Chaperone applies security best practices and manages platform security so customers can focus on their business. Our platform is designed to protect customers from threats by applying security controls at every layer from physical to application, isolating customer applications and data, and with its ability to rapidly deploy security updates without customer interaction or service interruption.
Security Assessments and Compliance
Chaperone’s physical infrastructure is hosted and managed within Amazon’s secure data centers and utilize the Amazon Web Service (AWS) technology. Amazon continually manages risk and undergoes recurring assessments to ensure compliance with industry standards. Amazon’s data center operations have been accredited under: • ISO 27001 • SOC 1 and SOC 2/SSAE 16/ISAE 3402 (Previously SAS 70 Type II) • PCI Level 1 • FISMA Moderate • Sarbanes-Oxley (SOX)
We use PCI compliant payment processor Stripe for encrypting and processing credit card payments. Chaperone’s infrastructure provider is PCI Level 1 compliant.
Chaperone utilizes ISO 27001 and FISMA certified data centers managed by Amazon. Amazon has many years of experience in designing, constructing, and operating large-scale data centers. This experience has been applied to the AWS platform and infrastructure. AWS data centers are housed in nondescript facilities, and critical facilities have extensive setback and military grade perimeter control berms as well as other natural boundary protection. Physical access is strictly controlled both at the perimeter and at building ingress points by professional security staff utilizing video surveillance, state of the art intrusion detection systems, and other electronic means. Authorized staff must pass two-factor authentication no fewer than three times to access data center floors. All visitors and contractors are required to present identification and are signed in and continually escorted by authorized staff. Amazon only provides data center access and information to employees who have a legitimate business need for such privileges. When an employee no longer has a business need for these privileges, his or her access is immediately revoked, even if they continue to be an employee of Amazon or Amazon Web Services. All physical and electronic access to data centers by Amazon employees is logged and audited routinely. For additional information see: https://aws.amazon.com/security
Fire Detection and SuppressionAutomatic fire detection and suppression equipment has been installed to reduce risk. The fire detection system utilizes smoke detection sensors in all data center environments, mechanical and electrical infrastructure spaces, chiller rooms and generator equipment rooms. These areas are protected by either wet-pipe, double-interlocked pre-action, or gaseous sprinkler systems.
The data center electrical power systems are designed to be fully redundant and maintainable without impact to operations, 24 hours a day, and seven days a week. Uninterruptible Power Supply (UPS) units provide back-up power in the event of an electrical failure for critical and essential loads in the facility. Data centers use generators to provide backup power for the entire facility.
Climate and Temperature Control
Climate control is required to maintain a constant operating temperature for servers and other hardware, which prevents overheating and reduces the possibility of service outages. Data centers are conditioned to maintain atmospheric conditions at optimal levels. Monitoring systems and data center personnel ensure temperature and humidity are at the appropriate levels.
Data center staff monitor electrical, mechanical and life support systems and equipment so issues are immediately identified. Preventative maintenance is performed to maintain the continued operability of equipment. For additional information see: https://aws.amazon.com/security
Firewalls are utilized to restrict access to systems from external networks and between systems internally. By default all access is denied and only explicitly allowed ports and protocols are allowed based on business need. Each system is assigned to a firewall security group based on the system’s function. Security groups restrict access to only the ports and protocols required for a system’s specific function to mitigate risk.Host-based firewalls restrict customer applications from establishing localhost connections over the loopback network interface to further isolate customer applications. Host-based firewalls also provide the ability to further limit inbound and outbound connections as needed.
Our infrastructure provides DDoS mitigation techniques including TCP Syn cookies and connection rate limiting in addition to maintaining multiple backbone connections and internal bandwidth capacity that exceeds the Internet carrier supplied bandwidth. We work closely with our providers to quickly respond to events and enable advanced DDoS mitigation controls when needed.
Spoofing and Sniffing Protections
Managed firewalls prevent IP, MAC, and ARP spoofing on the network and between virtual hosts to ensure spoofing is not possible. Packet sniffing is prevented by infrastructure including the hypervisor which will not deliver traffic to an interface which it is not addressed to. Chaperone utilizes application isolation, operating system restrictions, and encrypted connections to further ensure risk is mitigated at all levels.
Port scanning is prohibited and every reported instance is investigated by our infrastructure provider. When port scans are detected, they are stopped and access is blocked.
Each tenant on the Chaperone platform runs within its own isolated environment and cannot interact with other applications or areas of the system. This restrictive operating environment is designed to prevent security and stability issues. These self-contained environments isolate processes, memory, and the file system using LXC while host-based firewalls restrict applications from establishing local network connections. Customer data is stored in separate access-controlled databases per application. Each database requires a unique username and password that is only valid for that specific database and is unique to a single application.
System configuration and consistency is maintained through standard, up-to-date images, configuration management software, and by replacing systems with updated deployments. Systems are deployed using up-to-date images that are updated with configuration changes and security updates before deployment. Once deployed, existing systems are decommissioned and replaced with up-to-date systems.
Our vulnerability management process is designed to remediate risks without customer interaction or impact. Chaperone is notified of vulnerabilities through internal and external assessments, system patch monitoring, and third party mailing lists and services. Each vulnerability is reviewed to determine if it is applicable to Chaperone’s environment, ranked based on risk, and assigned to the appropriate team for resolution.
Continuous Protection keeps data safe on Chaperone. Every change to your data is written to write-ahead logs, which are shipped to multi-datacenter, high-durability storage. In the unlikely event of unrecoverable hardware failure, these logs can be automatically 'replayed' to recover the database to within seconds of its last known state. In addition to standard backup practices, Chaperone’s infrastructure is designed to scale and be fault tolerant by automatically replacing failed instances and reducing the likelihood of needing to restore from backup.
The Chaperone platform is designed for stability, scaling, and inherently mitigates common issues that lead to outages while maintaining recovery capabilities. Our platform maintains redundancy to prevent single points of failure, is able to replace failed components, and utilizes multiple data centers designed for resiliency. In the case of an outage, the platform is deployed across multiple data centers using current system images and data is restored from backups. Chaperone reviews platform issues to understand the root cause, impact to customers, and improve the platform and processes.
Access to Customer Data
Chaperone staff does not access or interact with customer data or applications as part of normal operations. There may be cases where Chaperone is requested to interact with customer data or applications at the request of the customer for support purposes or where required by law. Customer data is access controlled and all access by Chaperone staff is accompanied by customer approval or government mandate, reason for access, actions taken by staff, and support start and end time.
To prevent unauthorized account access use a strong passphrase for your Chaperone user account and use Chaperone’s RBAC model to invite contributors rather than sharing user accounts.
