Interscale Content Hub – As digital threats keep getting more sophisticated, it’s more important than ever to have a good IDS cybersecurity strategy in place.
Intrusion Detection Systems (IDS) work like a network’s own security team, keeping a close eye on traffic and spotting any suspicious activity that might signal a cyberattack.
So, let’s break down the different parts of an IDS cybersecurity strategy.
Definition of IDS (Intrusion Detection Systems)
Intrusion detection is basically just keeping an eye on what’s going on in a computer system or network and looking for signs that someone’s trying to break in.
That could mean trying to steal your data, mess with your system, or even get around your security measures.
These systems do two things: they keep an eye on network traffic and system activities, looking out for anything suspicious, and they work with other security measures like firewalls and antivirus solutions to make the whole system stronger.
IDS systems work by looking at data traffic to spot patterns or irregularities that might indicate malicious activity.
If something looks suspicious, the system will flag it and either send it to an administrator or to a central security information and event management (SIEM) system.
This integration helps security teams respond more quickly to threats.
For instance, ransomware has been a major threat for a while now, and it’s only going to get worse.
Types of Intrusion Detection Systems
According to NIST’s special publication on intrusion detection systems, IDS are grouped into different types based on how they monitor and analyze things.
Each type of IDS is designed to meet a different security need in networks and computers.
Network-Based IDS (NIDS)
These systems monitor and analyze network traffic to identify suspicious activities that could indicate threats.
By placing sensors across the network, NIDS can detect attacks that target multiple devices, offering a broad security monitoring coverage.
They’re especially effective in environments where network traffic needs constant monitoring.
However, their effectiveness can be limited in high-traffic networks or when dealing with encrypted traffic.
Host-Based IDS (HIDS)
These systems are installed on individual hosts or devices to monitor and analyze their operational behavior.
HIDS can detect attacks that involve changes to files and system configurations, providing detailed visibility into specific system activities.
They are particularly useful for catching attacks that a NIDS might miss, such as those that alter local files or misuse local applications.
Application-Based IDS
Focused on specific applications, these IDSs monitor and analyze the behavior of individual applications for suspicious activities.
They are effective in environments where particular applications are critical to business operations and need dedicated monitoring.
This type of IDS can detect anomalies in how applications are accessed and used, offering protection tailored to specific application vulnerabilities.
Signature-Based Detection
This method involves detecting known attack patterns or signatures.
It’s highly effective for identifying well-documented threats but requires regular updates to signature databases to protect against new attacks.
Anomaly-Based Detection
This approach involves building a baseline of normal activity and then detecting deviations from this baseline.
It can potentially identify novel attacks that signature-based detection might miss.
However, it may also generate higher false positives, requiring careful tuning and management.

What is the Difference Between IPS and IDS?
IDS and Intrusion Prevention Systems (IPS) play 2 different but important roles in network security.
An IDS basically just monitors network traffic and lets the admin know if anything looks suspicious.
This lets you know when something fishy is going on and gives them the chance to respond.
On the other hand, an IPS not only spots threats but also stops them in their tracks by blocking or reducing the impact of those threats before they can cause any harm.
This makes IPS a kind of control mechanism within the traffic flow itself.
It’s important to use both IDS and IPS in your security strategy. By combining these systems, you get a layered defense approach that helps you detect and respond to security incidents.
By combining the wide coverage of detection provided by an IDS with the active threat prevention capabilities of an IPS, organizations can really improve their security posture.
This combo is really effective against all kinds of cyber threats, from malware and ransomware to more advanced zero-day exploits and insider threats (R3).
If you deploy both systems in the right way, you’ll get better protection. The IDS will keep an eye on any potential threats and log them, while the IPS will work to stop any threats that are identified from affecting the network.

IDS Tools and Software
Snort, Suricata, and Zeek are the top IDS tools out there, catering to all kinds of cybersecurity needs.
Snort is known for its great community support and a really extensive plug-in framework, which makes it really adaptable and effective in all kinds of network environments.
Suricata got a multi-threaded architecture that makes better use of hardware resources, so it can handle high network traffic more efficiently.
It also supports the latest network functionalities like hardware acceleration and complex threat detection through deep packet inspection.
Zeek is different because it focuses on event-driven analysis. This means it translates network activities into discrete events, which can be scripted for more sophisticated detection and response actions.
This makes it great for complex threat detection and network research, but it might take a bit of getting used to because it’s script-based.
Each of these tools can be scaled up or down to fit your needs, and you can customize them to fit into any organizational security framework you want.
