Intrusion detection systems (IDPs) come in a variety of different configurations. Some systems are host-based while others can be network-based. There are even Blockchain-based idps. What are the benefits and drawbacks of these systems? Here are some examples.
Host based intrusion prevention system
Host based intrusion prevention system, also known under HIDS (or host-based intrusion prevention systems), are software solutions that monitor and control activities on a single computer. These systems have many of the same advantages as application-level intrusion prevention systems but are smaller in scale. They must communicate their findings with a central surveillance system, which may be unavailable during active attacks.
Host-based IPSs can protect against a variety of attacks. They protect against spam and viruses, Trojan horse software, keyloggers as well buffer overflows, rootkits and Denial of Service attack. They often have integrated firewall capabilities.
Intrusion prevention systems based on network technology
Network-based intrusion prevent systems (NIPS), use a combination signature-based as well as anomaly-based detection algorithms in order to detect and stop malicious activity. While signature-based approaches work best to block known attacks, they can also be inaccurate and lead to false positives. NIPS should work at both the application-level and network-level firewall processing to block new threats.
Network-based intrusion protection systems analyze traffic flow and examine signatures. These systems generally use special-purpose hardware. But, some systems can be software-based. Software-based approaches may be sufficient for small and midsize businesses. For large-scale companies, however, specialized hardware may be required. Dedicated network security processors and application-specific integrated circuits will likely be required.
Cloud-based intrusion prevention system
There are many different types, and it is important for you to choose the one that best suits your needs. One type of system is preferred by some companies. Microsoft Intelligent Defense Protection System, for example, has a scalable IDPS. It was developed by Microsoft after it recently invested $20B in cybersecurity research. This system analyzes traffic to determine the risk of network assets. The pricing is very affordable, with a starting price of $1.75 per hour for deployment and $0.016/GB processed. Blumira and other companies offer more comprehensive solutions.
An IDPS's key benefit is its ability to keep detailed logs. This allows administrators to see the events occurring on their network. Additionally, these systems can generate ad-hoc reports to meet compliance requirements. Many of these systems are capable of automatically responding to identified threats.
Blockchain-based idps
The blockchain-based IDPS system is revolutionary in securing data. Its open, decentralized architecture ensures data security, accountability and traceability. These systems can help protect against fraud and prevent other types of misuse. Although they are not free, these systems can be very efficient in protecting data.
Blockchain is being used to secure information in many industries, including health-care, supply chain management, and the Internet of Things. Its robust cryptography, decentralized architecture, and robust cryptography make it more secure than peer-to–peer networks. No third party is required. The blockchain can be used to track and identify quality, detect inefficiencies, and track supply chain items in real time. Microsoft is also researching the benefits from blockchain-based IDPs.
