- Programmers in general should learn to avoid writing code that is vulnerable to buffer overflow attacks. A. Why is this not a sufficient defense vs. buffer overflow attacks? B. Please give another defense that can be used vs. buffer overflow attacks. C. Please give a third defense that can be used vs. buffer overflow attacks.Explain Buffer Overflow Attacks and Input Validation Attacks commonly utilized on Unix OS . ( CLO 3 )Q: Are stack overflows the only type of vulnerability produced by buffer overflows?
- Write any bash script that will automate some routine operating system tasks related to proces management, users and groups management, memory management, etc.the least privilege principle is not useful for operating system hardening True FalseDon't merely state that deep access is faster than shallow access without explaining why it's better to utilize deep access in code.
- Answer it True or False only. No explanation. Thanks 1. A security failure is a scenario where the software system does not achieve its security objective, and a vulnerability is the underlying cause of such a failure. 2. A temporal vulnerability is a bug where the program is indexing into a valid contiguous range of memory cells, but the index is out-of-bounds. 3. A spatial vulnerability is a bug where the program accesses memory that was once allocated to the program, but has since been deallocated. 4. The execution of a program is ultimately a physical process, typically involving digital electronic circuitry that consumes power, emits electro-magnetic radiation, and takes time to execute to completion. 5. A side-channel is an information channel that communicates information about the execution of a software program by means of such effects from which the program’s code abstracts.Some common technologies (approaches) used to persist object state include: native Java serialization, JSON, and Google protobufs. Compare and contrast the above three technologiesYou should not argue that deep access is better than shallow access just because of performance improvements.
- Last Stage of Delirium, a security study organisation, created some clean portbinding shellcode for Linux. Shellcode that is clean is shellcode without any NULL symbols. As was already stated, NULL characters prevent the majority of buffer overflow vulnerabilities from being exploited properly because the function stops copying when a NULL byte is encountered. EConsider the fault detection tactics (ping/echo, heartbeat, system monitor, voting, and exception detection). What are the performance implications of using these tactics?It is possible to recover information from memory either sequentially or immediately. So, why do most cutting-edge gadgets employ direct access, and what are its benefits? How can information developed in a sequential-access environment be made accessible in a direct-access environment?
