For public sector organizations, the creation of a Security Operations Centre (SOC) is not a one-off temporary solution; rather it is a long-term cybersecurity journey. Threats are continually changing, security technologies must be continually tuned for success, and infrastructure needs to be continually adjusted for operation. Even if a SOC is created to handle rigorous security standards, it can become less effective over time if not maintained on an ongoing basis.
This is why proactive managed support is a must. After deployment, Trident Techlabs continues to support organizations in the public sector with keeping their SOC environment responsive, updated and in line with the evolving cybersecurity landscape.
Resilience Begins After Deployment
A new SOC can combine SIEM systems, security technologies, network technologies, and sources of threat intelligence. But these components must be continually optimized to have any real impact.
As organizational environments change, normal user behavior, network traffic and application activity also change. Security systems can be over-alerting or missing alarms if not monitored and tuned regularly.
This is where the post-deployment support comes into play in solving such challenges through continuous surveillance of the effectiveness of the SOC in the real-world environment.
Fine-tuning SIEM Correlation for improved detection
SIEM correlation rules are a critical component in establishing connections between security events. But the rules that have worked well during initial deployment can be adjusted as the infrastructure and attack patterns change over time.
Trident Techlabs supports security teams to fine-tune SIEM correlation rules in Multi-OEM environments. This includes the ability to tweak detection logic, modify thresholds and enhance event correlation to minimize unnecessary alerts, whilst still keeping a clear view of suspicious activity.
The goal isn’t just to get more alerts. It’s to provide security analysts with alerts that are more relevant and have more contexts for action.
Transforming Threat Intelligence into reality
Threat intelligence is useful when it can be integrated into the organization’s security monitoring. New indicators, attack techniques and emerging threats can change the way security teams need to interpret events.
Organizations can enhance their skills to detect activity related to known threats by leveraging relevant threat intelligence in their SOC workflows. This can provide an additional context to SIEM events and assist analysts in more quickly probing into potential malicious activity.
In the public sector, where information is often sensitive and operations are important, it is essential to continuously refresh this knowledge in order to remain resilient.
Maintaining Multi-OEM Environments up-to-date
Typically, a public sector SOC will have several different technologies in use from various vendors. These environments cannot be maintained with only an indication of the running of individual platforms.
Security platforms must be upgraded, integrations adjusted and compatibility retained when there are changes in components. Trident Techlabs offers continuous support to ensure organizations are able to manage their platform upgrades and the effectiveness of interdependent security technologies.
This also enables organizations to not view cybersecurity as a project to be implemented once and done.
A continuous cycle of improvement
There is a SOC management lifecycle: monitor, analyze, tune, update and improve. The information from each stage can enhance the subsequent stage.
Managed support enables security teams to discover performance shortcomings, fine-tune detection, add new intelligence and ensure security platforms remain current with the operational demands. As this ongoing enhancement is implemented, it can help mitigate alert fatigue and enhance the organization’s ability to address new threats.
How to develop a long-term cyber resilience strategy?
Cybersecurity resiliency must be more than just what’s included on day one in public sector organizations. That technology has to be maintained and adapted over the life of the technology in an effective way.
Trident Techlabs’ deployment capabilities are complemented by the ability to provide managed support services—helping public sector SOCs stay operationally effective. Whether it’s tuning SIEM, integrating threat intelligence or coordinating with Multi-OEMs or platform upgrades, security teams are sure to be able to stay ahead of the threat curve.
Resilient SOC is not a complete system. It’s a constantly evolving security capability that is designed to outpace threats it’s meant to identify.
