A network intrusion detection system (NIDS) can be an integral part of an organization's security, but they are just one aspect of many in a cohesive and safe system. They have many great applications, but there are also weaknesses that need to be considered. It is important to compare an NIDS against the alternatives, as well as to understand the best ways to implement them.
Intrusion detection systems are a lot like fire alarms. Just as a fire alarm detects smoke, an intrusion detection system idenitifies incidents and potential threats. They are incredibly useful for raising awareness, but if you don't hear the alarm or react appropriately, your house may burn down.
While a firewall is there to keep out malicious attacks, an IDS is there to detect whether someone or something is trying up to suspicious or nefarious activity. When it detects something, it notifies the system administrator.
An IDS is a visibility tool that sits off to the side of the network and monitors traffic. It consists of a management console and sensors. When the sensors encounter something that matches up to a previously detected attack signature, they report the activity to the console. An IDS can notify security personnel of infections, spyware or key loggers, as well as accidental information leakage, security policy violations, unauthorized clients and servers, and even configuration errors.
An IPS is similar to an IDS, except that they are able to block potential threats as well. They monitor, log and report activities, similarly to an IDS, but they are also capable of stopping threats without the system administrator getting involved. If an IPS is not tuned correctly, it can also deny legitimate traffic, so they are not suitable for all applications.
An NIDS and an HIDS are complementary systems that differ by the position of the sensors: network-based (monitoring the ethernet or WiFi) and host-based, respectively. Because of this, their uses and deployment are quite different.
Network-based sensors have a quicker response than host-based sensors and they are also easier to implement. An NIDS doesn't need to alter the existing infrastructure and they monitor everything on a network segment, regardless of the target host's operating system. As they do not need software loaded and managed at the different hosts in the network, they have a lower cost of setup and ownership.
An NIDS can detect attacks that an HIDS will miss because it looks at packet headers in real-time. In saying this, an HIDS will also be able to pick up some things that an NIDS will miss, such as unauthorized users making changes to the system files. An HIDS monitors event and audit logs, comparing new entries to attack signatures. This is resource intensive, so your organization will need to plan for the additional hardware required.
Another benefit of an NIDS is that they detect incidents in real-time, meaning that they can log evidence that an attacker may otherwise try to erase. While the real-time detection abilities of an NIDS allow for quicker responses, they also turn up more false positives than an HIDS. Hybrid NIDS and HIDS solutions that combine aspects of both systems are also available and can be useful in different scenarios.
They Can Be Tuned to Specific Content in Network Packets
Firewalls may be able to show you the ports and IP addresses that are used between two hosts, but in addition a NIDS can be tuned to show you the specific content within the packets. This can be used to for uncovering intrusions such as exploitation attacks or compromised endpoint devices that are part of a botnet.
When an NIDS performs protocol analysis, it looks at the TCP and UDP payloads. The sensors can detect suspicious activity because they know how the protocols should be functioning.
An IDS analyzes the amount and types of attacks. This information can be used to change your security systems or implement new controls that are more effective. It can also be analyzed to identify bugs or network device configuration problems. The metrics can then be used for future risk assessments.
Because an IDS gives you greater visibility across your network, they make it easier to meet security regulations. You can also use your IDS logs as part of the documentation to meet certain requirements.
Because IDS sensors can detect network devices and hosts, they can inspect the data within the network packets and identify the services or operating systems that are being utilized. This saves a lot of time when compared to doing it manually. An IDS can also automate hardware inventories, further reducing labor. These improved efficiencies can help to reduce an organization's staff costs and offset the cost of implementing the IDS.
An IDS does not block or prevent attacks, they merely help to uncover them. Because of this, an IDS needs to be part of a comprehensive plan that includes other security measures and staff who know how to react appropriately.
An IDS is immensely helpful for monitoring the network, but their usefulness all depends on what you do with the information that they give you. Because detection tools don't block or resolve potential issues, they are ineffective at adding a layer of security unless you have the right personnel and policy to administer them and act on any threats.
An IDS cannot see into encrypted packets, so intruders can use them to slip into the network. An IDS will not register these intrusions until they are deeper into the network, which leaves your systems vulnerable until the intrusion is discovered. This is a huge concern as encryption is becoming more prevalent to keep our data secure.

The information from an IP packet is read by an IDS, but the network address can still be spoofed. If an attacker is using a fake address, it makes the threat more difficult to detect and assess.
One significant issue with an IDS is that they regularly alert you to false positives. In many cases false positives are more frequent than actual threats. An IDS can be tuned to reduce the number of false positives, however your engineers will still have to spend time responding to them. If they don't take care to monitor the false positives, real attacks can slip through or be ignored.
An NIDS analyzes protocols as they are captured, which means that they face the same protocol based attacks as network hosts. An NIDS can be crashed by protocol analyzer bugs and also invalid data.
An IDS is only as good as its signature library. If it isn't updated frequently, it won't register the latest attacks and it can't alert you about them. Another issue is that your systems are vulnerable until a new threat has been added to the signature library, so the latest attacks will always be a big concern.
The benefits of an intrusion detection system: How it can boost your network security
If you're like most business owners, you are probably always looking for ways to tighten your network's security. One way to do that is by installing an intrusion detection system (IDS). An IDS provides a number of benefits that can help keep your business's data and networks safe from a wide variety of threats. Moreover, IDS offers an invaluable layer of protection that conventional perimeter security systems don't provide.
Here's some essential information about intrusion detection systems and the ways they can protect your business's vital data and networks.
An IDS helps detect and respond to any malicious activities on a computer network by monitoring for suspicious activity, such as unauthorized access attempts or data manipulation. IDS has many uses but it is particularly helpful in preventing attackers from stealing sensitive information or gaining access to privileged accounts.
The main reason to install an IDS, however, is to detect intrusions fast and accurately. To do this, IDS uses either signature-based detection or anomaly-based detection. Signature-based detection involves searching through network traffic for specific patterns associated with known attacks. On the other hand, anomaly-based detection involves examining the activity on the network and flagging anything that doesn't fit common patterns as possibly malicious.
When an intrusion is detected, an IDS will usually alert the user and/or the system administrator. It may also take further action depending upon its configuration, such as blocking or logging out certain users, disabling certain services, or even shutting down the system itself if necessary. This is to ensure that any threats are dealt with immediately before they cause harm to the network.
Like an IDS, an intrusion prevention system (IPS) can detect suspicious traffic, but a key difference is that an IPS actively blocks any such traffic rather than just alerting administrators about it. It's more proactive at preventing attacks compared to an IDS, which typically only issues alerts after a breach has already occurred.
Here are the ways that an IDS can boost your network's protection:
IDS solutions are able to detect unusual or suspicious activity on a network, which can be a sign of a potential security weakness or vulnerability. This helps administrators identify any possible weak points in the network that need to be patched up in order to prevent future attacks.
By detecting intrusions fast, an IDS can help reduce the risk of data loss that may be due to malicious activity or unauthorized access. This is especially important for businesses and organizations that store sensitive or confidential data on their cloud systems, as any security breach could have devastating financial or reputational consequences.
Traditional signature-based detection systems may identify and block known threats, but an IDS takes threat detection a step further. It vigilantly watches for suspicious behavior beyond just identifying preprogrammed entries in its database of known threats.
To illustrate, antivirus software only offers a reactive solution, whereas an IDS is capable of both analyzing and responding to potential threats in real time, making it more effective at mitigating the risk of cyberattacks.
An IDS provides administrators with greater visibility into their networks, allowing them to quickly identify and address any potential threats. The system also allows for detailed monitoring of user activities, which can help determine if users are engaging in suspicious activity or showing malicious behavior that could lead to a security breach. And when administrators can spot any suspicious activity early, they can take the necessary steps to prevent any further damage.
Many industries are subject to various government and industry-specific regulations when it comes to data security, such as the Payment Card Industry Data Security Standard (PCI DSS). Intrusion detection systems can help organizations meet these regulations by providing an extra layer of security to ensure that all data is protected from unauthorized access.
