CIS608 - Week6 - Common threats to Computer Network

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...

CIS608 - Week9 - WannaCry - Ransomeware

WannaCry - Ransomware On May 12, 2017, IT world witnessed new ransomware called WannaCry and it impacted 300,000 immediately. This ransomware exploits the vulnerabilities in the Windows file-sharing protocol. The infiltration of this threat is through and point devices such as Windows devices that allowed inbound SMB communications on firewall ports 139 or 445 and had not been updated with the latest Microsoft security patch. Once a device had been exploited, the malware would scan for other vulnerable devices and spread over. The way Ransomware works is - once it infects, it encrypts, scrambles the data and then it demands to payout in cryptocurrency. The clients will always think whether to pay out for removing the ransom or replacing the system affected depending on the value of the data being attacked and replacement costs. It is not always true that the hijacked data can be retrieved, reinstalled and never be exported when payments are made. Dep...

CIS608 - Week5 - Enhancing Cyber Security with Artificial Intelligence

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 ...
