Every organization should have effective security management as an imperative part. In that case, the managed SIEM can be an effective option as it extends the IT part and adds the most essential key cyber skills to find the security threats. The managed security not only improves the security posture but also makes your staff concentrate on their own task. Here, we will discuss everything about SIEM and its part-managed SIEM solution. So let’s have a look.
What Is SIEM?
SIEM stands for Security Information and Event Management. It combines integrated and monitoring tools that detect if any organization is going to have an attack. It works by analyzing log information from any device, infrastructure or system to target suspicious activities inside the system and device network. If they find anything suspicious there, they send an alert for further investigation.
As the IT estate always has security breach threats, there is a need for complete threat management. When this is a matter of SIEM, it may look quite confusing from the start. The SIEM is essential for those who want to get better at managing security incidents or to aggregate the way they respond to security breaches.
Let’s read the full article. Here the SIEM is discussed thoroughly. Hope you will understand everything here and can find the answer to ‘ Whether SIEM works for me’?.
How Does SIEM Work?
SIEM software first collects logs from devices, systems, and infrastructure. After that, it analyzes the data and provides a detailed view of the information technology of the same organization. The SIEM solution can work from on-premises or any cloud environment. It uses the SIEM methods, rules, and statistical correlations during its investigation in the system.
If anything doubtful happens, SIEM divides it into different categories. Examples of those categories include malware activities, failed login, and unsuccessful login, etc. Using the predefined rules, the security issue alert can be set as a low or high priority.
As an example, if there are 20 failed login attempts in 20 minutes, it will be suspicious. But it will be shown as low priority as it indicates the user may have forgotten the login details. In that case, if there are 120 failed login attempts in 5 minutes, then this will be shown as a brute force attack.
Types Of SIEM
The different types of SIEM are dependent upon company need, capacity to invest, the maturity level of the internal security system. Here different SIEM solutions are explained below:
- In-house SIEM
The in-house SIEM poses ultimate control in the security system. It needs specific software and hardware as an implementation. In that case, the organization can customize the in-house SIEM as per the regular updates. In in-house SIEM, a third party is not involved and the information doesn’t go outhouse or stays in the house. However, the In-house SIEM needs high investment, the standard cost of maintenance, etc.
- Cloud-based SIEM
As per the increased demand for cloud-adopted technology, the popularity of Cloud-based SIEM has gained clarity. The cloud-based SIEM system is subscription-based but requires a minimal cost. It allows the user to invest on a monthly or annual subscription rather than any significant amount. In the closed-based technology of SIEM, the customer can control the security system. However, few of the users reported the full potential of SIEM may not be available.
- Managed SIEM
The managed SIEM involves both in-house SIEM and cloud-based SIEM. The managed SIEM is generally hosted by the vendor’s server to monitor their client security system. There are many reasons for taking managed SIEM including first deployment, flexible cost, easy maintenance, etc.
Choosing the right SIEM system for any organization is crucial. There are 3 main parts of SIEM solutions. The managed SIEM is an atheist popular and effective among them. Let’s know the details about it.
Why Choose Managed SIEM System
There are several reasons for choosing a managed SIEM solution. The managed SIEM leaves a contribution to the overall security posture of any organization resulting in better compliance requirements and in improving MTTD and MTTR.
( MTTD stands for Mean Time To Detect. MTTR stands for Mean Time To Response).
If you are considering SIEM security solutions for your organization, then consider these 3 reasons for choosing Managed SIEM solutions.
- Lack Of Resources: SIEM solutions require enough resources or security personnel to set up, customize and monitor their security alerts. But the small IT firms must be dealing with the IT issues in their organisation. In that case, they may not have enough time to. monitor the security activities and respond to them individually.
But the managed SIEM scans the security network of the company and addresses their weak points that give result breach less operation for a long time.
- Lack of Time: A complex SIEM takes a lot of time. Every SIEM product is different. In that case, the professional needs to evaluate them and need entire data or weeks on learning about using them. The cybersecurity professional needs to give labour time on monitoring logs and investigating threats as most of the SIEM can’t do it.
In that case, the managed SIEM does behavioral monitoring to fund unusual activities at the same time. It helps in eliminating the raised security issues within a short time.
- Lack Of Budget: Hiring IT professionals for monitoring the security network is expensive. Some of the largest companies can only bring the In-house SIEM option. In that case, the managed SIEM solution can be a great option rather than paying some full-timeline salary for the same job.
In that case, you should know that the managed SIEM services have dedicated assistance who spend their time for multiple clients. Oftentimes, they take action to give you protection from unwanted security issues.
