Intrusion Detection System in Reston

Intrusion Detection System (IDS) is a system that monitors network traffic for suspicious activity and alerts issues when such activity is detected. These are software applications that scan the network or system for malicious activity or policy violations. Any malicious activity or breach is usually reported to administrators or recorded centrally using the Security and Event Management Information System (SIEM). The SIEM system integrates output from multiple sources and uses warning filtering techniques to distinguish malicious activity from false positives Intrusion Detection System in Reston.

The intrusion detection system monitors the network for potentially dangerous activity, but is also exposed to false positives. Therefore, companies need to perfect their IDS products when they are first installed. This means that intrusion detection systems are set up properly to see how normal network traffic compares to malicious activity.

The intrusion prevention system also monitors network packets entering the system to check for associated malicious activity and immediately send alerts.

Intrusion detection system classification:
IDS is divided into 5 types:

Network Intrusion Detection System (NIDS):
A Network Intrusion Detection (NIDS) system is developed at a planned point on the network to check traffic from all devices on the network. It monitors data traffic over the subnet and compares data traffic sent on the subnet with known attack sets. As soon as an attack is detected or abnormal behavior is detected, a signal can be sent to the administrator. An example of NIDS is Installation on the subnet where the firewall is located to see if someone is trying to break into the firewall.
Host Intrusion Recognition System (HIDS):
HIDS (Host Intrusion Detection) systems work on independent hosts or devices on the network. HIDS only monitors incoming and outgoing packets from a device and notifies administrators when suspicious or malicious activity is detected. It takes a snapshot of the existing system files and compares it to the previous moment. If the analyzer file has been edited or deleted, an investigation notification is sent to the administrator. Examples of the use of HIDS can be seen on mission-critical machines that are not expected to change their layout.
Protocol-based intrusion detection (PIDS) system:
Protocol-based intrusion detection systems (PIDS) consist of systems or agents that are located one by one at the front end of the server and control and interpret the protocols between the user / device and the server. Attempts are made to secure the web server by regularly monitoring the flow of the HTTPS protocol and adopting the appropriate HTTP protocol. Since HTTPS is not encrypted and must be in this interface immediately before it can enter the web presentation layer, HTTPS must be used.
Penetration detection system based on application protocol (APIDS):
Application protocol-based intrusion detection systems (APIDS) are systems or agents typically located on a group of servers. It identifies intrusions by monitoring and interpreting communications according to application-specific protocols. For example, it will monitor the SQL protocol, which is explicit for software averaging when it performs transactions with a database on a web server.
Hybrid penetration detection system:
The hybrid penetration detection system is implemented through a combination of two or more approaches to the penetration detection system. In a hybrid intrusion detection system, the host agent or system data is combined with network information to develop an overall view of the network system. The hybrid penetration detection system is more efficient than other penetration detection systems. The introduction is an example of a hybrid IDS.
