Explain what a honeypot is. In your explanation, give at least one advantage and one disadvantage of deploying a honeypot on a c

tatuchka [14]

Answer:

A honeypot is a computer network set up to act as a decoy to track, deflect, or research trying to obtain unwanted access to the information system.

Explanation:

A honeypot is a device or device network designed to imitate possible cyber-attack targets. It can be utilized to detect or deflect assaults from a legitimate military target. It may also be used to collect knowledge on how cybercrime works.

Advantage:-

Data Value:- One of the challenges faced by the research community is to obtain meaning from big data. Companies hold large quantities of data daily including firewall logs, device logs, and warnings for vulnerability scanning.

Resources:- The problem facing most protection systems is resource shortages or even the depletion of resources. Power saturation is when a protection asset can no longer work since it is overloaded by its assets.

Simplicity :- I find simplicity to be the biggest single strength of honeypots. No flashy techniques are to be created, no stamp computer systems to be managed, no rule units to be misconfigured.

Disadvantage:-

That honeypot doesn't replace any safety mechanisms; they just operate with your overall security infrastructure and improve it.

What is TLB for? Why TLB? Given the following number, what is theeffective memory access time?

vodomira [7]

Answer:

A lookaside buffer translation (TLB) is a memory cache that reduces the time it takes to access a user memory place. TLB includes the most lately used page table entries.

TLB is used to overcome the issue of sizes at the time of paging. Page Table Entry (PTE) is used for framing the memory ,but it uses two references one for finding the frame number and the other for the address specified by frame number.

Formula for finding effective memory access time-

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

Given in question,

Hit ratio = 0.90

Memory Access Time = 150ns

TLB access time= 5ns

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

=(5+150) * 0.90 + (5+2*150)*(1-0.90)

=155 * 0.90 + (305*0.1)

=139.5 + 30.5

= 170ns
