1.

Some people work best as part of a group - others prefer the role of individual contributor. How would you describe yourself?

The purpose of this question is to discover your collaboration skills. There are benefits to both working by yourself and functioning as a member of a team. You should be able to discuss both of these, their benefits, and challenges. You then complete your answer by describing which one you prefer and why you like to work in this manner.

William's Answer

"I am able to work both as an individual contributor or as a member of a highly functional team. The benefit of working as an individual is that you move faster and can complete a project in less time. However, you are also limited to your ideas, experience, and skills. As a member of a team, you move slower due to the need to collaborate and discuss actions and topics related to the project you're working on. However, the benefit is that many individuals contribute to the project, each providing a unique set of experiences, skills, and talents. The output of a team often eclipses the data and up to that of an individual contributor. Given a choice, I would rather function as a member of a team."

2.

What is traceroute, and how is it used?

Yet another technical question. As stated earlier, most of the questions you will be asked during an interview will be technical questions. The best way to prepare for these is to review the terminology, processes, and procedures you use as an information security analyst. You should also spend time practicing these questions, reading both the question and the answer out loud. You can then formulate your own answer to the question. The three keys to a successful interview include research, preparation, and practice.

William's Answer

"Traceroute is a process used by a systems analyst to uncover any breakdowns or gaps in communications and pinpoint where they are occurring in the network. This technique follows the data and the route it takes, identifying the network devices along its path. Once you've identified where the connection break has occurred, you can repair it with either software or hardware."

3.

Tell me about an important goal that you set in the past. Were you successful?

By asking this question, the interviewer is collecting two pieces of information. The first is whether you are goal-oriented and are willing to set ambitious objectives. The second is whether you were able to achieve them and how you did it. While preparing for an interview, you should have a list of significant achievements you've made in past positions and a brief description of how you accomplished them. Successful interviews are a result of research, preparation, and practice.

William's Answer

"In one of my former positions, I set a goal for our team for 90 days of continual network uptime. This required tha there were no security intrusions to the network during this period. The team achieved this objective by first profiling the network and identifying any vulnerabilities. We then implemented patches and fixes to address these. Once this was completed, the clock started. The network actually stayed up and had zero intrusions for over 120 days. I reward my team by taking them on an exciting team-building event and providing them each with a bonus check."

4.

What are UDP and TCP, and how do they differ?

While interviewing for the role of an information security analyst, you are going to be asked multiple technical questions. You can easily prepare for this by reviewing the terminology, acronyms, and jargon used in this profession. Another way to prepare is to study these questions, reading both the question and the answer aloud. This trains your brain to be ready to answer the questions appropriately.

William's Answer

"Both UDP and TCP are protocols used to move data across the Internet. UDP stands for user datagram protocol. TCP stands for transmission control protocol. Of these two, TCP is the mos common protocol used. It numbers each packet when transmitted to verify that all the packets have been received, thus providing high reliability. UDP does not have this error-checking capability."

5.

Tell me about a time when you and your previous supervisor disagreed, but you still found a way to get your point across.

This is another example of a behavioral question. As a reminder, behavioral questions ask you to respond to a situation that is likely to occur if you are hired for the position for which you are interviewing. Remember to use the STAR framework when answering behavioral questions. Keep your answers brief and to the point, and anticipate a follow-up question.

William's Answer

"It is not often that my management team and I have disagreements, but it does happen. In my most recent role, there was a situation involving my recommendation to upgrade the security of our network. Management felt that it was too expensive, and the predicted results could not be cost-justified. I knew I had to convince them to do the upgrade, or our network would be at risk. I collected information about similar threats to other networks and the costs of resolving issues caused by attacks on the network. It became obvious that it would be easier to implement my suggestions than to remediate the situation after an attack occurred. Management agreed with my suggestion, and we implemented the upgrade in less time and at a lower cost than I had originally predicted. To my knowledge, the network has never suffered an attack due to this solution."

6.

What methods do you use to confirm that a server is secure?

This is an example of an operational question. Interviewers ask operational questions to determine how you go about doing your job. When answering an operational question, you should be brief and to the point. The interviewer will ask you a follow-up question if they need additional information or want to explore the topic in more detail. Additionally, you can answer this question with information that aligns with the operations of the organization with which you are interviewing.

William's Answer

"When securing a server, the first thing I do is to check to see if there are any open ports. These occur when technicians are updating the server or installing new software. Once I close these, I examine the software in the patches on the server to ensure they're up to date with all the appropriate security measures. If not, I patch them to the most current level. The final thing I do is to minimize access to the server, allowing access to people who need to be able to update it or make authorized changes."

7.

When you have been made aware of, or have discovered for yourself, a problem in your work performance, what was your course of action? Can you give an example?

Being self-aware of issues that impede your work performance and correcting them is a characteristic that employers look for in candidates they are interviewing. Many people become defensive when asked a question like this, claiming that they do not have any issues that impact their work. This is the wrong approach. Since the question asks for an example, you should discuss a minor issue that may have impacted your performance and how you resolved it. Ideally, the issue should not be relevant to the position for which you are interviewing.

William's Answer

"I constantly perform self-checks to make sure there are no issues which are impacting my job. I also occasionally conduct 360 interviews with my peers, management, and the people I manage to make sure I'm doing everything right. If I do discover an issue, I take immediate action to correct it. I recently became aware of the fact that I did not return emails promptly. This was impacting people who were waiting for my response. Once I was aware of this, I created a system to prioritize my emails so I could respond to the important ones, and delay reading the less critical emails."

8.

Can you think of a situation where innovation was required at work? What did you do in this situation?

This question is similar to 'Give an example of a problem that you faced on any job that you have had and tell me how you went about solving it.'. These types of questions are behavioral. They require you to discuss how you would react to a specific scenario the interviewer presents to you. Behavioral questions are best answered using the STAR framework. You state the Situation, describe the Task you needed to complete, discuss the Actions you took, and then talk about the results you achieved. Situational questions can address past actions or hypothetical situations that may occur if you are hired for this position.

William's Answer

"In one of my past positions, the department's budget was reduced due to a downturn in sales for the entire company. We were asked to do more with less and still maintain the security of the company's IT infrastructure. I met with my team, and we discussed ways we could consolidate our hardware while still providing security to the network. We were able to remove 30% of our network servers and half of the routers without impacting either the performance or the security of the network. This resulted in cost savings plus an inventory of spare parts we could use if something broke."

9.

Describe a time when you made a suggestion to improve the work in your organization.

When employers interview candidates, they're looking for somebody who can help them make money, save money, or save time. Being able to describe a situation in which you made a recommendation to improve the workflow of the organization will help you stand out amongst the other candidates. This doesn't necessarily have to be a large improvement. It can involve something minor but which helped you or other people do their jobs better. Continuous improvement as a priority with most organizations, and your ability to demonstrate experience in this area will help you during the interview.

William's Answer

"I am always looking for opportunities to reduce costs, save time, or improve processes. I recently noticed that my team was documenting their activities both in writing and with emails. This didn't make sense since very few people ever read the written reports. I created report templates which the team could use online to document their work. This not only eliminated the redundancy but allowed the team to complete the forms while waiting for other processes to run, thereby reducing the overall time to complete this task."

10.

Can you discuss the differences between a threat and a vulnerability?

Yet another technical question. While these may not seem like technical terms, used in the context of the information security analyst interview, they are. It is not uncommon for a technical question to ask you to compare two different terms. Technical questions can also ask you to define a single term. Keep in mind that you need to answer technical questions directly and briefly. You should anticipate follow-up questions.

William's Answer

"While these two terms may seem similar, there are subtle differences between them. A vulnerability defines a weakness in the organization's IT infrastructure, which can be exploited by malicious individuals. Vulnerabilities may sit dormant for long periods and go undetected until hackers use them to gain access to the network and the data contained within it. Threats, on the other hand, are active issues or incidents which are in the process of attacking an organization or working to gain access. Vulnerabilities can be addressed by constantly monitoring the network to identify them, and then addressing them with patches, software upgrades or other methods. Threats can only be resolved by creating defenses against them. This requires constant monitoring, awareness, and active remediation or the development of protections."

11.

What is your position regarding DNS monitoring? Do you feel it is important, and if so, why?

At first glance, you may believe that this is a technical question. However, if you reread the question, it asks for your opinion, not a definition or explanation. By framing the question in this manner, the interviewer is assuming you know what DNS monitoring means. This may indicate that they are considering eliminating this process from their current operations. As the interview progresses, you will gain additional insight into the organization's processes, procedures, and operations. You should already know quite a bit about this based on the research you did prior to the interview. Any time you answer a question, you should align it with the needs of the organization. This better qualifies you for the position for which you are interviewing.

Foxample: "In my opinion, DNS monitoring is critically important. While I've heard counterpoints to this position, they are typically based on the assumption that DNS monitoring indicates that domain naming services are weak. However, the monitoring requires few resources and ensures that users can access any resource available on the Internet easily. It also reduces the vulnerability of data passing through port number 53 and ensures unauthorized users do not have access to the organization's network."

William's Answer

It also reduces the vulnerability of data passing through port number 53 and ensures unauthorized users do not have access to the organization's network."

12.

Can you define symmetric and asymmetric encryption, and discuss their differences?

At this point, you can probably already recognize this as a technical question. This is obvious because it is both asking you for a definition and to discuss the differences in these terms and how they are used in your profession. Keep in mind that technical questions are best answered directly and briefly. The interviewer will ask you additional questions if they need more information or want to explore this topic in more detail. So be prepared for follow-up questions.

William's Answer

"Symmetric encryption is the process of encrypting data by creating a key which can then be used to decrypt it. In this process, a single key is used for the encryption and decryption of the data. Asymmetric encryption is similar but uses different keys for each transmission. Typically, technicians will use asymmetric encryption during the first transmission of data, followed by symmetric encryption for subsequent transmissions. Using the different types of encryption in this manner ensures that security of the data while expediting transmissions once the communication channel has been established."

13.

Is it necessary to approach cybersecurity issues differently based on whether the IT resources are in the cloud or on-premises?

Organizations have the option to manage their IT resources on their own premises, at a site hosted by a third party, or using cloud resources, such as AWS or Azure. Cybersecurity issues will differ depending on the physical location and type of resources the organization uses. In some instances, the company will use all three of these, making the cybersecurity process even more complex. You should be able to address each one of these and briefly discuss how they differ and what measures you need to take based on the location of the resources and how they are accessed.

William's Answer

"It used to be very simple to manage an organization's cybersecurity issues when everything was onsite at the company's datacenter. However, in today's environment, IT assets are spread across a variety of locations. These include the on-premise datacenter, a third-party hosted site, and in the cloud. While this helps ensure the security of the data through replication, it also presents challenges when transmitting data. Measures such as data encryption, replication, and tracerouting all help to ensure the data is secure and safe. Other techniques include strong user authentication and specific security measures built into the contracts with the third-party providers."

14.

When tasked with strengthening user authentication, what methods would you use to?

You probably already recognize this as an operational question. This is specifically asking you about the process you use to perform a task. As a reminder, operational questions should be answered directly and succinctly, and you should anticipate follow-up questions.

William's Answer

"One of the key elements of data security is user authentication. The most basic form of user authentication is supplying the user with a username and password. This is needed at any time the user logs in to the application or the network. A higher level of security is known as two-step authentication. In addition to the user ID and password, a code is sent to a device the user has pre-registered. They are then required to input the code before they are allowed to access the network."

15.

When preparing to transmit data, what would you do first, compress it, or encrypt it?

This is both a technical as well as a follow-up question. In your answer to the question 'What are the differences between encoding, encrypting, and hashing?', you discussed encryption. This technical question is asking a follow-up question about how you go about performing the encryption process. As discussed earlier, you should always anticipate follow-up questions once you've answered an inquiry from an interviewer. By keeping your previous answer brief and to the point, you encouraged the interviewer to explore this topic in more detail. Since you have expertise in this area, the questions should be easy for you to answer. This is also an example of how you can guide the interviewer through the interview.

William's Answer

"When using encryption to secure data, you should always encrypt the data before compressing it. If you compress the data first, you could not encrypt it properly or decrypt it when received by another device. The exact process is to create an encryption key, encrypt the data, compress it, then transmit the data and the decryption key to the receiving party."
