Host-based IPS or network-based IPS
Posted: Sun Jan 05, 2025 9:01 am
IPS can be deployed at one of two levels:
Host: A host-based IPS protects the host on which it is installed, typically a single device. A host-based IPS provides deeper, more granular protection for a single device and its local files. It can also help you detect attacks originating from the device, such as programs inserted via a flash drive.
Network : Network-based IPS protects the entire network . It provides better visibility than host-based IPS and can also protect specific endpoints containing vital data before they are attacked.
IPS or IDS?
IDS stands for Intrusion Detection System. These two cybersecurity measures are often confused with each other. This is because most products have both, and an IPS is overseas chinese in worldwide database essentially just a proactive IDS. The main difference between the two is that an IPS proactively tries to stop threats , while an IDS simply detects their existence. When a threat appears, both IPS and IDS comb the network for suspicious packets. The differences begin to show once they find them. An IDS will simply acknowledge the packet or send you a notification. An IPS does both, and also drops suspicious packets. The advantage of an IPS is that it is great at preventing attacks , while an IDS has no chance of affecting your processes due to a false positive .
Two methods of threat detection
Signature-based detection : This is a detection method where traffic is compared to a pre-existing threat database. Action is taken only if the traffic instance has the same “signature” as one of the threats in the database.
Anomaly-based detection: This threat detection method works by creating a baseline of your network activity. It then compares all traffic to this baseline. If there is a significant deviation, it will take action. This is the better of the two options for preventing a zero-day attack, as a signature-based detection system may not have a suitable signature. On the downside, they are much more difficult and expensive to develop .
