Answer:

a) Viruses

Explanation:

Vulnerability assessment is performed by variety of tools and these can be protocol analyzer, vulnerability scanner, Honeypots, port scanners, honey nets and banner grabbing tools.

Port scanners : they are used to scan the ports which can be exploited by attackers. Most of TCP/IP applications communicate using different ports and attackers can exploit these ports if they are found vulnerable. for example : ports like 80 and 443 are commonly used for HTTP and SSL communication. 22 is used for SSH and if they are open to world then it will allow attackers to use those to get the entry into the system.

Protocol Analyzers : They are used to analyze the packet captures. tools like wireshark, tshark, these tools will help user to decode HTTP/SSL/HTTPS/FTP/RSTP or any application protocols communication. this will help user to understand any unwanted or non-anticipated traffic.

Vulnerability Scanners : They are used to detect the vulnerabilities in the network or systems. these will help administrators to get the alerts whenever there are unanticipated activity. It will have two types of scanners one is active scanner and other is passive scanner. Active scanners will keep on sending probes at the fixed time slots and passibe scanners will be in listening mode all the time. These scanners will alert when a new nodes comes up or goes down or if any system gets compromised.

Honeypots and Honey nets : They are devices or softwares which are having limited security. These devices are made vulnerable purposefully so that attackers can try and attack. This will help softwares to detect the attackers when they try to exploit these open vulnerabilities. They are deceptions created with purpose.

Banner grabbing Tools : These are tools which will capture the banner information like HTTP protocol version, underlying operating system, open ssl versions being used, server software and similar information. these are important as it will open up potential vulnerabilities in the underlying software. for ex : SSLv3 has a vulnerability known to world and can be exploited by anyone.

One foot equals 12 inches. Write a function named feet_to_inches that accepts a number of feet as an argument and returns the nu

fenix001 [56]

Answer:

def feet_to_inches( feet ):

inches = feet * 12

print(inches, "inches")

feet_to_inches(10)

Explanation:

The code is written in python. The unit for conversion base on your question is that 1 ft = 12 inches. Therefore,

def feet_to_inches( feet ):

This code we define a function and pass the argument as feet which is the length in ft that is required when we call the function.

inches = feet * 12

Here the length in ft is been converted to inches by multiplying by 12.

print(inches, "inches")

Here we print the value in inches .

feet_to_inches(10)

Here we call the function and pass the argument in feet to be converted

Explanation:

PGP encryption from the command line can be done using the following format:

pgp --encrypt (input) --recipient (user) --output (output file)

Therefore, PGP command line syntax to encrypt the my-message.txt file for a specific user (Sean) and save the output as secret-message.txt.gpg is:

g 1-1 Which network model layer provides information about the physical dimensions of a network connector like an RJ45

Harlamova29_29 [7]

Answer:

Physical layer

Explanation:

OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;

1. Physical Layer

2. Data link Layer

3. Network Layer

4. Transport Layer

5. Session Layer

6. Presentation Layer

7. Application Layer

Each layer has its unique functionality which is responsible for the proper functioning of the communication services.

In the OSI model, the physical layer is the first and lowest layer. Just like its name physical, it addresses and provides information about the physical characteristics such as type of connector, cable type, length of cable, etc., of a network.

This ultimately implies that, the physical layer of the network (OSI) model layer provides information about the physical dimensions of a network connector such as a RJ45. A RJ45 is used for connecting a CAT-5 or CAT-6 cable to a networking device.
