Intrusion detection systems (IDPs) come in a variety of different configurations. Some are host-based and others are network-based. Blockchain-based Idps are available. What are the benefits and drawbacks of these systems? Here are some examples.
Host-based intrusion protection systems
Host-based intrusion protection systems, also known by HIDS or HIDS, monitor the activities of one computer. These systems offer many of the same benefits as application-level intrusion detection systems, but are smaller in scale. They must inform a central monitoring station of their findings, which may not always be possible during active attacks.
Host based IPSs can protect against many attacks. They protect against spam and viruses, Trojan horse software, keyloggers as well buffer overflows, rootkits and Denial of Service attack. Many also have 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. Signature-based methods are most effective for blocking known threats, but they can sometimes be inaccurate and result in 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 typically use special-purpose hardware, although some can be software-based. Small to medium-sized businesses may find it sufficient to use a software-based approach. For large-scale businesses, however, you will need specialized hardware. Dedicated network security processors and application-specific integrated circuits will likely be required.
Cloud-based intrusion prevention systems
There are many types of intrusion prevention systems. It is important to know which one will best suit your needs. Some companies specialize only in one type or another. Microsoft Intelligent Defense Protection System, a scalable IDPS, is one example. Microsoft recently invested $20 billion to cybersecurity research. This system analyzes traffic and computes the risk of network assets. The price is very reasonable at just $1.75 an hour and $0.016 for each GB processed. Blumira offers more complete solutions.
An IDPS has a key advantage: it keeps detailed logs that allow administrators to view the events on their network. These systems can generate ad hoc reports to satisfy 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 to prevent fraud and other forms of misuse. While these systems may not be free, they can be extremely effective in protecting data.
Blockchain is used to protect information in many industries including healthcare, 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. Blockchain can also work in supply chains to detect inefficiencies and track items in realtime. Microsoft is also looking into the benefits of blockchain-based IDPs.
