Virtual Router System (VRS)
Virtual router instances communicate with a Point-Of-Presence (POP) and
follow a star topology, in which a single core node is connected to Customer
Edge Gateways (CEG) linked through Intermediate Nodes (INs).
Vulnerability
A weakness or gap in a security system that can be either exploited by
attackers or caused by malfunctioning system components.
Threat
The possibility of exploration of vulnerabilities that can lead to something bad
happening, and it emphasizes the qualitative of potential damages due to
explored vulnerabilities.
Attack
An action triggered by deploying an attacking method, when a vulnerability is
exploited to actually realize a threat.
,Risk
The quantifiable likelihood of loss due to a realized threat, and it emphasizes the
quantitative of potential damages.
The source of attacks
Two types of attackers based on their origins called inside attacker (or insider)
and outside attacker (or out sider).
The method of attacks
There are two types of attack methods based on the intention of the attacker
called passive attacks and active attacks.
The target of attacks
The objective of attackers to try to compromise.
The consequence of attacks
Describes outcomes by successfully deploying an attack. It is a multi-faceted
consequence.
Defense in depth
Also known as Castle Approach is the concept of protecting a computer
network with a series of defensive mechanisms such that if one mechanism
fails, another will already be in place to thwart an attack.
,Defense in depth framework
The first layer is a prevention mechanism that stops attacks from getting into the
networking system.
The second layer is detection and response mechanisms that watch activities on
systems and networks to detect attacks and repair the damage
The third layer is attack-resilient technologies that enable the core elements,
or, the most valuable systems, on the network to survive attacks and continue
to function.
Cyber Kill Chain
Adopts the concept of a procedural step-by-step attacking method consisting
of target identification, force dispatch to target, decision and order to attack
the target, and finally the destruction of the target.
Reconnaissance
The attacker gathers information on the target before the actual attack starts.
Weaponization
Cyber attackers do not interact with the intended victim, instead they create their
attack.
Delivery
Transmission of the attack to the intended victim(s).
, Exploitation
This implies actual detonation of the attack, such as the exploit running on the
system.
Installation
The attacker may install malware on the victim.
Command & Control (C&C)
This implies that once a system is compromised and / or infected, the system has
to call home.
Actions on Objectives
Once the cyber attackers establish access to the organization, they then
execute actions to achieve their objectives / goal.
Network mapping
The study of the connectivity of networks at the layer 3 on a TCP / IP network.
Vulnerability scanning
An inspection of the potential points of exploit on a computer or network to
identify security holes.
Penetration testing
Attempts to identify insecure business processes, insecure system settings, or
other weaknesses.
