Questions for network-related examinations can get rather complex. It isn’t only what they ask, but also how they ask them, so questions can leave you scratching your head.
Two of the most common questions that often catch people out are, What can be deployed to intercept and log network traffic passing through the network? What attack involves impersonating another device?
Much of what they ask relate to network intrusions, and it can be hard a subject to study at home. Packet sniffers are frequently discussed as they connect to networks and often come with a technical language; thus, it takes an expert to understand all this.
In our guide, we look closer at these questions to try to make them easier to understand. Once you have studied them, you may be ready to move on to another question that doesn’t tap into your mind and intercept your study as much. (Read What Is The Meaning Of Bandwidth In Network)
Common Question About Protocol Analyzers, Packet Sniffers, and More
Here are a few questions that can often catch you out. We will answer and explain where possible about such network vulnerabilities.
What can be deployed to intercept and log network traffic passing through the network?
Network Event viewers, NIDSs, Protocol analyzers, Proxy catchers, NIPSs
The answer here can be tricky as Network Event viewers, NIDSs, Protocol analyzers, Proxy catchers, NIPSs appear to be the same.
However, the correct answer is that “Packet sniffers” are protocol analyzers, which can be deployed to intercept and log network traffic passing through the network.
Packet sniffers intercept traffic and data as it passes across a wired or wireless network (Wi-Fi) and copies the contents to a file. (Read Hypixel Ban List)
While the answer shows software that can be useful in building efficient networks, hackers can use them when they connect to networks.
Hackers can collect passwords, browse networks for unencrypted data that passes inside unprotected packets, and intercepting network traffic as it is in transit. An expert hacker can use packet sniffers should they wish to carry out man-in-the-middle attacks.
A network interface card (NIC) has to be set to promiscuous mode to install packet sniffing software.
You can protect yourself against Network Event viewers, NIDSs, Protocol analyzers, Proxy catchers, NIPSs, and other hacking threats to use a VPN (Virtual Private Network).
All data passes encrypted, and no matter what Protocol analyzers, packet sniffers, proxy catchers, Nipss a hacker uses, there is little chance they can read what the data packets contain. (Read What Is The Most Common Network Topology)
Candidate for Tricky Network Related Question
Here is another question where the answer is a term rather than a full sentence to the question. Any expert would know this term and many others. You may find a question of this type easier to remember the answer.
What attack involves impersonating another device?
Spimming, Pharming, Spoofing, Spearing, Phishing
Again, at first glance, a user can be confused with the “what attack involves impersonating another device” because many of these appear to be the same thing.
However, once you understand the differences, it is a bit easier to remember, and you can confidently click on the right answer.
Spimming is instant messaging, so unrelated to a network question. Now you are down to four possible answers. Pharming, Spoofing, Spearing, Phishing is the four.
Pharming is a sort of fraud involving malicious code, and phishing is a type of social engineering attack often used to steal user data. Spearing is like a targeted email to a single person.
Out of spearing phishing, pharming, spoofing involves impersonating another device or user for launching an attack. A popular way to do this is by creating IP packets using someone else’s IP address.
It is straightforward to answer any question, like “what attack involves impersonating another device?” once you rule out a term or sign if you see they are not related.
Narrow down the incorrect term to leave yourself with a chance to achieve a correct guess if you don’t know.
Alternative Network Questions to Browse
Here are another couple of questions to tackle your resources that you’ll find with the questions above.
Packet sniffing can be helpful to detect rogues?
Packet sniffers are protocol analyzers and deployed to intercept and log network traffic passing through the network. Thus, it can be technically possible to spot rogues using your protocol analyzers, proxy catchers, Nipss, and wireless sniffing tools.
Which of the following is NOT a means used by an attacker to do reconnaissance on a network?
Smurf attack, Port scan attack, DNS footprinting, Christmas tree attack, TCP/IP Stack fingerprinting, Banner grabbing.
Out of each question here, this could be the most challenging to those unfamiliar with the term. When you find the answer, it is something you’ll never forget. Which of the following is NOT a means used by an attacker to do reconnaissance on a network answer is a Smurf Attack.
A Smurf attack is a distributed denial-of-service (DDoS) attack. With this, an attacker tries to flood a server with Internet Control Message Protocol (ICMP) packets.
Much of the above questions are all about knowing certain terms before you can get the right answer. The first and second could be understood better if you were in a lab environment.
While they are good resources, and you can see how they benefit in finding potential issues or hackers on your network, it doesn’t do anything to stop a hacker who can tap into your packets.
VPNs are the best way to provide security to data. They can make it more of a challenge to find your network; since your IP address is changed, they can still find it, especially if anyone uses HTTP traffic rather than HTTPS.
VPNs offer full data encryption and work with a single click of an icon, or you can add these to a router to secure your entire network with unlimited devices.
