Budget-Friendly Cybersecurity Initiatives for Small Businesses

Effective cybersecurity for small businesses hinges on a layered defense strategy—combining preventive measures, monitoring, incident response, and employee training—without relying on enterprise-grade tools. Below are five initiatives categorized by their cost range, implementation complexity, and protective value, ensuring alignment with operational constraints while mitigating the most critical risks.

Top 5 Cybersecurity Projects for Small Businesses Under $500

Cost-Effectiveness Principle: Prioritize projects that address the top 3 attack vectors for SMBs—phishing, unpatched vulnerabilities, and weak authentication—before investing in broader security controls.

1. Multi-Factor Authentication (MFA) Enforcement for Critical Accounts

   Cost: $0–$100 (per user, if using free tiers of services like Google Authenticator, Duo Free, or Microsoft Authenticator).
   Implementation Time: 1–2 hours per user.
   Why It Matters: 80% of breaches exploit weak or stolen credentials (Verizon DBIR 2023). MFA reduces credential-based attacks by 99.9% (Microsoft Security).

   Steps:

   1. Select a free MFA provider (e.g., Authy, Duo Free, or Microsoft Authenticator).
   2. Integrate with email (e.g., Gmail, Outlook) or cloud services (e.g., AWS, Azure) via provider-specific APIs or plugins.
   3. Enforce MFA for administrators, finance, and remote access accounts first, then expand to all users.
   4. Use conditional access policies (if available) to block legacy authentication methods (e.g., SMS-based MFA for high-risk accounts).

   Example Command (Linux/Cloud):
   

   Enable MFA for SSH (using Google Authenticator)

   sudo apt install libpam-google-authenticator
google-authenticator


2. Endpoint Protection with Open-Source AV and EDR

   Cost: $0–$300 (for 10–20 devices; ClamAV + OSSEC or Windows Defender + Snort).
   Implementation Time: 4–8 hours (initial setup).
   Why It Matters: 60% of SMB breaches involve malware (IBM Cost of a Data Breach Report 2023). Free/low-cost AV + EDR provides real-time threat detection without subscription fees.

   Recommended Tools:

   • ClamAV (Linux/Windows): Lightweight antivirus with signature-based scanning.
   • OSSEC (Linux/Windows): Host-based intrusion detection (HIDS) with log analysis.
   • Snort (Linux): Network intrusion detection (NIDS) for traffic monitoring.
   • Windows Defender ATP (Free Tier): Cloud-delivered protection with basic EDR features.

   Installation Guide (Linux - ClamAV + OSSEC):
   

   Install ClamAV (Debian/Ubuntu)

   sudo apt update && sudo apt install clamav clamav-daemon
sudo freshclam # Update virus signatures
sudo systemctl enable --now clamav-freshclam clamav-daemon


   Install OSSEC (Linux)

   wget -c https://github.com/ossec/ossec-hids/archive/refs/tags/v3.6.0.tar.gz
   tar -xzf v3.6.0.tar.gz
   cd ossec-hids-3.6.0
   sudo ./install.sh
   

   Configure OSSEC (edit /var/ossec/etc/ossec.conf)

   <ossec_config>
   <global>
   <name>Your_Organization</name>
   <email_notification>admin@example.com</email_notification>
   </global>
   <ossec_config>
   <rootcheck>
   <disabled>no</disabled>
   <frequency>6</frequency>
   </rootcheck>
   </ossec_config>
   </ossec_config>
   sudo systemctl restart ossec
   

3. Network Traffic Monitoring with Wireshark/TShark

   Cost: $0 (open-source).
   Implementation Time: 2–4 hours (initial setup + rule tuning).
   Why It Matters: Unauthorized network activity accounts for 45% of SMB breaches (CISA). Passive monitoring detects lateral movement and data exfiltration early.

   Tools Comparison:

   Feature	Wireshark (GUI)	TShark (CLI)	Snort (NIDS)
   Platform Support	Windows/Linux/macOS	Linux/macOS/WSL (Windows)	Linux (Windows via WSL)
   Ease of Use	High (GUI-based)	Medium (CLI commands)	Low (Rule-based)
   Real-Time Analysis	Yes	Yes (via pipes)	Yes (with rules)
   Scalability	Low (single machine)	Medium (scriptable)	High (distributed)
   Rule Customization	Limited (filters)	High (custom scripts)	Very High (Snort rules)

   Example TShark Command for Basic Monitoring:
   

   Capture traffic on interface eth0, filter for HTTP/SMB, and log to file

   ts shark -i eth0 -f "port 80 or port 443 or port 445" -w capture.pcap
   

   Analyze for suspicious activity (e.g., large outbound transfers)

   ts shark -r capture.pcap -Y "http.request.method == 'POST' and http.file_data > 1000000"
   

   Snort Rule Example (Detect Brute Force):
   

   Edit /etc/snort/rules/local.rules

   alert tcp any any -> $HOME_NET 22 (msg:"SSH Brute Force Attempt"; flow:to_server,established; threshold:type threshold, track by_src, count 5, seconds 60; classtype:attempted-recon; sid:1000001; rev:1;)


DIY Cybersecurity Projects for Home Users

Cybersecurity threats targeting home networks have surged alongside the proliferation of IoT devices and remote work setups. Many users lack awareness of basic defensive measures, leaving them vulnerable to exploits like unauthorized access, data leaks, or botnet recruitment. Implementing cost-effective solutions—such as custom firewalls, router hardening, and traffic monitoring—can mitigate risks without requiring specialized hardware or subscriptions. Below are actionable steps to fortify a home network using open-source tools and low-cost hardware, ensuring privacy and resilience against common cyber threats.


Setting Up a Home Firewall with pfSense or OPNsense on Low-Cost Hardware

A dedicated firewall appliance enhances security by inspecting and filtering traffic before it reaches internal devices. pfSense and OPNsense are open-source firewall distributions that can be installed on a Raspberry Pi 4 (or similar ARM-based hardware) for under $100, offering advanced features like intrusion detection (IDS), VPNs, and granular rule sets.

Hardware Requirements:


4. Raspberry Pi 4 (4GB RAM) or Intel NUC (for x86 compatibility).
5. MicroSD card (32GB+) or USB boot drive for the OS.
6. Ethernet adapter (if Wi-Fi is not required for firewall operations).
7. Power supply (5V/3A for Pi 4).

Installation Steps:
1. Download the appropriate image (ARM64 for Pi 4 or x86-64 for Intel hardware) from the pfSense or OPNsense websites.
2. Flash the image to the SD card/USB using BalenaEtcher or Rufus (Windows) / dd (Linux).
3. Boot the device and follow the on-screen setup, configuring:


8. LAN interface (internal network).
9. WAN interface (ISP connection).
10. Static IP for management (e.g., `192.168.1.1`).
4. Complete the web installer via a browser, setting a strong admin password and enabling SSH (for remote management if needed).

Firewall Rules for Common Threats:
To block port scans, DDoS attempts, and malicious probes, apply the following rules under Firewall > Rules > LAN:


Rule Description	Action	Protocol	Source	Destination	Ports	Notes
Block ICMP (Ping) Floods	Block	ICMP	Any	Any	Echo Request	Mitigates basic DDoS attempts.
Block Unauthorized Port Scans	Block	TCP/UDP	Any	Any	`1-1023` (except 80,443)	Restricts common scan targets.
Rate-Limit SSH Brute Force	Limit (10/min)	TCP	Any	WAN Address	22	Prevents credential stuffing.
Drop Malformed Packets	Drop	Any	Any	Any	Any	Rejects fragmented/oversized traffic.
Block Known Botnet C2 IPs	Block	Any	Custom List	Any	Any	Use AlienVault OTX or FireHOL lists.

Advanced Protection:

11. Enable Intrusion Detection (Suricata/Snort) under Services > Intrusion Detection to detect exploits (e.g., EternalBlue, Mirai).
12. Configure Outbound NAT to mask internal IPs and log suspicious outbound connections.
13. Set up VPN (WireGuard/OpenVPN) for secure remote access.

Hardening a Home Router Checklist with Visual Settings

Most consumer routers ship with default configurations vulnerable to exploitation. Below is a checklist to secure a typical TP-Link, ASUS, or Netgear router, with descriptions of critical settings (visualized where applicable):

1. Disable WPS (Wi-Fi Protected Setup)


14. Location: Wireless Settings > Security
15. Action: Uncheck WPS PIN and WPS Push Button.
16. Why: WPS uses weak encryption (e.g., PIN brute-forcing) and has been exploited in attacks like Reaver.

2. Enable SPI Firewall (Stateful Packet Inspection)


17. Location: Security > Firewall (varies by model; often labeled SPI Firewall or Advanced Firewall)
18. Action: Toggle ON and set Default Deny for unknown traffic.
19. Visual: A slider or checkbox labeled "Enable SPI Firewall" with a confirmation dialog.

3. Update Firmware to Latest Version


20. Location: Administration > Firmware Upgrade
21. Action: Check for updates and install immediately.
22. Why: Outdated firmware is a primary attack vector (e.g., VPNFilter malware exploited unpatched routers).

4. Change Default Admin Credentials


23. Location: Administration > Password
24. Action: Set a 12+ character password with mixed case, numbers, and symbols.
25. Visual: A password strength meter should show "Strong" after entry.

5. Disable Remote Management


26. Location: Administration > Remote Access
27. Action: Disable HTTP/HTTPS remote login unless absolutely necessary.
28. Why: Prevents unauthorized access via the internet (e.g., default credentials still used in botnets).

6. Segment IoT Devices on a Guest Network


29. Location: Wireless > Guest Network
30. Action: Create a separate SSID (e.g., `IoT-Guest`) with no internet access to LAN.
31. Visual: A dropdown to select "Isolate from LAN" or "Block Internet Access."

7. Disable UPnP (Universal Plug and Play)


32. Location: Advanced > UPnP
33. Action: Turn OFF.
34. Why: UPnP can be abused to open ports for malware (e.g., Emotet exploits).

8. Enable MAC Address Filtering (Optional)


35. Location: Wireless > Security > MAC Filter
36. Action: Whitelist trusted devices.
37. Caution: Not foolproof; attackers can spoof MAC addresses.

9. Change Default SSID and Disable SSID Broadcast


38. Location: Wireless > Basic Settings
39. Action: Rename SSID (e.g., `HomeWiFi_2024`) and uncheck Broadcast SSID.
40. Why: Reduces visibility to casual scanners.

10. Monitor Connected Devices Regularly


41. Location: Network > DHCP Clients
42. Action: Review the list weekly for unknown devices.
43. Visual: A table showing Device Name, MAC Address, IP, and Connection Time.

Securing IoT Devices with Free Tools: Fing and Wireshark

IoT devices (e.g., smart cameras, plugs, thermostats) often ship with default credentials, unpatched firmware, or insecure protocols, making them prime targets. Fing and Wireshark can identify vulnerabilities without requiring specialized knowledge.

Step 1: Scan the Network with Fing


44. Download Fing (Android/iOS/Windows) from the official site.
45. Run a Network Scan to list all connected devices, noting:
46. Device Name (e.g., `TP-Link_Camera`).
47. MAC Address (e.g., `00:11:22:AA:BB:CC`).
48. IP Address (e.g., `192.168.1.100`).
49. Manufacturer (e.g., `Xiaomi`, `TP-Link`).

Step 2: Identify Vulnerable Devices
Use Fing’s Device Details to check for:


50. Default credentials (e.g., `admin/admin`).
51. Open ports (e.g., `23/TCP` for Telnet, `7547/TCP` for TR-069).
52. Outdated firmware (compare against manufacturer’s latest version).

Step 3: Analyze Traffic with Wireshark


53. Capture packets on the router or a device connected to the same network.
54. Filter for suspicious activity using:
55. `http.request.method == "POST"` (brute-force attempts).
56. `dns.qry.name contains "malware"` (C2 domain checks).
57. `tcp.port == 443 && tls.handshake.type == 1` (unencrypted HTTPS traffic).

Free and Low-Cost Tools for Vulnerability Assessment

Vulnerability assessment is a critical component of cybersecurity, enabling organizations and individuals to identify weaknesses in systems before malicious actors exploit them. Free and low-cost tools provide accessible means to conduct scans, detect vulnerabilities, and prioritize remediation efforts without substantial financial investment. This section evaluates open-source and freemium solutions, demonstrates practical usage in controlled environments, and offers structured methodologies for manual assessments, ensuring actionable insights for users of varying technical expertise.


Comparison of Free Vulnerability Scanners and Sample Scan Findings

Open-source and freemium vulnerability scanners offer varying capabilities in terms of detection depth, ease of use, and compatibility with target systems. Below is a comparative analysis of three widely used tools—OpenVAS, Nessus Home (free tier), and Nikto—with hypothetical scan results to illustrate their strengths and limitations in a test environment.

Key Considerations for Selection:


58. OpenVAS (Greenbone Vulnerability Management): Open-source, highly customizable, and supports extensive plugin libraries for network and web application scanning. Ideal for organizations requiring granular control over scan parameters.
59. Nessus Home (Tenable): Freemium version with a limited scan depth (e.g., no compliance checks) but user-friendly interface and automated reporting. Suitable for small businesses or non-technical users.
60. Nikto: Specialized in web server vulnerability assessment, detecting outdated software, misconfigurations, and default files. Lightweight and fast, but lacks network-level scanning capabilities.

Hypothetical Scan Findings (Test Environment: Ubuntu 20.04 LTS with Apache/2.4.41, PHP 7.4.3, and a deliberately misconfigured WordPress 5.8 instance):

OpenVAS Findings:


Critical: Unpatched PHP vulnerability (CVE-2021-23037) with a CVSS score of 9.8.

High: WordPress plugin "Elementor" outdated (version 3.1.0 vulnerable to RCE via CVE-2021-34643).

Medium: Apache HTTP Server exposes version details in HTTP headers (risk of fingerprinting).

Nessus Home Findings:


Critical: Same PHP vulnerability detected, but with fewer contextual details (e.g., no plugin-specific analysis).

Medium: WordPress core outdated (5.8 → 5.8.1 patch available), but no plugin-level granularity.

Low: Default WordPress "readme.html" file accessible (informational, not exploitable).

Nikto Findings:


High: WordPress version disclosure in HTTP headers (risk of targeted attacks).

Medium: PHP self-info page accessible (default installation artifact).

Low: Apache server signature exposed (minor fingerprinting risk).

Recommendation:
For comprehensive network/web assessments, OpenVAS is preferred due to its depth. Nessus Home suits users needing quick, high-level scans with minimal configuration. Nikto excels in web-specific audits but should be combined with other tools for full coverage.


Metasploit Framework Free Tier for Controlled Vulnerability Testing

The Metasploit Framework (free tier) provides a powerful platform for ethical hackers to test common vulnerabilities in a legal, isolated environment. Below are step-by-step commands to identify SQL Injection (SQLi) and Cross-Site Scripting (XSS) vulnerabilities in a deliberately vulnerable test system (e.g., DVWA or OWASP Juice Shop).

Prerequisites:


61. Metasploit installed (`msfconsole` command).
62. Target system running a vulnerable web application (e.g., DVWA with "low" security level).
63. Legal authorization for testing (e.g., personal lab or authorized penetration test).

Step 1: Launch Metasploit and Load Auxiliary Modules

msfconsole
use auxiliary/scanner/http/sql_injection

Step 2: Configure the Module for SQLi Detection

set RHOSTS # Replace with test system IP
set TARGETURI /dvwa/vulnerabilities/sqli/
set HTTPDELAY 1 # Adjust delay between requests
set THREADS 5 # Concurrent threads for faster scanning
run

Expected Output:


64. Detection of blind SQLi (e.g., time-based delays or error messages) in input fields.
65. Example finding: `GET parameter 'id' is vulnerable to SQL injection via UNION-based attacks.`

Step 3: Test for XSS Using the XSS Scanner

use auxiliary/scanner/http/xss
set RHOSTS set TARGETURI /dvwa/vulnerabilities/xss_s/
set PAYLOADS # Custom payload file (e.g., ``)
run

Expected Output:


66. Identification of reflective XSS in user input fields (e.g., search boxes).
67. Example finding: `Parameter 'name' reflects user input without sanitization, allowing JavaScript execution.`

Step 4: Exploit Detection (Optional)
For confirmed vulnerabilities, use Metasploit’s exploit modules:

use exploit/multi/http/php_cgi_arg_injection
set RHOSTS set TARGETURI /cgi-bin/test.cgi
exploit

Note: Exploitation should only occur in authorized environments with explicit permission.


Manual Vulnerability Assessment Checklist for OWASP Top 10

A structured checklist tailored to non-technical users ensures systematic evaluation of web applications against the OWASP Top 10 risks. Below is a template with actionable fixes for each category.

Purpose:


68. Standardize vulnerability assessment processes.
69. Provide clear remediation steps without requiring coding expertise.
70. Serve as a baseline for third-party audits or internal reviews.

Checklist Structure:

1. Injection (e.g., SQLi, OS Command Injection)
   
2. Test: Enter single quotes (`'`) or SQL keywords (`DROP TABLE`) into input fields (e.g., login forms).
3. Finding: Database errors or unexpected behavior indicate vulnerability.
4. Fix:
   • Use prepared statements (parameterized queries) for database interactions.
   • Implement input validation (e.g., regex for alphanumeric-only fields).
   • Apply Web Application Firewalls (WAFs) like ModSecurity with OWASP Core Rule Set.
5. Broken Authentication (e.g., Weak Password Policies, Session Hijacking)
   
6. Test: Attempt default credentials (e.g., `admin:admin`), brute-force attacks, or session fixation.
7. Finding: Successful login with weak credentials or session ID persistence across logouts.
8. Fix:
   • Enforce multi-factor authentication (MFA) for admin accounts.
   • Use secure session tokens (HTTP-only, SameSite cookies) with short expiration.
   • Rate-limit login attempts to prevent brute force.
9. Sensitive Data Exposure (e.g., Hardcoded Credentials, Unencrypted Data)
   
10. Test: Inspect network traffic (using browser dev tools) for plaintext passwords or credit card numbers.
11. Finding: HTTP (not HTTPS) connections or cleartext data in error messages.
12. Fix:
    • Enforce TLS 1.2+ and disable outdated protocols (SSLv3, TLS 1.0/1.1).
    • Encrypt sensitive data at rest (AES-256) and in transit (TLS).
    • Mask error messages to avoid exposing stack traces with credentials.
Additional Notes:

71. For non-technical users: Highlight critical items with bold text (e.g., "Immediately disable default credentials").
72. Prioritization: Rank findings by impact (e.g., SQLi = Critical, weak password policies = High).
73. Tools to Assist: Use OWASP ZAP (free) for automated checks alongside manual testing.

Nmap is a versatile tool for discovering open ports, services, and potential vulnerabilities in a network. Below is a Python script to automate basic scans and a breakdown of key Nmap flags for service enumeration.

Python Script for Automated Scanning (Using `subprocess`):

#!/usr/bin/env python3
import subprocess
import argparse

def run_nmap_scan(target, scan_type="syn"):
"""Execute Nmap scan and return formatted output."""
flags = {
"syn": "-sS -T4 -Pn", # SYN


Educational Cybersecurity Projects for Students

Cybersecurity education for students fosters critical thinking, technical skills, and awareness of digital threats. Hands-on projects bridge theoretical knowledge with practical application, enabling learners to explore encryption, network security, and social engineering in controlled environments. These initiatives align with global frameworks like NICE Cybersecurity Workforce Framework and ISTE Standards for Students, ensuring relevance to real-world cybersecurity challenges. Below are structured projects designed for classroom or self-paced learning, leveraging free and open-source tools to minimize cost barriers.


Project Outline: Teaching Basic Cryptography with Free Tools

Cryptography introduces students to encryption principles, key management, and digital signatures—foundational concepts for secure communications. This project uses GnuPG (GPG) for encryption/decryption and Cryptool for interactive cryptanalysis, reinforcing both theoretical and hands-on skills.

Lesson Plan Structure (3 Sessions, 90 minutes each):


74. Session 1: Symmetric and Asymmetric Encryption Fundamentals
Students explore how symmetric keys (AES) and asymmetric keys (RSA) work through Cryptool’s visual tools, analyzing encryption/decryption processes. A live demo of GPG encrypting a text file with a passphrase demonstrates real-world application.

Example: A student encrypts a message with GPG using `gpg --encrypt --recipient student@example.com file.txt` and decodes it with the private key, observing the role of digital certificates.

75. Session 2: Practical GPG Workflow
Hands-on lab where students:

76. Generate and manage key pairs (`gpg --gen-key`).
77. Sign and verify files to simulate digital signatures.
78. Troubleshoot common errors (e.g., expired keys, incorrect passphrases).
    • Key Management Exercise: Students create a backup of their GPG keyring and restore it on a new system, documenting steps in a lab report.
    • Security Analysis: Compare the strength of 1024-bit vs. 4096-bit RSA keys using Cryptool’s brute-force simulation.
79. Session 3: Cryptanalysis and Real-World Scenarios
Students use Cryptool to break simple ciphers (e.g., Caesar shift, Vigenère) and discuss ethical implications. A debate follows on quantum computing’s threat to RSA, referencing Shor’s algorithm and NIST’s post-quantum cryptography standards.

Student Deliverables:


80. Lab Report: Document encryption/decryption workflows, including screenshots of GPG commands and Cryptool simulations.
81. Reflective Essay (500 words): Compare symmetric vs. asymmetric encryption trade-offs, citing use cases (e.g., TLS for HTTPS, PGP for emails).
82. Group Presentation: Demonstrate a secure communication scenario (e.g., encrypting a "top-secret" message between two peers).

Hands-On Lab Guide: Building a Secure Wi-Fi Network with Raspberry Pi and WPA3

This project teaches network security fundamentals by configuring a Raspberry Pi as a WPA3-Enterprise access point (AP), including authentication via 802.1X/RADIUS. Students learn to mitigate common Wi-Fi vulnerabilities (e.g., brute-force attacks, rogue APs) while applying concepts like EAP-TLS and PSK security.

Prerequisites:


83. Raspberry Pi 4/5 with Raspberry Pi OS (64-bit).
84. USB Wi-Fi adapter (e.g., TP-Link TL-WN725N) for dual-band support.
85. Free tools: `hostapd`, `dnsmasq`, `wpa_supplicant`.

Step-by-Step Implementation:

1. Hardware Setup and OS Configuration
   Install Raspberry Pi OS Lite, update packages (`sudo apt update && sudo apt upgrade -y`), and enable Wi-Fi hotspot mode:

   sudo raspi-config → Interfacing Options → Wi-Fi → Enable hotspot.

   Configure `/etc/dhcpcd.conf` to assign static IPs to the Pi’s Ethernet/Wi-Fi interfaces.

2. Configure WPA3-Personal (PSK) or Enterprise (802.1X)
   • WPA3-PSK (Simpler Setup):
     Edit `/etc/hostapd/hostapd.conf` with:

     interface=wlan0
     driver=nl80211
     ssid=SecureLab
     hw_mode=g
     channel=6
     wpa=3
     wpa_passphrase=YourStrongPassphrase123!

     Start `hostapd` and `dnsmasq`:

     sudo systemctl unmask hostapd
     sudo systemctl enable --now hostapd
     sudo systemctl enable --now dnsmasq
     

   • WPA3-Enterprise (Advanced):
     Requires a RADIUS server (e.g., FreeRADIUS on another Pi). Students configure:
     
   • EAP-TLS with self-signed certificates (`openssl req -x509`).
   • `hostapd.conf` with:

   wpa=3
   wpa_key_mgmt=WPA-EAP
   eap_server=1
   

3. Security Hardening and Troubleshooting
   Students implement the following safeguards:
   • Disable WPS (`wpa_config_file=/etc/hostapd/hostapd.conf` without `wps_conf` line).
   • Enable MAC filtering (though not foolproof) in `hostapd.conf`:

     macaddr_acl=1
     accept_mac_file=/etc/hostapd/allowed_macs.txt
     

   • Log authentication attempts (`logger syslog` in `hostapd.conf`) and analyze logs for failed connections.
   Common Issues and Fixes:

   Issue	Solution
   AP not broadcasting SSID	Verify `hostapd` is running (`sudo systemctl status hostapd`) and check `dmesg` for driver errors.
   WPA3 handshake failures	Ensure client devices support WPA3 (test with `iw list` on Linux clients).
   IP conflicts on the network	Use `dnsmasq` to assign DHCP range (e.g., `dhcp-range=192.168.10.100,192.168.10.200,255.255.255.0,24h`).

4. Performance Testing
   Students use `ping`, `iperf3`, or `speedtest-cli` to measure throughput under different encryption modes (WPA2 vs. WPA3). Document results in a table comparing latency and packet loss.
Student Deliverables:

86. Lab Manual: Step-by-step guide with screenshots of configurations and troubleshooting logs.
87. Security Audit Report: Identify 3 vulnerabilities in their setup (e.g., weak passphrase, unencrypted management interface) and propose mitigations.
88. Demo Video (3–5 minutes): Walkthrough of connecting a device to the AP, including authentication steps.
