Top 50 Cyber Security Interview Questions and Answers (updated for 2018)

The list and approach has evolved over the years, as I think it should, and I think it represents a good balance between technical content and the philosophy around desired answers. How to Build a Successful Cybersecurity Career. Be willing to constantly evaluate your questions including these below to make sure they are not based on pet, gotcha, puzzle, or pressure. Have them talk through how each are used. The key sorry is that they understand the initial exchange is done using asymmetric and that bulk data encryption requires speed and therefore symmetric algorithms.

Standard stuff here: make sure they know that symmetric uses a single key while public-key uses two. Look for the standard responses, with the client sending helo with ciphers, server responding with a public key and picking a cipher, agreement on a shared key, etc.

But then dive deeper into the questions below. If they get that far, make sure they can elaborate on the actual difference, which is that one requires you to have key material beforehand RSA , while the other does not DH.

Blank stares are undesirable. Encoding is designed to protect the integrity of data as it crosses networks and systems, i. It is easily reversible because the system for encoding is almost necessarily and by definition in wide use. With hashing the operation is one-way non-reversible , and the output is of a fixed length that is usually much smaller than the input.

An IV is used to initiate encryption by providing an addition third input in addition to the cleartext and the key. In general you want IVs that are random and unpredictable, which are used only once for each message. The goal is to ensure that two messages encrypted with the same key do not result in the same ciphertext.

Block-based encryption algorithms work on a block of cleartext at a time, and are best used for situations where you know how large the message will be, e. ECB just does a one-to-one lookup for encryption, without using an IV, which makes it fairly easy to attack using a chosen-plaintext attack.

The difference in results can be remarkable. Trick question here. And the goal is not to be cute. Look for a smile like they caught you in the cookie jar. A trick question, to be sure, but an important one. If they start throwing out port numbers you may want to immediately move to the next candidate. An answer of either is a fail, as those are layer 4 protocols. Look for a discussion of security by obscurity and the pros and cons of being visible vs.

Basically anything intelligent in terms of discussion. There can be many signs of maturity or immaturity in this answer. If they get it right you can lighten up and offer extra credit for the difference between Linux and Windows versions.

Many people think that it first sends a packet to the first hop, gets a time. Then it sends a packet to the second hop, gets a time, and keeps going until it gets done. As with most of these questions, the goal is to get them talking so you can expose their knowledge, passion, or lack thereof. Look for answers around modern languages and frameworks, and built-in OS protections that exist in various operating systems. Look for biases. Does he absolutely hate Windows and refuse to work with it?

This is a sign of an immature hobbyist who will cause you problems in the future. Is he a Windows fanboy who hates Linux with a passion? If so just thank him for his time and show him out. Linux is everywhere in the security world. Other good responses include those around using solid, dependable frameworks, and not building your own.

Look for discussion of account lockouts, IP restrictions, fail2ban, commercial versions thereof, etc. Not knowing this is more forgivable than not knowing what XSS is, but only for junior positions.

A victim just loading that page could potentially get logged out from foo. Nonces required by the server for each page or each request is an accepted, albeit not foolproof, method. This is a fun one, as it requires them to set some ground rules. Not natively. Stored is on a static page or pulled from a database and displayed to the user directly.

Instead, we have a ton of unfixed things and more tests being performed. A variation of this is something like:. This is a big one. This type of response shows that the individual understands that business is there to make money, and that we are there to help them do that.

It is this sort of perspective that I think represents the highest level of security understanding—-a realization that security is there for the company and not the other way around. Knowing basics like risk, vulnerability, threat, exposure, etc. Just look for solid answers that are self-consistent.

Where is the important data? Who interacts with it? Network diagrams. Visibility touch points. Ingress and egress filtering. Previous vulnerability assessments. The key is to see that they could quickly prioritize, in just a few seconds, what would be the most important things to learn in an unknown situation.

This one is opinion-based, and we all have opinions. Focus on the quality of the argument put forth rather than whether or not they chose the same as you, necessarily. My answer to this is that vulnerabilities should usually be the main focus since we in the corporate world usually have little control over the threats. Another way to take that, however, is to say that the threats in terms of vectors will always remain the same, and that the vulnerabilities we are fixing are only the known ones.

Therefore we should be applying defense-in-depth based on threat modeling in addition to just keeping ourselves up to date. The answer to this question is often very telling about a given candidate. My main goal here is to get them to show me pros and cons for each.

The ideal answer involves the size of the project, how many developers are working on it and what their backgrounds are , and most importantly — quality control. There are many examples of horribly insecure applications that came from both camps. Look for a thorough answer regarding overall password attacks and how rainbow tables make them faster.

You purposely want to give the question without context. A standard question type. The key is how they react. Do they panic, or do they enjoy the challenge and think through it? I was asked this question during an interview at Cisco.

We want to know how much experience they have tracking the things that matter vs. Does that mean more likely to attack you, or more dangerous when they do? The questions above are fairly straightforward.

They are, generally, negative filters, i. If you are dealing with a more advanced candidate then one approach I recommend taking is that of the onion model.

The Onion Model of interviewing starts at the surface level and then dives deeper and deeper—often to a point that the candidate cannot go. One component of this cannot be overstated: Using this method allows you to dive into the onion in different ways, so even candidates who have read this list, for example, will not have perfect answers even if you ask the same question.

This is a trick question, as it can use lots of options, depending on the tool. Then you move on. And they need to consider round-trip times. A bad answer is the look of WTF on the face of the interviewee. Answers here can vary widely; you want to see them cover the basics: encryption, DNS rotation, the use of common protocols, obscuring the heartbeat, the mechanism for providing updates, etc.

Another option for going to increasing depth, is to role-play with the candidate. You present them a problem, and they have to troubleshoot. I had one of these during an interview and it was quite valuable. They are now at the client site and are free to talk to you as the client interviewing them , or to ask you as the controller of the environment, e.

Do I see any connections to IP 8. At the top tier of technical security roles you may want someone who is capable of designing as well as understanding. In these cases you can also ask questions about design flaws, how they would improve a given protocol, etc. You can ask infinite variations of these, of course. Asking for three options instead of one, or asking them to rank the results, etc.

So with all that being said, here are my current favorite questions to ask if I have limited time. For more on hiring overall, I recommend doing a good amount of research.

Но он получит то, что ему причитается.  - Она встряхнула волосами и подмигнула. - Может быть, все-таки скажете что-нибудь. Что помогло бы мне? - сказал Беккер. Росио покачала головой: - Это .

 Сьюзан, - умоляюще произнес Стратмор, не выпуская ее из рук.  - Я все объясню. Она попыталась высвободиться. Коммандер не отпускал. Она попробовала закричать, но голос ей не повиновался.

Преступники, террористы и шпионы, которым надоело прослушивание их телефонов, с радостью встретили это новое средство глобальной коммуникации. Электронная почта соединила безопасность обычной почты со скоростью телефонной связи. С тех пор как сообщения стали передаваться по подземным волоконно-оптическим линиям, а не с помощью радиоволн, они оказались полностью защищенными от перехвата - таков по крайней мере был замысел. В действительности перехват электронных писем, передвигаемых по Интернету, был детской забавой для технических гуру из АНБ.

Ее молитва была проста: она просила Бога защитить любимого человека.

Сьюзан пронзила ужасная мысль. Этой своей мнимой перепиской Танкадо мог убедить Стратмора в чем угодно. Она вспомнила свою первую реакцию на рассказ Стратмора об алгоритме, не поддающемся взлому.

Шесть секунд. - Утечка информации. - Никаких изменений.

На центральном экране прямо под извещением об ошибке ВР представила зрителям ужасающую картину. По мере того как рушилась третья защитная стенка, полдюжины черных линий, эти хакеры-мародеры, устремлялись вперед, неуклонно продвигаясь к сердцевине. С каждым мгновением появлялась новая линия, а за ней - следующая.

И ТРАНСТЕКСТ больше не нужен.

Самая грязная ванна, какую мне доводилось видеть. И самый мерзкий пляж, покрытый острыми камнями. Этого и ждут от меня читатели. Больные на соседних койках начали приподниматься, чтобы разглядеть, что происходит.

 - Дэвид. В этот момент в нескольких метрах под помещением шифровалки Стратмор сошел с лестницы на площадку. Сегодняшний день стал для него днем сплошных фиаско. То, что началось как в высшей степени патриотическая миссия, самым неожиданным образом вышло из-под контроля.

Странно, подумал он, что сегодня вечером уже второй человек интересуется этим немцем. - Мистер Густафсон? - не удержался от смешка Ролдан.  - Ну .

Через несколько мгновений компьютер подал звуковой сигнал.

 Северная Дакота, - вслух произнесла она, пытаясь своим умом криптографа проникнуть в скрытый смысл этого имени.  - Что говорится в его посланиях на имя Танкадо. - Понятия не имею. КОМИНТ засек лишь исходящую почту.
