NetScaler Security Readiness

An ongoing NetScaler update service with proactive CVE monitoring and checks for indications of potential security incidents.

What it means

Deyda Consulting monitors relevant NetScaler security advisories, uses direct communication with Citrix product contacts, and assesses the required action for your environment. Security workarounds and firmware updates supplied by Citrix are prepared and implemented remotely. A service target of implementation within twelve hours after release by Citrix can be agreed. Available indicators are also checked for signs of a potential compromise.

Service components

  • Proactive notification of relevant NetScaler vulnerabilities and CVEs
  • Assessment, preparation and implementation of security workarounds
  • Planning and execution of required NetScaler firmware updates
  • Checks of available Indicators of Compromise and file integrity
  • Documentation of actions, findings and prioritised recommendations

Your benefit

You gain a continuous security and update process instead of isolated measures. A named contact and secure remote access to the NetScaler environment are required. General incident troubleshooting, outages and new functionality are outside the service scope. A clean IoC check cannot conclusively rule out compromise; specialised forensic investigation is required when there is concrete suspicion.

Service framework

Scope, requirements and service delivery

The service starts with a clearly defined operating framework so that security measures and updates can be delivered reliably and without avoidable delays.

Requirements

  • A named technical contact on the customer side
  • Secure remote access with the permissions required for the agreed work
  • Agreed maintenance windows and communication channels
  • Current information about the NetScaler estate, dependencies and backup procedures

Included

  • Continuous monitoring and assessment of relevant NetScaler CVEs
  • Coordination and implementation of required security workarounds
  • Planning and execution of recurring firmware updates
  • Checks of available Indicators of Compromise and file-integrity information
  • Documentation of completed actions, findings and prioritised follow-up tasks

Not included

  • General troubleshooting and remediation of unrelated outages
  • Implementation of new functionality or project-related configuration changes
  • A complete forensic investigation or full incident-response engagement
  • A 24/7 emergency service unless separately agreed

How the recurring service works

  1. 01

    Onboarding, estate inventory and validation of secure access

  2. 02

    Continuous monitoring and technical assessment of relevant advisories

  3. 03

    Coordination and implementation within the agreed maintenance and service framework

  4. 04

Frequently asked questions

Which NetScaler environments is the service suitable for?

The service is designed for production NetScaler ADC and Gateway environments, from individual appliances and HA pairs to estates with multiple instances. The exact scope is agreed after an initial review.

Are firmware updates included?

Yes, depending on the agreed service scope. This can include selecting the target build, checking dependencies, preparing backups and rollback options, carrying out the update and validating the main functions afterwards.

Do you check for signs of compromise or intrusion?

Yes. Available logs, configurations, file-integrity information and known Indicators of Compromise are reviewed for suspicious signs. A clean check cannot conclusively rule out a compromise and does not replace a full forensic investigation.

Which systems and information are reviewed?

The review can include firmware and build levels, saved and running configurations, HA status, certificates and TLS settings, Gateways and published services, relevant system and audit logs, and indicators associated with known vulnerabilities.

What do we receive as the result?

Your NetScaler environment is updated to the agreed target build and required security workarounds are implemented. The completed changes, validation results and final technical status are documented within the agreed scope.

What happens if a critical finding is identified?

Critical findings are documented and discussed with the customer. The required follow-up tasks and recommended next steps are then provided in a clear and prioritised form.

How does this differ from the NetScaler Firmware Update Service?

The Firmware Update Service is a one-off, planned technical update. NetScaler Security Readiness is the recurring service: it continuously monitors relevant CVEs, coordinates updates and security workarounds, and performs regular checks for security-relevant findings.

Is NetScaler Security Readiness a recurring service?

Yes. NetScaler Security Readiness is a recurring update and security service with proactive CVE monitoring, coordinated updates and regular checks for security-relevant findings. It cannot be booked as a one-off service.
