### Cluster#3 Intrusion Detection System
#### 3.3.2 Citation Bursts  
CiteSpace is capable of identifying bursts of frequent citations within a specific period and assigning burst value to the corresponding literature. A higher burst value indicates a higher citation frequency for that literature. By synthesizing the literature information, such as the title, authors, time of publication, time of burst, and burst duration, researchers can gain insights into the research focus or hotspot at different stages. The results show that the top five bursts are [PERSON] (2014) [9], [PERSON] (2012) [12], [PERSON] (2011) [55], [PERSON] (2011) [56], and [PERSON] (2014) [10], which are all original research papers (Table 7 and Figure 11).
