What is SIEM Security?
Security Information & Event Management, commonly known as SIEM, is an approach to security management that seeks to provide a holistic view of an organisation’s information security systems, bringing them from multiple locations to one place.
SIEM centralises the storage and interpretation of security logs and allows for near real-time analysis, giving organisations the knowledge to take defensive action quickly.
Is SIEM Right for My Business?
The simple answer is yes. SIEM is needed by every business. Whether you are big or small, turnover 1 million or 1 billion, or somewhere in between, it is important to understand what is happening within your environment and ensure it is secure. SIEM allows you to do this, proactively monitoring the threats, detecting them, and dealing with them before they become a danger to your organisation. Implementing SIEM allows you to have greater knowledge of your network to proactively protect against ever-changing threats.
SIEM is state of the art security technology. Due to the amount of data being collected each and every day, SIEM requires two people to effectively monitor and manage it. This is necessary in order to make the most of the tool to filter out the noise and focus on the real activities that could have an impact on your business.
Due to their complexity and rigid requirements, SIEM projects often do not live up to users’ expectations, and failed or abandoned deployments are not uncommon within business. It is common to speak to clients who are purchasing their second or third SIEM technology after finding out their current technology doesn’t meet their business requirements.
Another reason why projects fail is due to underestimating the resources and skills required to implement and operate a SIEM system. Even a successful SIEM deployment is an expensive and resource-intensive proposition.
How to Implement SIEM Technology Successfully
- To achieve the best SIEM solution for your business it is best to use an “output-driven” approach to deploy the SIEM technology in order to determine scope and requirements.
- Work with system owners and operators to refine logging and audit capabilities.
- Implement a suitable deployment architecture to address the specified use cases and enable future expansion and growth for your business.
- Evaluate requirements — including for ongoing operations — and follow a formalised planning process before selecting a SIEM solution.
- Define the scope of the SIEM deployment and associated objectives early in the project.
- Plan for an initial 6 to 12-month road map encompassing the deployment of the SIEM solution and the phased implementation process.
- Simulate use cases to verify their soundness and effectiveness, as well as to test the incident response readiness of security personnel
What Kind of Data Can You Expect to See with SIEM?
SIEM will show you what’s going on in your business in real-time. Updating you on who’s logged on where, when, what they are using, and if any external threats are trying to get into your network. Any suspicious activity across the network will be highlighted to enable you to investigate.
