Tips for attending an interview in the security information sector1
1. What is cybersecurity?
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These attacks are typically designed to access, alter, or destroy sensitive information:extort money from users or interrupt normal business processes,
2. How do I defend against cyberattacks?
A successful approach to cybersecurity provides multiple layers of protection in a computer, network, program, or data to ensure security. In an organization, people, processes, and technologies must complement each other: in order to create an effective defense from a cyber attack.
3. What is the difference between closed source and open source programs?
Closed source is typically a commercially developed program. You receive an executable file that runs and does its job, but cannot be viewed remotely. However, open source provides the source code with the ability to inspect everything it does, and to make changes and recompile the code yourself.
4. Which is better?
Both have arguments for and against them, mostly related to auditing and accountability. Closed source advocates claim that open source causes problems because everyone can see exactly how it works and exploit weaknesses in the program. Open-source counters say that because closed-source programs teach that there is a way to provide complete inspection of them, it is difficult to find and fix problems in the program beyond a certain level.
5. What is SSL?
SSI. is a standard security technology used to create an encrypted link between a server and a client (usually a Web server and a Web browser).
6. What is the difference between a threat, a vulnerability, and a risk?
Threat-anything that can be exploited, intentionally or unintentionally, to gain access to, disrupt, or destroy assets. We are working to protect against threats.
Vulnerability-A weakness or gap in a security program that can be exploited by a threat to gain unauthorized access to an asset. A vulnerability is a weakness or gap in our protection efforts.
Risk-The likelihood that a threat that exploits a vulnerability will result in the loss, damage, or destruction of an asset cloud. Risk is the intersection of threat and vulnerability.
7. How do you report risk?
Risks can be reported, but they need to be assessed first. Risk assessment can be done in two ways: quantitative analysis and qualitative analysis. This approach will cater to both technical and business people. Business people will be able to see the possible numerical losses, while technical people will see the impact and frequency. Depending on the audience, risks can be assessed and reported.
8. What is a firewall?
A firewall is a part of a computer system or network designed to block unauthorized access while allowing outbound communication.
9. What is CSS (CrossSiteScripting)?
Cross-Site Scripting is usually folded into an injection attack from client-side code, where the attacker has all the permissions to execute the script in a malicious, web application or legitimate website. It is common to see this type of attack where the web application utilizes non-coded or unvalidated input from the user within the generated output.
10. Why is SSL not enough for encryption?
SSL is authentication, not hard data encryption. Its purpose is to be able to prove that the person you're talking to on the other end is who they say they are.SSL. and TLS are used almost exclusively online, but the problem is because it's a giant target that is attacked primarily through its implementation and its known methods. As a result, it is possible to strip SSL in some cases, so additional protection of data in transit and data at rest is a very good idea.
11. Between SSL and HTTPS, is it more secure?
SSL (Secure Sockets Layer) is a protocol that enables secure conversations between two or more parties over the Internet. HTTPS (HyperText Transfer Protocol Secure) is a combination of HITP and SSL that provides a more secure, encrypted browsing experience.
12. What is the difference between encryption and hashing?
Encryption is reversible, while hashing is irreversible. Hashing can be broken using rainbow tables, but it is not reversible. Encryption ensures confidentiality while hashing ensures integrity.
13. What is the difference between symmetric and asymmetric encryption
Symmetric encryption uses the same key for encryption and decryption, while asymmetric encryption uses different keys for encryption and decryption. Symmetric is usually much faster, but the key needs to be transmitted over an unencrypted channel. On the other hand, asymmetric is more secure but slower. Therefore, a hybrid method should be preferred. Use asymmetric encryption to set up the channel and then use the symmetric process to send the data.
14. What is the difference between UDP and TCP?
Both are protocols that send packets of information over the Internet and are built on top of the Internet Protocol.TCP stands for Transmission Control Protocol and is more commonly used. It numbers the packets it sends to ensure that the recipient receives them.UDP stands for User Datagram Protocol. Although it operates like TCP, it does not use TCP's checking feature, which speeds up the process but reduces its reliability.
15. What is the difference between black hat and white hat?
Black hat hackers, or simply "black hats," are the type of hackers that get attention in the popular media. Black hat hackers violate computer security for personal gain (e.g., stealing credit card numbers or obtaining personal data to sell to identity thieves) or for purely malicious purposes (e.g., creating botnets and using them to conduct DDOS attacks on websites they don't like).
White hat hackers are the opposite of black hat hackers. They are experts in "ethical hacking" of compromised computer security systems, and they use their abilities for good, ethical, and legal purposes, not bad, unethical, and criminal ones.
Tips for Attending a Security Information Sector Interview 2Essential Tips for Attending a Security Information Sector Interview
Due to the increasing number of qualified information security professionals, interviews are becoming increasingly competitive. For this reason, one's interview performance will ultimately determine the outcome. Overestimating your interviewing skills, or underestimating your competitors, can lead to a disaster, but proper preparation determines the two different outcomes of hiring and not hiring. Before you dive headfirst into interviews for information security positions, here's some guidance on how to better prepare for those interviews.
Know what information security issues are threatening the company. When a company decides to add information security staff, it may be because it finds its current workforce understaffed, or it's facing a brand-new business challenge that requires a certain level of expertise to tackle. Figuring out why the company is hiring before the interview allows the candidate to demonstrate experience that fits the employer's field.
Often times, this information can be determined by researching information security issues in the potential employer's industry. For example, a retailer may be concerned about data security standards in the payment card industry, a health care organization must be concerned about HIPAA and protecting medical records, and a technology company needs expertise in secure software development. It's also a good idea to read recent news about the company, or even its annual report released to investors, to glean events that emphasize information security-related issues. Even corporate marketing brochures can be helpful in determining how security is used as a selling point....
Use the job description as a guide, but don't take it as truth. Probably the most important thing a candidate needs to know before an interview for an information security position is the job description. Job descriptions are great for providing guidelines to candidates, but they often fail to convey what employers are really looking for. There are many reasons why it's a big mistake to prepare for an interview by using the information security job description as the sole criterion.
First, it is not clear who wrote the job description. Many times, job descriptions are roughly sketched by the hiring manager and written by the HR person. As in many exchanges, some elements are "lost in translation". As a result, the information in the job description can sometimes be misleading, causing candidates to emphasize information security skills that are less relevant to the interviewing team. Additionally, relying on job descriptions often inadvertently constrains candidate preparation, thereby limiting the information security topics mentioned in the descriptions. Since job descriptions tend to change over time, the current job description may be outdated and the need for information security skills has changed.
Finally, job descriptions generally list the information security skills that are needed, but they don't help the interviewer in terms of company culture. Often times, when candidates are interviewed according to the job description, their responses seem scripted and mechanical, and they fail to demonstrate their passion. Passion is seen as a necessity for most information security leadership roles.
Get to know the person interviewing you. When interviewing for an information security leadership position, the panel conducting the interviews is likely to consist of many different board members. These interviews are looking for candidates who can make their jobs easier. Understanding how information security relates to their specific area of expertise and how experience as an information security professional can help solve their particular problems will be a deciding factor in being recognized by them. Prior to the interview, it is important that candidates should know as much as possible about the interviewer and their role.
First, pick up an interview schedule before the interview, which is usually provided by human resources or a recruiter. Use the interview scheduler to learn the interviewer's title and try to determine how you will stand to interact with them in the information security role you are applying for. It's also a good idea to do a Google search on the interviewer or check out their resume. Doing this homework will help to get some information about things like their background, interests, and time spent at the company. Overall, all of this information will benefit you in better answering the questions they ask during the interview, and it will also allow you to relate your experience in information security more closely to their specific needs.
Review the specialized skills listed on your resume. During the interview process, the interviewer will test the technical aspects of the interviewee's information security knowledge. Most likely, the interviewer will refer to the candidate's resume and quiz him or her on technical issues related to the skills listed on the resume. In general, if specialized skills are listed on the resume, they tend to be the focus of the interviewer's questions. Before attending an interview for an information security position, make sure you have reviewed your resume and are prepared to answer questions about the specialized skills listed on the top of your resume. If you can find past technical manuals and study guides, it never hurts to review them on an ad hoc basis before the interview.
In general, the interview process is stressful. Preparing well for the interview and following the advice listed above can help you stay calm and give you extra confidence. Displaying confidence allows the interviewer to focus better and make a favorable impression, which increases the likelihood of making it to the next exciting stage.
Tips for Attending an Interview in the Security Information Sector 31. What is salted hashing?
A salt is, at its most basic level, random data. When a properly protected cryptosystem receives a new password, it creates a hash value for that password, creates a new random salt value, and then stores that combined value in its database. This helps protect against dictionary attacks and known hash attacks. For example, if a user uses a password that is similar on two different systems, the user may end up with the same hash value if they use the same hashing algorithm. However, even if one system uses *** the same hashed salt, the values will be different.
2. What is data protection in transit vs. data protection at rest
When data is protected only in the database or on the hard disk, it can be considered at rest. On the other hand, it is in transit from the server to the client. Many servers perform one or more protected SQL databases, V P N connections, etc., but not many servers perform both tasks at the same time, mainly due to the additional consumption of resources. However, both are a good practice, even if it takes longer.
3. What is the difference between a vulnerability and an exploit?
A vulnerability is a flaw in a system, or in some software on a system, that provides an attacker with a way to bypass the security infrastructure of the host operating system or the software itself. It is not an open door, but rather a weakness that can provide a way to exploit if attacked.
Exploitation is the act of trying to turn a vulnerability (weakness) into an actual way to compromise a system. Thus, a vulnerability can be exploited to turn it into a viable way to attack a system.
4. Information assurance sounds like protecting information through the use of encryption, security software, and other methods to keep it safe. On the other hand, information assurance is more related to maintaining the reliability of data a RAID configuration, backups, non-repudiation techniques, and so on.
5. What is exfiltration?
Infiltration is how you import or smuggle elements into a location. Exfiltration is the opposite: taking sensitive information or objects from a location without being detected. In a high-security environment, this can be very difficult, but not impossible.
6. What is chain of custody?
Chain of custody refers to the chronological arrangement of documents and or written records showing the seizure, custody, control, and transfer. Analyze and dispose of evidence, whether physical or electronic.
7. Configure the network to allow only . What is an easy way to configure a network to allow only one computer to log in on a particular jack?
Sticky ports are one of a network administrator's best friends and one of the biggest headaches. They allow you to set up your network so that each port on a switch allows only one (or a number you specify) computer to connect to that port by locking to a specific MAC address. If any other computer plugs into that port, the port will shut down and you will receive a call that they can no longer connect to. If you're the one running all the network connections in the first place, then this isn't a big problem, and again, if it's in a predictable pattern, then it's not a problem. But if you're working on a manual network where confusion is the norm, then you may end up spending some time trying to figure out exactly what they're connecting to.
8. What is a traceroute?
A traceroute or tracert helps you see where communication failures occur. It shows the routers that were touched when you moved to your final destination. If a place is unreachable, you can see where it happened.
9. What is the difference between software testing and penetration testing?
Software testing focuses on the functionality of the software and not the security aspects. Penetration testing will help to identify and address security vulnerabilities.
10. Use the appropriate available sanitizers to prevent cross-site scripting attacks. web developers must be concerned about the gateways through which they receive information, which must act as a barrier to malicious files. Some software or applications can be used to perform this, such as XSSMe for firefox and DomSnitch for Google Chrome.
11. Saling is the process of extending the length of a password by using certain special characters:
12. What is the use of Salting?
If you are someone who is prone to using simple or common words as passwords, salting can make your passwords stronger and less likely to be cracked.
13. What is a security misconfiguration?
A security misconfiguration is when a vulnerable device/application/network is configured in a way that can be exploited by an attacker to take advantage of it. This can be as simple as leaving the default username/password unchanged or being too simple for device accounts etc etc.
14. What is the difference between a VA and a PT?
Vulnerability assessment is a methodology used to find vulnerabilities in an application/network whereas penetration testing is the practice of discovering attackable vulnerabilities, just like what point-positive attackers do. a VA is like traveling on the ground whereas a PT is digging for its gold.
