In the world of Chief Information Security Officer (CISO) of a small to mid-sized company, the
primary responsibility revolves around developing and implementing a solid cybersecurity
strategy. This strategy primarily focuses on protecting Personally Identifiable Information (PII),
safeguarding property, and ensuring compliance with international regulations such as GDPR. To
achieve these goals, they need to employ a range of cybersecurity measures, tools, and
technologies that are carefully chosen based on their effectiveness and compatibility with our
specific operational requirements.
The reliance on solutions like Palo Alto Networks’ next-generation firewalls (NGFW) for
application-layer firewalling is well-founded. These firewalls, with their Deep Packet Inspection
(DPI) and stateful inspection techniques, are highly effective in identifying instances of PII
exfiltration. Their seamless integration with our Transport Layer Security (TLS) protocols further
enhances their value in encrypting data transmissions (Smith & Johnson, 2019; Easttom, 2021
Chapter 2).
The Intrusion Prevention System (IPS) setup includes solutions such as Cisco’s Firepower IPS,
which is highly regarded for analyzing network traffic. It applies a combination of signature-based,
anomaly-based, and policy-based detection methods to effectively identify patterns that may
indicate breaches involving PII data (Davis, 2020; Easttom, 2021 Chapter 3).
On the other hand, network security is bolstered using Deep Packet Inspection (DPI) solutions
such as Fortinet FortiGate. These capabilities allow us to conduct a thorough analysis of the header
and network traffic payload, leaving no room for potential threats. This thoroughness in identifying
and stopping any transmission of PII data, combined with the integration of this technology with
our encryption protocols, such as TLS IPsec, further enhances the security of data transmission.
For Virtual Private Network (VPN) solutions, a company can utilize various options, such as
NordVPN Teams, which provides robust AES-256 encryption within IPsec protocols for remote
access. Alongside this encryption, a company can implement multi-factor authentication (MFA)
processes to ensure that remote access remains secure and compliant when accessing data.
To protect against threats, a company can utilize Symantec’s ATP solutions. These solutions
include sandboxing environments that safely execute and analyze suspicious code. Additionally,
they provide real-time threat intelligence feeds, which are crucial in safeguarding against zero-day
exploits that could potentially compromise PII.
To further strengthen the Data Loss Prevention (DLP) strategy, a company relies on various
comprehensive solutions, such as McAfee Total Protection. This software utilizes advanced pattern
recognition algorithms to identify and prevent any access or transfer of PII. They can also
incorporate industry encryption protocols, standards, and best practices following NIST’s
guidelines to guarantee our data’s confidentiality and integrity (Jones, 2021; Easttom, 2021
Chapter 2; NIST, 2019; Easttom, 2021 Chapter 1).
Furthermore, a company can utilize the Splunk User Behavior Analytics tool for User and Entity
Behavior Analytics (UEBA). This tool monitors any unusual access or usage patterns associated
with PII data. It helps to identify insider threats or compromised accounts (Clark & Adams, 2022;
Easttom, 2021 Chapter 3). A company should regularly conduct security audits and penetration
testing using tools like Nessus. These tests assist in identifying and resolving vulnerabilities within
the infrastructure (Taylor, 2020; Easttom, 2021 Chapter 5).
Maintaining a balance between these measures and the need for efficient collaboration while
complying with data protection laws such as GDPR poses significant challenges. CISO’s
responsibility involves ensuring that our security infrastructure boasts advanced technology and
promotes operational efficiency while adhering to global data protection standards.
In summary, as a CISO, the approach revolves around integrating market-leading cybersecurity
products and technologies that are meticulously chosen to cater to aspects of all security
requirements. Taking this approach, we will constantly enhance it, seek to safeguard PII data,
promote global cooperation, and guarantee adherence to various data protection regulations.
