Partnering with managed IT services providers in Orlando is an excellent choice to achieve sophisticated network security for protection against hacking attempts. Business technology systems face various vectors of cyber threats that can’t be thwarted with standard firewall systems.
Managed service providers (MSPs) offer intrusion detection systems (IDS), which provide an additional layer of protection to firewalls and anti-virus software.
However, IDS solutions are split into two divisions: network-based and host-based. These intrusion detection systems monitor your network for specific malware threats and traffic anomalies, which inform a reaction to frustrate attacks. Here’s a brief overview of how intrusion detection systems work:
Network-Based Intrusion Detection System
Managed IT services providers in Orlando deploy network-based intrusion detection systems (NIDS) at strategic points in the network to allow monitoring of traffic to and from all nodes on your networking infrastructure. This helps to mitigate network penetration attacks.
In reality, the NIDS scan both inbound and outbound traffic. Although the NID system may negatively impact network speed, it allows for a thorough scanning of network connections to block malicious activity.
Host Intrusion Prevention
Host-based Intrusion Detection Systems (HIDS) are configured at the device-level to protect workstations from intrusion. HIDS facilitate the close monitoring of inbound and outbound packets from a specific device and sends alerts to the IT administrator or user when a suspicious data packet or network activity occurs.
For both the NIDS and HIDS to detect and respond to suspicious network activity, they use the following components:
Sensor - This is the packet capture and behavioral signature detection engine. It uses an established baseline of a signature database to detect malicious packets. Advanced IDS have inbuilt behavioral activity capabilities to prevent network attacks.
Backend - The component that houses the event-recording database and fires alerts to the user. All suspicious events that have been recorded are reported via database logs, email, and SNMP traps. However, the backend also allows for a response to threats, such as blocking a specific connection by forcing a TCP reset.
Frontend - It houses the user interface and the command and control functionality for security enforcement. It allows the user to view events, update the signature database, and the behavioral detection engine.
Still, IDS allow for specific configuration to detect threats to your networks based on a database of malicious signatures and the use of predefined proactive settings to address imminent threats. In turn, they provide a reliable solution for proactive network monitoring.
