What is BAU in Cyber Security? A Peek into Everyday Operations


I have spent countless hours working behind the scenes to ensure that businesses stay protected from malicious threats. The world of cybersecurity is often perceived as a foreign and elusive concept, especially for individuals who are not actively involved in the field. However, what goes on behind the curtain is not as complicated as one might think. In this article, I will provide an exclusive sneak peek into what Business as Usual (BAU) operations look like in cybersecurity. From monitoring of systems to incident management, you will get an insight into the daily routine of a cybersecurity expert. So, let’s dive in!

What is BAU in cyber security?

BAU in cyber security stands for Business As Usual which is an essential component of the overall cybersecurity strategy and refers to the standard set of processes and procedures necessary to maintain the day-to-day operations of an organization while minimizing the risk of cyber-attacks. As cyber threats continue to evolve daily, the importance of a robust BAU plan cannot be overemphasized, particularly for small and medium-sized companies.

Below are some key activities that make up the BAU in cybersecurity:

  • Regular software updates and patching to address vulnerabilities and security gaps in existing systems.
  • Implementing and monitoring firewall rules and intrusion detection systems to safeguard the network against unauthorized access or malicious traffic.
  • Maintaining and enforcing security policies and procedures, which include multi-factor authentication and password complexity requirements to ensure employees comply with cybersecurity best practices.
  • Conducting continuous vulnerability assessments, penetration testing, and security risk assessments to identify areas of weakness and proactively mitigate threats before they lead to a breach.
  • Regularly backing up data to secure locations and verifying that data recovery processes are in place in the event of an incident.
  • By implementing these BAU practices, small and medium-sized companies can help protect their digital assets, minimize the impact of cyber-attacks, and maintain business continuity. It is critical to review, update and practice the plan regularly to ensure continued effectiveness and keep up with changing cybersecurity threats.

    ???? Pro Tips:

    1. Always keep yourself updated with the latest BAU trends and practices in cybersecurity.
    2. Regularly perform vulnerability assessments to identify potential security gaps in your BAU operations.
    3. Develop a robust incident response plan to address any security incidents during BAU operations.
    4. Conduct regular training sessions for your employees to ensure they understand the importance of BAU security practices and their role in it.
    5. Collaborate with external cybersecurity experts to gain insights into the latest BAU threats and enhance your security practices accordingly.

    Defining Business As Usual in Cyber Security

    Business As Usual (BAU) in cyber security refers to the standard operating processes, procedures, and protocols that are employed to ensure the confidentiality, integrity, and availability of information and systems within an organization. It encompasses the entire spectrum of activities, including prevention, detection, response, and recovery from cyber threats. Whenever a company adopts a BAU approach, it means that it has established a proactive and continuous mechanism for identifying, managing, and mitigating cyber risks.

    The Importance of BAU in Small and Medium-Sized Companies

    Small and medium-sized companies are vulnerable targets for cyber threats due to their limited budgets, resources, and expertise. According to a recent Cybersecurity Ventures report, around 43% of cyber attacks target small businesses, and 60% of them go out of business within six months of the attack. Therefore, it is vital for these companies to embrace the BAU framework as a critical component of their operations. It enables them to minimize the impact of cyber threats, protect customer data and privacy, and ensure business continuity. In addition, adopting a BAU approach can enhance customer trust and brand reputation, which are essential for long-term business sustainability.

    Threats and Risks Addressed by BAU

    BAU is designed to address a broad range of cyber threats and risks that can impact an organization’s information and systems. These threats include:

    • Malware and viruses
    • Phishing and social engineering attacks
    • Denial-of-service attacks
    • Ransomware attacks
    • Advanced persistent threats

    Moreover, BAU also addresses the following risks:

    • Data breaches and theft
    • System and network downtime
    • Fines and penalties for non-compliance with data protection and privacy regulations
    • Reputational damage

    BAU Frameworks and Best Practices

    The BAU framework encompasses a set of best practices that organizations can follow to ensure effective management of cyber risks. The following are some examples of BAU frameworks and practices:

    • Developing and implementing a comprehensive information security policy that outlines roles and responsibilities, risk assessment, incident response, and disaster recovery plans.
    • Performing regular vulnerability assessments and penetration testing to identify weaknesses in systems and networks.
    • Implementing access controls and user authentication mechanisms to ensure that only authorized personnel have access to sensitive data and systems.
    • Providing continuous security awareness training to employees to help them detect and respond appropriately to phishing attacks, social engineering tactics, and other cyber threats.
    • Backups and recovery mechanisms to ensure that data can be quickly restored in the event of a cyber attack or system failure.

    Implementing BAU in Cyber Security: Challenges and Solutions

    Implementing BAU in cyber security can be challenging, especially for small and medium-sized companies with limited resources and expertise. Some of the common challenges include:

    • Lack of budget
    • Lack of in-house expertise
    • Resistance to change
    • Lack of support from senior management

    One solution to addressing these challenges is to outsource BAU services to a managed security service provider (MSSP). MSSPs can provide cost-effective and flexible cybersecurity solutions that can be customized to meet the specific needs of an organization. Furthermore, MSSPs have certified experts who are knowledgeable about the latest threats and mitigation strategies, enabling organizations to benefit from their expertise without having to invest in expensive in-house resources.

    Measuring Success and Effectiveness of BAU in Cyber Security

    Measuring the success and effectiveness of BAU in cyber security is crucial to ensuring ongoing improvement and maintaining compliance with regulatory requirements. Metrics that can be used to measure the success of BAU include:

    • Increase in security posture maturity
    • Reduction in the frequency and severity of data breaches and cyber attacks
    • Decrease in system and network downtime
    • Increase in employee security awareness and compliance

    Furthermore, measuring the effectiveness of BAU allows organizations to identify areas that need improvement and to adjust their security posture accordingly.

    The Future of BAU in Cyber Security

    As companies continue to adopt digital transformation strategies, the threat landscape is expected to evolve and become more complex. Therefore, implementing BAU in cyber security will remain a critical component of any organization’s risk management strategy. In addition, new technologies, such as artificial intelligence and machine learning, will play a more significant role in BAU, enabling organizations to detect and respond to threats more efficiently and effectively. However, organizations should embrace a collaborative approach to cybersecurity, working together to share threat intelligence and best practices to stay ahead of the ever-evolving threat actors.
