Given have a firewall between the Internet (represented by a cloud) and your network router. And some active attacks are added from the list of active attacks; os exploits, viruses, trojans, etc. Please refer to the diagram attached. Are these attacks able to get to your network? Do you feel your system is secure? What’s wrong with this scenario? please don't copy the solution on Bartleby. it does not answer the question

You are given the following “informal firewall policy” details to be implemented usinga firewall like that in the following figure: 1. E-mail may be sent using SMTP in both directions through the firewall, but it must be relayed via the DMZ mail gateway that provides header sanitization and content filtering. External e-mail must be destined for the DMZ mail server.2. Users inside may retrieve their e-mail from the DMZ mail gateway, using either POP3 or POP3S, and authenticate themselves.3. Users outside may retrieve their e-mail from the DMZ mail gateway, but only if they use the secure POP3 protocol and authenticate themselves.4. Web requests (both insecure and secure) are allowed from any internal user out through the firewall but must be relayed via the DMZ Web proxy, which provides content filtering (noting this is not possible for secure requests), and users must authenticate with the proxy for logging.5. Web requests (both insecure and secure) are allowed from anywhere on the…
1. Given that sessions hold users' authenticated state, the fact of compromising the session management process may lead to wrong users to bypass the authentication process or even impersonate as other user. Propose some guidelines to consider when implementing the session management process. 2. When creating a password, some applications do not allow password such as 1111 aaaaa, abcd. Why do you think this practice is important
Consider the following security threats and describe in your own words how each types of attacks are countered by Secure Shell (SSH). a. Impersonation Attack: the attacker impersonates a SSH server to clients. b. Replay Attack: the attacker replays a command from the client to the server. c. Reflection Attack: An attacker reflects a message sent by a client back to the client. d. Password Sniffing: Passwords in user authentication are eavesdropped.
Can you please help with these questions: What is the difference in detail captured between NetFlow, firewall logs, and raw packet captures? Which would be more useful in investigating malware? Which types of network logs/capture would take more storage space? What kinds of things could firewall and NetFlow logs be useful for over raw packet captures?.
