Securing Your Digital Approval Processes: Best Practices
In today's digital landscape, organisations are increasingly relying on digital approval processes to streamline operations, improve efficiency, and reduce costs. However, this shift also introduces new security risks. Digital approvals often involve sensitive data, and a compromised system can lead to significant financial losses, reputational damage, and legal liabilities. Implementing robust security measures is crucial to protect your organisation and maintain trust. This article outlines best practices for securing your digital approval processes.
1. Implementing Strong Authentication
Authentication is the first line of defence against unauthorised access. Strong authentication methods verify the identity of users before granting them access to the approval system.
Multi-Factor Authentication (MFA)
MFA requires users to provide two or more verification factors, such as something they know (password), something they have (mobile phone), or something they are (biometric data). This significantly reduces the risk of unauthorised access, even if a password is compromised. Implementing MFA is a crucial step in securing your digital approval processes. Consider what Approvals offers in terms of MFA integration.
Common Mistake: Relying solely on passwords for authentication. Passwords can be easily compromised through phishing attacks, brute-force attacks, or weak password practices.
Example: A user attempts to approve a high-value invoice. In addition to their password, they are prompted to enter a code sent to their mobile phone via SMS or a push notification from an authenticator app.
Role-Based Access Control (RBAC)
RBAC restricts access to sensitive data and functions based on a user's role within the organisation. This ensures that users only have access to the information and actions necessary to perform their job duties. This principle of least privilege minimizes the potential damage from a compromised account.
Common Mistake: Granting excessive permissions to users. This can lead to accidental or intentional misuse of data.
Example: An accounts payable clerk has access to approve invoices up to a certain amount, while a senior manager has the authority to approve larger invoices. This prevents unauthorized approval of high-value transactions.
Biometric Authentication
Biometric authentication uses unique biological characteristics, such as fingerprints or facial recognition, to verify a user's identity. This offers a high level of security and convenience. However, it's important to consider the privacy implications and ensure that biometric data is stored securely.
Common Mistake: Storing biometric data in an unencrypted format. This can expose sensitive information in the event of a data breach.
Example: Users can use their fingerprint to approve purchase orders on their mobile devices, eliminating the need to enter passwords.
2. Encrypting Data in Transit and at Rest
Encryption protects sensitive data by converting it into an unreadable format. This ensures that even if data is intercepted or accessed by unauthorised individuals, it cannot be understood.
Data in Transit
Data in transit refers to data being transmitted between systems or devices. It is crucial to encrypt data in transit to prevent eavesdropping and data interception. Use secure protocols such as HTTPS (TLS/SSL) for all communication between the user's browser and the approval system. Learn more about Approvals and our commitment to data security.
Common Mistake: Using unencrypted protocols such as HTTP for transmitting sensitive data. This leaves data vulnerable to interception by malicious actors.
Example: All communication between a user approving a document and the server hosting the approval system is encrypted using HTTPS, preventing eavesdropping during transmission.
Data at Rest
Data at rest refers to data stored on servers, databases, or other storage media. Encrypting data at rest protects it from unauthorised access in the event of a data breach or physical theft of storage devices. Use strong encryption algorithms such as AES-256 to encrypt sensitive data.
Common Mistake: Storing sensitive data in an unencrypted format on servers or databases. This makes it easy for attackers to access and steal data if they gain access to the system.
Example: All sensitive data stored in the approval system's database, such as invoice details and approval history, is encrypted using AES-256 encryption.
3. Regularly Auditing Access Controls
Regularly auditing access controls ensures that users have the appropriate level of access to the approval system and that any unauthorized access attempts are detected. Access control audits should be performed at least annually, or more frequently if there are significant changes to the organisation's structure or systems.
Reviewing User Permissions
Periodically review user permissions to ensure that they are still appropriate for their current roles. Remove access for users who have left the organisation or changed roles. Ensure that the principle of least privilege is being followed.
Common Mistake: Failing to review user permissions regularly. This can lead to users retaining access to data and functions they no longer need, increasing the risk of data breaches.
Example: A quarterly review of user permissions identifies several employees who have left the company but still have active accounts in the approval system. These accounts are immediately disabled.
Monitoring Audit Logs
Enable and monitor audit logs to track user activity within the approval system. Audit logs can provide valuable insights into potential security breaches or unauthorised access attempts. Regularly review audit logs for suspicious activity.
Common Mistake: Disabling or ignoring audit logs. This makes it difficult to detect and investigate security incidents.
Example: Audit logs reveal that a user has repeatedly attempted to access data outside of their authorised scope. This triggers an investigation to determine the cause of the suspicious activity.
Penetration Testing
Conduct regular penetration testing to identify vulnerabilities in the approval system's security. Penetration testing simulates real-world attacks to identify weaknesses that could be exploited by malicious actors. Consider engaging a reputable security firm to conduct penetration testing.
Common Mistake: Neglecting penetration testing. This leaves the approval system vulnerable to known and unknown security threats.
4. Training Employees on Security Awareness
Employees are often the weakest link in the security chain. Training employees on security awareness is crucial to prevent phishing attacks, social engineering, and other security threats. Training should cover topics such as password security, phishing awareness, data handling, and incident reporting. Frequently asked questions can also help reinforce security best practices.
Phishing Awareness
Train employees to recognise and avoid phishing emails and other social engineering attacks. Teach them to verify the sender's identity before clicking on links or opening attachments. Emphasise the importance of not sharing sensitive information via email or phone.
Common Mistake: Employees clicking on phishing links or opening malicious attachments. This can lead to malware infections or the compromise of sensitive data.
Example: An employee receives an email claiming to be from the IT department, requesting their password. The employee, having been trained on phishing awareness, recognises the email as suspicious and reports it to the IT department.
Password Security
Educate employees on the importance of using strong, unique passwords and avoiding password reuse. Encourage them to use password managers to generate and store passwords securely. Enforce password complexity requirements and regular password changes.
Common Mistake: Employees using weak or easily guessable passwords. This makes it easy for attackers to compromise their accounts.
Example: The organisation implements a policy requiring all employees to use passwords that are at least 12 characters long, contain a mix of uppercase and lowercase letters, numbers, and symbols, and are changed every 90 days.
Data Handling
Train employees on proper data handling procedures, including how to store, transmit, and dispose of sensitive data securely. Emphasise the importance of following data security policies and procedures.
Common Mistake: Employees storing sensitive data on unsecured devices or sharing it via unencrypted channels. This can lead to data breaches and compliance violations.
5. Incident Response Planning
Even with the best security measures in place, security incidents can still occur. Having a well-defined incident response plan is crucial to minimise the impact of a security breach and restore normal operations quickly. The incident response plan should outline the steps to be taken in the event of a security incident, including identifying, containing, eradicating, and recovering from the incident.
Incident Identification
Establish procedures for identifying and reporting security incidents. Encourage employees to report any suspicious activity or potential security breaches immediately. Implement monitoring tools to detect security incidents automatically.
Common Mistake: Failing to identify security incidents promptly. This can allow attackers to cause more damage and compromise more data.
Incident Containment
Take immediate steps to contain the security incident and prevent it from spreading to other systems or data. This may involve isolating affected systems, disabling compromised accounts, and blocking malicious traffic.
Common Mistake: Failing to contain security incidents effectively. This can allow attackers to escalate their attacks and compromise more systems and data.
Incident Eradication and Recovery
Eradicate the root cause of the security incident and restore affected systems and data to a secure state. This may involve removing malware, patching vulnerabilities, and restoring data from backups.
Common Mistake: Failing to eradicate the root cause of security incidents. This can lead to recurring incidents and further damage.
