Thus, many multinational companies and even different business firms ask a variety of cybersecurity interview questions to not only fresh recruits but also experienced individuals wishing to display their talent and knowledge in this field. Here are some important cybersecurity interview questions that will not only give you a basic idea of the field but also help to clear the interview.
Start by explaining vulnerability, and threat and lastly risk.
Vulnerability (weakness) is a break in the security efforts of a system whereas a threat is an intruder who misuses that vulnerability. The risk is the measure of possible loss when the threat exploits that vulnerability. You may also give an example of your own.
CSRF is an acronym for Cross-Site Request Forgery, which is a web application vulnerability wherein the server does not verify whether the request has come from a trusted client or not. The request is processed immediately. It can be in addition accompanied by the methods to become aware of such conditions using examples and countermeasures.
Security Misconfiguration is also a vulnerability condition like CSRF that occurs when a device, application or network is configured such a way that it can be easily exploited by an attacker. Examples of such kind of threat include keeping the sample username and password, using too simple combinations for all the devices, etc.
In order to manage an antivirus alert, firstly check the policy concerning the antivirus and the alert. If the alert is genuine, it can then be whitelisted or else it is deleted or quarantined. After which the hash of the file is checked for reputation on different websites. Finally, the antivirus is fine-tuned so as to reduce the threat and protect the device.
Data leakage occurs when the data gets out the organization in an unauthorized manner. Data can be leaked in multiple ways such as emails, prints, losing laptops, the uploading of unauthorized data to different public portals, photographs, etc.
In order to detect and prevent leakage of data, various control measures can be taken. They include:
Data is generally classified into the following three levels:
Data has to be classified into different categories so that the severity (in case of leakage) can be well defined and identified. Without proper segregation of data, the crucial piece of information cannot be classified as critical or non-critical for other members of the organization.
Various methods adopted to ensure that employees are aware of the security policies and procedures include:
