Introduction
The benefits of artificial intelligence (AI) are now broadly acknowledged as a result of the increasing complexity of contemporary informationsystemsandtheresultingeverincreasingvolumeofbigdata. Particularly with the emergence of deep learning, machine learning (ML) technologies are already being used to addressvariousreal-worldissues.
Additionally, ML is correctly regarded as a technology enabler due to the significant potential it hasdemonstratedwhenusedtoautonomousvehiclesortelecommunicationnetworks(Zhang etal.,2022).
MachineLearning,isakeytechnologyforbothpresentandfutureinformationsystems,anditis already used in many different fields. There is a huge gap between research and practise, but the application of ML in cyber security is still in its infancy. As a result of the current state of the art, which prevents recognising the function of ML in cyber security, this disagreement has its origins there. Unless its benefits and drawbacks are recognised by a large audience, ML's full potentialwillneverberealised.

The latter call for developing a concept of "normality" and seek to identify events deviating from it under the presumption that such deviations correlate to security incidents. These two methods of detection work in conjunction with one another: misuse-based approaches are very accurate but can only identify known threats; anomaly-based approaches tend to raise more false alarmsbutaremoreeffectiveagainstnewattacks(Elsisietal.,2021).

The former can serve as full detection systems but calls for labelled data that was developed under some degree of human oversight.

The ability to use supervised or unsupervised ML algorithms is the distinctive feature of ML applications for cyber risk detection (schematically represented inFig.1).

MachineLearningin MalwareDetection Oneofthemostrecognisabledifficultiesincybersecurityis the struggle against malware. Since malware only affects onetypeofdevice,itcanonlybefoundbyexamining data atthehostlevel,orthroughHIDS. Antivirus software can be viewed as a subset of HIDS, in fact.

We specifically differentiate between two different uses of ML to detect phishing attempts: detection of phishing sites, where the aim is to identify web pages that are disguised to look like a legitimate website; and identification of phishing emails, which either point to a vulnerable website or stimulate a response that includes sensitive information (Geetha & Thilagam,2021).
One of the most frequent ways to infiltrate a target network is by phishing, which is still a seriousdangertoonlinesecurity.Modernenterprisesmustprioritisetheearlyidentificationof phishingefforts,whichcanbetremendouslyhelpedbyML.

To establish the groundwork for a greater deployment of ML solutions to safeguard present and future systems, this log aims to stimulate significant improvements of machinelearning (ML) in the fieldofcybersecurity.
Defensive mechanisms need to have the ability to quickly adapt to the changing settings and dynamic threat landscape in order to prevent such incidents and reduce the myriad hazards that canaffectexistingandfutureITsystems.
