SIEM Tools Another defense measure against zero-day threats is utilizing Security Information and Event Management tools SIEM detection: New attack vectors and vulnerabilities are discovered every day. As previously discussed firewalls, IDS and Intrusion Protection Systems (IPS) hunt for malicious activity at various points across the network from the perimeter to endpoints. Taking the search to another level, a SIEM solution has the capability to detect zero-day attacks. This capability can detect activity associated with an attack rather than the attack itself such as a well-crafted spear-phishing attack using a zero-day exploit has a high likelihood of making it through spam filters, firewalls and antivirus software, and being opened†¦show more content†¦After the bug is made known publicly, the exploit raises five times the magnitude† ([ANU], 2013). By utilizing algorithms from data-mining, identifies the frequency of the exploit and can add a rating of the potential of th e threat impacting new versions of software enhancing a defense strategy. Studies show that threats can be identified with a 98.5% accuracy with 2.5% false positive rate. Understanding the delta between accepted and behavior mimicking a compromising behavior better equips professionals awareness of a threat or exploit. Data Analytics Solution Using big data analytics brings the capability of delivering vital information for detecting the formation of an attack prior to it striking and penetrating network defenses. By identifying and containing the exfiltration of data by malicious insiders, an organization can build a stronger cyber defense posture. Possessing the knowledge of the differences between acceptable and nefarious behavior is the key to identifying and stopping zero-day exploits. Big data analytics expands the knowledge base for anomaly detections by applying innovative pattern recognition techniques with machine learning algorithms identifying malicious behavior. Using big data analysis, the capability of predictive analytics through machine learning to recognize patterns in open-source data, supports
