Security Information & Event Management

Experienced Cybersecurity Analysts

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.

Vigilant

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.

Responsive

Improve remediation and incident response times to reduce exposure from reconnaissance, lateral movement on the network and data exfiltration.

Managed

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.

SIEM Highlights

Reduce Dwell Time

  • Reduce exposure to existing threats
  • More than just a metric – take a positive step towards a mature security posture

Improve Mean Time to Detect (MTTD)

  • Lower the cost of cyber security incidents
  • Reduce the risk of prolonged dwell times
  • Improve operational availability
  • Identify areas of weakness/compromise

Reduce Mean Time to Respond (MTTR)

  • Reduces exposure
  • Improves operational efficiencies
  • Lowers the cost of clean-up & remediation

FREQUENTLY ASKED QUESTIONS (FAQS)

What is SIEM?

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.

How does SIEM work, and why is it important?

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.

What are the key features of a SIEM?

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.

Event Correlation
Matching multiple events to indicate specific incidents.

What is a security event?

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.

What is the best practice for a successful SIEM implementation?

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.
