Introduction
Buying a SIEM solution is a daunting task and to this, ensuring a successful deployment and functioning of the SIEM is even more challenging. While we come across plenty of buyer’s guides that talk about choosing the right SIEM solution, what they really do not talk about is the common implementation mistakes to avoid that a SOC team often commits during the deployment phase. While buying the right SIEM solution is important, also ensuring that the SIEM is appropriately deployed and functioning well is all the more crucial.
Sharing some useful and interesting tips we have today in this blog shared some common mistakes committed during the implementation process. In this blog post, we'll discuss 9 of the most critical mistakes that a CISO might make when choosing a SIEM solution, including both technical and non-technical considerations.
9 Common Mistakes When Implementing SIEM
1. Poor Evaluation of SIEM Capabilities
It is important to thoroughly evaluate the capabilities of a SIEM solution before making a purchase. This includes testing the solution's performance and scalability, as well as its ability to integrate with existing systems and processes. This is crucial for ensuring the successful implementation of SIEM.
For example, if an organization uses a particular type of firewall or intrusion detection system, it will be important for the SIEM solution to be able to collect and analyze data from these devices in order to provide the desired output and offer a comprehensive view of the organization's security posture.
If a CISO fails to fully evaluate the SIEM solution's capabilities in this regard and other such similar aspects as well, it may be unable to effectively collect and analyze data from these devices, leading to reduced performance and potential security gaps. To avoid this mistake, it is important for a CISO to thoroughly evaluate the capabilities of a SIEM solution and ensure that it is capable of collecting and analyzing data from all of the relevant systems and devices in the organization. This may include testing the solution's performance and scalability, and its ability to integrate with existing systems and processes.
2. Failing to Consider Long-term Cost of Ownership
While the initial cost of a SIEM solution may seem reasonable, it is important to consider the long-term costs of ownership, including the cost of licenses, maintenance, and upgrades.If a cyber information security officer (CISO) fails to consider these costs, they may end up choosing a solution that is more expensive to maintain over the long term than other options. To avoid this mistake, it is important for a CISO to carefully consider the long-term cost of ownership when evaluating SIEM solutions and selecting a solution that is cost-effective over the long term. This may involve comparing the costs of different options and weighing the costs against the benefits provided by each solution.
3. Underestimating the Importance of User Training
User Training is an aspect often neglected by most organizations. However, what they fail to understand is that user training is critical for the process of SIEM implementation. Security analysts handling the SIEM solution need to be aware of how the solution runs and how to make the most out of the solution. Moreover, at this implementation stage they need to be well-versed with the product, in order to gauge whether or not the SIEM implemented is functioning as desired. Even for certain functionalities and feature upgrades that require customization, the user needs to be well versed with the product. For this proper training is essential and for which it is important to choose a vendor offering a SIEM solution with comprehensive training and support for users, including offering ongoing education and updates on the SIEM solution.
4. Neglect Establishing Clear Goals & Metrics
It is important to establish clear goals and metrics for successfully implementing the SIEM solution and to also regularly review its performance against those metrics. This will ensure that the solution meets the needs of the organization and provides value.
For example, If an organization generates a large volume of log data from its systems and network devices, it will need a SIEM solution that is capable of efficiently collecting, storing, and analyzing that data. If a CISO chooses a SIEM solution that is not capable of handling the volume of data generated by the organization, it may struggle to keep up with the demands placed on it, leading to reduced performance and potential security gaps.
So, to avoid this mistake, a CISO should consider the volume of data that the organization generates and ensure that the chosen SIEM solution is capable of efficiently processing that data. This can be achieved by establishing clear goals and metrics for the solution and ensure not just the success of SIEM implementation but also ensure it functions effectively in terms of keeping up with the scale and volume.
5. Poor Configuration of SIEM Solution
Proper configuration is essential for ensuring that a SIEM solution is able to effectively collect and analyze data. It Is important to take the time to properly configure the solution and further periodically review and update the configuration as needed. Often organizations neglect this crucial process of customizing and fine-tuning the solution and face challenges in terms of getting the desired outcome. So, it is recommended that organizations appropriately configure the solution to ensure successful implementation of SIEM.
6. Lack of Management & Maintenance of SIEM
Like any other system, a SIEM solution requires ongoing maintenance and management to ensure that it continues to function properly. This includes tasks such as patching, updating, and testing the solution. In terms of achieving the long term implementation goals,Iit is important to keep the SIEM solution up to date with the latest patches and updates. This is to fix any known vulnerabilities and ensure that it continues to function properly. If a CISO fails to properly manage and maintain the SIEM solution, it may become vulnerable to attacks or result in malfunctioning, leading to reduced performance and potential security gaps.
7. Neglecting Regular Review and Analyze Log Data
A SIEM solution is only as useful as the data it collects and analyzes. So, to ensure it functions appropriately, providing the desired outcome, It is important to regularly review and analyze configurations, log data rules and more. This is to identify potential security threats and take appropriate action. Organizations often neglect reviewing and analyzing these essential aspects, resulting in frequent failures and disruption of operations.
8. Poor Integration Capabilities of SIEM
Evaluating the integration capabilities of a SIEM is an essential part of the implementation process. Only a successful integration of the SIEM solution with other security tools and systems can assure efficient and effective functioning of SIEM. For these reasons, a SIEM solution should be able to integrate with other security systems, such as firewalls and intrusion detection systems, to attain a comprehensive view of an organization's security posture.
9. Failing to Properly Protect the SIEM Solution
As a critical component of an organization's security infrastructure, it Is important to properly protect the SIEM solution. This includes protecting the solution against physical and cyber threats, as well as ensuring that it is properly configured and managed. Ensuring the solution is secure, updated and well configured will significantly contribute to the successful SIEM implementation.
