Independence of resources Customer environments are logically segregated to prevent users and customers from accessing resources not assigned to them.

Services which provide virtualized operational environments to customers (i.e. EC2) ensure that customers are segregated via security management processes/controls at the network and hypervisor level.

AWS continuously monitors service usage to project infrastructure needs to support availability commitments/requirements. AWS maintains a capacity planning model to assess infrastructure usage and demands at least monthly, and usually more frequently. In addition, the AWS capacity planning model supports the planning of future demands to acquire and implement additional resources based upon current resources and forecasted requirements.

Other data at rest protection approach AWS adheres to independently validated privacy, data protection, security protections and control processes. (Listed under “certifications”).

AWS is responsible for the security of the cloud; customers are responsible for security in the cloud. AWS enables customers to control their content (where it will be stored, how it will be secured in transit or at rest, how access to their AWS environment will be managed).

Wherever appropriate, AWS offers customers options to add additional security layers to data at rest, via scalable and efficient encryption features. AWS offers flexible key management options and dedicated hardware-based cryptographic key storage.

Availability and resilience

Availability and resilience
Guaranteed availability AWS currently provides SLAs for several services. Due to the rapidly evolving nature of AWS’s product offerings, SLAs are best reviewed directly on AWS' website via the links below:

• Amazon EC2 SLA: http://aws.amazon.com/ec2-sla/
• Amazon S3 SLA: http://aws.amazon.com/s3-sla
• Amazon CloudFront SLA: http://aws.amazon.com/cloudfront/sla/
• Amazon Route 53 SLA: http://aws.amazon.com/route53/sla/
• Amazon RDS SLA: http://aws.amazon.com/rds-sla/
• AWS Shield Advanced SLA: https://aws.amazon.com/shield/sla/

Well-architected solutions on AWS that leverage AWS Service SLA’s and unique AWS capabilities such as multiple Availability Zones, can ease the burden of achieving specific SLA requirements.
Approach to resilience This is available on request.
Outage reporting Public dashboard; personalised dashboard with API and events; configurable alerting (email / SMS / messaging)

Identity and authentication

Identity and authentication
User authentication
  • 2-factor authentication
  • Identity federation with existing provider (for example Google apps)
  • Limited access network (for example PSN)
  • Dedicated link (for example VPN)
  • Username or password
  • Other
Other user authentication WS controls access via unique user ID/password authentication. No actions are permissible without authentication. Remote access is multi-factor, login attempts are limited, remote administrative access attempts are logged and reviewed by Security. Suspicious activity initiates incident response procedures.

A session lock out policy that is systematically enforced: locks are retained until identification/authentication procedures are concluded.

AWS’s Identity and Access Management (IAM) system controls access to AWS services/resources. IAM facilitates the issuance of access permissions per user/group. MFA is available at no extra cost.
Access restrictions in management interfaces and support channels IAM provides user access control to AWS services, APIs and specific resources. Other controls include time, originating IP address, SSL use, and whether users authenticated via MFA devices.

API calls to launch/terminate instances, change firewalls, and perform other functions are signed by customers’ Amazon Secret Access Key (either the root AWS Account’s Secret Access Key or the Secret Access key of a user created with AWS IAM). Amazon EC2 API calls cannot be made on customers’ behalf without access to customers’ Secret Access Ke.

API calls can be encrypted with TLS/SSL for confidentiality and customers can use TLS/SSL-protected API endpoints.
Access restriction testing frequency At least every 6 months
Management access authentication 2-factor authentication
Devices users manage the service through Dedicated device on a segregated network (providers own provision)

Information security policies and processes Ensono maintains certification to ISO/IEC 27001:2013 as its approach to Information Security Management as part of Information Security Management System (ISMS). As part of the ISMS, Ensono shall:
•Define and maintain an inventory of all information assets, and supporting assets, which the security of the information assets depend
•Perform regular risk assessments of those information assets, and their supporting assets, to ascertain level of business risk, as per the Ensono Risk Assessment Guide
•Put in place controls to reduce identified risks to acceptable levels, taking account the criticality and value of information and costs involved, as per the Ensono Risk Assessment Guide
•Provide a rolling education programme to all personnel within Ensono, covering importance of information security, and individuals responsibility to adhere to information security related policies, processes and procedures.
•Provide a tool for the prompt reporting of actual or potential security incidents, and resources to promptly evaluate and act upon such incidents
•Continually monitor, review and improve ISMS by undertaking regular reviews, audits and other activities, and take prompt action in response to the findings
•Adopt ISO/IEC 27001:2013 as the approach to Information Security Management, and utilise the Control Objectives of ISO/IEC 27002:2013 for controlling risk

Operational security

Operational security
Configuration and change management standard Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Configuration and change management approach The objective of Change Management is to ensure that changes are recorded, evaluated, authorised, prioritised, planned, tested, implemented, documented and reviewed in a controlled manner, utilising the ITIL framework to ensure good practice.

To minimise the risk of impact of change related incidents and to record and communicate the changes that are made
Vulnerability management type Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Vulnerability management approach Vulnerabilities are identified using Ensono’s Vulnerability Assessment Tool, which collects and collates data from trusted external sources (e.g. Secunia). These are reviewed by a Subject Matter Expert and assigned a patch rating (Critical, High, Medium, Low, or Not Applicable). An Emergency Vulnerability Assessment Board (VAB) is convened immediately to discuss Critical risk vulnerabilities, otherwise VAB meets on a monthly basis. Affected Clients are identified and a summary of the vulnerability is sent to these Clients. Out-of-band patching schedules may be created for critical vulnerabilities; high, medium and low risk vulnerabilities will be rolled into the quarterly patching cycle.
Protective monitoring type Conforms to a recognised standard, for example CSA CCM v3.0 or SSAE-16 / ISAE 3402
Protective monitoring approach •File integrity monitoring, alerting and incident resolution - The pre-configured FIM report show any file changes on a daily basis
•Registry integrity monitoring, alerting and incident resolution - as part of default monitoring.
•Security log alerting from security appliances and incident resolution - Ensono create alerts and incident resolution.
•Behaviour anomaly detection, investigation and incident resolution through manual report assessment.
•Alerting - Ensono create alerts and incident resolution.
SIEM is vastly used within ‘Ensono Management Environment’ If Client has subscribed to Log Management (SIEM) services then all the mentioned alerting and more can be provided to client.
Incident management type Conforms to a recognised standard, for example, CSA CCM v3.0 or ISO/IEC 27035:2011 or SSAE-16 / ISAE 3402
Incident management approach Ensono has a predefined Incident Management process, which includes activities from incident notification and logging, classification and escalation, investigation and diagnosis, through to resolution, recovery and incident closure. Ensono’s standard approach is at a VM level is primarily agent based through NetIQ, which reports back to our monitoring platform. This includes many standard metrics including, CPU, Memory, Disk. For all of these there are standard thresholds configured which can be changed on client request. If any of these was to exceed these thresholds for a certain amount of time then a ticket would automatically be raised in support works system.

Secure development

Secure development
Approach to secure software development best practice Independent review of processes (for example CESG CPA Build Standard, ISO/IEC 27034, ISO/IEC 27001 or CSA CCM v3.0)

Separation between users

Separation between users
Virtualisation technology used to keep applications and users sharing the same infrastructure apart Yes
Who implements virtualisation Supplier
Virtualisation technologies used Other
Other virtualisation technology used AWS proprietary
How shared infrastructure is kept separate Customer environments are logically segregated, preventing users and customers from accessing unassigned resources. Customers maintain full control over their data access. Services which provide virtualized operational environments to customers, ensure that customers are segregated and prevent cross-tenant privilege escalation and information disclosure via hypervisors and instance isolation.
