Introduction

Michel Foucault’s concept of “power/knowledge” reveals how control and information are deeply intertwined—a principle that resonates in modern cybersecurity. Just as Foucault analyzed societal power structures, cybersecurity professionals must understand how knowledge (data, access, and intelligence) shapes digital dominance and vulnerability.

Learning Objectives

  • Understand how Foucault’s “power/knowledge” applies to cybersecurity.
  • Learn practical commands to audit and secure systems.
  • Explore how threat actors exploit knowledge gaps for control.

1. Auditing User Permissions in Linux

Command:

sudo find / -type f -perm -4000 -exec ls -ld {} \; 2>/dev/null

What It Does:

Lists all SUID (Set User ID) files, which can be exploited for privilege escalation.

Step-by-Step Guide:

1. Run the command to identify SUID binaries.

  1. Check if any unusual binaries (e.g., /bin/bash) have SUID permissions.

3. Remove unnecessary SUID bits with:

sudo chmod u-s /path/to/file

2. Detecting Windows Lateral Movement

Command (PowerShell):

Get-WinEvent -LogName Security | Where-Object {$<em>.ID -eq 4624 -and $</em>.Properties[bash].Value -eq 3}

What It Does:

Identifies remote login events (e.g., Pass-the-Hash attacks).

Step-by-Step Guide:

  1. Execute in PowerShell to review Event ID 4624 (logon events).

2. Filter for “Logon Type 3” (network logins).

3. Investigate anomalous IPs or usernames.

3. Hardening API Security

Command (curl for testing):

curl -H "Authorization: Bearer <token>" -X GET https://api.example.com/data --verbose

What It Does:

Tests API endpoint authentication.

Step-by-Step Guide:

  1. Replace `` with a valid JWT or API key.
  2. Check response headers for misconfigurations (e.g., missing HTTP Strict Transport Security).

3. Enforce rate limiting and OAuth2 scopes.

4. Cloud Hardening (AWS S3 Buckets)

Command (AWS CLI):

aws s3api put-bucket-policy --bucket my-bucket --policy file://policy.json

Policy.json Example:

{
"Version": "2012-10-17",
"Statement": [{
"Effect": "Deny",
"Principal": "",
"Action": "s3:",
"Resource": "arn:aws:s3:::my-bucket/",
"Condition": {"Bool": {"aws:SecureTransport": false}}
}]
}

What It Does:

Blocks unencrypted (HTTP) access to S3 buckets.

5. Mitigating SQL Injection

Code Snippet (PHP Prepared Statement):

$stmt = $pdo->prepare("SELECT  FROM users WHERE email = :email");
$stmt->execute(['email' => $userInput]);

What It Does:

Prevents injection by parameterizing queries.

What Undercode Say

  • Key Takeaway 1: Foucault’s framework mirrors cybersecurity—knowledge (data) grants power (control over systems).
  • Key Takeaway 2: Attackers exploit gaps in “knowledge” (e.g., unpatched systems, misconfigurations).

Analysis:

Foucault’s insight that power operates through systems of knowledge is evident in cyber warfare. For example, ransomware gangs leverage stolen data (knowledge) to extort organizations (power). Defenders must adopt Foucault’s lens: audit systems relentlessly, question defaults, and recognize that visibility (logs, monitoring) is a form of control.

Prediction

As AI automates knowledge extraction (e.g., LLMs analyzing breach patterns), the “power/knowledge” dynamic will intensify. Organizations ignoring this interplay will face systemic breaches, while those embracing transparency and continuous learning will dominate the next era of cybersecurity.
