Malware Detection Module using Machine Learning Algorithms to Assist in Centralized Security in Enterprise Networks
Malicious software is abundant in a world of innumerable computer users, who
are constantly faced with these threats from various sources like the internet,
local networks and portable drives. Malware is potentially low to high risk and
can cause systems to function incorrectly, steal data and even crash. Malware
may be executable or system library files in the form of viruses, worms,
Trojans, all aimed at breaching the security of the system and compromising
user privacy. Typically, anti-virus software is based on a signature definition
system which keeps updating from the internet and thus keeping track of known
viruses. While this may be sufficient for home-users, a security risk from a
new virus could threaten an entire enterprise network. This paper proposes a
new and more sophisticated antivirus engine that can not only scan files, but
also build knowledge and detect files as potential viruses. This is done by
extracting system API calls made by various normal and harmful executable, and
using machine learning algorithms to classify and hence, rank files on a scale
of security risk. While such a system is processor heavy, it is very effective
when used centrally to protect an enterprise network which maybe more prone to
such threats.Comment: 6 page
Evolution and Detection of Polymorphic and Metamorphic Malwares: A Survey
Malwares are big threat to digital world and evolving with high complexity.
It can penetrate networks, steal confidential information from computers, bring
down servers and can cripple infrastructures etc. To combat the threat/attacks
from the malwares, anti- malwares have been developed. The existing
anti-malwares are mostly based on the assumption that the malware structure
does not changes appreciably. But the recent advancement in second generation
malwares can create variants and hence posed a challenge to anti-malwares
developers. To combat the threat/attacks from the second generation malwares
with low false alarm we present our survey on malwares and its detection
techniques.Comment: 5 Page
Malware Detection Using Dynamic Analysis
In this research, we explore the field of dynamic analysis which has shown promis- ing results in the field of malware detection. Here, we extract dynamic software birth- marks during malware execution and apply machine learning based detection tech- niques to the resulting feature set. Specifically, we consider Hidden Markov Models and Profile Hidden Markov Models. To determine the effectiveness of this dynamic analysis approach, we compare our detection results to the results obtained by using static analysis. We show that in some cases, significantly stronger results can be obtained using our dynamic approach
