With the rapid development of network technology, the world has entered the era of information and digitalization. In the process of computer network technology, some destructive network threats may be encountered, which may lead to the disclosure of their privacy.
However, the establishment of SOC can protect network data security to a large extent, prevent network threat attacks, and restore lost data, but what is SOC? Why are they so important? At iSEMC, we utilize technology and centralize equipment to optimize operations. To help you do this, we have produced a complete SOC guide; we will discuss SOC definitions, responsibilities, and basic functions.
What is a security operation center?
The security operation center handles real-time network security.
Incidents and monitors detect, analyze, respond to, and report security incidents.
Discovering potential network attacks and remediating system vulnerabilities before attackers exploit them. The SOC should be able to run 7*24 hours a day to check network security incidents in real time and solve problems. Also, SOC can improve customer confidence.
Also, strengthen the legality of industry, country, and global privacy.
Responsibilities of a Security Operations Center (SOC)
The activities of the SOC are divided into three main areas.
1st part-Prepare, plan and prevent
A Security Operations Center (SOC) will conduct routine maintenance and readiness:
To maximize the effectiveness of existing security tools and measures.
These tasks include but are not limited to application software patches and upgrades.
And updating firewalls, allowlists, blocklists, and security policies and procedures.
Additionally, the SOC creates regular system backups or assists.
With backup strategies and plans to ensure business continuity. During a data breach, ransomware attack, or other cybersecurity incident. Through these measures, the SOC works to improve security.
Reduce the risk of potential threats and safeguard the organization's secure environment.
Incident response strategy planning:
The Security Operations Center (SOC) handles developing an organizational incident.
Response plan that defines the steps to be taken should a threat or incident occur.
The roles and responsibilities involved establish the criteria by which incident response success or failure will measured.
Periodic evaluation. The SOC team will conduct a comprehensive vulnerability assessment to determine each asset's potential threat vulnerabilities.
Additionally, they will conduct penetration testing, simulating and implementing a specific attack in another environment. Based on these test results, teams patch or optimize applications, security policies, best practices, and incident response plans.
Track dynamics in real-time. The SOC will continue monitoring security solutions, technological advancements, and threat intelligence. This information may come from social media, industry sources, and the dark web. News and information related to cyber-attacks and attacker behavior will be collected.
2nd part-Monitor, detect and respond
Continuous security monitoring:
A Security Operations Center (SOC) monitors the entire extended IT infrastructure, including applications, servers, system software, computing devices, cloud workloads, and networks, on a 24x7, year-round basis, looking for signs of known vulnerabilities and any suspicious activity.
For the SOC security operation center, core monitoring, detection and response technologies have been incorporated into the scope of security information and event management.
The SIEM system will check and centralize data generated on software and hardware and analyze these data to identify potential. Recently, some SOCs have also begun to adopt extended detection and response technology, which provides more detailed monitoring data and can execute incidents and responses.
Incident response:
SOCs take various actions to mitigate damage in response to threats or incidents. These measures may include:
- Conduct a root cause investigation to determine the technical vulnerability that allowed the hacker to access the system and other factors (such as poor password hygiene or policy enforcement) contributing to the incident.
- Shut down or cut off the network connection of the infected terminal device.
- Isolate compromised network areas or reroute network traffic.
- Pause or terminate the infected application or process.
- Delete damaged or infected files.
- Perform antivirus or antimalware operations.
- Disable passwords for internal and external users.
3rd part-Recovery, Optimization and Compliance
Restoration and repair:
Once the incident is contained, the Security Operations Center (SOC) will take action to neutralize the threat and subsequently restore the affected assets to their pre-incident state. This may include wiping, restoring, and reconnecting disks, end-user devices, and other endpoints, restoring network traffic, and restarting applications and processes. If a data breach or ransomware attack is involved, the recovery process may also involve switching to a backup system and resetting passwords and authentication credentials.
Post-analysis and optimization:
Security operations centers (SOCs) will leverage new intelligence from incidents to prevent similar incidents from happening again. This intelligence will help to better identify vulnerabilities, update processes and policies, select new cybersecurity tools, or modify incident response plans. At a higher level, the SOC team might also set out to determine whether the incident signifies a new or changing cybersecurity trend, allowing the team to prepare.
Compliance management:
The responsibility of the Security Operations Center (SOC) is to ensure that all applications, systems, security tools, and processes follow the requirements of data privacy regulations, such as GDPR (General Data Protection Regulation), CCPA (California Consumer Privacy Act), PCI DSS (Payment Card Industry Data Security Standard), and HIPAA (Health Insurance Portability and Accountability Act). After the event, the SOC will ensure that the requirements notify users, regulatory agencies, law enforcement agencies and other relevant parties of regulations and that the necessary event data is properly preserved for evidence collection and auditing.
Technology Requirement
To improve team efficiency and visualization, SOC uses an LCD or LED video wall, a group of displays that appear as a single surface. And with video wall processors, matrix switchers and video wall controllers to ensure that the SOC teams can connect to remote networks and send all the information needed for efficient communication in real-time.
Features for security operation center room
Real-time video monitoring
The video wall display system can work for 7 X 24 hours to ensure the timeliness of scheduling and control. The camera can connect to the monitoring platform through the network. Also, the data can be stored through the disk array for uninterrupted supervision.
Visual display
All systems are more visual, with pictures, data, video, software interface, and other related ways, which are more intuitive and vivid.
Remote storage
The image transmission function enables instant transmission of image streams via the media server when many users request real-time viewing of the same camera. This design reduces video bandwidth usage in the same point monitoring system, preventing network congestion from internal service interruption.
Linkage alarm
After integrating an infrared detector at the front end and establishing a connection to the backend alarm host, which is also linked to sound and light alarms, any unauthorized intrusion triggers the activation of alarms. Based on preset configurations, a series of corresponding actions will initiated. Comprehensive alarm data will gathered from various triggers on the business client's end.
The alarm interface allows for managing the planning and on-site execution of each alarm response; diverse alarm data will undergo categorized analysis through an alarm information statistics process. Video equipment will synchronize through the linkage, enabling the real-time transmission of live video to the display terminal. This integrated approach ensures the seamless functioning of alarm responses while providing the capability to send live video for immediate viewing.
Preset management
The integrated security management platform can associate emergency plans applicable to police information situations.
This automated linkage mechanism helps to provide timely and effective decision support and a more convenient way for management to make wise judgments in emergencies.
Electronic map
Support a 3D multi-layer electronic map, allowing for seamless surveillance and mapping capabilities integration. Choose monitoring and alarm points on the map with controls. Enjoy the convenience of map scaling to adjust the view as needed. When an alarm is triggered, the corresponding alert can visualized at the relevant map location. By clicking on the alert icon, users can access scene images and even exercise PTZ (Pan-Tilt-Zoom) control for closer examination.
Investigate cases based on video.
With intelligent applications such as video concentration, summary, and retrieval, video viewing can be more efficient. Through image enhancement technology, blurred images can repaired so that the details and features of the image are clearer. Also, intelligent image processing technology, including image repair, supports actual security services.
Ultra-high-definition display
The system of SOC is compatible with DID screens, DLP splicing, and LED display screens.
