You've encountered a cybersecurity breach from a remote employee. How can you prevent future compromises?

Assess the impact of the breach, isolate the employee system and activate your response plan. Also, inform concerned stakeholders of the unfolding events.

Institutions have to conduct periodic security audits and vulnerability assessments to identify and address potential weaknesses in their security infrastructure.

After discovering a cybersecurity breach originating from a remote employee at a midstream oil and gas company, the IT department led by Karen quickly assesses the impact. They conduct a thorough investigation to determine the extent of the breach, identifying compromised systems and data. Karen coordinates with various departments to understand how the breach affects operations, financials, and compliance. The assessment reveals that sensitive data was accessed, but no major operations were disrupted. By promptly evaluating the impact, Karen’s team can prioritize their response efforts, mitigate damage, and restore trust in the company's cybersecurity measures.

Após detectar uma violação cibernética cometida por um funcionário remoto, é crucial adotar medidas preventivas para evitar recorrências. Primeiramente, é necessário avaliar a extensão da violação: identifique quais sistemas foram comprometidos, quais dados foram acessados e o impacto potencial nas operações da empresa. Essa análise é essencial para formular um plano de resposta eficaz e direcionado. Além disso, é importante notificar as partes afetadas, sobre o vazamento dos dados, e pedir auxílio ao órgão regulador “Autoridade Nacional de Proteção de Dados (ANPD)”, A transparência durante o incidente ajuda a manter a confiança dos stakeholders e facilita a mitigação dos danos.

To prevent future cybersecurity breaches, from remote employees, implement the following strategies: 1. Regular Training: Conduct frequent cybersecurity awareness training for employee. 2. Multi-Factor Authentication (MFA): Ensure that MFA is enabled for all accounts that access sensitive company data. 3. Secure VPN Use:Require the use of a Virtual Private Network (VPN) for all remote connections to ensure that data transmitted over the internet is encrypted and secure. 4. Endpoint Security:Use endpoint security solutions that monitor devices for signs of malware. 5. Access Controls: 6. Regular Audits: 7. Incident Response Plan Develop and practice an incident response plan. 8. Device Management: 9. Security Software:

Enforce policies strictly and implement data and information security strategies to prevent reoccurrence. Do not gate keep policies. Disseminate far and wide across the organisation.

While policy dissemination and constant communication and training is important, a policy that is not encoded or embedded in the technology or enterprise management systems will be ineffective. Policies on paper should translate to technical controls around access to system information infrastructure and all that. It should be implemented technically for adequate security, DMZs, VPN and restrictions or quarantine where applicable in line with BYOD and other policies.

Following the breach, John, the Chief Information Security Officer at a midstream oil and gas company, realizes the need to update the company's cybersecurity policies. He reviews the existing policies and identifies gaps related to remote work. John drafts new policies that include stricter access controls, mandatory use of VPNs, and regular password updates. He also incorporates guidelines for secure handling of sensitive data and protocols for reporting suspicious activities. John presents these updated policies to senior management, and once approved, communicates them clearly to all employees, ensuring everyone understands their role in maintaining cybersecurity.

So, I’m guessing you’ve already trained your employees, including those that work from home or “anywhere”. It’s easy to say “more training” but maybe stop and wonder why, despite the training you’ve provided this happened. Was the training relevant? Was it engaging? Was it delivered in a way that employees could have had half an eye on emails/candy crush/the Olympics (ie online) so it didn’t have the impact you hoped. If you’re going to deliver make sure it ticked those boxes - relevant, engaging, impact.

Good! Training is your best bet on human risks or the human chain in the security stack. You have your administrative controls by way of policies and procedures, you have your technical controls by way of system user organizations and privilege demarcation for users, guests and admin, now you must train, train and re-train the most sensitive, weakest link on the chain of internal controls and cybersecurity -- PEOPLE.

I always advocate Operational Risk and Cybersecurity Risk training for new hires no matter the grade or level and periodic training for all employees. Conduct mock test to determine level of awareness and areas to concentrate on.

To prevent future cybersecurity breaches, Susan, the HR director at a midstream oil and gas company, initiates a comprehensive training program for all employees, focusing on cybersecurity best practices. She collaborates with the IT department to develop interactive training sessions that cover topics like recognizing phishing emails, securing personal devices, and safeguarding company data. Susan ensures that the training is mandatory for all employees, including remote workers. By enhancing employees' cybersecurity awareness and skills, Susan helps create a more resilient organization, capable of identifying and responding to potential threats effectively.

One thing I have found helpful is by providing an ongoing cybersecurity training to educate employees about phishing, social engineering, and other common attack vectors.

Dave, the IT manager at a midstream oil and gas company, takes immediate steps to secure the company's networks after the breach. He implements advanced firewall protections, intrusion detection systems, and multi-factor authentication for all remote access points. Dave also ensures that all software and systems are regularly updated with the latest security patches. He collaborates with a cybersecurity firm to conduct regular penetration testing to identify and address vulnerabilities. These measures significantly strengthen the company’s network security, reducing the likelihood of future breaches and protecting sensitive data.

Companies have to ensure that remote employees use a secure VPN to encrypt their internet connection, protecting data in transit.

Continuous monitoring and audit of internal controls and operational risk management is a good way to go. What does not get monitored does not get enabled or enforced.

Lisa, the Chief Technology Officer at a midstream oil and gas company, enhances the company's cybersecurity posture by implementing continuous monitoring systems. She deploys sophisticated monitoring tools that provide real-time alerts on suspicious activities and potential breaches. Lisa's team establishes a Security Operations Center (SOC) to oversee these systems 24/7, ensuring immediate response to any threats. By continuously monitoring network traffic and system activities, Lisa can quickly detect and neutralize potential threats, maintaining the integrity and security of the company’s digital assets.

Given the recent cybersecurity breach involving a remote employee, it's crucial to enhance our security measures and ensure that all team members, regardless of their location, adhere to the highest standards of security by conducting regular employee Training and Awareness that includes Cybersecurity Training: Provide regular training sessions focused on recognizing phishing attempts, avoiding social engineering attacks, and practicing good cybersecurity hygiene. Incident Reporting: Educate employees on how to report suspicious activities and potential security incidents promptly.

Incident response should be automatic or automated: quarantining, investigation, detection, eradication and recovery from last back up. This should be test runner over and over again and ready to go once the need arises. DMZs are so important.

In this day and age incidents are going to happen no matter how robust the process is. Our goals should be to minimize the frequency and recover as quickly as possible while also minimizing impact. One way to do this is to have a strong response playbook that is frequently updated so that the team is ready to respond!

It's important to ensure lessons learnt translate to good feedbacks and feedforwards for effective planning, incident response, disaster recovery and business continuity management.

Assess: Find out the reason and conduct root cause analysis of the security breach Notification: Notify the relevant bodies based on your industry and mandatory breach requirements( if applicable) Remediation: Ensure that the reason for this breach cannot be replicated by the staff again. So, if the breach is caused due to failure of a good security practices by the staff, provide the additional assistance/training to the employee Monitoring and ongoing security training : Awareness training and monitoring will ensure any security incidents are recorded and acted swiftly Support: Provide the support to the affected staff always. This will build trust culture and no blaming games will be played. It improves morale of the team

Ensure all systems are accessed remotely only through a VPN and that passwords are updated regularly, ideally on a monthly basis. After resolving the incident, it would be good to conduct a post-resolution analysis to review the cause of breach. This will help in addressing all vulnerabilities and prevent future occurrences.
