In today's digital world, organizations face a growing number of security threats, including cyber-attacks, data breaches, and insider threats. To ensure the safety of their systems, data, and customers, organizations must implement a robust security monitoring and logging program. 

If security logging and monitoring mechanisms are not properly implemented or maintained, they can be rendered ineffective, leaving organizations vulnerable to cyber threats. In this blog, we will explore the risks associated with security logging and monitoring failures and best practices to avoid them. But before we get to that, let’s understand what security logging and monitoring are and their importance. 

What is security logging and monitoring?

Security logging and monitoring involves the collection and analysis of data from an organization's network and computer systems to identify potential security threats and incidents. The collected data is typically analyzed using security information and event management (SIEM) software (ex: IBM QRadar, Splunk, SolarWinds Security Event Manager) but you can extend this to advanced systems such as an AI engine (ex: LogRhythm’s AI Engine).

This practice enables organizations to detect and respond to security incidents in a timely and efficient manner as it provides an early warning system for potential security breaches. By analyzing the data, you can identify potential threats by looking for patterns or anomalies, investigate them further, and take appropriate action to mitigate the risks. If a potential security incident is identified, alerts can be sent to IT teams or security professionals, who can investigate further and take appropriate action.

Why do you need security monitoring and logging?

Security monitoring and logging are critical components of an organization's security program. Here are some reasons why security monitoring and logging are crucial:

Early detection of security threats

The primary goal of security monitoring and logging is to identify security threats early so that you can address them before they cause significant damage. Without proper monitoring and logging, it may take days, weeks, or even months before an organization realizes that a security breach has occurred. By that time, the damage may be severe, and the cost of recovery could be substantial.

Security monitoring and logging enable organizations to detect security threats in real-time or near real-time, allowing them to respond quickly and minimize the damage.

Incident response

Security monitoring and logging can play a critical role in incident response. When a security breach occurs, you need to know what happened, when it happened, and what systems and data were affected. By analyzing security logs, organizations can identify the cause of the breach and take appropriate measures to contain it. Security logs can also be used to trace the activities of the attacker and provide valuable information for law enforcement and legal proceedings.

Threat intelligence

Security monitoring and logging can provide valuable insights into the types of threats that an organization faces. By analyzing security logs, organizations can identify patterns and trends in attack behavior and develop effective security strategies.

For example, if an organization notices a significant increase in phishing attacks targeting its employees, it can develop a training program or can hire a 3rd party security company to educate its employees on how to identify and avoid these types of attacks.

Compliance requirements

Many regulatory frameworks require organizations to implement a security monitoring and logging program. For example, the Payment Card Industry Data Security Standard (PCI DSS) mandates that organizations that process credit card transactions maintain logs of all system activity and monitor those logs for suspicious behavior.

In addition, regulations such as the General Data Protection Regulation (GDPR) require organizations to ensure the security of their customer's personal information. By implementing a robust security monitoring and logging program, organizations can demonstrate compliance with these regulations.

Now that we’ve understood how crucial security logging and monitoring are and how they can benefit an organization, let’s discuss what might happen if it is not done right.

What are the risks of improper security logging and monitoring?

While security monitoring and logging can provide significant benefits to an organization, improper implementation or neglect can lead to severe risks and consequences. If an organization fails to log all the necessary data or configures the logging process incorrectly, it may miss critical information about security threats. Let’s look into some common risks of improper security logging and monitoring.

Lack of audit trail

If a system does not maintain any logging mechanism or these mechanisms fail, there is no audit trail for events and security analysis. For example, if logs are locally stored and if the server fails, these logs become unavailable. Attackers can continue to damage the system because their identity and method of attacking cannot be easily determined. Without proper logging and monitoring, it becomes challenging to identify security incidents and respond quickly to mitigate them.

Insufficient logging

One of the most common security logging and monitoring failures is insufficient logging. It is crucial to log all important transactions, such as login attempts, user/pass, and other critical transactions. Without enough logging, it can be challenging to form a picture of the security incidents and identify potential threats.

Weak monitoring systems and false positives

Weak monitoring systems may not be able to detect suspicious or alarming future situations. They can miss potential threats and leave the organization vulnerable to attack.

On the other hand, these systems can generate an alert for an activity that is not actually a security threat. If there are too many false positives, it can lead to alert fatigue, where security professionals become desensitized to alerts and may miss real security threats.

Lack of integrity

If monitoring and logging are not protected for integrity, anyone can corrupt the data to give a false alarm, making it difficult to identify actual security threats.

Compliance violations

As mentioned earlier, many regulatory frameworks require organizations to implement a security monitoring and logging program. If an organization fails to comply with these regulations, it may face legal and financial consequences, such as fines or legal action.

Overwhelming data volume

If an organization logs too much data or fails to manage the logs properly, it can quickly become overwhelmed with the sheer volume of data. This can make it difficult to identify and respond to actual security threats promptly. 

Loss of reputation

A security breach can have a severe impact on an organization's reputation. If an organization fails to detect or respond to a security breach quickly, it may lose the trust of its customers and partners. 

Security logging and monitoring failures can have significant impacts on an organization's ability to detect, respond to, and recover from security incidents. Understanding the risks of security logging and monitoring failures is crucial for developing effective strategies. To help you build such strategies, let’s look into some best practices. 

Best practices to avoid security logging and monitoring failures

Develop a comprehensive logging and monitoring plan

Develop a comprehensive logging and monitoring plan that covers all critical components and systems in the organization. The plan should specify what data should be logged, how it should be stored, and how long it should be retained.

For example, make sure that every user login attempt and failed login attempt is logged properly. This will help you identify any unauthorized access attempts.

Ensure the system is configured correctly

Ensure that the logging and monitoring system is configured correctly and that it captures all the necessary information. System administrators should review the configuration regularly to ensure that it is up-to-date and effective.

Manage and monitor log data

The logs should be kept in a formatted manner that can be easily used by other functions and log management solutions. Unformatted logs can be difficult to parse and analyze, so it's important to ensure that they are structured and easy to read. Manage logs such that they can be easily accessed and used.

Monitor log data regularly to identify and respond to potential security incidents. Use log analysis tools to help identify patterns and anomalies that may indicate a security breach. Ensure that the system alerts in real-time. Alerting after the damage has been done is not beneficial.

Ensure data integrity

Protect the integrity of the logging and monitoring data to prevent tampering and corruption. Store log data in a secure location and encrypt it in transit and at rest. Keeping a backup of logs helps you quickly recover from issues like system crashes or hardware failures. Back up logs and sync them to another server. This provides redundancy and ensures that you have a backup of your logs in case of a disaster.

Develop a data retention policy

Develop a data retention policy that specifies how long log data should be retained. Ensure that the retention policy meets regulatory requirements and industry best practices such as HIPAA and PCI DSS.

Provide adequate resources

Provide adequate resources, including staff and technology, to manage and maintain the logging and monitoring system effectively. Ensure that staff is trained on the logging and monitoring system and understands how to identify and respond to potential security incidents.

Regularly test the logging and monitoring system

Regularly test the logging and monitoring system to ensure that it is functioning correctly. Conduct penetration tests to identify potential vulnerabilities and test the system's effectiveness in detecting and responding to security incidents. By identifying insufficient logging and monitoring, components with known vulnerabilities, and injection risk, you can take action to strengthen your network and application security. 


Effective security logging and monitoring are critical to safeguarding organizations against cyber threats and data breaches. As we have discussed in this blog, the risks of security logging and monitoring failures can be severe, including the inability to identify and respond to security incidents and breaches.

By following best practices and implementing robust security logging and monitoring mechanisms, organizations can significantly reduce the risk of security breaches and other cyber threats. By regularly testing and updating their logging and monitoring systems, organizations can ensure their security mechanisms are effective and up to date. Failing to do so might result in hefty fines, loss of business, and additional costs of dealing with a breach. Ultimately, by prioritizing security logging and monitoring, organizations can better protect their systems and data from potential attacks and safeguard their reputation and customer trust.
