2 Major Systems that can Surmount Cybersecurity Issues

By Enterprise Security Magazine | Monday, December 30, 2019

There are myriads of organizations and online brands, whose networks are vulnerable to unwanted intrusion and attacks. In this scenario, what organizations should do?

FREMONT, CA: Network intrusion has always been a big concern for industries. These unauthorized activities often jeopardize networks and their data security. Nowadays, hackers target online brands and companies for their attacks. To deal with it, an organization must possess a robust cybersecurity team to have a comprehensive understanding of the working of intrusions and effect formidable detection and prevention systems.

With the increasing activities such as resume services taking place on digital networks, identifying irregularities that can indicate an intrusion's occurrence has become increasingly complicated and challenging.

Intrusion Detection System (IDS)

An Intrusion Detection System (IDS) does the job of network surveying for malicious activities and issues warnings if any suspicious activity takes place. The threat is often reported to the administrator.

Apart from monitoring networks for potentially suspicious or malicious activity, IDS also look out for false alarms. Organizations need to appropriately set up IDS to identify what normal traffic on the network looks like in comparison to malicious activity. The following are two kinds of Intrusion Detection System.

1. Network Intrusion Detection System (NIDS)

NIDS is set up at a strategic point within the network for examining traffic from all the gadgets on the network. It mainly analyzes passing traffic on the complete subnet and compares the traffic passed on the subnet to the known attacks collection. After identifying an attack or sensing abnormal behavior, it sends an alert to the administrator.

2. Host Intrusion Detection System (HIDS)

HIDS operates on self-standing hosts or devices on the network. In a nutshell, it takes an existing system files' snapshot and compares it with the previous snapshots. Similarly, the system sends a warning to the administrator for investigation if the analytical systems files are found to be altered or deleted.

The detection techniques of IDS include signature-based technique and anomaly-based technique.

 Intrusion Prevention System (IPS)

IPS supervises network or system activities for malicious activities. The primary functions of the system are to detect malicious activity, allocate information about the activity, report it, and try blocking it.

IPS is considered as a supplement to IDS as both the systems monitor network traffic and system activities for malicious activity. The detection methods of IPS include signature-based detection, statically anomaly-based detection, and stateful protocol analysis detection.

The bottom line is that enterprises need to hire cybersecurity professionals as soon as possible to surmount these problems and deliver a hassle-free network.
