When it comes to ensuring the confidentiality, integrity, and availability of an organization’s critical data and information such as personally identifiable information (PII), banking data, company secrets, and more, your SOC is the main line of defense The cloud-based SOC tool helps act as a line of much-needed defense against possible cybersecurity threats so you can better optimize your cybersecurity.
Optimize SIEM Technology to Avoid Redundancy
SIEM (security information and event management) is a technology that aggregates and analyzes data from various sources across your IT infrastructure.
SIEM technology is a critical part of any robust cybersecurity operation, but to remain relevant, it requires proper implementation and continuous maintenance to maximize effectiveness. At the same time, most SMBs have limited cybersecurity budgets and don’t have enough in-house security professionals. Nevertheless, implementing a SOC equipped with a regularly maintained SIEM can save you countless hours and maintain business focus.
SIEM Optimization and Tuning
The SIEM has two primary functions that are relevant for your SOC: reporting and forensic information about security incidents, and generating alerts based on correlations and algorithms that were written to detect various set rules, which would indicate a security event.
SIEM tuning is the process of filtering all the data that is being received to identify cybersecurity risks, system failures or anomalies, compliance, and more. This should be done as part of the initial setup process for your SIEM. Tuning a SIEM to your organization very specific, because each organization’s needs, activities, behaviors, and assets are different. In this way, you will get the best value from your SIEM. It’s very important not to overlook asset categorization and network hierarchy configurations, which are commonly forgotten. Essentially what you’re doing by configuring your SIEMis setting up a process to avoid rules that constantly trigger false positives.
With a SIEM as part of your SOC, it’s crucial that it is properly tuned to your specific business’s needs, otherwise, the SIEM will not detect security incidents that can put your business at risk. Additionally, tuning is not a one-time process done during initial set-up. To maximize your investment, and best protect your business and assets, your SIEM should be regularly optimized and tuned to stay up to date with the latest IOCs, TTPs, and threat intelligence.
Companies, both large and small, invest a lot of time and resources to detect, collect, normalize, log, load, and index big data for multiple security purposes; this process tends to create redundancy.
A good SOC backed with AI can help you avoid redundancy by providing you with easy-to-understand data concerning potential threats. An AI should be able to gather the data needed to ensure your success with threat hunting and early detection. The information provided by the AI can save you time because you don’t have to analyze large amounts of data to address the potential threat.
Optimization with Artificial Intelligence (AI)
By using AI capabilities, your SOC can manage billions of datasets from both structured and unstructured sources. In addition, it can find connections between cybersecurity threats such as malicious IP addresses and other suspicious files, which will automatically cause a red flag alert.
AI should be able to generate behavioral analysis to accurately detect threats. Signature-based techniques are less effective against rapidly growing cybersecurity threats, especially boot-record and ransomware attacks. AI effectively identifies risky behavior that might lead to phishing attacks or lure your corporate employees into downloading a malicious attachment.
Harden Your Cybersecurity Posture with Cyber Professionals
When it comes to maintaining and optimizing your SIEM, it’s important to have cybersecurity experts on hand. If you lack the expertise in-house that is required to constantly maintain and optimize your SIEM, it’s recommended to seek outside help to manage it. After a few months without maintenance, the SIEM technology can already start to be outdated, since it hasn’t been updated with new rules and correlations based on the ever-changing cyber threats.
