                     NETWORK 
SECURITY
A boon for a secured 
virtual space
INTRODUCTION
With more than 4.1 billion users across the world, the internet and 
digital technology has swapped almost all spheres of human lives and 
thereby remaining up-to-date with contemporary technology becomes 
vital. 
With this great use , scope and span ; the internet also brings with 
itself black intentions of hackers and thereby network  security  
becomes a major aspect to be considered.
WHAT ARE THESE THREATS?
Cyber threats are the threats from various malicious softwares and 
software attackers which include
❖ Viruses 
❖ Trojan horses
❖ Malware
❖ Spyware and Adware
❖ Rogue Security Software
❖ Ransomware
❖ Phishing
❖ Hacking and cracking,etc 
The solution to our problem
                     NETWORK SECURITY
Prevention , protection and post-attack measures are the three broader 
approaches that we can employ to remain secure.
Security can be achieved at personal level via some simple tools and 
basic awareness  and at global level via strict cyber laws.  
Network security techniques :
❏ Antivirus 
 It is an software program that is employed in 
any system to prevent any malicious activity
It can be downloaded or purchased for 
securing systems against malicious attacks. 
It detects and removes malware and thereby 
helps us protect our system.
❏ Firewall 
These are used to protect internal/private                                           
                     networks. 
They can also be used to govern activities taking place within the 
network.
❏ Intrusion Detection System
           These are another major activity control system that can be used 
to detect          
           and report any unnecessary activity that takes place over the 
network.           
❏ Setting strong password
This technique can be employed at personal level 
via some basic awareness    while setting password 
which are
○ Use at least 4 characters
○ Use special characters along with regular 
alphabets
○ Initials from lines from any adage or any 
saying which is very personal to you can be 
used to set password 
○ Never share your password with anyone; if 
done then change your password as early 
as possible to prevent any misuse.
❏ Virtual Private Networks(VPNs)
These involve encryption process to attain security.
They are used to obtain privacy and data security 
over the internet via hiding your IP address and 
physical location.
❏ Email security application
It is an application specific protection technique. A 
safe mailing environment free of spams can be 
achieved via this as it blocks phishing, viruses, 
worms, etc. that may cause email security threats.
❏ IT Security Frameworks
They are used by private companies with 
good employee base to manage security 
within the entreprise.
Various companies depending on their 
size and security needs use this technique 
to ensure that things go safe within the 
organization.
Conclusion 
Various other techniques like data loss prevention, network 
segmentation, behavioral analytics, endpoint security, etc. can be used 
to protect the network.
Network security encompasses awareness at personal level much more 
than regulations; but strict action needs to be taken against any 
malicious activity if detected in order to obtain a safe virtual world.
