It is generally used as packet capturing tool. It breaks down packets and displays different traffic information used for real-time or offline analysis. It filters and zooms out root causes of problem which can ultimately help secure the network. In this chapter, a list of laboratory activities are done to introduce to you the functionality of WIRESHARK (Please see Topic Learning Outcome). With these activities, summarize the functionality of Wireshark that is being used for network security. Use the given format below. LIST AS MANY AS YOU CAN.

- Access Control Lists (ACLs) are used by firewalls (ACL). Explain what an ACL is and what it's usual contents look like. Explain what the word "salt" means in the context of cryptography and why it is used. You should go over how it is used to make it more difficult to break passwords and how it is implemented.SCENARIO 1: You have just completed a routine security audit on the company’s information systems, and you found several areas of vulnerability. For example, file permissions have not been updated in some time, no comprehensive password policy exists, and network traffic is not fully encrypted. You noted these areas, among others, in a report to your supervisor. The report included specific recommendations to fix the problems. Your supervisor responded by saying that budgets are tight right now, and she could not approve your requests to resolve these issues. As an IT professional, you are very uncomfortable with the risk level, but you have been unable to sway your supervisor. When you discussed the situation with a colleague, he said, “Why worry about it? If it’s good enough for her, it should be good enough for you.” What do you think of your colleague’s advice, and why? Is this an ethical question? If you are still is uncomfortable, what are your options? SCENARIO 2: You work for a…pls help me in my assignment.

- If an IT Security Manager has to detect zero day malware which type of IDPS Detection methods do you suggest and also select the right reason for your choice. O Statistical anomaly based. This can detect existing types of attacks/malware and known patterns Signature based. This can detect all types of attacks and unknown patterns as it has a database of all known signatures Network Behavior based. This can detect new types of attacks/malware and unknown patterns Signature based network type. This can detect existing types of attacks and unknown patterns in a networkConsider the following threats to Web security and describe how each is countered by a particular feature of SSL. Man-in-the-middle attack: An attacker interposes during key exchange, acting as the client to the server and as the server to the client. Password sniffing: Passwords in HTTP or other application traffic are eavesdropped. IP spoofing: Uses forged IP address to fool a host into accepting bogus data. IP hijacking: An active, authenticated connection between two hosts is disrupted and the attacker takes the place of one of the hosts. SYN flooding: An attacker sends TCP SYN message to request a connection but does not respond to the final message to establish the connection fully. The attacked TCP module typically leaves the “half-open connection” around for a few minutes. Repeated SYN messages can clog the TCP module.Suppose an organization uses a secure VPN to securelyconnect its sites over the Internet. Jim, a user in theorganization, uses the VPN to communicate with his boss,Mary. Describe one type of communication between Jim andMary which would not require use of encryption or othersecurity mechanism, and another type of communication which would require encryption or other security mechanisms. Please explain your answer.

Since the release of the ZeuS source code in 2011, many other malware variants have adopted parts of its codebase, which means that incidents classified as ZeuS may actually be other malware using parts of the original ZeuS code. https://www.cisecurity.org/insights/blog/top-10-malware-december-2022 Zeus malware can give attackers full access to infected machines. While the original Zeus variant primarily utilized man-in-the-browser keyloggers to gain access to an infected computer’s banking credentials and other financial information, many forms of the Zeus virus can also be used to add CryptoLocker ransomware to an operating system or add infected computers to a botnet to perform distributed denial-of-service (DDoS) attacks.
