    Cyber Security Audits: Benefits, Best Practices & Checklist

    Small businesses are the backbone of all global economies, accounting for almost 99 percent of all private sectors. Yet, as a recent study from Symantec found, small businesses are also disproportionately targeted by cybercriminals. In fact, 62% of all cyberattacks in 2017 were aimed at companies with fewer than 500 employees. That is why it is essential for small business owners to take steps to protect their businesses from cyber threats. Various online IT security training courses for your employees can help you enhance your understanding of cyber threats and their solutions. Every organization is vulnerable to cybercrime, which is why a comprehensive cybersecurity strategy is critical for all businesses. One component of your overall strategy should be regular cyber security audits. This blog post will discuss the benefits of audits, best practices to follow, and a handy cyber security audit checklist to help you get started.

    What is Auditing in Cyber Security? 

    Security audit in cyber security is a process of assessing an organization's cyber security risks. It involves identifying and evaluating an organization's strengths and weaknesses based on its ability to protect itself from cyberattacks. Cybersecurity audits can be performed by internal audit cyber security or external auditors. External audits are often conducted by expert cyber security third-party organizations. Internal audit cyber security, on the other hand, is typically conducted by an organization's IT staff. Cybersecurity audits are important for businesses of all sizes, as they can help identify gaps in an organization's defenses and ensure that appropriate steps are taken to mitigate those risks. Cybersecurity audits can also help organizations keep up with the latest cybersecurity threats and trends.

    Types of IT Security Audits

    Information security audits are an important part of any organization's security program. They provide an independent, objective assessment of an organization's security posture and identify areas of improvement. There are several different types of information security audits, each with its strengths and weaknesses.

    1. Compliance Audits

    The most common type of security audit is the compliance audit. This audit assesses whether an organization complies with internal policies or regulations. Compliance audits are typically less expensive and less time-consuming than other audits. However, they may not comprehensively view an organization's security state. In addition, compliance audits cannot always identify security weaknesses that attackers could exploit.

    2. Penetration Audits

    The penetration test is another type of information security audit. Unlike compliance audits, penetration tests are designed to simulate real-world attacks and identify vulnerabilities that could be exploited. Penetration tests are generally more expensive and time-consuming, but they offer a more comprehensive assessment of an organization's security state. In addition, penetration tests can help to identify weaknesses in defenses that might be missed during a compliance audit.

    3. Risk Assessment Audits

    Risk assessments are another type of information security audit. Risk assessments focus on identifying potential threats and assessing the likelihood that those threats will materialize. While risk assessments can be useful in identifying potential security problems, they cannot always provide a complete picture of an organization's security. In addition, risk assessments are more expensive and time-consuming than other audits.

    Information security audits are a vital tool for any organization striving to improve its security state. The type of audit performed should be based on the needs of the organization and the resources available. Each type of audit has its advantages and disadvantages. By carefully selecting the right type of audit for their needs, organizations can ensure that they receive maximum benefits from their auditing efforts.

    Why is Auditing in Cyber Security Important?

    Auditing in cyber security is important for a number of reasons. First, it helps to identify potential security risks and vulnerabilities. By auditing systems and networks, organizations can identify weak points that attackers could exploit. Additionally, auditing can help in preventing data breaches by providing visibility into accessing and using data. Finally, auditing helps to ensure compliance with security policies and regulations. With auditing systems and processes, organizations can ensure that they adhere to best network security audit practices. As a result, auditing is critical in protecting systems and data from cyber threats.

    Cyber Security Audit Scope

    The scope of a cyber security audit varies depending on the size and needs of the organization being audited. CEH Certification Training focuses on audit practices that will help you strengthen the security state of your organization. However, there are six key areas that should always be included in an audit:

    1. Identify and assess the organization's current state of cybersecurity. This includes understanding the organization's business processes, technology use, and identifying gaps in their cybersecurity defenses. 
    2. Identify and assess the organization's risks. This includes understanding the types of threats they face, what assets are at risk, and how likely a particular threat will materialize. 
    3. Understand the organization's compliance obligations. This includes understanding relevant regulations or standards, such as the EU General Data Protection Regulation (GDPR) or the Payment Card Industry Data Security Standard (PCI DSS). 
    4. Identify and assess the organization's cybersecurity controls. This includes understanding what controls are in place to protect against each type of threat and assessing their effectiveness. 
    5. Identify any gaps in the organization's cybersecurity defenses. This includes identifying any weaknesses in their controls or any areas where controls are missing altogether. 
    6. Recommend actions to improve the organization's cybersecurity posture. This includes recommending specific controls or process changes that would help to reduce the overall risk to the organization.

    How to Conduct a Security Audit?

    A cyber risk audit is a comprehensive examination of an organization's security state. A security audit aims to identify weaknesses and recommend corrective measures to improve the organization's security. There are many different types of IT security audits, but all share a common goal: to improve the security of the organization.

    There are two main types of security audits: internal and external. Internal security audits are conducted by employees of the organization being audited. External security audits are conducted by independent third-party organizations. Both types of audits have their advantages and disadvantages. Internal audits are more efficient and cost-effective but may be less objective. External audits are usually more objective but can be more expensive and time-consuming.

    When conducting a security audit, there are three main steps: planning, execution, and reporting. The cyber security audit plan phase must involve identifying the goals and objectives of the audit and defining the cyber security audit scope and methodology. The execution phase should involve conducting the actual audit, which may include interviews, site visits, and documentation review. The reporting phase should involve writing a cyber security audit report that summarizes the findings of the audit and recommends corrective actions.

    Process of IT Security Audit

    IT cyber security audit frameworks are essential for any organization that relies on technology to conduct business. The cyber security audit template and process can help to identify vulnerabilities and potential risks and assess the effectiveness of existing security measures.  

    • The first step in an IT security audit is to identify the scope of the audit. This may include all aspects of the organization's IT infrastructure, or it may be focused on a specific area, such as network security.  
    • Once the scope has been determined, the next step is to collect data. This data may come from a variety of sources, including server logs, application data, and user activity reports.  
    • Once the data has been collected, it must be analyzed to identify potential security risks. This analysis may be conducted manually or with specialized software.  
    • Finally, once the risks have been identified, the auditor will develop recommendations for mitigating those risks. These recommendations may involve changes to existing security policies or the implementation of new security measures.

    Implementing these recommendations can help to improve the organization's overall security and reduce the likelihood of an attack.

    What is a Security Auditing Tool?

    A cyber security auditing software that automates the process of assessing the security of an information system. Cyber security audit tools can be used to scan for vulnerabilities, analyze firewall and intrusion detection systems, and monitor network traffic. They can also be used to perform regulatory cyber security audits & compliance tests. Cybersecurity audit tools can help organizations identify and address security risks efficiently and effectively. Many leading companies offer security auditing tools as part of their suite of cybersecurity products.
