What is Cyber security?

Cyber security could be defined as a process of ensuring maximum computer system protection along with many networks connected to the same. It is the method of protecting a computer system from unauthorized access.

Cyber security protects the computer, server, mobile devices, systems and networks from any damage and keeps the data safe.

What is Spooling?

Spooling (SPOOL means Simultaneous Peripheral Operations Online) and it’s a method of multi-programming by copying and mediating data to different devices. Like the non-technical meaning of reeling a thread on a spool, a document is reeled up on a spool so that it can later be unreeled without any data loss or damage. 

What is Spooling in Cyber Security?

Spooling helps to store the information in an intermediate platform before its execution. It helps for security purposes, as the data within the document is safe from getting distorted or unauthorized access from malicious websites. Several well-known tech companies are still trying to enhance their Spooling activities to maintain better Cyber Security.

For Example: Microsoft’s powerful and famous company is still struggling to improve its overall security services by enhancing its Print Spooler system. It would help Microsoft to maintain the safety and security of each client’s data.

What Spooling Is Used for?

Spooling is used for computing and storing information in the intermediate platform. There are several uses of spooling. One of the most important uses of Spooling is in printing. For example, the print spoolers are used for printing purposes as they temporarily store the data or commands in the Spool until the multi-function printer is ready.

Print spoolers are prone to attacks from malicious websites, and it is because these spoolers let non-administrative users enter during the temporary holding of the data. 

How does Spooling work in Cyber Security?

Here’s the working mechanism of Spooling in Cyber Security:

  • The first step of Spooling involves forming a buffer, SPOOL. This Spool helps in holding the data temporarily. 
  • The data uses Secondary Storage or Memory as its Spool. As soon as the slower device gets ready to operate the data, the Spool gets loaded into the primary storage or memory. 
  • After this, the primary operations take place. 
  • After the IO Devices are set in, the information goes from the Input Device (multiple numbers of Input devices can be connected simultaneously).
  • It is time to start operations with the CPU by not keeping it idle. A long queue is generated, resulting in the CPU output upon exhaustion.
  • It is followed by the output information from the injected device (in most cases, the printer). Thus, through a few complex steps, Spooling works.

How do we prevent Spooling attacks?

In Cyber Security, the more systems we secure, the more secure we all are. To make the system more secure through Spooling, we must prevent it from further attacks. Here are some effective ways to prevent Spooling attacks:

1. By Blocking the Unnecessary Servers

The settings that give access to unauthorized users should be changed in Print Spoolers. A larger network makes changing the settings more complex, but you can save your spooler from attacks after a while.

2. Root Out Malware

Some malicious software or a few malicious files make your computer system slow during spooling. You can root them out by going through a few complex steps of identifying the file and then blocking them. 

3. Revise your Access Policies

Once you have learned to use spoolers, it is crucial to go through and update your Access Denial Policy. The companies should create better Access Denial policies to stop the unauthorized access of specific malicious files. For example, companies like Microsoft have strengthened and hardened their Access Denial policies, and hence, they have been excelling in terms of Cyber Security. 

What are the advantages and Disadvantages of Spooling?

Advantages of Spooling:

  • Through Spooling, several IO (Input/Output) Devices can be used together. No interference of the IO Devices will occur between each other. 
  • Thanks to Spooling, no interference between the CPU and the IO Devices occurs.
  • Generally, the CPU isn’t efficient in its idle state. Hence in spooling, the CPU is mainly kept busy. The CPU becomes inactive whenever the queue gets exhausted after all the tasks are finished.
  • Spooling helps the applications to run at their best speed while the IO Devices work at their respective speeds.

Disadvantages of Spooling:

  • Spooling takes in huge storage. The storage size depends on the total number of requests from the Input Devices.
  • Since Spooling mainly occupies the maximum of the secondary storage, it may increase the risk of disc traffic. Hence, the disc gets slower with increased traffic (due to Input Devices).
  • Spooling transport data from a slower device to a faster device. The transfer process creates a disadvantage where the SPOOL fails to work in real-time. It results in the Output being produced later compared to the actual time.
