CISSP Interview Questions

CISSP Interview Question and Answers

The CISSP managerial certification calls for at least 5 years of practical expertise in 2 of the 8 security domains. It is a prestigious credential, the knowledge of which is highly valued as well as its practical application.

Hence, if you want to ace the CISSP interview then knowledge and preparation are what you need the most. We bring to you the best CISSP interview questions and answers to win it.

Q1) Explain threat, risk, and vulnerability with reference to cybersecurity.

Ans: A system's safety measures have some degree of vulnerability (weakness), and a threat is an attacker who takes advantage of that weakness. Risk measures the likelihood of loss when the threat takes advantage of the vulnerability. For instance, a detractor can easily break into a server using the regular username and password and arbitrarily control it.

Q2) What elements raise the security risks?

Ans: Although there is no clear-cut solution to this question, it demonstrates your focus and assurance in the interviewer. You can respond that one of the main contributing factors is a lack of a highly qualified executive team or funding for security software. Or perhaps there is a lack of commitment on the side of workers who do not follow the finest security procedures.

Q3) How should risks be reported?

Ans: It is necessary to assess the risk first before reporting it. There are two methods for doing that: quantitative analysis and qualitative analysis. Both technical and commercial professionals profit from this approach. Businesspeople can calculate future losses in numbers when technical experts can identify the frequency and impact. The audience reported that the risk was afterward evaluated and disclosed.

Q4) Specify which processes will be used in the strategy implementation to increase security.

Ans: Forms are made available to developers to make it easier for them to document the systems where changes happened during the implementation process and to track and detect any change that occurs.

Q5) Describe the analysis and monitoring of network traffic.

Ans: Network traffic monitoring, which is comparable to network traffic analysis, is a security logical tool used by administrators of computer systems to identify security flaws that could compromise network traffic monitoring, functionality, and accessibility.

Q6) What does Defense in depth entail?

Ans: Network traffic monitoring, which is comparable to network traffic analysis, is a security logical tool used by admins of computer systems to identify security flaws that could compromise network traffic monitoring, performance, and exposure.

Q7) Which type of access control permits a group of users to use a resource?

Ans: Users are categorized by roles in access control systems. The network's designated locations were then assigned these roles. This makes it simpler to find users who accessed resources.

Q8) Describe a denial-of-service attack.

Ans: It is a program that floods another network with a large number of packets in an effort to deplete its resources, disable it, and make it unusable.

Q9) Why were suppliers or subcontractors considered dangerous?

Ans: Without enough training and supervision, vendors frequently have extensive access to the organization's systems. In general, there is no plan for finishing a contract. Data is transferred by email, where the risks of viruses and other malware were significant, and vendors also work from home, offer cloud services, etc. Companies also infrequently verify the security of data that has been safely removed from vendor assets once projects are completed.

Q10) When does a person become a risk to information security?

Ans. People who are frequently referred to as "insider" hazards. When they unintentionally or actively engage in a way that puts them at risk for information security, either vendors or employees become potential security risks. For instance, misplacing organizational resources, casually discussing clients with outsiders, etc.

Q11) Compare and contrast RSA with Diffie-Hellman.

Ans: Diffie-hellman is a key-exchange protocol, whereas RSA is a signing system. The main distinction between the two is that whereas Diffie-Hellman doesn't require you to memorize any key information in advance, RSA does. Organizations do not want to see blank faces.

Q12) How significant are tools in an organization? What should one do if a tool breaks down?

Ans: A company shouldn't rely just on its tools. Tools are frequently used for two purposes: first, to complete tasks that cannot be completed manually, like antivirus. The second is to finish a time-sensitive operation, like installing a firewall, on schedule. We require a tool to speed up the tasks, which is the third reason. The staff should make sure that they are sufficiently knowledgeable about the tools and how they operate. 

Now, when a tool breaks down, we can figure out what could have gone wrong. It's risky to rely too heavily on the technologies, thus backup strategies or alternate ways need to be in place. If there is a third party involved, it is feasible to do the necessary maintenance and audits. For proper operation, hardware and software cleanliness must be upheld.

Q13) How can remote workers' connections to the office network be secured?

Ans: The staff members can use a VPN service. With the use of a virtual private network, or VPN, customers can create a tunnel from an unstable network to the office network. Other security tools, such as firewalls and access controls, are still necessary. Two-factor authentication is required for a VPN service to improve the security architecture.

Q14) What is the best strategy to guarantee connectivity between the headquarters and the ten office locations?

Ans: The offices could be linked in a number of different ways. One method is to connect utilizing ten T1 connections that run from various sites to the main office. The second method might involve MPLS connections between the offices. The best option is to use MPLS rather than T1 lines because T1 requires 10 different T1 handling circuits at the headquarters, whereas MPLS does not.

Q15) What exactly is a phishing scam?

Ans: A phishing assault is a sort of social engineering in which individuals are persuaded to divulge private information by opening phony email attachments or links. Malware is dispersed by this attack, and networks are also compromised.

Q16) How can you tell if someone has accessed the network without an authorization?

Ans: Proper log monitoring is necessary to make sure that no evidence of unauthorized access exists. In order to notify users whether a login attempt succeeds or fails, servers might be configured to do so. Any unwanted access will be found and dealt with as soon as possible thanks to a diligent monitoring program.

Q17) How crucial is internet security for a business?

Ans: The Internet cannot be opened like a freeway since it is the untrusted portion of the network. While limiting internet access could be a solution, the majority of businesses rely on it for their daily operations. Internet access should be limited in accordance with corporate policies. Access to some websites may be restricted, for example, by restricting the upload feature to stop data leaks. To make sure that the internet is used responsibly and not for selfish gains—such as downloading movies or other content—internet records might be monitored.

Q18) How many different kinds of firewalls are there, and what makes each one unique?

Ans: A network firewall and a web application firewall are the two types of firewalls from an organizational perspective. While a web application can filter layer 7 traffic and defend against web application attacks, a network firewall can only give security against layer 3 attacks.
