Network Intrusion has become a norm in the digital age. Phishing attacks alone steal billions of dollars every year, according to FBI information. In a world where virtual attacks are less common and everyone is at risk no matter what the level of internet activity, there is no way you can get around without the right Intrusion detection and prevention systems. You may be an individual with a residential internet service like the current one at Spectrum packages or a company that takes advantage of a business internet service from one of the major providers; as long as you are connected to the internet, you are at risk of Intrusion.
Network Intrusion detection and prevention systems are used to detect attackers and block their malicious activity before any damage is done. These systems include both virtual and physical systems that scan network traffic either through the cloud or through on-premises. Read on to find out how these systems work and which ones are the best on the market.
Intrusion Detection System
An Intrusion detection and prevention system oversees the traffic passing through your network for any signs of unusual activity. As soon as it detects malicious activity, it takes action to stop it. This includes blocking network traffic, dropping malicious packets, or resetting the connection. It would also send an alert to the administrator, warning them of the suspicious activity detected and stopped.
There are two commonly used types of detection methods. One is based on signature detection, and the other is based on an anomaly. Signature-based detection uses previously identified risky activity to identify new attacks. If the new attack criteria meet the one previously stored in the system it will immediately stop the spying operation. The downside to this type of detection is that it does not detect or block new attacks.
On the other hand, the anomaly-based detection method runs a comparison between normal activity and the activity it knows to be normal. If any error is detected, it will alert the administrator as well as take action to prevent the attack itself. One great thing about it is that it finds new attacks as well. However, it can also cause false positives, but that can be solved by using some of the latest technology that uses artificial intelligence to set up algorithms to set a normal baseline.
Intrusion Prevention System
There are three types of intrusion prevention systems. Network-based intrusion prevention, host-based intrusion prevention, and wireless intrusion prevention system. Network-based prevention is more widely used and works directly behind the firewall. A firewall blocks traffic from entering the network, whereas IPS block traffic that is on the network but displays threat signs according to specific criteria that have been stored in previous memory. It is a hosted based system where it looks for dangerous activity among specific guest traffic. And banning wireless intrusion prevention has to do with monitoring and marking an unauthorized attempt to access a Wi-Fi network.
Setting Up Network Intrusion Prevention
Some organizations choose to set up independent network attack prevention systems but others decide to go for a unified threat management solution that prevents intrusion as well. There is also another option called the next-generation firewall which also includes intrusion prevention. This solution is specifically targeted at larger organizations but unified threat management targets small to medium-sized companies. These solutions are available as hardware as well as cloud-based. Companies choose according to their needs and preferences.
Some Top Intrusion Prevention Systems
Let’s take a look at the best IPS systems available in the market.
McAfee Network Security Platform
The McAfee NSP protects data and systems wherever they are, across the cloud, data centers, and hybrid enterprise environments. It uses artificial intelligence to detect and block any network attacks and can support up to 32 million connections on a single device.
Hillstone Network-Based Intrusion Prevention System
The Hillstone NIPS offers anti-virus, intrusion prevention, application control, abnormal behavior detection, advanced threat detection, cloud-based security management, cloud sandboxing, and analytical performance in a single device. It analyzes in-depth packets and compiles an analysis of all the traffic that passes through your network. It can identify over 3000 applications that include your mobile phone and cloud.
Trend Micro TippingPoint
The Trend Micro TippingPoint can identify and prevent malicious activity and lateral movement of malware. It ensures that your network is resilient and available, thus improving the performance of the network. It can be implemented immediately to filter unwanted and malicious traffic without entering your MAC or IP address. The digital vaccine threat intelligence filters focus on the overall vulnerability footprint rather than targeting specific attacks. It also offers traffic monitoring up to 120Gbps.
Darktrace Enterprise Immune System
The Artificial Intelligence technology of cybersecurity, this machine learning system learns the usage pattern of each user and device on the network. It then uses this information to identify any potential unknown hazards. The Darktrace Enterprise Security System is not seen as an IDPS solution and the company does not respond to the segment of companies that provide such solutions. However, it has been included in the list because of the great protection it provides.
Cisco Firepower Next-Generation Intrusion Prevention System
Anyone from a small office set up to a large enterprise can use the next-generation Cisco Firepower Intrusion Prevention System. It comes in both physical and software formats offering URL-based network security as well as AMP Threat Grid integration. Providing transmission between 50Mbps to 60 Mbps, it is supported by Cisco’s Talos security research team.
We hope this article has helped you to better understand what network Intrusion is and how the detection and prevention systems work. Now that you know about some of the best systems available in the market, you need to choose one that suits your preferences and the requirements of your organization. We are sure that you have some cybersecurity system but these systems will make the system open so that you can do your online activity with complete peace of mind.
