Explain three methods to prevent and/or detect buffer overflow attacks. (Hint: for the buffer overflow lab we disabled some defenses. feel free to google those defenses).
Step by step
Solved in 2 steps
- 1) Please explain the key fact relating to where local variables are stored that makes buffer overflow attacks possible. 2) Pick a defense that addresses the security concerns arising from the problem you identified in part 1, and explain how it addresses them.What are buffer overflow vulnerabilities?Both buffer-overflow and format-string vulnerabilities can lead to the modification of the return address field, but the ways how the field is modified are different in these two attacks. Please describe their differences, and comment on which one is less restricted.
- Why do buffer overflow vulnerabilities exist?Distinguish between differential and incremental backups, with a focus on database backups and restores, as well as their dependability (do they always work?).Explain the concept of hypervisor-based and container-based security in virtualized environments. What security measures can be taken to protect against vulnerabilities?
- Explain why each of the following protocols should or should not be used:• Multiversion timestamp ordering • Multiversion two-phase lockingIt's possible that doing a server database migration might come with certain hazards?How does memory encryption work, and why is it crucial for data security in cloud computing and virtualized environments?
- Database backup and recovery protocols should be discussed, as should their significance. The next step is to discuss the components that a backup and recovery strategy must contain.What is deadlock prevention? Explain how this may be achieved?Is it possible for a data breach to significantly impact the degree of security offered by cloud storage? Is there anything you can do to fight back, or do your options appear to be pretty limited at this point?
