A Short Note On The Security Attacks And Cyber Sensor...

TEODOR-GRIGORE LUPU presented the different types of attacks in wireless sensor networks. Attacks on the different layers are categorized. The security attacks and the threats can be categorized based on the mechanisms used in those attacks [4]. Traffic analysis is the process of analyzing the messages in order to identify the data from patterns in the connection. Data from an authentic person who is entering into a network can be fabricated by an attacker and it can be replayed the next day. Compromised nodes within a network can cause the internal attack and it is hard to identify those compromised nodes in the network. Thinking like an attacker is a better choice for creating the intrusion detection system. Ju young Kim et al presented a study of the different threats, attacks and vulnerabilities for Wireless Sensor Networks (WSNs). In node capture attack, an attacker gains complete gain over a node by physically accessing the node. Then the attacker can remove the cryptographic functions and get the access to the data stored on that captured node. The countermeasures for reducing the risk of eavesdropping on wireless transmissions are the use of encryption to preserve confidentiality and it should be more difficult to locate and intercept the wireless signals [5]. Hardware attestation, software authentication and validation are the countermeasures against the software attacks. The different classes of these threats are defined to identify a possible countermeasureShow MoreRelatedThe Importance of Corporate Network Security Essay2849 Words   |  12 Pagesthreats that can proof costly if not handled professionally. Good news is that there are measures that can be adopted to form a robu st computer network system that will ensure minimal or no intrusion by any assailants.

Training end users to identify attacks against them will reduce the attack surface of the organization. Training managers to be more aware of possible attacks against them will prevent the possible release of the highly sensitive information that their eyes are privy to.
