Britannica describes artificial intelligence as the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings. The trouble in this definition is the term intelligent. How do you define intelligence? How do you measure intelligence? You can say something is intelligent if it can do descriptive, diagnostic, predictive, and prescriptive analytics at the same time or within a short timeframe.

Deep learning is performed through Artificial Neural Networks (ANNs), which are designed to mimic the functionality and connections of neurons seen in the human brain. FREMONT, CA: Almost every business is undergoing a revolution due to artificial intelligence (AI). Deep Learning (DL), an AL methodology, is propelling the high-tech industry forward with an almost infinite index of applications ranging from object recognition for autonomous vehicle systems to potentially saving lives by assisting doctors in more accurately detecting and diagnosing cancer. The most prevalent risks and cyberattacks that cybersecurity teams encounter are listed below; now, it's time to discuss how deep learning technologies might help. Traditionally used malware detection methods, such as standard firewalls, rely on a signature-based detection approach. The company maintains a database of known risks, which it often updates to include newly discovered dangers.

The goal of any business is to improve productivity, enhance the customer experience, and maximise profits--Artificial Intelligence (AI) can play a crucial role on all these fronts, says Ramprakash Ramamoorthy, director of research at ManageEngine, the enterprise IT management division of Chennai-based business software maker Zoho. "The enormous growth witnessed in cloud computing has resulted in a huge amount of generated data. This is where AI steps in. Utilising AI to analyse vast amounts of collected data helps businesses gain a deep understanding of their systems," he says. Ramamoorthy stresses that when deployed correctly, AI systems can predict outages, help provide proactive infrastructure management and ensure better service availability.

Some attacks may still slip "under the radar" though, which is why tools that leverage machine-learning, like User and Entity Behavior Analytics (UEBA), are an important support to your SIEM as they will detect more unusual threats as well as greatly increase the overall fidelity of your security alerts. SIEM and UEBA are further supported by threat hunting tools that enable your hunt teams to track down any other threats that may still be lurking in your system. All three approaches are important to your threat detection and response ecosystem.

There are many SIEM solutions available. Some of those ML/AI tools available are using pure statistics for outlier detection apart from current hot topic ML, AI algorithms. What is tactical SIEM? if you are spending 80 percent of your time within a SIEM tool doing alert review and analysis, then you are on the right track. If you are an organization that is instead focusing heavily on collecting more data sources, applying patches, or running compliance reports, then your SIEM implementation may not be tactical. So correlation/alert is the heart of SIEM.

You can certainly write rules with machine learning models. That is one approach: to create a machine learning model that is a rule or a set of rules.

The analysis of the behaviour of individuals and entities (UEBA) is an area of artificial intelligence that detects hostile actions (e.g. attacks, fraud, influence, poisoning) due to the unusual nature of observed events, by affixing to a signature-based operation. A UEBA process usually involves two phases, learning and inference. Intrusion detection systems (IDS) available still suffer from bias, including over-simplification of problems, underexploitation of the AI potential, insufficient consideration of the temporality of events, and perfectible management of the memory cycle of behaviours. In addition, while an alert generated by a signature-based IDS can refer to the signature on which the detection is based, the IDS in the UEBA domain produce results, often associated with a score, whose explainable character is less obvious. Our unsupervised approach is to enrich this process by adding a third phase to correlate events (incongruities, weak signals) that are presumed to be linked together, with the benefit of a reduction of false positives and negatives. We also seek to avoid a so-called "boiled frog" bias inherent in continuous learning. Our first results are interesting and have an explainable character, both on synthetic and real data.

Let's start by dispelling the most common misconception: There is very little if any true artificial intelligence (AI) being incorporated within enterprise security software. The fact that the term comes up frequently is largely to do with marketing, and very little to do with the technology. Pure AI is about reproducing cognitive abilities. That said, machine learning (ML), one of many subsets of artificial intelligence, is being baked into some security software. But even the term machine learning may be employed somewhat optimistically.

Since then, big data security analytics sort of morphed into machine learning, which led to the creation of a new security technology category, user and entity behavior analytics (UEBA). UEBA was designed to monitor user behaviors like logins, remote access, network connections, etc., model "normal" behavior, and then detect anomalies that may indicate an attack in progress. UEBA proponents claimed that based upon this new capacity, new machine learning-based technology was destined to become a huge market as it replaced SIEM as the system of record for security analytics and operations.

Around 2010, security analytics technologies started to integrate big data science and open-source technologies like Hadoop (and HDFS), Pig, Mahout, etc. The goal? Ingest, process, and apply new types of algorithms to security data to supplement human intelligence for finding needles in growing haystacks of security data. The U.S. Department of Energy was an early pioneer in this area with a project called Orca from the Oak Ridge National Lab.
