Take the time to consider the preparations necessary for successful expansion into the technology. The benefits of a sound, real-time security system are well worth the investment.
What is SIEM?
SIEM or Security information and event management is a set of tools that combines SEM (security event management) and SIM (security information management) Both of these systems are essential and are very closely related to each other.
SIM refers to the way that a company collects data. In most cases, data is combined into a specific format, such as the log file. That format is then placed in a centralized location. Once you have a format and location for your data, it can be analyzed quickly.
SIM does not refer to a complete enterprise security solution, though it is often mistaken for one. SIM relates only to the data collection techniques used to discover problems within a system.
SEM provides real-time system monitoring and notifies network administrators about potential issues. It can also establish correlations between security events.
What are SIEM Software Tools?
SIEM products run directly on the systems they monitor. The software sends log information to a central portal. This is typically a cloud server as they have more robust security monitoring than in-house hardware. They also provide a degree of separation for added protection.
A console provides clients visual aids filtered through local parameters. Cybersecurity incidents can be identified, recreated, and audited through accounting logs.
How Security Information Event Management Works
SIEM works by identifying the correlation between separate log entries. More advanced platforms also include entity and user behavior analysis (UEBA). Other systems may also include SOAR. SOAR stands for “Security Orchestration and Automated Response.” UEBA and SOAR are very helpful in specific instances.
Security Information and Event Management also works by monitoring and logging data. Most security operations experts consider SIEM tools to be more than a simple monitoring and logging solution.
A SIEM security system includes:
Actively develops lists of global threats based on intelligence.
Collecting logs from vetted sources of intelligence.
A SIEM solution consolidates and analyzes log file, including supplemental analytics data to enrich the logs.
Finds security correlations in your logs and investigates them.
If a SIEM rule is triggered, the system automatically notifies personnel.
Best Practices for Using a SIEM Solution
Identify Critical Assets To Secure
The first thing organizations must do is identify critical assets thru security risk management. Identification leads to prioritization. No company has the resources to protect everything equally. Prioritizing assets allows an organization to maximize its security within a budget.
Prioritizing assets also help in selecting a SIEM solution
Understanding a companies needs also helps to scale the SIEM platform used. SIEM technology can help with low-level compliance efforts without much customization.
Enterprise visibility is another goal altogether. This requires a much higher level of deployment. This goal does not require as much customization. Does your company know its goals? Take the time to form a detailed strategy before investing.
Train Staff to Understand SIEM Software
The second step is to ensure that in-house staff understands SIEM as a platform.
What system log files will the SIEM technology solution monitor? Does your company use a variety of logs? You may process data differently in various departments. You must normalize these logs before a SIEM security helps you. Different logs do not allow the system to execute to its maximum potential or deliver actionable reports. Why? The data is not consistent.
Create a Scaling Strategy
Some companies duplicate a logging strategy as they expand. The need for servers will eventually increase. As it does, the company reproduces the log rules. The log files will copy themselves as time goes on. This helps preserve records if a company is acquired or merges with another.
Creating a viable strategy becomes more difficult if servers are spread throughout different time zones and locations. Ideally, you would standardize the time zone your organization will use. Unsynchronized time stamps may result from neglecting this step. Finally, configure the triage of potential incidents on the system.
Make Sure the SIEM Solution Meets Your Needs
Each Security Information and Event Management comes with a log gathering requirement. For instance, Syslog logs connect through outsourced agents. Logs from Microsoft deal with locally installed agents. Logs are then collected centrally from a Remote Procedure Call or a Windows Management Instrumentation. Only then are they given to the devices collecting logs.
Executives are responsible for determining the security needs of each prioritized asset. This is essential to produce measurable and actionable results from a SIEM.
Log Only Critical Assets (at First)
Secondary features can roll out after configuring the full log environment. Managing this step by step helps to avoid errors. It also helps to hold back total commitment until the SIEM is tested.
Top SIEM Tools and Software Solutions to Consider
The capabilities of each SIEM product listed below vary. Make sure that you vet each system based on your individual needs.
Open source SIEM is quite popular. OSSEC is used most often as a host-based system for intrusion prevention and detection. This system is often abbreviated as an IDS. OSSEC works with Solaris, Mac OS, Linux, and Windows servers and Mac OS. It works well because of its structure. Two components comprise OSSEC: 1. the host agent and 2. the main applications.
OSSEC allows direct monitoring for rootkit detection, file integrity, and log files. It can also connect to mail, FTP, web, firewall, and DNS based IDS platforms. You also can synchronize log analysis from primary commercial network services.
Snort is a network-based IDS. It lives farther away from the host, allowing it to scan and monitor more traffic. As one of the top SIEM tools, Snort analyzes your network flow in real-time. Its display is quite robust: you can dump packets, perform analysis, or display packets in real-time.
If your network link has a throughput of 100 Gbps or higher, Snort may be the product for your company. The configuration has a high relative learning curve, but the system is worth the wait. Make sure that your staff has a sturdy grip on how to use Snort. It has robust analytical and filtering capabilities alongside its high-performance output plugins. You can use this SIEM tool in many ways.
ELK may be the most popular solution in the market. The ELK stack is the combination of products from SIEM vendors Elasticsearch, Logstash, and Kibana.
Elasticsearch provides the engine to store data. It is considered a top solution in the marketplace.
Logstash can receive your log data from anywhere. It can also enhance, process, and filter your log data if needed.
Finally, Kibana gives you your visuals. There is no argument in the world of IT about Kibana’s capabilities. It is considered the top open-source analytics visualization system produced in the industry so far.
This stack forms the base of many commercial Security Information and Event Management platforms. Each program specializes, making the entire stack more stable. This is an excellent choice for high performance and a relatively simple learning curve.
Are you making use of various open-source tools? Prelude is the platform that combines them all. It fills in certain holes that Snort and OSSEC do not prioritize.
Prelude gives you the ability to store logs from multiple sources in one place. It does this using IDMEF technology (Intrusion Detection Message Exchange Format).
