What is Security Operation Center and it’s Key Functions?
What is Security Operation Center (SOC)?
The security operations center (SOC), which is also called the information security of operation center (ISOC), is a centralized location where the information security team will monitor, respond, detect, and analyze cyber security incidents. The security team will respond to the scanning in all the security systems in real-time. A function of SOC is to prevent, detect, monitor, respond, and investigate cyber threats around the clock. The team SOC is charged with the protection and monitoring of the organization’s assets which includes the personnel data, intellectual property, brand integrity, and business systems.
Key Function Perform by the SOC:
Take Stock of Available Resources:
The SOC which is responsible for the two types of assets, the various applications, devices, and processes that are charged with the safeguarding, and also the defensive tools which are at their disposal that help to ensure those protections.
Preventative Maintenance and Preparation:
Even in the most well-equipped and agile response of those processes, it has no match for preventing those problems from occurring in the first place.
Preventative Maintenance:
The step includes for all the actions that are taken to make the successful attacks which is more difficult, it includes the regular maintaining and the updating of the existing systems, it updates the firewall policies, whitelisting, patching vulnerabilities, securing applications, and blacklisting.
Preparation:
The team members should stay informed on those of newest security innovations, latest trends in the cybercrime, and the development for the new threats on that horizon. This research will help to inform the creation of a security roadmap that will provide the direction for company cyber security that efforts will go forward, and the disaster recovery plan which will serve to ready the guidance in the worst-case scenario.
Continuous Proactive Monitoring:
The tools which are used by SOC will scan the network 24/7 to flag any of the suspicious activities or abnormalities. It monitors the network around the clock which allows the SOC that has to be notified immediately of the emerging threats, which gives them the best chance that to mitigate or prevent harm.
Alert Ranking and Management:
When the monitoring tool has sent issue alerts, it is one of the responsibilities of SOC to have a close look at each one of them, discard any of the false positives, it determines how aggressive any of the actual threats of what they could be into targeting.
Threat Response:
It has the action that most people will think of that when they will think of the SOC. When this incident is confirmed, the SOC will act as the first responder, it performs the actions like isolating endpoints or shutting down, terminating the harmful processes, and deleting files.
Recovery and Remediation:
The SOC will start the work to restore the systems and they recover any of the lost or compromised data. It may include restarting endpoints and wiping, reconfiguring the systems or in the case of a ransomware attack, it deploys the viable backups to circumvent of ransomware.
