and the sensors they rely on, so they’re protected as threat surfaces when built. Designing in security to the new product development process level and further advancing security scrutiny to the schematic and board design level is a must-do. In an era of where we have to assume bad actors are everywhere, every producer of high-tech products needs to realize their designs, product plans, and roadmaps are at risk. Ensuring the IOT and Wi-Fi sensors in smart, connected products aren’t designed to be hackable starts with a Zero Trust approach to defining security for supplier, design, and development networks.

Conclusion

The era of smart, connected products is here, and supply chains are already reverberating with the increased emphasis on components that are easily integrated and have high-speed connectivity. Manufacturing CEOs say it’s exactly what their companies need to grow beyond transaction revenue and the price wars they create. While high-tech manufacturers excel at accuracy, speed, and scale, they are falling short on security. It’s time for the industry to re-evaluate how Zero Trust can stabilize and secure every identity and threat surface across their supply chains with the same precision and intensity quality is today.

How To Protect Healthcare IoT Devices In A Zero Trust World

  • Over 100M healthcare IoT devices are installed worldwide today, growing to 161M by 2020, attaining a Compound Annual Growth Rate (CAGR) of 17.2% in just three years according to Statista.
  • Healthcare executives say privacy concerns (59%), legacy system integration (55%) and security concerns (54%) are the top three barriers holding back Internet of Things (IoT) adoption in healthcare organizations today according to the Accenture 2017 Internet of Health Things Survey.
  • The global IoT market is projected to soar from $249B in 2018 to $457B in 2020, attaining a Compound Annual Growth Rate (CAGR) of 22.4% in just three years according to Statista.

Healthcare and medical device manufacturers are in a race to see who can create the smartest and most-connected IoT devices first. Capitalizing on the rich real-time data monitoring streams these devices can provide, many see the opportunity to break free of product sales and move into more lucrative digital service business models. According to Capgemini’s “Digital Engineering, The new growth engine for discrete manufacturers,” the global market for smart, connected products is projected to be worth $519B to $685B by 2020. The study can be downloaded here (PDF, 40 pp., no opt-in). 47% of a typical manufacturer’s product portfolio by 2020 will be comprised of smart, connected products. In the gold rush to new digital services, data security needs to be a primary design goal that protects the patients these machines are designed to serve. The following graphic from the study shows how organizations producing smart, connected products are making use of the data generated today.

Healthcare IoT Device Data Doesn’t Belong For Sale On The Dark Web

Every healthcare IoT device from insulin pumps and diagnostic equipment to Remote Patient Monitoring is a potential attack surface for cyber adversaries to exploit. And the healthcare industry is renowned for having the majority of system breaches initiated by insiders. 58% of healthcare systems breach attempts involve inside actors, which makes this the leading industry for insider threats today according to Verizon’s 2018 Protected Health Information Data Breach Report (PHIDBR).

Many employees working for medical providers are paid modest salaries and often have to regularly work hours of overtime to make ends meet. Stealing and selling medical records is one of the ways those facing financial challenges look to make side money quickly and discreetly. And with a market on the Dark Web willing to pay up to $1,000 or more for the most detailed healthcare data, according to Experian, medical employees have an always-on, 24/7 marketplace to sell stolen data. 18% of healthcare employees are willing to sell confidential data to unauthorized parties for as little as $500 to $1,000, and 24% of employees know of someone who has sold privileged credentials to outsiders, according to a recent Accenture survey. Healthcare IoT devices are a potential treasure trove to inside and outside actors who are after financial gains by hacking the IoT connections to smart, connected devices and the networks they are installed on to exfiltrate valuable medical data.

Healthcare and medical device manufacturers need to start taking action now to secure these devices during the research and development, design and engineering phases of their next generation of IoT products. Specifying and validating that every IoT access point is compatible and can scale to support Zero Trust Security (ZTS) is essential if the network of devices being designed and sold will be secure. ZTS is proving to be very effective at thwarting potential breach attempts across every threat surface an organization has. Its four core pillars include verifying the identity of every user, validating every device, limiting access and privilege, and utilizing machine learning to analyze user behavior and gain greater insights from analytics.

The First Step Is Protect Development Environments With Zero Trust Privilege

Product research & development, design, and engineering systems are all attack surfaces that cyber adversaries are looking to exploit as part of the modern threatscape. Their goals include gaining access to valuable Intellectual Property (IP), patents and designs that can be sold to competitors and on the Dark Web, or damaging and destroying development data to slow down the development of new products. Another tactic lies in planting malware in the firmware of IoT devices to exfiltrate data at scale.

Attack surfaces and the identities that comprise the new security perimeter of their companies aren’t just people; they are workloads, services, machines, and development systems and platforms. Protecting every attack surface with cloud-ready Zero Trust Privilege (ZTP) which secures access to infrastructure, DevOps, cloud, containers, Big Data, and the entire development and production environment is needed.

Zero Trust Privilege can harden healthcare and medical device manufacturers’ internal security, only granting least privilege access based on verifying who is requesting access, the context of the request, and the risk of the access environment. By implementing least privilege access, healthcare and medical device manufacturers would be able to minimize attack surfaces, improve audit and compliance visibility, and reduces risk, complexity, and costs across their development and production operations.

The Best Security Test Of All: An FDA Audit

Regulatory agencies across Asia, Europe, and North America are placing a higher priority than ever before on cybersecurity to the device level. The U.S. Food & Drug Administration’s Cybersecurity Initiative is one of the most comprehensive, providing prescriptive guidance to manufacturers on how to attain higher levels of cybersecurity in their products.

During a recent healthcare device and medical device manufacturer’s conference, a former FDA auditor (and now Vice President of Compliance) gave a fascinating keynote on the FDA’s intent to audit medical device security at the production level. Security had been an afterthought or at best a “trust but verify” approach that relied on trusted versus untrusted machine domains. That will no longer be the case, as the FDA will now complete audits that are comparable to Zero Trust across manufacturing operations and devices.

As Zero Trust Privilege enables greater auditability than has been possible in the past, combined with a “never trust, always verify” approach to system access, healthcare device, and medical products manufacturers should start engineering in Zero Trust into their development cycles now.
