Step by step
Solved in 4 steps
- Describe a situation in which two different computing machines are collaborating to share a video clip by means of an unsecured ftp connection, which exposes the TCP three-way handshake to a potential security risk.What is the router's boot procedure?Being "out of band" means that one is not present for a certain performance. Why is it necessary to swap keys outside of the encryption channel while working with symmetric encryption?
- The FTP port numbers must be documented. Does FTP, as is often thought, send control data "out of band"?What are the advantages of placing cryptographic algorithms at the network layer? 1. Applying an authentication algorithm on an IP packet in the transport mode will affect routing this packet and so a gateway is not needed to route the packet. 2. It is impossible to obtain a port number from an encrypted IP packet in the transport mode. 3. Encrypting payloads only will make it impossible to analyze traffic. 4. Application-layer applications will not be affected by encryption or authentication algorithms. 5. Encrypted IP packets in the tunnel mode are not visible to the gateways on the routing path. 6. Applying an encryption algorithm on an IP packet in the tunnel mode will make it impossible to route this packet and so a gateway is needed to route the packet.Explain what the following rule will accomplish and why it is necessary when applied to traffic entering a firewall from the Internet in a succinct manner. If status flag tcp syn = 1 and status flag tcp fin = 1, then DENY is the appropriate response.
- Explain why it is required to encrypt the passwords on the router and write down the appropriate command to encrypt all the passwords on the router.When using IPsec, each computer needs its own private keys, but it's not apparent how this can be guaranteed.It is necessary to include a record of the port numbers utilised for FTP. Is it accurate to state that FTP purportedly transmits control information "out of band"?
- How much space does a MAC attacker have to tamper with the Tag (the MAC) and encrypted data? This attack fails because the receiver can always detect altered Tag/ciphertext.Which user-authentication method utilizes the TCP protocol?Explain why encrypting the passwords on the router is necessary, and write down the relevant command to encrypt all of the router's passwords.
