1. Introduction
Considering the current Modern Evolving world, reactive measures would no longer be a secure option to protect assets. By following reactive measures, we could mitigate the risk only after the attack has occurred. This might end up in loss of data or high impacts on organizations, like reputational damage, Loss of Availability of resources and financial losses. Since the technology has developed, Attackers has also advanced with their attack strategies by Implementing Artificial Intelligence, Machine Learning Algorithms, Automation tools and Social Engineering Techniques, Attackers are taking advantage of the limitations of Traditional Reactive measures were getting succeeded in their attacks. So, the transition to proactive measures has become crucial because Proactive measures Monitor, Detect, Prevent and regularly collect the automated responses and react to them to analyze and mitigate the Risks. Proactive measures focus on protecting assets by performing Threat Analysis, Risk Assessments, Regular Monitoring and implementing Robust Security tools that detect and prevent incidents before they cause potential harm. Along with providing security to the Assets, these measures also reduce the impacts of incidents and the likelihood of incidents. Also, considering the Regulatory Compliance requirements and Industry standards are more emphasizing the Need for Proactive Measures. This Paper provides the Limitations of Reactive measures, explains structured Frameworks of proactive measures and outlines the effectiveness of implementing these measures in organizations. By Examining various advanced Tools, Technologies and frameworks, this research provides the importance of proactive measures in improving organizations' defence security, which will reduce the likelihood of Threats and their Impacts on the organization

2. Main Body
A. Problem statement
Due to the increase in cyber-attacks, such as DDoS attacks, Ransomware attacks, Advanced Persistent attacks (APTs), SQL Injection, cross-site scripting, Ransomware attacks, Insider Threats and many others, the Reactive measures approach is no longer a good secure option. Reactive measures will greatly impact because they require time to detect and respond to incidents. Here are a few key issues that support the limitations of Reactive Measures:

• Failure to detect the threats: Even Though Attackers implanted critical malware in the system, we could not detect the vulnerabilities because we followed reactive measures, which will lead to incidents.
• Amplified impact: Due to delay in responding to the incidents the threats to disrupt the services which might cause loss of availability to the services and might also result in financial losses.
• Unpreparedness: Reactive measures processes will not have preventive measures. These measures could not Analyze or predict the emerging threats which results the systems in vulnerable states easy to exploit vulnerabilities. A few more shortcomings for Reactive measures are due to the Increased latest Cyber Threats.
  
  

Here are a few of them:

• Advanced attacks: polymorphic malware, zero-day Vulnerabilities and fileless attacks cannot be detected through traditional strategies.
• Increased attack surfaces: The Increased adoption of IoT devices, cloud Computing and Hybrid and remote work environments has Increased the attack surface, which is making it harder to protect through Reactive measures.
  
  

Traditional Firewalls, Tools and Techniques are harder to detect and respond to promptly, which can lead to financial losses. In Reactive measures, there is a possibility for Human errors in detecting and Responding to a few Incidents. Majorly these issues show the importance of implementing proactive measures.

B. Solutions
2.1. Proactive incident response measures
Threat Hunting- Threat hunting is a proactive approach that involves actively monitoring and scanning the organization's network infrastructure to detect vulnerabilities, malware or any malicious activities that might threaten the asset. In this approach, these threats are detected by robust automated tools. With the combination of Expert teams, Automated Tools and Frameworks, it is possible to collect information on systems and analyze the system security.

2.2. Processes: Here are a few Processes for Threat Hunting
Hypothesis-Driven Hunting- In this method, Potential Threats are analyzed Using the MITRE Attack framework, which provides the details of TTP Tactics, Techniques and Procedures. By analysing the known patterns and signatures, Threats can be detected.
Indicator- Driven Hunting-In this method, threats are analyzed based on Forensic analysis of past attacks to find hidden threats.
Data Driven Hunting - Using Data Analytic techniques, we can analyze the Threats and the Risk appetite. We can also compare various Data sets with information regarding the vulnerabilities and predict the significant Threats.Tools and Techniques: SIEM Tools, SOAR Tools, EDR Tools, Velociraptor, OS Query and Suricta to support Threat Hunting and antivirus software are effective in finding threats.

Regular Monitoring: Usage of Advanced Technologies-Implementing AI Tools and utilizing Machine Learning Algorithms makes regular monitoring easy. Tools will perform continuous monitoring and trigger alerts if there are any attack patterns, which helps troubleshoot and mitigate risks.

• Telemetry data: Advanced technology software and tools collect Logs regularly, which provide details of traffic flow and help act as surveillance security for early detection of threats.
• Security operations centre: By Building a security operations Team to Monitor the network 24*7. Even though we deploy Robust automated tools for regular monitoring, detecting, collecting logs and preventing Threats. But there are also chances for false positives. So, it is essential to involve Human checks for Deep Analysis and Responding to the Alerts.
• Automated mitigation: Pre-emptive Playbooks, Automated response not only helps mitigate the issue but also reduces the recovery time. This automated mitigation process helps detect threats and prevents them from occurring, reducing the manual interference needed to resolve attacks.

Challenges in Implementing Proactive Measures-Though by Implementing Proactive measures organizations could improve their security posture, there are some challenges in adopting the proactive incident Response Framework. There is a need for Deploying Robust Security tools for Endpoint security and real-time monitoring to prevent Insider Threats. To deploy these tools, Companies should Invest highly. Since these are advanced tools, companies should recruit highly skilled professionals or provide training to employees and educate them on the usage of these tools.

False Positives- There is a chance of getting False Positives, for which Human intervention is required for deep analysis.

Compatibility issues may arise because a few legacy systems are incompatible with the advanced tools.

Overcoming Challenges: Deploying Managed Detection and Response tools can reduce implementation costs. As per the company budget deploying the tools as per company requirements one after the other.
