With the increased use of the internet, threats to privacy and security remain on the top. Companies are investing hugely to get rid of those threats and save themselves from vulnerabilities. A network intrusion might be a new term for many internet users, but this has to be taken into consideration before anyone breaks into your network.
What is Network Intrusion?
A network intrusion denoted to any unauthorized or aggressive activity on a digital network. Unauthorized activities can lead to the risk of the security of networks and data. In today’s digital world, small and big enterprises are subject to these attacks. These organizations invest heavily in securing their networks and hire personnel to deal with any type of vulnerabilities.
With the number of activities taking place simultaneously on the same network, it is quite impossible to identify the irregularities and occurrence of intrusion. In this post, we are going to discuss some of the ways to detect network intrusion and measures to prevent it. Let’s get started.
Signature-Based Method
The signature-based method denotes to finding of attacks based on a set of defined criteria including identified malicious instruction sequences and network traffic common to malware. The identified patterns are called signatures. Signature-based Intrusion Detection System (IDS) can seamlessly detect existing or known attack patterns. However, it is hard to detect new attacks without existing patterns.
Anomaly-Based Method
Anomaly-based IDS was mainly introduced to detect unidentified malware attackers, which took place due to the rapid development of new malware. The purpose is to use machine learning to develop a trustworthy activity model and relate it to new behavior that is going against the model. It is then professed as suspicious or potentially malicious, if not present in the model.
The anomaly-based method is much better than the signature-based IDS model. The reason is that the models can be molded according to the given hardware configuration. While the method helps to detect the former unidentified attacks, it is vulnerable to false positives that are formerly unknown.
Intrusion Prevention System (IPS)
Intrusion Prevention Systems includes network security devices that detect network and system activities for any potential malicious attack. Generally, the core function of the Intrusion Prevention System is to detect malicious activity, collect information, report it, and block it.
The IPS are considered as an alternative to IDS because of both IPS and IDS screen system activities and network traffic for malicious activity. However, IPS takes a more practical and proactive approach such as resetting a connection, blocking traffic from the unreceptive IP address, and sending an alarm.
