A reliable SIEM solution provider can deliver a range of functions that help your business detect and respond to threats. These include user behavior analytics (UBA), which illuminates deviations from normal data to highlight potential hazards and threat intelligence. It is crucial to have a dedicated IT team that can monitor your network and proactively address threats. However, hiring employees can be costly. Managed SIEM services are an affordable alternative.
Whether you have an on-premise SIEM deployment or choose a cloud-based model, your solution must be reliable enough to provide visibility into network activity that could introduce risk. This visibility allows you to identify and remediate security incidents quickly. A reliable SIEM tool will centralize alerts from all your various security technologies, such as firewalls, intrusion detection/prevention systems (IDS/IPS) and antivirus technologies, which typically generate a hefty volume of notifications. Then, a SIEM tool can apply threat intelligence to eliminate false positives and highlight suspicious activities to prioritize the most dangerous threats for your team to investigate.
Lastly, the right solution will provide visibility into your entire network environment with a real-time bird’s eye view that includes both on-premise and cloud data sets. You should also be able to drill down into data sets and get detailed information about the behavior of specific users, devices or applications. Using this capability, you can investigate attacks that may have occurred in the past and prevent future ones from happening. A reliable SIEM tool will also provide advanced capabilities such as unified endpoint detection and response (UEDR), network behavioral analytics, visual timelines for incident investigation, deception technology and centralized log management.
As your business grows, so will the amount of data you generate. Reliable SIEM solution providers should handle this growth and provide visibility. Enterprise tech buying teams should define requirements for their new SIEM solution that ensures it works practically and technically to deliver on their use cases and business needs. This list of requirements should be used to compare products and select the best one for your organization. Reviewing your organization’s security policy and how the data collected will be stored is also important. Using an MSSP (Managed Security Service Provider) to manage your SIEM solution can efficiently get the most value out of your investment. It allows you to spend more time on revenue-generating activities and less worrying about security threats and system uptime. A popular option is LogRhythm. Its robust platform can detect and mitigate threats from inside your network, as well as external ones. It also features protocol intelligence to give you context for security events, user and asset intelligence, and web and DNS intelligence. It is easy to deploy and integrate with other systems. However, it can be slow in generating insights and has storage limits. Additionally, it lacks UEBA capabilities.
There is a lot to consider when choosing a SIEM solution. Some of the biggest factors include cost and flexibility. A SIEM platform offered as a SaaS (Software as a Service) model can be more easily scalable and integrated with other threat intelligence systems. Most solutions also offer machine learning capabilities to help identify abnormal behavior. However, it’s important to be mindful that not all of these features are necessarily included with all SIEM products on the market. When assessing costs, be sure to evaluate both subscription and usage charges. The goal is to find a solution for your business to achieve its security goals and protect your data from threats while minimizing costs over time.
Whether selecting a managed SIEM service provider or going with an on-prem solution, review all your options and request product demonstrations. Security experts can assist you with this process and ensure you select the best tool for your unique needs. Its data analytics provide insight into cyber threats and attacks, and users can recreate full sessions to get a clear picture of how hackers work their way through your network. It also provides threat intelligence from multiple sources, including a global threat feed.
Whether deployed as an appliance or an application, SIEM solutions provide real-time monitoring of organizational systems to detect and mitigate security threats. They collect data from multiple sources within an enterprise—servers, network devices, domain controllers, firewall logs and antivirus/antimalware events—and use that data to search for patterns that indicate a possible security threat. They also can correlate this information from multiple locations, allowing organizations to view all of their data in one place regardless of where digital assets are being accessed. In addition to detecting and preventing cyber-attacks, SIEMs offer other valuable capabilities, such as the detection of lateral movement through IP addresses, credentials and machine behavior. They can also identify critical assets such as servers, medical equipment and machinery by analyzing their behavior for anomalies that may indicate a potential attack. They can even automate incident response by executing pre-planned responses when they detect a particular type of threat. Before selecting a SIEM solution, it is important to understand the organization’s specific needs and objectives. This includes assessing the volume and variety of data, IT resources, budget constraints, and nature of the business’s cyber threats. In many cases, it may be more cost-effective to partner with an MSSP (Managed Security Service Provider) to handle a SIEM solution’s deployment and ongoing management rather than investing in IT staff to manage these functions.
