A web application attack is an attack that targets a specific vulnerability in a web application in order to gain access to sensitive data or to disrupt the normal functioning of the application. There are many different types of web application attacks, but some of the most common include SQL injection attacks, cross-site scripting attacks, and denial of service attacks.

7. What type of protection mechanisms can be implemented against SQL injection attacks?

There are a few different types of protection mechanisms that can be implemented against SQL injection attacks. One is to use parameterized queries, which will ensure that only the parameters that are passed in by the user are used in the SQL query. Another is to use a whitelist of approved characters that can be used in the SQL query. Finally, you can also use a blacklist of characters that are not allowed in the SQL query.

8. What are some ways to secure sensitive information in databases?

There are a few different ways to secure sensitive information in databases:

1. Encrypting the data: This means that the data is converted into a code that can only be decoded by authorized users.
2. Hashing the data: This means that the data is converted into a unique string of characters that cannot be decoded.
3. Using access control lists: This means that only certain users are allowed to access the database, and that they can only do so with the appropriate permissions.
4. Using database activity monitoring: This means that all activity on the database is monitored and logged, so that any suspicious activity can be detected and dealt with.

9. What steps would you take if you wanted to stop bots from crawling your website?

If you wanted to stop bots from crawling your website, you could take a few different steps. You could use a CAPTCHA system to make it more difficult for bots to access your site.

12. What are some common techniques used by cyber criminals when launching a DDoS attack?

Some common techniques used by cyber criminals when launching a DDoS attack include:

-Sending large amounts of traffic to the target server in order to overload it and cause it to crash.
-Attempting to access the target server with a large number of requests in order to overload it and cause it to crash.
-Flooding the target server with requests that consume a lot of resources, such as CPU or memory, in order to make it unavailable to legitimate users.

13. What are some strategies you can use to mitigate DDoS attacks?

Some strategies you can use to mitigate DDoS attacks include:

-Using a DDoS protection service
– rate limiting
– blacklisting
– whitelisting
– using a content delivery network
– using a web application firewall

14. Can you explain what a man in the middle attack is?

A man in the middle attack is a type of cyber attack where the attacker inserts themselves into a communication between two parties in order to eavesdrop or tamper with the data being exchanged. This can be done by either intercepting messages between the two parties or by impersonating one of the parties and fooling the other party into thinking they are communicating with the legitimate party when they are actually communicating with the attacker.

15. Why is it important to have good IT security policies in place before moving to the cloud?

There are a few reasons why it is important to have good IT security policies in place before moving to the cloud. First, the cloud is a shared environment, so it is important to have policies in place to ensure that your data is secure and not accessible to unauthorized users. Second, the cloud is a dynamic environment, so it is important to have policies in place that can adapt to changes in the environment. Finally, the cloud is a global environment, so it is important to have policies in place that can be applied across different geographical regions.

16. What should we look for when evaluating software designed to protect our systems from attack?

When looking for software to protect your systems, you should consider the following:

-The company’s reputation and history
-The software’s features and capabilities
-The software’s ease of use
-The software’s price

You should also make sure to read reviews of the software before making a decision.

17. What is Data Governance?

Data governance is the process of ensuring that data is accurate, consistent, and compliant with organizational policies. This involves establishing processes and controls to manage data throughout its lifecycle, from creation and ingestion to storage, processing, and archival. Data governance can help organizations to improve the quality of their data, reduce costs, and mitigate risks.

18. What are some steps businesses can take to ensure proper governance over data?

There are a few key steps businesses can take to ensure proper governance over data:

1. Establish clear roles and responsibilities for data governance.

2. Define and document clear policies and procedures for managing data.

3. Implement technologies and tools to help automate data governance processes.

4. Monitor and audit data governance processes on a regular basis.

19. Can you explain what a privileged user account is?

A privileged user account is an account that has been given elevated permissions within a system. This could be an administrator account that can make changes to system settings, or a user account that has been given access to sensitive data. Privileged user accounts can pose a security risk if they are not properly managed, as they can be used to bypass security controls or gain access to sensitive information.

20. What is the best way to manage privileged user accounts in a large organization?

There are a few different ways to manage privileged user accounts in a large organization, but the best way will likely depend on the specific needs of the organization. One way to manage privileged user accounts is to use a centralized system that can track and manage all of the accounts in one place. Another way to manage privileged user accounts is to use a role-based approach, where different users are given different levels of access based on their role within the organization.
