  2. Check for updates regularly and install them as soon as they become available.
  3. Schedule routine scans on the system and removable media to detect and remove potential threats.

Following these steps can help keep your system secure and protected from cyber threats.

Larger organisations can configure workstations to communicate update status to a centralised server. This server then distributes updates automatically when needed. Adhering to a regular patching cadence is vital, as research has found that organisations that fail to do so are seven times more likely to become a target of ransomware.

Regular internal and external vulnerability scans are essential for recognising possible future security challenges and incidents and sustaining security operations.

Strong access controls

Strong access controls are achievable by preventing unauthorised access, data breaches, and insider threats. Multi-factor authentication (MFA) is a security system that combines two or more verification methods, such as a password, a token, or biometric data, to authenticate users.

The principle of least privilege dictates that employees should only be granted the permissions necessary to fulfil their duties.

Regularly auditing permission rights and monitoring user activity in the cloud can help ensure that your organisation’s access control policies and multi-factor authentication requirements are up-to-date and effective.

Data classification

Developing a data classification system is essential for prioritising and protecting data following its level of importance. Data classification generally encompasses the following categories:

  1. Public
  2. Internal
  3. Confidential
  4. Secret

Implementing data classification policies ensures that data is accurately identified, labelled, and protected. The steps for implementing a data classification system include:

  1. Identifying and labelling data
  2. Formulating data classification policies
  3. Educating employees
  4. Monitoring data access.

Encrypt sensitive data

Prevention of unauthorised access to confidential data and maintenance of trust in your organisation can be ensured by encrypting sensitive data. Encryption is a process of securing data using algorithms. It converts readable data (plain text) into an unintelligible format (ciphertext). To decrypt the data, a secret key is used.

Implementing end-to-end encryption methods, such as Transport Layer Security (TLS) or Secure Socket Layer (SSL), ensures that data is encrypted before leaving the device. This ensures that data is only decrypted upon reaching its intended recipient. Employing industry-standard encryption algorithms guarantees the utmost level of security for data.

Managing encryption keys is paramount for ensuring the efficacy of encryption, so it is essential that keys are stored securely, access to them is restricted, and they are regularly rotated and updated.

Regular penetration testing to identify gaps and validate security measures

Identifying security gaps and vulnerabilities in your organisation’s security controls can be achieved through regular penetration testing. A penetration test is an information security audit intended to simulate potential attacks and identify any vulnerabilities that could be exploited.

By performing regular vulnerability assessments and penetration tests, organisations can take a proactive stance on their security by recognising security deficiencies and resolving vulnerabilities before they become critical.

Remediation of any vulnerabilities discovered during a penetration test and periodically reviewing and updating the vulnerability assessment process ensures that your organisation’s security posture remains strong.

Define secure configuration baselines

Establishing secure configuration baselines can ensure that systems and devices are set up securely. Secure configuration baselines are a set of recommended configuration settings that define the standard, approved configuration of a system or information system, including security configurations that aim to reduce vulnerabilities and to protect systems against potential threats.

Adhering to industry best practices and standards, such as the Center for Internet Security (CIS) Benchmarks, provides a comprehensive set of recommended configuration settings that define a system’s standard, approved configuration or information system.

Regularly updating secure configuration baselines ensures that systems and devices remain secure and up to date.

Logging and monitoring controls

Detecting and responding to security threats in real time can be achieved by implementing logging and monitoring controls, including the ability to monitor network traffic. Maintaining records of network activity is critical for post-incident investigation and adherence to industry standards.

  • Efficiently analysing the collected data
  • Consistently monitoring network activity
  • Timely detection and response to potential threats
  • Reducing possible damage and safeguarding digital resources

Secure remote access

Maintaining network integrity and protecting data can be achieved by ensuring secure remote access. A VPN is a secure, encrypted connection between a user’s device and an organisation’s network. It establishes a private tunnel through the public internet and enables remote workers to securely access company resources as if they are connected to the office network.

Comprehensive Cyber Security Audit Checklist for 2023

Remote access solutions can be secure with the use of:

  • Virtual Private Network (VPN)
  • Remote Desktop Services
  • Multi-Factor Authentication
  • Zero-Trust Security models

These methods offer organisations powerful ways to control which user accounts can access their resources. Establishing secure connections guarantees that personnel can securely access the system’s information resources.

Develop and test an incident response plan

Effectively managing and mitigating security incidents can be achieved by developing and testing an incident response plan. An incident response plan is a protocol that details the steps to be taken during a cyber security incident. A comprehensive incident response plan in place can assist organisations in rapidly recovering from cyber attacks and reduce potential harm.

Being prepared and knowing the necessary steps to take in the event of a security or data breach, ensures that all parties are aware of their responsibilities. Having a well-organised incident response plan is essential for effective security management.

Perform backup and recovery testing

Ensuring data restoration and business continuity can be achieved through regular backup and recovery testing. Backups are essential for restoring data during a cyber security incident, system failure, or other disruptive events.

However, it is equally important to test the backup and recovery process to ensure that the stored data is complete, accurate, and free of corruption. Through regular testing, potential issues such as inadequate storage capacity, hardware failures, or software bugs can be identified and addressed proactively, allowing for seamless data recovery after an incident and reducing downtime and potential losses.

Continuous employee education and awareness

Building a security culture within your organisation can be achieved through continuous employee education and awareness training. Employee awareness training enables personnel to identify potential cybersecurity threats themselves, react appropriately to security breaches, and cultivate a culture of cyber security awareness.

Continuous employee education and awareness have numerous benefits, such as:

  • Increased knowledge and skills
  • Adaptability
  • Contribution to the organisation
  • Cost-effectiveness
  • Employee engagement and satisfaction

Conduct third-party security reviews

Assessing vendor security practices and mitigating potential risks can be achieved by conducting third-party security reviews. Third-party security reviews are assessments external entities conduct to evaluate the security areas and practices of a company’s third-party vendors or partners.

These reviews strive to identify any potential security risk or vulnerabilities in the third-party’s systems or processes, ensuring that the company’s data and assets are safeguarded.

Privilege access management

Controlling and monitoring access to sensitive systems and data, including operating systems, can be achieved by implementing privilege access management. Privileged users, such as system administrators, database administrators, and other users with elevated privileges, have access to sensitive systems and data.

Access control measures, such as authentication, authorisation, and access control lists, should be implemented to protect sensitive information. Monitoring access to sensitive systems and data can be achieved through logging user activity, utilising audit trails, and deploying intrusion detection systems.

Ensure Mobile device management

Balancing productivity and security for mobile devices can be achieved by establishing a mobile device management policy. Remote management is essential for enforcing security policies, monitoring device usage, and wiping data from lost or stolen devices.

Implementing explicit regulations for mobile device management ensures that employees understand their responsibilities in protecting confidential information.

Secure wireless networks

Protecting data and maintaining an organisation’s security posture can be achieved by securing wireless networks. Implementing encryption and authentication protocols, such as WPA2-PSK (Wi-Fi Protected Access 2 Pre-Shared Key) and WPA3 (Wi-Fi Protected Access 3), can help ensure the security of wireless networks.

Utilising multi-factor authentication and segmenting networks provides an additional layer of protection by ensuring that only authorised users can access the network.

Deploy email security controls

Protecting against cyber attacks and safeguarding sensitive information can be achieved by deploying email security controls.

Email encryption is a security measure that safeguards confidential information from unauthorised access by rendering the content indecipherable to anyone without the decryption key.

Email authentication is the process of verifying the authenticity of emails sent from a domain. Email filtering is essential for detecting and blocking malicious emails before they reach the recipient’s inbox.

Restrict removable media usage

Preventing data loss and unauthorised access can be achieved by restricting the use of removable media. Organisations should restrict the use of:

  • USB drives
  • External hard drives
  • CDs
  • DVDs
  • Other forms of removable media.

Implementing policies and processes to limit the use of removable media, such as disabling USB ports, encrypting removable media, and monitoring the use of removable media, can help protect sensitive information and ensure compliance with regulations.

Compliance with Industry Regulations and Standards

Avoiding penalties and maintaining a strong security posture can be ensured through compliance with industry regulations and standards. Compliance audits are the most common type of security audit, designed to demonstrate compliance and guarantee adherence to industry regulations and standards.

Adhering to relevant national and international regulatory requirements, such as GDPR or HIPAA, is essential during information security audits. However, compliance audits may not provide a comprehensive view of an organisation’s security state and may not be able to identify all security weaknesses that attackers could exploit.

A cyber security audit checklist allows organisations to assess their infrastructure, systems, and processes thoroughly. This tool helps identify potential security gaps and address vulnerabilities or known issues.
