What is Logging and Monitoring in Cyber Security - Important or Not

Table of Contents [show]

When you're choosing cybersecurity software, what qualities are most important to you? Should it be agile, durable, or intelligent? These are all crucial aspects to consider. However, cybersecurity is about more than just spotting and stopping threats. Your security setup should do more than act like a bouncer, kicking threats out and leaving it at that. It needs to include security logging and monitoring, which are vital parts of keeping your cybersecurity strong.

Understanding Logging and Monitoring in Cyber Security

Security event monitoring and logging are the two sides of the same coin, and they're essential for keeping your digital world safe. Moreover, every action in your tech world, like sending emails, logging into systems, or updating firewalls, is a security event. These events should all “record” or "log" to observe what's happening in your digital space.

Now, monitoring those logs is where the prominent part happens. Organizations check these electronic logs for any signs of unauthorized activities. If they spot anything fishy or attempts by unauthorized people to access sensitive info, they take action. As a result, it moves the data to a safe place for further checking and deciding what steps to take next.

In today's world, where cyber threats are always lurking, the information we get from these logs is crucial. It helps us stay quick and responsive in protecting our digital stuff from bad actors. In short, logging is keeping a record of everything happening. On the other hand, monitoring watches those records for suspicious behavior. Together, they make sure your digital space stays safe and secure.

Working of Monitoring and Logging Technique

Making sense of security event logging and monitoring can be tricky, but it's crucial for keeping your digital space safe. 
 

• Collecting and Analyzing Data: Sometimes, your security logs have a massive pile of information. There's so much data that it's nearly impossible for a person to spot all the potential threats just by looking at it.
• Weeding Out the Noise: To make sense of this data overload, we need tools to sift through the logs and focus on the important stuff. We're looking for events that could harm the security or availability of sensitive information, like attempts by bad actors to sneak into your systems.
• Identifying Critical Events: Effective logging and monitoring mean keeping an eye out for specific types of events:
   
  • Reconnaissance: When hackers are snooping around, trying to learn about your digital setup.
  • Weaponization: When they start using what they've learned to attack your network. 
  • Delivery: The moment they launch an attack against vulnerabilities in your systems. 
  • Installing Malware: When they sneak in harmful software to stay hidden and keep causing trouble.
  • Command and Control: When they gain control of parts of your systems.
  • Taking Action: Figuring out what the hackers are up to and stopping them in their tracks.
     

• Long-Term Monitoring: This isn't just a one-time thing. We need to keep watching over time to spot any patterns or trends that could indicate ongoing threats. Any suspicious activity needs to be reported immediately so that action can be taken, and it is stored away for future analysis.

In simpler terms, security logging and monitoring are like having a team of detectives constantly scanning a massive library of information. Now, we’ll describe the objective of this cyber security monitoring and logging guide. 

What is the Objective of Logging and Monitoring?

Logging: It keeps track of events, errors, and activities, providing a record of what's been going on.

Monitoring: Monitoring checks various things like performance metrics, availability, and any potential issues that could affect how your applications work.
 

• Better Understanding: Logging gives you the "why" behind what's happening. It looks at security camera footage to find what happened during an incident.
• Comprehensive View: Monitoring shows you the overall health of your system, like a security alarm alerting you to potential problems.
• If you’ve both logging and monitoring, it gives you a complete picture of your system's health and helps you understand any vulnerabilities or issues. This way, you can keep your applications running smoothly and ensure a good experience for users.

In other phrases, logging is like keeping a detailed diary, and monitoring is like having a watchful guardian for your system. Together, they help you keep everything running smoothly and quickly address any problems that pop up. Now, we will elaborate on the pros and cons of the same. 

Pros and Cons of Security Logging and Monitoring

The following section will discuss the merits and demerits of the cyber security monitoring and logging guide.

Benefits

• All-in-One Platform: Log monitoring brings all your system and app logs into one place, making life easier for developers. They can quickly see what's going on without juggling different systems, leading to faster responses.
• Security Alerts: It has a security guard that alerts you to suspicious activity, like breaches or unauthorized access attempts. As a result, it lets you respond swiftly and nip potential threats in the bud.
• Quick Detection and Response: Speed matters in both user satisfaction and security. Log monitoring helps catch and fix issues fast, reducing risks and keeping things running smoothly.
• Automation: Log monitoring tools can automate tasks like monitoring, alerting, and fixing problems. However, it saves time, especially when dealing with lots of log data, and tools like SOAR systems can handle even more tasks automatically.
• Versatile Logs: You can use the same logs for both keeping an eye on your systems and facing security issues. This streamlines processes and cuts down on the need for separate tools.
• Investigating Incidents: Log data is gold for figuring out what went wrong during security events. It gives you a clear picture of breaches, helping you learn and improve.
• Compliance and Auditing: Log monitoring ensures you meet all the rules and regulations, providing reports that show you're following security standards.

In other words, log monitoring makes life easier by bringing everything together. As a result, it keeps you safe from cyber threats and helps you stay on the right side of the law.

Challenges

Logging and monitoring are crucial for keeping systems secure, but it comes with its own set of challenges. Here are some challenges and how to tackle them:

• Alert Overload: Too many alerts can overwhelm security teams. Use savvy alerting techniques to focus on critical warnings and avoid getting bogged down by noise.
• Complexity: With new technologies come new log formats, making monitoring more complex. Invest in tools that can handle different log types easily.
• Cost Management: Log monitoring can be costly. Look for tools with scalable pricing and control over data processing to manage costs effectively.
• Data Retention: Compliance with data retention rules is challenging. Use automated strategies to manage data effectively while meeting regulatory standards.
• Decentralized Data: Centralize your data to reduce costs and streamline management.
• Integration and Standardization: Merge logs from different sources and standardize formats for easier analysis.
• Manual Approaches: Manual methods waste time and compromise security. Automate log monitoring to save time and reduce risks.
• Performance Impact: Monitoring can slow down systems. Choose efficient tools that balance thorough monitoring with performance.
• Data Privacy: Logs can contain sensitive data. Use data protection measures and anonymization techniques to protect privacy.

By addressing these challenges, companies can ensure effective log management, better security, and compliance without unnecessary complications.

Conclusion

In simple terms, logging and monitoring are the eyes and ears of cybersecurity. They help organizations see what's going on in their digital world and listen for any signs of trouble. By using logging to keep records of events and monitoring to spot issues as they happen, companies can strengthen their cybersecurity, keep their critical data safe, and protect from cyber threats.
