At Xenett, the security of your data is our highest priority. Security is our key component in our offering and reflected in our people, process, and product. This page covers topics like data security, operation security, and physical security to explain how we offer security to our customers.
1. Secure by design
Every change and new feature is governed by a change management policy to ensure all application changes are authorized 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 analyzer tools, vulnerability scanners, and manual review processes.
Our robust security framework based on OWASP standards, implemented in the application layer, provides functionalities to mitigate threats such as SQL injection, Cross site scripting and application layer DOS attacks.
2. Modern, Secure Infrastructure
Modern, secure infrastructure Our application is hosted and served through Amazon Web Services. These platforms are certified under various ISO and SOC compliance standards as detailed here https://aws.amazon.com/security/ . All data is hosted in these providers in US-based data centers.
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, 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 services 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 ensures 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.
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.
1. Logging and Monitoring
We monitor and analyses 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.
2. 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.
3. Malware and spam protection
We scan all user files using our automated scanning system that’s designed to stop malware from being spread. 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.
4. Disaster recovery and business continuity
Application data is stored on resilient storage that is replicated across multiple regions of AWS. Data in the primary AZ is replicated in the secondary in near real time. In case of failure of the primary AZ, secondary AZ takes over and the operations are carried on smoothly with minimal or no loss of time.
We have power back-up, temperature control systems and fire-prevention systems as physical measures to ensure business continuity. These measures help us achieve resilience. In addition to the redundancy of data, we have a business continuity plan for our major operations such as support and infrastructure management.
1. At Workplace
We control access to our resources (buildings, infrastructure and facilities), where accessing includes consumption, entry, and utilization, with the help of biometric system. 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.
We monitor all entry and exit movements throughout our premises in all our business 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.
1. Security Awareness
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.
2. Dedicate security and privacy terms
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.
3. Endpoint security
All workstations issued to our employees run up-to-date OS version and are configured with anti-virus software. They are configured such that they comply with our standards for security, which require all workstations to be properly configured, patched, and be tracked and monitored by our endpoint management solutions. These workstations are secure by default as they are configured to encrypt data at rest, have strong passwords, and get locked when they are idle.
