Intrusion Detection System (IDS) vs Intrusion Prevention System (IPS) vs Firewall IDS, IPS, and Firewall talk about providing security to network and are described as principal components of a Network especially Data Center Network.  Firewall : Firewall is a network security device that filters incoming and outgoing network traffic based on pre-determined security rules. Main working nature of firewall is it filters traffic based on IP address and port numbers. It is configured in layer3 mode or transparent mode. It would be placed inline at the perimeter of the network. Traffic patterns of Firewall are not analyzed. Firewall blocks the detected unauthorized traffic on the network. In brief, Firewall is a device or application that analyzes packet headers and enforces policy based on protocol type, source address, destination address, source port, and/or destination port. Packets that do not match policy are rejected. Intrusion Detection System (IDS) – It is a sof...

Cryptocurrency A cryptocurrency is a digital currency in which encryption techniques (cryptography) are used to regulate the generation of units of currency and verify the transfer of funds, operating independently of a central bank. The first cryptocurrency created was Bitcoin back in 2009. Today, there are hundreds of cryptocurrencies, often referred to as Altcoins. The popularity of cryptocurrency has also increased the rise in the number of crypto exchanges in the market lately. Undoubtedly, there’s a great opportunity in this area to make a profit on crypto trades. At the same time, being a naïve and unregulated market for cryptocurrencies, it has become prey for hackers. A report in the Wall Street Journal  shows more than $US800 million worth of cryptocurrency has been stolen by hackers this year. The figures are based on an investigation by Autonomous Research, an independent research provider for the finance industry. We cannot recover stolen cryptocurrency ...

Network Security:             A group of computers connected together to form to be a Network.  All of those interconnected devices communicate with each other to perform the tasks assigned to them. These networks form the hubs and the life for many of the software giants as they deal with the accessing of the corporate information and the confidential data. Authentication is the procedure in which the user is asked to provide the details like his username and the password. After he tries to login with those details he is then allowed to access a certain part of the database or the system only if his authentication is successful. This normal and simple form of the authentication is called one-time authentication. There are also several other forms of authentication like two-factor authentication in which the user also has something to use like his card or swipe cards to obtain permissions in addition to his login details als...

Cyber attackers are using more and more sophisticated technologies and automated tools to launch their attacks on the targets. As soon as they find a vulnerability in network, application, or simply anywhere, within minutes to hours, they intrude, compromise and steal the data. With this scenario, responding to attacks and time to remediation is essential for the organizations. This kind of quick response may not be possible with traditional methods. It may take several days for the IT/Security teams to collate the data, analyze traffic trends and to establish the type of data breach context.  According to a research conducted in IT industry, suggests it take 146 days for them to react to any Cybersecurity threats. For this reason, to address this time-critical challenge, IT industry is exploring Artificial Intelligence option. Using AI may be the best bet for organizations, especially for the companies deal with consumer data to protect their networks ...
