Differentiate Between Vpn And Vlan
Companies use VLANs to consolidate devices that are dispersed across several remote sites into a single broadcast domain. VPNs, on the other hand, are used to transmit secure data between two offices of the same organization or between offices of different companies. Individuals also use it for their personal needs.A VLAN is a VPN subtype. VPN stands for Virtual Private Network, and it is a technology that creates a virtual tunnel for secure data transfer over the Internet.Because it enables encryption and anonymization, a VPN is a more advanced but more expensive solution. A VLAN is useful for segmenting a network into logical sections for easier management, but it lacks the security characteristics of a VPN.A virtual local area network minimizes the number of routers required as well as the cost of deploying routers. A VPN improves a network’s overall efficiency.Example of a VPN:- NordVPN, ZenMate
Tip #: If You Havent Heard Anything After 10 Days Follow Up With An Email Asking About The Status
If youre interested in the position and you havent heard anything, its okay to follow up after a few weeks, unless they told you the process would take longer. When you do follow up, be sure to add in that you are still very interested in the position and that you are willing to answer any additional questions they may have.
Which Is More Reliable: Ssl Or Https
SSL is a secure technology that allows two or more parties to communicate securely over the internet. To provide security, it works on top of HTTP. It works at the Presentation layer.HTTPS is a combination of HTTP and SSL that uses encryption to create a more secure surfing experience. The working of HTTPS involves the top 4 layers of the OSI model, i.e, Application Layer, Presentation Layer, Session Layer, and Transport Layer.SSL is more secure than HTTPS in terms of security.

Tip #: Do Extensive Research On The Company
This next step is critical, and the fact that it is overlooked so often is amazing. I cant even begin to tell you how many potential employees Ive interviewed who had done no research on our organization. They had no knowledge about what we did, how long we have been established or who are leadership was. On the other hand, the interviewees that came into an interview having done prior research were always impressive.
Once you are contacted to schedule an interview, begin working on researching the company in detail. Review every page of their website and complete a Google search on the company and any employees that you know or can find out about. You really can learn a great deal by doing basic internet research. I have seen examples where people have uncovered that a business is filing for bankruptcy or has been fined or sued, or that they have a long list of disgruntled former employees. While searching, try to learn about their product or service, how large of an employer they are, and how the are marketing themselves.
Drive by or visit the organization during the workday to see where they are located and how busy the facility is during normal work hours. You may find that their building is in a bad location, or that there is no parking, or that they are busy with activity. Having scoped out where they are located and how to get there will also make you feel more comfortable when you do go in for your interview.
What Is A Cia Triad
CIA triad is a model designed to handle policies for information security within an organization.
- Confidentiality – A collection of rules that limits access to information.
- Integrity – It assures the information is trustworthy and reliable.
- Availability – It provides reliable access to data for authorized people.
What Are Salted Hashes
Salt is a random data. When a properly protected password system receives a new password, it creates a hash value of that password, a random salt value, and then the combined value is stored in its database. This helps to defend against dictionary attacks and known hash attacks.
Example: If someone uses the same password on two different systems and they are being used using the same hashing algorithm, the hash value would be same, however, if even one of the system uses salt with the hashes, the value will be different.
Security Guard Interview Questions And Answers

What To Expect From A Cybersecurity Interview
Expect to be asked questions about:
Shine a light on your soft skills, these are just as important as your hard skills. Hard skills can after all be taught being a team player or being able to think outside of the box, for example, are far harder to learn.
And even more importantly, you have to be able to communicate effectively. You could be at the top of your game, the best cybersecurity professional for 50 years, but if you cant articulate yourself or play well with others, you wont get the job.
- Your qualifications.
Are you qualified for the job?
- Your understanding of the company.
Do your homework and show willing dont embarrass yourself by asking what the company does.
Youre here because you want to work for them how unmotivated are you going to come across if you dont know who they are? At the very least know what the company is doing with regards compliance or information security, and visualise how you would fit into that.
Also look on their website and get a feel for their language and use it during the interview. The more you look like a cultural fit, the more you will appeal to them.
- Your understanding about the role youre interviewing for.
You want to align yourself with the ideal candidate that the interviewers have in their head. The more boxes you can tick to show you are capable of carrying out the role effectively, is going to work in your favour.
- Your motivations to join their team.
- That assess your cybersecurity technical skills.
Differentiate Between Threat Vulnerability And Risk
Threat: A threat is any form of hazard that has the potential to destroy or steal data, disrupt operations, or cause harm in general. Malware, phishing, data breaches, and even unethical employees are all examples of threats.Threat actors, who might be individuals or groups with a variety of backgrounds and motives, express threats. Understanding threats is essential for developing effective mitigations and making informed cybersecurity decisions. Threat intelligence is information regarding threats and threat actors.
Vulnerability: A vulnerability is a flaw in hardware, software, personnel, or procedures that threat actors can use to achieve their objectives.Physical vulnerabilities, such as publicly exposed networking equipment, software vulnerabilities, such as a buffer overflow vulnerability in a browser, and even human vulnerabilities, such as an employee vulnerable to phishing assaults, are all examples of vulnerabilities.Vulnerability management is the process of identifying, reporting and repairing vulnerabilities. A zero-day vulnerability is a vulnerability for which a remedy is not yet available.
Risk: The probability of a threat and the consequence of a vulnerability are combined to form risk. To put it another way, the risk is the likelihood of a threat agent successfully exploiting a vulnerability, which may be calculated using the formula:
Risk = Likelihood of a threat * Vulnerability Impact
Contact The Key Players
As a cybersecurity manager, you need to contact key players in the company and familiarise yourself with their units and what they do. For instance, you could go to customer service and ask to go through their induction training. A couple of hours spent immersed in the customer service world will reveal an incredible amount about the people, processes, and tools involved. Youll get firsthand experience, and the customer service manager will appreciate your interest.
After this, the cybersecurity manager should schedule meetings with key stakeholders to talk about the cyber risks involved in different areas of the company. The cybersecurity managers goal should be to help the managers and department heads understand the cybersecurity risks to their department and then convince those leaders to request the budget funds required to address the risks. Turning key decision makers into champions for cybersecurity is one of the most effective strategies for acquiring the resources needed.

Whats The Difference Between Symmetric And Asymmetric Encryption And Which Is Better
This is a vast topic so keep your answer simple and direct
Example:Symmetric encryption uses the same key for encryption and decryption. Asymmetric encryption, on the other hand, uses different keys. Symmetric is usually faster but the key must be transferred over an unencrypted channel. Asymmetric is more secure but its slower. The best approach would combine the two, setting up a channel using asymmetric encryption and then sending the data using a symmetric process.

What Are The Different Layers Of The Osi Model
An OSI model is a reference model for how applications communicate over a network. The purpose of an OSI reference is to guide vendors and developers so the digital communication products and software programs can interoperate.
Following are the OSI layers:
Physical Layer: Responsible for transmission of digital data from sender to receiver through the communication media,
Data Link Layer: Handles the movement of data to and from the physical link. It is also responsible for encoding and decoding of data bits.
Network Layer: Responsible for packet forwarding and providing routing paths for network communication.
Transport Layer: Responsible for end-to-end communication over the network. It splits the data from the above layer and passes it to the Network Layer and then ensures that all the data has successfully reached at the receivers end.
Session Layer: Controls connection between the sender and the receiver. It is responsible for starting, ending, and managing the session and establishing, maintaining and synchronizing interaction between the sender and the receiver.
Presentation Layer: It deals with presenting the data in a proper format and data structure instead of sending raw datagrams or packets.
Application Layer: It provides an interface between the application and the network. It focuses on process-to-process communication and provides a communication interface.
List Of Cybersecurity Interview Questions: Technical Questions

Common Cybersecurity Interview Questions You Should Prepare To Ask
– We all know that you should be prepared to ask questions during your interview, but what kind of questions are most effective? There are three categories of interview questions, corporate, management, and job function. You want to ask all the questions within one category before moving on to another. For instance, try to ask all the questions about the organization one after the other. Then once you’re done ask all the questions related to management and so on. This is so that you appear organized and not simply asking random questions for the sake of asking questions. This also helps the interviewer to answer your questions with a consistent line of thought. Trust me, jumping randomly from one category to the next will be very noticeable, and frustrating for your interviewer. Keep in mind that all questions are not for every interviewer. You want to keep your questions audience appropriate depending on
