Network Security
                     NETWORK SECURITY
What is Network Security?
• Network Security protects your network and data from breaches, intrusions and other threats. This is 
a vast and overarching term that describes hardware and software solutions as well as processes or 
rules and configurations relating to network use, accessibility, and overall threat protection.

Why Network Security?
• Network Security involves access control, virus and antivirus software, application security, network 
analytics, types of network-related security (endpoint, web, wireless), firewalls, VPN encryption and 
more.

Benefits of Network Security
• Network Security is vital in protecting client data and information, keeping shared data secure and 
ensuring reliable access and network performance as well as protection from cyber threats.
• A well designed network security solution reduces overhead expenses and safeguards organizations 
from costly losses that occur from a data breach or other security incident.

TYPES OF NETWORK SECURITY DEVICES AND TOOLS
Access control
• This refers to controlling which users have access to the network or especially sensitive sections of 
the network. 
• Using security policies, you can restrict network access to only recognized users and devices or grant 
limited access to noncompliant devices or guest users.

Antivirus and anti-malware software
• Malware, or “malicious software,” is a common form of cyberattack that comes in many different 
shapes and sizes. 
• Some variations work quickly to delete files or corrupt data, while others can lie dormant for long 
periods of time and quietly allow hackers a back door into your systems.

Application security
• Each device and software product used within your networking environment offers a potential way in 
for hackers. 
• For this reason, it is important that all programs be kept up-to-date and patched to prevent 
cyberattacks from exploiting vulnerabilities to access sensitive data.

Behavioral analytics
• In order to identify abnormal behavior, security support personnel need to establish a baseline of 
what constitutes normal behavior for a given customer’s users, applications, and network.

Data loss prevention
• Data loss prevention (DLP) technologies are those that prevent an organization’s employees from 
sharing valuable company information or sensitive data whether unwittingly or with ill intent outside 
the network.

Distributed denial of service prevention
• Distributed denial of service (DDoS) attacks are becoming increasingly common. They function by 
overloading a network with one-sided connection requests that eventually cause the network to 
crash.

Email security
• Email is an especially important factor to consider when implementing networking security tools. 
Numerous threat vectors, like scams, phishing, malware, and suspicious links, can be attached to or 
incorporated into emails.
