Assess the likelihood and potential impact of risks, considering both frequency and severity.
Prioritize risks by assessing their severity and comparing them to your risk tolerance This allows for focused mitigation efforts on the most critical threats.
Mitigate risks by implementing appropriate safety measures, procedures, and controls to prevent incidents and negative consequences.
Assets, threats and threat identification procedures
Organizational assets, including data and devices, hold significant value, often due to their sensitive information or access capabilities.
Company assets include employee devices (desktops, laptops, phones) and their applications, as well as critical infrastructure like servers and support systems.
An organisation’s most common assets are information assets These are things such as databases and physical files – i.e the sensitive data that you store
Information assets reside in containers; for databases, this is the application, and for physical files, it's the filing cabinet.
A threat is any incident that could negatively affect an asset – for example, if it’s lost, knocked offline or accessed by an unauthorised party
Threats can be categorised as circumstances that compromise the confidentiality, integrity or availability of an asset, and can either be intentional or accidental
Intentional threats, like criminal hacking and insider theft, differ from accidental threats such as employee errors, technical malfunctions, or physical damage from events like fires or natural disasters.
A vulnerability is an organisational flaw that can be exploited by a threat to destroy, damage or compromise an asset
Software vulnerabilities, or bugs, are common due to software complexity and frequent updates, posing a significant risk of sensitive data breaches by malicious actors.
Vulnerabilities encompass technological flaws, physical weaknesses (like broken locks), and procedural shortcomings (e.g., inadequate employee processes), all potentially exposing sensitive information.
Cybersecurity threats stem from human error (phishing susceptibility), infrastructure weaknesses (e.g., faulty wiring), and communication failures (incorrect information sharing).
Threats come in many forms and through different channels, including:
Threats are often intentional and are done through hacking from an individual or a criminal organization A few intentional external threats include viruses, malware, Denial of Service (DoS) and ransomware attacks
Threats are sometimes accidents due to some internal issue such as a computer malfunction or employee lapse in protocol, judgment or memory
Natural disasters such as floods, earthquakes, fires, and lightning strikes pose significant threats to data integrity, potentially causing damage ranging from restricted access to complete data loss.
Internal threats, such as employee misconduct or occupational fraud, can significantly compromise asset security.

My concept will include these main areas:
DMZ area to serve for external internet
Private network area for the company
A Firewall between above areas (Using software firewall)
Therefore, there are 4 policies that I need to figure out:
The server cannot access the internet except during maintenance time
NAT policy to public server (Allow external computers to access indirectly to internal ones)
Only management IP (computer) can access Firewall, DMZ but no internet connection
Staff computers still access to the internet
DMZ area that is used to use different services such as folder sharing, mail service
A secure private network requires a management workstation, remotely accessing the server, accessible only to authorized staff This workstation needs to maintain a clean, internet-free environment (except during maintenance), while staff workstations retain internet connectivity.
Network implementation establishes a DMZ for external traffic and a private network for internal staff, separated by a software firewall with strict access control policies These policies include limiting server internet access to maintenance windows, using NAT for public server access, and granting management IP access to the firewall and DMZ only.
1) The server cannot access the internet except during maintenance time
Figure 10 Rule for blocking management workstation to the internet
2) Only management IP (computer) can access Firewall, DMZ but no internet connection
The first rule is allowing management workstation access to the pfsense server
The second one is allowing management workstation access to the DMZ area
The third one is blocking management workstation access to the internet
Figure 12 Rule for accessing Firewall, DMZ
3) NAT policy to public server (Allow external computers to access indirectly to internal ones)
This will direct port 7000 that comes from outside to the destination (Folder sharing service)
