Keep an eye on the network security status

Analyzing network traffic in huge companies is not quite the same as monitoring home network security. You can get a Certified Network Defender or try the following options:

Detect network data sources

The initial phase in monitoring and analyzing operating network traffic is to acquire visibility by joining data from a data source.

Find the PCs and programs that sudden spike in demand for your network

The next step is to discover the programs, gadgets, clients, VPNs, and interfaces running on your network.

Use network-specific productions

The particular networking tool you use can decide the success or failure of your network traffic monitoring. Even though most producers don’t need brand-specific network monitoring solutions for these products, these affirmations normally have exemptions.

Optimize your network traffic

Learn the most effective methods for becoming a network administrator

If you need to turn into a network security admin, you should be a certified network defender. You will require an MBA or Bachelor’s degree in a relevant field of Information and Computer Technology. A few providers also offer certification programs. The certificate confirms best practices and experience as network security admins.

About CND: Certified Network Defender

The Certified Network Defender (CND) is a certification program that trains smart network managers.

The CND certification program provides the certified network defender with actual and modern information on network security technologies and operations.

The best practices for intrusion detection and prevention systems in 2022

To get the most out of intrusion detection and prevention systems, organizations should follow these best practices.

Multi-technology IDP integration

There are advantages and disadvantages to each IDP technology. Selecting a single IDP technology will not guarantee network security. It takes a combination of these technologies to create a truly effective intrusion detection and prevention system. Your organization may need a combination of host-based and network-based deployment depending on your requirements. Furthermore, each of these may require the use of signature, anomaly, and protocol-based detection techniques. It is important to determine how the integration will work in these cases. While some IDP solutions feed information directly to other solutions, others feed information to a central software solution, such as a Security Information and Event Management (SIEM) solution.

Designing to reduce false positives

Reporting suspicious behavior to the administrator and expecting the administrator to take appropriate action is the most effective mechanism. Administrators may find this irritating.

By using all available resources, the system reduces the availability of resources for other operations. You’ll need more bandwidth for more complex solutions. Additionally, it can be deployed on separate networks with additional managed networks, servers, interfaces, and consoles. Before implementing any system, the trade-off between cost, efficiency, and resource consumption must be considered.

To fine-tune your simulations, run them regularly

It is difficult to examine intrusion detection and penetration networks by nature. To provide operators with additional layers of detection and penetration, some third-party vendors provide a learning or simulation mode. They can then refine their current settings and profiles. The result is dramatic reductions in false positives.

Stay informed

Detecting malware signatures is based on an updated and evolving database of known malware. Using the latest standards of the eligible supplier, the conditioning protocol is analyzed. Each vendor reviews and reimplements protocols regularly. These changes need to be reflected in protocol models and databases. This requires patch management.

Backup your data

The matching of IDP systems is difficult. Therefore, you should periodically back up the configuration settings in your networks. Before updating systems or making substantial changes to infrastructure, settings and profiles should also be backed up.

Ensure that the system is reliable and available

There is more to designing an intrusion prevention system than just deciding where to place the components. A fail-proof implementation of IDP also involves identifying which networks and their segments are critical. It is possible to monitor the same activity with different sensors or even with different management servers with built-in configurations. Consideration must be given to flexibility, redundancy, as well as load balancing. As IDPs are normally a part of a network, critical components of the system may go down as well. Consider this when deciding how to deploy IDPs.

If you’re looking for network availability, think of redundant links, link controllers, Service Providers’ redundancy, etc.

Think about NAC or some kind of IAM when it comes to authentication into the network

Also, it’s good to think of network segmentation using DMZs and VLANs in order to separate network flows that don’t need to interact.
