With an ever-growing attack surface and the barrier to becoming a threat actor lowering, volumes of malicious actions continue to increase. This makes it more challenging than ever before for defenders to identify, triage and address threats.
A team of experienced cybersecurity analysts is combined with a best-in-class SIEM to deliver a managed service that helps organisations cut through vast datasets and focus on activities necessary to reduce risk. This reduces dwell time and improves response times to security incidents.
Identify and prioritise security threats more effectively to ensure the most efficient application of security resources while also reducing risk. A continual reduction in detection time is a good marker of security maturity.
Improve remediation and incident response times to reduce exposure from reconnaissance, lateral movement on the network and data exfiltration.
24 x 7 security information and event management (SIEM) and incident response handled by an experienced team, allowing the security function to focus on strategy.
Security Information and Event Management (SIEM) provides organisations with combined security information management/ (SIM) with security event management (SEM) to provide a consolidated view of threats.
A SIEM works by collecting and logging event data produced by an organisation’s applications, host systems and security devices in a single centralised platform. SIEM gathers log data from firewalls, antivirus, and other sources and presents analysts with event context.
SIEM solutions are essential for consolidating an otherwise unmanageable volume of threat data, filtering information and prioritising alerts to make security more manageable. Apart from this primary use case of logging and log management, enterprises also use their SIEM for compliance requirements with ISO27001, HIPAA, PCI, DSS, SOX, and GDPR.
Data consolidation/ Data aggregation
Managing log events and data in real time from different sources and categorising them by severity using threat intelligence to determine actions.
Automated security event alerts
Analysing indicators of compromise and sending alerts to notify of issues in real-time.
Visibility in near-real time
Dashboards provide an overall view of the security environment.
Matching multiple events to indicate specific incidents.
A security event is anything that has an implication for the security team. Organisations may experience thousands each day, from malicious emails and automated scanning to attempted exploitation.
Establish scope and requirements
An organisation should know what log and event data they want the SIEM to monitor, understanding whether it should be hosted/managed or on-premises. Having a clear view of compliance and regulation requirements is also essential.
Customise correlation rules
A SIEM’s core value stems from event correlation to understand and prioritise events that may otherwise go unnoticed. Most come with a set of in-built rules that can be customised.
Have an incident response plan set
A SIEM provides real-time monitoring and enterprise security alerts to allow for a timely response if a threat is detected. An efficient incident response plan provides guidelines and steps for security teams to follow when there is an attack.
Update your SIEM system continuously
Refine the configuration and optimise correlation rules, policies and procedures to stay ahead of malicious attackers.
