Earlier this year, the SEC proposed a new set of rules on cybersecurity governance, which would require public companies to make appropriate disclosures of cyber risks and management procedures.

Although the amendments target the financial sector, it is one more evidence of the fact that cybersecurity is no longer a backburner component of business operations. It is a critical factor that can determine the destiny of all kinds of organizations, large or small.

Cybersecurity is a broad discipline, and it often seems overwhelming for an organization to know exactly how to approach its protection strategy. One area that should be of primary concern for any business is its public profile. In most cases, the early impression that a customer receives is through a company’s web site.

Website security is critical, not just because websites play a major role in a company’s brand and reputation, but also because the website is often a gateway to important and sensitive information collected from users and customers. When a site suffers a security incident, proper preparation can make all the difference between a minor inconvenience and a major crisis.

By taking proactive steps now to develop and implement a robust incident response plan, you empower your team to detect attacks early, minimize damages, and rapidly implement containment and recovery measures.

The Window of Exposure

Security incidents, like website impersonation, spoofing, or malicious code injection, require immediate action. There is a critical period between when the attack first occurs and when it is caught. According to Eran Tsur of Memyco, “organizations need a comprehensive solution that delivers instant attack detection and notifications, detailed forensics, and advanced mitigation strategies, ensuring protection during the crucial period between creating a fake site and removing it.”

That crucial period is known as the “Window of Exposure,” and it represents the greatest danger to your website visitors during an incident.

The longer the window remains open, the more damage can be inflicted. For example, if an attacker injects a keylogger as the method to steal credit card data, that code may sit undetected for days or weeks, stealing information from every customer who visits the checkout page in the meantime. Similarly, if a zero-day exploit is leveraged to install malware, visitors’ devices can be infected in the background without their knowledge while the site remains online.

Many organizations pay more attention to meeting compliance regulations (which are absolutely necessary) over focusing on minimizing their organization’s window of exposure to the many threats they face.

According to cybersecurity entrepreneur, Purandar Das, compliance standards might establish a baseline level of security, but because they lack specificity, they make organizations “implement generic or low-cost solutions that technically meet the requirement but fail to defend against sophisticated and evolving threats.” The goal, then, must be to minimize the window of exposure as much as realistically possible.

This requires having strong real-time monitoring in place to detect anomalies and trigger alerts quickly. An Intrusion Detection System (IDS) can safeguard your website with real-time protection, but you also need to integrate it into streamlined processes to enable your team to investigate and validate incidents rapidly so that containment measures can be enacted.

Core Steps to Develop an Incident Response Plan

According to cybersecurity executive Jonathan Trull, on responding to zero-day attacks, “gathering and analyzing threat intelligence is crucial to provide the necessary foundation for security teams to take calculated and intentional steps.”

1. Define Your Needs and Objectives

Consider factors, like your site’s architecture, data and traffic volumes, compliance requirements, recovery time and recovery point objectives, and reporting needs. This will inform the scale and scope of the plan. Define the types of incidents you aim to be prepared for, like malware infections, DDoS attacks, or data breaches.

2. Designate Roles and Responsibilities

With your goals clarified, detail the roles and responsibilities required to detect, investigate, contain, eradicate, and recover from incidents. Proactivity is important in addressing website security breaches, particularly spoofing attacks. Reactive methods, though essential, are not enough.

3. Create Communication Plans

Clear communication is vital during incidents, both internally and externally. Develop protocols for notifying impacted customers if data exposure occurs. Create escalation trees for informing higher levels of leadership as the severity of events warrants, and define methods for coordinating across teams, reporting findings, and sharing status updates.

4. Train Personnel

According to Verizon’s 2023 Data Breach Investigations Report, the human factor played a role in 74% of reported breaches. That underscores the importance of training personnel to prevent breaches, as well as understanding the key procedures of the incident response plan. Employees can be educated sentinels versed in identifying lurking threats.

5. Test Plans for Resilience

The true test of any incident response plan is an actual incident. Use intrusion tests and breach simulations to continually assess and refine your plan as well as to uncover any gaps in detection or containment measures that require improvement.

Strategizing for Disaster Recovery

While incident response plans address immediate security events, they are just one part of a larger disaster recovery strategy. This broader strategy looks beyond isolated incidents to consider how to build an organization’s long-term resilience.

According to a Mckinsey guide for business resilience, here are the key needs for achieving resilience:

  • Understand criticality
  • Evaluate the underlying technology
  • Recognize the corresponding business impact
  • Determine the risk tolerance of the organization and stakeholders

Disaster recovery takes a holistic view of potential crises that could disrupt business operations, from both cyber and physical sources. It involves thorough business impact analysis to identify the organization’s most critical assets, processes, and dependencies.

According to Memcyco, 81% of consumers stop engaging with a brand online after an attack. This is why continuous protection against website spoofing and other brand hijacking threats is crucial. Once you understand your business risks, then you must take steps to reduce them and ensure that these foundational elements can persist through disasters.

Tripwire’s Continuous Vulnerability Management is one such solution for achieving comprehensive visibility of your vulnerability profile, critical information with which you can solidify your disaster recovery strategy. For instance, performing regular secure data backups is key. There should also be alternative business processes defined that allow operations to continue even if certain systems are damaged.

Conclusion

While hoping for the best, effective readiness ensures your business is prepared for the worst. Paired with sound security practices and adequate cyber insurance, comprehensive incident response and disaster recovery plans provide defense-in-depth. Implement them now, before an emergency makes preparation impossible.

With proven strategies for minimizing business disruption and safeguarding customers, your company can operate with confidence knowing it can survive and thrive in the face of cyber adversity.
