Security Information and Event Management encompasses a wide range of specialised fields, such as Log Management Systems, Security Information Management, Security Log/Event Management, and Security Event Correlation (SIEM). Combining these features into a single, comprehensive view is standard practise.
There is no such thing as a completely secure SIEM system, but having one in place is usually a sign of a solid cybersecurity strategy. Most times, there are no outwardly visible indicators of a cyber attack. The best way to find security flaws is via examining log files. Because of their exceptional log handling capabilities, SIEMs have become a central point of network visibility.
Most security strategies don't think broadly enough about potential threats in the cyber realm. An IDS can usually just monitor packets and IP addresses. This means that your service logs will only contain information relevant to user sessions and configuration. When these components are coordinated, SIEM can keep a constant eye on things and use analysis of event logs to paint a full picture of any security breach.
For What Reasons is SIEM Valuable?
The security information and event management system (SIEM) has developed into an integral aspect of modern enterprises' security architecture. All users and trackers leave some sort of digital trace in the network's log data, which is the primary reason. In order to learn from past assaults and occurrences, incident and event management systems are built to analyse these data. The purpose of a security information and event management system (SIEM) is not only to report the presence of an attack, but also to provide insight into the circumstances and causes of that assault.
As firms have upgraded to more advanced IT systems, the value of SIEM has increased. Antivirus and firewall programmes are not enough to protect today's networks. This protection does not guarantee that a system will not be compromised by a zero-day attack.
SIEM solves this problem by keeping an eye on network traffic for indicators of attacks and assessing them against previous examples. A SIEM system can distinguish between a legitimate user login and an attempted intrusion. This reduces the likelihood of data corruption or loss and strengthens the resilience of your system.
Several different cyber management standards exist, and SIEM can help firms conform to them. Log management is the standard by which all other methods of auditing network activity in IT must be measured. A SIEM system is the only way to satisfy this regulatory mandate while also providing visibility into logs to create actionable insights and improvements.
Competencies in SIEM
The following are some of the primary functions of a SIEM system:
- Normalization of Data Retrieval – Converting Unstructured Data into a Form That Can Be Used
- Warnings and Warnings: Informing the User of Potentially Dangerous Events
- Identifying the Existence of a Security Incident Procedure for Handling Past Incidents in
- Light of Current Threats.
A SIEM keeps track of data collected by an organization's own toolset and performs an analysis to identify potential vulnerabilities and attacks. The system employs a statistical model to make sense of the collected information. Two of a SIEM system's primary roles are to disperse collecting agents and to get information from various sources, including the network, servers, devices, and firewalls.
This information is transmitted to a command centre, where it can be analysed to identify and neutralise potential security risks. Modern SIEM systems typically incorporate automated responses, entity analysis capabilities, and security orchestration. In this approach, your entire suite of cybersecurity tools may be monitored for vulnerabilities and patched by the SIEM system.
A data analyst can review the information and provide feedback once it reaches the command line. Learning from its environment, the SIEM system can make better use of machine learning with the help of user feedback.
Once a security concern has been identified, the SIEM software system will work in tandem with the device's other security capabilities to promptly disable the offending activity. With its emphasis on collaboration, SIEM systems have found widespread adoption in business settings. Despite this, many SMBs are debating whether or not to invest in a SIEM system in light of the increasing sophistication of cyber threats they face.
The hefty cost of SIEM implementation has delayed this change until recent years. The system itself is expensive, and you'll need to dedicate staff time to monitoring and maintaining it. Therefore, there has been a decrease in the interest shown by smaller enterprises in adopting SIEM. Even so, things have started to change because of managed service providers that SMEs can outsource to.
The SIEM Applications' Inadequacies as a Comprehensive Data Security Ecosystem
It is common knowledge that SIEMs can't make heads or tails of unstructured data like emails, and because SIEM programmes provide next to no context data about their native events. Although network activity from a given IP address can be traced, the identity of the user or the content of files viewed at any given time cannot.
It's possible that the setting is essential here.
What seems to be a large transfer of data could actually be the theft of petabytes of sensitive and critical data. An immune system will develop in response to false security warnings if no context is provided.
Currently, SIEM software does not provide a method for categorising data. As a result, they are unable to distinguish between benign file activity and that which poses a risk to the privacy of their customers, the confidentiality of their intellectual property, or the security of their business.
SIEM applications are only as effective as the data they are presented with. False alarms and other small issues frequently leave IT scrambling for answers without any additional context. When it comes to data security, the right battles to fight depend heavily on the surrounding circumstances.
We have found that the most common SIEM-related customer complaint is the time and effort required to properly diagnose and investigate security alarms. Users receive a warning, but due to the plethora of low-level data and the sheer volume of alerts, they frequently lack the clarity and meaning to act on that alert promptly.
The Top ten Security Information and Event Management Tools
Security System Tracking using Datadog
Datadog is the best option for monitoring your systems. Security features of the system reside in a separate module. Real-time events are monitored, but they are stored as log file entries, making it a full SIEM system because it can process both log information and monitoring data. The service's local data is collected by an agent and then uploaded to the Datadog server. All notifications are processed and archived by the security alert system.
As soon as a security breach is detected, a notification will be shown in the administration panel. The admin panel is where you'll find all of the logs documenting system events. There is an index for each message that is preserved for a period of 15 months. They can be analysed directly in Datadog's console, or exported for use in another analytics tool.
By offloading processing, you can free up some of your own system's resources to use elsewhere. Also, it makes remote network monitoring much easier. The analysis service employs a predefined set of rules to identify typical attack techniques.
Datadog instantly adds new attack methods it discovers to its pool of detection criteria. The cloud makes it possible for security software to be automatically updated, relieving system administrators of that duty. Adding new detection and prevention rules is simple for the system administrator.
The SolarWinds® Security Event Manager
When it comes to low-end security information and event management (SIEM) software, SolarWinds Security Event Manager (SEM) is a top contender. The SEM is equipped with all the typical SIEM features, such as log management and reporting. With its comprehensive real-time incident response, SolarWinds is ideally suited for those who wish to actively monitor their infrastructure in preparation for future assaults utilising Windows event logs.
One of the best parts of the SEM is the intuitive and comprehensive dashboard. The sophisticated visualisation capabilities make it easy to see anything out of the ordinary. If you ever have a problem and need assistance, you can contact the company at any time of day or night.
Analyzer of Engine Events Manipulation
A security information and event management (SIEM) solution, Manage Engine Event Log Analyzer focuses on managing logs and deriving performance and security insights from them.
This programme can be used to collect data from both the Windows Event log and the Syslog. The application will then place the messages in the appropriate directories and files, relocating them to new files if necessary. The EventLog Analyzer then prevents any further changes to the files.
Yet ManageEngine is so much more than a simple log server. In the event of any unauthorised use of corporate resources, you will be alerted immediately. You can use this to check the health of your most important services and programmes, such your web servers, DHCP servers, databases, and print queues.
Compliance with data security regulations can be demonstrated with the help of EventLog Analyzer's auditing and reporting tools. The report generator supports the report formats required by the PCI DSS, HIPAA, FISMA, GLBA, SOX, and ISO 27001.
Enterprise-Level Security with Splunk
Splunk is one of the most well-known choices for SIEM management. It stands apart from other SIEMs due to the emphasis it places on analytics. The system is continually searching for vulnerabilities and flagging any strange behaviour thanks to real-time monitoring of network and machine data. Enterprise Security's Notables function offers a personalised news feed of notifications.
Thanks to the straightforward design of the interface, fixing any security holes will take little time at all. When examining an incident, the user can start with a high-level summary and then navigate into more particular details. The Asset Investigator can also successfully identify malicious activities and halt its progression.
If you're looking for an IDS/IPS system that runs on your host machine, look no further than OSSEC (HIDS). Not only is OSSEC a highly effective HIDS, but it is also free to use and distribute. OSSEC fits the definition of a SIEM tool because the services it offers are similar to those offered by SIM systems and HIDS techniques.
As a result, the application primarily looks at log files for indicators of suspected invasions. In addition to checking logs for suspicious activity, the programme checks file checksums to see if any data has been tampered with. Hackers frequently use complex intrusion software to alter log files after a successful breach to prevent detection.
Since OSSEC is freely available and can be used by anybody, its implementation across the network is a no-brainer. The software just examines the host's local log files. The software's developers are aware that there are differences in how logging is implemented between operating systems. Consequently, OSSEC will check the Windows Event logs for attempted registry access and the Syslog records for attempted root access on Linux, Unix, and Mac OS machines. Because of the software's enhanced functionalities, it may exchange data with other devices in a network and store all of the discovered logs in a single SIM log storage.
Trend Micro is a for-profit entity that provides OSSEC at no cost to users, although it retains ownership of the programme. Although it is not great, you can get this system's user interface as a separate programme. Kibana and Graylog are two popular front ends and analysis engines used by OSSEC users.
