  • Another way to decide is to look at what problem you’re trying to solve with the tool. Over the years, the following areas where SIEM and log management tools can deliver value have emerged: Security, detective, and investigative: sometimes also called threat management, this focuses on detecting and responding to attacks, malware infection, data theft and other security issues. It is very useful to see this as two separate factors: monitoring and detection of security issues vs investigation and forensic analysis of security incidents.Compliance, regulatory (global) and policy (local): this focuses on satisfying the requirement of various laws, mandates and frameworks. Most of the mandates have the intention of helping you improve security, so there is a lot of overlap between this and the previous item.Operational, system and network troubleshooting and administration: specific mostly to log management, this use case has to do with investigating system problems as well as monitoring the availability of systems and applications.
  • Security Information and Event Management covers relevant log collection, aggregation, normalization, retention; context data collection; alerting; analysis (correlation, prioritization); presentation (reporting, visualization); security-related workflow and relevant security content. Typical uses for SIEM tools center around network security, data security as well as regulatory compliance.  On the other hand, Log Management includes comprehensive log collection, original log retention; analysis; presentation (search, reporting, and visualization); related workflow and relevant content such as reports and search queries. Log management usage is broad and covers all possible applications for log data across IT and even beyond information technology – but certainly includes security and compliance use. To summarize this, SIEM focuses on security while log management focuses on a broad use for log data. Most specifically, SIEM tools include correlation and other real time analysis functionality, useful for real-time monitoring. Log tools often focus on advanced search across all log data. Today, many tools combine select capabilities of SIEM and log management in a single product or product suite.
  • What is correlation? Different definitions given by different people.Dictionary: “establishing relationships”Why correlate events?Cross-device data analysisWhat else one might want to correlate?Events and …
  • First, compile a list of regulations that you have to comply with, focus in particular attention to areas where a SIEM or log management tool can be useful. In many cases, the list will contain only one regulation – but the one you absolutely must handle. Next, if possible, review other possible goals that SIEM can help you achieve. Deciding whether SIEM satisfies a critical business need – such as by as an enabling technology for your SOC– is an essential step.  Third, at this point you must decide whether you are prepared to work to make SIEM solve your problem – whether compliance or other. Despite help from the vendor and possibly consultants, there are areas where you have to work to make SIEM work. Now, acquire and implement the SIEM solution. This is where you work jointly with the vendor in order to build your initial implementation for regulatory compliance, such as PCI DSS.Now, start actually using SIEM for both “letter and spirit “ of the regulation. This is the most important step in the approach – one of the biggest mistakes organizations make in this area is thinking that simply owning a SIEM tool makes them compliant. In reality, building daily operational procedures and processes to go with your SIEM is the only way to do that. Sadly, few people remember that PCI DSS prescribes a large set of periodic tasks, from annual to daily (log review being the most well-known example of a daily practice) and not just “having logs.” Finally, expand the use case to beyond compliance. Only at this step you can plan for expanding deployment and solving other problems. The tips for that are provided in the next section. One way to quickly grow your security capability is on the incident response side. This is due to the fact that the easiest and most common security use for log management and SIEM tools - beyond compliance - is related to incident response and forensics.
  • SIEM for Compliance Mistakes The most burning logging, SIEM and compliance mistake is simply this: thinking that to be compliant you have to have logs collected in a log management tool – and do nothing else. This mistake is as egregious as they come – simply reading the text of most regulations will uncover such items as log review, log protection, logging specific details for various events, handling exceptions and many other items. PCI DSS prescribes log review and log protection, HIPAA calls so monitoring, NERC asks for incident process ease; not a single regulations is only about storing logs. A second common mistake is focusing on the letter of regulations – and not their intended spirit. The best way to summarize it is: if you focus on security, you have a shot at being compliant and secure; if you only focus on compliance, you will likely not be secure and not compliant. Just us could the victims of recent breaches who were justifiably found to not be compliant. Finally, silo’d approach to regulations is unfortunately the norm today. Still, it does not make it right – it is still a mistake. Given a large overlap across regulations in what the mandate in regards to look logging, security monitoring, change detection, incident response and other security practices, it makes sense to implement this super set of requirements and not try to “chew” on regulations one by one, wasting resources and causing delays.
  • Every time you think “Compliance OR security,” god kills a kitten!
  • Conclusions  While some organizations, continue to try to degrade sensible security choir events to some minimum baseline, this and not a recipe to create customer trust and protect the data. Some of the recent challenges with SIEM and log frequently stem from the fact that powerful SIEM technology is purchased to address a compliance mandate – and to do so in narrow and short-sighted fashion. Following our roadmap to effective use of SIEM for compliance in beyond will allow you to avoid the mistakes and gain all the benefits you paid for when procuring a SIEM or log management tool. Next, you can then expand the use of a SIEM beyond compliance to security and operational use cases happens, focusing on improved incident response practices and then going to near-real-time automated security monitoring. This is the only way to gain visibility and thus control over your ever growing IT environments. This is also the only way to prepare for the onslaught of virtualization and cloud computing, which will muddy the waters of what information and IT assets needs to be protected. The final word on succeeding with SIEM is hereby this: start using the regulatory guidance, take it to heart, operationalize it, then expand to solving “bigger and better“ problems.
