IDS: Intrusion detection system, IPS: Intrusion prevention system
they both are in hardware as well as software.
It depends on the corporate that which they want to implement either software or hardware.
IDS: It can only detect the malicious activity but can’t stop it because it is not placed inline. IDS generates the alert and sends it to IPS and it takes action to stop that malicious thing.
the placement of IPS is inline.
Types of IDS:
- NIDS: network intrusion detection system
- NNIDS: network node intrusion detection system
- HIDS: host intrusion detection system
- It monitors the whole traffic of the network
- thus, it monitors the network traffic of a single system.
however, it is just like antivirus or can say the enhanced version of antivirus.
How Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) Work?
Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) are however both parts of the network infrastructure. also, IDS/IPS compare network packets to a cyber threat database containing known signatures of cyberattacks — and flag any matching packets.
Intrusion Detection Systems (IDS):
analyze and monitor network traffic for signs that thus indicate attackers are using a known cyberthreat to infiltrate or steal data from your network. therefore, IDS systems compare the current network activity to a known threat database to detect several kinds of behaviors like security policy violations, malware, and port scanners.
Intrusion Prevention Systems (IPS):
live in the same area of the network as a firewall, between the outside world and the internal network. IPS proactively deny network traffic based on a security profile if that packet represents a known security threat.
IDS and IPS are Critical for Cybersecurity
Security teams face an ever-growing threat of data breaches and compliance fines while continuing to struggle with budget limitations and corporate politics. IDS/IPS technology covers specific and important jobs of a cybersecurity strategy:
Automation: IDS/IPS systems are largely hands-off, which makes them ideal candidates thus for use in the current security stack. IPS provides the peace of mind that the network is protected from known threats with limited resource requirements.
Compliance: Part of compliance often requires proving that you have invested in technologies and systems to protect data. Implementing an IDS/IPS solution checks off a box on the compliance sheet and addresses a number of the CIS Security controls. More importantly, the auditing data is a valuable part of compliance investigations.
Policy enforcement: IDS/IPS are configurable to help enforce internal security policies at the network level. For example, if you only support one VPN, you can use the IPS to block other VPN traffic.
