The SOC is the information security department that continually tracks, analyzes, and enhances the security situation of an enterprise. The goal of the SOC team is, using technological solutions and powerful process management, to identify, evaluate, and respond to cybersecurity issues. Security centers typically have information security experts, engineers, and managers who track all the occurring processes. To order to rapidly resolve security issues, SOC personnel work in close coordination with response teams in the area of incidents.
Because of increased cybersecurity threats, constant alert fatigue, and industrial challenges that make SOCs inadequate. SOC analysts are constantly weary. Routine as well as complicated tasks are automated to increase the time of analyst and speed up the operation. With attackers that are faster every day, cyber-security industry leaders agree that “automation” is a must in today’s cyber-threatening environment.
Many organizations, by offering structured training programs for staff who perform internal security functions and other interested parties, tend to create their own SOCs using their own resources. And others combine internally and externally. It is essential to store current workers in order to start developing a strong safety operations team.
Both a lot of skills and experience are required in monitoring, incident management, threat hunting, intrusion detection, reverse engineering, anatomy of malware, etc.
Before a SOC is created, security jobs are often in cluttered and hand-to-hand jobs. Who is doing what job, how problems are solved and documented do not go through a regular process.
With the SOC, workflows for incident management should be built from the beginning of the process to ensure that each phase takes place in a broader approach. Workflows lead to clarifying each team member’s position and responsibilities so that no stone tumbles.
Many organizations want technology tools that will support the visibility strategy and response to events in their networks and fit their budget.
To ensure maximum security coverage of your information systems, a comprehensive combination of tools is needed. Every effective SOC includes the main components SIEM (Security information and event management) system, an incident tracking and management system, intrusion detection and intrusion prevention (IDS/IPS/IDPS) systems, a threat intelligence (CTI) platform, packet capture and analysis tools and automation tools. A SOC team needs to be able to perform following actions with its technology.
- Network monitoring
- Endpoint management
- Asset discovery
- Threat intelligence
- Behavioral monitoring
- Data loss prevention
- Ticketing systems
- Policy compliance
- Incident response
All set open source solutions for SOC
Secure information and event management (SIEM) is a security management approach that combines the SIM (security information management) functions and the SEM (security event management) functions into a single security framework. SIEM tools analyze security warnings created by applications and networks in real-time.
Apache Metron: The Cisco Open SOC framework developed Apache Metron. Like SIEMonster, several open source solutions are also connected in a centralized network. Apache Metron can use standard JSON language to parse and normalize security events for easy analysis. In addition, safety warnings, data enrichment and labeling may be issued.

OSSEC: Technically, OSSEC is an open-source intrusion detection system rather than a SIEM solution. However, it still offers a host agent for log collection and a central application for processing those logs. Overall, this tool monitors log files and file integrity for potential cyber-attacks. It can perform log analysis from multiple networks services and provide your IT team with numerous alerting options.
Wazuh: Indeed Wazuh evolved from another SIEM solution, namely OSSEC, open source. Nevertheless, Wazuh is a special option for itself now. This facilitates the agent-based storage of data and the retrieval of syslogs. Wazuh can also track devices easily on-site. It has a dedicated web interface and detailed guidelines for quick control of IT admin.
Prelude OSS: Prelude OSS offers the Prelude SIEM solution with an open source version. It helps you to work with a large variety of log formats and other resources. It can also normalize event data into a common language, which can support other cybersecurity tools and solutions. Prelude OSS also profits from continuous growth, while retaining the current intelligence threat.
Snort: Snort also offers log monitoring as another open source intrusion detection system; it also carries out in real time network traffic analysis to identify possible dangers. Snort can view traffic or packet dump streams in a log file as well. In addition, output plugins can be used to decide how and where the dataset is saved.

ELK Stack: There are free SIEM products in the ELK Stack solution. For instance, ELK can compile logs from almost all data sources using embedded Logstash components. Therefore, this log data can be combined across a wide range of plugins, although manual security rules are necessary. ELK Stack can also display data with a specific portion.
SIEMonster: SIEMonster provides both a free SIEM and a paid solution. As is the case for many of the solutions used, the SIEMonster framework offers a centralized tool management interface for data analysis, threatening intelligence and various open source software. Your organization will host it on a cloud, unlike some other open source SIEM solutions.
B. Intrusion detection and intrusion prevention (IDS/IPS/IDPS) tools
An IDS is an automated system that detects unauthorized access to an information network device. Unauthorized access provides confidentiality, completeness or information.
An IPS a security tool capable of detecting inappropriate actions of network and/or program operations. A system of intrusion prevention may respond in real time to this by blocking or preventing such activities.
Snort: Snort is the best known open source IDPS solution for Windows and Unix, which provides intruders review, packet monitoring and full-fledged intrusion prevention capabilities in real-time.
Suricata: Suricata is an IDPS and network security control engine with a high performance network. Since it is multi-threaded, the processing load on a sensor is balanced in one instance.

E. Threat intelligence tools
Security analyzers scrutinize vast volumes of data to identify patterns and trends that provide actionable information about possible threats when analyzing cyber threats. The resultant knowledge of existing and future forms of threats is cyber threatening intelligence. By using intelligence on cyber threats, businesses gain a more detailed understanding of suspected bad actors in order to be able to proactively detect, plan and hopefully avoid cyber attacks and attempts to hack them.
Tools can use cyber threat intelligence to track and react to problems by quickly contrasting observed behavior with identified threats and flagged risks not captured by manual surveillance. Using a threat-intelligence tool will enhance your network safety and is important to keep your safety operations secure and vigilant.
