We have an Information Security Management System (ISMS) in place which takes into account our security objectives and the risks and mitigations concerning all the interested parties. We employ strict policies and procedures encompassing the security, availability, processing, integrity, and confidentiality of customer data.
Employee background checks
Each employee undergoes a process of background verification. We hire reputed external agencies to perform this check on our behalf. We do this to verify their criminal records, previous employment records if any, and educational background. Until this check is performed, the employee is not assigned tasks that may pose risks to users.
Each employee, when inducted, signs a confidentiality agreement and acceptable use policy, after which they undergo training in information security, privacy, and compliance. Furthermore, we evaluate their understanding through tests and quizzes to determine which topics they need further training in. We provide training on specific aspects of security, that they may require based on their roles.
We educate our employees continually on information security, privacy, and compliance in our internal community where our employees check in regularly, to keep them updated regarding the security practices of the organization. We also host internal events to raise awareness and drive innovation in security and privacy.
Dedicated security and privacy teams
We have dedicated security and privacy teams that implement and manage our security and privacy programs. They engineer and maintain our defense systems, develop review processes for security, and constantly monitor our networks to detect suspicious activity. They provide domain-specific consulting services and guidance to our engineering teams.
Internal audit and compliance
We have a dedicated compliance team to review procedures and policies in Steema to align them with standards, and to determine what controls, processes, and systems are needed to meet the standards. This team also does periodic internal audits and facilitates independent audits and assessments by third parties.
At workplace: We control access to our resources (buildings, infrastructure and facilities), where accessing includes consumption, entry, and utilization, with the help of access cards. We provide employees, contractors, vendors, and visitors with different access cards that only allow access strictly specific to the purpose of their entrance into the premises. Human Resource (HR) team establishes and maintains the purposes specific to roles. We maintain access logs to spot and address anomalies.
Monitoring: We monitor all entry and exit movements throughout our premises in all our business centers and data centers through CCTV cameras deployed according to local regulations. Back-up footage is available up to a certain period, depending on the requirements for that location.
Network security: Our network security and monitoring techniques are designed to provide multiple layers of protection and defense. We use firewalls to prevent our network from unauthorized access and undesirable traffic. Our systems are segmented into separate networks to protect sensitive data.
We monitor firewall access with a strict, regular schedule. A network engineer reviews all changes made to the firewall every day. Additionally, these changes are reviewed every three months to update and revise the rules. Our dedicated Network Operations Center team monitors the infrastructure and applications for any discrepancies or suspicious activities. All crucial parameters are continuously monitored using our proprietary tool and notifications are triggered in any instance of abnormal or suspicious activities in our production environment.
Network redundancy: All the components of our platform are redundant. We use a distributed grid architecture to shield our system and services from the effects of possible server failures. If there’s a server failure, users can carry on as usual because their data and Steema services will still be available to them.
We additionally use multiple switches, routers, and security gateways to ensure device-level redundancy. This prevents single-point failures in the internal network.
Server hardening: All servers provisioned for development and testing activities are hardened (by disabling unused ports and accounts, removing default passwords, etc.). The base Operating System (OS) image has server hardening built into it, and this OS image is provisioned in the servers, to ensure consistency across servers.
Intrusion detection and prevention: Our intrusion detection mechanism takes note of host-based signals on individual devices and network-based signals from monitoring points within our servers. Administrative access, use of privileged commands, and system calls on all servers in our production network are logged. Rules and machine intelligence built on top of this data give security engineers warnings of possible incidents. At the application layer, we have our proprietary WAF which operates on both white list and blacklist rules.
At the Internet Service Providers (ISP) level, a multi-layered security approach is implemented with scrubbing, network routing, rate limiting, and filtering to handle attacks from network layer to application layer. This system provides clean traffic, reliable proxy service, and a prompt reporting of attacks, if any.
Secure by design: Every change and new feature is governed by a change management policy to ensure all application changes are authorised before implementation into production. Our Software Development Life Cycle (SDLC) mandates adherence to secure coding guidelines, as well as screening of code changes for potential security issues with our code analyser tools, vulnerability scanners, and manual review processes.
Data isolation: Our framework distributes and maintains the cloud space for our customers. Each customer’s service data is logically separated from other customers’ data using a set of secure protocols in the framework. This ensures that no customer’s service data becomes accessible to another customer.
The service data is stored on our servers when you use our services. Your data is owned by you, and not by Steema. We do not share this data with any third-party without your consent.
Encryption In transit: All customer data transmitted to our servers over public networks is protected using strong encryption protocols. We mandate all connections to our servers use Transport Layer Security (TLS 1.2/1.3) encryption with strong ciphers, for all connections including web access, API access, our mobile apps, and IMAP/POP/SMTP email client access. This ensures a secure connection by allowing the authentication of both parties involved in the connection, and by encrypting data to be transferred. Additionally for email, our service leverages opportunistic TLS by default. TLS encrypts and delivers email securely, mitigating eavesdropping between mail servers where peer services support this protocol.
We have full support for Perfect Forward Secrecy (PFS) with our encrypted connections, which ensure that even if we were somehow compromised in the future, no previous communication could be decrypted. We have enabled HTTP Strict Transport Security header (HSTS) to all our web connections. This tells all modern browsers to only connect to us over an encrypted connection, even if you type a URL to an insecure page at our site. Additionally, on the web we flag all our authentication cookies as secure.
Encryption At rest: Sensitive customer data at rest is encrypted using 256-bit Advanced Encryption Standard (AES). The data that is encrypted at rest varies with the services you opt for. We own and maintain the keys using our in-house Key Management Service (KMS). We provide additional layers of security by encrypting the data encryption keys using master keys. The master keys and data encryption keys are physically separated and stored in different servers with limited access.
Data retention and disposal: We hold the data in your account as long as you choose to use Steema Services. Once you terminate your Steema user account, your data will get deleted from the active database during the next clean-up that occurs once every 6 months. The data deleted from the active database will be deleted from backups after 3 months. In case of your unpaid account being inactive for a continuous period of 120 days, we will terminate it after giving you prior notice and option to back-up your data.
Identity and Access control
Multi-Factor Authentication: It provides an extra layer of security by demanding an additional verification that the user must possess, in addition to the password. This can greatly reduce the risk of unauthorized access if a user’s password is compromised. You can configure multi-factor authentication using Steema One-Auth. Currently, different modes like biometric, Push Notification, and Time-based OTP are supported.
Administrative access: We employ technical access controls and internal policies to prohibit employees from arbitrarily accessing user data. We adhere to the principles of least privilege and role-based permissions to minimize the risk of data exposure.
Access to production environments is maintained by a central directory and authenticated using a combination of strong passwords, two-factor authentication, and passphrase-protected SSH keys. Furthermore, we facilitate such access through a separate network with stricter rules and hardened devices. Additionally, we log all the operations and audit them periodically.
Logging and Monitoring: We monitor and analyse information gathered from services, internal traffic in our network, and usage of devices and terminals. We record this information in the form of event logs, audit logs, fault logs, administrator logs, and operator logs. These logs are automatically monitored and analyzed to a reasonable extent that helps us identify anomalies such as unusual activity in employees’ accounts or attempts to access customer data. We store these logs in a secure server isolated from full system access, to manage access control centrally and ensure availability.
Detailed audit logging covering all update and delete operations performed by the user are available to the customers in every Steema service.
Vulnerability management: We have a dedicated vulnerability management process that actively scans for security threats using a combination of certified third-party scanning tools and in-house tools, and with automated and manual penetration testing efforts. Furthermore, our security team actively reviews inbound security reports and monitors public mailing lists, blog posts, and wikis to spot security incidents that might affect the company’s infrastructure.
Once we identify a vulnerability requiring remediation, it is logged, prioritized according to the severity, and assigned to an owner. We further identify the associated risks and track the vulnerability until it is closed by either patching the vulnerable systems or applying relevant controls.
Malware and spam protection: We scan all user files using our automated scanning system that’s designed to stop malware from being spread through Steema’s ecosystem. Our custom anti-malware engine receives regular updates from external threat intelligence sources and scans files against blacklisted signatures and malicious patterns. Furthermore, our proprietary detection engine bundled with machine learning techniques, ensures customer data is protected from malware.
Backup: We run incremental backups everyday and weekly full backups of our databases. We store them in tar.gz format. All backed up data are retained for a period of three months. If a customer requests for data recovery within the retention period, we will restore their data and provide secure access to it. The timeline for data restoration depends on the size of the data and the complexity involved.
To ensure the safety of the backed-up data, we use a redundant array of independent disks (RAID) in the backup servers. All backups are scheduled and tracked regularly. In case of a failure, a re-run is initiated and is fixed immediately. The integrity and validation checks of the full backups are done automatically by the ZAC tool.
From your end, we strongly recommend scheduling regular backups of your data by exporting them from the respective Steema services and storing it locally in your infrastructure.
Reporting: We have a dedicated incident management team. We notify you of the incidents in our environment that apply to you, along with suitable actions that you may need to take. We track and close the incidents with appropriate corrective actions. Whenever applicable, we will identify, collect, acquire and provide you with necessary evidence in the form of application and audit logs regarding incidents that apply to you. Furthermore, we implement controls to prevent recurrence of similar situations.
We respond to the security or privacy incidents you report to us through firstname.lastname@example.org, with high priority. For general incidents, we will notify users through our blogs, forums, and social media. For incidents specific to an individual user or an organization, we will notify the concerned party through email (using their primary email address of the Organisation administrator registered with us).
Vendor and Third-party supplier management: We evaluate and qualify our vendors based on our vendor management policy. We onboard new vendors after understanding their processes for delivering us service, and performing risk assessments. We take appropriate steps to ensure our security stance is maintained by establishing agreements that require the vendors to adhere to confidentiality, availability, and integrity commitments we have made to our customers. We monitor the effective operation of the organization’s process and security measures by conducting periodic reviews of their controls.
Customer controls for security: So far, we have discussed what we do to offer security on various fronts to our customers. Here are the things that you as a customer can do to ensure security from your end:
— Choose a unique, strong password and protect it.
— Use multi-factor authentication.
— Use the latest browser versions, mobile OS and updated mobile applications to ensure they are patched against vulnerabilities and to use latest security features.
— Exercise reasonable precautions while sharing data from our cloud environment.
— Classify your information into personal or sensitive and label them accordingly.
— Monitor devices linked to your account, active web sessions, and third-party access to spot anomalies in activities on your account, and manage roles and privileges to your account.
— Be aware of phishing and malware threats by looking out for unfamiliar emails, websites, and links that may exploit your sensitive information by impersonating Steema or other services you trust.
