Real-time monitoring to detect suspicious activity

Information security is a critical priority for any organisation that uses document management platforms. As the digitalisation of business processes becomes increasingly common, the need to protect sensitive data against cyber threats is growing sharply. One of the most effective approaches to ensuring security is real-time monitoring. This approach enables suspicious activity to be detected immediately and preventive measures to be taken before any damage occurs.

Monitoring a document management platform in real time helps to protect data against unauthorised access. Furthermore, it makes it possible to identify anomalous behaviour that may indicate a potential security breach. This article presents the best practices, technologies and benefits associated with implementing real-time monitoring in document management platforms. Aimed at the managers of these platforms, it offers a comprehensive view of how to safeguard the integrity and confidentiality of business data.

 

Benefits of real-time monitoring

Real-time monitoring offers a wide range of benefits that go beyond simple threat detection. The main benefits include:

  • Early threat detection: the ability to identify suspicious activity as it happens allows organisations to react quickly, minimising the impact of any attempted security breach.

  • Improved compliance: many sectors are subject to strict data protection regulations. Real-time monitoring makes it easier to comply with these rules, because it provides detailed logs and reports that demonstrate the security measures in place.

  • Reduced operational risk: the ability to monitor and respond quickly to threats reduces the risk of operational disruption caused by security incidents.

  • Protection of sensitive data: by monitoring access to documents and their movement, organisations can ensure that only authorised users handle confidential data.

 

Technologies for real-time monitoring

An effective real-time monitoring strategy requires advanced technologies that automatically detect anomalies and generate instant alerts. Some of the most effective technologies include:

Intrusion detection and prevention systems (IDS/IPS)

Intrusion detection systems (IDS) and intrusion prevention systems (IPS) are crucial tools for real-time monitoring. While IDS analyse network traffic for suspicious activity, IPS not only detect but also automatically block such activity. These systems are therefore particularly effective at detecting unauthorised access attempts and blocking attacks before they can compromise the integrity of the platform.

Machine learning and artificial intelligence

Machine learning (ML) and artificial intelligence (AI) technologies have transformed real-time monitoring, because they make it possible to analyse large volumes of data continuously and identify patterns that indicate suspicious behaviour. For example, ML algorithms can be trained to recognise anomalous activity based on historical data. In addition, AI can automate incident response by prioritising threats according to their severity.

 

Implementing real-time monitoring

Implementing real-time monitoring on a document management platform should follow a set of steps that ensure the system is effective and efficient. The main steps include:

Defining security policies

Before implementing monitoring, it is essential to define clear policies that set out security rules and procedures. These policies should include guidelines on who can access certain documents, which actions are permitted and what automatic responses apply when suspicious activity is detected.

Configuring alerts and notifications

Configuring alerts and notifications is one of the most important steps in real-time monitoring. Alerts should immediately notify administrators of any activity that breaches established security policies. In addition, it is important to configure alerts in a way that minimises false positives, which can lead to “alert fatigue” and reduce the system’s effectiveness.

Employee training

Employees play a crucial role in platform security. It is essential that all users receive training on security policies and on how to respond to security incidents. This training should cover how to identify suspicious activity and the need to notify administrators immediately.

Integration with other security tools

To maximise the effectiveness of real-time monitoring, it is important to integrate the system with other security tools, such as firewalls, antivirus software and identity and access management (IAM) systems. This integration enables a more comprehensive and coordinated approach to security.

 

Challenges and solutions in real-time monitoring

Despite its many benefits, real-time monitoring also presents some challenges. One of the main challenges is the complexity of managing the large volumes of data generated by continuous monitoring. To deal with this challenge, it is essential to use big data technologies that can quickly process and analyse large amounts of information.

Another challenge is protecting user privacy while monitoring takes place. Monitoring policies must be aligned with data protection laws and regulations, so that users’ privacy is respected.

Finally, real-time monitoring requires significant computing resources, which can be a challenge for some organisations. However, the solution lies in cloud computing technologies, which offer scalability and allow resources to be allocated as needed.

 

What to monitor on a document management platform

Not all events are equally valuable. Monitoring should therefore focus on the signs that most often precede an incident:

  • multiple failed login attempts on the same account;
  • logins from unusual countries or networks;
  • mass document downloads within a short period;
  • permission changes or the creation of new administrators;
  • out-of-hours access to sensitive documents;
  • deletion of many documents at once.

In this way, each alert corresponds to a specific risk and the team avoids wasting time on unimportant events.

 

Monitoring and worker privacy

Access monitoring involves users’ personal data. It should therefore have a clear security purpose, be proportionate and be communicated to employees. In addition, logs should have restricted access and defined retention periods. This way, the organisation protects information without undermining workers’ rights and complies with the GDPR and employment law.

 

Practical example: An unusual document download

Suppose that, on a Friday night, an employee’s account starts downloading hundreds of contractor worker records. Real-time monitoring detects the unusual volume and generates an alert.

The security team immediately blocks the account and contacts the employee, who confirms they are not working. Next, the team finds that the password had been obtained through phishing. Finally, it assesses the documents accessed and decides whether the Portuguese data protection authority (CNPD) needs to be notified. As a result, the incident is contained in minutes rather than days.

 

Indicators for assessing monitoring

To know whether monitoring is working, it is worth tracking a few indicators. These include, for example, the average time between a suspicious event and its detection, the time to respond and the percentage of alerts that turn out to be false positives. Moreover, the number of incidents detected by the organisation itself, rather than by third parties, is a good sign of maturity. The team can thus adjust rules and priorities based on data.

 

Frequently asked questions

Does real-time monitoring require a team available 24 hours a day?

Not always. Many organisations combine automatic responses, such as blocking accounts, with external monitoring services outside working hours.

How long should access logs be kept?

For as long as necessary to investigate incidents and meet legal obligations, without exceeding what is proportionate. In general, the organisation should define this period in its security policy.

Do small businesses also need monitoring?

Yes, although on an appropriate scale. Simply enabling alerts for suspicious logins and unusual downloads already provides important protection with little effort.

 

Conclusion

Real-time monitoring of document management platforms is an essential practice for the early detection of suspicious activity and the protection of sensitive data. Implementing it effectively requires advanced technologies, clear policies and ongoing employee training.

In a business environment where information security is increasingly critical, real-time monitoring not only improves security but also supports regulatory compliance and protects the integrity of operations. In short, by adopting these practices, organisations can ensure that their document management systems remain secure and efficient, minimising risks and maximising trust in their digital infrastructure.
