III. THE ROLE OF REAL-TIME THREAT DETECTION IN CRITICAL INFRASTRUCTURE SECURITY
Real-time threat detection, which entails ongoing infrastructure monitoring for any cybersecurity threats, is InfraGuard's
primary role. Real-time detection is crucial for seeing threats before they have a chance to do serious damage because of the
complexity and size of contemporary critical infrastructure systems. To accomplish this, InfraGuard uses a variety of
monitoring instruments and methods.
A. Technologies for Real-Time Detection
Advanced cybersecurity technologies are used by InfraGuard to guarantee early attack detection. These consist of:
 Intrusion Detection Systems (IDS): These systems keep an eye on network traffic in order to spot any indications of
suspicious behavior or illegal access. When IDS tools identify possible threats, they send out alarms.
 Security Information and Event Management (SIEM) Systems: SIEM platforms collect and examine security information
from multiple sources to find known attack signatures or patterns of anomalous activity.
 Machine Learning (ML) Algorithms: ML is being used more and more in threat detection, assisting InfraGuard in
forecasting possible threats by using anomaly detection and historical data.
 Behavioral Analytics: To monitor and identify changes in the typical behavior of network users or devices, InfraGuard
incorporates behavioral analytics. These variations could be an indication of malevolent conduct.
B. Networks of Threat Intelligence
Threat intelligence networks, which compile information on worldwide cyberthreats, are utilized by InfraGuard. InfraGuard's
system facilitates quick reactions to possible threats by exchanging information about vulnerabilities, attack methods, and new
threats. By providing pertinent stakeholders with actionable intelligence, this cooperative strategy aids in staying ahead of
enemies.
IV. AUTOMATED REACTION: REAL-TIME THREAT MITIGATION
Being able to react swiftly and effectively is crucial once a threat has been identified. A major factor in lessening the effect of
cyberattacks on vital infrastructure is InfraGuard's integration of automated response systems. Automated response protocols
ensure quicker containment and recovery by reducing threats before human intervention is necessary.
A. Techniques for Automated Threat Mitigation
Among the automated response mechanisms offered by InfraGuard are:
 The process of “Network Segmentation” involves separating the compromised system or network segment from the rest
of the infrastructure after a threat has been identified. This stops the attack from moving laterally.
 Traffic Filtering: Firewalls and intrusion prevention systems (IPS) can automatically filter out suspicious or malicious
network traffic to prevent dangerous data packets from getting to vital systems
 Shutting Down Infected Devices: Automated systems have the ability to disconnect or shut down compromised devices in
the event of malware detection or system compromise, thereby preventing the attack from spreading.
 Alerting and Escalation: When necessary, InfraGuard's automated system escalates incidents to higher authorities and
sends out alerts to pertinent stakeholders. This aids in setting priorities for reactions to more complex or serious threats.
B. Incident Response and Recovery
InfraGuard offers incident response teams assistance in recovering compromised systems and data in addition to automated
mitigation. Critical infrastructure can quickly recover from an attack thanks to the system's ability to roll back to secure states
or restore lost data, which reduces downtime.
