Introduction

In the world of cybersecurity, Fortinet Firewall is a name that commands attention. With the ever-growing complexity of online threats and the need for robust network security, Fortinet Firewall has emerged as a stalwart defender of digital landscapes. In this comprehensive guide, we will delve into the realm of Fortinet Firewall, exploring its features, capabilities, and its role in safeguarding critical data and networks. Additionally, we will demystify essential security terms that are crucial for understanding the intricate world of network protection. Join us on this journey to gain a deeper insight into Fortinet Firewall and the key security concepts that underpin it.

CHAPTER – 1

Common Network Security Terms:

Key Network Security technical terms are Asset, Vulnerability, Exploit, Threat, Attack, Risk and
Countermeasures.

Asset:

Examples: Properties, Vehicles, Heavy Equipment, Plants, Buildings, Employees, Computers, Data,
Intellectual Properties etc. Protecting the organization’s assets is the prime function of security
(Physical Security or Network Security).

Vulnerability:

Vulnerability can be defined a weakness in a system or its design. Every system is human created.
Chances for errors, mistakes are always there in every human created system. Vulnerabilities are
always there in Applications, Network Protocols, and Operating Systems etc. An attacker to gain
access to an organization’s network can exploit vulnerability.

Exploit:

An Exploit can be defined as a way, method or tool which is used by an attacker, on a vulnerability, to
cause damage to the target network or system. The exploit can be software that may cause a buffer
overflow or a method of social engineering to hack a password.

Threat:

negative consequence of an organization’s Asset. Risk arises from a threat, multiple threats, and exploiting vulnerability. Risk forms an adverse negative affect an organization’s Asset.

Risk = Asset + Threat + Vulnerability 

Countermeasure:

Countermeasure is an action initiated by the organization typically security professionals to mitigate a threat.

Common Security Terms:

Key Network Security technical terms are Asset, Vulnerability, Exploit, Threat, Attack, Risk and
Countermeasures.

Identify Malware:

  • Malware is an inclusive term for all types of malicious software.
  • Malware is terms for all as Viruses, Worms, Trojans, Rootkits, and Spyware.
  • Malware is also terms for Adware, Scareware, Botnets, Logic Bombs, Key loggers etc.
  • Many tools can identify Malware on the network such as Packet Captures to analyzing.
  • In addition, tools Snort, NetFlow, IPS, Advanced Malware Protection, Cisco Fire POWER etc.

Virus:

  • Malicious code that attached to executable files that are often a regular application.
  • Most virus require end-user activation to damage the system or device.

Adware:

  • Keyloggers store the gathered information and send it to the attacker.
  • Attacker extract sensitive information like password or credit card details.

Scareware:

  • Scareware is a type of malware designed to trick victims.
  • Scareware trick victims into purchasing and downloading useless software.
  • Scareware trick victims into download potentially dangerous software.
  • Scareware, which generates pop-ups that resemble Windows system messages.
  • Scareware usually purports to be antivirus or antispyware software.
  • Scareware also usually popup a firewall application or a registry cleaner.
  • The messages typically say that a large number of problems such as infected files.
  • The user is prompted to purchase software to fix the problems.
