What is Network Forensics?<\/h2>\n<\/div>\n<\/div>\n
\n
\n

\n\t\t\t\t\u201cNetwork forensics is a science that centers on the discovery and retrieval of information surrounding a cybercrime within a networked environment. Common forensic activities include the capture, recording and analysis of events that occurred on a network in order to establish the source of cyberattacks.\u201d\t\t\t<\/p>\n

\n\t\t\t\t\t\t\t\t\t\t\tInfosec Institute\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n<\/div>\n<\/div>\n
\n
\n

This is one definition by <\/span>the Infosec<\/span> Institute but to explain it in simpler terms \u2013 Network Forensics is a process where we collect and analyze organizations\u2019 traffic data to detect any potential cyberattack or investigate any cybercrime. You can think of network forensics<\/span> analysis<\/span> as putting up CCTV cameras on your network so in case of any data breach you can look at recorded data and track the root cause.<\/span>\u00a0<\/span><\/span><\/p>\n<\/div>\n<\/div>\n

\n
\n

\n\t\t\t\tAccording to the 2023 Annual Data Breach Report, there was a staggering increase of 78 percent in data compromises as the number went from 1,801 in 2022 to 3,205 in 2023.\t\t\t<\/p>\n<\/div>\n<\/div>\n

\n
\n

The increase in <\/span>the number<\/span> of data compromises states that network forensics<\/a> is becoming vital for every organization. It can not only detect and prevent cybercrimes but also helps with ensuring compliance and collecting digital evidence.<\/span><\/span>\u00a0<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
