🛠️ Enhanced Help Desk and Monitoring Capabilities

Help desks often utilize automation to streamline support processes. Automation can convert email submissions into help desk tickets and assign them appropriately. By monitoring resources with scripts, potential problems can be identified and resolved before escalation is needed. Scripts can enable or disable services based on specific time frames. Developers use scripting for continuous code updates and cloud infrastructure management, interacting with APIs to control devices programmatically. However, scripting requires careful implementation and testing to ensure compatibility with other systems. Creating and maintaining scripts involves time and costs. Scripts can become single points of failure if not properly managed. Organizations need to address root problems rather than merely treating symptoms to avoid increasing technical debt. Continuous support and updates for scripts are essential to keep up with changes in systems and scripting languages.

Transcripts

Scripting allows for the automation of functions

that normally you would have to perform manually.

This means, when situations occur,

you don't necessarily have to be there to resolve the problems.

You have a script that does that for you.

This also means that you don't have to receive a phone

call in the middle of the night disrupting your sleep

as you're trying to resolve a problem manually,

and you can sometimes identify problems

before they occur and automate the process of resolving them

before anyone knows an issue was even there.

Another great advantage of scripting is that it's fast.

It runs as fast as the computing systems that it resides on,

and you don't have to worry about somebody

typing things in or misspelling anything.

Once you've set up a script and tested it,

it can run without any type of delay or errors.

And if we have a script that's performing processes for us,

we can do other things that are much more interesting

than typing at a command line.

Scripting certainly saves a lot of time.

We can run these scripts whenever we might need them.

They can perform their functions over and over again.

And you won't have to provide any type of human intervention.

Automation can also help us enforce security baselines.

We might have a script that is providing an update

or upgrade with security patches,

and that script waits for the patch

to arrive in a particular folder,

identifies that a new patch exists,

and then automatically deploys that patch

to all of the systems that need it.

I've also configured scripts for infrastructure configurations,

especially when setting up multiple systems

that all need to have exactly the same security.

You might set up a script that automatically builds a default

router configuration with all the unique settings

that your organization requires.

Maybe you have a script that creates firewall rules any time

you deploy a new firewall to a remote site.

Or maybe there's a script that runs configurations, sets

security rules, or configures standard configuration

options within a single device.

By using a script to provide this configuration,

we not only know that we're putting

in a correct configuration, but it's

one that includes all of the security controls required.

You're probably familiar with the process

of scaling up or scaling down a cloud-based application

infrastructure.

When you're scaling these systems up,

you're adding new servers and new databases.

But you also need to add new security features.

And you can scale up the security along

with everything else for that application in the cloud.

You just have to make sure that you build your scripts

to not only include the servers and databases but also

the firewalls and other security devices along with it.

This is also great for members of your information technology

staff.

Instead of everyone manually typing in and dealing

with problems on an ad-hoc basis,

you can create scripts that perform many of those functions

automatically, and they can move away from the boring tasks

and concentrate on something that's much more interesting.

Automation has the ability to react very quickly when

a problem is identified.

We can set up constant monitoring of a system.

And if anything changes in that system that

needs to be addressed, we can automatically

apply those changes.

For example, we might monitor a server for available disk

space.

And if we identify that the disk space is becoming low,

we can have a script go into temporary files

and clear out some of that space so that the system remains

up and running.

And since these scripts run 24 hours a day and 7 days a week,

we don't have to have an individual manually

monitoring a server for disk space.

We can simply have the scripts take

care of all of that for us.

Many organizations will automate the process

of onboarding and offboarding.

When you're onboarding, there are

a core set of resources that almost every employee needs

access to.

For example, they will need their own home directory.

They'll need access to a printer that's near them.

And they'll need access to email.

An onboarding script can automatically

create the user's account, assign them

to the correct groups, and make sure they

have access to the files and resources they need.

Automation can also be used two stop payments

from making mistakes.

We refer to these as guardrails.

The guardrail is an automated verification of information

going into a system.

So a human might be typing into a server,

but an automated script is going to verify

the information that's being input

and make sure that the information is not

going to cause a problem with that destination system.

For example, a technician may try

to delete a folder on a server but mistakenly chooses

a much larger area of the server to delete.

By using guardrails, we can have this automation monitor

that process and block anything that would cause

critical files to be deleted.

Throughout a normal workday, there

may be constant changes to the security groups associated

with the employees in your organization.

And because of that, you might want an automated system

to be able to add and remove users from particular security

groups.

This can also be very useful for monitoring security groups.

For example, you may want to create

a report or an alert that monitors the administrator

group.

And if a person is added to the administrator group,

you would be informed immediately.

If you work in an organization with a help desk,

you may be already using automation.

Many help desks support the ability to email the help desk.

The automation can take an email submission,

turn that email into a help desk ticket,

and, based on the information that's in the email,

can even assign that ticket to the appropriate person.

And if we're monitoring the right resources

with our scripts, we can identify problems

before they become an issue.

Normally, this issue would occur,

and we'd have to escalate the problem to a higher level

technician.

But if we're constantly monitoring these resources,

we may be able to have the script resolve

the problem for us without any human intervention.

If the script is not able to resolve this problem,

it can automatically escalate the issue

to the technician who's on call.

Automation can also be used to enable or disable services.

For example, if a service needs to be

used for a certain amount of time,

you can have the script enable the service.

And then after that time frame is complete,

it can then disable the service without any human intervention.

Application developers can use scripting

to provide constant development and code updates

and push those code updates automatically out to systems.

And when you're working with a cloud-based infrastructure,

a firewall, or almost any other device in your infrastructure,

you may want to use automation to speak

directly to the application programming

interfaces, or APIs, on those devices.

This allows you to programmatically control

those devices without manually having to log in

and click things on the screen.

The script handles the process of communicating to the API

and making any changes necessary on that device.

But, of course, scripting is not a panacea,

and there are important concerns when implementing

any type of automation.

For example, scripts are relatively complex,

and they have to interact with other devices

and other systems.

This requires a great deal of testing

to make sure that all of these will work well together.

These scripts also don't create themselves.

Someone does have to sit down and go

through the process of coding out

all of these different scripts.

That means that there's not only time involved but also

a cost associated with that script creation.

And like any other device that may be in your network,

that script could be a single point of failure.

If that script stops working, there

could be a significant problem with the devices that

rely on that automation.

I've personally worked with organizations

that spend a lot of time working on issues that

come up throughout the day.

And a lot of this work seems to revolve

around solving the symptoms that have

been created instead of addressing

the core root of the problems.

We refer to this as technical debt,

and sometimes creating a script to hide a much bigger problem

can increase the amount of technical debt

in your organization.

And of course, someone has to support

this script going forward.

This script may be working fine today.

But later on, you might change the type of operating system

associated with the service, the scripting language

might have modifications, and someone

will need to update these scripts to bring them up

to the latest versions.
