SIEM (SECURITY INFORMATION & EVENT MANAGEMENT) TOOLS

?? Hello !! In this Article we will Learn about SIEM Tools, What these Tools Provide and What are the benefits of Using these Tools.

?? Let's Begin.

-----------------------------------------------------------------------------

? What is SIEM ?

?? Security information and event management?(SIEM) technology supports threat detection, compliance and security incident management through the collection and analysis (both near real time and historical) of security events, as well as a wide variety of other event and contextual data sources.

??It is a software solution that aggregates and analyzes activity from many different resources across your entire IT infrastructure.

?? SIEM collects security data from network devices, servers, domain controllers, and more. SIEM stores, normalizes, aggregates, and applies analytics to that data to discover trends, detect threats, and enable organizations to investigate any alerts.

-----------------------------------------------------------------------------

? History of SIEM ?

?? Gartner coined the term ‘SIEM’ (pronounced “sim”) in a 2005?report?called “Improve IT Security With Vulnerability Management.” The term brings together the concepts of security event management (SEM) with security information management (SIM) to achieve the best of both worlds.

?? SEM covers the monitoring and correlating of events in real time as well as alert the configuration and console views related to these activities. SIM takes this data to the next phase, which includes storage, analysis, and reporting of the findings.

-----------------------------------------------------------------------------

? How Does SIEM Works ?

?? SIEM works by combining two technologies:

• Security information management (SIM), which collects data from log files for analysis and reports on security threats and events, and
• security event management (SEM), which conducts real-time system monitoring, notifies network admins about important issues and establishes correlations between security events.

?? The security information and event management process can be broken down as follows:

1. Data collection?– All sources of network security information, e.g., servers, operating systems, firewalls, antivirus software and intrusion prevention systems are configured to feed event data into a SIEM tool. Most modern SIEM tools use agents to collect event logs from enterprise systems, which are then processed, filtered and sent them to the SIEM. Some SIEMs allow agentless data collection. For example, Splunk offers agentless data collection in Windows using WMI.
2. Policies?– A profile is created by the SIEM administrator, which defines the behavior of enterprise systems, both under normal conditions and during pre-defined security incidents. SIEMs provide default rules, alerts, reports, and dashboards that can be tuned and customized to fit specific security needs.
3. Data consolidation and correlation?– SIEM solutions consolidate, parse and analyze log files. Events are then categorized based on the raw data and apply correlation rules that combine individual data events into meaningful security issues.
4. Notifications?– If an event or set of events triggers a SIEM rule, the system notifies security personnel.

-----------------------------------------------------------------------------

? Why to Use SIEM ?

?? It’s no secret that security threats are increasing, and they can come from both internal and external sources. One rapidly rising concern is that of employees who accidentally misconfigure security settings in a way that leaves your data vulnerable to attack. To address these issues, IT organizations have put various systems in place to protect against intrusion and a host of different threats

?? With SIEM software, IT professionals have an effective method of automating processes and centralizing security management in a way that helps them simplify the difficult task of protecting sensitive data. SIEM tools gives these experts a leg up in understanding the difference between a low-risk threat and one that could be determinantal to the business.

-----------------------------------------------------------------------------

? Benefits?of SIEM ?

?? SIEM solutions have the ability to:

• Centralize your view of potential threats
• Centralized management and executive dashboards
• Monitoring unique data sources

-----------------------------------------------------------------------------

? Use Case of SIEM ?

?? With a SIEM solution in place, your administrators gain insights into potential security threats across critical networks through data normalization and threat prioritization, relaying actionable intelligence and enabling proactive vulnerability management. There are multiple use cases in which a SIEM can mitigate cyber risk. By monitoring an organization's data streams, a?SIEM can detect abnormal behavior and suspicious activity with:

• ?Logins and logouts
• ?User additions, deletions, and privilege changes
• ?User behavior
• ?Configuration alterations
• ?Services starting and stopping
• ?Roles added or changed

? Some of the SIEM Tools.

• SolarWinds Security Event Manager

?? SolarWinds Security Event Manager provides all the log management features you need:?security event-time correlation, compliance reporting, and advanced analytics features. It’s built for businesses that are specifically looking for robust log monitoring as well as better prioritization and response for incident management

-----------------------------------------------------------------------------

• Micro Focus ArcSight ESM

?? ArcSight has an open architecture which gives it a few standout capabilities. This tool?can ingest data from a wider range of sources than many SIEM products, and its structured data can be used?outside?of ArcSight, which may be useful for more expert IT teams. What’s more, Micro Focus just acquired Interset, a security analytics software company, to add to its behavioral analytics and machine learning portfolio. I wouldn’t count on those capabilities showing up in ArcSight just yet, but it could be worth keeping an eye on this end of the market.

-----------------------------------------------------------------------------

• SolarWinds Threat Monitor

?? SolarWinds Threat Monitor is a powerful security-focused SIEM solution that?analyzes security log info across a range of sources and cross-checks anomalies against a continuously updated global threat database. This tool gives you automated, intelligent responses to security events plus comprehensive alerts.

-----------------------------------------------------------------------------

• Splunk Enterprise Security

?? Splunk Enterprise Security is a popular option that has been around for over a decade. As the name implies, this is an?enterprise-level option, which also means the licensing costs aren’t particularly competitive — this tool may be too pricey for some. You can get this tool as?on-premises software or as a SaaS solution (ideal for AWS users). The dashboard has useful visualizations like graphs and charts. It supports as many plugins and third-party integrations as you’re likely to need. That said, the learning curve can be steep if you’re looking to take advantage of deeper analytics features

-----------------------------------------------------------------------------

• LogRhythm NextGen SIEM

?? This is a solid, fast option for?critical log management on Windows. The tool is fairly easy to deploy for trained IT staff, and the dashboard helps simplify workflow. If you have specific compliance standards and know your queries, it’s quick to configure the reports you need. This tool?has rapidly-evolving AI and automation features, which isn’t the case with every tool. All this being said, this platform doesn’t scale particularly well for larger businesses, and there’s limited support if you need to expand into cloud environments.

-----------------------------------------------------------------------------

• IBM QRadar

?? Businesses looking to integrate a wide range of logs across their critical systems will likely find QRadar reliable. Plus,?this IBM product has smart features that catch a diversity of ever-changing threats. It’s not necessarily the most intuitive product, as it has a complex architecture to match its capabilities. For instance, setting alerts in QRadar can be a bit cumbersome.?Of course, IBM products come with the higher price tag you would expect, but enterprises with extensive log management needs should consider this solid option

-----------------------------------------------------------------------------

• AlienVault Unified Security Management

?? This is a decent option for SMBs looking for an entry-level SIEM product, and it can be?implemented on both Mac and Windows. This product doesn’t offer the breadth of features of leading competitors, although it?recently added endpoint detection and new response capabilities. It’s worth pointing out that AlienVault was acquired by AT&T in 2018, but so far, it’s unclear whether this will have an impact on this product.

-----------------------------------------------------------------------------

• Sumo Logic

?? This is a newer,?cloud-based platform that is appropriate in terms of both cost and features for SMBs. Since the product is new, there isn’t much of a community base in place, but Sumo Logic claims its product fills gaps in IT security that other products have missed — especially when it comes to cloud deployments. Note that this tool seems to have more of a technical user in mind, so the design features aren’t as appealing.

-----------------------------------------------------------------------------

• RSA NetWitness Suite

?? Another solid option for log management and threat intelligence. With a maintenance and support agreement,?you get over two dozen intelligence feeds populated by RSA to add to whatever intel you enter into the system. All this allows for robust threat analysis. In fact, with this SIEM tool, you can recreate full sessions to see exactly what happened during an attack and get insight into hackers’ tactics with automated behavioral analytics. It’s on the upper end of the pricing spectrum, so it might be more appropriate for enterprises.

-----------------------------------------------------------------------------

• McAfee Enterprise Security Manager

?? This is a familiar option but be warned that other McAfee products have been discontinued abruptly in the past. On top of that, the product’s log sharing with tools from other vendors isn’t straightforward. However, if you’re already implementing other McAfee products like their famed antivirus software, it may make sense to choose a McAfee SIEM solution to streamline your operations. In any case, selecting this solution will get you?the basic dashboard management and reporting capabilities you need, so it might be worth checking out the price point to see if it makes sense for you.
