6 Failures to Avoid with SIEM Tools At All Costs

Enterprises lose $4.7 million to cybercriminals annually. Worse, the percentage of enterprises suffering from cybercriminals’ attack tactics increased from 57 percent to 71 percent in 2020.

Furthermore, 56% of IT practitioners say their IT security infrastructure has coverage gaps. This is frequently due to legacy SIEM systems that are unable to scale with enterprise networks. As a result, the first step in solving this problem is to choose a next-generation, use-case-appropriate SIEM solution.

When properly implemented, SIEM is a strong security tool. However, gaining insights and reaping the benefits of using an SIEM tool can be difficult, and many businesses struggle to do so. Unfortunately, if you aren't optimizing the benefit of SIEM, the company can be exposed to a data breach.

In this blog, we share some of the pitfalls to avoid with SIEM tools and how to overcome them.

1. Lack of Goals & Objectives for SIEM Solution

If expectations, goals, and objectives are not defined, the SIEM project will most likely fail. Likewise, the expectations and goals should be in sync, and you'll get buy-in from all stakeholders. All must be on board with the SIEM's deployment and results.

To persuade the leadership team, you must translate the technological benefits into organizational benefits. For the security team, you'll have to choose and share goals that everyone will agree on. Ensure that the security and leadership teams are aware of important project deliverables and milestones.

2. Lack of Training

If you've set aside internal resources to manage and track your new SIEM, make sure your employees get the proper training and growth. SIEM solutions are complex, and if you don't have the right experience, your solution could fail and this could end up being a bad business investment.

Make sure your team is armed with as many questions as possible during the onboarding phase. This will allow them to get the answers they need a lot faster by maximizing onboarding time with the vendor's SIEM specialist.

3. Lack of Security Resources to Manage the SIEM Tool

If you didn't determine the resources needed to handle and control the SIEM during the preparation and coordination process, you might be in trouble. A SIEM system can be a significant investment, and without adequate funding, it can quickly become obsolete.

Having no or insufficient personnel to handle the SIEM is a significant failure for organizations. Your SIEM is unlikely to deliver the results you want if it lacks funding. Many organizations consider controlled SIEM if they don't have enough money at the moment but need to quickly realize the value of SIEM.

4. SIEM Complexity

Collecting logs alone will not increase the value of your SIEM deployment, and it will easily fail. You'll need to transform the log data into useful information. To do so, the team will need to use aggregation, normalization, and correlation to make sense of the logs. To sift through the large volumes of log data and produce consistent security insights, your team will need to set up correlation rules.

One of the most common concerns among security professionals is the inability to remove "noise" from cloud SIEMs. When the SIEM produces a large number of warnings, the security team becomes overwhelmed. This is known as warning fatigue. Since they are constantly bombarded with irrelevant warnings, security analysts are unable to optimize the true value of SIEM in this scenario. SIEMs need fine-tuning and optimization when it comes to log correlation and alerting.

5. Using SIEM Solely for Compliance

SIEM started out as a way to manage enforcement and auditing. However, over time, it has evolved into one of the organization's most centralized security management platforms. If your team is having trouble finding security use cases for your SIEM, you will need to take a closer look at how they can be used.

Malware detection and remediation, brute-force attack handling, authentication tracking, user activity monitoring, security policy monitoring, auditing and executive security reporting are possible with SIEM. Additionally, enforcement monitoring for PCI DSS, HIPAA, SOX, GLBA, GDPR, and other regulations are all possible with SIEM.

6. Not Speeding Up Your Value with SIEM

Your security team is probably looking for answers right now, but your SIEM might be taking far too long to react. Once you've figured out how to reduce the warning "noise," you'll need to add threat intelligence feeds to help with threat detection and response. Integrating threat intelligence feeds into your SIEM raises the bar on defense.

Threat intelligence can be compared to data from your SIEM, and vice versa. Threat intelligence also aids in the refining of the SIEM and the identification of false positive warnings.

7. How to Avoid Security Threats With SIEM?

Integrating threat intelligence with SIEM also allows the security team to hunt down threats ahead of time rather than waiting for logs and sifting through the noise. So what are you waiting for?

If you haven’t already incorporated threat intelligence feeds with your SIEM solution, you’re missing out and not speeding up your time-to-value with the SIEM.
