An essential part of network security is knowing what the characteristics of an attack are, so they can be countered or prevented. When the university suffered an overwhelming internal DDoS attack, it required administrators to reevaluate its security guidelines based on what was known about the attack.…

The signature based technique is easier for deployment, since it does not need to learn the environment[5]. It is very effective against known attacks, but it cannot detect new intrusions until it is updated with the new signatures on its database.Therefore, they are easy to evade and can be easily bypassed by intruders by modifying known attack signatures and also target systems, that are not updated with new signatures that detect the modification. The architecture shown in Fig.1, uses the preprocessing to evaluate the signature and compare those signatures to the known signatures in the database. If there is a match then alert is issued, else the detection system does…

A cyber-attack is a deliberate exploitation of computer systems, technology-dependent enterprises, and networks (Janssen, n.d.). There are 11 potential security threats thought to be the top security threats for 2013; targeted attacks and cyber-espionage, hacktivism, nation-state-sponsored cyber-attacks, legal surveillance tools, clouds and malware, privacy threats, fake security certificates, ransomeware spreading globally, MAC OS malware, mobile malware, and vulnerabilities and exploits (Davis, 2013). Symantec’s 2013 Internet Security Threat report finds that there was a 42% increase in targeted attacks in 2012…

Organizations invest a large portion of their information technology budgets on security applications and services, such as antivirus software, firewalls, and encryption. But no matter how much security hardware or software you deploy, how tightly you control the rights of users, or carefully you configure security permissions on your data, you should not consider the job complete unless you have a well-defined, timely auditing strategy to track the effectiveness of your defenses and identify attempts to circumvent them.…

The Internet is growing fast and doubling its number of websites every 53 days and the number of people using the internet is also growing. Hence, global communication is getting more important every day. At the same time, computer crimes are also increasing. Countermeasures are developed to detect or prevent attacks - most of these measures are based on known facts, known attack patterns. Countermeasures such as firewalls and network intrusion detection systems are based on prevention, detection and reaction mechanism; but is there enough information about the enemy?…
Definition: “A security resource who's value lies in being probed, attacked or compromised” Doesn’t have to be a system: Honeytokens We want to get compromised! Certainly not a standalone security mechanism. Why? • FUN! • No false-positives! • Research: Malware analysis/reverse engineering • Reducing available attack surface/early warning system…
Computer and network security present great challenges to our evolving information society and economy. The variety and complexity of cybersecurity attacks that have been developed parallel the variety and complexity of the information technologies that have been deployed, with no end in sight for either. In this paper, we delineate between two classes of information systems attacks: autonomous attacks and cognitive attacks.…
