why use an IDS / IPS?

An IDS / IPS allows us to have a complete monitoring of the flow and state of the components of the network or system, allows to maintain a control in case attacks or anomalies are detected, including those originating from the secure portion of the network, and that without the need to be present at the time of an attack, the IDS / IPS will be configured to act in automatic response to the event presented, and will allow us to have a record of everything that has occurred for subsequent analysis and improvement of the security of the infrastructure.

IDS / IPS systems detect attacks in real time while generating minimal impact to the network, are independent of the operating system, easy to configure and can protect a complete subnet.



The IDS / IPS allow the easy incorporation of other complementary tools of computer security, maximizing its potential, being for these reasons considered an important complement for the protection of an infrastructure.

IDS - Intrusion Detection System Features

However, for an IDS to really be an efficient security mechanism, it must have some characteristics. According to Ned (1999), an IDS tool must have the following characteristics:

1. be executed continuously, without human interaction and be safe enough, to allow its operation in promiscuous mode;

2. be fault tolerant, so that your knowledge base does not become inconsistent;

3. resist attempts to change your knowledge base, maintaining monitoring to ensure your security;

4. provide the minimum impact on the functioning of the system;

5. be able to detect changes in the normal functioning of the system;

6. be easy to configure, so that any changes can be made quickly;

7. cover changes in the system over time, as in the case of a new application that starts to be part of the system;

8. be able to minimize the probable errors of intrusion detection and analysis.

When we spoke earlier about minimizing possible evaluation errors, reference was made to the following types of errors in the  intrusion detection and prevention systems tool, for example:

1. false positive - occurs when the tool classifies an action as a possible intrusion, although, in fact, it is a legitimate action;

2. false negative - occurs when a real intrusion occurs, but the tool allows it to pass as if it were a legitimate action;

3. subversion - occurs when the intruder modifies the operation of the IDS tool to force the occurrence of false negatives.

Types of IDS

Now that you have understood how IDS / IPS works, it is important that you know some types and their differences:


Types of IDS Security

Host-based Intrusion Detection Systems (HIDS)

In the case of this system, IDS is installed on each monitored machine, to analyze the events recorded in the log files, or by the audit agents. It works as a last line of defense, in case the attack was successful and managed to get through the firewall and the NIDS.

With HIDS it is possible to detect the following situations: Incorrect and exaggerated use of memory; Processes whose behavior is suspicious Suspicious connections on the network; Use of CPUUse of System Calls; Detailed use of the disk.

Network-based Intrusion Detection Systems (NIDS)

Instead of monitoring a single computer, NIDS monitors the network as a whole. It monitors the traffic of the network segment in which it is inserted, with its network interface acting in an unseemly way.

Detection is done by capturing and analyzing packet headers and contents, which are compared with established standards or signatures, being an effective mechanism against attacks such as port scanning, IP spoofing, SYN flooding.

The use of multiple NIDS in a network guarantees a comprehensive form of defense. The network-based detection system consists of two main components, the sensors and the management station.

The sensors are the devices placed in certain points of the network, which perform the monitoring itself. The management station is responsible for the remote management of all sensors.

The NIDS operating with these particularities is able to have a greater range in the detection of intruders, compared to HIDS. A great positive point is that the NIDS has the property of not being visible to the attacker, causing the attack to be carried out without care.

Other advantages of NIDS are, according to Carvalho (2005): network performance is not affected; detection and identification of attacks is done in real time, facilitating immediate decision making; effectiveness in detecting port scanning; it is not restricted to only detecting attacks, but also to unsuccessful attack attempts.
