Security monitoring
Security teams face challenges in effectively monitoring hybrid, cloud, and on-premises technology stacks. To manage these complexities, teams rely on various tools and data sources, continually onboarding new sources for alerts. However, a lack of centralized visibility results in siloed data and blind spots, making it challenging for defenders to detect, investigate, and respond to unseen threats. The absence of customization options for managing alert volumes in the SOC hampers their ability to tailor responses to specific needs.
Additionally, inadequate tooling contributes to a high number of false positives, leading to inefficiencies in incident detection and response. The dependency on third-party applications further increases the vulnerability of the attack surface, exposing the security infrastructure to potential threats. Addressing these issues is crucial for enhancing the overall effectiveness of security teams in safeguarding their organization's digital assets.
What are the benefits of security monitoring?
Effective security monitoring using the Splunk platform, Splunk Security Essentials, and Splunk Enterprise Security produces many benefits that contribute to foundational visibility over your environment:
- Gain comprehensive end-to-end visibility by ingesting data from any source, enabling real-time security monitoring of your environment
- Make data-centric decisions to effectively protect and reduce risk
- Identify the most relevant content (correlations, playbooks, dashboards, etc.) for your organization and the specific threats to your organization
- Use industry standards like MITRE ATT&CK to find the right content and to protect against relevant threats
- Operationalize security use cases and get timely alerts
- Enhance attack surface coverage by including on-premises, hybrid, and multi-cloud environments
- Investigate and analyze with a comprehensive view across all your data sources, facilitating faster detection and response
These benefits contribute to a more robust and proactive security monitoring approach for your organization.
