Security is one of the biggest concerns today. Ever since the advent of the 21st century, the world has been facing several challenges regarding the security of people, economy, and infrastructure. One of the facets of the security concern in this new millennium, the digital age, is information security, often known as cybersecurity. The complexities of the physical security space have multiplied in the cyberspace due to sophisticated threat mechanisms and the ever evolving technological advances. Traditional crimes are now being vectored through cyberspace, ranging from public attacks, financial fraud, intellectual property violations, sabotage of critical infrastructure, compromise of security intelligence information, and even penetration into national defence communications. All of these bear significant human and economic consequences. As information technology is being integrated into the physical world increasingly, the risks of these consequences escalate every day.
Cyberspace is more difficult to secure than the physical world. The ability of malicious activities to originate from anywhere in the world, the integration of physical systems with cyberspace, and the possibility of new vulnerabilities arising in complex cyber networks are the key factors for this difficulty. Because of the scale of consequences possible in the cyberspace, Cybersecurity has now become an important mission for defence establishments, law enforcement agencies, and national security forces worldwide. This created a need to have special purpose technical teams within these agencies and forces to address the security concerns in the cyber arena. The range of operations of these teams varies: network security & defence, post-event forensics analysis, hacking & penetration, security intelligence & surveillance, and on-field threat defence, are the common domains.
In order to detect and counter security threats in the cyberspace, security teams need to be able to see beyond the usual level of network elements. They should have the ability to see through those elements and view the actual traffic running over the network. If they are able to analyse actual data packets flowing over the network, they can identify malicious data patterns and detect threats in real-time. To do that, a packet capture mechanism is required for intercepting and capturing packets from the live traffic.
