Part A description:
1. Topic – Network security Vulnerability and its impact on threats and attacks
System security challenges have increased over the years especially with critical systems such as
banking, healthcare, and the use of advance utilities becoming more connected. On the other hand,
the malicious actors have evolved from early-day hackers whose intentions were mostly curiosity to
modern-day hackers who has the intentions of financial gain to espionage and beyond. To effectively
secure against these threats and attacks, it is important to understand what we are securing, how we
are securing it, and who we are securing against.
You need to cover the following topics to secure the company network:
1. Identify a target company: You need to select an existing company and describe its
current network setup, business mission/objectives, and historical attacks if existed.
This company should have multiple branches nationally and/or internationally that are
connected over internet.
2. Know The Enemy. You need to conduct a research and identify the possible enemy
according to business of the selected company, and what would motivate them to
conduct possible attacks.
3. Know The Self. Threat is the presence of something valuable that makes a threat credible.
The value and nature of a valuable define the nature of the threat, the risk posed by a
threat, and the cost of defense. You need to define/list the assets that you have to protect,
the risks associated with those assets, and the costs of protecting or not protecting them,
so you can define the threat to your network. This analysis of an organization’s assets and
risks would lead to create a proper security policy. You need to prepare the following:
