How to Implement a Security Incident Management Framework

Uncontrolled network security incident activity can grow into a greater issue, which could result in data breaches, excessive charges, or system disruptions. However, organizations can reduce losses, address exploited vulnerabilities, restore services and operations, and reduce the risk of subsequent incidents by acting swiftly after an occurrence.

IT security experts claim that because of the near-constant barrage of threats, they now spend so much time dealing with unanticipated catastrophes that they need more time to create more strategic projects and initiatives. That kind of incident-driven security approach is no longer viable, given the size and sophistication of today's End Point Security.

Organizations require a structured plan of action that will enable a consistent and dependable reaction to emerging risks rather than continuously responding to attacks with impromptu mitigation measures. Due to their capacity to react to threats swiftly and effectively, studies show that organizations with thorough incident management procedures save an average of more than $1 million with the help of IT services company like databytes Consulting on the total cost of a data breach.

Acquiring Knowledge of Security Incident Response

Manage the whole life cycle of your network security issues with Security Incident Response (SIR), from early analysis to containment, eradication, and recovery. With the use of analytically driven dashboards and reporting, Security Incident Response gives you the ability to gain a thorough picture of the incident response operations carried out by your analysts.

Security automation and orchestration for effective and precise incident response are made possible through built-in connectors with third-party cyber security solutions like Databytes Consulting.

Creating an incident response plan can be done without starting from scratch. End Point Security which can be customized to an organization's specific preferences, has been created by various standards organizations and cybersecurity businesses. The international standard ISO/IEC 27035 is frequently cited as one of the best examples. It defines the five-step incident management method in the following document, which the International Organization for Standardization and the International Electrotechnical Commission jointly published:

Plan & Prepare

·         Create a high-level document defining broad methods for handling network security issues in collaboration with IT employees and other stakeholders.

·         Create a capable incident response team that is in charge of handling all cybersecurity incidents.

·         Create a comprehensive system of classification for rating and ranking instances.

·         Implement a program for security awareness education.

Observe and Report

·         Check for signals of an attack using firewalls, interruption prevention systems, antivirus software, and other tools.

·         Examine log data from different systems and gadgets.

·         Record all activities, times, dates, contacts, and general observations in a special incident tracking system.

Assess and Make a Decision

·         To decide if the occurrence represents a real network security danger or a false alarm, evaluate all the data gathered in the preceding phase.

·         Based on the classification system created in the first phase, give real threats the highest priority.

·         Assign incident response tasks and suggested processes to the right people.

Actions

·         To stop an attack and prevent further damage, disconnect the afflicted servers from the network, isolate the vulnerable systems, and make disc images and backups.

·         To collect pertinent metrics, disseminate incident reports, disconnect infected systems, do vulnerability checks and other tasks, and use automated operations whenever possible.

·         Stop communicating with servers that control C&C.

·         The malware must be removed from all impacted systems.

·         Eliminate accounts or backdoors that the attackers left behind.

·         Apply security updates to impacted systems.

Our Opinion on Security Incident Management

1.     Critical Analysis

There will be occurrences. Don't rely on pre-prepared remarks. They are too general and simple to disregard. Instead, create your own customized incident use cases to reduce confusion and reaction time for your organization. Analyze, monitor, and review incident response outcomes often. The same attack vector may re-victimize you without a thorough awareness of incident trends and patterns.

Establish channels and procedures for communication before a crisis occurs. Avoid waiting until you're in a panic. To stay ahead of incoming threats, work together and share information with other organizations.

2.     Impact and Outcome

A formal process of planning, identification, analysis, containment, elimination, recovery, and post-event activities is required for effective and efficient incident management.

This blog will guide you through the process of creating an effective incident response program that is scalable and systematic for your firm.

Insights Learned

·         Conduct cyber forensics to learn how an incident occurred and how it could be avoided in the future.

·         The entire incident response procedure should be documented. Hold meetings with the incident response team to review the decisions and how they could be improved.

·         Determine any potential problems and modify your awareness-raising strategies accordingly.

Conclusion

Whether you're ready or not, network security events will nonetheless occur. Data breaches and ransomware are just a couple of the hazards that are top-of-mind for all organizations. It might save you a lot of time and work in the long run to take the time upfront to establish your response strategy. When an issue occurs, act quickly to find a solution. Instead, plan ahead by selecting your response team, improving your response processes, and monitoring KPIs.

Plans for security incident management can help businesses respond to threats swiftly and minimize damage, but putting these plans into practice can be difficult for understaffed IT teams. IT services like Databytes Consulting can lessen the burden of creating a response strategy by including incident management in our portfolio of security services. To find out more, contact them.
