Security control

Controls are the safeguards to prevent incidents, detect problems or correct them.

In the realm of cybersecurity, security control is essentially a safeguard or countermeasure designed to protect information systems and data from threats. Here's a breakdown:  

  • Purpose:
    • Security controls aim to reduce risks to an acceptable level.  
    • They protect the confidentiality, integrity, and availability (CIA triad) of information.  
  • Types:
    • Physical Controls: These are tangible measures, such as locks, fences, security guards, and surveillance cameras, that protect physical assets.  
    • Technical Controls: These involve technology-based solutions, like firewalls, antivirus software, encryption, and access controls.  
    • Administrative Controls: These consist of policies, procedures, and guidelines, such as security awareness training, risk assessments, and incident response plans.  
  • Functions:
    • Preventive Controls: These aim to stop security incidents from happening in the first place.  
    • Detective Controls: These are designed to identify and detect security incidents that have already occurred.  
    • Corrective Controls: These focus on minimizing the impact of security incidents and restoring systems to normal operation.  

In essence, security controls are vital for any organization seeking to protect its valuable assets from a wide range of security threats. 1

Stop-or-go sampling

Stop-or-go sampling, also known as sequential sampling, is a method used primarily in auditing to determine whether a population (like a set of financial transactions) contains a high number of errors. Here are the key points about stop-or-go sampling: Purpose : The main goal is to minimize the amount of sampling needed to reach a conclusion about the population. This method is particularly useful when the expected error rate is low Process : Initial Sample Size : Auditors start with an initial sample size based on the population size and acceptable error level. Evaluation : The initial sample is evaluated for errors. If the number of errors is below a predetermined threshold, the sampling stops, and the population is considered acceptable. Continuation : If the number of errors exceeds the threshold, the sample size is increased, and further samples are evaluated until a conclusion can be drawn Advantages : Efficiency : R...

Compliance risk

Compliance risk , also known as  integrity risk , refers to the potential for an organization to face  legal penalties ,  financial losses ,  reputational damage , or  operational disruptions  due to failure to comply with applicable  laws ,  regulations ,  industry standards , or  internal policies . Definition Compliance risk , also known as  integrity risk , arises when an organization fails to adhere to the legal, regulatory, and ethical standards relevant to its operations. This type of risk can impact an organisation’s earnings, capital, and reputation, potentially leading to  fines ,  lawsuits ,  business disruptions ,  loss of licenses , or  government sanctions . Key Elements Legal and Regulatory Requirements : Compliance risk includes failure to adhere to local, national, or international laws and regulations, such as those related to  financial reporting ,  data p...

Discovery sampling

Discovery sampling is a statistical auditing technique used to detect the presence of a specific characteristic or attribute within a population, especially when the occurrence rate is expected to be very low. Here are the key points about discovery sampling: Purpose : The main goal is to identify whether at least one instance of the characteristic or attribute exists in the population. This method is particularly useful for detecting rare events, such as fraud or errors Process : Define Objective : Determine what you are trying to discover (e.g., unauthorized transactions). Set Parameters : Establish the tolerable error rate (often set to 0% for critical issues) and the confidence level (e.g., 95% confidence that the sample will include at least one instance if it exists). Sample Size : Calculate the sample size needed based on statistical tables or software. Evaluate Sample : Examine the selected sample for the characteristic or ...
