Master The Art Of How To Respond To Cyber Attack

As we embrace the digital age, the number of serious cyber security threats continues to grow, making businesses more vulnerable than ever. Cyber-attacks can cripple an organization, leading to financial losses and tarnished reputations. This blog post will guide you through the process of responding to cyber attacks, from recognizing the threat to learning from the experience.

Introduction

Understanding Cyber Attacks

A cyber attack is a malicious attempt by an individual or organization to breach the information system of another individual or organization. Often, the attacker seeks some benefit from the data breach by disrupting the victim’s network. The types of cyber attacks are numerous and varied, and include methods like malware, phishing, brute force attacks, and denial of service attacks.

The 2020 Insider Threat Report by Cybersecurity Insiders showed that 68% of organizations felt that insider attacks were becoming more frequent, emphasizing the need for robust incident response strategies to address this growing threat.

Cyber Liability Insurance

Cyber liability insurance is designed to provide financial protection in the event of a cyber incident. It covers various aspects of cyber risks, including legal fees, forensic investigations, public relations efforts, and even potential fines and penalties. Not just the type of insurance is particularly important for businesses that store sensitive customer information or rely heavily on digital operations.

In the event of a cyber incident, it is essential to report the incident promptly to the appropriate authorities. The Internet Crime Complaint Center (IC3) is a valuable resource for individuals and businesses to report internet crimes and file complaints. The IC3 serves as a central hub for collecting and analyzing cybercrime-related information, which helps law enforcement agencies in their investigations.

Furthermore, it is important to involve local law enforcement offices when dealing with cybercrimes. They can provide invaluable assistance in investigating the incident, collecting evidence, and potentially apprehending the perpetrators. Working closely with law enforcement can increase the chances of bringing cybercriminals to justice and preventing future attacks.

Understanding Different Types Of Cyber Attacks

Each type of cyber attack has different characteristics, and understanding these can help in forming an effective response strategy. Malware, for example, includes harmful software such as viruses and ransomware that can infect a computer or network. Phishing involves fraudulent attempts to obtain sensitive data, often through deceptive emails. Brute force attacks involve trial and error methods to gain access to information, while denial of service attacks flood networks with traffic to render them unusable.

A survey by the SANS Institute in 2020 highlighted that 56% of organizations had fewer than five dedicated incident responders, suggesting that many organizations may be understaffed when it comes to handling cyber attacks.

Preparing For A Cyber Attack

Preparation is a critical aspect of managing the risk of cyber attacks. This involves establishing a dedicated response team, creating an incident response plan, using security controls and ensuring that staff members are educated about potential threats.

1. Establishing A Response Team

An efficient response team should consist of IT professionals who are experienced in dealing with cyber threats. This team will be responsible for identifying, containing, and eliminating threats, as well as recovering from attacks when they occur. Having a dedicated cybersecurity response team ensures that there is always someone available to respond quickly to threats, thereby minimizing potential damage.

2. Creating An Incident Response Plan

A robust incident response plan is a cornerstone of good cyber hygiene. This plan should outline the procedures to follow when an attack occurs, including the roles and responsibilities of the incident response team, communication strategies, and steps for mitigating damage. Additionally, the plan should also incorporate a recovery strategy to guide the organization in returning to normal operations after an attack.

In a survey by the SANS Institute in 2020, around 45% of respondents reported that less than 10% of their incident response processes were automated, indicating a potential gap in leveraging automation to respond effectively.

Training And Education About Cyber Attacks

Employees are often the weakest link in the cybersecurity chain, making it essential to educate staff members about different types of cyber threats and how they can contribute to prevention efforts. Regular training sessions can ensure that all staff members understand their role in maintaining cybersecurity.

Steps To Follow When A Cyber Attack Occurs

Once a security breach has been discovered, the organization should take the following immediate steps to limit the damage.

The IBM Cost of a Data Breach Report 2020 stated that it took an average of 280 days to identify and contain a data breach, indicating the challenges organizations face in promptly detecting and responding to cyber attacks.

Step 1: Identify The Attack

The first step in dealing with a cyber attack is to identify that an attack is occurring. This may involve detecting irregular activity on the network or receiving reports of suspicious incidents from employees. Once the attack has been identified, the response team should document all relevant information about the incident and respond to a cyberattack, including the nature of the attack, the affected systems, and the potential impact on the organization.

Step 2: Contain The Attack

After identifying the threat, the next step is to contain it to prevent further damage. This might involve disconnecting affected devices from the network, blocking malicious IP addresses, or changing user credentials on compromised accounts. The goal is to limit the attacker’s access to the network and reduce the spread of damage.

The IBM report also highlighted that breaches identified in less than 200 days cost an average of $1.12 million less than those identified after 200 days, underlining the financial benefits of swift response.

Step 3: Eradicate The Threat

Once the attack is contained, the response team should work to eradicate the threat from the system. This could involve removing malware, implementing patches, or updating antivirus software. It’s crucial to ensure that the threat or more active attack has been completely eliminated to prevent a recurrence of the attack.

Step 4: Recover From The Attack

The recovery process involves restoring affected systems and data, ensuring that the network is secure, and returning to normal operations. It’s important to monitor the system closely during this time to detect any signs of persistent threats. Additionally, steps should be taken to improve security measures and prevent future attacks.

The Ponemon Institute’s 2020 Cost of Insider Threats study found that involving an incident response team reduced the cost of a breach by $360,000 on average.

Step 5: Conduct A Post-Incident Review

After the situation has been resolved, the response team should conduct a post-incident review. This involves analyzing the incident to understand how the attack occurred, determining what worked well in the response, and identifying areas for improvement. Lessons learned from the attack should be used to strengthen the organization’s cybersecurity posture.

Long-Term Strategies To Prevent Future Cyber Attacks

In addition to immediate response measures, organizations should implement long-term strategies to prevent future cyber attacks. These include regularly updating and patching systems, using strong and unique passwords, limiting user access privileges, and regularly backing up and encrypting data. Furthermore, organizations need to keep abreast of the latest cyber threats and ensure their security measures evolve accordingly.

According to the 2020 Cyber Resilient Organization Report by IBM, organizations with a formal incident response plan experienced an average of $2 million less in breach costs than those without such plans.

Final Note

Cyber attacks are an unfortunate reality of the digital age, but with preparation and vigilance, organizations can effectively manage these risks. By understanding the nature of different cyber threats, establishing a capable response team, and implementing robust security measures, organizations can protect their valuable customer data and maintain their reputation.

in the face of cyber attacks. It is crucial for organizations to have a well-defined and tested incident response plan in place, as this will enable them to quickly and effectively respond to and recover from cyber attacks. By following the steps outlined above, organizations can minimize the impact of cyber attacks and prevent future incidents such attacks from occurring. Ultimately, cybersecurity should be seen as an ongoing process that requires continual monitoring, evaluation, and improvement to stay ahead of emerging threats.
