Detecting unusual network activity


: Detection of Unusual Network Activity


– Network Security is a major concern for organizations and individuals alike, with the increasing number of cyber threats, it has become necessary to detect any unusual network activity.
– This article aims to provide an in-depth solution to detecting unusual network activity by highlighting some of the most effective methods and tools used in network security monitoring.
– Definition of Unusual Network Activity
– Unusual network activity refers to any deviation from normal patterns of network behavior. It could be a sudden spike in traffic, unexpected connections, or access to restricted resources.
– Methods for Detecting Unusual Network Activity
– 1. Baselining
– Baselining is the process of establishing a baseline of normal network activity by monitoring network traffic over an extended period. This helps to identify any deviation from normal behavior.
– Tools used in baselining include Snort, Wireshark, and SolarWinds Network Performance Monitor.
– 2. Behavioral Analysis
– Behavioral analysis involves the use of machine learning algorithms to detect anomalous behavior on the network. This method analyzes patterns and identifies any deviations from normal behavior.
– Tools used in behavioral analysis include Splunk, IBM QRadar, and LogRhythm.
– 3. Traffic Analysis
– Traffic analysis involves monitoring network traffic to detect any unusual activity such as unexpected connections or data transfer. This method can be used to identify malicious activities on the network.
– Tools used in traffic analysis include Cisco Stealthwatch, Darktrace, and Bro IDS.
– Best Practices for Detecting Unusual Network Activity
– 1. Use multiple detection methods
– Using multiple methods of detection increases the chances of identifying unusual activity on the network.
– 2. Implement real-time monitoring
– Real-time monitoring enables quick response to any unusual activity, reducing the impact of a potential breach.
– 3. Regularly update detection tools
– Detection tools need to be updated regularly to ensure they can detect the latest threats and vulnerabilities.


– Detecting unusual network activity is critical in preventing cyber attacks. By using multiple methods of detection, real-time monitoring, and regularly updating detection tools, organizations can effectively monitor their networks for any unusual activity.
