Network security is crucial for protecting computer networks from various cyber threats, especially for small businesses which are often targeted due to their lack of resources. Key threats include malware, phishing, and unsecured systems, highlighting the need for multi-layered security protocols. Implementing a structured approach involving the creation, testing, and ongoing monitoring of security systems is essential for safeguarding sensitive data and maintaining operational integrity.

2. *Intro to Network Security
Network Security is no joke. Whether you have a website, online accounts•
or any cyber-based infrastructure, you are at risk of a network attack.
Even though the public only hears about cyber attacks against large•
companies, banks and government websites, small businesses make the
best targets for cyber criminals.
Due to the lack of resources of small businesses, they have the least•
protected websites, accounts and network systems, making cyber attacks
against them a relatively easy job.

3. “Attacks against small
businesses continued to
grow in 2015, although
many of these attacks
were directed to fewer
organizations, increasing
by 9 percentage points.“

Mistakes
Uninformed
users opening phishing emails
Passwords
Passwords that are insecure or
don’t expire, along with default
password and user accounts left in
place
Out-of-date
operating systems with known
vulnerabilities left on the internet;
this can be a threat to other, more
up to date machines.

5. Network security is the
any protection of access,
misuse, and hacking of
files and directories in a
computer network system.
Some of the most
common threats to a
network include viruses,
worms, spyware, adware
and identity theft.
One of the most important
aspects is the multiple layers
of security. There is no single
package or system that will
offer complete protection
against every threat to your
network, so it is important to
remember to use multiple
layers of security for your
network.

6. As the internet evolves and
computer networks become bigger
and bigger, network security has
become one of the most important
factors for companies to consider.
By increasing your network
security, you decrease your chance
of compromising your data.
As the complexity of the systems
and the networks are increasing,
vulnerabilities are also increasing
and the task of securing the
networks is becoming more
complex. This makes network
security an essential part of today’s
businesses.

19. * 5 Steps to Protect Your Network
Implement Analyze Test Modify Monitor
The first step is to
create and implement a
network security system
system that provides
protection and has
sufficient authorization
policies.
Once the network
security system is
created and
implemented, the
system needs to be
analyzed to determine
if the current security
system is appropriate
for the network it is
protecting.
When an appropriate
network security
system is in place, it
is time to conduct
tests to make sure all
of the securities are
working and will
completely protect
your network against
any threats.
19
After conducting the
tests, collect the data
and enhance your
protections. The results
will reveal where your
security system is
effective and where it
can be improved.
Hackers are always
improving their
attacking procedures, so
it is essential to test
your system frequently
to remain protected and
stay one step ahead of
them.
Ongoing monitoring will
help support healthy
network operations at all
hours of the day.
Monitoring the network in
an ongoing fashion doesn’t
have to require more work
or office time. A network
monitoring solution will
keep tabs on device
statuses and send you real-
time alerts via email or
text anytime network
issues occur.
