What is Security Analytics?
Security analytics is a cybersecurity approach that involves the collection, aggregation, and analysis of data to augment an organization’s ability to detect, analyze, manage, and mitigate threats. It is a proactive means of making sense of high volumes of security data flowing in and out of the organization.
Security analytics solutions are usually deployed in organizations to provide rapid threat-hunting capabilities, accelerate incident response, and prevent potentially costly data breaches. They are also used to conduct real-time risk assessments and to enhance an organization’s overall cybersecurity posture.
Why is Security Analytics Important?
Security analytics is important for organizations because it makes it easier to collect large volumes of security data, process, and transform it. In today’s competitive landscape, it is crucial to analyze diverse datasets from multiple sources and identify correlations and anomalies in data.
Security analysis allows experts to conduct root cause investigations and pinpoint various attack patterns. It enables them to generate comprehensive reports and save their findings for future use. Attackers are always on the constant lookout to locate vulnerabilities and exploit them. Security analytics helps disrupt their movement by prioritizing risks and keeping pace with their growing efforts.
How does Security Analytics Work?
Security analytics provides the tools and features needed to investigate incidents, find out how IT systems are compromised, and learn more about emerging threats. It raises the security awareness of an organization by granting deep real-time visibility into its current infrastructure.
No business can know when a threat is incoming, but with security analytics software, organizations can predict the next attack and take appropriate measures. It helps them stay one step ahead of cybercriminals, address hidden and known vulnerabilities, and close identified gaps in security.
There is huge pressure on IT teams to report their latest findings to stakeholders. Security analytics keeps track of threat patterns, monitors movements, and immediately alerts all users in the enterprise once an anomaly is detected.
Who uses Security Analytics?
Almost every modern organization with a digital architecture or presence uses security analytics. Security Operations Centers (SOCs) consist of teams that have analysts, engineers, and other frontline members who use security analytics. CISOs in companies use security analytics solutions to make sure that sensitive data gets adequate protection.
Security analytics is needed by companies because it allows them to detect threats before they escalate, become major issues, and cause data breaches. It is a preventive measure that adds an extra layer of protection, thus ensuring robust cyber security.
Security Analytics vs SIEM
Millions of event and log data are generated on a daily basis and finding the Indicators of Compromise (IoC) can prove to be a huge challenge for enterprises. Security analytics provides full-stack visibility into infrastructures and analyzes mobile, social, information, and cloud-based channels.
SIEM is a great technology that deals with perimeter and signature-based cyber security. It is reflective of today’s dynamic threats. Many organizations choose between SIEM and security analytics and some combine both in an integrated fashion.
Below are the distinct differences between security analytics vs SIEM:
| Security Analytics | SIEM |
| Designed for modern business architectures, dynamic, microservices, and DevOps-friendly; is elastic, multi-tenant, and secure | Designed for monolithic business applications, static, and has long development and release cycles |
| For cloud-based infrastructure; | For on-premises infrastructure |
| Solutions can be deployed instantly and in near real-time | Takes 15 months on average to deploy |
| Uses continuous monitoring methodologies and behavioral-based modeling to protect against unknown and hidden threats. Identifies abstract threat patterns, anomalies, trends, and fraudulent activities in networks. | Delivers perimeter-based security by analyzing attack signatures; has fixed rule sets when it comes to threat detection |
| Holistic and enterprise-wide visibility with APIs, integrations, and cloud-native services | Limited visibility with port mirroring and security islands |
Security Analytics Components
There are various components to security analytics and they are as follows:
- Threat detection and incident response
- Compliance management
- Reports and dashboards
- Correlations and security events monitoring
- Identity and access management
- Anomaly detection
- Endpoint data security
- Data collection and user behavior analytics
- Cloud security and threat intelligence
- Enhanced incident investigation
- Cyber forensic analysis
Most SIEM solutions come with a security analytics component that features live dashboards that intuitively visualize data via graphs and charts. Security teams can update these dashboards automatically, get alerts and notifications, and map data trends and relationships. Another facet of security analytics is the generation of real-time reports. These reports provide enhanced visibility into infrastructure operations and can be customized to fit internal security requirements. They can be exported in different formats and are based on known Indicators of Compromises (IoCs).
Benefits of Security Analytics
- One of the biggest benefits of security analytics is how it can analyze high volumes of security data coming from different sources. It flawlessly connects the dots between security events and alerts. Security analytics enables proactive threat discovery, response, and incident risk management.
- Good security analytics will limit the scope for data breaches by identifying and reducing attack surfaces. It will analyze threats from the attacker’s perspective and give users insights into where the next attack is targeting them. Businesses will be able to predict the frequency of attacks and better prepare for them.
- Security analytics can analyze a broad range of data such as endpoint and user behavior data, network traffic, cloud traffic, business applications, non-IT contextual data, external threat intelligence sources, third-party security data, and identity and access management information. It even provides proof of compliance during an audit and discovers hidden issues that may lead to policy violations, allowing organizations to effectively address them.
What are Some of the Key Challenges of Security Analytics?
Some of the key challenges faced in security analytics are:
1. Shortage of Skilled Security Professionals
Although security analytics technologies are evolving, there is a shortage of skilled security professionals who can use them. In today’s digital threat landscape, the role of a threat hunter has become indispensable. A lack of skilled data scientists in the network security industry is a big problem.
2. Extrapolating Actionable Intelligence
Sometimes security analytics solutions don’t give the best security recommendations. Many services fall short and fail to deliver actionable insights via reporting. Simply handling and categorizing big data isn’t enough.
Many businesses are overwhelmed with the high volumes of data and need to analyze it in ways that benefit their business revenue growth and performance. Without reliable security analytics solutions, organizations will stay open to malicious threats. Security analytics platforms need to be managed properly so that companies know where to invest additional cybersecurity efforts or scale their resources accordingly.
