SIEM stands for security information and event management. SIEM is a software product that has created a solution to cybersecurity issues and data breaches for businesses. The cost of a data breach has climbed to $4.24 million on average in the United States alone. SIEM software aggregates and analyzes data across your network to check for anomalies and vulnerabilities that could potentially lead to a data breach. SIEM software will send alerts in real-time and define the threat level based on performance rules. SIEM combines security information management (SIM) with security event management (SEM) to create a comprehensive hybrid product that is used to protect against incoming security attacks with sophisticated AI technology. Implement SIEM Security to your Cloud Providers Start Now Request Demo SIEM Statistics To get a better understanding of why SIEM is so important, here are some valuable SIEM statistics to take into consideration: 60% of small businesses will have to close their doors due to the financial burden of a data breach. It can take as little as six months for a data breach to destroy a business entirely. Businesses lose $4.7 million to cybersecurity issues annually. 34% of data breaches come from insider threats. 69% of data breaches come from an external source. IT security professionals spend approximately 25% of their time dealing with false positives when their energy could be used elsewhere. 40% of IT security professionals say they cannot detect insider threats while they are moving data in and out. These are only a few reasons why businesses should use SIEM technology. Whether your business is a large corporation or an SMB, SIEM will be beneficial in keeping your information safe. SIEM itself does not protect your data, but it runs an analysis of all the data in your system to detect what kind of improvements can be made. It will also help your team stay on top of potential security threats and save you a lot of time and money in the process. How Does SIEM Work? SIEM security will help your business protect itself against all types of network issues such as patching software flaws or updating all existing applications. SIEM will gather data from all of your other protection programs such as antivirus and firewall systems to help improve cyber protection. SIEM works by leveraging security logs and system logs that IT professionals can analyze. The security information and event management architecture and operational processes used will aggregate data to discover potential threats. Adopting the SIEM framework gives your business a comprehensive data storage system to access and use to make improvements and an edge in the ongoing battle against cyber crime. Implementing a proper SIEM solution will provide you with extra security to make the framework you already have better. Data Storage As businesses continue to grow in the digital space, more information is being stored in the cloud, especially in the new interconnected remote workforce. This new WFH model leaves the information unprotected and open to phishing attacks and other threats unless businesses implement a SIEM strategy. Data leaks have been on the rise, and one of the biggest reasons is because data storage is not well protected.One of the most important things the SIEM framework can help you with is improving your data storage. When new data storage locations are created, your IT security team must be informed immediately. Your team needs to know what to prioritize to keep data breaches from happening. SIEM security logs can help with this. SIEM Policies One of the great advantages about SIEM is that you can implement your own policies that pertain to your business needs. When implementing SIEM into your enterprise, your IT team will need to create SIEM policies that will protect your data and define your security framework. SIEM policies include default rules, alerts, reports, and dashboards that can be tailored to fit the security needs of your business. They will have to adhere to SIEM compliance, and your SIEM Engineer will be able to assist in the creation. Depending on the type of business you have, you may be required to adhere to other compliance policies such as HIPAA if the business involves recording patient medical data and protected health information (PHI). Before implementing SIEM into your business, you should get a consultation to see which SIEM service is right for your business needs. Data Collection in SIEM SIEM collects and aggregates data throughout a company’s entire digital network. Data collection in SIEM involves gathering event and log data through all of the company’s digital platforms. These can include in-house networks, applications, antivirus and firewall protection software, and everything in between. The essential function of SIEM is to compile all of the data throughout a company’s infrastructure and put it into a comprehensive format for the IT security team to analyze. SIEM collects data such as login attempts, successful or failed. It also collects malware activity and all other unusual activity that could be a potential security breach. The Evolution of SIEM Software SIEM technology has been in existence since the mid-2000s. How did SIEM evolve? Well, SIEM is a compilation of previous security information management tools. The first version of SIEM evolved from the log management system, policies and processes used to deal with large volumes of data logs in an infrastructure. The term SIEM was coined in the 2005 Gartner report. The Gartner SIEM definition states that SIEM “caters to customers’ need to collect security event logs and telemetry in real-time for threat detection and compliance use cases, analyze telemetry in real-time and over-time to detect attacks and other activities of interest, investigate incidents to determine their potential severity and impact on a business.” This report for SIEM explained it as an information data collection system based on security information management tools (SIM) and security event management systems (SEM) combining them into one program. The security analytics Gartner magic quadrant is a report that comes out every 1-2 years that shows the state of the SIEM market and vendors. It’s a very useful tool for those using SIEM, or are looking to implement it in their enterprise. The Gartner report is more of a prediction. It predicts the trajectory of the market and what will happen with SIEM based on SIEM statistics and analytics. If you are using SIEM in your business, the Gartner report is essential to pay attention to so you are as up-to-date as possible on current SIEM trends. Implement SIEM Security to your Cloud Providers Start Now Request Demo Benefits of SIEM There are many benefits that come with implementing a SIEM strategy as part of your security arsenal. Using SIEM will save your IT department a lot of time when it comes to pinpointing cybersecurity threats. SIEM can also speed up the threat detection process, which can save security analysts over $1.2 million annually investigating false alerts. SIEM log management gives organizations a simple and concise way to analyze digital information within the company network to ensure there are no threats that can lead to security breaches. SIEM can be used for many different types of cybersecurity cases such as audits, compliance reporting, network issues, and security breaches. Without SIEM, this information is stored in separate areas in your network and cannot be accessed all at once, making it more difficult for your IT team to go through and check for issues. Not to mention other issues plaguing IT and analysts such as alert fatigue and tool sprawl. Another one of the SIEM benefits is that it will provide your IT security team with SIEM alerts in real-time to notify them of potential threats of a data breach. The products are customizable, and your team can develop a SIEM strategy that’s tailored to protect your data specifically. Threat Hunting and Detection SIEM alerts are sent with context and data for potential threats. Using SIEM gives you total visibility to display all of the potential issues within your data storage and infrastructure. SIEM will also detect past threats, identify new threats, and help you improve threat incident report time. Reduced Response Time Using a SIEM strategy will save your business a lot of time and money. With SIEM, your IT team will be able to detect a potential security breach before it even starts. This will reduce or eliminate the financial blow of the data breach. It will also save you from any damage to your business and IT infrastructure which can take up to 228 days on average according to a recent IBM report. Having the ability to detect a security breach or event before it even starts can keep them from happening at all. SIEM can also analyze past breaches and potential issues to help you keep them from occurring again. Security Staffing The IT team at your business should have specific employees designated for IT security. Those employees will be in charge of ensuring that your business adheres to SIEM and all other security compliances. If you have an IT team already, they should be familiar with SIEM. You will need to have a SIEM Engineer on staff that knows what they’re doing to keep things running smoothly. SIEM Compliance for IT Every business is responsible for adhering to SIEM compliance requirements. Typically, this refers to IT compliance which means detecting and reporting threats recorded in a data log. It’s important to research regulations specific to your particular business and adhere to them. You will need to log all relevant events and figure out what events are considered a threat to your business, as well as a complete detailed process of how to handle security events. Along with your own security standards, there are other compliances a business must take into account. One such compliance is the Payment Card Industry Data Security Standard or PCI DSS compliance. PCI DSS is a compilation of security standards for companies working with credit card information. To see if your business adheres to PCI DSS compliance, you can take the self-assessment questionnaire to see if you’re up to date with all security preventive measures. Not only is IT and PCI DSS compliance important for SIEM compliance, but there are also other institutions that require compliance. For example, SIEM can assist with Health Insurance and Portability Accountability Act (HIPAA) compliance. HIPAA compliance is essential for all medical businesses to protect confidential patient health information (PHI). A breach of HIPAA compliance is dangerous for your business and your patients. It could lead to the leaking of personal information, payment information, and medical records. SIEM will help ensure that HIPAA compliance requirements are met. The average cost of a healthcare data breach is $9.42 million per incident, the most out of all industries for data breaches. Along with HIPAA, all electronic medical data must comply with HITRUST. HITRUST is a data framework that focuses on medical businesses and hospitals. HIPAA compliance can be hard to understand, and HITRUST is a third party that helps to make it easier for businesses to comply. The Internal Organization for Standardization (ISO) is a global institution that manages standards for different industries. Your business will need to follow ISO 27001 standards. It is a framework built for information security management. ISO includes policies for how data is controlled and used in a business. SOC 2 Type 2 is a report that shows how a company is protecting their customer’s data and how well they are doing so. This report is typically used by businesses that store information in virtual data clouds. It assists businesses using third party technology to look out for risks. SIEM Management Best Practices Develop a SIEM Strategy – Start by defining key objectives and SIEM deployment during the initial or planning phase. Identify any key vulnerabilities that need to be immediately addressed. Once you have these SIEM objectives mapped out, you can then start small and test out a pilot run before implementing a more comprehensive SIEM deployment plan. Consider Your Compliance Requirements – Compliance is a critical component of building a successful and effective SIEM game plan. Consider which compliance regulations your organization might need, such as HIPAA, HITRUST, GDPR, and ISO 27001 among others. Being fully compliant with the relevant regulations can help save your organization hundreds of thousands of dollars if not more in potential penalties down the road. Collect Log Data – Data will tell you everything you need to know about your current security posture. Collecting log data can help uncover security flaws that could be opening the door to potential attacks. Analyzing user privilege access, application errors or small details in your terms and conditions can help detect anomalies and reduce the attack surface. Have a Threat Response Plan – Choose a SIEM solution that meets your unique requirements and assign the relevant roles to your IT department. Security analysts and MSP’s must be briefed before you implement a final SIEM framework. Guidelines should be established with an effective incident response plan to remove any potential threats and provide a playbook for your security team to follow. What is The Role of a SIEM Engineer? The SIEM Engineer will play a major role in an IT security team. They will be the leader that manages SIEM reports and puts together a well-defined blueprint strategy from the beginning. The engineer is in charge of implementing SIEM and ensuring all parts are functioning properly. They will review all reports and identify any breaches or areas that need to be addressed in the bigger picture. There is probably someone on your current IT team that will be able to assume the role of SIEM Engineer. If not, you will need to hire one. SIEM will not function properly without the assistance of experienced professionals who understand the framework. SIEM vs Log Management: Key Differences SIEM and log management solutions may seem similar, but the only thing they have in common is the fact that they both revolve around data logs. Logs are essentially all of the data records a company keeps. They can tell you a lot about a business. Networks are always collecting data and putting it into logs, and your IT team can use log management tools to go through it. The problem is most businesses have so much data that it can take a long time to go through the logs. In fact, the average company manages 162.9TB of data with enterprises having over 347.56TB to analyze. That’s a lot of data. With centralized log management, the data is still not automated. This means your team will still have to sift through it for information. It takes a lot of time and can be costly. SIEM also utilizes data logs, but in a more efficient manner. It is also important to note that log management tools are solely to collect data, and SIEM uses the logs to find ways to improve cybersecurity. SIEM is much simpler to use and more cost-effective than relying on just logs. What is The Difference Between SIEM and SOC? SIEM and Security Operations Center (SOC) are both important forms of technology in cybersecurity. SIEM utilizes data logs to find threats, while SOC is in charge of resolving the threats. The two go hand in hand and cannot function without the other. SIEM and the SOC work together to ensure that the alerts are not false positives, and if they aren’t the SOC will get to work resolving the issue. Security Intelligence and Analytics: Bringing All The Data Together So, what is all this log data showing the IT team through SIEM analysis? The main things SIEM is looking for are data security events. By using log data management, the SIEM engineer can work on network anomaly detection. Network anomaly detection can spot the tiniest of problems that can carry enormous financial consequences. Having all of your log data in one spot makes it easier for your IT security team to compare and contrast large amounts of data. SIEM Cloud Vendors Using SIEM Cloud Vendors gives IT teams a more convenient way to manage cybersecurity threats.
