Why deploy ips

Policies are key elements that contain rules for allowing or blocking network traffic and inspecting the content of traffic.

User accounts are stored in internal databases or external directory servers. Maintenance includes procedures that you do not typically need to do frequently.

The scenario presented here is not meant to be representative of a typical installation. The main focus here is to highlight some of the criteria that you can use when planning your deployment. The example covers considerations that affect most installations, but is not an exhaustive list of the factors you might need to consider. The IPS system could be deployed in alternative ways even in this example scenario, depending on issues that are not covered here, such as the physical layout of the individual local networks, the hardware available, and budget constraints.

This example explains the IPS deployment at a company that has three offices: headquarters in London, a branch office in Munich and a small satellite office in Vienna. All offices have IPS components. There are also SMC components at the two larger sites. The example company has some critical assets to protect and some of the networks experience a heavy traffic load. The example company has decided on a High Availability solution for most locations and acquired the following components:.

Home Deployment Before you can set up the system and start configuring elements, you must consider how the different SMC components should be positioned and deployed.

What is IPS Security? IDS can be either network-based or host-based: Network-based intrusion detection systems NIDS have sensors strategically placed within the network, sometimes at multiple locations, to monitor as much traffic as possible without creating performance bottlenecks. Host-based intrusion detection systems HIDS run on specific hosts or devices, monitoring the traffic associated with them. IPS security can detect the same kind of malicious activity and policy violation that an IDS does, and can additionally respond in real time to stop immediate threats: Like an IDS, IPS can be network-based with sensors at various points of the network or host-based with sensors on the host to monitor individual devices.

Unlike the IDS, IPS has the ability to configure policy-based rules and actions to be executed when any anomaly is detected. IPS can save time for security teams, while IDS adds more alerts that security teams need to analyze and act upon. Attack Description DDoS Attacks An attempt to make a server, service, or network unavailable by overwhelming it with a flood of traffic from multiple, distributed computing systems. Ping of Death A DoS attack in which an attacker attempts to crash a system by sending malformed or oversized packets, using a ping command.

Port Scanning Attack Attackers send requests to a range of server ports, with the goal of finding an active port and exploiting its vulnerability. Buffer Overflow Attacks Attackers exploit buffer overflow vulnerabilities, corrupting the execution path of an application by overwriting parts of its memory.

OS Fingerprinting Attacks Attackers attempt to identify the operating system of a specific target and exploit its vulnerabilities.

They protect networks from known threats with a limited time investment by the security team.

Search Cyberpedia Search. Prevention The IPS often sits directly behind the firewall and provides a complementary layer of analysis that negatively selects for dangerous content. Specifically, these actions include: Sending an alarm to the administrator as would be seen in an IDS Dropping the malicious packets Blocking traffic from the source address Resetting the connection As an inline security component, the IPS must work efficiently to avoid degrading network performance.

Detection The IPS has a number of detection methods for finding exploits, but signature-based detection and statistical anomaly-based detection are the two dominant mechanisms. Signature detection for IPS breaks down into two types: 1. Exploit-facing signatures identify individual exploits by triggering on the unique patterns of a particular exploit attempt. The IPS can identify specific exploits by finding a match with an exploit-facing signature in the traffic stream 2. Vulnerability-facing signatures are broader signatures that target the underlying vulnerability in the system that is being targeted.

These signatures allow networks to be protected from variants of an exploit that may not have been directly observed in the wild, but also raise the risk of false positives. Get the latest news, invites to events, and threat alerts.
